Factor 200t+8t^3-80t^2
valina [46]

Answer:

8t(t - 5)^2

Step-by-step explanation:

I would immediately rearrange these terms in descending order by powers of t:

8t^3 - 80t^2 + 200t

Then I'd factor out 8t:

8t(t^2 - 10 t + 25).

Finally, I'd factor the quadratic t^2 - 10 t + 25:

(t - 5)^2

and so 200t+8t^3-80t^2 in factored form is 8t(t - 5)^2.

In a standard deck of playing cards, one-fourth of the cards are hearts.
makkiz [27]

Answer:

\sf D) \quad \dfrac{1}{64}

Step-by-step explanation:

\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}

Probability of drawing a heart from one deck:

\sf \implies P(heart)=\dfrac{1}{4}

Therefore, probability of drawing a heart from each of 3 decks:

\sf \implies P(heart)\:and\:P(heart)\:and\:P(heart)=\dfrac{1}{4} \times \dfrac{1}{4} \times \dfrac{1}{4}=\dfrac{1}{64}

A nut mixture of peanuts and pecans at a small fair is $1.00 per pound of peanuts and $4.25 per pound of pecans. Over the entire
34kurt
Hello!

You can solve this algebraically

p + n = 115

p + 4.25n = 358.75

Subtract the two equations to eliminate p

-3.25n = -243.75

Divide both sides by -3.25

n = 75

Put n into the first equation

p + 75 = 115

Subtract 75 from both sides

p = 40

The answers are,

40 pounds of peanuts were sold
75 pounds of pecans were sold

Hope this helps!

Jenny and Mark are reading the same book for their English class.
Harrizon [31]

Answer:

10 days

Step-by-step explanation:

Jenny has read 50 pages and will read 15 each day.

The equation would be: 15x+50

Mark will read 20 pages daily.

The equation would be: 20x

In both equations x represents days.

You set both equal to each other because you want to know when they read the same amount of pages.

15x+50=20x

...you subtract 15x from both sides

50=5x

...and divide by five to get: 10 days
