Delia has 3 5/8 yards of ribbon. About how many 1/4 yard-long pieces can she cut?

Maurinko [17]

Answer

$Find\ out\ how\ many\ \frac{1}{4}\ yard-long\ pieces\ can\ delia\ cut .$

To prove

$Let\ us\ assume\ that\ the \ \frac{1}{4}\ yards\ pieces\ cut\ be\ x.$

As given

$Delia\ has\ 3\frac{5}{8}\ yards\ of\ ribbon.$

i.e

$Delia\ has\ \frac{29}{8}\ yards\ of\ ribbon.$

Than the equation becomes

$\frac{29}{8} = \frac{x}{4}$

$\frac{29\times 4}{8} = x$

$\frac{29}{2} = x$

x = 14.5

$Therefore\ the \ \frac{1}{4}\ yards\ pieces\delia\ cut\ be\ 14 .$

2(x -9) = 9 divided ( - 1/3) what value of x makes the equation true plsss help :)))

Ivanshal [37]

Answer:

x = -9/2

Step-by-step explanation:

1. Divide 9 by -1/3:

$\frac{9}{1}$ ÷ $-\frac{1}{3}$ = $\frac{9}{1}$ · $-\frac{3}{1}$

= -27

2. Divide both sides by 2:

2(x - 9) = -27

$\frac{2(x-9)}{2} = \frac{-27}{2}$

(x - 9) = $-\frac{27}{2}$

3. Add 9 to both sides:

x = $-\frac{9}{2}$

(or 4.5 if you need it in decimal form)

hope this helps!

Multiply and simplify: sq rt 7x ((sq rt x)-7sq rt. 7)

jarptica [38.1K]

7x(√x - 7√7) Multiply √7x to "√x" and "-7√7" respectively:
√7x*√x - 7√7*√7x
First is to simplify: √7x² - 7√7²x
Extract the squares: x√7 - 7*7√x

Then, we simplify: x√7 - 49√x
After simplifying the equation, I got the answer x√7 - 49√x.

Oksana_A [137]

Answer:

Given:

Suppose Paul receives a 6% raise every year.

To find:

After four such raises, the total percentage increase to the nearest whole percent.

The formula used to calculate percentage is: (value/total value)*100%.

Step-by-step explanation:

Step 1 of 1

Assume his salary is originally 100 dollars.

Then, in the next year, he would have 106 dollars, and in the next, he would have 112.36 dollars.

The next year he would have 119.1016 dollars and in the final year, he would have 126.247.

As the total increase is,

((126.247 -100)/100) *100

= 26.247%

the answer is 26%.

Answer:

4,756.66 seconds or 1.321 hours

Here's how I got that:

- Simply use time formula and plug in what you know -

t = distance/speed

↓

1,427,000,000,000/300000000

↓

t = 4,756.66

~That's all folks~
