The height and weight of adults can be related by the equation y=48.3x−127 where x is height in feet and y is weight in pounds.

suter [353]

we conclude that the correct option is A, the slope is:

<em>"the average number of pounds per foot tall"</em>

<h3>What does the slope of the line represent?</h3>

The linear equation:

y = 48.3*x - 127

Relates the height, x, and the weight, y of an adult.

Then the slope, which is 48.3, should have units of mass over height.

Now, if x is in feet and y is in pounds, then the slope has units of pounds/feet.

Then it represents the mean number of pounds per feet. So we conclude that the correct option is A:

"the average number of pounds per foot tall"

I need help, lmk if you can do them..

OLEGan [10]

Answer:

25) cos X = 12/37 cos X = 0.3243 X = 71.08 degrees

26) tan C = 32/24 tan C = 1.3333 C = 53.13 degrees

27) sin Z = 15/25 sin Z = 0.6 Z = 36.87 degrees

28) sin A = 32/40 sin A = 0.8 A = 53.13 degrees

29) sin Z = 40/50 sin Z = 0.8 Z = 53.13 degrees

Working alone and at a constant rate, Machine A takes 3 hours to create a widget. Machine B, working alone and at a constant rat

PilotLPTM [1.2K]

Answer:

Time required by Machine B to create a widget = 4 hours

Step-by-step explanation:

Time taken by Machine A ( $T_{A}$ ) = 3 hours

Time taken by Machine B ( $T_{B}$ )= x hours

Time taken by both machines by working together = 12 hours

The time required to both machines by working together to finish a task is given by the formula = $\frac{T_{A} {T_{B} } }{T_{A} + T_{B} }$

Put the values in above formula we get

⇒ T = $\frac{3 x}{3 + x}$

⇒ 12 = $\frac{3 x}{3 + x}$

⇒ 36 + 12 x = 3 x

⇒ x = - 4 hours

This is the time required by Machine B to create a widget.
