Step-by-step explanation:
As it is said that the triangles are similar so the ratio of the corresponding sides are equal so
AB / ED = BC / EF
x² / 18 = 7 / 14
x² / 18 = 1 / 2
2x² = 18
x² = 18 / 2
x² = 9
x² =( + 3)²
Therefore
x = 3 or x = - 3

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
Answers
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

1 pizza costs $0.50 to make. They sell it for $12. Find the percent markup.
Answers
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%.

If the area of a square is increased by 69%, then the side of the square is increased by what percent?
Answers
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%

We can write a system to solve this problem
Let x= the radius of Circle A
Let y=the diameter of Circle B
x=2y-3
2x+y=49
since we are trying to find the area and the circumference of circle A, we only have to find what x is
x=2y-3 → y=1/2x+3/2
next, we plug in 1/2x+3/2 for y:
2x+1/2x+3/2=49
we can then multiply all the numbers by 2 to get rid of the fractions:
4x+x+3=98
5x+3=98
5x=95
x=19
Circle A radius=19ft
Finally, we solve for the area and circumference:
Area:
A=pi*r^2
A=3.14*19^2
A=1133.54 feet^2
Circumference:
C=2*pi*r
C=2*3.14*19
C=119.32 feet

Find the approximate radius a circle if its circumference is 37.68 inches. Use (pie symbol)= 3.14.
Answers
Answer:
radius = 6 inches
Step-by-step explanation:
37.68/3.14 = 12 = diameter
radius = 12/2 = 6 inches
C = 2 pi r
r = C / 2 pi
r = 37.68 / (2 * 314)
r = 6
Area of a circle:
A = pi r^2
A = 3.14 * 6^2
A = 113.04
Answer:
The area of the circle is 113.04 square units
