michelle bought the same fabric on 3 different occasions and recorded the data below what was the price per yard of fabric? answ
bazaltina [42]

Please consider the complete question.

Michelle bought the same fabric on 3 different occasions and recorded the data below.

Yards of Fabric         Total Cost

2.2                             $2.53

3.6                             $4.14

4.2                             $4.83

What was the price per yard of fabric?

To find the cost per yard of fabric, we will divide cost of yards by number of yards.

\text{Cost per yard}=\frac{\text{Cost}}{\text{Number of yards}}

\text{Cost per yard}=\frac{\$2.53}{2.2\text{ yards}}

\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}

Let us find cost per yard using 2nd set of data.

\text{Cost per yard}=\frac{\$4.14}{3.6\text{ yards}}

\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}

Similarly we will find cost per yard for 3rd set of data.

\text{Cost per yard}=\frac{\$4.83}{4.2\text{ yards}}

\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}

Therefore, the cost per yard of fabric is $1.15.

Jill And Jamahl are comparing their favorite number.Jill number has a prime factorization of 6 number. Jamahl has a prime factor
tatiyna
To prove that jill is wrong we just need an example of this;


2*3*5*7*11*13 = 30030 (this is the smallest number with 6 different prime numbers)

5953*5981*5987 = 2.13x10^11 (which is obviously a much bigger number)

this is enough to prove that jill is wrong

Can someone actually answer this question pls its my 3rd time posting it and ill ive gotten was wrong or answers that make no se
andre [41]

Answer:

(-2+-5) equals -7.

Because the signs are the same, we dont change it.

(3+5) equals 8. Same like the other equation, the signs are the same so we do not change it.

Now we do (-7+8) The answer will be 1. Lets use a little graph since its hard to explain.

-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8

Mark -7 anyway you want. (Circle it, draw a line under it, what ever you want.)

Now Move the line 8 times.

When you do that your line will stop at 1.

And thats how you do it.

A pair of shoes are on sale for 25% off their regular price of $180. Students at Pikesville Middle can get an additional 10% off
Nikolay [14]

Answer:

$121.5

Step-by-step explanation:

$180 × 0.25 = $45 <-- because it is a discount, we will subtract

$180 - $45 = $135 <-- price with 25% discount

$135 × 0.10 = $13.5

$135 − $13.5 = $121.5
