Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{40}}}}}$

Step-by-step explanation:

$\sf{50 \: \% \: of \: 80}$

To convert the percent into a fraction , divide it by 190 and remove the % symbol. Then , Simplify the fraction to its lowest term.

⇒ $\sf{ \frac{50}{100} \times 80}$

⇒ $\sf{ \frac{1}{2} \times 80}$

Divide 80 by 2

⇒ $\sf{40}$

Hope I helped!

Skylar is answering the following math problem: The value of an investment decreased by 10%. The original amount of the investme

Alona [7]

Answer:

The given parameters of the investment are;

The rate of decrease of the investment, r = -10%

The original amount of the investment, P = $75.00

Let 'A' represent the final answer (value of the investment) after the decrease in the investment, 'r', is applied, we have;

The algebraic equation that can be used to arrive at the final answer, 'A', is given as follows;

A = P + r·P

Therefore by substituting the given values, we have;

A = $75.00 + (-10/100) × $75.00 = $75.00 - 0.1 × $75.00 = $75.00 - $7.50

A = $75.00 - $7.50 = $67.50

The final amount or answer, A = $67.50

Find the difference when the polynomial -5x^2+3x+8 is subtracted from the polynomial 2x^2+4x+1.

geniusboy [140]

The difference is $7x^{2} + 1x-7$ .

Step-by-step explanation:

Step 1:

The polynomial $-5x^{2}+3x+8$ is subtracted from the polynomial $2x^{2} + 4x +1$ .

If we write this as an equation, we get

$(2x^{2} + 4x +1) -(-5x^{2}+3x+8)$ .

To subtract the polynomials, we group up the terms based on their variables.

In this subtraction, there are two variables i.e. $x^{2}$ and $x$ and there is one constant term.

Step 2:

The subtraction of the $x^{2}$ variables; $2x^{2} -(-5x^{2} ) = 2x^{2} +5x^{2} = 7x^{2}$ .

The subtraction of the $x$ variables; $4x - (3x) = 1x$ .

The subtraction of the constants; $1-(8) = -7$ .

So $(2x^{2} + 4x +1) -(-5x^{2}+3x+8) = 7x^{2} + 1x-7$ .

Jacob's favorite movie is 1 5/6 hours long. He says he has watch the movie 5 and a half times. If that is true. How many hours h

34kurt

$1\frac{5}{6}$ = $\frac{11}{6}$ , and when you multiply it by 5 it turns into $\frac{55}{6}$ , which is $9\frac{1}{6}$

So in conclusion he watched 9 & 10 minutes watching the movie
