Answers

Answer:

Total interest = A - P = $2,223.00

Total amount = $10,023.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 9.5%/100 = 0.095 per year.

Solving our equation:

A = 7800(1 + (0.095 × 3)) = 10023

A = $10,023.00

The total amount accrued, principal plus interest, from simple interest on a principal of $7,800.00 at a rate of 9.5% per year for 3 years is $10,023.00.

Answers

Answer:

FE = 10.30

ED = 7.62

FD = 7.28

Step-by-step explanation:

First, use coordinate system to draw a square that each angle of triangle reach the sides of the square, then use Pythagoras theory to find the length of the sides(c^2=a^2+b^2)

FE = root(9^2+5^2) = root(106) = 10.30

ED = root(3^2+7^2) = root(58) = 7.62

FD = root(2^2+7^2) = root(53) = 7.28

The Sum Of Two Numbers Is 18 And Their Difference Is 4

Answers

Answer:

The two numbers are 7 and 11.

[711?  Is this an ad?  ← :)]

Step-by-step explanation:

Let A and B stand for the two numbers.

We are told that:

1)  A+B=18, and

2)  A-B=4

Take the first expression and rearrange to isolate A:

A+B=18

A=18-B

Use this in the second expression:

(18-B)-B=4

-2B = -14

B = 7

From (1) we find A:  

A+B=18

A+7=18

A= 11

If A=11, then B=7 (from A+B=18)

CHECK:

Does A+B=18?

  11 + 7 = 18?  YES

Does A-B=4?

    11 - 7 = 4?  YES

So we have 2/3 s + 5/6 s
In order to simplify this, we need to get a common denominator and we can do this by multiplying 2/3 by 2, which yields 4/6 s.

Now, we add the two together:
4/6(s) + 5/6(s) = 9/6 (s) = 21

Finally, we can divide 21 by 9/6 which yields 126/9. This simplifies to 14.

One person suggests that Paul can make the diameter of the hole 1 inch greater than that of the ball. Another suggests the diameter should be 2inches greater. Which suggestion should Paul choose? Explain Use the excerpt from Benjamin Franklins letter to James Parker to answer the question.Excerpt from a letter by Benjamin Franklin to James Parker, March 20, 1751I have, as you desire, read the Manuscript you sent me; and am of Opinion, with the publick-spirited Author, that securing the Friendship of the Indians is of the greatest Consequence to these Colonies; and that the surest Means of doing it, are, to regulate the Indian Trade, so as to convince them, by Experience, that they may have the best and cheapest Goods, and the fairest Dealing from the English; and to unite the several Governments, so as to form a Strength that the Indians may depend on for Protection, in Case of a Rupture with the French; or apprehend great Danger from, if they should break with us. . . .A voluntary Union entered into by the Colonies themselves, I think, would be preferable to one imposd by Parliament; for it would be perhaps not much more difficult to procure, and more easy to alter and improve, as Circumstances should require, and Experience direct. It would be a very strange Thing, if six Nations of ignorant Savages should be capable of forming a Scheme for such an Union, and be able to execute it in such a Manner, as that it has subsisted Ages, and appears indissoluble; and yet that a like Union should be impracticable for ten or a Dozen English Colonies, to whom it is more necessary, and must be more advantageous; and who cannot be supposed to want an equal Understanding of their Interests.Were there a general Council formd by all the Colonies, and a general Governor appointed by the Crown to preside in that Council, or in some Manner to concur with and confirm their Acts, and take Care of the Execution; every Thing relating to Indian Affairs and the Defence of the Colonies, might be properly put under their Management. Each Colony should be represented by as many Members as it pays Sums of Hundred Pounds into the common Treasury for the common Expence; which Treasury would perhaps be best and most equitably supplyd, by an equal Excise on strong Liquors in all the Colonies, the Produce never to be applyd to the private Use of any Colony, but to the general Service. Perhaps if the Council were to meet successively at the Capitals of the several Colonies, they might thereby become better acquainted with the Circumstances, Interests, Strength or Weakness, &c. of all, and thence be able to judge better of Measures proposd from time to time: At least it might be more satisfactory to the Colonies, if this were proposd as a Part of the Scheme; for a Preference might create Jealousy and Dislike.Analyze the excerpt from Benjamin Franklins letter to explain how competition among European powers led to the French and Indian War and encouraged unity among the colonies.
