Find the slope from the graph.
-1/2
-4/3
3/4
-3/4
Answers
Answer: 3/4
Step-by-step explanation:
To find the slope from the graph, we need to look at the rise and run of the line. The slope is the ratio of the vertical change (rise) to the horizontal change (run).
Let's analyze the given options:
-1/2: This means that for every 2 units the line moves horizontally, it moves down 1 unit vertically.
-4/3: This means that for every 3 units the line moves horizontally, it moves down 4 units vertically.
3/4: This means that for every 4 units the line moves horizontally, it moves up 3 units vertically.
-3/4: This means that for every 4 units the line moves horizontally, it moves down 3 units vertically.
So, from the given options, the slope is 3/4. This indicates that for every 4 units the line moves horizontally, it moves up 3 units vertically.
Remember, the slope of a line is a measure of how steep the line is. It tells us how much the line is rising or falling as we move along the x-axis.
Use the slope formula to solve this question:
The slope formula is as followed:
y₂ - y₁
x₂ - x₁
where (x₁, y₁) and (x₂, y₂) are two sets of coordinates
Pick the two points on the line:
(0, 5) (4, 2)Now, plug them into the equation and solve:
y₂ - y₁
x₂ - x₁
[tex]\frac{2-5}{4-0}[/tex] = [tex]\frac{-3}{4}[/tex]
The slope of the line is -3/4
Angles X and Y are supplementary. Angle X measures 126.25° and angle Y measures (m − 10)°. Find m∠Y.
53.75°
63.75°
107.5°
117.5°
Answers
The measure of angle y is 53.75°. Therefore, option A is the correct answer.
Given that, ∠x=126.25° and ∠y=(m − 10)°.
What are supplementary angles?Supplementary angles refer to the pair of angles that always sum up to 180°. These two angles are called supplements of each other.
Here,
∠x + ∠y = 180°
⇒ 126.25°+(m − 10)° = 180°
⇒ (m − 10)° = 180°-126.25°
⇒ (m − 10)° = 53.75
⇒ m = 63.75°
So, ∠y=(m − 10)°= 53.75°
The measure of angle y is 53.75°. Therefore, option A is the correct answer.

Step-by-step explanation:
we know that
The perimeter of a rectangle is equal to
P=2(L+W)
we know that
L=7.6 m
P < 28 m
substitute
2(7.6 + W) < 28
solve for W
(7.6 + W) <14
W <14 - 7.6

Fredrick and Kate have 17 1/3 cups of flour. They want to make loaves of banana bread for a bake sale. Fredrick has a recipe that calls for 1 5/8 cups of flour
Kate has a recipe that calls for 1 3/4 cups of flour. Select the statements that are true.
Answers
Answer:
Fredrick's recipe will make 10 whole loaves & There will be less flour left over if Fredricks recipe is used
Step-by-step explanation:
Fredrick's recipe
17 1/3 ÷ 1 5/8 = 10 2/3
Kate's recipe
17 1/3 ÷ 1 3/4 = 9 19/21
So Fredrick's recipe will make 10 whole loaves
9 19/21 is less than 10 2/3 so there will be less flour left over if Fredricks recipe is used

The diameter of a bike wheel is 27 inches. If the wheel makes 15 complete rotations, how far does the bike travel to the nearest whole inch?
Answers
Answer:
1271.7 inches.
Step-by-step explanation:
We know the diameter of the bike wheel is 27.
Radius of the wheel: 13.5 in.
The circumference of the wheel: 84.78
So let's say the distance traveled in 1 rotation. Based of on the circumference, we know that 1 rotation is 84.78.
So if the distance was traveled in 15 rotations we need to multiply 84.78 to 15. 84.78 x 15 = 1271.7.

Jorge says there are 198 inches in 5.5 yards. Is he correct. Explain your answer. Show your work.
Answers
Answer: yes, he is correct
Step-by-step explanation:
since there is 36 inches in 1 yard, we will multiply 5.5 by 36 to find out how many inches are in 5.5 yards. since 5.5 yardsx36 inches in one yard=198 inches, Jorge is correct.
Yes, he is correct, because if in one yard is 36 inches, and half a yard is 18 inches, if you multiply 36 by 5, you get 180. Then add the half yard of 18 to have 5.5 yards, or 198 inches. :)

The percentage is the part/whole x 100 so we need to find the whole, which is 189+36=225 and the percentage is the amount of people who voted which is 189 and the part/whole x 100 is 189/225 = 0.84 0.84x100=84=84%

No, they should not plan for the skate park because the sample had about 46.4% people vote no.

Yes, they should plan for the skate park because the sample had about 46.4% people vote yes.
Yes, they should plan for the skate park because the sample had about 53.6% people vote yes.
Answers
Yes, they should plan for the skate park because the sample had about 46.4% people vote yes. Thus, option C is correct.
What is a sample?A sample is characterized as a more workable and compact version of a bigger group. a smaller population that possesses the traits of a bigger group. Since the population size exceeds the threshold big to accommodate all those who participated in the test, a subsection of the population is utilised in statistical analysis.
The details that are given:
the needed percentage to build a skateboard = 40 %
The total number of voters = 125
The people who responded yes = 58
The percentage of the people who voted will be:
= 58/125 * 100
= 46.4 %
As the value of 46.4 % > 40%, the individual should be able to vote.
Therefore, option C is correct.
