2.) 50 x 6 = 300
3.) 2,124 / 36 = 59
4.) 180 / 36 = 5 | 240 / 5 = 48
5.) 6 / 2 = 3 | 4 x 3 = 12
Hope this helps.
If there is something wrong, please let me know.
Proportional reasoning refers to the ability to compare and analyze relationships between two or more quantities that change in a consistent way. It involves understanding the concept of proportionality and applying it to solve problems.
1.) If a business jet burns 300 gallons of gasoline per hour, it burns 900 gallons of gasoline in a three-hour flight. This can be calculated by multiplying the burn rate of 300 gallons per hour by the duration of the flight, which is three hours.
2.) On average, one gallon of gasoline weighs approximately six pounds. Therefore, fifty gallons of gasoline weighs 300 pounds. This can be calculated by multiplying the weight of one gallon (six pounds) by the quantity of fifty gallons.
3.) For every one yard, there are thirty-six inches. To find the number of yards in 2,124 inches, we divide 2,124 by 36. The result is 59 yards. This can be calculated by dividing the total number of inches by the conversion factor of thirty-six inches per yard.
4.) A person who weighs 240 pounds burns 180 calories per mile of running. A person who weighs 48 pounds, burns thirty-six calories while running one mile. To find the number of pounds for which the person burns thirty-six calories while running one mile, we can set up a proportion. If we let x represent the weight in pounds, the proportion would be: 240 pounds / 180 calories = x pounds / 36 calories. Solving for x gives us x = 48 pounds.
5.) A rice casserole recipe serves four people and requires two tablespoons of butter. If a rice casserole requires six tablespoons of butter, it serves twelve people. This can be determined by setting up a proportion: 4 people / 2 tablespoons = 12 people / 6 tablespoons. Solving for the unknown number of people gives us 12 people.

Suppose a river flows south to north at a velocity of 1 m/s, and a motorboat traverses the river from east to west at a speed of 2.5 m/s. At what angle should the boat be oriented south, relative to the westward direction, such that the boat will be traveling due west? Round to the nearest degree.
Answer: [tex]24^{\circ}[/tex]
Step-by-step explanation:
Given
River is flowing from south to North with a velocity of [tex]u=1\ m/s[/tex]
Motor boat traverses the river from east to west at a speed of [tex]v=2.5\ m/s[/tex]
South component of boat velocity must compensate the river velocity in order to travel in west direction.

Write if the statement presented is "True" or "False." If False, Justify. "The simplified ratio of 27:36 is 4: 3"
Answer:
FALSE. isn't it supposed to be 3 : 4.
Step-by-step explanation:
Simplified would be 27÷ 9 =3 and 36 ÷ 9 =4
============================================================
Explanation:
The ratio 4:3 has the first part (4) larger than the second part (3)
The ratio 27:36 has it flipped around, where the second part is the larger item this time.
Based on this alone, we can see that there's no way that 4:3 is the same as 27:36
--------------
Another way you can look at it is to divide both parts of 27:36 by the GCF 9
27/9 = 336/9 = 4The ratio 27:36 fully reduces to 3:4 and not 4:3. The order matters.
--------------
Or you could go in verse of the previous section. Multiply both parts of 4:3 by 9
9*4 = 369*3 = 27So the ratio 4:3 is equivalent to 36:27 which is not the same as 27:36. Again, the order is important.
--------------
Yet another approach:
Treat the ratios like fractions. If they were equal, then 27/36 = 4/3 would be true.
Cross multiplying leads to 27*3 = 36*4 and that becomes 81 = 144 which is false. So saying 27:36 reduces to 4:3 is also false

find the value of x.
show working please.
You can solve this problem by inspection or by plotting.
x^2 = 16^x
x^2 = 2^(4x)
x = 2^(2x)
Take log of both sides:
logx = 2xlog2
(logx)/x = 2log2
x^(1/x) = 2^2
x^(1/x) = 4
Plot problem:
x = -.5
Test (-.5)^(1/-.5) = 4, 4 =4
(-.5)^2 = 16^(-.5)
1/4 = 1/4
Answer is: -.5
According to the synthetic division below, which of the following statements are true? Check all that apply
The true statements are A , B , E
What is division?It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.
Here, In the synthetic calculation we use the coefficient of the dividend
with the factors of the function
∴ 2 , -2 , -12 are the coefficient of the dividend 2x² - 2x - 12
∵ The divisor is 3
∴ x = 3 is a root of F(x) = 2x² - 2x - 12
∵ x = 3 is the root of F(x) = 2x² - 2x - 12
- Subtract the two sides by 3
∴ x - 3 = 0
∴ (x - 3) is a factor of the dividend F(x) = 2x² - 2x - 12
- The quotient is the last line of the synthetic division
∴ The coefficients of quotient are 2 , 4
- The quotient is 1 degree less than the dividend
∵ The degree of the dividend is 2
∴ The degree of the quotient is 1
∴ The quotient is 2x + 4
* Lets check the answers to chose the write statements
A. The number 3 is a root of F(x) = 2x² - 2x - 12 ⇒ true
B. (x - 3) is a factor of 2x² - 2x - 12 ⇒ true
E. (2x² - 2x - 12) ÷ (x - 3) = 2x + 4 ⇒ true
Thus, the true statements are A , B , E.

triangles help pls!!
Answer:
x = 60
Step-by-step explanation:
The single dashed line represents congruent side lengths.
If every side of a triangle has a single dashed line then all of the sides are congruent meaning that the triangle is an equilateral
Equilateral triangles have all congruent side lengths and angles
In an equilateral triangle each angle has a measure of 60 degrees
So x = 60
Answer:
Step-by-step explanation:
A parallelogram is divided into two triangles, both triangles having equal sides.
So triangles are equilateral..In equilateral triangles, the angles are also equal..the interior angles of a triangle are 180 degrees..

6(x – 1) = 9(x + 2)
how do i get this right
Answer:
x = -8
Step-by-step explanation:
6(x – 1) = 9(x + 2)
Add 6 to both sides
6x - 6 + 6 = 9x + 18 + 6
Simplify
6x = 9x + 24
Subtract 9x from both sides
6x - 9x = 9x + 24 - 9x
Simplify
-3x = 24
Divide both sides by: -3
-3x/-3 = 24/-3
Simplify

James and his family spend a morning picking peaches. They fill several bags. This line plot shows the weight of each bag. How many more pounds does one of the heaviest bags weigh than one of the lightest bags? Enter your answer as a fraction in simplest form by filling in the boxes.
Answer:
The answer is "[tex]1\frac{1}{2}[/tex]"
Step-by-step explanation:
Please find the graph file of the question in the attachment.
Its first step is the lightest and heaviest evil. [tex]4 \frac{1}{4}[/tex] is the lightest bag, and [tex]5 \frac34[/tex] is the heaviest bag. To remove it now, it is not permissible to remove it as a mixed fraction, therefore convert each fraction into an improper fraction by multiplying the whole integer to the numerator, then adding a numerator to this amount, multiplied by the numerator. Follow those steps to find out [tex]4 \frac{1}{4}[/tex] is the wrong part.
[tex](4\times 4+1=17) \ so\ 4\frac14=\frac{17}{4}.[/tex] The process is the same for [tex]5 \frac34 (5\times 4+3=23) \ so \ 5 \frac34= \frac{23}{4}.[/tex]
You now deduce the numerator but just not the negative, to deduct both. You subtract, as the question is raised far as[tex]\frac{23}{4}-\frac{17}{4} =\frac{6}{4}[/tex] is involved. The last stage is that this is transformed into blended families, dividing its count by the denominator, 6 divided by 4 is identical to 1.5. 1 is a full amount so you don't modify it, but you do need to change the 5 decimals to [tex]1.5=1 \frac{5}{10}[/tex] and the last step is [tex]1\frac{1}{2}[/tex]to reduce.
