Answer:

-13

Step-by-step explanation:

This is just a matter of simplifying.

x = 8-(-4)^2-5

Let's get rid of the exponent.

x = 8 - 16 - 5

x = -13

You can check if this is correct.

The tricky part is the -(-4)^2.

You have to solve the -4^2 first, instead of the parenthesis.

Fred buys flags from a manufacturer for f dollars each and then sells the flags in his store for a 26%markup.
Mashutka [201]

Answer:

the markup is 1.26 (the amount added is .26)

1.26x (when x is the price Fred buys them for from the manufacturer)

1.26(40)

$50.40 is the retail price

50.4-40

$10.40 is the markup

Step-by-step explanation:

The 26% markup means that he is selling the flags 26% above the cost.

So, the cost would represent 100%, which is 1, and 26% of markup in decimal number is 0.26.

The price including the markup would be 1.26 as decimal or 126% as percentage.

The problem states that the cost is unknown, so we represent that with a variable x. The retail price would be 1.26x, which is 126% per flag.

Finally, if Fred paid $40 per flag, the actual retail price would be:

1.26($40)=$50.40.

With $10.40 of markup.

A roll of 100 pennies is in the shape of a right cylinder. Each penny has a diameter of 0.75 inches and a thickness of 0.04 inch
zalisa [80]

Answer:

  • (B) π(0.75/2)²(4)

Step-by-step explanation:

<u>The volume formula:</u>

  • V = πr²h

<u>Given:</u>

  • d = 0.75 in ⇒ r = d/2 = 0.75/2 in
  • h = 0.04 in

<u>The volume of each penny:</u>

  • V = π(0.75/2)²(0.04)

<u>The volume of 100 pennies:</u>

  • V = 100*π(0.75/2)²(0.04) = π(0.75/2)²(4)

Correct choice is B
