Help find the surface area

Answers

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

A zookeeper is 6 and 1/4 feet tall. A young giraffe in her care is 9 and 3/8 feet tall. What fraction of the giraffes height is the zookeepers?

Answers

Answer:

3 1/8

Step-by-step explanation:

Subtract and then simplify

Answer:

Step-by-step explanation:

1. You know that:

- The zookeeper is 6 1/4 feet tall.

- The young giraffe is 9 3/8 feet tall.

2. Then, to calculate how many times as tall as the zookeeper is the girraffe, you only need to divide the height of the giraffe by the height of the zookeeper:

- Let's rewrite each height as a decimal number: divide the numerator and the denominator of the fraction and add the result to the whole number:

- Divide 9.375 feet by 6.25 feet, then you obtain the following result:

Describe the probability of rolling a die and landing an even number while tossing a coin and landing on heads.

A. as likely to happen as not to happen

B. impossible

C. likely

D. unlikely

Answers

Answer:

d

Step-by-step explanation:

The first step is to find the possibility of the die landing on an even number which is 3/6 as there are 6 possible turn outs and 3 of them are even. Which means the probability is 3/6 or in its simplified version 1/2. The second step is to find the probability of landing on heads which is 1/2 as there are 2 possible turn outs and 1 of them is heads. Which means the probability is 1/2 (it cannot be simplified) . To find the probability of both we need to times them together so 1/2×1/2= 1/4. So the probability of getting both is 1/4 which is unlikely probability so the answer is D .

Water starts out at a temperature of 62 F . It is heated such that its temperature increases at a rate of 8 F per minute. It takes m minutes to reach a boil at 212 . Set up and solve an equation to find out the value of m. (Warning, decimal answer!) I will give brainliest,putting in 12 points!

Answers

Answer:

Step-by-step explanation:

since it starts at 62 and finishes at 150 u can find out that the increase in temp is 150F and since it increases by 8 every minute u can come to find that the increase in temp (150) divided by the amount it increases 8 is 18.75 which is the amount of minutes it took

62 + 8m = 212
8m = 150
m = 18.75

HELPPP I NEED THE ANSWER FAST PLEASEEE Shirley is buying a $27 scarf. If the sales tax is 7.25% and she hands the cashier $30, how much change will she get back? YOU GET 86 POINTS FOR ANSWERING THIS BECAUSE I HAVE A C- IN MATH

Answers

Hi, I think the answer should be $4.26

7.25% × $24 = $1.74

$24 +1.74 = $25.74

Change is the difference between the amount tendered and this total amount:

$30.00 -25.74 = $4.26

Answer: $1.04

Step-by-step explanation:

Cost of scarf = $27

sales tax = 7.25% of 27 = $1.9575 (round to $1.96)

Total cost = 27 + 1.96 = $28.96

$30.00 - $28.96 = $1.04 change
