Answer:

$5^-7, 5^0, 5^4$

Step-by-step explanation:

Any time a number has a negative exponent that means that the resulting number will be a fraction (ex. $2^-2=\frac{1}{4}$ ). Therefore this number is the smallest number.

Anytime a number has an exponent of 0, it will always equal 1

An airplane flies 2700 miles to Los Angeles to NYC. When the plane flies back to LA, is it flying in a negative direction? use a

dolphi86 [110]

Answer:

Distance = abs(-1700)

Distance = 1700 miles

Step-by-step explanation:

NYC is located East of Los Angels.

The Airplane flies from Los Angeles to the left direction from NYC.

Which is negative direction.

Therefore, distance = -1700

Here the distance cannot be negative even though if it flies in negative direction.

Therefore, we use the absolute value.

The absolute value of a number is always positive.

So, distace = abs( -1700)

Distance = 1700 miles.

Hope this will help you understand the concept.

Thank you.

Angelo brought apples and bananas at the fruit stand. He bought 20 pieces of fruit and spent $11.50 apples cost $.50 and bananas

Jlenok [28]

Angelo bought 14 apples and 6 bananas

Solution:

Let "a" be the number of apples bought

Let "b" be the number of bananas bought

Cost of 1 apple = $ 0.50

Cost of 1 banana = $ 0.75

He bought 20 pieces of fruit. Therefore,

number of apples bought + number of bananas bought = 20

a + b = 20 -------- eqn 1

He spent $ 11.50. Therefore, we frame a equation as:

number of apples x Cost of 1 apple + number of bananas x Cost of 1 banana = 11.50

$a \times 0.50 + b \times 0.75 = 11.50$

0.50a + 0.75b = 11.50 ------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

a = 20 - b ------ eqn 3

Substitute eqn 3 in eqn 2

0.50(20 - b) + 0.75b = 11.50

10 - 0.5b + 0.75b = 11.50

0.25b = 11.50 - 10

0.25b = 1.5

Divide both sides of equation by 0.25

Substitute b = 6 in eqn 3

a = 20 - 6

Thus he bought 14 apples and 6 bananas
