____________________________________________________

Answer:

Your answer would be a 9.5% increase.

____________________________________________________

Step-by-step explanation:

In order to find the answer to your question, we would need to get the amount it's changing by, divide it by it's original, and multiply it by 100.

Your equation should look like this:

Change/Original * 100

Important information in the question:

105 pounds

115 pounds (increase in amount of food that bear eats)

With the information above,we can plug those numbers into our equation.

Since we need to find the change, we would subtract 115 and 105 to get 10. 10 is our change in this scenario.

Our original started at 105, so that'll be our original in our equation.

When you plug in the information, your equation should look like this:

10/105*100

Now you solve:

10/105*100\\\\0.0952 * 100\\\\=9.523

We have to round to the nearest tenth, and the tenth place is the number right after the decimal place.

Since 2 is not a big enough number to round the 5, we would keep the number as 5. Therefore, your answer would be 9.5

Your FINAL answer would be 9.5%

A school dance committee has 14 volunteers. Each dance requires 3 volunteers at the door, 5 volunteers on the floor, and 6 float
siniylev [52]

There are 91 such ways in whih the volunteers can be assigned if two of them cannot be assigned from 14 volunteers.

Given that a school dance committee has 14 volunteers and each dance requires 3 volunteers at the door, 5 volunteers on the floor and 6 on floaters.

We are required to find the number of ways in which the volunteers can be assigned.

Combinations means finding the ways in which the things can be choosed to make a new thing or to do something else.

nC_{r}=n!/r!(n-r)!

Number of ways in which the volunteers can be assigned is equal to the following:

Since 2 have not been assigned so left over volunteers are 14-2=12 volunteers.

Number of ways =14C_{12}

=14!/12!(14-12)!

=14!/12!*2!

=14*13/2*1

=91 ways

Hence there are 91 such ways in whih the volunteers can be assigned if two of them cannot be assigned.

PLEASE HELP ME ASAP. I REALLY NEED THIS DONE
Juli2301 [7.4K]

Answer:

x = 65

Step-by-step explanation:

using the Altitude- on- Hypotenuse theorem

(leg of big Δ )² = (part of hypotenuse below it ) × (whole hypotenuse)

x² = 25 × 169 = 4225 ( take square root of both sides )

x = \sqrt{4225} = 65
