Answer: r=5%
Step-by-step explanation:
I=Prt
I/P=Prt/P
I/P=rt
I/(P*t)=rt/t
r=I/Pt
r=63/(420*3)
r=21*3/(420*3)
r=21/420
r=1/20
r=0.05
r=0.05 * 100%
r=5%
The graph of g(x) = 3|x|+ 4 maps a person’s path from their house to school, and their path from school to a friend’s house. At what point is the school located?
Answer:
I think the school is located at (0,4).
Step-by-step explanation:
I graphed the equation in my graphing calculator and it came up with a kind of v shaped graph. If you look at the question and see that we first house to school, that would probably mean from the left side of the graph to the center (0,4). Then we go from school to friend's house, so it must be from the center to the right side of the graph. Therefore, the school must be the y intercept (0,4) as that is the center of the graph.

A cable television provider charges $75 for installation and $39.96 per month for a basic entertainment package. a satellite television provider offers free installation and charges $13.32 per month for service for each television. your neighbor subscribes to the cable provider the same month you subscribe to the satellite provider. after how many months is your neighbor's total cost the same as your total cost when you own three televisions?
The total cost will never be same for me and my neighbor.
Let us assume the number of months when cost will be equal for both me and my neighbors be x.
So, my cost of cable = Cost per month per television × number of televisions × number of months
My cost of cable = 13.32 × 3 × x
My cost of cable = 39.96x
Cost of cable for my neighbor = One time installation cost + Cost per month × number of months
(Assuming neighbor has 1 television as the number is not specified)
Cost of cable for my neighbor = 75 + 39.96 × x
Cost of cable for my neighbor = 75 + 39.96x
We need to equal the cost for both, so relating the equation -
39.96x = 75 + 39.96x
It is clear that equation can not be solved for the value of x. Hence, it can be concluded that cost of cable for me and my neighbor will never be equal. Also, my cost of cable will always be less.

There are 52 cards in a standard deck: 13 hearts, 13 clubs, 13 diamonds , and 13 spades. Timothy draws four cards at random from the deck, one of each suit. If he draws again , without replacing the four he drew, what is the probability that the next card is a heart
Answer:
[tex]\dfrac{1}{4}[/tex]
Step-by-step explanation:
Total number of cards in a standard deck = 52
Number of hearts in the deck = 13
Number of clubs in the deck = 13
Number of diamonds in the deck = 13
Number of spades in the deck = 13
Four cards are drawn at random by Timothy.
These four cards are drawn from each one of the suits.
And the cards are not replaced.
Therefore, now cards remaining in each suit:
Remaining number of hearts in the deck = 12
Remaining number of clubs in the deck = 12
Remaining number of diamonds in the deck = 12
Remaining number of spades in the deck = 12
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Here, number of favorable cases are 12 (i.e. number of hearts)
Total number of cases = 12 [tex]\times[/tex] 4 = 48
Therefore, the required probability is:
[tex]\dfrac{12}{48} = \bold{\dfrac{1}4}[/tex]
Tawnee is designing a playground in the shape of a rectangle. If Tawnee increases the length and width of the playground by a scale factor of 2
what will be the resulting effect on the perimeter of the new playground?
The perimeter of the new playground will be half the perimeter of the original playground
The perimeter of the new playground will be 1/4 the perimeter of the original playground
The perimeter of the new playground will be twice the perimeter of the original playground
O The perimeter of the new playground will be four times the perimeter of the original playground
Answer:
We conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.
Step-by-step explanation:
We know that the perimeter of a rectangle = 2(l+w)
i.e.
P = 2(l+w)
Here
'l' is the length'w' is the widthGiven that the length and width of the playground by a scale factor of 2
A scale factor of 2 means we need to multiply both length and width by 2.
i.e
P = 2× 2(l+w)
P' = 2 (2(l+w))
= 2P ∵ P = 2(l+w)
Therefore, we conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.
Answer:
I think it is the 3rd one The perimeter of the new playground will be twice the perimeter of the original playground

Snow is falling steadily in Syracuse, New York. After 2 hours, 4 inches of snow has fallen. How many inches of snow fall in 6 1/2 hours?
Answer:
12.2 inches of snow ... sorry if its incorrect
Step-by-step explanation:
Answer:
13 inches of snow would fall in 6 1/2 hours.
Step-by-step explanation:
We can apply a point system:
In zero hours, zero inches of snow would fall. (0,0)
In two hours, four inches of snow would fall. (2,4)
Since the rate of the snowfall is linear (steady), we could create a linear equation.
y = 2x, where x is the time in hours and y is the snowfall in inches.
We need to figure out what y would equal if x = 6.5 (6 1/2 hours).
Plugging in x = 6.5 in our equation:
y = 2 * 6.5
= 13

Hailey and her children went into a grocery store and she bought $10 worth of apples
and bananas. Each apple costs $1.25 and each banana costs $0,50. She bought a total
of 14 apples and bananas altogether. By following the steps below, determine the
number of apples, 2, and the number of bananas, y, that Hailey bought
Determine three ways to Have a total of 14 apples and bananas:
Cost of apples: $0.00
Cost of bananas: 50.00
Answer:
a = 4
b = 10
Step-by-step explanation:
Price of an apple $1.25
Price of a banana $0.5 0
The two equations:
10 = 1.25a + 0.5b
a + b = 14
solve for one variable
b = 14 - a
10 = 1.25a + 0.5(14-a)
10 = 1.25a+ 7 - 0.5a
10 = 0.75a + 7
0.75a = 3
a = 4
Then solve for the second
b = 14 - 4
b = 10

A rive is 10 ft wide.Two boats start to move towards each other from opposite river banks.In one minute the first boat goes 2 feet and the second one goes 1 foot.What would be the distance between the boats after 1 minute?
Answer:
The distance between the boats after 1 minute is 17 ft
Step-by-step explanation:
Here, we want to calculate the distance between the boats after 1 minute
The distance covered by the first boat after 1 minute is 2 feet while for the second it is 1 foot
So for the first boat, it has 8 ft ahead, for the second boat, it has 9 ft ahead
So the distance between the two after 1 minute will be 9 ft + 8 ft = 17 ft

Titus works at a hotel. Part of his job is to keep the complimentary pitcher of water at least half full and always with ice. When he starts his shift, the water level shows 8 gallons, or 128 cups of water. As the shift progresses, he records the level of the water every 10 minutes. After 2 hours, he uses a regression calculator to compute an equation for the decrease in water. His equation is W –0.414t + 129.549, where t is the number of minutes and W is the level of water. According to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
150 minutes
160 minutes
170 minutes
180 minutes
Answer: b. 160
Step-by-step explanation: just took the test
There are 160 minutes would the water level be less than or equal to 64 cups.
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Here, The equation we're given is,
W = -0.414t + 129.549,
which an be written as,
-0.414t + 129.549 = W.
Now, We are asked to find the amount of time it would take for the water level to be less than or equal to 64 cups.
Plugging this information in, we have:
-0.414t + 129.549 ≤ 64
To solve this, we first cancel 129.549 by subtracting from both sides:
-0.414t + 129.549 - 129.549 ≤ 64 - 129.549
-0.414t ≤ -65.549
Now divide both sides by -0.414:
-0.414t/-0.414 ≤ -65.549/-0.414
t ≥ 158.33
(When we multiply or divide both sides of an inequality by a negative number, we must flip the inequality symbol.)
t ≥ 160 minutes
Thus, There are 160 minutes would the water level be less than or equal to 64 cups.

Step-by-step explanation:
The formula for area of a triangle is 1/2bh=a with b being the base and h being the height. Base and height here are 18cm and 11cm so multiplying them gets 198, multiply by 1/2 and get 99cm^2.
for every positive integer $ k $ that divides the order of g, there exists a subgroup $ h $ of $ g $ of order $ k $.
The proof of every positive integer k that divides the order of g, there exists a subgroup h of g of order k is shown below:
What is Subgroup?A subgroup is a group nested inside another group. The subgroup test is used on subsets of a group to determine if they are subgroups. A proper subgroup is a subgroup that does not contain all of the original group, while a trivial subgroup contains only the identity.
Suppose k ∣ g ⟹n=dk:
If h(g)=⟨g⟩ is cyclic then
clearly K:=|⟨g^d⟩|=k .
Suppose now we have
1≠H≤h(g),
|H|=k and
let r>0 be the minimal natural number s.t.
g^r ∈ H , then
1=(g ^ r)^k = g^(r k)
⟹n ∣ r k ⟹ r k=ns =d ks ⟹ r= ds ⟹ s ∣ d
and from here we have
g^ r=(g^ d)^ s ∈K
Also, |H|=||K|
we get equality and thus uniqueness of K.

Let
x = cups of warm water she will need
Warm water : cups of soap
x : 2/4
Equate the two ratios
5/3 : 1/3 = x : 2/4
5/3 ÷ 1/3 = x ÷ 2/4
Cross product
5/3 * 3/1 = x * 4/2
15/3 = x * 2

1.5% as a decimal is 0.75
3/4 x 80 is 60.
4 2/3 divided by 1/2 is 1.5...
Answer:
27 = 30%
28 = 0.15
29 = 60
30 = 14
Step-by-step explanation:
When you convert a decimal to a percentage, if it is set up with "0." in front, then just swap the number behind the decimal and put it in front of the zero and add a percentage sign. When converting a percentage to a decimal, you reverse the process. Then the others are simple multiplication and division! Remember, when you're dividing a fraction, use the process "KCP" (keep change flip) where you keep the first fraction in the equation, change the division sign to a multiplication sign, and flip the next fraction. (ex. 1/2 flipped to 2/1.) Then just multiply.
