Aneli [31]3 years ago

Answer:

x = 12

Step-by-step explanation:

Quadrilaterals ABCD and FECG are similar, so their corresponding sides would be in the proportion.

\frac{x}{6}  =  \frac{5 + 5}{5}  \\  \\  \frac{x}{6}  =  \frac{10}{5}  \\  \\  x =  \frac{10 \times 6}{5}  \\  \\ x = 2 \times 6 \\  \\ x = 12 \:

What is the unit rate $1.99 for 30 oz to nearest tenth
KatRina [158]

Answer:

$0.10/oz

Step-by-step explanation:

Unit rate simply means the amount per 1 unit of something.

In this case, we want to find the amount of money for 1 oz of something.

So, we divide 1.99 by 30 and divide 30 by 30 to get:

(1.99 / 30) / (30 / 30) = $0.0663 / 1 oz

Rounded to the nearest tenth, 0.0663 is about 0.1.

Thus, the answer is $0.10/oz.
