Step-by-step explanation:

Area = 8 × 5

Area = 40^2

Perimeter is the length around the edges

Therefore it is 8+8+5×5 (since there are 4 edges)

Perimeter = 2×8 + 2×5

= 40 + 10

= 50cm

If the mean of 5 positive integers is 15, what is the maximum possible difference between the largest and the smallest of these

Vikki [24]

Answer:

if the 5 numbers are different, the maximum difference is 64

Step-by-step explanation:

We have 5 positive (different) integers, a, b, c, d and e (suppose that are ordered from least to largest, so a is the smallest and b is the largest.

The mean will be:

M = (a + b + c + d + e)/5 = 15.

Now, if we want to find the largest difference between a and e, then we must first select the first 4 numbers as the smallest numbers possible, this is:

a = 1, b = 2, c = 3 and d = 4

M = (1 + 2 + 3 + 4 + d)/5 = 15

M = (10 + d)/5 = 15

10 + d = 15*5 = 75

d = 75 - 10 = 65

then the difference between a and d is = 65 - 1 = 64.

Now, if we take any of the first 4 numbers a little bit bigger, then we will see that the value of d must be smaller, and the difference between d and a will be smaller.

Answer:

97 cm

Step-by-step explanation:

The perimeter is the sum of the side lengths. Starting from the upper left corner and working clockwise, the side lengths are ...

10 +3 +33 +15 +33 +3 = 25+2(36) = 97 . . . cm

The perimeter of the figure is 97 cm.

Rewrite the expression with rational exponents as a radical expression

Ann [662]

Answer:

$5\sqrt[4]{x}$ or the fourth answer

Step-by-step explanation:

Apply the rule $x^{\frac{m}{n}}=\sqrt[n]{x^m}$ to rewrite the exponentiation as a radical.

$5\sqrt[4]{x^1}$

Anything raised to 1 is the base itself.

Answer = $5\sqrt[4]{x}$

Need help quick simplify the expression (-4) power of 3

dezoksy [38]

Answer:

-64

Step-by-step explanation:

The question is asking to solve $(-4)^3$

Notice how the -4 is in parenthesis. This means that along with the 4 being multiplied, the negative is too.

$(-4)^3$ is the same as -4 · -4 · -4

First let's figure out if this will be negative or positive

Whenever the exponent is odd and there is a negative in the parenthesis the answer will be negative and if its even it will be positive

Now find out what 4 x 4 x 4 equals (64)

In conclusion the answer is -64
