the area of a rectangular photograph is 35 square inches. If the width of the photo is 5 inches how tall is the photo

1 answer:

5 0

We know that:

Area= length*width

Plug in the stuff you know.

35= length(tall)*5

Divide both sides by 5.

7= length

The photo is 7 inches tall.

I hope this helps!

Which expressions are equivalent to (2^5)^-2

Aleonysh [2.5K]

Answer: Choice B) 2^(-10) and 1/1024

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

Explanation:

We'll use these two rules
Rule 1: (a^b)^c = a^(b*c)
Rule 2: a^(-b) = 1/(a^b)

Using rule 1 above, we can say
(2^5)^(-2) = 2^(5*(-2)) = 2^(-10)
So 2^(-10) is one of the answers

Now use rule 2 to convert 2^(-10) into...
2^(-10) = 1/(2^10) = 1/1024
so 1/1024 is the other answer

Lauren pays $19.99 for a membership fee to an online music store. Lauren buys songs from a new album at the price of $0.99 each.

sdas [7]

The right answer is Option B.

Step-by-step explanation:

Let,

Number of songs = x

Price of 1 song = $0.99

Membership fee = $19.99

Total amount paid = $21.97

According to given statement;

0.99x+19.99=21.97

Subtracting 19.99 from both sides

$0.99x+19.99-19.99=21.97-19.99\\0.99x=1.98$

Dividing both sides by 0.99

$\frac{0.99x}{0.99}=\frac{1.98}{0.99}\\x=2$

Lauren bought 2 songs.

The right answer is Option B.
