An arts academy requires there to be 3 teachers for every 63 students and 5 tutors for every 60 students . How many students does the academy have per teacher? Per tutor? How many tutors does the academy need if it has 120 students?
Answer:
6 teachers and 10 tutors.
Step-by-step explanation:
if there are 120 student and they need 3 teachers per 63 students then there would be 6 teachers because 63x2=126 subtract the six and you get the number of students. 120 so 6 teachers and if they need 5 tutors per 60 student then double the students to get 120 and double the tutors to get 10.

Ratio to 54 seconds to 2 minutes
Computation:
We know that,
1 minutes = 60 second
So,
2 minutes = 120 second
Ratio to 54 seconds to 2 minutes = 54 / 120
Ratio to 54 seconds to 2 minutes = 27 / 60
Ratio to 54 seconds to 2 minutes = 9 : 20

1. Employees of a landscaping company built a retaining wall with area 23(3/8) sq ft. They used brick to make the top portion of the wall, which is 8(1/2) feet. What is the total height of the wall? Write an equation to represent the situation. Then solve. Part 2: If the area of the brick portion of the wall is 15(7/12), what fraction of the wall is brick? Write an equation to show your work.
Answer:
a. h = A/w = 2 ³/₄ ft
b. A'/A = 2/3
Step-by-step explanation:
a. What is the total height of the wall? Write an equation to represent the situation. Then solve.
The wall is a rectangle and its area is A = wh where w = width and h = height of wall.
Making h subject of the formula,
h = A/w
Now, Since the area of the retaining wall, A is 23 ³/₈ ft² and its width is the length of the portion of the wall which is brick w is 8 ¹/₂ ft, then
h = A/w
= 23 ³/₈ ft² ÷ 8 ¹/₂ ft
= 187/8 ft² ÷ 17/2 ft
= 187/8 ft² × 2/17 ft
= 187/4 ft² × 1/17 ft
= 187/68 ft
= 2 ³/₄ ft
b. If the area of the brick portion of the wall is 15(7/12), what fraction of the wall is brick? Write an equation to show your work.
Since the area of the brick portion of the wall is A' = 15 ⁷/₁₂ ft² and the total are of the retaining wall is A = 23 ³/₈ ft²
The fraction of the wall that is brick = A'/A
= 15 ⁷/₁₂ ft² ÷ 23 ³/₈ ft²
= 187/12 ÷ 187/8
= 187/12 × 8/187
= 8/12
= 2/3
Answer with Step-by-step explanation:
a) 2 3/4 ÷ 3 = 11/12 feet
11/12 + 11/12 = 1 5/6
Or, you could write an algebraic equation:
2 3/4 ÷ 3 = x. (3x = 2 3/4)
x = 11/12
The height of the brick proportion of the wall is 1 5/6
b)
You know that 8 x 2 is 16. Well, you already know that the whole total of fractions, multiplied together, would probably be less that 1 and less than 1/2.
So, your rounded answer should be 16. Or 16 1/2
c)
Area = 8 1/2 x 2 3/4.
Use Distributive Property to solve the area.
(8 x 2) + (3/4 x 1/2) = x
8 x 2 = 16
3/4 x 1/2 = 3/8
16 + 3/8 = 16 3/8
x = 16 3/8
I think my answer is reasonable because I estimated 16, and 1/2. 3/8 is close to 1/2. That's why my answer is reasonable.

Gabrielle uses 7.6 pints of blue paint and white paint to paint her bedroom walls. 1 4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls
Answer:
1.9
Step-by-step explanation:
Gabrielle uses 7.6 pints of blue and white paint to paint her bedroom
1/4 of the paint is blue paint
Therefore the amount of white paint she used to paint her bedroom can he calculated as follows
= 1/4
= 0.25×100
= 25%
25/100×7.6
= 2.5 × 7.6
= 1.9
Hence 1.9 pints of white paint was used to paint the room

What is the solution for the following system of equations?
2x + y = 7
x - 2y = 6
I got you bro!
Answer:
{x,y} = {4-1}
You might be wondering how I got this, well here are the steps:
System of Linear Equations entered :
[1] 2x + y = 7
[2] x - 2y = 6
Graphic Representation of the Equations :
y + 2x = 7 -2y + x = 6
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = 2y + 6
// Plug this in for variable x in equation [1]
[1] 2•(2y+6) + y = 7
[1] 5y = -5
// Solve equation [1] for the variable y
[1] 5y = - 5
[1] y = - 1
// By now we know this much :
x = 2y+6
y = -1
// Use the y value to solve for x
x = 2(-1)+6 = 4
Solution :
{x,y} = {4,-1}
