A student has earned scores of 87, 81, and 88 on the first 3 of 4 tests. If the student wants an average (arithmetic mean) of ex

Juli2301 [7.4K]

To find an average you take the numbers to be averaged and add them together then You take the number and divide it by the number of numbers, in this case 4, and that gives you the average.
on this problem you want to do the opposite. you know the average she wants, an 87, so you multiply it by 4. 87*4=348. then you add the three numbers you have (88,81 and 87) and you get 256.
then you subtract 256 from 348 and you get 92. 92 is your answer to check just add 87+81+88+92=348
348/4=87
87 was the average she wanted.
Hope this helped! good luck :)

For every 4 gallons of green paint he uses 3 gallons of blue paint. Drag the correct number of each type of paint into the box t

Inga [223]

Answer:

Amount of green color used =

$\dfrac{64}{7}\text{ gallons}$

Step-by-step explanation:

We are given the following in the question:

Every 4 gallons of green paint is mixed with 3 gallons of blue paint. to make a particular shade.

Ratio of green color to blue paint can be calculated as:

$=\dfrac{\text{Amount of green color}}{\text{Amount of blue color}}\\\\=\dfrac{4}{3}$

Amount of shade = 16

Amount of green paint = $4x$

Amount of blue paint = $3x$

Thus, we can write:

$4x + 3x = 16\\7x = 16\\\\x = \dfrac{16}{7}$

Amount of green color used =

$4x = 4\times \dfrac{16}{7} = \dfrac{64}{7}\text{ gallons}$

Amount of blue paint used =

$3x = 3\times \dfrac{16}{7} = \dfrac{48}{7}\text{ gallons}$
