Rowan found that 4 out of 28 students in her class bike to school. What is the ratio of students that bike to school to the number of students that do not bike to school?
Answer:
4:24
Step-by-step explanation:
The ratio of the number of students who bike to school to the number of students that do not bike to school is 1:6.
What are the ratio and proportion?
The ratio is the division of the two numbers.
For example, 20/5 is the ratio while x ∝ 10 is the proportion.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given,
Total number of students = 28
Number of students that bike to school = 4
So,
A number of students that do not bike to school = Total number of students - Number of students that bike to school.
Number of students that not bike to school = 28 - 4 = 24
So, the ratio of the number of students that bike to school to the number of students that do not bike to school = 4/24 = 1/6.
Hence, The ratio of the number of students that bike to school to the number of students that do not bike to school is 1: 6.

James has a jar full of just pennies and nickels. The ratio of pennies to nickels is 8 to 3. Which of the following is the ratio of nickels to the number of all the coins?
(1) 3 to 11 (3) 3 to 8
(2) 5 to 8 (4) 8 to 11
Answer:
(1) 3 to 11
Step-by-step explanation:
Ratio of pennies to nickels is 8 to 3.
Pennies : nickels = 8 : 3
Pennies = 8
Nickels = 3
Total coins = pennies + nickels
= 8 + 3
= 11
Which of the following is the ratio of nickels to the number of all the coins?
Nickels : Total coins = 3 : 11
Or
= 3 / 11
Or
3 to 11
The correct answer is (1) 3 to 11
Luis purchased a laptop computer that was marked down by
[tex] \frac{2}{5} [/tex]
of the original price. What fractional part of the original price did Luis pay?
Answer:
Luis paid 3/5 of the original price
Step-by-step explanation:
Luis purchased a laptop with a fractional discount of 2/5 of the original price.
When dealing with fractional parts of a whole, the sum of all parts must equal 1. With this in mind, we can say:
Paid price + Discount price = Original price
Or, equivalently:
paid fraction + discount fraction = 1
From the above relation, it follows that:
paid fraction = 1 - discount fraction
[tex]\displaystyle \text{paid fraction }=1-\frac{2}{5}[/tex]
[tex]\displaystyle \text{paid fraction }=\frac{5-2}{5}[/tex]
[tex]\displaystyle \text{paid fraction }=\frac{3}{5}[/tex]
Luis paid 3/5 of the original price

12 1/3 square feet in 1/5 of an hour. How many square feet can she paint in one hour
Answer:
30 5/6 square feet
Step-by-step explanation:
Answer:
30 5/6 square feet
Step-by-step explanation:
First you need to know how much she can paint in 1/5 hour. So you're going to be dividing mixed numbers. To do that you need to make 12 1/3 a fraction:
12*3=36
36+1=37
12 1/3= 37/3
Divide by 2. With fractions you flip the second and multiply
37/3 ÷ 2/1 = 37/3 *1/2
Multiply top by top bottom by bottom
37*1=37
3*2=6
37/6 is what she can paint in 1/5 hour
Now you need to multiply that by 5 (5/5= 1 which means a full hour)
So we use 5/1 to multiply by 5 in fraction form.
37/6 * 5/1
37*5=185
6*1=6
Now simplify (turn it back into a mixed number)
185/6= 185÷6
30 with a remainder of 5

Write an inequality to show the range of possible lengths for the third side of a triangle with sides 12 and 8
Answer:
4 < s < 20
Step-by-step explanation:
The triangle inequality requires that any side of a triangle must have a length that is between the difference and the sum of the lengths of the other two sides.
For unknown side s, the length must be ...
(12 -8) < s < (12 +8)
4 < x < 20
__
Additional comment
The triangle inequality is usually written ...
a + b > c . . . . . for any assignment a, b, c to side lengths
If s is not the longest side, then we require ...
s +8 > 12 ⇒ s > 4
If s is the longest side, then we require ...
8 +12 > s ⇒ s < 20
__
Some authors write the inequality as ...
a +b ≥ c
This allows a "triangle" that looks like a line segment. It will have an area of 0. If your curriculum uses this version of the triangle inequality, then the answer to this question will be 4 ≤ s ≤ 20.

question: Zayn has 5 more than three times the number of stickers that cleo has. Cleo has 25 fewer stickers than zayn. WRITE THE SYSTEMS OF EQUATION TO REPRESENT THIS SITUATION. explain what the solution means
Answer:
Solutions:
Z = 35
C = 10
Systems of Equations:
Z = 3C + 5
C = Z - 25
Step-by-step explanation:
Z will be for Zayn and C will be for Cleo.
Z = 3C + 5
C = Z - 25
These are the systems of equations. To solve, plug one of the equations into their respected variable.
Z = 3(Z - 25) + 5
Z = 3Z - 20
20 = 2Z
Z = 10
C = 3C + 5 - 25
-2C = -20
C = 10
This proves that these equations are correct. To find the final solution, plug 10 into Z to find Zayn's amount , then plug the amount that was for Zayn into C to find Cleo's amount.
Z = 3(10) + 5
Z = 35
C = 35 - 25
C = 10
local income tax defention
Answer:
Local governments in several states impose a local income tax. Local taxes are in addition to federal and state income taxes. Local income taxes generally apply to people who live or work in the locality. As an employer, you need to pay attention to local taxes where your employees work.
If the local income tax is a withholding tax, then you are required to withhold it from employee wages. Or if the local income tax is an employer tax, you must pay it.
Local income taxes are typically used to fund local programs, such as education, parks, and community improvement.

One factory needs 6 buttons to make 1 witch costume. Fill in the rate table to determine how many witch costumes the factory can make with 18, 42, 66, or 84 buttons
Answer:
The factory can make 3 witch costume from 18 buttons
The factory can make 7 witch costume from 42 buttons
The factory can make 11 witch costume from 66 buttons
The factory can make 14 witch costume from 84 buttons
Step-by-step explanation:
Let us use the ratio method to complete the table
∵ A factory needs 6 buttons to make 1 witch costume
∵ There are 18 buttons
→ Find how many witch costume can make from them
→ Buttons → costume
→ 6 → 1
→ 18 → x
→ By using cross multiplication
∵ x × 6 = 18 × 1
∴ 6x = 18
→ Divide both sides by 6
∴ x = 3
∴ The factory can make 3 witch costume from 18 buttons
Use the same way to find the rest
∵ There are 42 buttons
→ Buttons → costume
→ 6 → 1
→ 42 → x
→ By using cross multiplication
∵ x × 6 = 42 × 1
∴ 6x = 42
→ Divide both sides by 6
∴ x = 7
∴ The factory can make 7 witch costume from 42 buttons
∵ There are 66 buttons
→ Buttons → costume
→ 6 → 1
→ 66 → x
→ By using cross multiplication
∵ x × 6 = 66 × 1
∴ 6x = 66
→ Divide both sides by 6
∴ x = 11
∴ The factory can make 11 witch costume from 66 buttons
∵ There are 84 buttons
→ Buttons → costume
→ 6 → 1
→ 84 → x
→ By using cross multiplication
∵ x × 6 = 84 × 1
∴ 6x = 84
→ Divide both sides by 6
∴ x = 14
∴ The factory can make 14 witch costume from 84 buttons
