What is the quotient of 15p^-4 q^-6/-20p^-12 q^-3 in simplifed form?

Answers

In this question, you have two variable p and q. To simplify it, you need to divide each variable which will result in subtracting the power/exponent. Since all the exponent is a minus, it will be easier to switch the position first. The calculation should be:

15 * p^-4 * q^-6 / -20 * p^-12 * q^-3=
15 * p^12 * q^3 / -20 * p^4 * q^6=
15 /-20 * p^(12-4) * q^(3-6)=
-3 /4 * p^8 * q *-3=
-3 * p^8/ q^3

Ben has collected one more marble than three times the number of marbles as jerry. together they have 229. how many marbles does ben have?

Answers

Working backwards, we first subtract 1. That is 228. Next you divide 228 by 4, which is how many parts they have in all. That is 57. 57 times 3 is how much ben has. Your answer is 171.

Final answer:

To find out the number of marbles Ben has, we set up equations based on the information given, solve for Jerry's marbles (J), and then use that to solve for Ben's marbles (B). Ben has 172 marbles.

Explanation:

Let's denote the number of marbles Jerry has as J, and the number Ben has as B. According to the problem, Ben has one more marble than three times the number of marbles Jerry has, so we can write this relationship as B = 3J + 1. Together, Ben and Jerry have a total of 229 marbles, which gives us the equation B + J = 229.

Now, we can substitute the expression for B from the first equation into the second equation to solve for J:

3J + 1 + J = 2294J + 1 = 2294J = 229 - 14J = 228J = 228 / 4J = 57

Now that we know Jerry has 57 marbles, we can find out how many marbles Ben has:

B = 3(57) + 1B = 171 + 1B = 172

Therefore, Ben has 172 marbles.

A home improvement store advertises 60 square feet of flooring for $287.00 including an $80.00 installation fee. Write in equation to represent the cost of one square foot of flooring.

Answers

Hello there,
60 square feet= $287.00 + $80.00
= $367
1 square feet= $367 / 60
= $6.116666667
= $6.12 (to 2dp)

Hope this helps :))

~Top

The cost of one square foot of flooring (excluding the installation fee) can be calculated by subtracting the installation fee from the total cost and then dividing by the total square feet. The equation for this would be c = ($287 - $80) / 60. Solving this equation yields a cost of $3.45 per square foot.

The total cost for a flooring, including the installation fee, is $287. This cost is for 60 square feet of flooring. Therefore the cost c for one square foot of flooring can be calculated using the equation c = (Total Cost - Installation Fee) / Total Square Feet. To find this, subtract the installation fee from the total cost and then divide the remainder by the total square feet. This gives us the equation c = ($287 - $80) / 60. Solving this equation, we find that c = $3.45. So, the cost per square foot of flooring, excluding the installation fee, is $3.45.

-3 3/8 - 7/8 in simplest form

Answers

First, you would want to make -3 3/8 an improper fraction. To do that you would multiply the denominator by the whole number, then add that number to the numerator. That would make the improper fraction -27/7. You would then subtract 7/8 from -27/8 which would make the answer -34/8. Then simplifying it you would get -4 1/4.

Which table shows s decreasing linear relationship

Answers

B; usually anytime there are negative numbers, 9 times out of 10 the line is decreasing

The decreasing linear relationship is shown in table 1. The correct option is A.

What is a linear relationship?

The linear relation is defined as the variation of the variables by a constant factor with the different values of variables x and y.

The given table is,

X Y

4 10

7 17

10 18

13 22

The linear relation will be calculated as:-

y = kx

k = y / x

k = 10 / 4 = 2.5

k = 17 / 7 = 2.42

k = 18 / 10

k = 1.8

k = 22 / 13 = 1.69

The slope will be,

m = ( 17 - 10 ) / ( 7 - 4 ) = 7 / 3

Therefore, table 1 depicts the decreasing linear relationship. A is the correct answer.

A record album is 3/16 of an inch thick. How many albums can be stacked to fit in a box 12 inches high? Please show me how you got you answer explain

Answers

Final answer:

In order to find out how many albums will fit in the box, divide the total height of the box by the thickness of one album. This resulted in a total of 64 albums.

Explanation:

The problem involves determining the number of record albums that can be stacked into a box with a height of 12 inches. Each album is 3/16 of an inch thick. To find the number of albums, you will need to divide the total height of the box, which is 12 inches, by the thickness of one album.

Here is the calculation: 12 ÷ (3/16) = 12 ÷ 0.1875 = 64.

Therefore, you can fit 64 albums in a 12-inch high box. Remember, this involves simple division and understanding of fractions and their decimal equivalents.

The price of an antique book is $91,which is two-fifth more then the cost to the book dealer.Find the cost.

Answers

Let the price of book x. That's the cost the book dealer.

He wants to earn some money while selling it, so he listed the book by a new price, 91 $

He added two-fifth (2/5) price to its initial price. In other words, its new price is 40 % more expensive. (2/5 = x /100)

Here is the equation in words,
initial price + 2/5 of the initial price = 91

by equation: x + 2/5 x =91

multiply both sides by 5, to eliminate the denominator:

5x +2x = 91.5 ; 7x = 455

divide both sides by 7 to simply coefficient of x: x= 65

The answer is 65$.

Answer:

The cost to book dealer is $65

Step-by-step explanation:

Given : The price of an antique book is $91.

The price is two - fifth more than the cost to book dealer.

To Find : Cost.

Solution :

Let the cost to book dealer be x

The price of an antique book is $91.

Two - fifth of the dealer cost : [tex]\frac{2}{5}x[/tex]

Since we are given that price is two - fifth more than the cost to book dealer.

⇒[tex]x+\frac{2}{5}x=91[/tex]

⇒[tex]\frac{7}{5}x=91[/tex]

⇒[tex]x=\frac{91*5}{7}[/tex]

⇒[tex]x=\frac{455}{7}[/tex]

⇒[tex]x=65[/tex]

Hence , The cost to book dealer is $65
