Answer:
16, 18 and 20Step-by-step explanation:
x - an integer
2x - an even integer (the first)
Even integers increase by 1 so:
2x+2 - next consecutive integer (the second)
3(2x+2) - three times the second
2x+4 - the third consecutive integer
2x+2x+4 - the sum of the first and third
2x+2x+4+18 - the sum of the first and third increased by 18
2x+2x+4+18 = 3(2x+2)
4x + 22 = 6x + 6
-6 -6
4x + 16 = 6x
-4x -4x
16 = 2x
2x = 16
2x+2 = 18
2x+4 = 20
Check: 16+20+18=54; 3×18=54
A half-marathon is 13.1 miles long. There is a water station every 1 1/3 miles along the race trail and at the finish line. How many water stations are needed for the half-marathon?
choices
15
13
10
11
Answer:
10 water stations are needed
Step-by-step explanation:
To get the number of water- station needed, we simply divide the total length of the half marathon by the distance where we can find a water station
mathematically,
that would be 13.1 divided by 1 1/3
= 13.1 divided by 4/3
= 13.1 * 3/4 = 9.825 which is approximately 10

Find the slope and write an equation of the line which passes through the points. (−3, 9) and (−3, −5)
Answer:
Slope: undefined
Equation: x=-3
Step-by-step explanation:
To find the line that passes through the points, you first want to find the slope. The formula for slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Once we have the slope, we can use any given point to plug in to find the y-intercept.
[tex]m=\frac{-5-9}{-3-(-3)} =\frac{-14}{0}[/tex]
We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.

The circumference of a circular garden is 75.36 feet. What is the radius of the garden
Answer:
12 rounded to a whole number.
Step-by-step explanation:
75.36 divided by pi (3.14159) = 23.987. this is diameter (the length from one side of a circle to the other).
but we need to find the radius. the radius is half way across a circle.
23.987 divided by 2 = 11.993.
round this to a significant whole number and you get 12.
The radius of the garden is,
⇒ r = 12
We have to given that;
The circumference of a circular garden is,
⇒ C = 75.36 feet.
Since, We know that;
The circumference of a circle is,
⇒ C = 2πr
Substitute given values,
⇒ 75.36 = 2 × 3.14 × r
⇒ 75.36 = 6.28 r
⇒ r = 12
Thus, the radius of the garden is,
⇒ r = 12

how many quarters make 40 dollars
can you work it out with quarters
help me please help me please help me please
Given problem;
Number of quarters in $40;
To solve this problem;
Convert the dollar value to cents;100cents = $1
In $40, we would have; 40 x 100 = 4000cents
1 quarter = 25 centsSo, divide 4000cents by 25 to obtain the number of quarters in that amount of dollars;
Number of quarters = [tex]\frac{4000}{25}[/tex] = 160
So there are 160 quarters in $40

Solve equation
t + (-8) + 13 = 43
Answer:
T=38
Step-by-step explanation:
t−8+13=43
Step 1: Simplify both sides of the equation.
t−8+13=43
t+−8+13=43
(t)+(−8+13)=43(Combine Like Terms)
t+5=43
t+5=43
Step 2: Subtract 5 from both sides.
t+5−5=43−5
t=38
Answer:
t= 38
Step-by-step explanation:
t+(-8)+13=43
t-8+13=43
t=43-13+8
t=30+8
t=38

A
m = -5/1
B
m = -1/5
Answer:
Slope: -5/1
Step-by-step explanation:
The slope is always the coefficient of x in y=mx+b, so m is -5 (you don't reverse it)
Answer: A) m = -5/1
Step-by-step explanation: The format of slope intercept form is y=mx+b , therefore M= -5/1.

A is directly proportional to the square root of B
When A = 50, B+4 . Find A in terms of B
Answer:
A=50, B=4
A is directly proportional to the square root of B
name the constant 'k'
A = k*B^0.5
50 = k*4^0.5
50=2k
k=25
=> A =25 root B
i.e, A = 25*B^0.5 (The answer should be written the way it is written in the attached picture)
A written in terms of B is 25√B.
What is direct and inverse proportion ?In direct proportion if one quantity increases the other quantity also increases and vice versa.In case of inverse proportion when one quantity increases the other quantity decreases and vice versa.
According to the given question A is directly proportional to the square root of B.
∴ A = K[tex]\sqrt{B}[/tex]
Given when A = 50 B = 4.
50 = K[tex]\sqrt{4}[/tex]
50 = 2k
k = 25.
So, A =25√B.

A triangle has a base of 10 inches and a height of 8 inches. What percent of the area of the triangle is within 4 inches of the base?
Answer:
40%
Step-by-step explanation:
Firstly
Area of triangle when base is 10 inches and height is 8 inches
= 1/2*b*h
= 1/2*10*8
=40square inch
Again when base =4 inches
= 1/2*4*8
= 16square inches
percent of the area of the triangle is within 4 inches of the base
= 16/40*100%
= 40%
A triangle has an 8-inch height and a 10-inch base. The percent of the area of the triangle is within 4 inches of the base exists 40%.
What is meant by the area of triangle?Area of triangle = 1/2 (b h), where b is the base and h is the height, is the fundamental formula for calculating a triangle's area.
The type of the triangle and the known dimensions can affect other formulas that are used to calculate the area of a triangle.
Given: A triangle has an 8-inch height and a 10-inch base.
Let the equation be
Area of a triangle = (1/2) bh
substitute the values in the above equation, we get
= (1/2) × 8 × 10
= 40 square inches.
Once more with a 4 inch base
= 1/2 × 4 × 8
= 16 square inches.
Within 4 inches of the base, % of the triangle's surface area
= 16/40 × 100%
= 40%
Therefore, the percent of the area of the triangle is within 4 inches of the base exists 40%.
