a roller skating rink offers a special rate for birthday parties. On the samr day, a party for 10 skaters cost $107 and a party

olga nikolaevna [1]

Answer:

$119

Step-by-step explanation:

Let

x -----> the number of skaters

y -----> the cost for birthday parties

we have the points

(10,107) and (15,137)

step 1

Find the slope of the linear equation

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{137-107}{15-10}$

$m=\frac{30}{5}=6\ \frac{\$}{skater}$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=6\\point\ (10,107)$

substitute

$y-107=6(x-10)$

step 3

Convert to slope intercept form

$y-107=6x-60$

$y=6x-60+107$

$y=6x+47$

step 4

How much would a party for 12 skaters cost?

For x=12 skaters

substitute the value of x in the equation and solve for y

$y=6(12)+47$

$y=\$119$

How do you divide 9/4 divided by 10/3

NeTakaya

Answer:

You do (Keep, Change, Flip)

so you keep 9/4

Then change the division sign to multiplication sign

Finally flip the next fraction (10/3) becomes 3/10

9/4 * 3/10 = (9*3)/(4*10) = 27/40

Find the area of the triangle with A =42 degrees, b = 8 feet, and c = 5 feet. Round to the nearest tenth.

emmasim [6.3K]

We will use the formula:
Area = 1/2*a*c*sinB

where a and c are the length of the sides and B is the angle between those 2 sides

Area = 1/2*5*8*sin42
Area = 20*sin42
sin 42 = <span>0.669130606359
Area = </span>13.38261212718

Rounded to the nearest tenth Area is equal to 13.4
