Answer:

QR ≈ 16.2 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle.

tan62° = $\frac{opposite}{adjacent}$ = $\frac{QR}{RP}$ = $\frac{QR}{8.6}$ ( multiply both sides by 8.6 )

8.6 × tan62° = QR , then

QR ≈ 16.2 ft ( to the nearest tenth )

To the nearest tenth, which is the BEST estimate for the volume of the given pyramid?

mixer [17]

Answer:

4.2 cubic inches

Step-by-step explanation:

Find the diagram attached

Volume of the rectangular pyramid = BH/3

B is the base area

H is the height of the pyramid

Given

Base area = 3.2in * 1.4in

Base area = 4.48sq. in

Height = 2.8in

Volume of the rectangular pyramid = 4.48*2.8/3

Volume of the rectangular pyramid = 12.544/3

Volume of the rectangular pyramid = 4.2 cubic inches

Craig’s Kimbrell of the Atlanta braves, can throw his fast ball at 102 miles per hour. Convert this rate to feet per second

omeli [17]

Firstly, you change it to miles per second and then to feet
102miles per hour(60×60s)
102 per 120s
Divide
102÷120
=0.85miles per second
Convert to feet
=4488 feet per second

Is y=10.2x a proportional relationship?

BabaBlast [244]

Answer:

Step-by-step explanation:

Yes!

The condition needed to get a proportional answer is the y intercept must be 0. No other value can be added on. It doesn't matter that the constant of proportionality is not an integer. x and y will always differ by 10.2 as a multiplied value

Put another way, the fraction y/x will always give 10.2

A line has the equation 3x–4y–12=0. Write the equation in slope-intercept form.

rjkz [21]

The slope-intercept form: y = mx + b

$3x-4y-12=0\ \ \ |+4y\\\\3x-12=4y\\\\4y=3x-12\ \ \ |:4\\\\y=\dfrac{3}{4}x-3$
