Answer:
5
Step-by-step explanation:
6x^2 + 7x^3 + 8x^5 +9
Write in order from highest power to lowest power
8x^5 + 7x^3 + 6x^2 +9
The highest power ( largest exponent) is 5
The degree of the polynomial is 5
Answer:

Given:

To find:

Step-by-step explanation:

You can use lattice multiplication or long multiplication. for examples and/or visuals message me.
We can convert 20km to 20,000m. Then, we can subtract 800m (walking distance) from 20,000m which would result in 19,200m. Then we can put 19,200m and 20,000m as a fraction (19200/20000). Before we can multiply it by 100 to make it in the percentage form, we can get rid of 2 zeroes for both number making it 192/200 and then further simplifying it to 24/25 by dividing both numbers by 8. Finally to get the percentage we can multiply 24 and 100 (2400) and then divide the result (2400) by 25. The final answer is 2400/25=96 meaning he cycled 96% of the journey and walked 4% of the journey (100-96=4).
Jasmine can run in one hour is 7.25 miles.
<h3>What is the formula of unitary method?</h3>
The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
Given that,
Jasmine can run 4
miles in
of an hour.
of an hour = 4
miles
=
miles
By using unitary method we will find the value of an hour.
1 hour = 
=
× 
= 
1 hour = 7.25 miles
Hence, Jasmine can run in one hour is 7.25 miles.
