Answer:
4
Step-by-step explanation:
The computation is shown below:
Given that
There are total number of students i.e. 48
The ratio at present is 4:1
Now the computer needed to make the ratio be 3:1
So let us assume the number of students be 4x
And, the number of computers be x
So the 4x = 48
x = 12
So the computer be 12
Now the new ratio is 3:1
Students be 3x
And, computers be x
So
3x = 48
x = 16
Now the more computer needed is
= 16 - 12
= 4
hence, this is the answer but the same is not provided in the given options
Mrs. Mitra needs to buy 4 more computers to make the ratio 3: 1
The present total number of students = 48
Ratio of the number of students to the number of computers = 4: 1
(Number of students) / (Number of computers) = 4/1
48 / (Number of computers) = 4/1
Number of computers = 48/4
Number of computers = 12
If the ratio of the number of students to the number of computers = 3:1
48 / (Number of computers) = 3/1
3(Number of computers) = 48
Number of computers = 48/3
Number of computers = 16
Additional number of computers = 16 - 12
Additional number of computers = 4
Mrs. Mitra needs to buy 4 more computers to make the ratio 3: 1

If x varies directly with y and x = -3 when y = 12, what is the constant of variation?
Answer:
k = - [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given that x varies directly with y then the equation relating them is
x = ky ← k is the constant of variation
To find k use the condition x = - 3 when y = 12
- 3 = 12k ( divide both sides by 12 )
[tex]\frac{-3}{12}[/tex] = k , that is
k = - [tex]\frac{1}{4}[/tex]

At a local fair, Molly sells bracelets. It costs her
$10 per bracelet for supplies and the local marke
charges her a one-time booth fee of $60. She
charges $20 for each bracelet.
a) Write a system of equations to represent this
situation (one equation for expenses and one
equation for income):
Answer:
10x + 60 ; 20x
Step-by-step explanation:
Given that:
Purchase price per bracelet = $10
Cost of booth = $60
Selling price per bracelet = $20
Hence,
Let number of bracelets = x
Expense equation :
(Price per bracelet * number of bracelet) + booth fee
(10 * x) + 60
10x + 60
Income equation :
Selling price * number of bracelets
20x

Three friends all live on the same street that runs west to east. Ben lives 8 blocks from ann. Carol lives 2 blocks from ben. If the street is represented by a number line and ann's house is located at 0, what are the possible locations for carol's house?
Answer:
i. 10 units (Carol's house is 10 units on the right from Ann's house)
ii. -10 units (Carol's house is 10 units on the left to Ann's house)
Step-by-step explanation:
A number line is a system that can be used to express the location of directed number on a straight line. It has an origin which is taken to be zero (0).
In the given question, Ann's house is located at 0 of the number line. Let 1 block be represented by 1 unit on the number line.
Thus, Ben lives 8 blocks from Ann implies that Ben's house is at 8 units from Ann's house.
Given that Carol's house is 2 blocks from Ben implies that Carol's house is 2 units from Ben.
So that,
The possible locations of Carol's house depends on its position with respect to Ann's house.
i. Carol's house = 8 + 2
= 10 units
This implies that Carol's house is 10 units on the right from Ann's house.
ii. Carol's house = - 8 - 2
= -10 units
This implies that Carol's house is 10 units on the left to Ann's house.

Mr. Allen needs to store his boat for winter. He needs to fill the gas tank and put fuel preserver in the tank. The fuel tank holds 70 gallons and fuel preserver mixes at a ratio of 1 oz. preserver to 2.5 gallons of gas. How much preserver will Mr. Allen need to use?
28 oz.
32 oz.
24 oz.
36 oz.
Answer:
Mr. Allen will need 28 oz. of preserver
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if p and g are proportional, then:
p = kg
Where k is the constant of proportionality.
Where p is the quantity of preserver Mr. Allen needs to store his boat for winter, and g is the gallons of gas of the tank.
We are already given the ratio of fuel preserver and gallons of gas as 1 oz:2.5 gallons.
The value of k is, then k=1/2.5. The proportion is written as:
p = g/2.5
Since the boat holds g=70 gallons of gas:
p = 70/2.5 = 28
Mr. Allen will need 28 oz. of preserver
