Answer:

530.3

Step-by-step explanation:

You want to subtract 620-89.7. If you want to use the standard algorithm you have 620.0-89.7. You "borrow" from the 2 in the tens place, then "borrow" from the ones place. To subtract 10-3 tenths. Then you subtract the ones place which is 9-9=0 ones. Now you subtract 62-8=53 tens. So you have 530.3 as the difference.

Anybody can help? (Here's a pfp)
Tasya [4]

First make a guest check

My Guest check #9

1 donut = $1.29

Donut holes = $4.89

Dozen Donuts = $12

Donut Holes = $4.89

$1.29 + $4.89 + $12 + $4.89 = $23.07

$23.07 * 8% =<em> $24.92 is the 9th check list</em>

My Guest check #10

1 donut = $1.29

1 donut = $1.29

Dozen Donuts = $12

Donut Holes = $4.89

$1.29 + $1.29 + $12 + $4.89 = $19.47

$19.47 * 8% = <em>$21.03 is the 10th check list</em>

If the mean of 5 positive integers is 15, what is the maximum possible difference between the largest and the smallest of these
igomit [66]

Answer:

64

Step-by-step explanation:

If the mean is 15, the sum of 5 numbers is:

  • 5*15 = 75

Minimum value for the first four numbers would be:

  • 1, 2, 3, 4

Then the fifth number is:

  • 75 - (1+2+3+4) = 75 - 10 = 65

So the maximum difference is:

  • 65 - 1 = 64

A rectangular yard is fenced in using 319 feet of custom fence Your friends really like the fence and decide to fence in their y
Vsevolod [243]

We have been given that a rectangular yard is fenced in using 319 feet of custom fence Your friends really like the fence and decide to fence in their yard using the same fence.  Their yard is similar but has a scale factor of 8/5 times the size of  yours.

We are asked to find the length of fence that your friends should purchase.

Since the size of your friend's yard is \frac{8}{5} times your yard, so your friend should purchase \frac{8}{5} times the 319 feet.

\text{Length of fence your friend should purchase}=\frac{8}{5}\times 319\text{ ft}

\text{Length of fence your friend should purchase}=8\times 63.8\text{ ft}

\text{Length of fence your friend should purchase}=510.4\text{ ft}

Upon rounding our answer to nearest foot, we will get:

\text{Length of fence your friend should purchase}\approx 510\text{ ft}

Therefore, your friends should purchase 510 feet of fence and option C is the correct choice.
