Write the expression using only positive exponents. Assume no denominator equals zero. I will give brainliest!

Answers

Answer 1

The answer is x^13/y^3. You subtract the exponents when you divide, so:

x^10- x^-3 and y^4-y^7. Since, with the x's, you are subtracting a negative, they cancel out, and it's the same as adding a positive: giving you x^13 in the numerator. Subtracting the y's exponents gives you y^-3. Since this is a negative exponent, you put it into the denominator to make it positive. In the end, you get:

x^13 / y^3. Hope this helps!

The means and mean absolute deviations of the amount of rain that fell each day in a local city, last week and this week, are shown below. Means and Mean Absolute Deviations of Rainfall Last Week and This Week Last Week This Week Mean 3.5 in. 2.7 in. Mean Absolute Deviation 1.2 in. 0.5 in. Which expression compares the difference of the two means to this week’s mean absolute deviation?

(A) 0.8/0.7
(B) 2.7/0.7
(C) 0.8/0.5
(D) 2.7/0.5

Answers

Given:
Last Week This Week
Mean 3.5 in. 2.7 in.
Mean Absolute Deviation 1.2 in. 0.5 in

If this is what the table looks like, my answer is (C) 0.8/0.5

The difference of the two means to this week’s mean absolute deviation is?

The two means are 3.5 in and 2.7 in. The difference would be 3.5 - 2.7 = 0.8
This weeks' mean absolute deviation is 0.5 in according to the table.

So, 0.8 / 0.5 is the answer.

suppose robbie buys x scones then according to the question.....cameron will have x+y
..lou's will have (x+y)+y=x+2y ...
Tom=x+3y....

We can separate this into a rectangle and a triangle and then find the areas of these shapes separately. The triangle has a height of 9 - 5 = 4 inches, and a base of 6 inches. The rectangle will have a width of 4 inches and a length of 5 inches. Use the formulas to find the areas of these shapes and then combine them to find the area of the entire arrow:

Triangle:

[tex]\sf A=\dfrac{1}{2}bh[/tex]

[tex]\sf A=\dfrac{1}{2}(6)(4)[/tex]

[tex]\sf A=12~in^2[/tex]

Rectangle:

[tex]\sf A=lw[/tex]

[tex]\sf A=(5)(4)[/tex]

[tex]\sf A=20~in^2[/tex]

Michael needs to wrap a gift that is shaped like a triangular pyramid. Each face has an area of 25 in². What is the surface area? (Hint: Figure out how many faces a triangular pyramid has)

If the answer is 75 ft², color is black if the answer is 100 in², color is red

Answers

A triangular pyramid is a pyramid having a triangular base. It has 4 faces, 6 edges and 4 vertices.

Since the area of one face is 25 [tex] in^{2} [/tex]

Therefore, surface area of triangular pyramid = 4 [tex] \times [/tex] area of one face

= [tex] 25 \times 4 [/tex]

= 100 [tex] in^{2} [/tex].

So, the surface area of triangular pyramid is 100[tex] in^{2} [/tex].

Therefore, color is red.

Vicki has 210 baseball cards and buys an additional 15 cards every week. Jeb has 275 baseball cards and buys an additional 10 cards every week. After how many weeks will Vicki and Jeb have the same number of baseball cards?

Answers

It will be after 13 weeks.

Answer:

After 13 weeks, Vicki and Jeb will have the same number of baseball cards.

Step-by-step explanation:

Let n be the required number of weeks after which Vicki and Jeb have the same number of baseball cards.

The number of cards Vicki will buy after n weeks = 210 + 15n

The number of cards Jeb will buy after n weeks = 275 + 10n

Since, these are equal,

210 + 15n = 275 + 10n

15n - 10n = 275 - 210

5n = 65

Divide both sides by 5.

n = 13.

Hence, after 13 weeks, Vicki and Jeb will have the same number of baseball cards.

I believe your answer is 325/1.

Work:

Area = L x W
13 x 25 = 325

Answer:

325/100 = 13/4 or 31/4

Step-by-step explanation:

25 is a common factor of both 325 and 100, so divide numerator and denominator by 25 and you get 13/4, which can be written as 3 and 1/4 or 3.25 in decimal

This is because it said simplest form.

Now that you have converted a terminating decimal number into a fraction, try converting a repeating decimal number into a fraction. Repeating decimal numbers are more difficult to convert into fractions. The first step is to assign the given decimal number to be equal to a variable, . For the decimal number , that means . If , what does 10x equal?

Answers

The first step is to assign the decimal number to a variable.

For the repeating fraction 0.111_1, this would look like
.. x = 0.111_1 . . . . . . . . . . where we use an underscore to identify the following digit(s) as repeating

The next step is to multiply that value by 10 to a power equal to the number of repeating digits. If there is one repeating digit (as here), then you want (10^1)x = 10x.
.. 10x = 1.111_1

The third step is to subtract x from this.
.. 10x -x = 1.111_1 -0.111_1 = 1
.. 9x = 1

And the final step is to divide by the coefficient of x.
.. x = 1/9 . . . . . . this is the value of the repeating decimal fraction.

_____
Here's one that's a little more complicated. It is done the same way.
.. x = 3.254545_45
.. 100x = 325.454545_45
.. 100x -x = 99x = 322.2
.. x = 322.2/99 = 3222/990 = 179/55

Answers

To solve this, we need the formula for the volume of a sphere. The formula is expressed as the 4/3 of the product of the cube of the radius and pi.Volume = 4/3 (π x r^3)
Substituting the given values, we have:
Volume = 4/3 (3.14 x 21^3)Volume = 38772.720 cm^3
Thus, the approximate volume of the container is 38772.720 cm^3.

drag correct circle to box. first circle is not a solution. it is extra

Answer:

1/9, 1/8 and 1/4

Step-by-step explanation:

multiply the both given numerators (top numbers) and both given denominators (bottom numbers) given bellow

1/3 x 1/3 = 1/9 because 1 x 1 = 1 and 3 x 3 = 9

1/4 x 1/2 = 1/8 because 1 x 1 = 1 and 4 x 2 = 8

3/4 x 1/3 = 3/12 or 1/4 simplified because 3 x 1 = 3 and 4 x 3 = 12. when you simplify you divide the denominator by the numerator and 12 divided by 3 is 4 and you the 4 stays as the denominator and make the numerator of 1

If x < 5 and x > c, give a value of c such that there are no solutions to the compound inequality. Explain why there are no solutions

Answers

The value of c could be 5 or any number greater than 5.

The solution is the intersection of both solution sets of the given inequalities.

The solutions of the compound inequality must be solutions of both inequalities.

A number cannot be both less than 5 and greater than 5 at the same time.

Final answer:

To ensure there are no solutions to the compound inequality x < 5 and x > c, we can choose c to be 5 or larger, such as c = 6, making the inequality impossible.

Explanation:

To determine a value of c such that the compound inequality x < 5 and x > c has no solutions, we need to choose a value of c that makes the inequality impossible to satisfy.

One way to ensure there are no solutions is to choose c so that it is greater than or equal to 5.

If c is 5 or any number larger than 5, then there is no real number x that can be both greater than c and at the same time less than 5.

For example, if we choose c = 6, then the set of values greater than 6 (x > 6) does not intersect with the set of values less than 5 (x < 5).

Therefore, c = 6 would ensure that there are no solutions to the compound inequality.
