Answer:
Present age of the car = 1.5 years and the tires are 0.5 years old.
Step-by-step explanation:
Let the present age of the car be x years and that of the tires be y years.
x = 3y
x = y + 1
3y = y + 1
2y = 1
y = 0.5.
x = 3*0.5 = 1.5.

Mr. Jones bought a used car. He paid $2,400 plus sales tax. The sales
tax was 8%. How much did he pay in sales tax?
Answer:
Mr. Jones paid $192 in sales tax.
Step-by-step explanation:
8 x 2400 = 19200
19200/100 = 192
jill calculates it would take 95 minutes to run 7 miles but it actually take 80 minutes what is percent of error
Answer:
15.8% = 16%
Step-by-step explanation:
The change (expected result - actual result):
95-80 = 15
Now we divide it by the expected 95 minutes and multiply by 100 to get a percentage.
15/95*100 = 15.8% = 16%
The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F:
F = 9 over 5C + 32
Which of the following formulas correctly solves for C?
C = 5F − 32 over 9
C = 5 F over 9 − 32
C = 9 over 5(F − 32)
C = 5 over 9(F − 32)
Answer: Last one is right C = 5 / 9 (F-32)
Step-by-step explanation: Solving C from equation F = (9/5)C + 32 :
1. multiply by 5 you get 5F = 9C + 160 and 5(F-32) = 9C
2. divide by 9 you get (5/9) (F-32) = C

A triangle has sides of lengths 8, 15, and 17. Is it a right triangle? Explain.
Answer:
Step-by-step explanation:
8^2 + 15^2 = ?
64 + 225 = 17^2
289 = 289
[tex]\sqrt{289} = \sqrt{289\\} \\ 17 = 17[/tex]
Convert 40% as a fraction and multiply the results by 25
40% = 40/100 = 2/5
Multiply the results by 25 :–2/5×25 = 10....
(✯ᴗ✯)Hence , the answer is 10...(◍•ᴗ•◍)A study has been done to determine to see if the level of education determines how often people move between different states in America. If a person from the survey is randomly selected , what is the probability that they lived in 2 or more states and that they have a college degree? P( 2 state or more U Degree )
0.655
0.111
0.310
0.500
Solution :
P(2 states or more | college degree)
[tex]$=\frac{\text{P( 2 states or more and college degree)}}{\text{P(college degree)}}$[/tex]
Total number of people = 58
The number of people who lived in two states or more than two states and also have a college degree = 18
Therefore,
[tex]$\text{P(2 states or more states and college degree)} = \frac{18}{58}$[/tex]
The number of people who have a college degree = 20
So, [tex]$\text{P(college degree)} = \frac{20}{58}$[/tex]
Thus,
[tex]$\text{P(2 states or more/college degree)}=\frac{\frac{18}{58}}{\frac{20}{58}}$[/tex]
[tex]$=\frac{18}{20}$[/tex]
= 0.900

1/2(n+4)=6 wat is n ?
Answer:
the correct answer is 8.
Answer:
n = 8
Step-by-step explanation:
1/2(n + 4) = 6
1/2n + 2 = 6
1/2n (+ 2 - 2) = 6 - 2
1/2n = 4
(2/1)1/2n = 4(2)
n = 8
CHECK WORK:
1/2(8 + 4) = 6
1/2(12) = 6
6 = 6

A triangle has sides with lengths 17, 12, and 9. Is the triangle right, acute, or obtuse?
Question 1 options:
A)
Can't be determined
B)
Obtuse
C)
Right
D)
Acute
9514 1404 393
Answer:
B) obtuse
Step-by-step explanation:
I like to answer these questions using a "form factor" (f) computed as ...
f = a² + b² - c² . . . . . . . where a, b, c are side lengths with c the longest
Then ...
f = 9² +12² -17² = 81 +144 -289 = -64
The negative value indicates an obtuse triangle (largest angle more than 90°).
__
f = 0 indicates a right triangle; f > 0 indicates an acute triangle.
_____
Additional comments
You may recognize that the two short sides have the ratio 9:12 = 3:4. You know a (3, 4, 5) triangle is a right triangle, so this triangle would be a right triangle if the longest side were 15. Since it is 17, you know the largest angle is more than 90°.
This "form factor" is related to the angle computation you would do to find the measure of the largest angle using the law of cosines. That angle is ...
C = arccos(f/(2ab)) = arccos(-64/216) ≈ 107.2°
Since the factor (2ab) is always positive, the sign of "f" tells you the sign of the cosine of the angle. It is negative for angles greater than 90°.

What is the surface area of the rectangular prism?
Answer: the answer is 2/8/2
Step-by-step explanation:
Rewrite each fraction with a denominator of 24 2/3 and 5/8
Answer:
2/3 = 16/24
5/8 = 15/24
Step-by-step explanation:
2/3= 16/24
5/8= 15/24
because if you multiply across [tex]\frac{2}{3}[/tex] by [tex]\frac{8}{8}[/tex] equal [tex]\frac{16}{24}[/tex]
and if you multiply across [tex]\frac{5}{8}[/tex] by [tex]\frac{3}{3}[/tex] equal [tex]\frac{14}{24}[/tex]
Suppose you want to start saving for retirement. You decide to continuously invest $5000 of your income each year in a risk-free investment with a 7% yearly interest rate compounded continuously. If y| is the value of the investment, and t| is in years. dy/dt =| Your answer should be interms of y|. You start investing at t = 0| so y(0) = 0. y(t) =| What is the size of your investment after 40 years. y(40) =|
Answer:
The size of the investment after 40 years is of $74,872.
Step-by-step explanation:
Continuous compounding:
The amount of money, in continuous compounding, after t years, is given by:
[tex]y(t) = y(0)(1+r)^t[/tex]
In which y(0) is the initial investment and r is the interest rate, as a decimal.
You decide to continuously invest $5000 of your income each year in a risk-free investment with a 7% yearly interest rate compounded continuously.
This means that [tex]y(0) = 5000, r = 0.07[/tex]. So
[tex]y(t) = y(0)(1+r)^t[/tex]
[tex]y(t) = 5000(1+0.07)^t[/tex]
[tex]y(t) = 5000(1.07)^t[/tex]
What is the size of your investment after 40 years?
This is y(40), that is, y when t = 40. So
[tex]y(t) = 5000(1.07)^t[/tex]
[tex]y(40) = 5000(1.07)^{40}[/tex]
[tex]y(40) = 74872[/tex]
The size of the investment after 40 years is of $74,872.

How many cubic inches of air does this ball hold
Answer:
This ball holds 904.78 cubic inches of air.
Step-by-step explanation:
Volume of the ball:
A ball has a spherical format. The volume of a sphere is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In which r is the radius, which is half the diameter.
Val measures the diameter of a ball as 12 inches.
This means that [tex]d = \frac{12}{2} = 6[/tex]
How many cubic inches of air does this ball hold?
[tex]V = \frac{4\pi r^3}{3}[/tex]
[tex]V = \frac{4\pi*6^3}{3}[/tex]
[tex]V = 904.78[/tex]
This ball holds 904.78 cubic inches of air.
