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.
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!
Which equation is a function of x?
x = 5
x = y squared + 9
x squared = y
x squared = y squared + 16
Answer:
x squared = y
Step-by-step explanation:
FunctionsThings can get more complicated, but based on the examples given, for an equation to be a function of x, it must have a single y, where the y is not raised to a power.
Option 1: x=5
This equation doesn't have a y, so it isn't a function of x.
Option 2: x = y squared + 9
This equation has y raised to a power, so it isn't a function of x
Option 3: x squared = y
This equation has a y, and the y isn't raised to a power. This is a function of x.
Option 4: x squared = y squared + 16
This equation has y raised to a power, so it isn't a function of x
Determining functions graphicallyIf the equations are graphed, the graphs must pass a vertical line test (a vertical line drawn anywhere should not intersect the graph more than once).
Option 1: x=5
x=5 represents a vertical line, so it fails the vertical line test (the vertical line would overlap and intersect it infinitely many times).
Option 2: x = y squared + 9
x = y squared + 9 is a sideways parabola. A vertical line will cross it twice in several places
Option 3: x squared = y
x squared = y is a parabola that opens upward. It will pass the vertical line test
Option 4: x squared = y squared + 16
x squared = y squared + 16 is a hyperbola (fancy graph shape) that won't pass the vertical line test.
Mr. Aamodt bought a new lawn tractor for $3,350.
a. The state sales tax on the lawn tractor purchase will be 6.5%. How much state sales tax will Mr. Aamodt pay on the tractor? (2 points)
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)
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!

EXPERT HELP: Some species can reproduce sexually or asexually. In which two situations is sexual reproduction advantageous?
A. When no individuals of the same species are available for mating
B. When many individuals of the same species are available for
mating.
C. When the individuals live in a stable environment in which they
thrive.
D. When the individuals live in an environment that suddenly
changes.
answer: B,C
Step-by-step explanation:
to be able to reproduce sexually you need enough of the same species to mate with. A says no individuals to reproduce with but for that it would be better if they were asexual. D says they change living environment and that usually changes the amount of same species animals that are around to reproduce with.

PLEASE HELP!

Answer:
Given : The high school stadium contains a track that surrounds a soccer field. The soccer field is 100 yards long and 70 yards wide.
The school decided to cover the semicircles with grass to create a space for stretching and other activities.
To Find: area of one of the semicircles at either end of the track
How many square yards of grass will the school need to cover the entire circle?
Solution:
Diameter of semicircle = 70 yards
Radius of semicircle = 70/2 = 35 yards
Area of semicircle at one end = (1/2)πr²
= (1/2)(22/7)35²
= 1,925 sq yards
area of one of the semicircles at either end of the track = 1,925 sq yards
square yards of grass will the school need to cover the entire circle
= 2 x 1,925
= 3850 sq yards
distance around one of the semicircles at either end of the soccer field = πr = (22/7) 35 = 110 yards
distance around the inner lane of the track = 100 + 100 + 110 + 110
= 420 yards

If 120% of a is equal to 80% of b, then what is the value of a+b in terms of a and b?
Answer:
120/100 a = 80/100 b
12/10 a = 8/10 b
10 (12/10) a = 10 (8/10) b
12a= 8b
3a= 2b
a+b in terms of a
b = 3/2×a
a+ 3/2×a = 5/2×a
a+b in terms of b
a = 2/3×b
b + 2/3.b = 5/3×b
Two glass containers are shown. Both are right rectangular prisms. Container 1 is filled with water and Container 2 is empty.
Amalia wants to pour all of the water from Container 1 into Container 2. What must the height of Container 2 be in order for it to hold exactly the same amount of water as Container 1?
Note: Find the volume of container 1 first. Then use the same volume to solve for the missing height of container 2.
Show your work and write your answer on the line in the space below.
9514 1404 393
Answer:
18 in
Step-by-step explanation:
The volume of each container is the product of its dimensions:
V = LWH
We can let h represent the unknown height of Container 2. The volumes are equal when ...
32·18·12 = 24·16·h
(32·12·18)/(16·24) = h =18 . . . . . divide by the coefficient of h, simplify
The missing height of Container 2 is 18 inches.

A sports apparel company surveyed the market about the size of T-shirts people most frequently buy, small, medium, large, or extra-large. The
table shows the survey results.
T-Shirt Size Number of responses
small
11
mediurn
37
large
83
extra-large
19
To help Its sales, the company should focus on producing size
T-shirts. Approximately % of T-shirts the company
makes should be medium and large T-shirts to match the market preference. If the total number of T-shirts sold in a month is 45,000,
of these will likely be size small.
Answer:
To help Its sales, the company should focus on producing Large
T-shirts. Approximately 80% of T-shirts the company
makes should be medium and large T-shirts to match the market preference. If the total number of T-shirts sold in a month is 45,000, 3,300
of these will likely be size small.
Step-by-step explanation:
In the survey, Large t-shirts are most frequently bought so they should be the primary focus if the company is trying to make more money.
To find the percentage of shirts that the medium and large shirts make up, first you find the total amount of shirts (11+37+83+19=150), then you will find how many mediuma and large shirts (37+83=120). Percentage is (120/150)*100=80%
To find the number of small shirts you can set up a proportion.
[tex]\frac{11}{150} =\frac{x}{45,000}[/tex], then cross multiply
150x=11*45,000
150x=495,000
x=3,300
