Step-by-step explanation:
2/7 = n/21
How I do it is:
1. I put it like this: n7=2 times 21
then I multiply 2 times 21 which is 42
2. then it becomes n7=42 which basically is 42/7 which is 6 so N=6

The boiling point of jet fuel is 329°F.
Rounded to the nearest degree, what is
the temperature in degrees Celsius?
Use the formula C = (F – 32), where
C represents degrees Celsius and F
represents degrees Fahrenheit.
Answers
Answer:
Boiling point of jet fuel = 165 degrees Celsius
Step-by-step explanation:
Given:
Boiling point of jet fuel = 329°F
Find:
Boiling point of jet fuel in degrees Celsius
Computation:
C = [5/9][F – 32]
C = [5/9][329 – 32]
C = 165
Boiling point of jet fuel = 165 degrees Celsius

B: y − 3 = 2/3(x − 4)
C: y − 3 =− 2/3(x − 4)
D: y − 3 = −3/2(x − 4)
Answers
Answer:
B. [tex] y - 3 = \frac{2}{3}(x - 4) [/tex]
Step-by-step explanation:
We can create an equation to represent the graph in point-slope form, given as [tex] y - y_1 = m(x - x_1) [/tex], by using a point (x1, y1) on the line, (4, 3) and the slope (m) of the line.
Let's find slope using the two points (4, 3) and (-2, -1).
[tex] slope (m) = \frac{y_2 - y_1}{x_2 -x_1} = \frac{-1 - 3}{-2 - 4} = \frac{-4}{-6} = \frac{2}{3} [/tex]
Substitute m = ⅔, x1 = 4, and y1 = 3 in [tex] y - y_1 = m(x - x_1) [/tex].
The equation that represents the graph would be:
✅[tex] y - 3 = \frac{2}{3}(x - 4) [/tex],

A football team has a squad of 24 players,
1/12 of their squad are suspended, some of the squad are injured, and this leaves only 14 players to choose a team from,
What fraction of the squad are injured?
Answers
Answer:
1/3.
Step-by-step explanation
1/12 * 24 = 2 players suspended leaving 22 players.
So the number injured = 22 - 14 = 8.
Fraction injured = 8/24 = 1/3.

Answers
Answer:
Solving the inequality [tex]28-K\geq 7(K-4)[/tex], we get [tex]\mathbf{K\leq 7}[/tex]
Step-by-step explanation:
We need to solve the inequality [tex]28-K\geq 7(K-4)[/tex]
Using the BODMAS rule, first we will solve the bracket:
[tex]28-K\geq 7(K-4)\\28-K\geq 7K-28[/tex]
Now, we will subtract 28 from both sides
[tex]28-K-28\geq 7K-28-28\\-K\geq 7K-56[/tex]
Subtracting -7k on both sides
[tex]-K-7K\geq 7K-56-7K\\-8k\geq -56[/tex]
Finally, divide both sides by -8 and inverse the inequality, as we are dividing with a minus digit.
[tex]\frac{-8K}{-8}\leq \frac{-56}{-8}\\K\leq 7[/tex]
So, solving the inequality [tex]28-K\geq 7(K-4)[/tex] we get [tex]\mathbf{K\leq 7}[/tex]

Enter a linear equation that describes the problem.
An equation for the amount of money made by the gym is = $1188, where m is the number of
monthly memberships sold, and w is the number of reusable water bottles sold.
Answers
Answer:
x = gym memberships, and y = bottles of water
30x + 7y = 1050.....when x = 28

7y = 210
y = 210/7

O 25 oz.
O 90 oz.
Answers
Answer:
90 OZ.
Step-by-step explanation:
You have to divide the ounces by the price to see how much $1 per ounce costs.
25 divided by 3.75 = 6.6 Ounces for $1
90 divided by 6.30 = 14.28 ounces for $1
Consider this right triangle. R 9 55° Q P Enter the length of RQ, to the nearest tenth.
Answers
Answer:
RQ = 7.4
Step-by-step explanation:
From the right triangle PQR,
m∠Q = 90°
m∠P = 55°
Hypotenuse PR = 9
By applying sine rule in the given triangle,
Sin(55°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
0.819152 = [tex]\frac{\text{RQ}}{\text{PR}}[/tex]
0.819152 = [tex]\frac{RQ}{9}[/tex]
RQ = 9×0.819152
RQ = 7.37

Explain in detail how would you plot the points –1, 5, –2.5, –3, and 2 on the number line. What is the order of the numbers?
Answers
Explanation:
The number line goes from the smallest number to the largest number. As an example you may ask why -3 is smaller than -1 even though it looks larger. This is because it actually isn’t since it is negative. When a number is negative, the higher the number are the smaller it is. One more example could be that -10 is smaller than -5.
Kristin wants to make 12 ml of an 8% alcohol solution by mixing together a 32% alcohol solution and pure water. How much of each solution must she use? Please put how many ml for the solutions.
Answers
Answer:
To obtain a solution of 12 ml of 8% alcohol, 3 ml of 32% alcohol and 9 ml of water should be used.
Step-by-step explanation:
To determine the amount of 32% alcohol and pure water needed to make a 12 ml 8% alcohol solution, the following calculation is necessary:
If in 12 ml it is sought that 8% of the solution is alcohol, this percentage implies a presence of 0.96 ml of alcohol in the solution.
Now, 12 ml of 32% alcohol has 3.84 ml of alcohol in it, which must be lowered with water to access that amount.
Therefore, since 32/8 is equal to 4, a quarter of the solution composed of 32% alcohol must be placed, while the remaining three-quarters must be pure water.
In conclusion, to obtain a solution of 12 ml of 8% alcohol, 3 ml of 32% alcohol and 9 ml of water should be used.
