When Melissa was born, her parents put $28,000 into a college fund account that earned 11.5% simple interest. Find the total amount in the account after 240 months.

Answers

9514 1404 393

Answer:

$92,400

Step-by-step explanation:

The amount in the account after t years is ...

A = P(1+rt)

where P is the principal invested, r is the annual interest rate, and t is the number of years.

Here, the number of years is (240 months)/(12 months/year) = 20 years, so the formula tells you the amount is ...

A = $28,000(1+0.115*20) = $28000(3.3) = $92400

The total amount in the account after 240 months is $92,400.

How many soap cakes can be placed in a box of size 56 cm x 0.4 m 0.26 m, if the size
of a soap cake is 7 cm x 5 cm x 2.5 cm?

Answers

Answer:

length of box = 56cm

breadth = 0.4m = 40cm

height = o.25m = 25cm

Volume of Box = Volume of soap × n

n = number of soaps.

LBH = lbh × n

56 × 40 × 25 = 7 × 5 × 2.5 × n

n = 56×40×25/35×2.5

n = 56000/87.5

n = 640

so, 640 soaps can be placed in the box.

Joey has two pieces of wood. One is 120 inches and the other one is 210 inches long. He wants to cut both the pieces into smaller parts so that all these parts are of the same length.
i) If he wants the smallest pieces to be as long as possible without having any leftover, how long should each piece be?
Ans:
ii) How many smaller pieces of wood will he have in total?
Ans:

Answers

Answer:

A. 30 inches

B. 11 pieces

Step-by-step explanation:

Piece 1 = 120 inches

Piece 2 = 210 inches

1. He wants the smallest pieces to be as long as possible without having any leftover, how long should each piece be?

Find the highest common factor of 120 and 210

120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.

210: 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210.

The highest common factor of 120 and 210 = 30

Therefore, the smallest and longest pieces should be cut into 30 inches each

B. Total Smaller pieces of wood = piece 1 / 30 + piece 2 / 30

= 120/30 + 210/30

= 4 + 7

= 11 pieces

What is the answer to this: f(x) = -1/3x -6

Answers

Answer:

x=0

x=1

The table already give us a hint, which is a set of values that are telling us what is the value of every function f(x) and g(x) for a given value for 'x' variable.

From the table we know that f(x) decreases when x>0 and goes in the other direction when x<0.

g(x) goes on a different direction, when x>0, it gets bigger, and when x<0, the function decreases.

So the two functions do not have too much space for being equal.

So, you can use the points given in the table to start your test.

f(0)= 0,25 ^ 0=1 since a number raised to 0 is always 0.

g(0)=-0.75 * 0 + 1 = 1

f(1)=0.25^1=0.25 since a number raised to 1 is always equals to itself

g(1)=-0.75*1+1=0.25

So f(x)=g(x), when x=1 and when x=0
