The National park service is building a 16-mile trail. They will post a sign every 1/8 mile along the trail, including one at the end. There will not be a sign posted at the beginning of the trail. How many signs will they post along the trail? Please can you show me how you got your answer please.

Answers

Answer:

128 signs will be posted along the trail

Step-by-step explanation:

From the question,

The national park service is building a 16-mile trail and they will post a sign every 1/8 mile along the trail. To determine how many signs will be posted along the trail, we will divide the length of the trail by the distance in which one sign is to be posted from another.

The length of the trail = 16 mile

The distance in which one sign is to be posted from another = 1/8 mile

Hence,

Number of signs that will be posted along the trail = 16 mile ÷ 1/8 mile

= 16 × 8/1 = 128

Number of signs that will be posted along the trail = 128

This includes the sign that will be posted at the end of the trail.

Since there will not be a sign posted at the beginning of the trail, then

128 signs will be posted along the trail.

May bought groceries for $20.00 and four board games. Mai paid $108.00 for the entire purchase. How much did Mai pay for one board game?
A. $44.00
B. $22.00
C. $20.00
D. $108.00

Answers

Answer:

She paid it for 22 dollars.

Step-by-step explanation:

First, let's subtract 20 from 108 since we know Mai bought this in total.

108 - 20 = 88

Then, let's divide by 4 because we know there are 4 board games in total.

88/4 = 22.

This means that she paid 22 dollars for it. I hope this helps, I hope it's not wrong, but I don't think it is.

Which expression is equivalent to the given polynomial expression?
13p – 3p(1 – 2m) – m(2m – 5p) – m2

Answers

Answer:-3m^2+11mp+10p

Step-by-step explanation:

The equivalent expression is:

-3m² + 11mp + 10p

Hence the correct option is 2.

Given is polynomial expression 13p – 3p(1 – 2m) – m(2m – 5p) – m², we need to find an equivalent expression to it,

To simplify the given polynomial expression, let's expand and combine like terms:

13p - 3p(1 - 2m) - m(2m - 5p) - m²

Expanding the expressions inside parentheses:

13p - 3p + 6mp - 2m² + 5mp - m²

Combining like terms:

10p + 11mp - 3m²

Rearranging the terms:

-3m² + 11mp + 10p

Therefore, the equivalent expression is:

-3m² + 11mp + 10p

Hence the correct option is 2.
