What is the total surface area?? PLEASE HELP THIS IS A QUIZ IM SO CONFUSED

Mathematics
1 answer:
Elina [12.6K]2 years ago
7 0

Answer:

246 cm

Step-by-step explanation:

So I solved for the two triangles, 6x8=48/2=24, since there are 2, I multiplied by 2 to get 48 (Could've kept it just as 48 but it's good to keep the habit of dividing by 2 to get area of a triangle).  Then I did 6x9 for the front rectangle to get 54, and then solved for the right and back rectangle by doing 9x8 to get 72, 72x2=144

144+48+54= 246

dangina [55]

Ishaan to have a score of 97 on the next exam have an overall average of 85

What is the mean of exam scores?

The mean of exam scores is the sum of the scores divided by the number of exams taken, more like an average of all scores

Initially, average score on 4 exams is 82

average=total score/number of exams

average score on 4 exams=82

total score =unknown=assume it is

number of exams=4

82=x/4

x=4*82

x=328

In order to have an overall average score of 85, we would sum the total score of 4 exams and the fifth exam and divide by 5 exams

85=(328+y)/5

85*5=328+y

425=328+y

y=425-328

y=97

What is the quotient
mario62 [17]

Answer:

The quotient is 3x - 11 + 60/(x + 5) ⇒ 2nd answer

Step-by-step explanation:

* We will use the long division to solve the problem

- The dividend is 3x² + 4x + 5

- The divisor is x + 5

- The quotient is the answer of the division

- If the divisor not a factor of a dividend, the quotient has

  a remainder

* Lets solve the problem

- At first divide the first term in the dividend by the first term in

 the divisor

∵ 3x² ÷ x = 3x

- Multiply the divisor by 3x

∴ 3x (x + 5) = 3x² + 15x

-Subtract this expression from the dividend

∴ 3x² + 4x + 5 - (3x² + 15x) = 3x² + 4x + 5 - 3x² - 15x = -11x + 5

- Divide the first term -11x in the new dividend by the first

 term x in the divisor

∴ -11x ÷ x = -11

- Multiply the divisor by -11

∴ -11(x + 5) = -11x - 55

-Subtract this expression from the new dividend

∴ -11x + 5 - (-11x - 55) = -11x + 5 + 11x + 55 = 60

∴ The quotient is 3x - 11 with remainder = 60

* The quotient is 3x - 11 + 60/(x + 5)
