Answer: $1\dfrac{61}{64}\text{ cubic feet}$

Step-by-step explanation:

Given : The side length of cube = $1\dfrac{1}{4}\text{ feet}$

We know that the volume of a cube is given by :-

$\text{Volume}=(\text{side})^3$

Thus, the volume of the given cube is given by :-

$\text{Volume}=(1\dfrac{1}{4})^3\\\\\Rightarrow\ \text{Volume}=(\dfrac{5}{4})^3\\\\\Rightarrow\ \text{Volume}=\dfrac{5^3}{4^3}\\\\\Rightarrow\ \text{Volume}=\dfrac{125}{64}=1\dfrac{61}{64}\text{ cubic feet}$

Hence, the volume of the cube is $1\dfrac{61}{64}\text{ cubic feet}$

Answer:

1.95 cubic feet

Step-by-step explanation:

We are given that Emily stores her jewelry in a cube and the cube has a side length of $1\frac{1}{4}$ feet.

$1\frac{1}{4}$ feet in an decimal form is 1.25 feet.

We know that,

volume of a cube = s $^{3}$

where s is the side length of the cube.

So substituting this value of side length of cube in the formula to get:

Volume of cube = $(1.25)^3$ = 1.95 feet

Answer:

m = 44

Step-by-step explanation:

USe the pythagoream thyroem a^2 + b^2 = m^2. so 10^2 + m = 12^2

or 100 + m = 144. subtract 100 from both sides, you get m = 44

In a different plan for area codes, the first digit could be any number from 4 through 8, the second digit was either 3, 4, 5,

Snezhnost [94]

For the first digit, we have 5 options that are 4,5,6,7,8 . For the second digit, we have 4 options which are 3,4,5 or 6 and for the third digit, we have the options of all numbers except 2 or 5 that is 1,3,4,6,7,8,9,0 . SO we have 8 options for third digit . So to find the total number of options, we need to multiply all the possible options for each digit that is 5 times 4 times 8 = 160 . So the number of possible options are 160 .

The weight of football players is normally distributed with a mean of 200 pounds and a standard deviation of 25 pounds.Refer to

Dafna11 [192]

Given that

the weight of football players is distributed with a mean of 200 pounds and a standard deviation of 25 pounds.

And we need to find What is the minimum weight of the middle 95% of the players?

Explanation -

Using the Empirical Rule, 95% of the distribution will fall within 2 times of the standard deviation from the mean.

Two standard deviations = 2 x 25 pounds = 50 pounds

So the minimum weight = 200 pounds - 50 pounds = 150 pounds

Hence the final answer is 150 pounds.
