What is the volume of this pyramid? 945 cm³ 1260 cm³ 1890 cm³ 2520 cm³ A pyramid with a right triangular base. The right triangu

notsponge [240]

Answer:

The volume of the pyramid is $1,260\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the triangular pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the triangular base

H is the height of the pyramid

step 1

Find the area of the base B

$B=\frac{1}{2}bh$

we have

$b=14\ cm$

$h=18\ cm$

substitute

$B=\frac{1}{2}(14)(18)=126\ cm^{2}$

step 2

Find the volume

we have

$B=126\ cm^{2}$

$H=30\ cm$

substitute

$V=\frac{1}{3}BH$

$V=\frac{1}{3}(126)(30)=1,260\ cm^{3}$

Addie walked 2 1 2 miles in 45 minutes. Suzie covered 2 2 5 miles in 2 3 of an hour. Which girl walked faster? By how much?

kobusy [5.1K]

Answer:

Suzie walks faster by 0.27 miles per hour.

Step-by-step explanation:

Addie walked $2\frac{1}{2}$ miles in 45 minutes and Suzie covered $2\frac{2}{5}$ miles in $\frac{2}{3}$ of an hour.

So, Addie walked 2.5 miles in 45 minutes i.e. $\frac{45}{60} = 0.75$ hours.

Therefore, the walking speed of Addie is $\frac{2.5}{0.75} = 3.33$ miles per hour.

Again, Suzie covered $2\frac{2}{5}$ i.e. 2.4 miles in $\frac{2}{3}$ i.e. 0.67 hours.

So, the walking speed of Suzie is $\frac{2.4}{0.67} = 3.6$ miles per hour.

Hence, Suzie walks faster by (3.6 - 3.33) = 0.27 miles per hour. (Answer)
