Answer:
21 G = 390miles
G = 390/21
G = 18.57
gallons of gas should he expect to use to travel 635 miles to Daytona Beach
= 635/18.57
=34.19
<em><u>Hence,</u></em><em><u> </u></em><em><u>3</u></em><em><u>4</u></em><em><u> </u></em><em><u>gallons </u></em><em><u>is </u></em><em><u>the </u></em><em><u>correct</u></em><em><u> answer</u></em>
Answer:
Step-by-step explanation:
Time is the independent variable here. The tank is being filled and the amount of water in it is dependent on how much time passes by.
This is a straight line function (linear function); the rate at which the tank is filled is:
750 m^3

Answer:
25.5 sq cm
Step-by-step explanation:
1*3/2+7*3+1/2*3*2=3/2+21+3=25.5 sq cm
The value of c is 
Explanation:
Given that the trinomial is 
We need to determine the value of c such that the trinomial is a perfect square.
The value of c can be determined using the formula,
From the trinomial, the value of b is given by
Substituting the value of b in the above formula, we have,
Squaring both the numerator and denominator, we have,
Thus, the value of c is which makes the trinomial a perfect square.
Answer:
6 feet tall.
Step-by-step explanation:
The boy is 4 ft tall, but he casts a 6 ft long shadow. You need to find how long a shadow would be if a person/thing was just 1 ft tall.
To do this, you would need to divide 4 by 4, and 6 by 4 as well.
6/4 is 1.5, or 1 and a half.
If a person (or a thing) is 1 foot tall, the statue will cast 1 and a half feet long shadow.
The statue casts a 9 ft long shadow.
Since we already figured out 1 ft = 1 and 1/2 ft shadow, and since the statue casts a 9 foot long shadow, you need to divide 9 by 1.5.
(You'll get 6.)
This means that the statue is 6 feet tall, and it casts a 9 foot long shadow.
