Solve for h in the mathematical formula V=pi r^(2)h
Answers
Answer:
[tex]\frac{V}{\pi r^{2} }[/tex] = h
Step-by-step explanation:
Lets try and get everything we can away from h.
V = [tex]\pi[/tex][tex]r^{2} h[/tex]
Divide [tex]\pi[/tex][tex]r^{2}[/tex] from both sides of the equation.
Now we end up with:

Answers
Answer:
The answer is A 40 cars
Step-by-step explanation:
We can see by dividing 30 by 45 you get 0.66667 repeating. If you then multiply 0.66667 by 60 (There are 60 minutes in an hour) You get 40.02. This rounds down to 40. Please mark me brainliest, and have a tremendous day!

3. Fifteen bicycles are produced each hour at the
Speedy Bike Works. Show that the relationship
between the number of bikes produced and the
number of hours is a proportional relationship.
Then write an equation for the relationship.
Answers
Answer:
The equation is: y = 15·x
Step-by-step explanation:
It is provided that at the Speedy Bike Works, 15 bicycles are produced each hour.
Consider the table below.
Number of Hours: 1 3 6 10
Number of Bicycles Produced: 15 45 90 150
Compute the ratio of number of bicycles produced and number of hours for every data above as follows:
[tex]\text{1 hour}=\frac{15}{1}=15:1\\\\\text{3 hour}=\frac{45}{3}=\frac{15}{1}=15:1\\\\\text{6 hour}=\frac{90}{6}=\frac{15}{1}=15:1\\\\\text{10 hour}=\frac{150}{10}=\frac{15}{1}=15:1[/tex]
The ratio of the number of bicycles produced and number of hours is same for every data value.
Thus, the relationship between the number of bicycles produced and number of hours is proportional.
The equation for the relationship is:
y = 15·x
y = number of bicycles produced
x = number of hours

10 1/2 divided by 3/8 = 12/2 times 8/3= 9/6 is this ture?

KCF (keep, change the sign, flip the fraction)
·21/2×8/3=168/6
168/6=28
12/2×8/3=16
therefore they are not equal so it is not true
Hope this helped ;)
Answer:
well lets solve this:
10 1/2-->21/10
21/10 dvided by 3/8-------> to divide fractions we do this: 10/21 x 3/8 (swap the denom and num of the firs fraction then multiply by the sec)
10/21x3/8=30/168 = 3/56
12/2 x 8/3 = 6x 8/3= 6/1x8/3=48/3
48/3 simplified is 16/1 =16
3/56x16/1 = 48/56
48/56=24/28=12/14=6/7

A truck can be rented from Company A for $150 a day plus $0.40 per mile. Company B charges $80 a day plus $0.90 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answers
Answer:
140 miles
Step-by-step explanation:
Let
Number of miles = m
Total cost = fixed cost + variable cost
Company A = $150 + $0.40m
Company B = $80 + $0.90m
Equate company A and company B equation
Company A = Company B
$150 + $0.40m = $80 + $0.90m
Collect like terms
150 - 80 = 0.90m - 0.40m
70 = 0.50m
m = 70 / 0.50
= 140
m = 140 miles
The number of miles in a day at which the rental costs for Company A and Company B are the same is 140 miles

The cost C , in £, of a monthly phone contract is made up of the fixed line rental L , in £, and the price P , in £ ,of the calls made. Enter a formula for the cost and, enter the cost if the line rental is £10 and the price of calls made is £28.
Answers
Answer:
C = L + P
C = £38
Step-by-step explanation:
Given that :
Cost (C) is given by :
Sum of fixed line rental (L) ; price (P) of calls made.
Hence,
Cost formula;
C = L + P
Cost if the line rental is £10 and the price of calls made is £28.
C = L + P
If L = £10 ; P = £28
C = £10 + £28
C = £38
The local furniture store pays $300 for a dining room table and sells it with a 40% markup.
What is the selling price of the dining room table?
Answers
Answer:
$420
Step-by-step explanation:
The wholesale price is $300 and the markup is 40% of that, or
0.40($300) = $120
and so the selling price is $300 + $120 = $420
An easier way to calculate this is to multiply $300 by (1.00 + 0.40), or (1.40), which again comes out to $420.
Answer:
$420!

Solve for missing angle
Answers
Answer:
so the exterior angle 152 is made from the interior angle being subtracted from 180. we can also subtract 152 from 180 to find the interior angle. 180-152=28 the inside of a triangle is a total of 180 degrees so 110+28=138 180-138=42 degrees. 42 degrees is the final interior angle and the missing and the missing exterior angle is congruent to the 42 degree angle. So the missing exterior angle is 42 degrees

TV Cabinet TV screens are measured on the diagonal. If we have a TV-cabinet that is 72 inches long and 64 inches high, how large a TV could we put in the space (leave 2-inches on all sides for the edging of the TV)? Round your answer to the nearest tenth.
Answers
Answer:
94inStep-by-step explanation:
We are expected to solve for the diagonal of a rectangular shape.
given that the length, l=72in
width, w=64in
we can apply the Pythagoras theorem to solve for the diagonal since it corresponds to the hypotenuse of the rectangle
note: we are to leave 2-inches on all sides for the edging of the TV
l=72-2= 70 in
w=64-2=62
diag=√l^2+w^2
diag=√70^2+62^2
diag=√4900+3844
diag=√8744
diag=93.50 in
to the nearest tenth, it is 94in
