Answers

Answer 1

Answer:

y = 7/50

Step-by-step explanation:

-5y + 56y - 32 = -7 - 18 + y

50y = -25 + 32

50y = 7

y = 7/50

Answer 2

Answer:

[tex] \frac{1}{2} [/tex]

Step-by-step explanation:

Open the bracket

[tex] - 5y + 56y - 32 = 7 - 18 + 9y[/tex]Collect the like terms

[tex]51y - 9y = - 11 + 32[/tex]

[tex]42y = 21[/tex]

Divide both sides by 42

[tex]y = \frac{21}{42} [/tex]

[tex]y = \frac{1}{2} [/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​

Answers

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!

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?

Answers

Answer:

the percentage increase for bread and cake is 66.67% and 20% respectively

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

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!!♥️

Answers

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.

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.

Answers

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]
