If the area of a square is increased by 69%, then the side of the square is increased by what percent?
Answer:
Percent Increase in measure of the side of a square = 30%
Step-by-step explanation:
Let the measure of the side of a square = s
Area of the square = (Side)²
= s²
If the area of the square is increased by 69%
Area of the new square = s² + 69% of s²
= s² + 0.69s²
= 1.69s²
Therefore, measure of the side of the new square = √(Area of the square)
= √(1.69s²)
= 1.3s
Measure of side of the old square = s
Therefore, increase in measure of the square = 1.3s - s
= 0.3s
Percent increase in the measure of the side of the square
= [tex]\frac{\text{Increase in measure}}{\text{Measure of the side of the original square}}\times 100[/tex]
= [tex]\frac{0.3s}{s}\times 100[/tex]
= 30%

David and Almudena have between the two 225 euros. Calculate how much money each one has if Almudena has 75 euros more than David.
Answer:
Almudena has $150
David has $75
Step-by-step explanation:
First, we will deduct from the total the difference in money, so we divide by two the rest.
Total equal amount= 225 - 75
Total equal amount= 150
Between the two of them, they have $150. Now, we divide by 2:
David= 150 / 20= $75
Almudena= (150 / 2) + 75= $150
Almudena has $150
David has $75

1 pizza costs $0.50 to make. They sell it for $12. Find the percent markup.
Answer:
ok let me try this again
To explain a markup, let's use an example: Let's say you purchase a box of paper that costs one dollar. You aim for a profit of 50%. By multiplying the cost by 50%, you get $0.50. This is your markup price. Add that to the price that you paid to purchase the box of paper, and now the total is $1.50. This is the selling price of the box of paper. Therefore, your markup percentage is 50%.

The radius of each tire on a delivery truck is 11 inches. Approximately how far will the truck have traveled after 5 rotations of a tire?
Answer:
345.62in
Step-by-step explanation:
Given data
Radius=11in
The expression for the circumference is
C=2πr
C=2*3.142*11
C=69.124 in
In 1 revolution the bike will travel 69.124in
in 5 revolutions the bike will travel
=69.124*5
=345.62in
a baker makes 130 loaves so that there are 6 times as many white loaves as granary loaves. half as many brown loaves as white loaves how many of each type does he make
Answer:
Answer: 78 whites, 13 granary, 39 brown.
Step-by-step explanation:
For each 6 whites, there is 1 granary, and 3 brown. That adds up 10 loaves, so just multiply all those numbers by 13.
The Number of white, brown and granary bread loaves are ; 78, 39 and 13 respectively.
Total loaves of bread = 130
Let :
Number of granary loaves = xTherefore,
Number of white loaves = 6x Number of brown loaves = (1/2 × 6x) = 3xThis means that :
Number of white + brown + granary loaves = 130(6x + 3x + x) = 130
10x = 130
x = 130÷ 10
x = 13 loaves
Therefore,
Number of granary loaves = 13 Number of brown loaves = 3(13) = 39Number of white loaves = 6(13) = 78Learn more : https://brainly.com/question/18796573
