Answer: 56 years

Step-by-step explanation:

Let Adam's age be $x$ , since the father is 3 times as old as him , then the father will be $3x$ .

Two years ago

Adam = $x - 2$

Father = $3x - 2$

since Adam was 15 years old 2 years ago , this means that

$x-2=15$

add 2 to both sides

$x = 17$

Therefore , Adam is presently 17 years old , then the father will be 3(17) years , which means that the father is presently 51 years old.

In 5 years time , the father will be 51 + 5 years old. That is , the father will be 56 years old in 5 years time

disa [49]

If you sketch the path of the boat, you will form a right triangle towards the port. The distance from the port to the present position is the hypotenuse since it is opposite from the right angle formed by the 12 miles north and 5 miles east movement. Since it is a right triangle, use the Pythagorean Theorem to solve the hypotenuse.

Solution:

h² = o² + a²
h² = 12² + 5²
h² = 144 + 25
h² = 169
√h² = √169
h= 13

The present distance of the boat from the port is 13 miles.

Question 1 of 10 Diana invested $3000 in a savings account for 3 years. She earned $450 in interest over that time period. What

dangina [55]

Hey there!!

The question states that a sum is invested which is $3000 and hence, this would be counted as the principle amount or the principle sum.

The term given is 3 years, which gives us the idea that this interest is being counted or being active for 3 years.

She ( Diana ) earned the sum $450 at the end of three years. This means, the simple interest is $450.

Never get confused with the principle amount, principle sum and interest.

Principle amount = Principle sum + The interest.

Formula given :

I = prt

'p' is denoted as the principle sum, r is the rate and the t is the term or the number of years.

Now, plugging in all the values :

... 450 = 3000×r×3

... 450 = 9000×r

... r = 450 / 9000

... r = 0.05

... r = 5%

As we need the answer in the decimal form, the answer would be 0.05

Hope my answer helps!!
