The surface area of the given figure is 90 feet².
What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object.
The given figure is a rectangular prism.
A rectangular prism consists of 4 rectangular lateral faces and 2 rectangular bases.
Surface area of the rectangular prism is the area of each of the faces.
Combining all these area, area of a rectangular prism can be found by the formula,
Area = 2 (lw + wh + lh)
where l is the length, w is the width and h is the height.
Given, l = 3 feet, w = 3 feet and h = 6 feet
Area = 2 [ (3 × 3) + (3 × 6) + (3 × 6)]
= 2 (9 + 18 + 18)
= 90 feet²
Hence the surface area is 90 feet².

Ben and Carson went to the movies with friends. Ben purchased 3 popcorn and 2 boxes of candy for $41. Carson purchased 1 popcorn and 2 boxes of candy for $29. How much did the popcorn cost?
Answer:
$6
Step-by-step explanation:
B- 3P+2C=$41
C-1P+2C=$29
since they both bought at least 1 popcorn and 2 candy you can just subtract 29 from 41. you get 12 which equals the other 2 popcorns that ben bought
12/2=6
since you need to find the price of 1 popcorn you have to divide 12 by 2

Ray is x years old. His brother Ron is y years older than Ray.
What will the difference of their ages be in 5 years?
ray is x years old
Ron is x+y years old
in 5 years ron will be 5 years older than now, so x+y+5 years old
orAnswer:
x - x + y + 5 - 5 = y or x + y - x = y
Step-by-step explanation:
The difference now,
x + y - x = y
The difference in 5 years,
(x + y + 5) - (x + 5) = x - x + y + 5 - 5
x - x + y + 5 - 5 = y
The difference in their ages never changes

Write a polynomial function of least degree with integral coefficients that has the given zeros.
Answer:
Step-by-step explanation:
To get the equation, you must create the factors containing the roots.
So for example the first set of roots can be produced from
(x -2)(x^2 + 9)
which equals (when expanded) x^3 + 9x - 2x^2 - 18 which when put in the correct order gives
x^3 -2x^2 + 9x - 18

The total dimension of the aquarium that will be cleaned by Steve will be 94 meters.
How to illustrate the dimensions?Your information isn't given. Therefore, an overview will be given. In this case, let's assume that the aquarium is rectangular. Let's assume the dimensions are 20m by 27m.
In this case, since she needs to clean the four walls of the aquarium, the total distance that will be cleaned will be:
= 2(Length + Width)
= 2(27 + 20)
= 2 × 47
= 94m
In conclusion, 94m will be cleaned.

3/4 of ... is 12 I neeed your help please help me
Answer:
The number is 16.
Step-by-step explanation:
So we need to find 3/4 of a number to get 12.
We don't know what the number is, so we assign it a variable. We will assign the variable x and try to solve it.
We translate our problem into an equation. Since x is the variable and we multiply by 3/4, we get the value of 12, which is exactly what we are trying to do.
(3/4)(x) = 12
To solve, we multiply both sides by 4/3, because in order to solve for x (the variable), it needs to be separated and isolated from everything else.
(4/3) * (3/4)(x) = (4/3) * 12
4/3 * 3/4 = 1 and (4*12)/3 = 48/3 = 16
x = 16
The number is 16.
Find the area of a green shaded region in the figur
Answer:
The answer is 156cm^2
Step-by-step explanation:
Solution:
The shape given is a trapezium.
The area of the green region = Area of the outer trapezium - Area of the inner trapezium.
[tex]Area\: of\:a\:trapezium\:=\frac{1}{2}\:(a+b)h[/tex]
[tex]Where\: a,b\:are\:the\:bases,\:h=height[/tex]

[tex]a=10cm,\:b=14cm,h=16cm[/tex]
[tex]Area\:of\:the\:outer\:trapezium=\frac{1}{2}\:(10+14)16[/tex]

there are 36 pupils in a class.the number of boys is twice the number of girls.how many are girls?
Answer:
12 girls
Step-by-step explanation:
Boys to girls ratio= 1:2
Thats means there are (1+2) 3 total parts.
So [tex]\frac{36}{3}[/tex]=12
Each part is 12 so
boys is 12*2= 24 boys
Girls id 12*1= 12 girls
Answer:
12
Step-by-step explanation:
Total number of students in class ⇒ 36
Given that,
The number of boys is twice the number of girls.
First, let us make an expression to find the number of girls.
For that, let the number of girls be x.
Number of girls ⇒ x
Number of boys ⇒ 2x
Total number of pupils ⇒ x + 2x
So,
x + 2x = 36
3x = 36
Divide both sides by 3.
x = 12
Therefore, there are 12 girls and 24 boys in the class.
