Answer:
1/3 hour per mile3 miles per hourStep-by-step explanation:
Time per mile can be found by dividing hours by miles:
(1/8 h)/(3/8 mi) = 1/3 h/mi
It will take him 1/3 hour to run 1 mile.
__
Miles per hour can be found by dividing miles by hours (or by finding the reciprocal of the above value):
(3/8 mi)/(1/8 h) = 3/1 mi/h = 3 mi/h
He could run 3 miles in one hour.

9325 cm is equal to how many meters?
Answer:
93.25
Step-by-step explanation:
One meter = 100 cm
9300 divided by 100 = 93 + 0.25 = 93.25
The conversion of the given measurement of 9325 cm to meters is gotten as; 93.25 meters
How to convert Centimeter to meter?There are different units in mathematics to convert. However, in this case, we want to convert centimeters to meters.
Now, the conversion rate here is;
100cm = 1m
Thus, to convert 9325 cm to meters we will just divide it by 100.
Thus;
9325 cm = 9325/100 = 93.25 meters

PLEASE HELP!!!! A boat can travel at an average speed of 10 miles per hour in still water. Traveling with the current, it can travel 6 miles in the same amount of time it takes to travel 4 miles upstream.
Answer:
2 mphStep-by-step explanation:
Let the speed of current be x
Speed of the boat in same direction as current is
10 + xSpeed against the current is
10 - xBased on the given we get the equation for time
6/(10 + x) = 4/(10 - x)Solving for x
6(10 - x) = 4(10 + x)60 - 6x = 40 + 4x6x + 4x = 60 - 4010x = 20x = 2The answer is 2 mph
Answer:
6/(10-x) = 4/(10+x)

Which expression is equivalent to 5y^3/(5y)^-2?
a. y^5
b. y^6
c. 125y^3
d. 125y^5
Answer:
I think the answer is D.
Step-by-step explanation:
[tex] \frac{ {5y}^{3} }{ {(5y)}^{ - 2} } \\ = \frac{ {5y}^{3} }{ {(\frac{1}{5y})}^{2} } \\ = {5y}^{3} \times {25y}^{2} \\ = 125 {y}^{5} [/tex]
Davis hit a baseball from a height of 3 feet above the ground at an angle of 24 degrees with the horizontal at an initial velocity of 110 feet per second. How far will the ball travel before it hits the ground?
8. Write a parametric equation for the flight of the ball.
9. Find the maximum height of the ball.
10. How many feet did the ball travel horizontally before it hit the ground?
Answer:
The ball travel horizontally before it hit the ground is 34.22 feet.
Step-by-step explanation:
Given that,
Height = 3 feet
Angle = 24 °
Initial velocity = 110 feet/s
We need to write a parametric equation for the flight of the ball
Using given data
[tex]r(t)=u\cos\theta\times t\hat{i}+(h+(u\sin\theta)t-\dfrac{1}{2}gt^2)\hat{j}[/tex]
Put the value into the formula
[tex]r(t)=110\cos24\times t\ i+(3+110\sin24\times t-\dfrac{1}{2}32t^2)j[/tex]
[tex]r(t)=100.4t(i)+(3+44.7t-16t^2)j[/tex]
Now, on differentiating w.r.to t
[tex]v(t)=100.4i+(44.7-32t)j[/tex]....(I)
We need to calculate the time
Using equation (I)
If y'(t)=0, then the ball will be at maximum height
So, [tex]y'(t)=44.7-32t[/tex]
Put the value of y'(t)
[tex]44.7-32t=0[/tex]
[tex]t=\dfrac{44.7}{32}[/tex]
[tex]t=1.4\ sec[/tex]
We need to calculate the maximum height
Using equation of motion
[tex]y(t)=h+ut-\dfrac{1}{2}gt^2[/tex]
Put the value into the formula
[tex]y(1.4)=3+44.7\times1.4-16\times(1.4)^2[/tex]
[tex]y(1.4)=34.22\ feet[/tex]
Hence, The ball travel horizontally before it hit the ground is 34.22 feet.
What is the rate of change of the function whose graph is a line passing through (3, 5) and (−1, 5)?
9514 1404 393
Answer:
zero
Step-by-step explanation:
The y-coordinates of the two points are the same, so the line through them is a horizontal line. There is no vertical change for any amount of horizontal change. The "rate of change" is 0.

The perimeter of a trianglular pool is 36
yards the length of two sides or 10 yards and 15 yards how long is the third side
Answer:
11 yard
Step-by-step explanation:
Let the 3rd side be 'a'.
Perimeter = 36
=> sum of sides = 36
=> 10 + 15 + a = 36
=> 25 + a = 36
=> a = 36 - 25
=> a = 11

The ratio of yes votes to no votes was 4 to 7. If there were 3824 yes votes, what was the total number of votes?
Answer:
10,516
Step-by-step explanation:
you can do it different ways but I found the scale factor by dividing 4 into 7 which gives you 1.75 you then multiply that by the amount of yes votes (3824x1.75) which gives you 6692 and then you add that to the amount of yes votes which gives you the answer, 10516 - the total number of votes!
Divide total yes votes by the ratio for yes then multiply by the ratio for no:
3824 /4 = 956
956 x 7 = 6692 total number of no votes
total number of votes = 6692 + 3824 = 10,516
May can do 936 jumping jacks in
6 minutes. Heather can do 616
jumping jacks in 4 minutes. Who
can do the most jumping jacks
per minute?
please help meeee !
Answer:
May
Step-by-step explanation:
936 ÷ 6 = 156
616 ÷ 4 = 154
Answer: May
May can do 936 jumping jacks in
6 minutes. Heather can do 616
jumping jacks in 4 minutes. Who
can do the most jumping jacks
per minute?
If you were to divide 936 by 6, you would get 156. Then, divide 616 by 4, and you would get 154. This gives you how many jumping jacks each of them do in one minute. The answer to May’s equation was more than Hather’s equation, so May can do more jumping jacks than Heather.
Often we need to use exponents to correctly model the variation in situations:
The volume of a cylinder varies jointly with the square of its radius and its height. Its
general equation looks like V = kr’h where k= some constant number for all cylinders
and V, rand h are variables representing volume, radius and height, respectively. When
the radius is 3 cm and height is 5 cm, the cylinder has a volume of 141.3 cm. Find the
volume when the radius is 6 cm and the height is 10 cm.
Answer:
V = 1130.4 cm³
Step-by-step explanation:
Given that V varies jointly with r² and h then the equation relating them is
V = kr²h ← k is the constant of variation
To find k use the condition when r = 3 and h = 5 then V = 141.3 , then
141.3 = k × 3² × 5 = 45k ( divide both sides by 45 )
k = 3.14 ← note approximation for π
V = 3.14r²h ← equation of variation
When r = 6 and h = 10, then
V = 3.14 × 6² × 10 = 3.14 × 36 × 10 = 1130.4 cm³

PLEASE HELP WITH THIS
Answer:
B
Step-by-step explanation:
The question can be written is
5^x = 75
Now take the log of both sides.
log(5x) = log(75) Bring the x outside the brackets
x log(5) = log(75) Divide by log 5
x = log(75)/log(5)
log 75 = 1.8751
log 5 = .8990
x = 1.8751/.8990 = 2.6826
Answer:
(b) 2.68
Step-by-step explanation:
Your question has a link to a suitable calculator. All you need to do is make use of it. It tells you log₅(75) ≈ 2.68.
__
Other ways to look at the problem
If you recall that a logarithm represents an exponent of the base, you can ask yourself, what power 5 must be raised to in order to get 75. You know that 5^2 = 25, and 5^3 = 125, so the power will have to be between 2 and 3. There is only one answer choice in that range: 2.68.
__
The rules of logarithms let you rewrite the given expression as ...
log₅(75) = log₅(3×5²) = log₅(3) +2·log₅(5) = log₅(3) +2
The log₅ of any number between 1 and 5 will be a positive fraction, so this sum must be between 2 and 3.

You spend 15 minutes . You then spend two hours reading email. Write the ratio of the amount of time spent watching television to the amount of time spent reading email as a fraction in simplest form.
Answer:
1:8
Step-by-step explanation:
The ratio for watching tv, to reading email is 15:120 (because two hours equals 120 min.).I then divided both sides by three to get 5:40. I then divided that ratio by 5 to get 1:8, which is the simplest form.
