Answer:

The length of the rectangular playing field is 177 yards and the width is 46 yards

Step-by-step explanation:

Let

x -----> the length of the rectangular playing field

x -----> the width of the rectangular playing field

we know that

The perimeter of the  rectangular playing field is

P=2(x+y)

P=446 yd

so

446=2(x+y) ------> equation A

x=4y-7 -----> equation B

Solve the system by substitution

Substitute equation B in equation A and solve for y

446=2(4y-7+y)

223=5y-7

5y=223+7

5y=230

y=46

Find the value of x

x=4(46)-7

x=177

therefore

The length of the rectangular playing field is 177 yards and the width is 46 yards

Noah was assigned to make 64 cookies for the bake sale. He made 25% MORE than that. How many cookies did Noah make? Explain how
bazaltina [42]

Answer:

8 cookies were left after the bake sale. 72 were sold.

Step-by-step explanation:

64*1.25= 80

80*.9= 72

8

125% of 64 is equal to 80.

90% of 80 is equal to 72.

The number left was 10% of the number he made. The number he made was 125% of 64, so the number left was 8

 10% × 125% × 64 = 0.125 × 64 = 8

thats all i could really come up with at the top of my head

A skateboarding ramp is 13in. high and rises at an angle of 13°. How long is the base of the ramp? Round to the nearest inch.
charle [14.2K]
<h3>Answer:  Approximately 56 inches</h3>

===========================================================

Explanation:

The diagram is shown below. We know the vertical part of the triangle is 13 inches, which is the side opposite the reference angle 13 degrees. The adjacent side is unknown. We'll call it x. This is how long the base of the ramp is, which is the horizontal distance along the entire ramp. This distance is on the ground. The ramp itself is the hypotenuse but it seems like your teacher isn't wanting to know this value. So we'll ignore the hypotenuse.

We'll use the tangent rule to connect the opposite and adjacent sides.

tan(angle) = opposite/adjacent

tan(13) = 13/x

x*tan(13) = 13

x = 13/tan(13)

x = 56.309186365694

x = 56 inches is the approximate horizontal distance underneath the ramp
