In Example 3, the track has 6 lanes that are each 1 meter in width. a. What is the outer perimeter of the track? Round your answer to the nearest meter.
Answers
The outer perimeter of the track is 346.64 m.
What is perimeter?The perimeter of an object is given by adding the side lengths of the object.
Given that, a track has 6 lanes, each 1 meter in width, and the inner radius is 32 m, the rectangular part is having a length of 100 m,
We need to find the perimeter of the track,
We will find the circumference of the track and the perimeter of the track and then add it,
Radius of the track including the 6 lanes = 32 + 6 = 38 m
Circumference = 2 × 38 × 3.14 = 238.64 m
Perimeter = 2(32+12+10) = 108 m
The perimeter of the track = 108 + 238.64 = 346.64 m
Hence, the outer perimeter of the track is 346.64 m.

Mai started a new exercise program. On the second day, she walked 5 minutes more than on the first day. On the third day, she increased her walking time from day 2 by 20% and walked for 42 minutes. Mai drew a diagram to show her progress.
Answers
Answer:
d = 30 minutes.
day one is equal to 30 minutes
day two is equal to 35 minutes
day three is equal to 42 minutes
Explanation:
The first step is to figure out how much day 2 was worth in total.
Using the model, we can see that 5 of the boxes from day three is equal to day 2.
42/6=7.
One of the boxes equals 7 minutes.
Next we find what all 5 of them equal.
7*5=35.
Day two was worth 35 minutes in total.
The next step is to figure out what d equals. In order to do that, we need to solve the equation:
d + 5 = 35.
subtract 5 from both sides.
d = 30.
Now we know that day one/D is equal to 30 minutes.
Day one: 30 minutes
Day two: 35 minutes
Day three: 42 minutes.
Hope that this is what your looking for. Have a good day and good luck!
D = 30 minutes

Find each measure,
What is the measure of angle 1
What is the measure of angle 2
What is the measure of angle 3
(Must show equation and steps so I can understand)
Answers
Answer:
Angle 1: 137 degrees
Angle 2: 47 degrees
Angle 3: 17 degrees
Step-by-step explanation:
To find angle 1, we must look at the supplementary pair given to us. One angle is 43 degrees. If we remember, a supplementary pair adds up to 180 degrees. To find angle 1, simply subtract 43 from 180 to get 137 degrees.
Equation: 180-43
To find angle 2, we must remember that all interior angles in a triangle add up to 180 degrees. We have two angles given, a right angle (90 degrees) and 43 degrees. Subtract 43+90 from 180 to get 47 degrees.
Equation: 180-43-90
To find angle 3, use the information gained from finding angle 1 (137 degrees) and the given angle (26 degrees) and subtract both measurements from 180. Doing this gets 17 degrees.
Equation: 180-137-26.
Hope this helped!

The formula for the area of a square is length x width
There are two squares on either side of the shape and the length and width of them are 8 and 5. 8 x 5 = 40
Since there are 2 squares: 40 + 40 = 80
The formula for the area of a triangle is base x height x 1/2
Now the triangles, the base of them both is 3 and the height is 4 so you multiply 3 x 4 which = 12 and divide by 2 12/2 = 6
Since there are 2 triangles: 6 + 6 = 12
Now for the rectangle in the middle: 3 x 8 = 24
Now add all the values: 80 + 12 + 24 = 116

Phil has two rectangular prisms. The height of the second prism is times the height of the first prism. The lengths and widths of the two prisms are the same. Which best describes the volume of the second prism?
The volume is times the volume of the first prism.
The volume is 2 times the volume of the first prism.
The volume is greater than the volume of the first prism.
The volume is the same as the volume of the first prism.
Answers
Answer:
The volume of the second prism is also ten times the volume of the first prism.
Let's assume that both prisms have:
width = 3 units
height = 4 units
Prism 1 length = 5 units
Prism 2 length = 50 units
Let's solve their respective volumes to compare...
Volume of prism 1 = length * width * height
= 5 * 3 * 4
= 60 units ^3
Volume of prism 2 = 50 * 3 * 4
= 600 units ^3
Prism 2/ prism 1 = 10
That means prism 2 is ten times the volume of prism 1.

Mr. Aamodt bought a new lawn tractor for $3,350.

b. Mr. Aamodt has applied for a 2‐year loan at the bank for $3,350 to pay for the new lawn tractor. The bank will charge him 8.4% simple interest on the loan. What amount of interest will Mr. Aamodt pay on the loan? (2 points)
c. What is the total cost of Mr. Aamodt’s new lawn tractor, including the purchase price, the loan interest, and the sales tax? (2 points)
Answers
Answer:
A) 217.75 sales tax
B)281.40 he will pay on the loan
C)$3849.15 he will pay including total cost, interest, and tax
Step-by-step explanation:
A)
To find sales tax, multiply the price by its percentage. 6.5% in decimal is 0.065. 3350x0.065=217.75 for its sales tax.
B)
This is the same for loan.
3350x0.084=281.40 he will pay for loan.
C)
Now add it all up. 3350+217.75+281.40=3849.15
Answer:
The correct answers are:
a. $217.75!
b. $281.40!
c. $3,849.15!
Step-by-step explanation:
a. Find the sales tax by multiplying the price by its percentage (6.5%, 0.065 in decimal form)
3,350 x 0.065=217.75
so the sales tax is $217.75
b. This is the same as finding tax. Find the loan by multiplying the original price by the percentage (8.4%, 0.084 in decimal form).
3,350 x 0.084 = 281.40
so the loan is $281.40
c. This time, sum the original price with both the loan and sales tax.
3,350 + 217.75+ 281.40= 3849.15
so the total cost for the new tractor is $3,849.15
So there you have it. You have your answers right here. Hope this helps! Be sure to mark this as brainliest!

Sam has a credit card balance of $562.37. He paid $200 of the balance this month and plans to pay the remainder of it next month. The annual interest rate for Sam’s credit card is 17.9%, which means he will pay 1.49% interest per month.
a. If Sam makes no other payments or charges on the credit card during the next, what is the amount of interest that will be added to his next month’s bill?
b. What will be the total amount Sam will owe on his credit card next month if he plans to pay the balance in full?
Answers
Answer:
A. $5.40 PLUS original amount (362.37) =367.77
B. I think it is asking for the sum stated above. I don't know, this question is worded weird.
Step-by-step explanation:
You first find your new value. Subtract the 200$. Now you are working with $362.67 Then, multiply that by your interest rate of 0.0149: Thus giving you the amount of interest he owes. Add them together and boom!
I hope this helps, I really tried. No guarantees, have a lovely day!
Answer:
The correct answers are:
a. $367.77!
b. $195!
Step-by-step explanation:
a. 5.4 + 362.37 = 367.77
the real equation:
$562.37 - $200 = $362.37 + $5.40 = $367.77
b. Sam will owe $195 if he plans to pay the balance full.
The equation is a subtraction equation.
To find the answer. subtract the new month bill (367.77) from the original balance (562.37) and then BOOM! You got your answer.
$562.37 - $367.77 = $195
So there you have your answers. I hope this helps!
