Surface Area Formula:
A= 2 ( lw + lh + wh )

l = length
w = width
h = height

Step 1.) plug in what you know

A = 2 ( lw + l 22 + w 22 )

Step 2.) find the length & width

- look at the area.
- a rectangles area is made up of the length and width being multiplied together.
- by saying this, I’m going to estimate how much the length and width would be, and make sure they will add up to 22 when multiplied.
- so, I’m going to say that the length is 11, and the width is 2.

Step 3.) plug in everything and then solve

A= 2 (11•2) + (11•22) + (2•22)

To solve, you are going to first multiple everything in parentheses like so:

A= 2 (22) + (242) + (44)

And then you are going to multiply everything by the 2 like so:

A= (44) + (484) + (88)

And then you are going to combine them all together (by adding) and get:

A= 616

and that is your answer.

Answer:

40 inches

Step-by-step explanation:

16×20=320

320÷6=53.33

53.33×3=159.99

159.99÷4=39.9975

draw a rectangle give the length and the width to show that it has an area of 12cm make sure one side is longer than the other t

Elden [556K]

To find area, you multiply length * width. There are 4 sides on a number, so we need to have a equation like this. x * x * y * y = 12cm. If we do 4 * 4, we get 8. We could also use 2 * 2 = 4. 8 + 4 = 12. So, width = 8, and length = 4.

Hope this helps! ☺♥

Solve the system of linear equations using either substitution or the elimination method.

lara31 [8.8K]

Answer:

x = -1

y = 2

Step-by-step explanation:

x + y = 1

y = -x + 1

y = -x + 1 (Multiply this by -1)

y = 3x +5

-y = x - 1

y = 3x +5

0 = 4x + 4

4x = -4

x = -1

x + y = 1

-1 + y = 1

y = 2

The expected total amount of time the operator will spend on the calls each day is of 210 minutes.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

n-values of normal variable:

Suppose we have n values from a normally distributed variable. The mean of the sum of all the instances is $M = n\mu$ and the standard deviation is $s = \sigma\sqrt{n}$
