Divide bags of sand by gallons of water:
14 /6 = 2.33
21/9 = 2.33
The ratio is the same, so this means for every gallon of water you need 2.33 bags of sand.
Convert the fractions into decimals and you will get 7/3 = 2.33
The answer for Part 1 is D) 7/3
For part 2, multiply the gallons of water by 2.33 to get the number of sand bags needed:
12 x 2.33 = 27.99, which rounds to 28.
The answer is C) 28 bags.
It would be 2.1 hours or about 2 hours.
It says the train travels about 2118 miles per 8 miles. So, divide 2118 by 8, which gives you 264.75 (when you see the word PER it usually indicates to divide). That gives you part A.
Then, you divide 560, (which is t<span>he distance between Columbus, Ohio, and New York) by 264.75 to see how many hours it took, which gives you 2.1152030217...., which simplifies to 2.1. Which gives you the answer for B.
So,
A is 560 and
B is 2.1 or 2

Answer:
plane = 250mi/hr
wind = 5mi/minute
Step-by-step explanation:
speed = distance/time
plane = 1000miles/4hour
wind = 1000miles/200minutes
Answer:
y = -2/3x + 6
Step-by-step explanation:
The length of the mirror is 64.52 cm
<u>Explanation:</u>
Given:
Distance of the person from the mirror = 145cm
Angle of depression = 14°
Angle of elevation = 11°
Vertical dimension of the mirror = ?
For angle of elevation:
For the angle of depression:
Total length of the mirror, AC = AB + BC
= 28.275 + 36.25cm
= 64.52 cm
Therefore, the length of the mirror is 64.52 cm
