You have to find 70% of 80 First to figure out the Percentage.
70= 80*x / 100, 7000/80 =x, x = 700/8 = 87.5%. Therefore, your answer would be 87.5%.

Svetllana [295]
In this item, it is assumed that since the pattern is cut out of the paper which is usually a rectangle then, the shape of the pattern is also rectangle. The perimeter of the rectangle is,

           P = 2L + 2W

The area is equal to,
              Area = L x W

If we assume that length and width are equal, in order to maximize the space. 
              1600 cm² = L x L

The value of L from the equation is 40 cm.

Find the area of the isosceles triangle.
kogti [31]

Answer:

The hight length : h

The base length : a

Apply the Pythagorean theorem in the right triangle :

h² = 13² - (10/2) = 144

h  = √144 = 12 cm

S = (a x h)/ 2 = ( 10 x 12 )/2 = 60 cm²

The slope of the linear equation is 20 and the y-intercept is 150

<h3>What is a Slope?</h3>

Slope measures how steep a straight line is. It is described as rise over run.

The slope of the linear equation can be found as follows;

He opens the account with $150 and he plans to save $20 each week. Therefore,

let

x = number of weeks

Therefore,

  • y = 20x + 150

where

y = amount in his account after x number of weeks.

Using the slope intercept equation,

<h3>Slope intercept equation:</h3>
  • y =mx + c

where

m = slope

c = y-intercept

Therefore, the slope of the linear equation is 20 and the y-intercept is 150
