B. 20 shirts cost $160
C. 20,160 shirts cost money
D. The total cost of shirts is 20,160

Answers

Answer:

option B is correct option.

Step-by-step explanation:

Explain what the point (20,160) represents in the context of the situation? Check all boxes that apply

Looking at the graph we come to know that 20 shirts cost $160 because x -axis represent number of shirts and y-axis represent Total Cost

So, the point(20,160) means x = 20 and y=160

We have 20 shirts and the cost is $160

So, option B is correct option.

What Are The Options?

Step-by-step explanation:

Answer:

0.42

Step-by-step explanation:

P (penny) = 1/4

P (dime) = 1/3

since the only other possibility is to pick a nickel, hence

Find the area and perimeter of the shaded region. Stuck on this one can someone help me

Answers

Answer:

perimeter-

perimeter outer rectangle = 2 (l+b)

=2×8+9

= 2×17

2×17 =34 cm sq.

perimeter of inner rectangle = 2 (l+b)

= 2×5+3

=2× 8

= 16 cm sq.

perimeter of shaded portion= 34 - 16

= 18 cm sq.

area-

area of inner rectangle =l×b

l×b = 3×5

3×5=15

15 cm sq.

area of outer rectangle =l×b

l×b= 9×8

9×8= 72

72 cm sq.

area of shaded portion = 72 -15 =57 cm sq.

hey there! In second method i have done first area of inner rectangle but you have to do first area of outer rectangle...

hope it helps you....

Answer:

Let A1 = be the large rectangle and A2 the small rectangle

=> Area A1: S1 = a1.b1 => S1 = 8 x 9 = 72m2

=> Area A2: S2 = a2.b2 => S2 = 3 x 5 = 15 m2

=> Area of the remaining surrounding square: S1-S2 = 72-15 = 67m2

=> Perimeter A1: P1 = 2 (a1 + b1) = 2 (9 + 8) = 34m

=> Perimeter A2: P2 = 2 (a2 + b2) = 2 (3 + 5) = 16m

=> Perimeter of the surrounding square: P1-P2 = 34-16 = 18m

Answer: (-2,1) is the coordinate if rotated 270 degrees from origin.

Step-by-step explanation:

Answer:

A' = (-1,2)

Step-by-step explanation:

The other person is in fact incorrect. The reason why he/she is incorrect is because, it says "rotation about the origin." which means that is flips around the middle. 90 degree rotation would be (1,-2), a 180 degree rotation would be (-2,1), a 270 rotation would be (-1,2).

Therefore, your answer would be A' = (-1, 2)

b=40 I just took this quiz

Answer:b=40 a=100

Step-by-step explanato a line is 180 degrees, the outside of the triangle is 140 degrees so the inside must be 40 to make 180 and a is also 40 because the triangles sides are the same

 

to find a we now know that both angles on the bottom 40+40 will add up to 80 and to make a complete triangle we need 180 so the measure of a is 100 degrees

a=100

b=40
