What is x?? I'm so confused!

Mathematics
1 answer:
LiRa [457]3 years ago
3 0

Answer:

x = 468%

Step-by-step explanation:

I see a proportion here.

we want to solve for the variable x in the proportion:

18% / (2 weeks) =   ( x %) / (52 weeks)

here we should multiply 52 to boths sides

(52 weeks) * 18%  / (2 weeks) =   x %

26  * 18% =  x %

x = 468 %

Danielle’s chemistry professor has a complicated grading system. Each lab counts once and each test counts as two labs. At the e
Murrr4er [49]

Answer:

92

Step-by-step explanation:

Lab Scores are 84, 81, and 93

Test Scores are 89 and 94

Each lab counts once and each test counts as two labs. At the end of the semester there is a final lab that counts as three regular labs.

Total Number of Labs= (3X1)+(2X2)+(1X3) =3+4+3 =10

To recieve an A(90), the average of her scores must be 90.

Let her final lab score =b

Refer to the attached diagram

Total Score=624+3b

For her average =90

\frac{624+3b}{10}=90

Cross multiplying

624+3b =90 X 10

624+3b =900

3b =900-624

3b =276

Dividing both sides by 3

b= 92

She must score 92 in her final lab to receive an A.

What is the mean of this data set? {6, 11, 5, 2, 7} Enter your answer as a decimal in the box.
Elenna [48]

Answer:

The mean is 6.2.

Step-by-step explanation:

The "mean" is the same thing as the "average". Essentially, the question is asking for the average of the numbers.

So:

Add up all of the terms. [6 + 11 + 5 + 2 + 7] = 31

You find the average by dividing the sum of the terms (31) by the number of terms (5).

31/5 = 6.2

The mean is 6.2.

I hope this helped! :)

Gary drove to the park at a rate of 50 miles per hour if it took him 2.5 hours to get from his house to the park how far away is
Marina86 [1]

Answer:

The distance of the park from the Gary's house is 125 miles.

Step-by-step explanation:

Speed of Gary = 50 miles/hour

Time taken by Gary to reach the park from his house = 2.5 hours

Now, we know that,

Distance travelled = speed × time

So,  distance between park and Gary's house = speed × time

= 50 × 2.5

= 125 miles

So, the park is 125 miles away from the Gary's house.
