Answer:
Check pdf
Step-by-step explanation:
Answer:
4ft
Step-by-step explanation:
circumference of circle = π r^2
=> circumference = 50.25 ft

[tex] \sqrt{ {4 a}^{2} + {12a}^{2} } [/tex]
Answer:
The answer is 4a
Step-by-step explanation:
1) Simplify 4a² + 12a² to 16a².
[tex] \sqrt{ {16a}^{2} } [/tex]
2) Use this rule:
[tex] \sqrt{ab} = \sqrt{a} \sqrt{b} [/tex]

A block of marble is in the shape of a rectangular prism. The block is 2 feet long. 3 feet wide, and 90 inches high. What is the volume of the block? The volume of the block is cubic feet
Answer:
Volume of a rectangular prism can be found with the equation
v = length × width × height
They are trying to trip you up a little bit here because they give 2 measurements in feet then the last in inches. So for your prism...
18 inches = 1.5 ft
v = l×w×h
v = 3×2×1.5
v = 9 ft^3
Volume=length*width*height, so first you would have to change the units of the inches to feet, which would be 90/12=7.5, so now you can fit that into the equation, 2*3*7.5=45 ft cubed!

Answer:
1) x = 42 ; y = 42
2) x = 72 ; y = 48 ; z = 60
Step-by-step explanation:
1)
x + 42 + 96 = 180
x + 138 = 180
x = 42
y + 42 + 96 = 180
y + 138 = 180
y = 42
2)
x + 108 = 180
x = 72
y + 132 = 180
y = 48
z + x + y = 180
z + 72 + 48 = 180
z + 120 = 180
z = 60

Mrs. Anderson's closet consists of two sections, each shaped like a rectangular prism. She plans to buy mothballs to keep the moths away. She needs one box for every 16 cubic feet of space. How many boxes should she buy? Explain how you found the answer.
Answer:
13 boxes
Step-by-step explanation:
Given
See attachment for closet
Required
Determine the number of boxes needed to fill the closet
First, we calculate the volume of the two section.
[tex]Volume = Width * Length * Height[/tex]
From the attachment
The first section is:
[tex]Width = 5ft\\ Length = 4ft\\ Height = 8ft[/tex]
[tex]V_1 = 5ft * 4ft * 8ft[/tex]
[tex]V_1 = 160ft^3[/tex]
The second section:
[tex]Width = 3ft\\ Length = 2ft\\ Height = 8ft[/tex]
The width is the last label at the top
The length is the difference between the length of the first section (4ft) from the total length of the closet (6ft) i.e. 6ft - 4ft
The volume is:
[tex]V_2 = 3ft * 2ft * 8ft[/tex]
[tex]V_2 = 48ft^3[/tex]
Total volume (V) is:
[tex]V = V_1 + V_2[/tex]
[tex]V = 160ft^3 + 48ft^3[/tex]
[tex]V = 208ft^3[/tex]
The number of box (n) needed is then calculated by dividing the calculated volume of the closet by the volume of each box
[tex]n = \frac{208ft^3}{16ft^3}[/tex]
[tex]n = 13[/tex]
Paula, the local baker, usually makes 1"5 loaves of bread and 10 cakes per day, but today she made 25 loaves of bread and 12 cakes. What is the percent increase far each bakery item?
Answer:
the percentage increase for bread and cake is 66.67% and 20% respectively
Step-by-step explanation:
The computation of the percentage increase for each bakery item is shown below:
For bread
= (25 - 15) ÷ 15
= 66.67%
For cakes
= (12 - 10) ÷ (10)
= 20%
Hence, the percentage increase for bread and cake is 66.67% and 20% respectively

A new amusement park presold discounted tickets for the opening day as well as upon arrival at the park the opening day ticket sales for the park including pre-sales is represented by this function where T(h) is the number of tickets sold H hours after opening at 7:00.am.
What is the approximate rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m?
HELP PLEASE I WILL MARK BRAINLIEST!!♥️
Answer:
-21 tickets per hour
Step-by-step explanation:
I think it's right
Answer:
Therefore, the correct answer is option C. 21 tickets per hour.
Step-by-step explanation:
Given: the opening day ticket sales for the park is given by the function[tex]T(h)=\frac{386+110h}{h}[/tex] where [tex]T(h)[/tex] represents the number of tickets sold [tex]h[/tex] hours after opening at 7:00 a.m.
To find: the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m.
For 10 a.m., [tex]h=3[/tex]
So the number of tickets sold upto 10 a.m. are,
[tex]T(3)=\frac{386+110 (3)}{3}[/tex]
[tex]T(3)=238.67[/tex]
Similarly, for 1 p.m., [tex]h=6[/tex] hours
So, the number of tickets sold in 6 hours are,
[tex]T(6)=\frac{386+110(6)}{6}[/tex]
[tex]T(6)=174.33[/tex]
Now, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is,
[tex]\frac{T(6)-T(3)}{6-3}[/tex]
[tex]=\frac{174.33-238.67}{3}[/tex]
[tex]=-21.445[/tex]
which is approximately [tex]-21[/tex] tickets per hour.
Hence, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is -21 tickets per hour.
The correct answer is option C.
