Answer:

$\huge\boxed{slope=\dfrac{3}{5}=0.6}$

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (1, -1) and (6, 2).

Substitute:

$m=\dfrac{2-(-1)}{6-1}=\dfrac{2+1}{5}=\dfrac{3}{5}=0.6$

Answer:

$2,543.84 is your answer.

Step-by-step explanation:

What you do first is you have to figure out the 5.99% interest rate.

150 x 5.99 = 8.99

150 + 8.99 = $158.99

Now multiply that by 16

158.99 x 16 = $2,543.84 is your answer.

PLEASE, PLEASE, PLEASE HELP ME!!!! I NEED THE ANSWER IN ONE HOUR!!! Ben has 57 toys. 15 of them are new, 9 are his favorite ones

storchak [24]

So.... there are a total of 57 toys, which the new and favorites ones are not going to be sold.

The equation would ultimately go into 57 - (15+9+2), which would equal to 31. Ultimately, he sells 31 toys and have 26 left over.

in short, subtracting 57 with the sum of 15+9+2 would equal to 31 toys which means that he sells the 31 toys.

The manager of a restaurant found that the cost to produce 200 cups of coffee is $65.00 , while the cost to produce 250 cups i

PIT_PIT [208]

Answer:

a). y = 0.25x + 15

b). x = 480 cups

Step-by-step explanation:

(a). Let the equation of the linear function passing through a point (x', y') is,

y - y' = m(x - x')

'm' = slope of the line

b = y-intercept

Two points lying on the linear function will be (200, 65) and (250, 77.5).

Slope of the line 'm' = $\frac{y_2-y_1}{x_2-x_1}$

m = $\frac{77.5-65}{250-200}$

= $\frac{12.5}{50}$

= 0.25

Therefore, equation of the line passing through (200, 65) and slope 0.25 will be,

y - 65 = 0.25(x - 200)

y - 65 = 0.25x - 50

y = 0.25x + 15

(b). For y = $135 we have to calculate the number of cups of coffee produced.

135 = 0.25x + 15

0.25x = 135 - 15

0.25x = 120

x = 480 cups

Therefore, 480 cups of coffee will be produced.

Because the ratio of acceptance is 9:100, we simply multiply both by 2:

9:100 = 18:100
