The speed of a cyclist rode 3.75 miles in 0.3 hours is 0.36 hours.
Given that, a cyclist rode 3.75 miles in 0.3 hours.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
A) We know that, speed =Distance/Time
Now, speed =3.75/0.3
= 12.5 miles per hour
B) Here, distance =4.5 miles and rate =12.5 miles per hour
Now, 12.5 =4.5/Time
⇒ Time =4.5/12.5
⇒ Time =0.36 hour
Therefore, the speed of a cyclist rode 3.75 miles in 0.3 hours is 0.36 hours.

The population last year was 2,639,000,000. This year the population is 3,999,635,444. Which is the best estimate of the total population of last year and this year?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The population has increased by 51.56% from last year to this year.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of population last year = 2,639,000,000
Number of population this year = 3,999,635,444
The best estimate of the total population of last year and this year.
= [ (3,999,635,444 - 2,639,000,000) / 2,639,000,000 ] x 100
= ( 1360635444 / 2,639,000,000 ) x 100
= 51.56 %

Explain.

a. The given sequence is not an arithmetic sequence.
b. The distance a falling body covered in t = n seconds of movement is 5n²meters.
What is the distance?
Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage.
Here, we have
a. A sequence can be said arithmetic sequence if the difference between any two consecutive terms remains the same.
In this case, the difference between 20 and 5 is 15, and the difference between 45 and 20 is 25, this shows that the difference between two consecutive terms is not the same.
Hence, it can be said that the given sequence is not an arithmetic sequence.
b. To evaluate the distance covered by the body in “n” seconds, Substitute t=n in d(t) then d(n) will represent the distance covered by the body in “n” seconds
d(n)=1/2 g(n)²
d(n) = 1/2(10)(n)²
d(n) = 5n²meters
Hence, the distance a falling body covered in t = n seconds of movement is 5n²meters.

You'll apply properties of multiplication in the following steps to find the total cost of the fabric.
1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings. (2 points)
2. Multiply the amount of fabric by the price per yard to find an expression for the total cost.(2 points)
3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with. (3 points)
4. Simplify your expression to find the total cost. Show your work. (3 points)
1) An expression for the amount of fabric needed to make 13 pairs of wings is; 3/4 * $8 = $6 each
2) An expression of the total cost is; 3/4 * $8 * 13 = $78
3) The way we will use associative and commutative properties is to start by treating 1 yard of fabric like the fraction 4/4.
4) Simplifying equals $78
How to solve algebra word problems?We are told that each pair of wings is made with 3/4 yard of fabric. Since the fabric costs $8 per yard. Thus;
1) 3/4 * $8 will give us the cost of the amount required for 3/4 yard of fabric. 3/4 * $8 = $6 each
2) Now, we are told that Mr. Townsend needs to make 13 pairs of butterfly wings and as such;
Amount needed to make 13 pairs is expressed as; 3/4 * $8 * 13 = $78
3) Treat 1 yard of fabric like the fraction 4/4.
Now, if this 1 fabric is equal to $8, then it means that 3/4 of the fabric will be $6. That is for one pair of butterfly wings, there's 13 of those so multiply $6 by 13.
This pattern is easier because we know how much 1 fabric costs, but we don't know what 3/4 of it does, so we treat 1 yard of fabric as the fraction 4/4.
