Juwan has a third quiz in math on Friday. His two previous quiz grades were 85 and 72. What must he make on the third quiz for h

VLD [36.1K]

Answer:

$x = 107$

Step-by-step explanation:

Given

$Scores = 85\ and\ 72$

$Average = 88$

Required

Determine the third score

Average is calculated using;

$Average = \frac{\sum x}{n}$

In this case:

$n = 3$

$Average = \frac{\sum x}{n}$

Let the third score be x; So:

$Average = \frac{85 + 72 + x}{3}$

Substitute 88 for Average

$88 = \frac{85 + 72 + x}{3}$

$88 = \frac{157 + x}{3}$

Multiply through by 3

$3 * 88 = \frac{157 + x}{3} * 3$

$264 = 157 + x$

$x = 264 - 157$

$x = 107$

A rectangular container that has a length of 30 cm, a width of 20 cm, and a height of 24 cm is filled with water to a depth of 1

BaLLatris [955]

Answer:

$5400cm^{3}$ more water could be added to the container before the container overflows

Step-by-step explanation:

The volume of the rectangular container is got by multiplying its given dimensions: Length X breadth X height

This will be 30 X 20 X 24 = $14400 cm^{3}$

To find the volume of water inside the rectangular container, we will use the new height for our computation of volumes, keeping the length and breadth of the cylinder the same.

This will be $30 \times 20 \times 15 =9000 cm^{3}$

The volume of water needed to be added until the container overflows will be got by subtracting the volume of water present in the container from the total volume of the container

$14400 - 9000 =5400cm^{3}$
