Find the slope on the graph?
Answers
Answer: I believe it’s 1/2
Step-by-step explanation: it cannot be a negative answer because The point on the graph is on the positive side
Answer: 2
Step-by-step explanation:
The slope of a graph is rise over run.
Find a perfect point on the graph and go to the next perfect point.
An example is:
(-2, 0) and (-1, 2)
To get from the first point to the second, you go up 2 over 1.
It’s rise (up) over run (left or right) so it’s 2/1.
2 divided by 1 is just 2.
Your slope is 2.
Hope this helps!

What is the least common multiple (LCM) of 5 and 20?
Answers
Answer:
5
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
When you make a list it will look something like this::
5-5,10,15,20

Kylie is studying the change in the water level of Sweetgum Pond as part of a summer science experiment. In the first week of June, the change in the water level was – 4 centimeters. The next week it stormed almost every day, so the water level rose 7 centimeters.
Answers
Answer:
3 centimeters
Step-by-step explanation:
The computation of the change in the water level over the first two weeks of June is shown below:
= Rise in the water level - changed in the water level
= 7 centimeters - 4 centimeters
= 3 centimeters
hence, the change in the water level is 3 centimeter and the same is to be considered

Answers
Answer:
0.75
Step-by-step explanation:
You just need to convert 3/4 into a decimal.
For example: If you get 3 out of 4 problems right on a quiz, in percent form it will be a 75%, in decimal form 0.75 because you'll move the percent sign 2 spaces to the left. That will then be a decimal if you're converting 75% to 0.75.
3 divided by 4 is also going to give you 0.75. Because, a "fraction slash" is the dividing point. So,
3/4 = 0.75

A fruit bowl contains 2 bananas, 5 oranges, and 4 apples in the simplest form, what is the ratio of apples to bananas in the fruit bowl?
Answers
Answer:
Ratio of apple to banana is 2:1
Step-by-step explanation:
To find ratio of x type of one thing and y type of other thing we divide
x by y and ratio is written as
ratio = x:y
_________________________________
Number of banana = 2
Number of apples = 4
Ratio of apple to banana = Number of apples :Number of banana
Ratio of apple to banana = 4:2
since 4 is divisible by 2 , to get the ratio in simplest form
we divide both numerator and denominator by 2
Ratio of apple to banana = 4/2:2 /2 = 2:1
Thus,
Ratio of apple to banana is 2:1

Step-by-step explanation:
First, you'll have to find the amount between the similar triangles. This is what I mean:
42.5/17 = 2.5
20/8 = 2.5
So, that means that 15(2.5) = x.

Which situation represents causation rather than correlation?
A. as the number of injured players on the sports team increases the number of fans attending the teams game increases
B. as more swimsuits are sold by department stores more sailboats are rented at the marina
C. as more people carry their umbrellas to work more people dress and heavier clothing
D. as a total number of family member increases the amount of money that the family spends on food increases
Answers
Answer: D. as a total number of family member increases the amount of money that the family spends on food increases
Step-by-step explanation:
Correlation is used to describe the 5kinf of relation between two variables whereas causation is relationship between the cause and effect.'i.e. independent variable acts like a cause to effect the dependent variable.
This can be seen only in Option D. as it is very obvious that increase in family member will increase the cost of food.
Hence, there is direct effect of number of people on food's cost.
Rest of options represents correlation but not causation .
Hence, the correction option is D.
On Saturday, Kim's softball team will be having a family picnic. Hamburger patties
are sold at the local store with 12 patties in a package. Hamburger buns, however,
are only sold in packages of 9 hamburger buns. Kim's team wants to buy the exact
same number of packages for patties and buns
What is the least number of packages of patties and hamburger buns that Kim's
team should buy to have exactly the same number of patties as hamburger buns? If a
package of hamburger patties cost $4.98 and a package of hamburger buns cost
$2.16, what was the total expense?
Answers
Answer:
See below
Step-by-step explanation:
The patties (3 packs)
12x3= 36
The buns (4 packs)
9x4= 36
cost:
3x$4.98= $14.94
4x$2.16= $8.64
Add them to equal the total cost

A department store purchases screen-printed t-shirts at a cost of $5 per shirt. They mark up the price 150% (making the selling price 250% of the store's purchase price) and put them on the sales floor. Every month that a t-shirt doesn't sell, the store reduces the selling price by 25%.Which expression shows the selling price after one monthly price reduction?
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Cost price = $5 per T - shirt
Markup = 150% or cost price
Every month which shirt doesn't sell, selling price drops by 25%
Selling price of Tshirt = (150% * $5) = $7.5
Price after 1 month = (100% - 25%) * $7.5 = $5.625
Hence, the equation could be expressed as :
Price after one month:
(1.5 * $5) - 0.75 * (1.5 * $5)
7.5 - 0.75(7.5)
Answer:
($5)(2.50) – ($5)(2.50)(0.25)
