Answer:
1/6
Step-by-step explanation:
total no. of fruits = 36

We can calculate the total price in dollars (d) based on the pounds of ribeye steak (s) sold using the equation d=8s. What would be the total price (d) of 4 pounds of steak?
Answer:
$32
Step-by-step explanation:
The variables in this equation are already defined. So we know that whatever d is equal to will be the cost, and therefore, the final answer. Additionally, s is the number of pounds of steak, so it is an independent variable. To solve this equation, plug in the number of pounds, 4, into the equation for s. Also, 8 is the unit price for the steak, so this multiplied by the amount of steak must be the total cost. This makes the new equation, d=8(4). Finally, multiply these numbers to get d=32. So the final cost for 4 pounds of steak must be $32.
Answer:
32 dollars
Step-by-step explanation:
The Equation to calculate the total price(d) based on the pounds of ribeye steak(s) sold if given as:
d = 8S
So, to calculate the total price(d) of 4 pounds of steak, all we need do is to substitute 4 into the given formula
That is,
d = 8(4)
d = 32 dollars
Therefore the price of 4 pounds of steaks is 32 dollars

A piano has a length of 8 feet and a width of x+2 feet, write an expression in simplest form of the perimeter of the piano.
Answer: 2(x + 10)
Step-by-step explanation: you have to add all of the perimeter sides together so you will have to times the length by 2 so your equation would be (8 × 2 = 16). Then the width by 2 ( 2 × (x+2) = 2x + 4) now you add them together
16 + 2x + 4
2x + 20
Now you have to take out the highest common factor which is 2
So it will be 2(x + 10)

in a sale, the normal price of a hat is reduced by 15%
The sale price of the hat is 20.40 euros.
Work out the normal price of the hat.
Answer:
The correct answer is 24
Step-by-step explanation:
To solve this math problem, you will need to divide 20.40 with 1 (1 is 100% as a decimal) and 0.15 (0.15 is 15% as a decimal).
--
[tex]20.40[/tex] ÷ [tex](1-0.15)[/tex]
--
First, subtract 1 and 0.15
[tex]1-0.15=0.85[/tex]
Next, divide 20.40 and 0.85
[tex]20.40[/tex] ÷ [tex]0.85 = 24[/tex]
--
Therefore, the final product of this math problem is 24
∠A and \angle B∠B are complementary angles. If m\angle A=(7x+23)^{\circ}∠A=(7x+23)
∘
and m\angle B=(5x+19)^{\circ}∠B=(5x+19)
∘
, then find the measure of \angle B∠B.
Since there are complementary angles, the value of angle B is 39°.
Angle A = 7x + 23°
Angle B = 5x + 19°
It should be noted that the total angles in a complementary angle are equal to 90°.
Therefore, we need to add angle A and B together and then equate them to 90°. This will be:
7x + 23° + 5x + 19° = 90°
Collect like terms
12x + 42° = 90°
12x = 90° - 42°
12x = 48°
x = 48°/12
x = 4°
Angle A = 7x + 23° = 7(4) + 23° = 28° + 23° = 51°
Angle B = 5x + 19° = 5(4) + 19° = 20° + 19° = 39°
The value of angle B is 39°.

A biologist is developing two new strains of bacteria. Each sample of Type 1 bacteria produces four new viable bacteria, and each sample of Type II bacteria produces three new viable bacteria. Altogether, at least 240 new viable bacteria must be produced. At least 20, but not more than 60, of the original samples must by Type I. Not more than 70 of the original samples can be Type II. A sample of Type I costs $5 and a sample of Type II costs $7. How many samples of each bacteria should the biologist use to minimize the cost? What is the minimum cost?
The cost can be optimized by using a Linear Programming given the linear constraint system
To minimize the cost, the biologist should use 60 samples of Type I bacteria and 0 samples of Type II bacteriaReason:
Let X represent Type 1 bacteria, and let Y, represent Type II bacteria, we have;
The constraints are;
4·X + 3·Y ≥ 240
20 ≤ X ≤ 60
Y ≤ 70
P = 5·X + 7·Y
Solving the inequality gives;
4·X + 3·Y ≥ 240

Find out the area of the marble slab.
Remember, the units are to be made same.
Now, to know the number of marble tiles required to fill the hall, you just have to divide the area of the hall with the area of the marble tile.
Calculations-
Area of the rectangular hall = length x width = 1600 x 1200 (we converted 'm' to 'cm') = 1920000 sq. cm.
Area of one marble tile = 25 x 15 = 375 sq. cm.

please help me solve x please
Answer:
x = 5
Step-by-step explanation:
The exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles.
In the given problem, the exterior angle is < B, and the non-adjacent interior angles are < D and < C.
Given that:
< B = 12x + 8
< D = 8x + 8
< C = 20°
Set up the following formula to solve for x:
(8x + 8) + 20 = 12x + 8
Combine like terms:
8x + 28 = 12x + 8
Subtract 8 from both sides:
8x + 28 - 8 = 12x + 8 - 8
8x + 20 = 12x
Subtract 8x from both sides:
8x - 8x + 20 = 12x - 8x
20 = 4x
Divide both sides by 4 to solve for x:
20/4 = 4x/4
5 = x
Therefore, x = 5.
A scale model of a bus is 12 inches long. The scale is 1:21. How many inches long is the bus it
represents?
its 304.8 milimeter
The actual length of the bus that the scale model represents is 252 inches.
To find the actual length of the bus represented by the scale model, you can use the scale ratio.
Given:
Scale model length = 12 inches
Scale ratio = 1:21
Let "x" be the actual length of the bus.
Using the scale ratio:
Scale model length / Actual length = Scale ratio
12 inches / x inches = 1/21
Now, solve for "x":
x = 12 inches / (1/21)
x = 12 inches × 21
x = 252 inches
Therefore, the actual length of the bus that the scale model represents is 252 inches.

Which quadratic equation contains the three points (-4,12), (2,42), and (3,40)
The quadratic equation that contains the three points is y = -x² + 3x + 40
A quadratic equation is in the form:
y = ax² + bx + c
At point (-4, 12):
12 = a(-4)² + b(-4) + c
16a - 4b + c = 12 (1)
At point (2, 42):
42 = a(2)² + b(2) + c
4a + 2b + c = 2 (2)
At point (3, 40):
40 = a(3)² + b(3) + c
9a + 3b + c = 40 (3)
Solving equation 1, 2, and 3 gives:
a = -1, b =3, c = 40
y = -x² + 3x + 40
