A deposit of $2,000 is made in a trust fund that pays 5.5% interest, compounded continuously. It is specified that the balance will be given to the college from which the donor graduated after the money has earned interest for 30 years. How much will the college receive?

5 + x = 3(x - 7) + 6

Answers

Answer:

x=10

Step-by-step explanation:

x+ 5= 3x - 21 +6

x+5 = 3x - 15

20= 2x

X=10
The reason for this is you distribute the 3 giving you 5+x=3x-21+6.
Then add the 6 to make 5+x=3x-15
Add 15 on both sides to make 20+x=3x
Subtract x on both sides to be 20=2x
Divide both sides by 2 to make 10=x

In a shop, the cost of 4 shirts, 4 pairs of trousers and 2 hats are $560. The cost of 9 shirts, 9 pairs of trousers and 6 hats is $1,290. What is the total cost of 1 shirt, 1 pair of trousers and 1 hat?

Answers

Answer: Given:

4 shirts, 4 pairs of trousers , and 2 hats is $560

9 shirts, 9 pairs of trousers , and 6 hats is $1,290

1) Let x be the price of 1 shirt

Let y be the price of 1 pair of trousers

Let z be the price of 1 hat

2) 4x + 4y + 2z = 560

3) 9x + 9y + 6z = 1,290

4) (9x + 9y + 6z) / 3 = 1,290 / 3

3x + 3y + 2z = 430

5)

4x + 4y + 2z = 560

- (3x + 3y + 2z = 430)

x + y = 130

6) 3(x+y) + 2z = 430

3(130) + 2z = 430

390 + 2z = 430

2z = 430 - 390

2z = 40

z = 40/2

z = 20

7) x = price of 1 shirt; y = price of 1 pair of trousers ; z = price of 1hat

x + y = 130 ; z = 20

130 + 20 = 150

The price of 1 shirt, 1 pair of trousers, and 1 hat is $150.

So this is not impossible!

What is the area of "triangle " XYZ to the nearest tenth of a square inch? Use special right triangles to help find the height. Show your work.

Answers

Answer:

That is a 30 60 90 triangle.

In such a triangle the "middle" size = short side * sq root (3)

height = 5 * sq root (3) =  8.6602540378

Area = (1/2) * 5 * 8.6602540378

Area = 2.5 * 8.6602540378

Step-by-step explanation:

4 Inches on short side, this means that the long side is 8 inches because the short side is always 1/2 the length of the long side, The medium side length is 4√3. So you need to take the short side and medium side and multiply them by 1/2, look below for how to do it.
