If you invest $2,000 today in a bank that gives you a 4 percent annual interest rate, which of these items can you buy in seven years?

Answers

Answer 1
Answer: Just the Mountain bike, cause 4% of $2000 is, $80. and $80 for each year for 7 years make $560. now after 7 years your bank account has $2560. Therefore, you can buy a mountain bike, and have $60 left over, if there is no tax included. But if there is tax, your going to be still short by $115.(calculated according to florida's tax, that is 7%.) Anyways if the tax is over 2% you cant get that bike.
Answer 2
Answer: All of them 

put this in a calculator: 2000*20%*7 then take away the prices or bills and thats how much money is left after the shopping spree

C) (3, 2/9)
D) no solution

Answers

If you would like to know the solution to the system of equations, you can calculate this using the following steps:

6x – 9y = 16
2x – 3y = 7     /*(-3) ...  -6x + 9y = - 21
___________
6x – 9y - 6x + 9y = 16 - 21
0 = - 5

The correct result would be D) no solution.

What is the greatest common factor of the terms in the expression 36a+54ab-27b?

Answers

The greatest common factor of the terms in the expression 36a+54ab-27bis 9 or 9(4a + 6ab + 3b)

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

= 36a+54ab-27b

The factors of 27 are: 1, 3, 9, 27

The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36

The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54

The greatest common factor of 36, 54, and 27 is 9

= 9(4a + 6ab + 3b)

Thus, the greatest common factor of the terms in the expression 36a+54ab-27bis 9 or 9(4a + 6ab + 3b)

Answer:

The answer is 9

Step-by-step explanation:

Two sides of an acute triangle measure 5 inches and 8 inches. The longest side is unknown. What is the greatest possible whole-number length of the unknown side?

Answers

Answer:

Hence, the greatest possible whole-number length of the unknown side is:

9 inches

Step-by-step explanation:

A corollary to the Pythagorean Theorem states that:

If c is the longest side of a acute triangle, a and b are other two sides of a acute triangle then the condition that relates these three sides are given as:

c^2<a^2+b^2

Here we have:

Let a=5 inches.

b=8 inches.

Then,

c^2<5^2+8^2\n\nc^2<25+64\n\nc^2<89\n\nc<9.434

Hence, to the greatest whole possible whole number length of the unknown side is:

9 inches.

Answer:

the answer is 9

Step-by-step explanation:

A fisherman can row upstream at 4mph and downstream at 6mph. He started rowing upstream until he got tired and then started downstream to his start point. How far did the fisherman row if the trip took 3 hours?

Answers

Answer:

Fisherman traveled 14.4 miles.

Step-by-step explanation:

A fisherman's downstream speed = 6 mph

and upstream speed = 4 mph

Let the fisherman traveled x miles he travels upstream.

Time spent in travelling x miles = (x)/(4) hours [Since time = \frac{\text{distance}}{\text{speed}}]

Similarly when fisherman covers x miles down stream

Time spent in x miles = (x)/(6) hours

Now total time in going upstream and downstream is 3 hours then

(x)/(4)+(x)/(6)=3

x((3+2)/(12))=3

((5x)/(12))=3

5x = 12×3

5x = 36

x = (36)/(5)=7.2 miles.

Since fisherman has traveled 2x distance so the answer will be 14.4 miles

Therefore, fisherman traveled 14.4 miles.

total time = upstream time + downstream time
he rowed the same distance both ways.
upstream time = D/4
downstream time = D/6
total time = D/4 + D/6 = 3D/12 + 2D/12 = 5D/12 = 3 hours
D = 3*12/5 = 36/5 or 7.2 miles
where D is the one-way distance. The total distance he rowed is 2*D = 72/5 or 14.4 miles

270 is 75% of what number?

Answers

First, you have to divide 270 by 3, so you get 25%. This comes out to be 90. So, 90 is 25%. Now, multiply this by four to get 100%. This comes out to be 360. So, 270 is 75% of 360, which answers the question '270 is 75% of what number?'
