a rectangular prism measures 8 inches in width, 12 inches in length, and 4 inches in height. what is the surface area of the pri

laiz [17]

For this case we have that the surface area of the prism is given by:

$SA = A_ {l} + 2B$

Where:

$A_{l}$ : Is the lateral area

B: It is the area of the base

$A_ {l} = P.h$

Where:

Q: It is the perimeter of the base

h: It's the height

$A_ {l} = 40 * 4\\A_ {l} = 160 \ in ^ 2$

On the other hand:

$B = 12 * 8\\B = 96 \ in ^ 2$

So, we have:

$SA = A_ {l} + 2B\\SA = 160 \ in ^ 2 + 2 * 96 \ in ^ 2\\SA = 352 \ in ^ 2$

Answer:

$SA = 352 \ in ^ 2$

The equation P = 21 + 2w can be used to find the perimeter of a rectangle. A 1 point rectangular shaped playground is enclosed b

nalin [4]

Answer:

130 m

Step-by-step explanation:

Given:

P = 2l + 2w
P = 500 m

Length is:

l = 120 m

Substitute values and solve for w:

500 = 2*120 + 2w
2w = 500 - 240
2w = 260
w = 260/2
w = 130 m

What is 0.7, 0.755, 5/8 from least to greatest?

Margarita [4]

I like to start by turning all my numbers into the same form. You can go either way but I am going to turn the decimals into fractions. so 0.7 is the same as 7/10.

0.755 is like 755/1000 which can be reduced to 151/200 (if you don't understand the convertions let me know i will explaine more.)

Next give all the fractions a common denominator. both 8 and 10 go into 200 so we can use that. 151/200 already has a denominator of 200 so that one is set.
for 7/10 well, 10 time 20 is 200 so multiply both the numerator and the denominator by 20 so you get 140/200
the last one is 5/8 8 times 25 is 200 so multiply both numbers by 25 to get 125/200

the fractionos we have are 125/200 151/200 and 140/200. Now because they all have the same denominator the one with the lowest numerator is the least number and the one with the highest number is the greatest number.

125/200 140/200 151/200 now just replace the original number with the order they are placed in.
125/200 was 5/8
140/200 was 0.7
151/200 was 0.755
so the final answer is
5/8, 0.7, 0.755

The distribution of number of hours worked by volunteers last year at a large hospital is approximately normal with mean 80 and

wariber [46]

Answer:

E 0.923

Step-by-step explanation:

The Z score is a measurement used in statistics to determine the relationship between a value and a mean of a group of values measured as standard deviation from the mean. The z score (z) is given as:

$z=\frac{x-\mu}{\sigma}$ , Where μ is the mean, σ is the standard deviation and x is the value.

Given that:

σ = 7, μ = 80 and x = 90

$z=\frac{x-\mu}{\sigma}=\frac{90-80}{7} =1.43$

From the normal distribution table, P(X < 90) = P(z < 1.43) = 0.923
