Answer:

Bella bought the t-shirt at $9.54 each.    

Step-by-step explanation:

We are given the following in the question:

"T-shirts at Perfect Tee cost either $9 or  $10 depending on the style."

Cost of 13 t-shirts = $124

We have to find the cost of each t-shirt.

Cost of 1 t-shirt =

[tex]=\dfrac{\text{Total cost of t-shirts}}{\text{Number of t-shirts}}\\\\=\dfrac{\$124}{13}\\\\=\$9.5384\approx \$9.54[/tex]

Thus, Bella bought the t-shirt at $9.54 each.

Answer:

F and I

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.  

Through which points should a line of rotation be placed to create a cylinder with a radius of 3 units?

E and J

F and I

J and G

G and E

My answer:

From the photo, we can see that:

the point F is in the middle of the length EG => EF = FG = 3 units

the point I is in the middle of the length JH and because this is a rectangle so EG = JH

=> JI = JH = 3 units

So the points should a line of rotation be placed to create a cylinder with a radius of 3 units is: F and I  where F and I are the center points of the two bases in the cylinder

Answer:

B) f(x) = -3/5x +5

Step-by-step explanation:

There are several ways you can write the equation of a line from a list of points. When you look through the list and see that one of them is the y-intercept, then the problem can be easier. When you look through the list of answers and see that the required answer is in slope-intercept form, then you know all you need to do is find the slope to go with the intercept you've located. The point (x, f(x)) = (0, 5) tells you the y-intercept is 5.The slope, the change in y divided by the change in x for two points, is ...... (-1 -2)/(10 -5) = -3/5This is the slope and the coefficient of x in the linear equation.Now, we know the y-intercept (b=5) and the slope (m=-3/5), so we can fill in the slope-intercept form of the equation of a line:... y = mx + b... y = (-3/5)x + 5

Answer:

Area of a 30-inch circular mirror is greater than area of a 18-inch circular mirror by 452.16 square inches.

Step-by-step explanation:

We are given the following in the question:

Mirror 1:

[tex]d_1 = 30\text{ inches}\\\\\Rightaroow r_1 = \dfrac{30}{2}=15\text{ inches}[/tex]

Area of mirror 1 = Area of circle

[tex]A_1 = \pi r_1^2[/tex]

Putting values, we get,

[tex]A_1 = 3.14\times (15)^2=706.5\text{ square inches}[/tex]

Mirror 2:

[tex]d_1 = 18\text{ inches}\\\\\Rightaroow r = \dfrac{18}{2}=9\text{ inches}[/tex]

Area of mirror 1 = Area of circle

[tex]A_2 = \pi r_2^2[/tex]

Putting values, we get,

[tex]A_2 = 3.14\times (9)^2=254.34\text{ square inches}[/tex]

Difference between area =

[tex]=A_1-A_2\\=706.5-254.34\\=452.16\text{ square inches}[/tex]

Thus, area of a 30-inch circular mirror is greater than area of a 18-inch circular mirror by 452.16 square inches.

Assuming original commercials were 30 seconds long, during a 3.6-minute break, 7 commercials could fit. If they are half as long, or 15 seconds each, then 14 commercials could fit in the same time period.

The question is asking to calculate how many commercials will play during a commercial break that lasts 3.6 minutes if the commercials are half as long as the ones during the original break. To calculate this, you need to know the length of the original commercials. However, since this information was not provided in the question, let's for example assume that the original commercials were 30 seconds long each (a common commercial length).

If the original commercials were 30 seconds long, then during a 3.6-minute break (which converts to 216 seconds), you could fit in 216 / 30 = 7.2, which is not possible since you can't have a fraction of a commercial. So, you would normally have 7 commercials during the break.

If the new commercials are half as long, meaning they are 15 seconds each, then during the same 3.6-minute break, you could fit in 216 / 15 = 14.4, which again is not possible, so you would have 14 commercials play during the break since you can't have a fraction of a commercial.

Answer:

nobody gave the right answers but here it is :

Step-by-step explanation:

x = −3

⇒ asymptote

x = −2

⇒ asymptote

x = 0

⇒ hole

x = 2

⇒ neither

x = 3

⇒ neither

x = 5

⇒ neither

To determine whether each value of x is a discontinuity of the function, we analyze the function to find asymptotes or holes. For the given function, x = -2 and x = -3 are asymptotes, x = 0 is a hole, and the remaining values of x do not create any discontinuities.

To determine whether each value of x is a discontinuity of the function, we need to analyze the function and look for asymptotes or holes. Let's consider the function f(x) = (5x) / (x^3 + 5x^2 + 6x).

To identify asymptotes, we need to find the values of x where the denominator of the function is equal to zero. For x = -2 and x = -3, the denominator becomes zero, which indicates that there are vertical asymptotes at x = -2 and x = -3. These values are neither holes nor asymptotes.

For x = 0, the denominator also becomes zero, but the numerator is not zero. This indicates that there is a hole at x = 0.

For the remaining values of x (2, 3, and 5), neither the numerator nor the denominator becomes zero. Therefore, these values do not create either holes or asymptotes. So the answer is:

Answer:

Hence Group A compose of the alternate Addition of  "ONE" and "THREE" units

Hence Group B Composes of alternate 22 units addition and 3 units addition.

Step-by-step explanation:

Given:

Two groups as A and B with number in certain patterns as

To Find:

What is that certain pattern in numbers?

Solution:

Group A includes the following numbers as ,

0,1,4,5,8

Here 1st number=0 then 2nd number =1

So in between this addition is 1 is present

And then 3rd number =4 and 4th number=5

so there  alternate addition of "one"(1) present

Now in 3rd and 2nd number there is addition of 3 units

And in 5th and 4 number there is addition of 3 units .

Hence this group compose of the alternate Addition of  "ONE" and "THREE" units.

Group B includes the following number as ,

10,32,35,57,79

So here 1st number is 10 and 2nd number is 32 (Addition of 22 units).

Further alternate 4th 57 and 3rd number is 35 (addition of 22 units).

For 3rd number is 35 and 2nd number is 32 (addition of 3 units)

For 6th number will be is  82 and  5th number is 79 (addition of 3 units).

Hence this group Composes of alternate 22 units addition and 3 units addition.

inal answer:

The sorting rule for the numbers in Group A and Group B is based on their units digit, where numbers that end in 0 or 5 are placed in Group B, and other numbers are in Group A.

Explanation:

The student has asked to describe the sorting rule for the numbers in two groups, Group A and Group B. Looking at Group A (0, 1, 4, 5, 8) and Group B (10, 32, 35, 57, 79), the sorting rule appears to be that numbers ending in either 0 or 5 are placed in Group B, while the others are placed in Group A.

To elaborate, we can see that:

Numbers in Group A do not end with either 0 or 5.

Numbers in Group B all end with a 0 or a 5.

This pattern suggests that the sorting rule is based on the units digit of each number.

Answer:

1. 25 times larger

2. The scale factor is 25:1

Step-by-step explanation:

Given

Let A represent the area of your swimming pool

Let a represents the area of your neighbour's swimming pool.

From the question, we understand that the area of your swimming pool is 25 times larger than the area of you neighbour's. This can be represented as follows;

A = 25 * a. --- divide through by a

A/a = 25 * a/a

A/a = 25

This means that your pool is 25 times larger than your neighbour's.

To get the scale factor, we have to convert the expression above to ratio

A/a = 25

This can be rewritten as

A/a = 25/1

By comparison the position of constraints at the left hand side to those at the right hand side of the equation

A = 25

a = 1

So,

A : a = 25 : 1

Hence, the scale factor is 25 : 1

Answer:She walk the dogs for 3 hours and then she worked 5 hours landscaping for last week

Step-by-step explanation:We call X the hours she walk the dog

so the time that she do the landscaping is (8-X)

Put into equation we have 6x+13(8-x)=83

there we have x is 3

Kaylee worked 3 hours walking dogs and 5 hours landscaping last week.

This problem is a system of linear equations which we can solve using substitution or elimination method. But let's use the substitution method for this particular problem. Let's denote the number of hours Kaylee worked walking dogs as x and the number of hours she worked landscaping as y.

So from the problem we have 2 equations:

From the first equation y = 8 - x. Substitute y in the second equation by (8 - x): 6x + 13(8 - x) = 83. By solving this equation we find x = 3 Substitute x = 3 in the first equation we find y = 5.

So, Kaylee worked 3 hours walking dogs and 5 hours landscaping last week.

Answer:

4/11 and 2/11

Step-by-step explanation:

The total number of letters in the word mathematics is 11, making the denominator 11. There are 4 vowels and 2 Ts. That is the number of possibilities for each one.

The odds of choosing a vowel followed by a 'T' from the word 'MATHEMATICS' are unfavorable, approximately 5.45%. This is calculated based on the individual probabilities of first drawing a vowel, then drawing a 'T'.

The word 'MATHEMATICS' contains 11 letters, which includes 3 vowels (A, A, and E) and 2 'T's. The scenario of drawing a vowel followed by a 'T' implies a two-step process: first drawing a vowel, then drawing a 'T'. We must consider these as two separate events.

For the first draw, the chance of drawing a vowel is 3 out of 11. If successful, then the word left is 'MTHMATICS', a total of 10 letters, 2 of which are 'T's. So the chance of drawing a 'T' on the second draw is 2 out of 10.

The total probability of both events occurring is the product of their individual probabilities. So (3/11) * (2/10) = 6/110 = 0.0545, or approx. 5.45%. This can be categorized as unfavorable odds because the percentage is quite low.

From the vertex of the quadratic equation, it is found that the maximum height of the ball is of 20 meters, given by option D.

The height of the ball, after t seconds, is given by:

[tex]h(t) = -5(x^2 - 4x + 4) + 20[/tex]

[tex]h(t) = -5x^2 + 20x - 20 + 20[/tex]

Step-by-step explanation:

Have a great day!

Final answer:

The area of the larger square is four times the area of the smaller square, as the side lengths are doubled, resulting in the area increasing by the square of the factor of increase (2^2 = 4).

Explanation:

When Marta has a square with a side length of 4 inches, and she has a second square with dimensions that are twice as large, the area of the larger square can be found by squaring the ratio of the side lengths. In this case, the larger square will have side lengths of 8 inches because they are twice as long. To determine how the area of the larger square compares to the area of the smaller square, we can use the formula for the area of a square, which is side length squared (s^2).

The area of the smaller square is 4 inches * 4 inches = 16 square inches. If we double the side length to get the larger square, its sides will be 8 inches, so its area will be 8 inches * 8 inches = 64 square inches. Therefore, the area of the larger square will be four times the area of the smaller square because 64 square inches is four times 16 square inches (4^2 = 16, which means four times more area).
