At a boating and sport store the cost of renting a personal watercraft is $64.20 per half hour, which includes a 7% sales tax. Determine the cost of a half hour rental before tax
Answer: $60
Step-by-step explanation:
Given the following :
Total cost of renting a personal water craft = $64.20
Sales tax charged = 7%
Let the pretax cost = y
Therefore,
total cost = pretax cost + tax
$64.20 = y + 7% of y
$64.20 = y + 0.07y
$64.20 = 1.07y
y = $64.20 / 1.07
y = $60
Therefore, the rental cost of a personal watercraft for half an hour before tax is $60

PLEASE HELP NOW --- >N is a 2-digit even number. If the last two digits of N^2 is the same as N, what is the sum of digits of N?
Answer:
76.
Step-by-step explanation:
It is given that N is a 2-digit number.
Last two digits of N^2 is the same as N.
We know that, a number is even if it ends with 0,2,4,6,8.
[tex]2^2=4,4^2=16,6^2=36,8^2=64[/tex]
If 0 is in end then we get two zeros in the square of that number.
It is clear that, number should ends with 6 to get the same number at the end.
[tex]16^2=256[/tex]
[tex]26^2=676[/tex]
[tex]36^2=1296[/tex]
[tex]46^2=2116[/tex]
[tex]56^2=3136[/tex]
[tex]66^2=4356[/tex]
[tex]76^2=5776[/tex]
[tex]86^2=7396[/tex]
[tex]96^2=9216[/tex]
It is clear that last two digits of (76)^2 is the same as 76.
Therefore, the required number is 76.
Amanda is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices. Company A charges $111 and allows unlimited mileage. Company B has an initial fee of $55 and charges an additional $0.70 for every mile driven. For what mileages will Company A charge less than Company B? Use m for the number of miles driven, and solve your inequality for m.
Answer:
For mileages higher than 80 miles Company A will charge less than Company B
Step-by-step explanation:
Hi, to answer this question we have to write an inequality:
Company A charges $111 and allows unlimited mileage.
Company A =111
Company B has an initial fee of $55 and charges an additional $0.70 for every mile driven
Company B = 55+0.70m
Where m is the number of miles.
Company A has to charge less than Company B
a<b
111 < 55+0.70m
Solving for m
111-55 < 0.70 m
56 < 0.70m
56/0.70 < m
80 < m
For mileages higher than 80 miles Company A will charge less than Company B

WILL GIVE BRAILIEST! Find the mean of the data in the bar chart below. _________puppets
Answer: 2.5
Step-by-step explanation:
To find a mean, the average, we have to add everything together.
So we add 1 + 4 + 3 + 2, which is equal to 10. The next step to find the average is to divide by the total number of “things” which is the 4 puppeteers.

90% of households in a certain region have answering machines. 50% of the
households have both an answering machine and call-waiting. A household chosen at random was found to have the answering machine.
What is the probability that it also has call-waiting?
As an approximate decimal, this is 0.5556 which converts to 55.56%
======================================================
Explanation:
Let's say there are 100 households (just for the sake of simplicity). We are told that 90% of them have answering machines. So that means 90 households have answering machines. In addition, 50 households have answering machines and call waiting. Those 50 households are part of the 90 mentioned previously.
We then select a house at random. Someone tells us (or we have some kind of prior knowledge) that whichever house is selected, they have an answering machine. We can ignore the 10 households that don't have an answering machine. Out of those 90 households, 50 have both features. So 50/90 = 5/9 is the probability of getting a household with both features.
The answer would be 1/2 or 50% if we didn't have the prior knowledge of the household having an answering machine. But with this prior knowledge, the conditions change and so does the probability.
----------------
You could also compute 0.50/0.90 to get the same answer.
Which is the mean for this data? 1,2,5,5,6,6,7,8

Hope it helps <3
Answer:
[tex]\boxed{y = -(2x + 8)}[/tex]
Step-by-step explanation:
For the two lines to have infinite [tex]\infty[/tex] solutions, the two equations must be the same.
First equation : y = -2x - 8
A. y = -(2x + 8)
y = -2x - 8 correct
B. y = -2(x - 8)
y = -2x + 16 incorrect
C. y = -2(x - 4)
y = -2x + 8 incorrect
D. y = -(-2x+8)
y = 2x - 8 incorrect
y = -2x - 8 and y = -(2x + 8) when graphed are the same, they intersect at infinite points and there are infinite solutions.
1. A rectangle measures 6 cm by
4 cm. Another rectangle with adjacent
sides o on and x cm is geometrically
similar to it.
Find the two possible value of x.
Answer:
Two figures are similar if they have the same shape:
For example, two rectangles are similar if the quotient between length and wide is the same.
Now, we know that one of the rectangles is 6cm by 4cm.
The quotient of the lengths is 6cm/4cm = 3/2
Here we have a problem; you wrote
" Another rectangle with adjacent
sides o on and x cm ....."
I guess that this means:
The other triangle has one side with a measure of x cm, and the other side will have the lenght A, a constant number that you can complete after.
Now, if this new triangle is similar to the first one, then we must have;
If x > A.
x/A = 6cm/4cm = 3/2
x = (3/2)*A.
if x < A
A/x = 6cm/4cm = 3/2
x = (2/3)*A
There you have the two possible values of x, for a known A.

A zookeeper weighed an African elephant to be 9 × 103 pounds and an African lion to be 4 × 102 pounds. How many times greater is the weight of the elephant than the weight of the lion? A. 2.25x 10 B. 5 C. 13x10 D. 3.6x10
Answer:
2.25 x 10
Step-by-step explanation:
In the above question, we were given :
The weight of the Elephant = 9 × 10³ pounds
The weight of the African Lion = 4 × 10² pounds
We would compare both weights to determine which size is bigger
Weight of Elephant : Weight of Lion
9× 10³ : 4 × 10²
= 9 × 10³/4 × 10²
= 2.25 × 10¹
= 2.25 × 10
The weight of the elephant is 2.25 × 10 times greater than the weight of the lion.

Step-by-step explanation:
1. 25's perfect square would be 5. 81's would be 9. 100's is 10. 121's is 11. So therefore, that would leave you with 3.
2. 4's is 2. 9's is 3. 144 is 12. 36 is 6. Therefore, 12 is not a perfect square.
3. The perfect square of 1 is obviously 1. 16 is 4, 49 is 7, and 64 is 8. So, 27 is the odd one out.

Or= 4 ft
O r= 8 ft
O r= 16 ft
O = 32 ft
Answer:
The answer is
r =4 ftStep-by-step explanation:

EMERGENCY HELP! A steady stream of water flows into a partially-filled rectangular tank. After 6 minutes, there are 87 gallons of water in the tank. After 21 minutes, there are 222 gallons. Write an equation to represent the volume of water in the tank y after x minutes. How much water was in the tank to begin?
Answer:
[tex]y=9x+33[/tex]
33 gallons of water to begin with.
Step-by-step explanation:
So, we are essentially given two coordinates: (6,87) and (21,222). To find an equation, we will need to find the slope and y-intercept. We know it's a linear equation because it's a steady stream, meaning a constant slope.
Using the slope formula, the slope is:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}=\frac{222-87}{21-6}=135/15=9[/tex]
So, the rate at which the stream flows is 9 gallons per minute.
Now, let's find the initial amount of water. To do this, we can use point-slope form. Pick either of the two points. I'm going to use (6,87).
Point-slope form is given by:
[tex]y-y_1=m(x-x_1)[/tex]
Substitute:
[tex]y-(87)=9(x-(6))[/tex]
Distribute:
[tex]y-87=9x-54[/tex]
Therefore:
[tex]y=9x+33[/tex]
So, there were 33 gallons of water in the tank to begin with.
