Answer:
=64 %
Step-by-step explanation:
The percentage decrease is found by
Percent decrease = (original - new)/ original * 100 percent
The original price is 25
The new price is 9
Percent decrease = (25-9)/25 * 100%
=16/25 * 100%
=64 %
Answer:
Step-by-step explanation:
Formula (Normal Area Trapezoid)
A = (b1 + b2 ) * h / 2
Formula (Trapezoid Modified for the question)
b1 + b2 is given as 90
Area = 90*h / 2
Givens
b1 + b2 = 90
Area = 1170
h = ?
Solution
Area = 90 * h / 2 Substitute the givens into the formula
1170 = 90 * h/ 2 Divide by 2 on the right.
1170 = 45 * h Divide both sides by 45
1170 / 45 = 45 * h/45

<em>Answer: h = 45 inches.</em>
When they ask for the difference they are asking to subtract them. In this case we need to find out how many pieces of candy she was off by
lets do the math:)
4,182 - 3,498 = 684
this means that Jessica's guess was off by 684 pieces of candy.
your answer? 684
MARK AS BRIANLIEST! thanks:)
By using what we know about polynomials, we will see that the missing side measures 8x - 1
<h3 /><h3>How to get the perimeter of a triangle?</h3>
The perimeter of a triangle is just the sum of its 3 sides, in the image the two known sides are: 3x - 5 and x + 2, and the missing side measures p(x).
Then we will have that the perimeter is the sum of these 3 lengths:
13x - 4 = 3x - 5 + 2x + 2 + p(x)
13x - 4 = 5x - 3 + p(x)
Now we can assume that p(x) is also a linear polynomial, so:
p(x) = a*x + b
Then we have:
13x - 4 = 5x - 3 + a*x + b
This means that:
5 + a = 13
-3 + b = -4
Solving these we get:
a = 13 - 5 = 8
b = -4 + 3 = -1
This means that the missing length is:
p(x) = 8x - 1
