Evaluate. Express your answer in exact simplest form.
kumpel [21]

Answer:

6720

Step-by-step explanation:

The writing 8P5 represents the number of permutations of 8 elements  taken 5 at a time.

<u></u>

<u>First Method</u> :

8P5 = 8 × 7 × 6 × 5 × 4

       = 6720

<u>Second Method</u> :

8P5=\frac{8!}{\left( 8-5\right)!}

=\frac{8!}{ 3!}

=\frac{8 \times 7 \times 6 \times 5 \times 4 \times 3!}{ 3!}

= 8 \times 7 \times 6 \times 5 \times 4

= 6720

Multiplying and Dividing by Powers of 10 When multiplying a number by 10, move the decimal to the right. When multiplying a numb
just olya [345]

Answer:

Because we actually divide by 10 when a number is multiplied by 0.1.

Step-by-step explanation:

Let a be a number.

When we multiply a number by 10:

a \times 10 = 10 a (One '0' is increased in the number)

For example:

23 \times 10 = 230

Considering a decimal number:

2.3 \times 10 = 23

Multiplying a number with 0.1 (which is actually \frac{1}{10}) means dividing the number by 10.

23\times 0.1 =23\times \frac{1}{10}=2.3

Considering a decimal number:

2.3 \times 0.1 = 2.3 \times \frac{1}{10} = 0.23

<em>Therefore, When multiplying a number by 0.1, move the decimal to the left.</em>

Harper has $15.00 to spend at her grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers
Andrej [43]
First write the inequality:    15\leq4.75x +3.50

Then to solve, first subtract 3.50 from both sides to get:

11.50\leq4.75x

Then divide by 4.75 to get 2.42, and since you can't buy .42 of a bag  of fruit, you round down. So your final answer would be 2 bags of fruit.
