Answer:
6. 175/125=x/100
Cross products equal 125x=17500
Solve for x and you get 140%
7. 20% of 720 is 144. You need to find 120% so add the full 720 (100%) to the 144 and you get 864 (120%)
Step-by-step explanation:
Answer:
(b)The original price of the shoes is $60.
Explanation:
Part A
In this situation:
• 15% is the PERCENT
,
• $9 is the PART
,
• The original price is the WHOLE.
Part B
If 15% is taken off, the customer will save $9.
This means that 15% of the original price = $9.
Let the original price=p
The original price of the shoes is $60.
Answer:
<em>0.5 < x < 14.5</em>
Step-by-step explanation:
<u>Triangle Inequality Theorem
</u>
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining those inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
We are given two of the triangle side lengths as y=7.5 and z=7, thus the third side length (x) can be in the range:
7.5 - 7 < x < 7.5 + 7
0.5 < x < 14.5
<u>Note: The latter is the correct answer but none of the choices is accurate. Choice D is closer to the correct answer but the endpoints cannot be included.</u>
1st find discount
18-13=5
5 is discount
discount from original
5/18=x%
percent means parts out of 100 so x%=x/100
5/18=x/100
multiply both sides by 900
250x=9
divide both sides by 250
x=27.77777
aprox 28%
answer is 28%
