Answer 1

Answer:

According to given question, The simplified polynomial in standard form is: $-t^4 + 4t^3 - 7t^2 - 1$

To add the two polynomials and simplify, we'll combine like terms:

$(-t^4 - 5t^3 - 10t^2) + (9t^3 + 3t^2 - 1)$

In mathematics, a polynomial is an algebraic expression consisting of variables (also known as indeterminates) and coefficients, combined using addition, subtraction, and multiplication operations. The variables are raised to non-negative integer powers, and the coefficients are constants that multiply the variables. The term "polynomial" comes from the Latin words "poly" (meaning "many") and "nomial" (meaning "term").

Step 1: Combine the terms with $t^4 and t^3:$

$(-t^4) + (9t^3 - 5t^3) - 10t^2 + 3t^2 - 1$

Step 2: Combine the $t^3$ terms and the $t^2$ terms:

$(-t^4) + (4t^3) - 7t^2 - 1$

So the simplified polynomial in standard form is:

$-t^4 + 4t^3 - 7t^2 - 1$

Answer 2

Answer:

Answer:

$- {t}^(4) + 4 {t}^(3) - 7 {t}^(2) - 1$

Step-by-step explanation:

$( - {t}^(4) - 5 {t}^(3) - 10 {t}^(2) ) + (9 {t}^(3) + 3 {t}^(2) - 1) \n = - {t}^(4) - 5 {t}^(3) - 10 {t}^(2) + 9 {t}^(3) + 3 {t}^(2) - 1 \n = - {t}^(4) + 9 {t}^(3)- 5 {t}^(3) + 3 {t}^(2) - 10{t}^(2) - 1 \n = - {t}^(4) + 4 {t}^(3) - 7 {t}^(2) - 1$

What percent Is 27 percent of 300

Answers

"27 percent" means 0.27

"of" means "times"

"27 percent of 300" means (0.27 x 300) = 81 .

At the beginning, you asked what percent this is.

81 is 8,100 percent .

In order to solve this you need to set up a PROPORTION. Remember that proportions are your friend!

27/100 = x/300

Now just solve for x!

100x = 8100
x = 81

27% of 300 should be 81.

Lamont's buys 9 gallons of ice cream. He has 34 guests coming. If each guest eats 2 1/2 cups, how many pints will he have left?

Answers

We know that 1 gallon is equal to 16 cups.
So 9 gallons is 144 cups.
each guest eats 2.5 cups, and there are 34 guests,
2.5 times 34 = 85, the amount eaten by the guests.
So to figure out whats left, subtract the eaten from the total.
144-85=59
59 is the answer.

Riverside Elementary School is holding a school-wide election to choose a school color. Five eighths of the votes were for blue, five ninths of the remaining votes were for green, and the remaining 48 votes were for red. How many votes were for blue? How many votes for green?

Answers

1) Write out what you know
Blue: 5/8
Green: 5/9 (of 3/8 because it is the remaining parts) so 5/24
Red: 1 - (5/8 + 5/24) = 1/6
2) Find the total amount of people
You know that 1/6 of the population is 48, so the total population is 288 (48×6)
3) Multiply the total population by the fractions to get the number of votes
Blue: 288 × 5/8 = 180 votes
Green: 288 × 5/24 = 60 votes

Check: 180 + 60 + 48 = 288 votes

Answer:

180
