To find the distance an object has traveled, you use the formula D=RT; where D=distance, R=rate and T=time.
What was the rate a person drove if they traveled 313.5 miles in 4 hours?
Answer:
Step-by-step explanation:
Answer:
78.375 miles per hour = R
Step-by-step explanation:
D= RT
The miles are 313.5 which is D and the time is 4 hours
313.5 = R * 4
Divide each side by 4
78.375 miles per hour = R

Now add the populations in scientific notation.
Rewrite each estimate so they all have the same power of 10.
Dogs: 69,900,000
Cats: 36,100,000
Birds: 8,300,000
Answer:
question 1 part a =
estimated number of dogs
=6.99 × 107
= 6.99 • 10,000,000
= 69,900,000
estimated number of cats
= 3.61 × 107
= 3.61 • 10,000,000
=36,100,000
estimated number of birds
= 8.3 × 106
= 8.3 • 1,000,000
= 8,300,000
part b = total population of pet dogs, cats, and birds
= 69,900,000 + 36,100,000 + 8,300,000
= 114,300,000
question 2 part a =
The estimated number of dogs is 6.99 x 10^7 .
The estimated number of cats is 3.61 x 10^7.
The estimated number of birds is 8.3 x 10^6.
The power of 10 in 8.3 x 10^6 is 6, which is less than the power of 10 in the other two numbers. To make the calculation simpler, convert this number so the exponents are all the same.
Multiply and divide 8.3 x 10^6 by 10 to increase its exponent by 1:
8.3 x 10^6 = 10/10 x 8.3 x 10^6
= 8.3/10 x 10^6 x 10
= 0.83 x 10^7
part b =
total number of pet dogs, cats, and birds
=
6.99 × 107 + 3.61 × 107 + 0.87 × 107
=
(6.99 + 3.61 + 0.83) • 107
=
11.43 • 107
part c =
No. The sum from part B is not in scientific notation.
The total number of pet dogs, cats, and birds is 11,43 x 10^7. To express the number in scientific notation, the decimal point must be moved one digit to the left. To do that, divide and multiply the number by 10:
10/10 x 11.43 x 10^7 = 11.43/10 x 10^7 x 10
= 1.143 x 10^8
Written in scientific notation, the total number of pet dogs, cats, and birds is 1.143 x 10^8.
question c = They are the same. If you convert the number in standard form from question 1 to scientific notation, it is the same as the number in scientific notation found in question 2.

Cats: 3.61 x [tex]10^8[/tex]
Birds:0.083 x [tex]10^8[/tex]
What is Scientific Notation?Scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Also, the numbers in the millions place after the decimal required to be represented in a simpler format. As a result, representing a few integers in their expanded form is challenging. As a result, we employ scientific notation.
Given:
We have to change the number in Scientific Notation in which only one significant number will be before the decimal and remaindering raise to power of 10.
First, Dogs: 69,900,000 whose Scientific Notation is
= 6.99 x [tex]10^8[/tex]
Second, Cats: 36,100,000 whose Scientific Notation is
= 3.61 x [tex]10^8[/tex]
Third, Birds: 8,300,000 whose Scientific Notation is
= 8.3 x [tex]10^6[/tex]
= 0.083 x [tex]10^8[/tex]

Every five years in February, the population of a certain town is recorded. In 1995, the town had a population of 6,500 people. From 1995 to 2000, the population increased by 8%. From 2000 to 2005, the population decreased by 5%. What was the percent of change in the town's population from 1995 to 2005?
Answer:
The answer is 3%
Step-by-step explanation:
From 1995-2000, it went up 8%. From 2000-2005, it went down 5%. That means, to find the amount of change, we have to subtract 8 and 5, getting 3%. Hope this helped!

Hello!
A function will be increasing if the y values are increasing (since this is a function, this will pass the vertical line test, meaning that it is increasing if the y values are increasing).
On interval 1, the function is not increasing since the y value stays constant.
On interval 2, the function is increasing because the y values are increasing.
On interval 3, the function decreases because the y values are decreasing.
On interval 4, the function increases again.
On interval 5, the function stays the same because of its constant y value.
To reiterate, on intervals 2 and 4, the function is increasing.
