How you would write an expression that shows the cost to rent the bicycle for d days.

1 answer:

4 0

C= total cost
d= number of days
r= rental cost

C= r * d
C= rd

Example:
If it cost $10 per day and you rented for 5 days, the total cost would be:
C= ($10)(5)
C= $50

Hope this helps! :)

In 2004, Kenenisa Bekele of Ethiopia ran 5,000 meters (5 kilometers) in 12 minutes, 37.35 seconds. What is this distance to the

malfutka [58]

Answer:

Distance=3.1 miles

Step-by-step explanation:

Step 1: Determine how many meters make a mile

The conversion rate expression is;

1 mile=1.60934 kilometers

Step 2: Convert 5 km to miles

Using the expression below;

Distance in miles=distance in kilometers/1.60934

where;

distance in kilometers=5 km

replacing;

Distance in miles=5/1.60934

Distance in miles=3.10686 miles

Step 3: Round off to nearest tenth of a mile

Nearest tenth of a mile=1/10=0.1 , the same as rounding of to the nearest 1 decimal place

Distance 3.10686 miles rounded off to 1 decimal place=3.1 miles

Distance=3.1 miles

Olive buys indie music online. Each song costs $2 plus a $5 fee for using the artist's site. She has no more than $40 to spend.

mina [271]

First, set a variable.

Let x = the number of songs bought.

Each song costs 2 dollars. So, we have our first term: 2x.
And there is a fee of 5 dollars for using the website.

2x + 5

And she can't spend any more than 40 dollars. Which means she can spend 40 and under.

So, 2x + 5 ≤ 40 is the answer.

On a test, Leo is asked to completely factor the polynomial 3x3 – 3x + 5x2 – 5. He uses double grouping to get (x2 – 1)(3x + 5).

Step2247 [10]

Answer:

Leo does not factored the polynomial completely.

3x^3-3x+5x^2-5=(x+1)(x-1)(3x+5)

Step-by-step explanation:

Given: On a test, Leo is asked to completely factor the polynomial

3x^3-3x+5x^2-5.

also, he uses double grouping to get (x^2- 1)(3x+5)

We have to explain whether he factored the polynomial completely or not.

Consider the given polynomial 3x^3-3x+5x^2-5.

after double grouping he get (x^2- 1)(3x+5)

Also, we can simplify further ,

Using algebraic identity a^2-b^2=(a+b)(a-b)

We get,

(x^2- 1)=(x+1)(x-1)

We get, (x^2- 1)(3x+5)=(x+1)(x-1)(3x+5)

Thus, 3x^3-3x+5x^2-5=(x+1)(x-1)(3x+5)

Thus, He does not factored the polynomial completely.

There are two spinners. Each spinner has 10 equal sectors labeled with the numbers 1 through 10.

gtnhenbr [62]

There are 4 prime numbers from 1 to 10: 2, 3, 5, and 7. This means that there are 4 ways to choose the first outcome. There are 5 composite numbers from 1 to 10: 4, 6, 8, 9, and 10 (1 is just 1). So, you just multiply the two numbers together because each depends on each: 4 * 5 = 20 outcomes.
