Jason puts $30 worth of gas in his truck. The price per gallon was $2.50. Which equation can be solved to find the number of gal
tankabanditka [31]

So, this is a rate problem, so the forumla we would get is


2.5g=30

(Note this is not one of the choices), so if we look, there is an equivelent equation.

If we divide both sides by g we get

2.5=30/g

B is the correct answer

A water storage tank is in the shape of a cone with the pointed end down. If the radius is 21 feet and the depth of the tank is
andre [41]

The volume of the water storage tank is the amount of space in it

The volume of the water storage tank is 6468 cubic feet

<h3>How to determine the volume?</h3>

The given parameters are:

Radius (r) = 21 feet

Height (h) = 14 feet

The shape of the water storage tank is a cone.

And the volume of a cone is:

V = 1/3πr^2h

So, we have:

V = 1/3 * 22/7 * 21^2 * 14

This gives

V = 6468

Hence, the volume of the water storage tank is 6468 cubic feet

a line with the slope of -2 passes through the point (1,7) what is the closest point on the line above (1,7) which has a whole n
deff fn [24]
The closest point above on this line is (0,9)

You can find this by using the rise over run method. Since the slope is -2, we can move to the next whole number point by observing the fraction 2/-1.

Rise = 2
Run = -1

If you start on the point (1,7) and rise two, it will bring you to (1,9), then you have to move back one space (or run) to (0,9).

Need some help, kinda stuck
ElenaW [278]

Answer:

7/4

Step-by-step explanation:

\displaystyle\frac{2 +  \sqrt{ - 3} }{2} ( \frac{2 -  \sqrt{ - 3} }{2} )~~~~~~

Evaluate.

Solution:

Rewrite it as,

  • \displaystyle\frac{2 +    \sqrt{  - 1 }  \sqrt{  3} }{2} ( \frac{2 -  \sqrt{ - 1}  \sqrt{3} }{2} )
  • \displaystyle\frac{2 +  i\sqrt{  3} }{2} ( \frac{2 -  i\sqrt{ 3} }{2} )~~~~~~

Multiplying them,

  • \displaystyle\frac{(2 +  i\sqrt{  3})\times(2 - i \sqrt{3})   }{2 \times 2}

  • \displaystyle\frac{(2 +  i\sqrt{  3})\times(2 - i \sqrt{3})   }{4}

Applying Distributive property,

  • \displaystyle\frac{2(2 +  i\sqrt{  3}) +  \: i \sqrt{3} (2 - i \sqrt{3})   }{4}

  • \cfrac{2 \times 2 + 2( - i \sqrt{3} ) + i \sqrt{3}(2 - i \sqrt{3} ) }{4}

  • \cfrac{2 \times 2 + 2( - i \sqrt{3}) + i \sqrt{3}   \times 2 + i \sqrt{3} ( - i \sqrt{3}) }{4}

Combining each terms,

  • \cfrac{4 - 2i \sqrt{3} + 2i \sqrt{3}   + 3}{4}
  • \cfrac{ - 2i \sqrt{3}  + 2i \sqrt{3} + 7 }{4}
  • \boxed{\cfrac{ 7}{4} }

Last Choice is accurate.
