A group of friends were working on a student film. They spent all their budget on props and equipment. They spent $912 on props, and 24% of the total budget on equipment. What was the total budget for their student film?
Answer:
Total Budget: $1200
Step-by-step explanation:
76% = 912
1% = 12
100% = 12 x 100 = $1200
I brute forced till I got the number which multiplied by 76 came out to 912 from there I had what was 1% of the budget then I multiplied that by 100 for the answer.
The total budget for their student film is $1200.
What is the percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
A group of friends were working on a student film.
They spent all their budget on props and equipment.
They spent $912 on props, and 24% of the total budget on equipment.
Let us represent the total budget of the film as: x
The amount spent on equipment = $870
The amount spent on props = 24% of x
Total budget = Amount spent on equipment + Amount spent on props
x = 912 + 24% of x
x = 912 + 0.24x
x - 0.24x = 912
0.76x = 912
x= 912/0.76
x = $1200
Hence, the total budget for their student film is $1200.

A restaurant chef was ordering supplies. He ordered 9 pounds of beef at 7.53 per pound, 9 pounds of potatoes at $6.45 a pound and 4 pounds of carrots at $6.23 per pound. He estimates that this will make 27 meals. If he charges 39.53 per meal how much profit will he make
Answer:
916.57 pounds
Step-by-step explanation:
Cost of beef = 7.53 pounds × 9
= 67.77 pounds
Cost of potatoes = 6.45 pounds × 9
= 58.05 pounds
Cost of carrots = 6.23 pounds × 4
= 24.92 pounds
Total cost = 67.77 pounds + 58.05 pounds + 24.92 pounds
= 150.74 pounds
Total revenue = 27 meals × 39.53 pounds
= 1067.31 pounds
Total profits = Total revenue - Total cost
= 1067.31 pounds - 150.74 pounds
= 916.57 pounds

F a student drives 30 miles north, the 40 miles east, then 60 more miles north and finally 80 more miles east, exactly how far is she from her starting point? (As the crow flies.)
Answer:
150 miles
Step-by-step explanation:
The movements are represented as:
[tex]N1 = 30miles[/tex]
[tex]E1 = 40miles[/tex]
[tex]N2 = 60miles[/tex]
[tex]E2 = 80miles[/tex]
Required
Determine the distance from the starting point
The student's movement is illustrated with the attached image.
First, calculate the total distance towards North.
[tex]N = N1 + N2[/tex]
[tex]N = 30 + 60[/tex]
[tex]N = 90[/tex]
Next, calculate the total distance towards East
[tex]E = E1 + E2[/tex]
[tex]E = 40 + 80[/tex]
[tex]E = 120[/tex]
The total distance from the starting point is calculated using Pythagoras theorem.
[tex]D^2 = N^2 + E^2[/tex]
[tex]D^2 = 90^2 + 120^2[/tex]
[tex]D^2 = 22500[/tex]
[tex]D = \sqrt{22500[/tex]
[tex]D = 150[/tex]

lines s and t intersect so that the measure of angle 1 is 85 degrees. if angle 2 is supplement to angle 1 what is the measure of angle 2
Answer:
95 degrees
Step-by-step explanation:
The sum of two supplementary angles is 180 degrees
Given
angle 1 = 85 degrees
If angle 2 is the supplement of angle 1, then
<1 + <2 = 180
85 + <2 = 180
<2 = 180 - 85
<2 = 95degrees
Hence the measure of angle 2 is 95 degrees

−2x=x2−6 Rewrite the equation by completing the square.
Answer:
(x + 1)² = 7
Step-by-step explanation:
Given:
-2x = x² - 6
We'll start by rearranging it to solve for zero:
x² + 2x - 6 = 0
The first term is already a perfect square so that's fine. Normally, if that term had a non-square coefficient, you would need to multiply all terms a value that would change that constant to a perfect square.
Because it's already square (1), we can simply move to the next step, separating the -6 into a value that can be doubled to give us the 2, the coefficient of the second term. That value will of course be 1, giving us:
x² + 2x + 1 - 1 - 6 = 0
Now can group our perfect square on the left and our constants on the right:
x² + 2x + 1 - 7= 0
x² + 2x + 1 = 7
(x + 1)² = 7
To check our answer, we can solve for x:
x + 1 = ± √7
x = -1 ± √7
x ≈ 1.65, -3.65
Let's try one of those in the original equation:
-2x = x² - 6
-2(1.65) = 1.65² - 6
- 3.3 = 2.72 - 6
-3.3 = -3.28
Good. Given our rounding that difference of 2/100 is acceptable, so the answer is correct.

36/2^5 over 8+7x(3+11)
Answer:
119.25
Step-by-step explanation:
36/32 simplified is 9/8.
8 + 7(3+11), I'm assuming it's not x.
8 + 7(14) = 106
(9/8)/106 = 9/8*106 = 954/8 = 119.25

Answer:
x = 5
Step-by-step explanation:
To get the value of x we will use similar triangles as shown;
AT/AG = AB/AC
9/3 = x+10/3x-10
Cross multiply
3(x+10) = 9(3x-10)
3x + 30 = 27x - 90
Collect like terms
3x - 27x = -90 - 30
-24x = -120
x = 120/24
x = 5
Hence the value of x is 5
