The answer is 24. Because there are 6 number in the set (including x) the product of the avg. (22) and the amount of numbers (6) should equal what the total of the sum of number, so you should end up with an equation like this: x+20+17+18+24+29=132. If you combine the like terms you get: x+108=132. Subtract 132 from both sides to make the equation equal to x and you get x=24

Answer:

Therefore, x = 24 .

Step-by-step explanation:

Given : The average of six numbers is 22. The numbers are 20,17,18,24,29 and x

To find : Find x.

Solution : We have given The average of six numbers is 22.

mean = \frac{20+17+18+24+29+x}{6}.

Mean = 22

22 = \frac{108+x}{6}.

On multiplying both sides by 6

22 *6 = 108 + x .

132 = 108 + x

On subtracting both sides by 108.

132 -108 = x

24 = x .

Therefore, x = 24 .

A child's sandbox is 5 feet wide, 4 feet long, and 3 feet deep. Grace fills the sandbox so that the sand is 2 ½ feet deep. What
8_murik_8 [283]

Answer:

the volume of sand is 50 ft^{3}

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, rectangular prism.

Given data

Length  l= 4 ft Width w= 5ft\\Height h = 3ft

if the sandbox is filled with sand of 2\frac{1}{2 } ft deep the volume of the sand in the box will be calculated based on the the depth of the sand

converting the depth of sand from mixed fraction to proper fraction we have 2\frac{1}{2} = \frac{5}{2}

the expression for the volume of a rectangular prism is

volume of sand = length * width* height

substituting our data into the expression we have

volume of sand= 5*4 * \frac{5}{2} \\volume of sand = \frac{100}{2} \\volume of sand = 50 ft^{3}
