Answer:
B. 960 units²
Step-by-step explanation:
find the area of each surface
the area for a triangle is 1/2(b×h), and there are q triangles here, so just do b×h
y×h = 24×16 = 384
next, find the area of the bottom and sides of the prism.
x×z = 20×9 = 180
180 × 2 = 360
z×y = 9×24 = 216
finally, add all of those together
384+360+216 = 960 units²
Refer to the circle to the right.
a. Find the circumference of the circle. use 3 as the estimate of π.
b. Find the circumference of the circle using 3.14 for π.
c. Another estimate of π is 3.14159. Find the circumference using this estimate.
d. What do you notice about the estimate used for π and the circumference of the circle?
Answer and explain how you got to your answer to get brainliest
Answer:
a. If π = 3 => C = 10 x 3 = 30
b. if π = 3.14 => C = 10 x 3.14 = 31.4
c. if π = 3.14159 => C = 10 x 3.14159 = 31.4159
d. using the whole number of π makes the calculation easier but using the π with more decimals will make the result more accurate.
Step-by-step explanation:
Diameter = 10 => radius = 10/2 = 5
Circumference: C = 2πr = 2π(5) = 10π
a. If π = 3 => C = 10 x 3 = 30
b. if π = 3.14 => C = 10 x 3.14 = 31.4
c. if π = 3.14159 => C = 10 x 3.14159 = 31.4159
d. using the whole number of π makes the calculation easier but using the π with more decimals will make the result more accurate.
Answer: hope this helps ♡
a. C = 3 × 10 = 30cm
b. C = 3.14 × 10 = 31.42cm
c. C = 3.14 × 10 = 31.42cm
d. The bigger the estimated value of π, the bigger the circumference. The circumference gets more accurate when you use the whole number of π.
Step-by-step explanation:
C = π ×d (or 2r) d =10
a. π = 3 C = 3 × 10 = 30cm
b. π = 3.14 C = 3.14 × 10 = 31.42cm
c. π = 3.14159 C = 3.14 × 10 = 31.42cm
d. The bigger the estimated value of π, the bigger the circumference. The circumference gets more accurate when you use the whole number of π.

A restaurant uses c cups of flour for baking rolls and 12 cups of flour for baking pies each day. Use the Distributive Property to write an expression for how much flour the restaurant uses in seven days.
B.
Simplify the expression from A using the Distributive Property.
Answer:
(7 x 12) + (c x 7)
Step-by-step explanation:
assuming c = x all I did was multiply the total cups of flour by 7 (7 days in a week. I did that both times.

-Graphing Linear equalities with slope and y-intercept-
Answer:
I don't know how to type the table but the description is:
Slope= -3/2
y-intercept=0
y-intercept would be the b in y = mx + b and in this equation, it looks like there is no b but there is, it is just an invisible 0 because you don't need to add or subtract 0. The slope is -3/2 because m in the equation y=mx+b means slope.
hope that helps!

Yvonne used 5 tablespoons of butter for a recipe. For a second recipe she used 10% less butter than she did for the first recipe. The total amount of butter, in tablespoons, she used for both recipes can be found using the expression below:
5 + 5 – 5(10%)
Which other expression can be used to find the amount of butter, in tablespoons, she used for both recipes?
A. 10 – 5%
B. 10 – 50%
C. 5 + 5(0.9)
D. 5 + 5(1 – 10)
On a coordinate plane, triangle A has points (3, 3), (6, 3), (6, 9). Triangle A prime has points (negative 2, negative 1), (negative 2, negative 2), (negative 3, negative 2).
Answer: Your welcome!
Step-by-step explanation:
Triangle A prime is a reflection of triangle A across the x-axis. A reflection across the x-axis will switch the sign of the y-coordinates, leaving the x-coordinates unchanged. This means that the x-coordinates of triangle A prime are the same as those of triangle A, but the y-coordinates are opposite in sign. For example, the y-coordinate of the first point of triangle A is 3, so the y-coordinate of the first point of triangle A prime is -1.

Answer: M = 2
Step-by-step explanation:
Combine like terms!
5m + 8m = 13m
3 + 7 +4^2 =
3 + 7 + 16 = 26
13m = 26
M = 2.
Check!
5(2) + 8(2)
= 10 + 16 = 26!
3 + 7 +4^2 =
3 + 7 + 16 = 26

If you know the area of a rectangle, can you determine its length and width? Explain.
Answer: Yes, you just need to figure out what factors into the area, the factors will be your length and width (Copy and paste this)
Step-by-step explanation:
If you know the area of a rectangle, you can determine its width and length
Example 1:
Area = 18
Figure out what factors into 18
6 x 3 = 18
W (6) x L (3) = A (18)
Example 2:
136 = A
Factors of 136 1, 2, 4, 8, 17, 34, 68, 136.
W (8) X L (17) = A (136)

You are designing a new, more extensive coral reef exhibit that will stun visitors with its size and vibrant colors.
The tank requires special glass to protect this delicate environment. The glass costs $25,000 + a 10% engineering fee + a 5% shipping fee calculated on the cost of the glass plus engineering charges.
What is the total cost of the glass, including fees?
Answer:
Total Cost = 25,000(1.10 + 0.05)
Total Cost = 25,000(1.15)
Total Cost = 28,750
The total cost of the glass including fees is $28,750.

-Graphing Linear equalities with slope and y-intercept-
The slope is equal to -2.
The y-intercept is equal to 1.
The equation is y = -2x + 1.
What is the point-slope form?Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.At point (-1, 3), an equation of this line can be calculated by using the point-slope form:
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 3 = (-1 - 3)/(1 + 1)(x + 1)
y - 3 = -2(x + 1)
y = -2x - 2 + 3
y = -2x + 1

Carissa also has a sink that is shaped like a half-sphere. The sink has a volume of 4500/3 πin3. One day, her sink clogged. She has to use one of two conical cups to scoop the water out of the sink. The sink is completely full when Carissa begins scooping.
(a) One cup has a diameter of 6 in. and a height of 14 in. How many cups of water must Carissa scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number.
(b) One cup has a diameter of 10 in. and a height of 12 in. How many cups of water must she scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number.
By taking the quotient between the volume of the sink and the volume for each cone, we will see that both of your answers are correct.
How many coops does Carissa need to scoop out in each case?
First, we know that the sink has a volume V =
(2000/3)*pi in^3
A) First, she uses a cone of a diameter of 4 in and a height of 8 in.
Remember that the volume of a cone of diameter D and height H is:
V = pi*(D/2)^2*H/3
Then this cone has a volume of:
V = (pi*/3)*(4in/2)^2*8in = (pi/3) 32 in^3
The number of scoops needed to completely remove the water out of the sink is given by the quotient between the two volumes, it is:
Rounding it, we get 63, so she needs to scoop 63 times.
B) This time the diameter is 8 in and the height 8in, so the volume of the cone is:
V" = (pi/3)*(8in/2)^2*8in = (pi/3)*128 in^3
This time, she needs to scoop:
Rounding to the next number we get 16, she needs to scoop 16 times.
So both the answers are correct :)
