Answer:

  y = 21/x

Step-by-step explanation:

The inverse variation relation means ...

  y = k/x

For the given values, we can determine the constant k:

  3 = k/7

  3×7 = k = 21

Then the function is ...

  y = 21/x

What is the approximate area that is shaded red?
Mashcka [7]

To find the area that is shaded red, you find the area of the rectangle and subtract it by the area of the triangle.


Area of a rectangle:

A = l × w             [ l = 11 in ; w = 6in ]    Plug these numbers into the equation

A = 11 · 6

A = 66 in²


Area of a triangle:

A=\frac{1}{2}bh     [ b = 4 in ; h = 6 in ] Plug these #s into the equation

A = \frac{1}{2}(4)(6)

A=\frac{24}{2}

A = 12 in²


Area of rectangle - Area of triangle = Area of the shaded region

66 in² - 12 in ² = 54 in²


Your answer is B

If the measure of an angle is p is three times less than twice the measure of angle q and angle p and angle q are supplementary
Marizza181 [45]
60 * 3 = 180 and 90 * 2 = 180
if they are supplementary angles than they equal 180 together. 
angle p is three times less than twice the measure of angle q so that means 180/3 = angle p and 180/2 = angle q. 
Angle q is 90 and twice that is 180 and Angle p is 60 and three times that is 180
so 60 is three times less than twice the measure of 90.
60 three times is 180 and 90 twice is 180 which means 3p = 2q and you have 180 because they are supplementary angles so you have really 180/3 = p and 180/2 = q
The answer is p = 60 and q = 90

Convert 30 feet per second to miles per minute.
Amanda [17]

We know that:

1 mile = 5280 ft

1 minute = 60 sec

 

Therefore to convert this we simply use the conversion factors:

 

(30 ft / s) * (60 s / 1 min) * (1 mi / 5280 ft) = 0.34 mi / min

 

 

So we got 0.34 miles per minute.
