Answer:

1 2/3

Step-by-step explanation:

If you do the things in the order which would be 2/6*4 (because that is how the order of operations would be) that equals 1 1/3 in fractions. So to get to B, you need to find what equals 3 so you would do 3- 1 1/3 and that would give you 1 2/3.

3=2/6*4+b

3=4/3+b

3-4/3=b

B=2 2/3

1. Y varies inversely with x. If y = 9 when x = -5, find the value of x when y=-6.

Gelneren [198K]

Answer:

Step-by-step explanation:

1 ) Y∝ 1 / X

Y = k / X

Y = 9 , X = -5

Putting the values in the relation above

9 = k / - 5

k = -45

Y = - 45 / X

Put Y = - 6

- 6 = - 45 / X

X = - 45 / -6

= 7.5

Luke and Nora can peel 12 carrots in 5 minutes

in 1 minute Luke and Nora can peel 12 / 5 carrot

in 1 minute Luke alone can peel 12/ 11 carrot .

In 1 minute Nora alone will peel (12 / 5 - 12/ 11 ) carrot

(12 / 5 - 12 / 11 )

= 2.4 - 1.1

= 1.3 carrot

In 1 minute Nora alone will peel 1.3 carrot

1.3 carrot in 1 minute

8 carrot in 8 / 1.3 minute

= 6.15 minutes.

In 1 minute Nora alone will peel 8 carrot in 6.15 minutes working alone.

Last question! I need help with showing my work! I already have the answer in the attached image below, thanks!

Rainbow [258]

Answer:

see explanation

Step-by-step explanation:

Given

$\sqrt{\frac{4x^2}{3y} }$

= $\frac{\sqrt{4x^2} }{\sqrt{3y} }$

= $\frac{2x}{\sqrt{3y} }$

Rationalise the denominator by multiplying the numerator/ denominator by $\sqrt{3y}$

Note that $\sqrt{a}$ × $\sqrt{a}$ = a

= $\frac{2x}{\sqrt{3y} }$ × $\frac{\sqrt{3y} }{\sqrt{3y} }$

= $\frac{2x\sqrt{3y} }{3y}$

Steven, a tailor, got an order to make a blazer. The customer specifically asked him to save 5⁄6 of a foot of the given cloth to

xz_007 [3.2K]

To answer this question, we just need to subtract the saved cloth from the requested cloth:

$\frac{5}{6} - \frac{5}{12}$

Since the fractions don't have the same denominator, we have to find the least common denominator. Luckily, since 6 goes into 12 twice, we can convert $\frac{5}{6}$ into $\frac{10}{12}$ :

$\frac{5}{6}( \frac{2}{2}) - \frac{5}{12} = \frac{10}{12} - \frac{5}{12}$

Now that the fractions have a common denominator, we can subtract them:

$\frac{10}{12} - \frac{5}{12} = \frac{5}{12}$

The difference between the requested cloth and the saved cloth is 5/12 of a foot, or 0.4166'.

ANSWER BOTH!!!

Answer:

A = $52.00
B = $6.30

Step-by-step explanation:

<h3>A. How much Bill paid AFTER the discount.</h3>

Step 1: Convert the discounted percent to decimal

20% = 0.2

Step 2: Multiply the discount to the item regularly priced

0.2(65.00) = 13

So, Bill received a $13 discount, therefore, the amount he paid AFTER his discount is:

Step 3: Subtract the result (the discount Bill received) from the regular price

$65.00 - $13.00= $52.00

Therefore, Bill paid $52.00

<h3>B. The price of the pillow in the department store.</h3>

Step 1: Multiply the wholesale price for a pillow by the marked-up the wholesale price

$4.50 × 40% = 1.8

Set up a fraction

$\frac{4.50}{x}=\frac{100\%}{40\%}$

The reciprocal of both sides gives

$\frac{x}{4.50}=\frac{40}{100}$

x = 1.8

Step 2: Add the result to the wholesale price for the pillow

4.50 + 1.8 = $6.3

Step 3: Round to the nearest cent

Add a zero behind the result = 6.30

Therefore, the price of the pillow in the department store is $6.30
