Let's assume the question is to find the area of the shaded region.

7. We have to assume the bottom right angle is right as well.

Consider the white triangle at the bottom; call its left leg x.

Then the big tra pezoid which includes the shaded part has area

(1/2)((14 + x) + 26)(15)

and the bottom right triangle has area

(1/2)x(15)

and white triangle on the right has

(1/2)(26)(15 - 6)

The total area of the shared part is thus

(1/2)((14 + x) + 26)(15) - (1/2)x(15) - (1/2)(26)(15 - 6)

= (1/2)(15)(40 + x - x) - 13(9)

= 183

Answer: 183 sq in

8. That's an annulus, the difference between two circles.  The outer one has radius 21/2 m, the inner one radius 21/2 - 3.5.

A = πR²-πr² = π( (21/2)² - (21/2 - 3.5)² ) = π(2(21/2)(3.5) - 3.5²) = 3.5π(21-3.5)=61.25π

Answer: 61.25π sq m

9. That looks like a parallelogram less a right triangle.

The parallelogram has area 15(23.8)

The right triangle missing leg x satisfies

x² + 21² = 23.8²

x = 11.2

The right triangle area is

(1/2) (21)(11.2)

So the shaded area is

15(23.8) - (1/2) (21)(11.2) =239.4

Answer: 239.4 sq ft

10.  That's a circle less a square.  The diagonal of the square is 8√2 and the radius of the square is half of that, 4√2

The area is

π(4√2)² - 8² = 32 π - 64

Answer: 32π - 64 sq cm

Select the term that does not describe the triangle. Select all that apply.
bija089 [108]
It has a right angle (90 degrees) and 2 sides are equal which makes it isosceles.
So there's only one choice left.

20. A shoe store owner had an employee record the shoe sizes purchased by customers during one hour on two different days. The
Ulleksa [173]

Answer:

The correct option is C. 9

Step-by-step explanation:

From the graphs shown in the attached file we can see that the maximum number of shoes bought were of size 9. On both days the number of size 9 shoes bought was 5 which was the highest number of shoes bought for any size shoe. Therefore since size 9 sell the most on both days the owner should stock most of size 9 shoes in the store's inventory.

This table represents the number of inches, n, a plant grows after m, months in a new pot.
Yuki888 [10]

Answer: Slope = 5/4

y-intercept = 2

Step-by-step explanation:

We have the table:

Months, m            Plant height in inches, n

0                           2

2                           4.5

4                            7

6                            9.5

We want a linear relationship to represent this table.

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

In this case we can select any pair of points, for example, i will choose the first two:

(0, 2) and (2, 4.5)

Then the slope is:

a = (4.5 - 2)/(2 - 0) = (2.5/2) = 1.25 = 5/4

Then our line can be written as:

y = (5/4)*x + b

To find the value of b, we can replace the values of any of the points in the equation, for example, i will use the point (0, 2) or x = 0, y = 2.

2 = (5/4)*0 + b

2 = b

Then our equation is:

y = (5/4)*x + 2.

Slope = 5/4

y-intercept = 2
