Answer:
8% increase
Step-by-step explanation:
In this question, we are asked to calculate the percentage increase that a certain increment will give over a period of 10 years.
Let the increment be x
Mathematically from the question, we can obtain that ;
(1+x)^10 = (1+1.2)
(1+x)^10 = 2.2
1+ x = 2.2^1/10
1+x = 1.082
x = 1.082 - 1
x = 0.082
This means that x = 8.2% which is approximately 8%
White paint is $17.50 per gallon so 3 1/2 gallons would be
17.50 * 3.5 = 61.25
And then blue paint is $19 per gallon so 1 3/4 gallons would be
19 * 1.75 = 33.25
Now add
61.25 + 33.25 = 94.5
The total cost would be $94.50
Not all triangles have right angles. A triangle is simply a closed figure with three sides and three angles, the sum of the degrees of which add up to 180°.
For instance, an equilateral triangle will will have all three angles equal to each other (60°, 60°, 60<span>°).
Some triangles may have right angles (90</span><span>°), but not all do.

To solve the equation, divide by 4 on both sides to isolate the variable:
4x = 30
4x/4 = 30/4
x = 7.5
