Step-by-step explanation:
Answer:
Step-by-step explanation:
If the 2 is a number, then distribute it to the b^3 to get 2b^3.
If the 2 is an exponent, then multiply the 3 and 2 to get b^6.
The value of y varies directly with x. If x = 5 when y = 12, what is the value of x when y = 30?
Answer:
12.5
Step-by-step explanation:
y= kx
k= y/x
x= 5, y= 12
k = 12/5
Therefore the value of x when y is 30 can be calculated as follows
y = kx
30= 12/5x
x= 30÷12/5
x= 30× 5/12
x= 150/12
x= 12.5
Bernice monthly paycheck can be represented by p(d) = 21od + 1100. She also earns money babysitting which can be represented by b(d) = 36d + 100. In both functions, d represents the number of weekdays. Write a function, t(d) , that represents Bernice's total monthly income.
Answer:
t(d) = 246d + 1200
Step-by-step explanation:
t(d) = p(d) + b(d)
Where,
t(d) = Bernice's total monthly income
p(d) = monthly paycheck
b(d) = babysitting earnings
d = number of weekdays
p(d) = 210d + 1100
b(d) = 36d + 100
t(d) = p(d) + b(d)
= (210d + 1100) + (36d + 100)
= 210d + 1100 + 36d + 100
= 246d + 1200
t(d) = 246d + 1200
A retail shop is replacing their flooring with new tile. New tile will go in the point shaded area below. Determine the total square feet of tile needed to complete the job.
Answer:
137 ft²
Step-by-step explanation:
The shop is rectangular in shape. The area of a rectangle is given by:
Area = length * width
Since the length of the shop = 20 ft and the width = 10 ft, therefore:
Area of the shop = length * width = 20 ft * 10 ft = 200 ft²
The part that would not be tiled is of triangular shape. The area of a triangle is given as:
Area = (1/2) * base * height
The base of the triangle = 18 ft, the height = 7 ft. Hence:
Area of non tiled part = (1/2) * base * height = (1/2) * 18 ft * 7 ft = 63 ft²
The total square feet of tile needed to complete the job = Area of shop - Area of non tiled part
The total square feet of tile needed to complete the job = 200 ft² - 63 ft² = 137 ft²

Answer:
47.5°
Step-by-step explanation:
(2x+10)°+75°= 180°------ sum of angles of a triangle
or, (2x+10°)=180°-75°
or, (2x+10°)=105°
or, 2x=105°-10°
or,2x=95°
or, x= 95÷2
therefore, x=47.5°
Answer:
x=21.25
Step-by-step explanation:
The lower two angles will be equal in an isosceles triangle and all angles in a triangle add up to 180 degrees so:
75+(2x+10)+(2x+10)=180
75+4x+20=180
4x=85
x=21.25
(both lower angles=52.5 degrees)
Proof:
52.5+52.5+75=180

Answer:
Are there two you're asking for?
#2: x ≥ 9
#3: x > -2
Step-by-step explanation:
#2 Work:
x - 13 ≥ -4
Step 1: Add 13 to both sides
x - 13 + 13 ≥ -4 + 13
Add -4 and 13 to get 9.
x ≥ 9
#3 Work:
x/2 > -1
Multiply both sides by 2. Since 2 is positive, the inequality direction remains the same
x/2 * 2 > -1 * 2
x > -2

point j (-8 -12) is reflected over the x axis where is j
Answer:
J(0,2)
Step-by-step explanation:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.
The new coordinate of the point j' will be (-8, 12).
What is a transformation of a point?A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.
It is the image of the point which is located in the opposite direction of a given point.
Point j (-8, -12) is reflected over the x-axis. Then the coordinate of the reflected point j' will be
If the coordinate of a point is (x, y) and it is reflected across the x-axis. Then the coordinate of the reflected point will be (x, -y).
Then the new coordinate of the point j' will be (-8, 12).

Answer:
Its A. g = 11
Step-by-step explanation:
Follow PEMDAS (Parantheses, exponents, multiplication, division, addition, and subtraction)
(g = 11 - 9 = 2)
7(2) = 14
14 + 12 = 26
I hope this helps u! :D
9514 1404 393
Answer:
(A) g = 11
Step-by-step explanation:
We can find out by undoing what is done to g.
26 = 7(g -9) +12
14 = 7(g -9) . . . . . . . . subtract 12
2 = g -9 . . . . . . . . . divide by 7
11 = g . . . . . . . . . . add 9
The value of g that makes the equation true is g = 11.
A pizzeria uses a 3-pound bag of cheese to make 8 pizzas. Use the given ratio to compute the number of pizzas the pizzeria can make with each number of pounds of cheese.
Answer:
18 pounds = 48 pizzas
18 pounds = 48 pizzas 22.5 pounds = 60 pizzas
18 pounds = 48 pizzas 22.5 pounds = 60 pizzas 27 pounds = 72 pizzas
Step-by-step explanation:
1) because they are ratios you multiply 18 and 8 (18 × 8 = 144) then you divide 144 by 3 (144÷3 =48)
2) now you do the same thing multiply 22.5 and 48 (22.5 × 48= 1,080) and divide 1,080 by 18 (1,080 ÷ 18= 60)
3) multiply 27 times 60 (27 × 60= 1,620) now divide 1,620 by 22.5 (1,620 ÷ 22.5= 72)
The table is:
Cheese Number of Pizzas
3 pounds 8
18 pounds 48
22.5 pounds 60
27 pounds 72
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
3 pounds bag of cheese makes 8 pizzas.
This means,
3 pounds = 8 pizzas
1 pound = 8/3 pizzas
Now,
1 pound = 8/3 pizzas
Multiply 18 on both sides.
18 pounds = 18 x 8/3
18 pounds = 48 pizzas
1 pound = 8/3 pizzas
Multiply 22.5 on both sides.
22.5 pounds = 22.5 x 8/3
22.5 pounds = 60 pizzas
1 pound = 8/3 pizzas
Multiply 27 on both sides.
27 pounds = 27 x 8/3
27 pounds = 72 pizzas
Thus,
The number of Pizzas for 3 pounds is 8.
The number of Pizzas for 18 pounds is 48.
The number of Pizzas for 22.5 pounds is 60.
The number of Pizzas for 27 pounds is 71.

What is the mass of 65 cm3 of water? The density of water is 1.00 g/cm3. (THE TEACHER JUST ASKED ME THIS ANSWER QUICK PLS LOL)
helps help and explain it too me im just not getting it :)
Answer:
H
Step-by-step explanation:
The answer is H because when is says JKLM is similar to PQRS it is say that the sides JK is equal to PQ, that the side KL is equal to the side QR, that the side LM is equal to RS and the side MJ is equal to SP. When trying to use proportions to find out if a figure is similar to another figure you have to divide a side that is congruent to another side length. For example side QR is congruent to side KL and side PS is congruent to the side JM so if you were to QR/KL it would be equal to PS/JM because the figures are similar if that makes sense. ( sorry if this doesn't make sense it's hard to explain this concept virtually.)
