Answer:
The sum of coefficients = 9
Step-by-step explanation:
The given expression is,
3x⁴ + 5x² + x
There are three terms in the given expression. All the terms contains variable x.
<u>To find the coefficients of each terms
</u>
term coefficients
3x⁴ 3
5x² 5
x 1
<u>To find the sum of coefficients
</u>
sum = 3 + 5 + 1 = 9
Therefore the sum of coefficients = 9
First, let x be the number of hours it will take for Hector to finish the same job alone. This means that every hour, Hector can do 1/x of the job. The amount of work done by Shawn and Hector in 6 hours should be equal to 1 complete work. This can be expressed as,
(1/9 + 1/x)(6) = 1
The value of x is 18. Thus, Hector can to 1/18 of the job in one hour.
350 dollars for the kayak + 1.50 for the fee + the 10.23 interest for the three months = 361.73
Answer:
The orthocenter is the point where all three altitudes of the triangle intersect. An altitude is a line which passes through a vertex of the triangle and is perpendicular to the opposite side.
Answer:
417 is the number of adults that would erase their personal information online if they could, they are the 61%. The complete number is 417,85, but we have to adjust the answer for people.
Step-by-step explanation:
To find the answer we need to do a Rule of Three. The Rule of Three is a Mathematical Rule that will help us to solve problems based on proportions.
1. I know that a 685 adults were surveyed, so this is the 100%. 61% say they would erase all of their personal information online if they could, and we don't know the numbre of people in here.
2. So 685 adults _____ 100%
X adults _____ 61%
Here we have to put the same elements in the same columns. Students with studients and percentage with percentage.
3. Now I have to cross these details. I have to multiple 61*685. So:
61*685= 41785
4. Then divide that result by 100.
41785/100= 417,85
5. So 417 is the total number of adults that would .
