Katie Fulton, a food supplements Representative, had sales of 5859 with allowances of $422. If her commission rate is 5%, find her gross earnings.

Answers

Apparently, Katie's net sales were $5859 -422 = $5437. Her commission on those sales was 0.05*$5437 = $271.85.

Katie earned $271.85.
Final answer:

Katie Fulton's gross earnings would be $271.85 as calculated deducting allowances from total sales and then applying the 5% commission rate.

Explanation:

In this problem, Katie Fulton, the food supplements Representative, had total sales of 5859 dollars and the allowance has to be deducted from the total sales making the correct value for calculation 5437 dollars ($5859 - $422 = $5437).

Given that she earns a commission of 5%, we can calculate her gross earnings by multiplying her sales after allowance with this commission rate:

Gross Earnings = Commission rate * Sales after allowance = 0.05 * 5437 = $271.85.

So, Katie Fulton's gross earnings would be $271.85.

Answers

The answer is 854 for sure. I did the test and got it all right.

Answer:

854 customers.

Step-by-step explanation:

An online store randomly samples three groups of 100 customers on which delivery method they use. The data shows the results of the three samples.

                          Overnight           2-day           Standard             Total

Group (1)                 27                     20                   53                   100

Group (2)                32                     17                    51                    100

Group (3)                34                      19                   47                    100

Total customers     93                     56                   151                  300

We have to calculate the number of people who will use overnight delivery.

Out of 300 customer there are 93 people who would use overnight delivery, so the percentage = [tex]\frac{93}{300}[/tex] × 100 = 31%

The online store has 2755 customers one day.

Therefore, 31% of the 2755 customers = [tex]\frac{31}{2755}[/tex] × 100 = 854.05 ≈ 854 customers.

854 customers would use overnight delivery.

In a square of a side length s, what is the length of a diagonal?

Answers

s - length of a square

d - length of a diagonal

d = s√2

why?

Use the Pythagorean theorem:

d² = s² + s²
d² = 2s²
d = √(2s²)
d = √2 · √s²
d = s√2

Final answer:

The length of the diagonal in a square with side length s is s√2, calculated by using the Pythagorean theorem which relates the side lengths of a right triangle.

Explanation:

To find the length of a diagonal in a square with side length s, we can use the Pythagorean theorem. In a square, the diagonal splits the square into two right triangles. Therefore, the length of the diagonal can be seen as the hypotenuse of a right triangle where the other two sides are both of length s. The Pythagorean theorem tells us that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b).

Here is the step-by-step solution using the Pythagorean theorem:

Let the side length of the square be s.

Since the sides of the square are equal, the lengths of the two sides of the right triangle (formed by the diagonal) are also s.

According to the Pythagorean theorem, the square of the diagonal length d is d² = s² + s².

This simplifies to d² = 2s².

Take the square root of both sides to find the length of the diagonal d = √(2s²).

Therefore, the length of the diagonal is d = s√2.

For 4: The frequency of the wave is 400 Hz

For 5: The frequency of the wave is 300 Hz

For 6: The wavelength of the wave is 0.773 m

For 7: The wavelength of the wave is 0.386 m

For 8: The wavelength of the wave is 0.625 m

For 9: The wave speed of the wave is 100 m/s

For 10: The wave speed of the wave is 50 m/s

Step-by-step explanation:

Wave speed is defined as the product of its wavelength and frequency.

Mathematically,

[tex]\text{Wave speed}=\lambda\times \nu[/tex]

where,

[tex]\lambda [/tex] = wavelength of the wave

[tex]\nu [/tex] = frequency of the wave

For 1:

We are given:

[tex]\lambda =0.30m\\\\\nu=100Hz[/tex]

Putting values in above equation, we get:

[tex]\text{Wave speed}=0.30\times 100=30m/s[/tex]

Hence, the wave speed of the wave is 30 m/s

For 2:

We are given:

[tex]\lambda =0.10m\\\\\nu=50Hz[/tex]

Putting values in above equation, we get:

[tex]\text{Wave speed}=0.10\times 50=5m/s[/tex]

Hence, the wave speed of the wave is 5 m/s

For 3:

We are given:

[tex]\lambda =0.50m\\\\\text{Wave speed}=20m/s[/tex]

Putting values in above equation, we get:

[tex]20/s=0.50m\times \nu\\\\\nu=\frac{20}{0.50}=40s^{-1}[/tex]

Hence, the frequency of the wave is 40 Hz

For 4:

We are given:

[tex]\lambda =0.20m\\\\\text{Wave speed}=80m/s[/tex]

Putting values in above equation, we get:

[tex]80/s=0.20m\times \nu\\\\\nu=\frac{80}{0.20}=400s^{-1}[/tex]

Hence, the frequency of the wave is 400 Hz

For 5:

We are given:

[tex]\lambda =0.40m\\\\\text{Wave speed}=120m/s[/tex]

Putting values in above equation, we get:

[tex]80/s=0.20m\times \nu\\\\\nu=\frac{120}{0.40}=300s^{-1}[/tex]

Hence, the frequency of the wave is 300 Hz

For 6:

We are given:

[tex]\nu =440Hz\\\\\text{Wave speed}=340m/s[/tex]

Putting values in above equation, we get:

[tex]340/s=\lambda\times 440\\\\\lambda=\frac{340}{440}=0.773m[/tex]

Hence, the wavelength of the wave is 0.773 m

For 7:

We are given:

[tex]\nu =880Hz\\\\\text{Wave speed}=340m/s[/tex]

Putting values in above equation, we get:

[tex]340/s=\lambda\times 880\\\\\lambda=\frac{340}{880}=0.386m[/tex]

Hence, the wavelength of the wave is 0.386 m

For 8:

We are given:

[tex]\nu =400Hz\\\\\text{Wave speed}=250m/s[/tex]

Putting values in above equation, we get:

[tex]250/s=\lambda\times 400\\\\\lambda=\frac{250}{400}=0.625m[/tex]

Hence, the wavelength of the wave is 0.625 m

For 9:

We are given:

[tex]\lambda =2.0m\\\\\nu=50Hz[/tex]

Putting values in above equation, we get:

[tex]\text{Wave speed}=2.0\times 50=100m/s[/tex]

Hence, the wave speed of the wave is 100 m/s

For 10:

We are given:

[tex]\lambda =0.50m\\\\\nu=100Hz[/tex]

Putting values in above equation, we get:

[tex]\text{Wave speed}=0.50\times 100=50m/s[/tex]

Hence, the wave speed of the wave is 50 m/s

A passenger train and a freight train leave San Jose at 3 p.m., traveling in the same direction. The passenger train is going three times as fast as the freight train. At 6 p.m. they are 240 miles apart. How fast is each travelling?

PLEASE HELP!!!

Answers

To figure this out you could use trial and error. I started with trying 60 mph for the freight train which means the passenger train would go 180 mph. This gave me too big of a difference (540-180 after they each travel three hours).

Then I tried 50 mph and 150 mph, and it was still too big(450-100).

When I did 40 mph it was 120 travel miles for the freight train, and 360 travel miles for the passenger train. This was the difference of 240 miles that was needed.

So the freight train traveled 40 mph and the passenger train traveled 120 mph.

passenger was 120 and freight was 40

Which is C= 100w/l solved for w?
A.)W=100CL
B.)W= LC/100
C.)W= 100C/L
D.)W= 100/LC

Answers

[tex] C = \dfrac{100w}{L} [/tex]

w is on the right side multiplied by 100/L.

[tex] C = \dfrac{100}{L} \times w [/tex]

Now multiply both sides by the reciprocal of 100/L,
which is L/100, to isolate w.

[tex] C \times \dfrac{L}{100} = \dfrac{L}{100} \times \dfrac{100}{L} \times w [/tex]

[tex] \dfrac{CL}{100} = w [/tex]

[tex] w = \dfrac{CL}{100} [/tex]

[tex] w = \dfrac{LC}{100} [/tex]

Answer: choice B.

Final answer:

To solve for 'w' in the equation C = 100w/l, multiply both sides by 'l' and then divide by 100, resulting in 'w = Cl/100', which is option B.

Explanation:

To solve the equation C = 100w/l for w, we need to isolate w on one side of the equation:

Multiply both sides by l to get Cl = 100w.

Divide both sides by 100 to isolate w, which gives us w = Cl/100.

Therefore, the equation solved for w is w = Cl/100, which corresponds to option B.) W = LC/100.

Answers

the answer isn't reasonable. the actual circumference is 15.386

The circumference of circle is given by :

[tex] C =2\pi r [/tex]

where r is radius of circle and pi =3.14

Radius = half of diameter

Radius = (1/2) *4.9 = 2.45 in.

Now let us plug the value of radius in the formula for circumference.

[tex] C =2(3.14)(2.45) [/tex]

C = 15.386 inches

But circumference found by Nadiyah is 20 inches.

A can of juice has a diameter of 6.6 centimeters and a height of 12.1 centimeters. What is the total volume of a six pack of juice cans

Answers

If it is a cylindrical can then we will use the formula (pi)(r)^2(h)

Volume of one can : (3.14)(3.3)^2(12.1)
                               : 413.75

Volume of 6 cans = 413.75 * 6 = 2482.53

To find the total volume of a six-pack of juice cans, calculate the volume of one can using the cylinder volume formula, [tex]V = \pi r^2h[/tex], and multiply by six. One can's volume, with a diameter of 6.6 cm and a height of 12.1 cm, is approximately 414.18 [tex]cm^3[/tex]. Multiplying by six gives a total volume of approximately 2485.08 [tex]cm^3[/tex] for the six-pack.

To calculate the total volume of a six-pack of juice cans, we first need to find the volume of a single can and then multiply that by six, since a six-pack contains six identical cans.

First, let's find the volume of one can using the formula for the volume of a cylinder [tex]V = \pi r^2h[/tex], where r is the radius and h is the height.

Given the diameter of a juice can is 6.6 centimeters, the radius r is half of that, which is 3.3 centimeters. The height h is 12.1 centimeters. Therefore, the volume of one can is:

[tex]V = \pi (3.3 cm)^2(12.1 cm) = \pi (10.89 cm^2)(12.1 cm) = \pi (131.769 cm^3) = 414.18 cm^3[/tex]

Now, to find the total volume for a six-pack, we multiply the volume of one can by six:

Total volume = 6 × 414.18 [tex]cm^3[/tex] ≈ 2485.08 [tex]cm^3[/tex]

Thus, the total volume of a six-pack of juice cans is approximately 2485.08 cubic centimeters.

John has 8/9 of a gallon of apple cider vinegar. If it takes 1/7 of a gallon of vinegar to make a batch of collard greens, how many batches can john make?

Answers

1/7 gallon  = 1 batch 

[multiply by 7 through]
1 gallon = 7 batches

[multiply by 8/9 through]
8/9 gallon = 7 x 8/9
8/9 gallon = 6 2/9 

[Good enough to make 6 batches, not enough to make 7 batches]

So he can make 6 batches of collard green


John can make 6 whole batches of collard greens with 8/9 of a gallon of apple cider vinegar, accounting for each batch requiring 1/7 of a gallon of vinegar.

The question asks how many batches of collard greens John can make with 8/9 of a gallon of apple cider vinegar, considering that each batch takes 1/7 of a gallon.

To find the answer, divide the total amount of vinegar John has by the amount of vinegar required for one batch:

Total amount of vinegar John has: 8/9 gallon

Amount of vinegar required for one batch: 1/7 gallon

Now, we use division to find out how many batches can be made:
(8/9),  (1/7)

Multiply the first fraction by the reciprocal of the second fraction: (8/9) * (7/1)

Simplify the multiplication: (8 * 7) / (9 * 1)

Calculate the result: 56/9

Finally, we determine how many whole batches John can make, since partial batches are generally not considered. As 56/9 is equal to 6 with a remainder, John can make 6 whole batches of collard greens.
