Multiplication and division both need to have a common denominator or else you would get an incorrect answer. Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators."

Multiplying and Dividing fractions are exactly the same. When dividing a fraction your doing the same as multiplying. Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. For example you have 1/3 divide by 4/6 you switch the sign to multiplication and switch 4/6 to 6/4. Then you multiply 1/3 and 6/4 across leaving you with 6/12, simplified to 1/2.

Dalia buys a winter jacket at a used clothing store that costs $30. She lives in Idaho, where the sales tax is 6%.




Write an equation that represents the total cost, c, of any item bought in Idaho whose price is p

Answers

Answer:

c = 0.06p + p

Step-by-step explanation:

hope this helped

An equation that represents the total cost, c, of any item bought in Idaho whose price is p is c = 1.06p.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

Cost of the winter jacket = $30

Sales tax = 6%

Total cost of the winter jacket = 30 + (6% × 30)

                                                   = 30 + 1.8

                                                   = $31.8

If the total cost of any item is c whose price is p,

c = p + (6% × p)

c = p + 0.06p

c = 1.06p

Hence the required equation is c = 1.06p.

what are the angles of a triangle with 73, x, x-11?

Answers

Answer:

The angles of the triangle are 73, 59, and 48

Step-by-step explanation:

The sum of a triangle's angles must always add up to 180

In order to find out the measure of x we must make an equation where 180=the sum of the angles

180=2x+62

We got the 2x and the 62 from combining like terms

x+x=2x

73-11=62

Now we simply use algebra and try to solo out the x

First, subtract 62 from both sides

118=2x

Then, divide both sides by 2

59=x

x=59

Then plug in 59 with x and this gives you

73, 59, and 48 which all together add up to 180

Answer:

The values that are in the correct spots are: 82, 62, 163 and 300

Step-by-step explanation:

There are 144 boys in total. We know that 82 attended the fall fling, so if we do 144-82 we know that 62 boys attended the spring social, therefore the vaules 82 and 62 are in the correct spots. We know that out of 156 girls, 75 attended the spring social. 156-75=81. The values 75 and 81 are in the wrong spots, therefore they are not correct.

82 boys + 81 girls at the fall fling = 163 total students at the fall fling, therefore 163 is also in the correct spot.

62 boys + 81 girls at the spring social = a total of 137. The chart says the total is 143 which is incorrect.

156 total boys plus 144 total girls = 300 total students, therefore 300 is in the correct spot.

Which is bigger, 1.2 or 1.18 repeating

Answers

Answer:

[tex]beinggreat78~here~to~help.[/tex]

Your answer would be that 1.2 is bigger.

Why is that the case?

This is the case because the tenths place, the decimal farthest to the left, is greater than the compared tenths place, which has a 1

1 is greater than 2

With that information, 1.2 is bigger.

Comparing the two decimal approximations, we can see that 1.2 is bigger than 1.18 repeating (1.1818).

To compare 1.2 and 1.18 repeating (1.181818...), we can first convert 1.18 repeating to a fraction.

Let x = 1.181818...

Now, multiply x by 100 to remove the repeating decimal:

100x = 118.181818...

Subtract x from 100x to eliminate the repeating part:

100x - x = 118.181818... - 1.181818...

99x = 117

x = 117 / 99

Now, we simplify the fraction:

x = 13 / 11

Now that we have both numbers in decimal form, we can compare them:

1.2 ≈ 1.2 (rounded to one decimal place)

1.18 repeating = 13 / 11 ≈ 1.1818 (rounded to four decimal places)

Comparing the two decimal approximations, we can see that 1.2 is bigger than 1.18 repeating (1.1818).

PART A

If 4 pounds = 10 dollars...

4/2 = 2

10/2 = 5

So for 2 pounds, it would cost $5.00

Now for the 1 pound one

4/1 = 4

10/4 = 2.5

For the 1 pound one, it would cost $2.50

PART B

We know that 4 pounds = 10 bucks

Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, $1 = 0.4lb

Now for the last blank...

Since $1 = 0.4, we multiply that by 9. 0.4 x $9 = 3.6lb
