Box A contained 40 paperclips. Box B contained 23 paperclips. After Sally took an equal number of paperclips from each box, Box A then contained twice as many paperclips as Box B. How many paperclips did Sally take from each box?

Answers

Answer:

Step-by-step explanation:

Number of clips in box A = 40

Number of clips in box B = 23

If Sally took out 6 clips from each box

Remaining clips in box A = 40 - 6 = 34 which is twice of 17

Remaining clips in box B = 23 - 6 = 17

Answer:

Sally took 6 paperclips from each box

Step-by-step explanation:

Paper clips in Box A = 40

Paper clips in Box B  = 23

Let the equal number paperclips removed from each box = x

Number of clips in box A after taking 'x' clips = 40 -x

Number of clips in box B after taking 'x' clips = 23 -x

40 - x = 2*(23 -x)

40 - x = 2*23 - 2*x

40 -x = 46 - 2x  {Add 2x to both sides}

40 - x + 2x = 46          {Combine like terms}

40 + x = 46         {Subtract 40 form both sides }

x = 46 - 40

x = 6

A Ferris wheel is 35 meters in diameter and boarded from a platform that is 3 meters above the ground. The six o'clock position of the Ferris wheel is level with the loading platform. The wheel completes one revolution in 8 minutes. The function, h(t), gives your height in meters above the ground t minutes after the wheel beings to turn. How high are you off the ground after 6 minutes

Answers

Answer:

height = 20.5068 m    

Step-by-step explanation:

Given the data in the question;

First, lets calculate the amplitude, midline and period of 8minutes

Amplitude = 35 / 2 = 17.5

|A| = 17.5

A = - 17.5  { since the wheel starts at 6 o clock }

midline  C = (35/2) + 3

C = 17.5 + 3

C = 20.5

And period is 8 minutes

⇒ 2π/B = 8

8B = 2π

B = 2π/8 = π/4

So our equation will be in the form of;

y = h(t) = Acos(B×t) + C

∴ h(t) = -17.5cos( π/4×t) + 20.5  

Now, How high are you off the ground after 6 minutes

⇒ height = -17.5cos( π/4 × 6) + 20.5

height = -17.5cos( π/4 × 6) + 20.5    

height = -17.5cos( 4.71238898) + 20.5    

height = -17.5 × cos( 4.712) + 20.5  

height = -17.5 × -0.00038898 + 20.5                  

height = 0.0068 + 20.5  

height = 20.5068 m    

Find in the missing values to make the equations true.

According to a recent study, the mean number of hours college students spent playing video games per month was 22 hours with a population standard deviation of 2 hours. Two weeks before final exams were scheduled to begin, 100 college students were randomly selected. What is the probability that the mean number of hours spent playing video games is less than 21.8 hours

Answers

Answer:

0.15866

Step-by-step explanation:

Given that:

Mean, m = 22

Standard deviation, s = 2

Sample size, n = 100

P(x < 21.8):

Obtain the Zscore ;

Z = (x - m) ÷s/sqrt(n)

Z = (21.8 - 22) ÷ 2/sqrt(100)

Z = - 0. 2 ÷ 0.2

Z = - 1

P(Z < - 1)

From Z probability calculator :

P(Z < - 1) = 0.15866

Hence, Probability of obtaining a score less than. 21.8 is 0.15866

The amplitude of the function is 15 if the data approximates a transformation of the parent sine function option (D) is correct.

What is sin function?

It is defined as the function which is sinusoidal in nature, and it has a domain of all real numbers and lies between the [a, a] where is a amplitude of the function.

We have hotel manager recorded the percentage of rooms that were occupied each day over a period of 25 days.

As we can see in the graph, it is sin graph and the maximum value it attends is 15(=70-55)

And the minimum value is attends is -15(=40-55)

The graph will be:

y = 15sinx

a = 15

Thus, the amplitude of the function is 15 if the data approximates a transformation of the parent sine function option (D) is correct.

write 9/6 as a mixed number

Answers

Numerator. This is the number above the fraction line. For 9/6, the numerator is 9.
Denominator. This is the number below the fraction line. For 9/6, the denominator is 6.
Improper fraction. This is a fraction where the numerator is greater than the denominator.
Mixed number. This is a way of expressing an improper fraction by simplifying it to whole units and a smaller overall fraction. It's an integer (whole number) and a proper fraction.

Now let's go through the steps needed to convert 9/6 to a mixed number.

Step 1: Find the whole number

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

9/6= 1.5 = 1

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (1) and multiply it by the original denominator (6). The result of that multiplication is then subtracted from the original numerator:

9 - (6 x 1) = 3

Step 3: Our mixed fraction

We've now simplified 9/6 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

1
3
6


9/6 can be written as the mixed number 1 1/2.

This means there is 1 whole unit and 1/2 (or half) remaining.

To write 9/6 as a mixed number, we need to divide the numerator (9) by the denominator (6).

When we divide 9 by 6, we get a quotient of 1 and a remainder of 3.

So, 9 divided by 6 is 1 with a remainder of 3.

We can express this as a mixed number by combining the whole number and the fraction:

1 + 3/6

However, the fraction 3/6 can be simplified. Both the numerator and denominator share a common factor of 3.

Dividing both by 3 gives us:

1 + 1/2

Now, we have the whole number part (1) and the proper fraction part (1/2).

Putting it all together, the mixed number representing 9/6 is: 1 1/2

Therefore, 9/6 can be written as the mixed number 1 1/2.

This means there is 1 whole unit and 1/2 (or half) remaining.

So, 9/6 as a mixed number is 1 1/2.

Hi! I’ve already gotten this far, and found the value of x, but how would I go about finding the value of y from here?

Answers

Answer:

y=1 and x = 2

Step-by-step explanation:

Given equations are :

2x-2y = 2 ....(1)

5x+2y= 12 .....(2)

Adding equation (1) and (2),

2x+5x = 2+12

7x = 14

x = 2

Put the value of x in equation (!).

2(2)-2y = 2

4-2y=2

2=2y

y=1

So, the values of x and y are 2 and 1 respectively.
