500 people are asked to name their favorite color. The results of this survey are shown in the pie chart below:


Each sector of the pie chart makes an angle at the center. For example, the yellow sector makes an 18-degree angle, since 18 degrees is 5% of 360 degrees.

Which sector makes an angle closest to 40 degrees (Your answer should be a color word.)

Answers

The answer would be the Blue sector.

Because 15% of 360° is 37.2

37.2 is only 2.8 away from 40 making it the closest!

Answer:

Purple

Step-by-step explanation:

40° is one-ninth of 360°. As a percent, this is equal to

1/9 ∙ 100% = 11.111111111111111111111111111111111111111111111111...%

Answer:

I only know the first 1 sorry but here is the answer y=-3/4+2

Step-by-step explanation:

3x+4y=8

-3x      -3x subtract -3x to get on the right side

4y=-3x+8

/4     /4    /4 divide by 4 on both sides

y=-3/4x+2 since 4 can't go into 3 you leave as a fraction -3/4x

UPDATE: I found the answer to number 4

The answer is y=-11/7x+8

-11x-7y=-56

+11x       +11x Add 11x

-7y=11x-56

/-7   /-7  /-7 Divide by -7 on both sides

y=-11/7x+8 Since -7 can't go into 11 you leave as a fraction -11/7x

ANOTHER UPDATE: I found the answer to number 7

-14x+y=7

+14x     +14x Add 14x to both sides

y=14x+7 Since y doesn't have a number your answer is as shown

Answer:

I hope this helps. If I misunderstood the question let me know

Step-by-step explanation:

1. When dividing a negative by a negative, your answer would be positive.

2. When dividing a negative by a positive, your answer will be negative.

3. When dividing a positive by a negative,your answer will be negative.

Answer:

Divide like you normally would, the result will be the same as positive-number-quotients, but the quotient will be negative.

Example:

10 ÷ -5

since 5 is the dividend, 5 goes into 10 two times but note that it's negative two because of the negative division logic.

Write an equation that represents the situation.

Answers

the answer is 3 times q + 7 = 40 because there are 4 sides and 3 of the sides are equal as one of them is 7 so you add 7 to the total amount after multiplying q three times
Q = 11. 3q + 7 = 40. Since the q sides are the same length and the total perimeter is 40, you use the equation and get 11.
