To solve this problem, we are going to set up an equation. However, first we need to convert the percentages to decimals by dividing by 100.
15% = 0.15 , 7.5% = 0.075
Now, we should substitute in our given information into our equation and let our unknown value be equal to the variable x.
0.15(500) = 0.075x
Then, we should simplify our equation by multiplying together the two factors on the left side of the equation.
75 = 0.075x
Finally, we should divide both sides of the equation by 0.075 to get the variable x alone.
x = 1000
Therefore, your answer is 1000.
Hope this helps!
Answer:
Area of a circle- <em>pi </em>x <em>r </em>square
3.14 x 2 x 2
= 3.14 x 4
= 12.56
Round off- 13
For this case we must indicate the correct sign between the following numbers:
We have to:
So, we have to 
Answer:
14.59
To solve, simply plug -7.1 into -Z. Since Z is negative in the equation, it will turn the Z that’s given to us into a negative. Since that Z is already negative, it will now become a positive since that’s what two negatives being multiplied make. This is what your problem will look like:
-(-7.1) + 7.49
7.1 + 7.49 = 14.59
Answer: hypotenuse = 
Step-by-step explanation: Pythagorean theorem states that square of hypotenuse (h) equals the sum of squares of each side (
) of the right triangle, .i.e.:
In this question:
= 
2bc
Substituing and taking square root to find hypotenuse:
Calculating:
= 
, then:
Hypotenuse for the right-angled triangle is units
