X is equal to 30 (vertically opposite angles)

y=180-50
=130 degrees (angles in a straight line equal to 180)

z=180-130-30 (angle sum of a triangle equal to 180)
z=20 degrees

music magic offers live streaming for $9.99 a month with downloads at $0.50 a song. You have $30 a month budgeted for this servi

marin [14]

Step-by-step explanation:

The equation 0.5s+ 9.99=30 describes the situation.

9.99 is the fixed amount

0.5 is the cost for each song download

30 is the maximum amount spend for a month

Here 's' represents the number of songs download

0.5s+ 9.99=30 means

0.5 times the number of songs plus the fixed cost 9.99 should be equal to 30 dollars.

The solution to this equation is s=40.02.

s= 40.02 means 40 songs can be downloaded as per the budget

The principal of East High School wants to buy a new cover for the sand pit used in the long-jump competition. He measured the s

Ganezh [65]

Answer: area is 286.16 ft²

Step-by-step explanation:

Length of the sand pit is 29.2 feet and the width is 9.8 feet.

L= 29.2 ft

W = 9.8 ft

To find out the area, all we have to do is multiply the lenght by the width:

And do not forget that to calculate the area, all units must be the same and for the area, it is always the unit squared, in this case, feet square or simply (ft²).

A = l*w

A = 29.2 * 9.8 = 286.16 ft²

The equation c = 35h + 60 describes a plumber's charges, c, for a job that takes h hours. Which statement is correct?

VikaD [51]

The complete question is

"The equation c = 35h + 60 describes a plumber's charges, c, for a job that takes h hours. Which statement is correct?

a. The domain of this function represents the total cost for a job

b. H is a function of C

c. The painter charges a $35 service fee in addition to an hourly rate

d. The painters hourly rate is $35.00"

The equation c = 35h + 60 describes a plumber's charges, c, for a job that takes h hours. So, the correct option is D. The painters hourly rate is $35.00

<h3>What is a function?</h3>

Function is a type of relation, or rule, that maps one input to specific single output.

The equation c = 35h + 60 describes a plumber's charges, c, for a job that takes h hours.

The fixed fee, or service fee, is $60.

$35 is the hourly fee since in the function, it is 35 that is multiplied by the number of hours.

So, the correct option is D. The painters hourly rate is $35.00

Two joggers run 8 miles north and then 5 miles west. What is the shortest

Verdich [7]

The shortest distance they have to travel to return to their starting point is 9.4 miles.

Explanation

The joggers run 8 mile north and then runs 5 miles west. we have to calculate the shortest distance they have to travel to return to their starting point.

The distance traveled north and west respectively makes the height and base of a right angled triangle.

to find the shortest distance to the starting point, the hypotenuse has to be determined.

height h=8 miles

base b=5 miles

using pythagoras theorem

$b^2+h^2=H^2\\5^2+8^2=H^2\\25+64=H^2\\89=H^2\\\\H=\sqrt{89} =9.433=9.4 miles$

The shortest distance to the starting point is 9.4 miles
