Answer:
77.5
Step-by-step explanation:
For 0.30 for the first 50, just subtract 50 from 175, that leaves 125.
(An easy way to do this is think of quarters, 25+25=50 and 50+25=75 so all you have to do is subtract two 25s and you know it's 125)
Put the 125 to the side, and multiply 50 to 0.30, you get 15.
Then for 0.50 over 50 containers, multiply the remaining 125 with 0.50, you get 62.5.
Add 62.5 and 15 together, that gives you 77.5

A triangle has an area of 66 in2. If the base is 11 inches, what is the height?
[tex] \Large{\boxed{\sf Height = 12 \ in}} [/tex]
[tex] \\ [/tex]
Explanation:The area of a triangle is given by the following formula:
[tex] \\ [/tex]
[tex] \left[ \begin{array}{c c c} \underline{\tt Area \ of \ a \ triangle \text{:}} \\ ~ \\ \tt A = \dfrac{B \cdot H}{2} \end{array} \right] [/tex]
Where:
A is the area of the triangle.B is the base.H is the height.[tex] \\ [/tex]
[tex] \Large{\boxed{\sf Given \text{:} } \ \begin{cases} \sf A &=\sf 66 \ in^2 \\ \sf B &=\sf 11 \ in \end{cases} } [/tex]
[tex] \\ [/tex]
Substitute these values into the formula and solve for H.
[tex] \sf A = \dfrac{B \cdot H}{2} \\ \\ \\ \longrightarrow \sf 66 \ in^2 = \dfrac{11 \ in \cdot H}{2} [/tex]
[tex] \\ [/tex]
Multiply both sides by 2:
[tex] \longrightarrow \sf 66 \ in^2 \cdot 2 = \dfrac{11 \ in \cdot H}{2} \cdot 2 \\ \\ \\ \longrightarrow \sf 132 \ in^2 = 11 \ in \cdot H [/tex]
[tex] \\ [/tex]
Divide both sides by 11in :
[tex] \longrightarrow \sf \dfrac{132 \ in^2 }{11 \ in } = H \\ \\ \\ \longrightarrow \boxed{\boxed{\sf H = 12 \ in}} [/tex]
[tex] \\ [/tex]

A triangle has an area of 66 in². If the base is 11 inches, what is the height?
Answer:The height of the triangle is 12 inches.
Step-by-step explanation:As per the provided information in the given problem, we know that the area of a triangle is given by 66 inches². The base of the triangle is given by 11 inches. In this problem, we are tasked to find the height of the triangle.
To do this, we will use the formula below:
[tex]\Large\begin{aligned}\rm\qquad\dashrightarrow{Area_{(Triangle)} = \dfrac{1}{2}bh}\end{aligned}[/tex]
Where:
The base is denoted as b.The height is denoted as h.Substitute the given values into the formula given earlier and solve for h:
[tex]\Large\begin{aligned}\rm\dashrightarrow{Area_{(Triangle)}}& = \rm{\dfrac{1}{2}bh}\\\rm\dashrightarrow{66\: in^2}& = \rm{0.5(11\: in)(h)} \\\rm\dashrightarrow{66\: in^2}& = \rm{(5.5\: in)(h)} \\\rm\dashrightarrow{\dfrac{66\: in^{\cancel{2}}}{5.5\: \cancel{in}}}& = \rm{\dfrac{(\cancel{5.5\: in})(h)}{\cancel{5.5\: in}}} \\\rm\dashrightarrow{12\: in}& = \rm{h}\end{aligned}[/tex]
Hence, the height of the triangle is 12 inches.

If the perimeter in the rectangle.is 18 inches, find the length of the sideshow
Answer:
5 inches and 4 inches
Step-by-step explanation:
The perimeter is equal to 2(2x + 1) + 2(x + 2) since there are two sides of the rectangle equal to the expressions given.
Since we also know that the perimeter is 18 inches, we can set that equal to 18.
2(2x + 1) + 2(x + 2) = 18
4x + 2 + 2x + 4 = 18
6x + 6 = 18
6x = 12
x = 2
After plugging 2 back into 2x + 1 and x + 2, you get 5 and 4. Hope this helped!
A net has a square at the center and 4 triangles on the sides. The square has side lengths of 2 yards. The triangles have a base of 2 yards and height of 3 yards.
What is the surface area of the square pyramid?
The surface area is
yd2.
Answer:
16 yd²
Step-by-step explanation:
The total surface area is the sum of the area of the square base and the 4 triangular sides.
SA = s² + 4 × bh/2
SA = (2 yd)² + 4 × (2 yd)(3 yd)/2
SA = 4 yd² + 12 yd²
SA = 16 yd²

You have 12 coins. Some quarters and dimes. You have a total of $2.40, how many of each coin do you have?
Answer:
8 quarters and 4 dimes
Step-by-step explanation:
4 quarters = 1 dollars
4 quarters = 1 dollars
4 dimes = 40 cents
2.40$
============================================
Work Shown:
d = number of dimes
q = number of quarters
1 dime = 10 cents
d dimes = 10d cents
1 quarter = 25 cents
q quarters = 25q cents
d+q = 12 since we have 12 coins total
q = -d+12 after solving for q
10d+25q = total value in cents
10d+25q = 240
10d+25(-d+12) = 240 ... plug in q = -d+12
10d-25d+300 = 240
-15d+300 = 240
-15d = 240-300
-15d = -60
d = -60/(-15)
d = 4
q = -d+12
q = -4+12
q = 8
Since d = 4 and q = 8, this means we have 4 dimes and 8 quarters
-----------------------------
Check:
4 dimes = 4*10 = 40 cents
8 quarters = 8*25 = 200 cents
(4 dimes) + (8 quarters) = (40 cents) + (200 cents) = 240 cents
240 cents = 240/100 = $2.40
We have 4+8 = 12 coins total

Select Not independent or Independent for each situation.

- A coin is flipped three times.
- A bag contains nickels and dimes. A nickel is selected followed by a dime, at random, with replacement.
- A number cube is rolled twice.
"Not independent" means that the situation is dependent. It is not relying on something else, or something else will not change the outcome. Independent means the situation is isolated, it is independent.
A jar contains green marbles and orange marbles. A green marble is selected followed by an orange marble, at random, without replacement.

Joy decided to ride her bike to visit her friend, Three miles from home her bike got a flat tire and she had to walk the remaining two miles to Justin's home. She could not repair the tire and had to walk all the way home. How many miles did Joy walk than she rode? They got the answer 4 but I am not sure how?
Answer:
4
Step-by-step explanation:
okay, so she rode 3 miles. Keep that aside
Then she had 2 walk the remaining 2 miles
She had to walk all the way home. So say for example instead of riding she walked 3 miles, then she walked that additional 2 miles. So, 5 miles. Then add the two miles she had to walk to his house. so, she walked 7 miles and rode 3 miles. 7-3= 4 miles. I attached a picture that should hopefully explain it better.

Regina currently makes $15 an hour. Her boss decided to give her a 7% raise. Write the expression she would use to determine how much more she will make per hour.
Answer:
[tex]\frac{7\times15}{100}[/tex]
Step-by-step explanation:
Given the following question:
7% of 15
To find the answer we need to use the formula to calculate percentages in which we multiply the percentage by the whole number and then divide that answer by 100, of course rounding to the nearest cent if needed.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{7\times15}{100}[/tex]
[tex]7\times15=105[/tex]
[tex]105\div=1.05[/tex]
[tex]=1.05[/tex]
7% of 15 is "1.05" which means Regina receives a $1.05 raise.

Solve for r in terms of q, s, and t
T=r-q+s
R=
Answer:
r = t + q - s
Step-by-step explanation:
t = r - q + s
goal is to isolate the variable
add q to both sides (this cancels the q out on the right side)
t + q = r - q + q + s
t + q = r + s
subtract s from both sides
t + q - s = r + s - s
t + q - s = r
In other words:
r = t + q - s

A rectangular prism has a length of 412 centimeters, a width of 412 centimeters, and a height of 6 centimeters. Sally has a storage container for the prism that has a volume of 143 cubic centimeters.
What is the difference between the volume of the prism and the volume of the storage container?
Enter your answer in the box as a simplified mixed number or a decimal.
cm³
Answer: First find the volume of the rectangle prism. Do this by multiplying all three dimensions. 412 x 412 x 6 = 1,018,464.
Subtract 1,018,464 from 143.
You should get 1,018,321 mm^3
(Remember that the units are cubed because you multipled 412 mm x 412 mm x 6 mm which is multiplying not only the numbers, but the mm three times as well.)
