Estimate a 15% tip on a taxi ride that cost $23.25

Anettt [7]

So basically, we are looking for the amount of tip that the rider gave the driver if the driver paid a total of 23.25 dollars. So in order to get the tip, we just have to multiply the total cost of the taxi, which is 23.25, to the percentage of the tip which is 15%. So in order to get the final answer, we have to express the formula as this. 23.25 x 0.15. So if we would solve this equation, we will get an answer of 3.4875. So the tip that was given was 3.4875

b. Sixty-five pounds of candy was divided into four different boxes. The second box contained twice the amount of the first box.

Ainat [17]

First box = 14 pounds

Second box = 2x = 28 pounds

Third Box = x+2= 16 pounds

Fourth box = x/2 = 7 pounds

<u>Step-by-step explanation:</u>

Here we have , Sixty-five pounds of candy was divided into four different boxes. The second box contained twice the amount of the first box. The third box contained two more pounds than the first box. The last box contained one-fourth the amount in the second box. We need to find How much candy was in each box. Let's find out:

We have a total of 65 pounds of candy ! Let in first box we have x pounds so , second box contained twice the amount of the first box i.e.

⇒ $2x$

The third box contained two more pounds than the first box i.e.

⇒ $x+2$

The last box contained one-fourth the amount in the second box i.e.

⇒ $(\frac{1}{4})2x = \frac{x}{4}$

Therefore , Sum of pounds of candy are :

⇒ $\frac{x}{2} +x+2+2x+x=65$

⇒ $\frac{x}{2} +4x=63$

⇒ $\frac{9x}{2}=63$

⇒ $x=63(\frac{2}{9} )$

⇒ $x=14$

Therefore , Candy in each box is :

First box = 14 pounds

Second box = 2x = 28 pounds

Third Box = x+2= 16 pounds

Fourth box = x/2 = 7 pounds

What’s (3b-5c)(2x+5y) squared

lukranit [14]

Answer: In your problem, you said that they are squared. However, it is not written as squared. We just have to multiply them.

We can use the FOIL method.

(3b - 5c)(3x + 5y)

6bx + 15by - 10cx - 25cy

There are no like terms, so that expression is our final answer.

The students at a community center are participating in a bike riding fundraiser at a local park. A local company is donating $1

Oksi-84 [34.3K]

Answer:

This can not be properly answered, because we do not have the length of each trail.

The first step here will be find the length, in miles, for each of the four trails.

As students choose all four trails, the number of miles that each student will bike is equal to the addition of the lenght of the four trails.

Suppose this number is N.

So each student bike N miles, and the company donates $1.75 per mile. Then the amount of money that a single student is N times $1.75, or N*$1.75
