24 : 22 = x : 77

x = 24 * 77 : 22

x = 84

-------------------------

24 : 22 = 1,090909090909091

84 : 77 = 1,090909090909091

the answer is good

Answer:

The answer is x=84

Step-by-step explanation:

Step 1  X/77

Equation at the end of step 1  24/22 - x/77= 0

Step 2 Simplify 12/11

Equation at the end of step 2 12/11 - x/77 =0

Find lest common multiple left denomaintor is 11 and Right is 77

Now its 12*7-(x)/77= 84-x/77

84-x/77 *77= 0 * 77

subtract 84 from both sides -x=84 multiply both sides of the equation by (-1): x =84

So your answer is 84

A wastewater treatment plant receives 20million gallons per day (mgd) of flow. This wastewater has a solid concentration of 384m
xxMikexx [17]

Answer:

64,092.73 pounds

Step-by-step explanation:

1 gallon = 3.78541 liter

1 pound = 453592 mg

In order to obtain the weight of solids that enter the plant each day, simply multiply the wastewater flow by the solids concentration and make the necessary unit adjustments:

W=20,000,000\ gal*384\frac{mg}{L}*\frac{3.78541\ L}{1\ gal}*\frac{1\ lbs}{453592\ mg} \\W=64,092.73\ lbs

64,092.73 pounds of solids enter the plant each day.

Find the solution to the system of equations.
Tanya [424]

Answer:

x = - 4, y = 7

Step-by-step explanation:

Given the 2 equations

- 7x - 2y = 14 → (1)

6x + 6y = 18 → (2)

Multiplying (1) by 3 and adding to (2) will eliminate the y- term

- 21x - 6y = 42 → (3)

Add (2) and (3) term by term to eliminate y

- 15x = 60 ( divide both sides by 15 )

x = - 4

Substitute x = - 4 into either of the 2 equations and evaluate for y

Substituting into (2)

6(- 4) + 6y = 18

- 24 + 6y = 18 ( add 24 to both sides )

6y = 42 ( divide both sides by 6 )

y = 7

Find cos(2115°) and sin(2115°). Identify the measure of the reference angle.
ivolga24 [154]

Answer:

Cos(2115°) =1/√2

Sin(2115°) = -1/√2

Step-by-step explanation:

We have to find the values of Cos (2115°) and Sin (2115°).

Now, 2115° can be written as (23×90°+ 45°).

Therefore, the angle 2115° lies in the 4th quadrant where Cos values are positive and Sin values are negative.

Hence, Cos (2115°) = Cos(23×90° +45°) =Sin 45° {Since 23 is an odd number, so the CosФ sign will be changed to SinФ} =1/√2 (Answer)

Again, Sin (2115°) = Sin(23×90° +45°) = -Cos 45° {Since 23 is an odd number, so the SinФ sign will be changed to CosФ} = -1/√2 (Answer)

Now, the required reference angle is 45°. (Answer)
