Answer:

r=63

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    r/3-(21)=0             r

Simplify   —

           3

r    

 — -  21  = 0

 3     2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  3  as the denominator :

         21     21 • 3

   21 =  ——  =  ——————

         1        3  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Answer:

6√24 or 29.39metres

Step-by-step explanation:

Area of a triangle is bh/2

The perimeter of an equilateral triangle is 3b

This equilateral triangle can be imagined as two adjoining 30-60-90 triangles. Together, their area is the given 24√3 m²

The base of the individual triangle is √24. The height is √24√3. Multiplying those factors, we get the given area, a proof of sorts, but mure importantly, we can calculate the length of the hypotenuse as 2√24.

sin(30°) = 0.5

√24/(0.5) = 2√24

That is the length of the side of the original equilateral triangle.

The perimeter is 3 times the length of the side:

(3)(2√24) = P

6√24 meters is the perimeter.

Answer: 2

Step-by-step explanation: By adding all the desserts together, you get 20, so you then divide that by the number of tables which is 10, therefore getting 2 which is the average/mean

Answer:

3(4 + 3 + 17)

Step-by-step explanation:

The greatest common factor of the three numbers is 3. The equation would then become 3(4 + 3 + 17)

Answer:

y is 11

Step-by-step explanation:

-7y = -77

Divide both sides by -7

-7y/-7 = -77/-7

Since it's -77/-7, a negative divided by a negative gives us a positive output.

Y=11 is our final answer.

Answer:

3(12x - 24) = 16 (use the distributive property)

36x - 72 = 16  (add 72 to both sides to get the x-term alone)

36x = 88 (divide both sides by 36 to isolate x)

x = 2.4 (the four is repeating. that's the exact answer.)

I would say the answer is A because 2.4 is close to 2 than any of the other answers.

Answer:

6.9−8=2

Step-by-step explanation:

(8−5)2.3−8=2

Subtract 5 from 8 to get 3.

3×2.3−8=2

Multiply 3 and 2.3 to get 6.9.

6.9−8=2

Subtract 8 from 6.9 to get −1.1.

−1.1=2

Compare −1.1 and 2.

The inequality to ensure the mixing machine functions properly is,

D. 150x + 800 < 2800

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

From the given information and the statement that the combined weight should not exceed  2800 pounds the inequality that represents the number of loads it can take  to ensure the mixing machine functions properly is,

150x + 800 < 2800.

Answer:

1/6 of the tomatoes

Step-by-step explanation:

So first, after she uses 5/9 she has 1 - 5/9 = 4/9 of her tomatoes left. Then, she uses 5/8 of that 4/9 to make a salad, so she used 5/8 * 4/9 = 5/18 of her tomatoes overall.  That means that she has 4/9 - 5/18 = 8/18 - 5/18 = 3/18 = 1/6 of her tomatoes saved.

Step-by-step explanation:

Answer:

(f + g)(x) = 2x² + x - 5

Step-by-step explanation:

Given

[tex]f(x) = -2[/tex]

[tex]g\left(x\right)\:=\:2x^2+\:x-3[/tex]

To determine

(f + 9)(x) = ?

Using the formula

(f + g)(x) = f(x) + g(x)

substituting f(x) = -2 and g(x) = 2x² + x - 3

             = -2 + 2x² + x - 3

             = 2x² + x - 5

Therefore, we conclude that:

(f + g)(x) = 2x² + x - 5

Both Question (bottom right corner)

Step-by-step explanation:

Question 2 is obviously a variable because the amount of goals you can score in a game varies, one game it could be 10 then next it could be 5, But for question 1 the amount of work hours she puts in, (assuming she choses when to work and when not to) is also a variable because the amount she works varies from day to day.

Both these examples how data that varies from day to day.
