1. Determine the variables in the figure below.<br> 20<br> 50

Marina CMI [18]

Answer:

r=8

t=4√29

Step-by-step explanation:

By the altitude leg theorem:

${20}^{2} = 50r$

This implies that:

$r = \frac{20 \times 20}{50}$

We simplify to obtain:

$r = 4 \times 2 = 8$

By the Pythagoras theorem:

${t}^{2} = {20}^{2} + {8}^{2}$

${t}^{2} = 400 + 64$

${t}^{2} = 464$

$t = \sqrt{464}$

$t = 4 \sqrt{29}$

Your new dresser will be 2/5ths larger than your old dresser. Your old dresser can hold 6.25 cubic feet, how much cubic feet wil

marissa [1.9K]

Answer:

8.75 cubic feet

Step-by-step explanation:

Your new dresser will be $\frac{2}{5}^{ths}$ larger than your old dresser.

This means that your new dresser wil be

$1+\dfrac{2}{5}=\dfrac{5+2}{5}=\dfrac{7}{5}$

of your old dresser.

Your old dresser can hold 6.25 cubic feet, so your new dresser can hold

$\dfrac{7}{5}\cdot 6.25=7\cdot 1.25=8.75\ ft^3$
