Answers

Answer:

$45

Step-by-step explanation:

THIS IS THE COMPLETE QUESTION BELOW;

For a walk-a-thon a sponsor committed to give you a flat fee of $5 plus $2 for every mile you walk. If you walk for 20 miles, what is the total amount you will collect from your sponsor at the end of the walk-a-thon?

$5 was given for participants of the walk-a-thon.

$2 was given for every miles won

Then, for "y" number of miles, the the amount that can be won is ( 2×y)= 2y

The Total amount that can be given

= (5 + 2y)

Where "y" is the miles value

Then, if you walk for 20 miles, The Total amount that can be given

= 5 + 2(20)

= 5+ 40

= $45

the perimeter of the floor of a room is 18 metre and its height is 3 cm what is the area of 4 walls of the room

Answers

Note: The height of the room must be 3 m instead of 3 cm because 3 cm is too small and it cannot be the height of a room.

Given:

Perimeter of the floor of a room = 18 metre

Height of the room = 3 metre

To find:

The area of 4 walls of the room.

Solution:

We know that, the area of 4 walls of the room is the curved surface area of the cuboid room.

The curved surface area of the cuboid is

[tex]C.S.A.=2h(l+b)[/tex]

Where, h is height, l is length and b is breadth.

Perimeter of the rectangular base is 2(l+b). So,

[tex]C.S.A.=\text{Perimeter of the base} \times h[/tex]

Putting the given values, we get

[tex]C.S.A.=18\times 3[/tex]

[tex]C.S.A.=54[/tex]

Therefore, the area of 4 walls of the room is 54 sq. metres.

x= 33.9

Step-by-step explanation:

use cosine because x is the adjacent and 40 is the hypotenuse

set up your equation:

cos(32)= (x/40)

multiply both sides by 40:

40(cos(32))= (x/40)40

40(cos(32))= x

multiply 40 by the cos(32):
