What is a diameter?Diameter is defined as the length of a line through the center that touches two points on the edge of the circle.
The diameter of the circle can be found through finding first the radius of the circle.
The radius of the circle is half of the diameter. it is the line DI which is also the longer line of the triangle DGI.
Using the Pythagorean formula c² = a² + b²
The lines that represents ;
a= DG
b= EI/2 = 4.8
C= DI = ?
C² = DI
a² = 1.8²
b² = (9.5/2)² = 4.8²
c² = 2.24 + 23.04 = 25.28

How to Write the Equation of Parallel Lines?The equation of a line, in slope-intercept form is y = mx + b, if two lines are parallel to each other, then the value of the slope, m, would be the same for both of them.
Given the equation, 2x + y = -4, rewrite the equation in slope-intercept form to determine the slope (m):
2x + y = -4
y = -2x - 4
The slope (m) is -2.
This means the line that passes through (1, 0) will also have a slope of -2. Substitute m = -2 and (x, y) = (1, 0) into y = mx + b, to find the y-intercept (b) of the line:

Leah walks to soccer practice on Saturday. She leaves her home and walks 6 blocks north. Leah then turns east and walks 4 more blocks to the soccer field. How far is the soccer field from leah’s home ? Round your answer to the nearest tenth.
Answers
Answer: The soccer field is about 8.6 blocks away from Leah's home.
Step-by-step explanation:
The soccer field is about 8.6 blocks away from Leah's home.
Leah walks 6 blocks north and 4 blocks east. To find the total distance she walked, we can use the Pythagorean theorem. The theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
The distance is the square root of (6 blocks)^2 + (4 blocks)^2 = 36 + 16 = 52 then square root of 52 = 7.21
The distance of the soccer field from Leah’s home is 7.21 blocks, but it can be rounded to nearest tenth which is 8.6
Danny takes a rectangular piece of fabric and cuts from one corner to the opposite corner. If
the piece of fabric is 9 centimeters long and 12 centimeters wide, how long is the diagonal
cut that Danny made?
Answers
Answer: To find the length of the diagonal cut, we can use the Pythagorean theorem.
The diagonal cut is the hypotenuse of a right triangle, with legs of length 9 and 12.
The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the legs. So, the length of the diagonal cut is the square root of (9^2 + 12^2)
So, the length of the diagonal cut is √(9^2 + 12^2) = √(81 + 144) = √225 = 15cm
Therefore, the diagonal cut that Danny made is 15 centimeters long.

[4 -7] * [a b] * = [1 0]
[-1 2] [c d] [0 1]
4 * a + (-7) * c = 1
4 * b + (-7) * d = 0
-1 * a + 2 * c = 0
-1 * b + 2 * d = 1
4a - 7c = 1 ==> equation 1
4b - 7d = 0 ==> equation 2
-a + 2c = 0 ==> equation 3
-b + 2d = 1 ==> equation 4
(-b + 2d = 1) * 4 ==> make -b into -4b
-4b + 8d = 4
+ (4b - 7d = 0)
-4b+4b + 8d-7d = 4+0 ==> add equations 2 and 4 to cancel the variable b
8d-7d = 4 ==> -4b+4b=0 and adding anything by 0 will result in itself: 0+3=3
d = 4
-b + 2d = 1
-b + 2(4) = 1 ==> substitute 4 for d
-b + 8 = 1 ==> simplify
-b = -7 ==> subtract 8 on both sides
b = 7 ==> simplify
Since we got the values of b and d, the matrix now looks like this:
[4 -7] * [a 7] * = [1 0]
[-1 2] [c 4] [0 1]
Now solve for a and c using equations 1 and 3:
4a - 7c = 1 ==> equation 1
-a + 2c = 0 ==> equation 3
(-a + 2c = 0) * 4 ==> make -a into -4a
-4a + 8c = 0
+ (4a - 7c = 1)
-4a+4a + 8c-7c = 0+1 ==> add equations 1 and 3 to cancel the variable b
8c-7c = 1 ==> -4a+4a=0 and adding anything by 0 will result in itself: 0+3=3
c = 1
-a + 2c = 0
-a + 2(1) = 0 ==> substitute 1 for c
-a + 2 = 0 ==> simplify
-a = -2 ==> subtract 2 on both sides
a = 2 ==> simplify
Since we got the values of a and c, the matrix now looks like this:

The slope of a line can be used when building a ramp. Gordon is helping to build a wheelchair ramp for a neighbor's house. For every 12 inches of horizontal distance, the height of the ramp increases 1 inch.
Question 1
Part A
The height of the ramp when it connects to the house is 9 inches. What is the length of the ramp in yards?
Part B
Explain how you determined the length.
Enter the correct answers in the boxes.
The ramp is 9 inches tall, so the length of the ramp is 9×
=
inches, which is equal to
feet, and that is equal to
yards.
Answers
Answer:
Part A:
To find the length of the ramp in yards, we need to first determine the horizontal distance covered by the ramp. The slope of the ramp is 1/12, meaning that for every 12 inches of horizontal distance, the height of the ramp increases by 1 inch. Since the height of the ramp when it connects to the house is 9 inches, we can use this information to determine the horizontal distance covered by the ramp.
9 inches / (1/12) = 108 inches
To convert inches to yards, we divide by 36, so
108 inches / 36 inches/yard = 3 yards
Part B:
To determine the length of the ramp, I used the information provided about the slope of the ramp and the height of the ramp when it connects to the house. I used the slope of the ramp (1/12) to calculate the horizontal distance covered by the ramp. Then I converted the horizontal distance from inches to yards by dividing by 36. Finally, I obtained 3 yards as the length of the ramp.
Answer:
Part A = 3 yards
Part B = 9 x 12 = 108 inches = 9 feet = 3 yards
Step-by-step explanation:
Part A
1 inch height - 12 inches length
9 inches height - 9 x 12 = 108 inches length
36 inches = 1 yard
108 inches = 108/36 = 3 yards
Part B
Shown above
The ramp is 9 inches tall, so the length of the ramp is 9 x 12 = 108 inches.
1 feet = 12 inches
108 inches = 108/12 feet = 9 feet
1 yard = 3 feet
9 feet = 3 yards.

Answers
The plane weights 1988 pounds when it has 16 gallons of fuel on board. It is 2175 pounds heavier when carrying 50 gallons of fuel. w= 2500 .
How much does the airplane weigh if it is carrying ?The following correlation is true if the relationship between weight and fuel consumption is linear:
[tex]$\frac{2175 \text { pounds }-1988 \text { pounds }}{50 \text { gallons-16gallons }}=\frac{W-1988 \text { pounds }}{64 \text { gallons-16galons }}$[/tex]
We resolve this equation:
w = 2500.
Assume that the weight of an airplane, measured in pounds, is a linear function of the fuel tank's capacity, measured in gallons. The aircraft weighs 2030 pounds while carrying 20 gallons of fuel. It weighs 2225 pounds while carrying 50 gallons of fuel. It weighs 2338 pounds while carrying 52 gallons of fuel.

A quadratic equation is an equation of the form ax² + bx + c = 0, where x is the variable and a, b, and c are constants.
5/x - 2/x² = 2
The LCM of x and x² is x². So we have:
(5x - 2)/x² = 2
Cross multiply:
5x - 2 = 2x²
2x² - 5x + 2 = 0
Factorize:
(2x - 1)(x - 2) = 0
2x - 1 = 0 or x - 2 = 0
2x = 1 or x = 2
x = 1/2 or x = 2
Thus, x₁ = 1/2 and x₂ = 2

The smiley face is solved to get a value of 72
How to solve to get the value of the smiley faceThe solution to the value of the smiley face is solved by forming some equations
Using the third row that have only squares
8 square - 6 square + 3 square = 60
2 square + 3 square = 60
5 square = 60
dividing through by 5
square = 60 / 5 = 12
hence a square is 12
Using the second row
12 square + 5 star = 234
substituting a square = 12
12 * 12 + 5 star = 234
144 + 5 star = 234
5 star = 234 - 144
5 star = 90
dividing through by 5
star = 90 / 5 = 18
hence a star is 18
using the first row
square + 3 triangle + star = 57
substituting square = 12 and star = 18
12 + 3 triangle + 18 = 57
3 triangle + 30 = 57
3 triangle = 57 - 30
3 triangle = 27
dividing through by 3
triangle = 27 / 3 = 9
hence triangle = 9
solving for the smiley face
substituting the values of the figures
18 (9 + 18 - 12) + 12 (18 + 9 + 9) = smiley face
solving the parenthesis
smiley face = 18 (15) + 12 (36)
smiley face = 18 * 15 + 12 * 36

To maximize the volume we need to cut squares with a side length of 20cm.
How to maximize the volume?
Suppose that the length of the sides of the squares that we cut is X, that will be the height of the box, then its volume will be:
V = (60 - X)*(60 - X)*X
Now we just need to maximize that cubic equation.
V = X*( X^2 - 120*X + 3600)
V = X^3 - 120X^2 + 3600X
To maximize this we need to differentiate it and find the value of X that makes it equal to zero, we will get:
V' = 3*X^2 - 2*120*X + 3600
V' = 3*X^2 - 240*X + 3600
Now we make this equal to zero:
3*X^2 - 240*X + 3600 = 0
The solutions are given by the quadratic formula:
[tex]X = \frac{240 \pm \sqrt{240^2 - 4*3600*3} }{2*3} \\\\\\X = \frac{240 \pm 120 }{6}[/tex]
We will take the smaller solution:
X = (240 - 120)/6 = 20
Because the other solution makes the volume equal to zero.
This means that we need to cut squares with a side length of 20 cm.

Date Page A merchant bought a quintal of potatoes for Rs 4000. He sold all potatoes at Rs 390 per kg.
Find his profit or loss.
Answers
Answer: The merchant made a profit of Rs 35,000 by selling the potatoes.
Step-by-step explanation:
To find the profit or loss of the merchant, we first need to calculate the revenue he earned from selling the potatoes.
A quintal is a unit of weight equivalent to 100 kg, therefore, the merchant bought 100 kg of potatoes.
If the merchant sold all potatoes at Rs 390 per kg, the revenue would be 100 * 390 = Rs 39,000.
To find the profit or loss, we need to compare the revenue to the cost of the potatoes.
If the merchant bought a quintal of potatoes for Rs 4000, the cost is Rs 4000.
To calculate the profit or loss, we can use the following formula:
Profit or loss = Revenue - Cost
Using this formula, we can calculate the profit or loss as:
Profit or loss = 39,000 - 4,000 = Rs 35,000
So, the merchant made a profit of Rs 35,000 by selling the potatoes.
It is important to note that when calculating the profit or loss, we need to make sure that the units of measure for cost and revenue are the same.
When given a set of cards laying face down that spell P, E, R, C, E, N, T, S, determine the probability of randomly drawing a vowel.
A. two eighths
B. six eighths
C. two sevenths
D. six sevenths
Answers
Probability is a metric used to express the possibility or chance that a particular event will occur. Two eighths of a vowel will be drawn at random. Option A is correct.
What is probability?A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
The formula for calculating probability is expressed as:
Probability = expected/total outcome
If the given a set of cards laying face down that spell P, E, R, C, E, N, T, S, then the total outcome is:
n(S) =8
If a vowel is selected randomly, hence the expected outcome is;
E = {E, E}
n(E) = 2
P(vowel) = 2/8
Hence the probability of randomly drawing a vowel is two eighths

Step-by-step explanation:
The stopping distance , D, of a car after the brakes are applied varies directly as the square of the speed , S, of the car. If a car traveling at a speed of 36 miles per hour can stop in 53 feet, what is the stopping distance of a car traveling at 70 miles per hour? Round your answer to the nearest foot.
Answers
Answer: There is no way 200 is the answer. it should be 103.055
Step-by-step explanation: See, 36 miles can stop in 53 feet. We want to know how many feet are there when 70 miles fast. We can write that as 36/53 = 70/x. 36 corresponds to 70 and 53 corresponds to x. Do it and you get 103.055

During a gift exchange, ten different gifts
are labeled 1-10 and placed in a pile.
Each person takes a turn selecting a gift
without replacing it. What is the
probability that the first gift chosen is gift
#3 and the second is gift #9?
Answers
Using the given conditions in the question,the probability that the first gift chosen is gift #3 and the second is gift #9 is (1/10) * (1/9) = 1/90.
What is probability?Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, with 0 indicating that an event is impossible and 1 indicating that an event is certain. Events with a probability of 0.5 or greater are considered likely, while those with a probability less than 0.5 are considered unlikely. The probability of all possible events in a given situation must add up to 1. In mathematical terms, probability is the ratio of the number of favorable outcomes to the total number of possible outcomes.
How can you measure the chance of something happening?The chance of something happening can be measured by probability. It's a number between 0 and 1, where 0 means it's impossible for the event to happen and 1 means it's certain to happen. The closer the number is to 1, the more likely the event is to happen.
The probability that the first gift chosen is gift #3 and the second is gift #9 is (1/10) * (1/9) = 1/90. This is because the probability of choosing any specific gift on the first turn is 1/10, and the probability of choosing any specific gift on the second turn, given that there are now 9 gifts left in the pile, is 1/9. Multiplying these probabilities together gives the overall probability of the first gift being #3 and the second gift being #9.
