One of the skylights on the roof of Bianca’s building is in the shape of the solid below.

luda_lava [24]

Answer:

588 sq. in.

Step-by-step explanation:

The total volume of air inside the skylight is in the shape of a pyramid, not the rectangular prism at the bottom.

So, if we look at the pyramid, it has a square base with dimensions 14 x 14. Its height is 11 - 2 = 9.

Formula for volume of a pyramid is:

V = 1/3 * Area of Base * height

Area of Base (since it is a square) = 14 * 14 = 196

Height is 9

plugging into the formula, we get:

$V=\frac{1}{3}*BaseArea*height\\=\frac{1}{3}*196*9\\=588$

Hence, volume is 588 sq. in.

Water evaporates from a pond at aa rate of 0.005 inches per hour. What is the change in the water level of the pond after 24 hou

Eduardwww [97]

Answer:

Water level after 24 hours will be $\frac{3}{25}\ inches$ .

Step-by-step explanation:

Given:

Evaporate rate of water= 0.005 inches per hour.

We need to find the level of water after 24 hours.

now we know the in 1 hour the water evaporates from a pool at a rate of 0.005 inches.

So To find the water level after 24 hrs we will multiply the evaporation rate with total number of hours which is 24 and the divide by 1 hour we get.

Framing in equation form we get;

water level after 24 hrs = $\frac{24 \times 0.005}1 = 0.12\ inches$

Now to convert the number in rational form we have to multiply and divide the number by 100 we get;

$\frac{0.12\times 100}{100} = \frac{12}{100}=\frac{3}{25}\ inches$

Hence Water level after 24 hours will be $\frac{3}{25}\ inches$ .

(12) (13) Geometry Check Ans 12) x = 5 y = 2 13 x = 12 y = 13/3

brilliants [131]

Problem 12)

You are correct. You solve the system
x+1 = 3y
3x-4 = 5y+1
for x and y to find that x = 5 and y = 2

As a check
x+1 = 3y
5+1 = 3*2
6 = 6 ... true equation
and
3x-4 = 5y+1
3*5-4 = 5*2+1
11 = 11 ... true equation
Both equations are true when (x,y) = (5,2) so the answer is confirmed
