Answer:

Step-by-step explanation:

Area for rectangle is A=b×h

You can only multiply radicals with other radicals so... √17×√68= √1156

Simplify radical

√1156= 34

Then add 9

34+9= 43

Answer:

Answer is 904

Refer below.

Step-by-step explanation:

5650 total,

And 4:1 which adds up and make 5. So,

5x = 5650

x=5650/5

x=1130

As pichard part is 4:1 so his part is 4 overall the money so,

Richard got 4x = 4 × 1130 = 4520

4520 now dividing in 6:3:1

10a = 4520

A= 452

Wife amount is 3a = 3 ×452 = 1356

Son is 1a so its,

Son = 452

Minus= 1356 -452 = 904

Wife got 904 more than son

it would depend how much you actually used, but you would take the amount you used and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.

Write a mixed number between 4 and 5, and then write its reciprocal.

11Alexandr11 [23.1K]

Answer:

$4\frac{1}{2}$ and it's reciprocal is $\frac{2}{9}$

Step-by-step explanation:

4.5 is a number in between 4 and 5, as a fraction it is written as $4\frac{1}{2}$ . To get the reciprocal you need to change it to an improper fraction so it becomes $\frac{9}{2}$ . The reciprocal will be 1 ÷ $\frac{9}{2}$ . This literally means the number will just invert and become $\frac{2}{9}$
