Answer:

<em>The width of the lid is 15 cm</em>

Step-by-step explanation:

<u>The Perimeter of a Rectangle</u>

Given a rectangle of width W and height H, the perimeter is calculated as:

P = 2(W + L)

Jon used 56 cm of ribbon to go around the edge of a rectangular lid. This means the perimeter is:

2(W + L) = 56

Dividing by 2:

W + L = 28

Since the lid was L=13 cm long, the width is:

W = 28 - 13 = 15

The width of the lid is 15 cm

A cliff diver jumps from a cliff that is 96 feet above the water. His jump can be modeled by a quadratic equation, h= -16t(expon

ladessa [460]

Answer:

The diver will take 2.449 seconds to enter the water.

Step-by-step explanation:

We have been given that quadratic equation for the diver jumps is

$h=-16t^2+96$

We have to find the time taken for the diver to enter the water. When the diver enters the water, the height becomes zero.

$0=-16t^2+96\\\\16t^2=96\\\\t^2=6\\\\t=\sqrt6\\\\t=2.449\text{ seconds}$

Therefore, the diver will take 2.449 seconds to enter the water.

In ΔQRS, the measure of ∠S=90°, QS = 12, RQ = 13, and SR = 5. What is the value of the tangent of ∠R to the nearest hundredth?

oee [108]

Answer:

2.40

Step-by-step explanation:

From the triangle QRS

RQ is the hypotenuse 13

QS is the opposite = 12

SR is the adjacent = 5

According to SOH CAH TOA

tan <R = opp/adj

Tan <R = qs/sr

Tan <R = 12/5

Tan <R = 2.40
