Answer: 2:3
Step-by-step explanation:
First list out the factors for 32 and 48
32- 1, 2, 4, 8, 16, 32
48- 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The greatest factor they have in common is 16. So, divide both numbers by 16 to get the simplest form of the ratio.

Answer:
y=ax+b
a=-0.6020457867
b=-2.256697516 <------- There is your value for b, which is the answer to the problem.
You can use these values for a and b to generate an equation in slope-intercept form, which you can then enter under Y= and view the graph.
Step-by-step explanation:
The value of y is multiplied by 2 each time when the value of x increases by 1 and this can be determined by using the arithmetic operations.
What is an mathematical expression?Using operations like addition, subtraction, multiplication, and division, a mathematical expression is defined as a group of numerical variables and functions.
Given that,
Table -- x y
1 20
2 40
3 80
4 160
5 320
The following steps can be used in order to describe how the y values are changed over each interval:
Step 1 - When value of (x = 1) and the value of (y = 20).
Step 2 - When value of (x = 2) and the value of (y = 40).
Step 3 - When value of (x = 3) and the value of (y = 80).
Step 4 - When value of (x = 4) and the value of (y = 160).
Step 5 - From the above steps, it can be concluded that the value of y is multiplied by 2 each time when the value of x increases by 1.

Jose rides his bike for 5 minutes to travel 8 blocks he rides for 10 minutes to travel 16 blocks which value will complete the table
Using the unit rate, the missing values that completes the table are:
A = 5; B = 15; C = 40
How to Find Unit Rate?Unit rate (m) = change in y/change in x.
5 minutes for 8 Blocks (5, 8) and 10 minutes for 16 blocks (10, 16)are given.
Unit rate (m) = (16 - 8)/(10 - 5) = 8/5
An equation that will define the function is, y = 8/5x. Use it to complete the table.
Find A (y) when x is 5:
y = 8/5(5) = 8
The value of A is: 5
Find B (x) when y is 24:
24 = 8/5(x)
5(24) = 8x
120 = 8x
120/8 = x
15 = x
The value of B is: 15
Find A (y) when x is 25:

Assessing the given Venn diagram and the data related to it, we can answer the required question:
Q1. How many people were surveyed = 86.
Q2. What is the probability that a customer chosen at random:
a) takes salt P(S) = 46/85.
b) takes both salt and vinegar P(S ∩ V) = 13/85.
c) takes salt or vinegar or both P(S ∪ V) = 66/85.
The number of people who take salt chips n(S) = 46.
The number of people who take vinegar chips n(V) = 33.
The number of people who takes both n(S ∩ V) = 13.
The number of people who take neither n((S ∪ V)') = 19.
Therefore, the total number of people surveyed n(U) = n(S) + n(V) - n(S ∩ V) + n((S ∪ V)') = 46 + 33 - 13 + 19 = 85.
The number of people who takes salt or vinegar or both n(S ∪ V) = n(U) - n((S ∪ V)') = 85 - 19 = 66.
The probability that a customer chosen at random takes salt P(S) = n(S)/n(U) = 46/85.
The probability that a customer chosen at random takes both salt and vinegar P(S ∩ V) = n(S ∩ V)/n(U) = 13/85.

What is m∠M? I don't exactly remember how to do this type on problem...
Answer:
m∠M=98º
Step-by-step explanation
Sum of interior angles;
3x-16+x+6+x = 180
5x = 180-6+16
5x = 190
x = 38º
Angle M;
m<M= 3x - 16 = 3(38)-16= 98º
m∠M=98º
Answer:
<M = 98
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
< M + < N + < O = 180
3x-16 + x + x+6 = 180
Combine like terms
5x - 10 = 180
Add 10 to each side
5x-10 + 10 = 180+10
5x = 190
Divide by 5
5x/5 = 190/5
x=38
We want to find <M
<M = 3x-16 = 3*38 -16 = 114-16 =98

-6 = -1/6
10 = 1/10
Step-by-step explanation:
an additive inverse is a number you must add to another number to get 0
(think of it as the negative version of the number)
{but WHY? In math, you can imagine comparing numbers on a number line. If we are finding the opposite of a number, we want to find the same distance from 0, but on the opposite side of 0. So, 2 would be two to the right of 0, -2 would be two to the left of 0}
-2 + 2 = 0
18 - 18 = 0
-30 + 30 = 0
2/5 - 2/5 = 0
a multiplicative inverse is a number that you multiply by another number to get 1.
We are finding the "reciprocal" of a number; you are essentially flipping it as a fraction
(reciprocal of 2 = 1/2 {remember, 2 is the same thing as 2/1 } ; reciprocal of 1 / 8 = 8)
note: reciprocal is being used interchangeably with multiplicative inverse here
8/9 · 9/8 = 1

A car manufacturer has parked some new cars in 2 car parks.In the first car park there are 60 cars in the ratio 1 red car for every 2 blue cars and 3 silver cars.In the second car park there are 80 cars in the ratio 2 blue cars for every 3 red cars and 5 silver cars.
11. How many red cars are there altogether?
12.How many blue cars are there altogether?
13.How many silver cars are there together?
The total number of red cars is 34, the total number of blue cars is 36, and the total number of silver cars is 70.
How do we solve ratio problems?
The ratio problems can be solved as follows:
11. The total number of red cars can be calculated as follows:
Number of red car in the first car park = (1 / (1 + 2 + 3)) * 60 = 10
Number of red car in the second car park = (3 / (2 + 3 + 5)) * 80 = 24
Total number of red cars = 10 + 24 = 34
12. The total number of blue cars can be calculated as follows:
Number of blue car in the first car park = (2 / (1 + 2 + 3)) * 60 = 20
Number of blue car in the second car park = (2 / (2 + 3 + 5)) * 80 = 16
Total number of blue cars = 20 + 16 = 36
13. The total number of silver cars can be calculated as follows:
Number of silver car in the first car park = (3 / (1 + 2 + 3)) * 60 = 30
Number of silver car in the second car park = (5 / (2 + 3 + 5)) * 80 = 40
