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

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.

David is considering changing his car to one which used liquefied
petroleum gas (LPG). A litre of LPG costs £0.62 and a litre of petrol
costs £1.29. What is the cost of a litre of LPG as a percentage of the
cost of a litre of petrol (give your answer to the nearest whole number)?
Answer:
48%
Step-by-step explanation:
A liter of LPG costs £0.62
A liter of petrol costs £1.29.
Therefore,
The cost of a liter of LPG as a percentage of the cost of a liter of petrol is calculated as:
Cost of LPG/ Cost of Petrol × 100
= £0.62/£1.29 × 100
= 48.062015504%
Approximately to the nearest whole number = 48%

Actually Welcome to the Concept of the Angle sum property of a Triangle.
hence,
==> 4x + 8° + 60° + 60° = 180
==> 4x + 128° = 180°
==> 4x = 180 - 128
==> 4x = 52°
==> x = 52/4
==> x = 13°
hence the value of x = 13 °

Marys family had to pay 3$ for the car plus 2$ for each number of people in the car.
x= how many people are there?
Answer:
y=2x+3
Step-by-step explanation:
Y is the total amount that the family pays. 2x represents 2 dollars for every person (so, 2 multiplied by the number of people). Finally, 3 represents the initial amount that they must pay, no matter how many are in the car.
Answer:
The expression that could be used is 2x+3
Step-by-step explanation:
This expression can be used because it costs $2 per person. Therefore, you would need to multiply 2 by however many people there are (x representing the number of people). Then, you would need to add an additional $3 because that is the cost for the car.

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

−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.

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

MODELING WITH MATHEMATICS The fire escape forms a right triangle, as shown. Use the Pythagorean Theorem to approximate the distance between the two platforms. Round your answer to the nearest tenth.
Answer:
[tex]x = 14.13ft[/tex]
Step-by-step explanation:
Given
See attachment for illustration
Required
Find x
To do this, we apply Pythagoras theorem.
From the attachment, the length of the hypotenuse is 16.7ft
While the length of the opposite/adjacent is 8.9ft
Length x is calculated using:
[tex]16.7^2 = 8.9^2 + x^2[/tex]
[tex]x^2 = 16.7^2 - 8.9^2[/tex]
[tex]x^2 = 199.68[/tex]
Take square roots
[tex]x = \sqrt{199.68[/tex]
[tex]x = 14.13ft[/tex]
The distance between the two platforms should be 14.13 ft.
Calculation of the distance;Since the length of the hypotenuse is 16.7ft.
And, length of the opposite/adjacent is 8.9ft.
Now the distance between should be
[tex]16.7^2 = 8.9^2 + x^2\\\\x^2 = 16.7^2 - 8.9^2\\\\x^2 = 199.68\\\\x = \sqrt{199.68}[/tex]
= 14.13 ft.
hence, The distance between the two platforms should be 14.13 ft.
