If the speed limit is 80 kilometers per hour, and Elena’s mom was driving 75 miles per hour, was she speeding? By how much?

If The Speed Limit Is 80 Kilometers Per Hour, And Elenas Mom Was Driving 75 Miles Per Hour, Was She Speeding?

Answers

Answer 1
She is speeding

First you need to converted miles into km as she was driving with miles but our speed limit is km so to maintain the balance we have to convert the measurements into one unit

Speed limit was 80km
She was driving 75 miles
We know,
1 mile = 1.609 km
So 75 * 1.609 = 120.675 km

So speeding = (120.675 - 80)
= 40.675

Therefore, she was over 40 km speed limit

A circle is the same as 360°. You can divide a circle into smaller portions. A part of a circle is called an arc and an arc is named according to its angle.
A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.
Example
An investigation was made in Mathplanet high school to investigate what color of jeans was the most common among the students. This circle graph shows how many percent of the school had a certain color. We now want to know how many angles each percentage corresponds to.
Pie 01
To find out the number of degrees for each arc or section in the graph we multiply the percentage by 360°.
Blue57%:0.57⋅360∘=205.2∘

Black19%:0.19⋅360∘=68.4∘

Beige12%:0.12⋅360∘=43.2∘

Grey8%:0.08⋅360∘=28.8∘

Red4%:0.04⋅360∘=14.4∘

When we want to draw a circle graph by ourselves we need to rewrite the percentages for each category into degrees of a circle and then use a protractor to make the graph.

1. Semir, Sarah, and SungSo decided to raise money for a local homeless shelter by working in a local deli. The deli agreed to donate to the shelter a portion of the profits from each meal the three sold. Semir sold 3 times as many meals as Sarah. SungSo sold 2 more meals than Sarah.
a.Write an expression for the number of meals that each sold.

b. If Sarah sold 24 meals, how many meals did Semir and SungSo each sell?

c. How many meals did the three sell in all? Explain how to use the commutative property and the associative property of addition to make finding the sum easier.

2. The three decided to participate in a walkathon to raise additional money for the shelter. Sarah walked 5 miles less than twice the number of miles that Semir walked. They each collected $18 in pledges for every mile they walked.

a.Let n represent the number of miles Semir walked. Write an expression for the number of miles Sarah walked and an expression for the amount of money Sarah collected in pledges.

b.Write and solve an equation to find how many miles Semir walked if Sarah collected $450 in pledges.

c. How many miles did Sarah walk?

d. SungSo also collected $18 in pledges for every mile he walked. In addition, his grandmother gave him a $72 donation. He collected the same amount of money as Sarah did. Write and solve an equation to find the number of miles SungSo walked.

3. Write a memo to the director of the shelter describing the total donation the three friends are sending and how it was raised. Be sure to include how much each student raised individually.

Answers

Answer:

Sarah=S

SungSo=U

Semir=E

1.

A. (2+S)+(3s)+S

B. SungSo sold 26 meals and Semir sold 72 meals.

C. In total the meals sold are 122 meals. The commutative property plays a role in this problem since it doesn't matter which order you add them in. The associative property also shows that it doesn't matter in which way you group the addends.

2.

A. (2n-5)*18

B. (450/18-5)/2=10

C. 25 miles

D. (25*18-72)/18=21

3. In total, SungSo, Sarah, and Semir have raised $1,080 and sold 122 meals in total. SungSo sold 26 meals, Semir sold 72 meals, and Sarah sold 24 meals. SungSo raised $378, plus the $72 donation which brings the money to $450, Semir raised $180, and Sarah raised $450.

Step-by-step explanation:

1.

A. The equation is (2+S)+(3s)+S since Sarah=S, SungSo sold 2 more meals than Sarah, and Semir sold 3 times as many meals as Sarah.

B. SungSo sold 26 meals and Semir sold 72 meals because if you plug it in with the equations, (2+24)=26 meals for SungSo and (3*24)=72 meals for Semir.

C. In total the meals sold are 122 meals since (2+24)+(3*24)+24=122. The commutative property plays a role in this problem since it doesn't matter which order you add them in. The associative property also shows that it doesn't matter in which way you group the addends.

2.

A. The answer is (2n-5)*18 because Sarah walked 5 miles less than twice the number of miles that Semir walked, n.

B. The answer is (450/18-5)/2=10 because then you would need to use the same equation as you used in part A, but use it inversely since now you have how much Sarah collected instead of how many miles Semir walked.

C. Sarah walked 25 miles since she earns $18 per mile and she earned $450, so 450/18=25.

D. The answer is (450-72)/18=21 because he collected the same amount of money as Sarah which is 450. He also recieve a donation of $72 from his Grandmother, so you would subtract that and then divide it by 18 to find how many miles he walked.

3. In total, SungSo, Sarah, and Semir have raised $1,080 and sold 122 meals in total. SungSo sold 26 meals, Semir sold 72 meals, and Sarah sold 24 meals. SungSo raised $378, plus the $72 donation which brings the money to $450, Semir raised $180, and Sarah raised $450.

Answer:

$1,169.30

Step-by-step explanation:

The answer is $1,169.30 since 621.60-600=21.60, meaning that in the past 4 years, Chelsea has gained $21.60. Then you would do 21.60/4 to find how much per year, which would get you $5.40. Then you need to find the interest rate by doing 5.40/600 since she started out with 600. 5.40/600=0.009. Then you would turn it into percentage by multiplying it by 100, to get 0.9%. Now, since she's deposited $1,100 instead, you would do 0.9*1,100, and then you would get 990, then you would have to divide it by 100 and get $9.90. That means she gains $9.90 per year. Since she'll have it for 7 years, you need to do 9.90*7=63.90. Then you would add it to 1,100 to get $1,169.30

To make it short your answer would be 1,169.30

A circular hot spring has a diameter of 96 meters. Over time, the diameter of the spring decreases by 8 meters. By how many square meters does the area of the hot spring decrease? Use 3.14 for pi.

about (BLANK) m2

Answers

The area decreases by 1155.52 square meters

Step-by-step explanation:

What we must do is calculate the area before and after making the diameter cut.

The area of a circle is equal to:

a = pi * r ^ 2

now the diameter is equal to:

d = 2 * r

therefore r,

r = d / 2

before the cut would be

r = 96/2

r = 48

replacing in the area formula

a1 = 3.14 * 48 ^ 2

a1 = 7234.56 square meters.

after cutting the diameter decreases by 8, that is, 96 - 8 = 88, calculating the radius would be:

r = 88/2

r = 44

now calculating the new area would be:

a2 = 3.14 * 44 ^ 2

a2 = 6079.04 square meters.

now we calculate the difference

a1 - a2 = 7234.56 - 6079.04

= 1155.52 square meters

means that the area decreases by 1155.52 square meters
