Find the Surface Area of the prism please

Answers

Answer:

1544 m³

Step-by-step explanation:

surface area = 2 × base + lateral area

 base = (10×20)÷2 = 100

 Lateral area = perimeter × height

                      = (20+14+14)×28

                      =1 344

Final answer :

surface area = 2 × base + lateral area

                     =  2 × 100 + 1344

                     =  200 + 1344

                     =  1544

Answers

Answer:

Mean: 13.5°

Median: 13.5°

Mode: 21°

Midrange: 13°

Step-by-step explanation:

Mean: Add all of the values together and divide by 8 (the number of values). This is also called average.

Median: The middle value when ranked lowest to highest. In this case there are an even number of values (8), so you have to use the average of the middle two, which are 12 and 15.

Mode: This is the most commonly appearing value, and in this case 21 is the only value that appears twice.

Midrange: To find this you add the highest and lowest values together and divide by two. In this case, those values are 5 and 21.

how to solve and answer for 4 1/3 - 2 1/5 ?

Answers

Answer : 2 2/15


To begin you need to convert the fractions into something they both can go into. Sometimes it is easier to multiple the two denominator of the fractions, which in this case it is.
So, 3 times 5 is 15
This means your going to convert your fraction into 15th

1/3 is 5/15
This is because you need to times the bottom by 5 in order to get 15, so you need to do the same with the top.

1/5 is 3/15
This is because you need to times the bottom by 3 to get 15 so you do the same with the top

Next you just subtract the amounts separately
4-2 = 2
5/15 - 3/15 = 2/15

This means your answer is 2 2/15

Answer:

2 2/15 or if you want it in decimal form it's 2.133

what is the value of y when: -5=y-7over 9

Answers

Answer:

y=-38

Step-by-step explanation:

Undo the things that are being done to the variable.

1: Multiply both sides by nine to undo division.

-45=y-7

2: Add 7 to both side to undo the subtraction.

-38=y

Thats your answer!

Answer:

the answer should be -38 which is option c.

Step-by-step explanation: To get the answer first of all try a number that could be -7 -7 which would be -14 dividing by 9 making the results to be  -1.55 or -1.56. So using the same steps trying to find the other answers what is the value of y and if you want use the process of elimination choosing an answer to eliminate and a reason why to eliminate it making it to option c which is the correct answer so sorry if i answer late and please give brainliest to the other people that answer first.
