Answer: -3.3°F

Step-by-step explanation:

In integers , we represent fall in quantity by negative numbers.

Since, the temperature at noon was 16.8°F . By dropping it by 20.1°F means there is a - 20.1°F change in the temperature.

Then, the temperature at midnight = 16.8°F + (- 20.1°F)

= 16.8°F - 20.1°F

= -3.3°F

Hence, The temperature at midnight was -3.3°F .

What are the parallel sides of a trapezoid

saul85 [17]

Answer:

Parallel means that the lines will never cross. If we look at a traditional trapezoid, the top side and the bottom side are straight lines that will never cross one another. The left and right sides are slanted towards one another, to they are not parallel.

Viefleur [7K]

Answer:

16 crates

Step-by-step explanation:

-This is a division problem.

-Let x be the number of crates that will fit in to the box car.

-To solve x, we divide the volume of the boxcar by the volume of one crate:

$V=lwh\\\\l=length\\w=width\\h=height\\\\V_{bc}=20m\times 3m\times 4m\\\\=240\ m^3\\\\V_c=lwh\\\\=5m\times1.5m\times 2m\\\\=15\ m^3\\\\\therefore x=\frac{V_{bc}}{V_c}\\\\=\frac{240}{15}\\\\=16\ crates$

Hence, 16 crates will fit in the boxcar.
