Answer:

B) 243 km^3

Step-by-step explanation:

The formula for volume is Length x width x height, so we must find those values. By looking at the shape, the length is 9 km, width is 9 km, and height is 3 km, and after substituting these values in the equation, we get 9 km x 9 km x 3 km. When multiplied, it equals to 243 km^3, so the answer for the volume of the solid is B) 243 km^3.

Hope this helped somewhat! :P

What is the value of x in the triangle?<br><br> A: 289<br> B: 17<br> C: 15<br> D: 14.2

Maksim231197 [3]

Should be 14.2

Because if you square root 514 you get 22.6 then you do 15x15 and you get 225 then you subtract 225-22.6 and you get 14.2

HELP PLS I NEED TO TURN IT IN MONDAY!

Terri can swim 3 laps in 2.5 minutes. To find how long it takes to swim 20 laps, you can make a proportion.

$\frac{Lap}{Time}$

Put the amount of laps on the top and the time(minutes) at the bottom.

$\frac{3}{2.5} = \frac{20}{x}$

Cross multiply:

$20 \times 2.5 = 50$

Divide by 3:

$50 \div 3 = 16 \frac{2}{3} \rightarrow 16.67$

It would take Terri $16 \frac{2}{3}$ OR $16.67$ minutes to run 20 laps.

Rani has 160 DVDs 35 % of her DVDs are thrillers . 2/5 of her DVDs are comedies . The rest of her DVDs are science fiction . How

Tamiku [17]

Answer: 40

Step-by-step explanation:

Number of DVDs = 160

Thrillers = 35%

Comedies = 2/5 = 40%

Science fiction = 100 - (35 + 40) = 100 - 75 = 25%

The number of science fiction DVDs that Rani has will be:

= 25% × 160

= 25/100 × 160

= 40
