What is factor for 7x^2-21-280

Answers

Answer 1
7x^2 − 21 −280
= 7x^2 + −21 + −280

Then combine like terms:
= 7x^2 + −21 + − 280
= (7x^2) + ( − 21 + − 280)
= 7x^2 + −301

Lila plans to open an account with a deposit of $12,000. She plans to invest the money for 8 years in one of the following accounts:
An account that pays an annual simple interest of 7.5%, or
An account that pays 6% interest compounded annually.
If Lila invests in the account that will earn her more interest over these 8 years, how much interest will she earn?

Answers

9514 1404 393

Answer:

  $7200

Step-by-step explanation:

The amount of simple interest can be found from ...

  I = Prt . . . . . . . where principal P is invested at annual rate r for t years

__

The amount of compound interest can be found from ...

  I = P((1 +r)^t -1) . . . . . same variable definitions

__

The amount of simple interest earned is ...

  I = 12000·0.075·8 = 7200

The amount of compound interest earned is ...

  I = 12000(1.06^8 -1) ≈ 7126.18

In this scenario, the simple interest account earns more interest. If Lila chooses that one, the amount of interest earned is $7200.

Answer:

Step-by-step explanation:

Well, First let us find the amount of numbers in a die greater than 3.

Remember greater than 3 does not include 3.

We have 3 numbers, 4,5,6 that are greater than 3.

The probabilty of getting a rolling a number greater than 3 is 3/6.

The  probability of the coin landing on heads is 1/2.

BUT, the problem is only requiring for you to find the probabilty of rolling a dice greater than 3. (key words)

Which is 3/6 or simplified to 1/2.

Given:

In the given triangle the measure of two angles are 102 degree and 28 degrees and the sides of the triangle are a, 27 cm, c.

To find:

The value of a.

Solution:

Let the given triangle be ABC, such that,

[tex]m\angle B=28^\circ[/tex]

[tex]m\angle C=102^\circ[/tex]

[tex]b=27\ cm[/tex]

Using angle sum property of triangles, we get

[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex]

[tex]m\angle A+28^\circ+102^\circ=180^\circ[/tex]

[tex]m\angle A=180^\circ-28^\circ-102^\circ[/tex]

[tex]m\angle A=50^\circ[/tex]

According to the Law of Sines:

[tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}[/tex]

[tex]\dfrac{\sin 50^\circ }{a}=\dfrac{\sin 28^\circ }{27}[/tex]

[tex]\dfrac{27\times \sin 50^\circ }{\sin 28^\circ}=a[/tex]

[tex]\dfrac{27\times \sin 50^\circ }{\sin 28^\circ}=a[/tex]

[tex]a\approx 44.06[/tex]

Therefore, the value of a is about 44.06 cm.

Answer:

25 pounds cashews15 pounds peanuts

Step-by-step explanation:

Let c represent the number of pounds of cashews in the mix. Then 40-c is the number of pounds of peanuts. The total cost of the mix is ...

  10c +2(40 -c) = 7(40)

  8c +80 = 280 . . . . simplify

  c +10 = 35 . . . . . . . divide by 8

  c = 25 . . . . . . . . . . subtract 10

  40-c = 40-25 = 15 . . . . pounds of peanuts

25 pounds of cashews and 15 pounds of peanuts should be used in the mix.
