Mrs. Patel needs
7/8
yards of fabric to make one shirt. Mrs. Patel bought 10 1/2 image yards of fabric. How many shirts can she make?

Answers

Answer:

12 shirts

Step-by-step explanation:

I used the method keep, change, flip (KCF) to divide fractions and solve this problem.

This means Keep the first fraction, Change the division sign to a multiplication sign, and Flip the second fraction.

so keep 10 1/2, or 21/2, change sign, and flip the second fraction to 8/7.

that gives us the equation 21/2x8/7, and solving that gives us 168/14, or 168 divided by 14, so 12 shirts

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the zeros 4 and 3 - I.

f(x)=

Answers

Answer:

f(x) =  x³ - 6x² + 5x + 12

Step-by-step explanation:

Given polynomial function f(x) with:

a = 1, r₁ = 4, r₂ = 3, r₃ = -1

With the least degree it is:

f(x) = 1*(x - 4)(x - 3)(x - (-1)) =         (x² - 7x + 12)(x + 1) =          x³ - 6x² + 5x + 12

If you treat 2 friends to lunch, the 1st lunch is $12. 35, the 2nd lunch is $14. 22, and your lunch is $11. 47. You want to add a 20% tip. How much will you pay in total?.

Answers

Answer; $45.74

Explanation;
$12.35+$14.22+$11.47=$38.04
20% of $38.04=$7.70
=$45.74

The solution is

The total amount for the lunch is given by the equation A = $ 45.648

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount for the lunch be represented as A

Now , the equation will be

The amount for the first lunch = $ 12.35

The amount for the second lunch = $ 14.22

The amount for the third lunch = $ 11.47

The percentage of tip = 20 %

So , the total amount for the lunch without tip = $ 12.35 + $ 11.47 + $ 11.47

On simplifying the equation , we get

The total amount for the lunch without tip = $ 38.04

The amount of tip = total amount for the lunch without tip x percentage of tip

Substituting the values in the equation , we get

The amount of tip = 38.04 x ( 20/100 )

The amount of tip = 38.04 x 0.20

The amount of tip = $ 7.608

So ,

The total amount for the lunch A = total amount for the lunch without tip +  amount of tip

Substituting the values in the equation , we get

The total amount for the lunch A = $ 38.04 + $ 7.608

The total amount for the lunch A = $ 45.648

Therefore , the value of A is $ 45.648

Hence , the total amount is $ 45.648

7 less than 6 times a number is equal to 9 more than 4 times a number. What is the number?

Answers

Answer:

Write an equation the represents the words.

6x - 7 = 4x + 9

To solve for x (the number), isolate it from the other variables.

Subtract 9 from both sides.

6x - 7 - 9 = 4x

Combine like terms.

6x - 16 = 4x

Subtract 6x from both sides.

-16 = 4x - 6x

Combine like terms.

-16 = -2x

Divide both sides by -2.

-16/-2 = x

x = 8

The number is 8.

Hope this helps! :)

Answer:

The number is 8.

Step-by-step explanation:

Hello there!

We're given an unknown number, let's call this number n

We know that 7 less than 6 times n is equal to 9 more than 4 times n

Let's break that statement down, starting with "7 less than 6 times n"

6 times n should be 6n, since 6 * n = 6n

"7 less" means subtraction.

So "7 less than 6n" should be 6n-7

Now with "9 more than 4 times n"

4 times n should be 4n, as 4 * n = 4n

"9 more" means addition

So "9 more than 4n" should be 4n+9

The statement says that 6n-7 is equal to 4n + 9, and so when we write it as an equation:

6n - 7 = 4n + 9

Now we can solve the equation

Subtract 4n from both sides

2n - 7 = 9

Add 7 to both sides

2n = 16

Divide both sides by n

n=8

The number is 8

PS. we can substitute 8 back into the equation as n to see if it works:

6(8)-7=4(8)+9

Multiply

48-7=32+9

41= 32 + 9

41=41

It works :))

Hope this helps!

There are 196.1 million square miles on earth so subtracting 139.8 from that is 57.1 so 57.1 million square miles of earth is not covered with water

The percentage of earth that is not covered in water is given by the equation A = 29 %

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total area of earth be = 196,900,000 square miles

And , 71% of Earth’s surface is covered in water

So ,

Percentage of earth's surface covered in water = 71 %

And , area of earth covered by water = 139,799,000 square miles

Substituting the values in the equation , we get

So , the remaining percentage of earth not covered in water A = 100 - 71

On simplifying the equation , we get

Remaining percentage of earth not covered in water A = 29 %

The remaining area of earth = 0.29 x 196,900,000

Answers

Answer:

Step-by-step explanation:

These numbers aren't easily compared since they don't have the same number of digits.  Sofia's time of 13.5 seconds is less than that of the other two times, 13.524 and 13.51 seconds, but the lack of a zero after the 5 in Sofia's time is concerning.  If the other times were measured toi within a hundredth of a second, why not Sofia's time also?  Perhps her true time was 13.56 seconds, but the 0.05 was dropped.  She would be slower than the other two.  But, in the absence of helpful information, the only thing that can be said is that Sofia's time is reported to be less than either Jen and Ali.

Answers

Answer:

1 and 3/20 total, 15/20 of the fish are yellow tangs which would also be 75%.

Step-by-step explanation:

2/5 and 3/4 need to be converted into a fraction with a similar denominator. 5x4= 20, so 20 is our denominator.

To find the numerator, we need to multiply 2 by 4, which equals 8, and 3 by 5 which equals 15.

8/20 + 15/20 = 23/20 or 1 3/20

On his bike, Jason can travel 8 miles in 50 minutes.
At this rate, how far can Jason travel in 150 minutes.

Answers

Answer:

Jason can travel 24 miles in 150 minutes.

Step-by-step explanation:

8= miles. 50&150= mins

8=50.

Your trying to find how many miles Jason can travel in 150 mins. So your going to divide the new amount of minutes to the old amount.

150÷50= 3.

So since 50 can go into 150 3 full times that means you will multiply the original amount of miles by 3 to get your new amount.

3×8= 24

So, if Jason can travel 8 miles in 50 mins (8=50) Then, he can travel 24 miles in 150 mins (24=150)
