A man is 8x years old now. How old he will be in:
a. 10 years time? b. 6x years time?

Answer:

3 students are eating lunches other than salads and sandwiches.

Step-by-step explanation:

To solve this you know that there are 18 students in the cafeteria and 1/6 of them are eating salads and 2/3 are eating sandwiches right? So you would have to think about what 1/6 of 18 is so you know how many students are eating salads, and 1/6 of 18 is 3 so there are 3 students eating salads. Now, you have to find out how many students are eating sandwiches, so you need to know what 2/3 of 18 is. 2/3 of 18 is 12 so now you also know that there are 12 students eating sandwiches. Next, you have to add 12 and 3 and you get 15. Since you know that there are 18 students in the cafeteria, you have to subtract 18 by 15, and you should get 3. So 3 students are eating lunches other than salads or sandwiches.

Hope this helps you! :D

Answer:

The percentage discount given for the handbag is 90.48%.

Step-by-step explanation:

From the question, the following can be obtained:

D = Total discount on the two items = $1946.60

T = Total amount spent on the two items = $1940.40

r = Percentage discount given for the ring = 25%, or 0.25

h = Percentage discount given for the handbag = ?

H = Amount spent on the handbag = ?

Since Helene spent $458.40 less on the ring than on the handbag, therefore we have:

R = Amount spent on the ring = H - $458.40

From the above, we have:

T = H + R

T = H + H - $458.40

T = 2H - $458.40 …………………… (1)

Substituting T = $1940.40 into equation (1) and solve for H, we have:

$1940.40 = 2H - $458.40

$1940.40 + $458.40 = 2H

$2,398.80 = 2H

H = $2,398.80 / 2

H = $1,199.40

Since,

R = H - $458.40 ……………………. (2)

By substituting H = $1,199.40 into equation (2), we have:

R = $1,199.40 - $458.40

R = $741

Amount of discount on ring = r * R = 25% * $741 = $185.25

Amount of discount on handbag = D - Amount of discount on ring = $1946.60 - $185.25 = $1,761.35

h = Amount of discount on handbag / H = $1,761.35 / $1,199.40 = 0.90483406965992, or 90.483406965992%

Rounding to 2 decimal places, we have:

h = 90.48%

Therefore, the percentage discount given for the handbag is 90.48%.

Step-by-step explanation:

Answer: 72 miles.

Step-by-step explanation:

We know the relationship:

Distance = speed*time.

Then we can write the equation for distance as a function of time for Ali as:

A(t) = 12mph*t

where t is time in hours.

Fatimah's equation will be:

F(t) = 18mph*(t - 2h)

where the -2h appears because she starts two hours after Ali.

Fatimah will overtake Ali when F(t) = A(t) (their positions are the same)

Then we need to solve:

12mph*t = 18mph*(t - 2h)

12mph*t = 18mph*t - 18mph*2h

12mph*t = 18mph*t - 36 mi

36 mi = (18mph - 12mph)*t

36mi = 6mph*t

36mi/6mph = t

6h = t

So Ali travels for 6 hours before he gets overtaken, then the total distance that Ali travels is:

A(6h) = 12mph*6h = 72 mi

I added more places after the decimal in case you need to round it.

Answer:

-28 degrees Fahrenheit

Step-by-step explanation:

Since it changed -4 every hour for 7 hours, you would do -4 x 7 to get the answer, which equals -28. So your answer is -28 degrees Fahrenheit if I'm not mistaken.

Answer: 5 friends

Step-by-step explanation:

Khalid has $30 and each ticket is $4.

He needs to buy for both himself and his brother which would reduce the money to:

= 30 - 4 - 4

= $22

If each ticket is $4, the number of friends he can invite is:

= Amount of money he has / Price per ticket

= 22 / 4

= 5.5 friends

Step-by-step explanation:

The statement the line best fit has been an estimate and cannot be calculated. Therefore, the given statement is true.

The best fit line can be defined as the line created by connecting the majority of the points in a scatter plot. Depending on the scatter plot's points, the best fit line may take the form of a straight line or a curve.

The scatter plot's relationships between the variables are better understood when the best fit is used. The maximum scattered point serves as the line's best fit's pivot point.

The predicted line that best matches the plot depends on whether the straight-line equation fits it. As a result, it has not been able to measure the line of optimum fit.

Therefore, the given statement is true.

1. Reflection

2. B"

Step-by-step explanation:

Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just don’t want to waste my time in case you don’t want me to :)

The type of transformation which maps the triangle ABC to A'B'C' is given by reflection and the vertex of B' after reflection is B''

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Given data ,

Let the triangle be represented as ΔABC

Now , the transformed triangle is A'B'C'

where the triangle is reflected along the x axis

So , the reflected triangle is ΔA'B'C'

Now , the triangle ΔA'B'C' is reflected along the line x = -2

So , the reflected triangle is ΔA''B''C''

And , the vertex of B' after reflection is B''

Hence , the transformation is reflection of triangle ABC

Step-by-step explanation:

12x+24x+18 = 36x+24-6

Combine like terms

36x+18 = 36x+18

Subtract 36x from each side

36x+18-36x = 36x+18-36x

18 = 18

This is always true, so the equation is true for all values of x

Answer:

The original weight of the box was 14.36 ounces

Step-by-step explanation:

Percentages

The height of the macaroni boxes of a certain company decreased by 6%. Let's call x to the original weight of the box.

Calculating 6% of the price:

6/100*x = 0.06x

Subtracting from the original price:

x - 0.06x = 0.94x

This is the discounted price and it's known to be 13.5 ounces, thus:

0.94x=13.5

Dividing by 0.94:

x = 13.5/0.94

x = 14.36 oz

The original weight of the box was 14.36 ounces
