Answer:

4. The relationship is proportional because, for every 12 students, there is one chaperone and when you multiply 12 by the number of chaperones you get the same numbers that the table shows.

1. the relationship is proportional.

45/1= 45

45/2 = 90

45/3 = 135

45/3 = 180

2. the constant of 2 is 10. the constant of 3 is 2.

the relationship between x and y is that x divided by y equals the constant.

4. x divided by y equals the constant, or

x÷y=c(constant)

hope that helps and sorry for taking so long

Answer:

D = .44P

Step-by-step explanation:

We need to find the slope of the line

m = (y2-y1)/ (x2-x1)

Using two points

m = (22-4.4) /(50-10)

= 17.6/40

= .44 lb/ in^2 ft

We can use the point slope form of the equation

y-y1 = m(x-x1) where y=D and x=P

D-4.4 = .44 (P-10)

Distribute

D-4.4 = .44P - 4.4

Add 4.4 to each side

D -4.4+4.4 = .44P -4.4+4.4

D = .44P

Doug estimates that his soccer team will win 7 games this year. The team actually wins 10 games. What is the percent error of Do

baherus [9]

Answer: 30%

Step-by-step explanation:

Percent error = $\dfrac{|\text{Estimated value - Actual value}|}{\text{Actual value}}\times100\%$

Estimated number of games win this year = 7

Actual number of games won = 10

Now , the percent error of Doug’s estimate = $\dfrac{|7-10|}{10}\times100\%= \dfrac{3}{1}\times10\%=30\%$

Hence, the percent error of Doug’s estimate = 30%

Solve for a. 1/3(21-3a)=6-a

OverLord2011 [107]

Answer:

no solution

Step-by-step explanation:

Given

$\frac{1}{3}$ (21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )

21 - 3a = 18 - 3a ( subtract 21 from both sides )

- 3a = - 3 - 3a ( add 3a to both sides )

0 = - 3 ← not possible

This indicates the equation has no solution
