Mathematics
1 answer:
Dima020 [189]3 years ago

Its like
a*(b + c) = [a*b + a*c]
or (b + c)*a = [b*a + c*a]
let 18 = 8 + 10, here b = 8 & c = 10, & a = 3
writing it like (8 + 10)*3 = [8*3 + 10*3] = 24 + 30 = 54.

If John pays $144 for 9 pounds of pears, how much is each pound
Artist 52 [7]

Answer:

$16 per pound

Step-by-step explanation:

We want to find the price per pound.

Therefore, we must divide the cost by the pounds.

\frac{cost}{pounds}

We know it costs $144 for 9 pounds of pears. Therefore, $144 is the cost and there are 9 pounds.

\frac{\$144}{9 pounds}

Divide.

\$16 /pound

It costs $16 for each pound of pears.

<h3>Answer:  25w+200 > 750</h3>

==========================================================

Explanation:

He starts off with 200 cards. Then he adds on 25w more cards for each week (w). Overall, he'll have 200+25w cards

We can think of it like this:

  • After 1 week, he adds on 25*1 = 25 cards
  • After 2 weeks, he adds on 25*2 = 50 cards total
  • After 3 weeks, he adds on 25*3 = 75 cards total
  • After 4 weeks, he adds on 25*4 = 100 cards total, and so on.
  • After w weeks, he adds on 25w cards total

So that's another way to see where the 25w comes from.

The expression 200+25w is the same as 25w+200. This is because we can add two numbers in any order.

------------

Since he wants to know when he'll have more than 750 cards, this means we set 25w+200 greater than 750.

That's how we get to the answer of 25w+200 > 750

Notice how there isn't a line under the inequality sign. We aren't using the "greater than or equal to" symbol here. We want to know when the cards gets over 750, but we don't want to know when it's equal to 750.

What is the value, after 7 years, of a 2014 Ford Mustang that originally costs $25,000.00 if it depreciates at a rate of 8% per
Sholpan [36]
The value would be $14,000.

The formula we use for this is

A = p(1+r)ˣ, where p is the initial value, r is the percent of depreciation (as a decimal number) and x is the number of years.  Note that since it is depreciation, r will be a negative number.

A = 25000(1-0.08)⁷ = 13946.17 ≈ 14000
