Answer:
30.4 feet.
Step-by-step explanation:
We have been given the length of the ramp on the blueprint is 7.6 inches. The scale on the blueprint is 1 inch to 4 feet. We are asked to find the actual length of the ramp.
We will use proportions to solve our given problem as:
Now, we will substitute the scale length of ramp in our proportion as:
Therefore, the actual length of the ramp would be 30.4 feet.
We are given: Degrees Celsius and degrees Fahrenheit are related by formula
To find : Solve formula for F in terms of C.
Solution: We have ,
First we need to get rid 9 from right denominator.
In order to get rid 9 from right denominator, we need to multiply equation both sides by 9.
9C = 5 (F-32).
Distributing 5 on right side over (F-32), we get 5*F - 5*32 = 5F - 160.
9C = 5F - 160.
Adding 160 on both sides,
9C+160 = 5F - 160+160.
9C+160 =5F
Dividing both sides by 5, we get
(9C+160)/5 =5F/5.
Splitting fraction 1/5, we get
.
the numbers are 3 and 18
let the first number be n then the second number = 6n and the sum
sum = n + 6n = 21 thus
7n = 21
divide both sides of the equation by 7
n = = 3
the numbers are 3 and 6 × 3 = 18 → (3 + 18 = 21)
