It’s quite simple. Take the total percentage of people from this- 25*2 and add 43. It’s 93%

You can add up the percentages. When doing this, I am also thinking that there are 100 residents in all.
From 600 to 649, there are 25 people or 25%.
From 650 to 699, there are ABOUT 45 people or 45% (43 people)
From 700 to 749, there are 25 people or 25%.
Let's add it up.
25+25+43
93
Letter A, 93%.

Alex wants to sew a pillow in the shape below. How many square yards of fabric are needed to sew the pillow? Fabric is only sold
r-ruslan [8.4K]

The shape is missing, so i have attached it.

Answer:

2.6

Step-by-step explanation:

From the image attached, the diameter of the inner semi - circle is 0.5 yards while the length of each side of the pillow is 0.2 yards.

Thus, for us to find the length of the seam which is along the edges of the pillow, we will calculate the perimeter of the outer semicircle, then add the perimeter of the inner semicircle and also add the sides too.

Now, due to the fact that the length of the sides of the pillow are 0.2 yards each, the diameter of the outer circle would be;

0.5 + 0.2 + 0.2 = 0.9 yards. So, the perimeter of the outer semicircle is,

P0 = πd/2 = π × 0.9/2 =0.45π yds

The perimeter of the inner semicircle would be given as;

PI = πd/2 = π × 0.5/2 =0.25π yds.

Thus, we can calculate the total perimeter of the pillow as;

PT = P0 + PI + 0.2 + 0.2

PT = 0.45π + 0.25π + 0.2 + 0.2

PT ≈ 2.6 yards

Alex will need 2.6 yds

What type of association does the graph show between x and y? (5 points)
dlinn [17]

ANSWER

Linear positive association

EXPLANATION

As the values of x are increasing, the values of y are also increasing.

We can actually find the slope of this curve to be,

m =  \frac{2 - 1}{2 - 1}  =  + 1

We can see that the slope is positive.

This indicates a linear positive association between x and y.

The correct choice is A.

goblinko [34]

Answer:

The area is multiplied by 4

Step-by-step explanation:

The area of a circle is directly proportional to its square radius so if the radius is increased by x, the area will be increased by x ^ 2
