Answer: 22 minutes
Step-by-step explanation: 500-170 means that he drained 330 gallons of water so 330 divided by 15 gallons a minute so you get 22 so it takes 22 minutes to have 170 gallons left in the pool
Answer:
<h3>
28° and 152°</h3>
Step-by-step explanation:
Suplementary angles add to 180°
If one of angles is 124° more than the other then if we subtract 124° from the larger angle we get two equal angles which sum is also 124° less
180° - 124° = 56°
56° - sum of two equal angles
56° ÷ 2 = 28° - the measure of smaller angle
28° + 124° = 152° - the measure of larger angle
Answer:
To use proportions to solve ratio word problems, we need to follow these steps:
Identify the known ratio and the unknown ratio.
Set up the proportion.
Cross-multiply and solve.
Check the answer by plugging the result into the unknown ratio.
Step-by-step explanation:
length of 1 bacteria = 300 = 3 *10^2 nanometers
= 3 * 10^2 / 1 * 10^9 m
= 3 * 10^(2-9)
= 3 * 10^-7 m
It can hold 16 gallons of water
