Answer:

The interest he will be paid in the first 4 years is $360

Step-by-step explanation:

The rule of the simple interest is I = Prt, where

  • P is the initial deposit
  • r is the rate in decimal
  • t is the time

∵ Bill deposits $3,000 into an account

∴ P = 3000

∵ The account pays simple interest at a rate of 3% per year

∴ r = 3% = 3 ÷ 100 = 0.03

∵ The time is 4 years

∴ t = 4

→ Substitute these values in the rule above

∵ I = 3000(0.03)(4)

∴ I = 360 dollars

∴ The interest he will be paid in the first 4 years is $360

The average yearly salary of a lawyer is ​$26 thousand less than twice that of an architect.​ Combined, an architect and a lawye
Paha777 [63]

The architect earns $47000 yearly and the lawyer earns $68,000 yearly.

<h3>How to solve algebra problems?</h3>

Let x = salary of architect, in thousands

Let 2x - 26 be the salary of lawyer, in thousands

Thus, if their salary combined is $214 thousand, then we have the algebra expression;

2x + 2x - 26 = 214

4x - 26 = 214

4x = 214 - 26

4x = 188

x = 47, in thousands.

The architect earns $47000 yearly

The lawyer earns 2(47000) - 26000 = $68,000 yearly

If the square root of p2 is an integer greater than 1, which of the following must be true? I. p2 has an odd number of positive
Grace [21]

Answer:

Option | and Option || is True

Step-by-step explanation:

Given:

If the square root of p^{2} is an integer greater than 1,

Lets p = 2, 3, 4, 5, 6, 7..........

Solution:

Now we check all option for p^{2}

Option |.

p^{2} has an odd number of positive factors.

Let p=2

The positive factor of 2^{2}=4=1,2,4

Number of factor is 3

Let p=3

The positive factor of 3^{2}=9=1,3,9

Number of factor is 3

So, p^{2} has an odd number of positive factors.

Therefore, 1st option is true.

Option ||.

p^{2} can be expressed as the product of an even number of positive prime factors

Let p=2

The positive factor of 2^{2}=4=1,2,4

4=2\times 2

Let p=3

The positive factor of 3^{2}=9=1,3,9

9=3\times 3

So, it is expressed as the product of an even number of positive prime factors,

Therefore, 2nd option is true.

Option |||.

p has an even number of positive factors

Let p=2

Positive factor of 2=1,2

Number of factor is 2.

Let p=4

Positive factor of 4=1,2,4

Number of factor is 3 that is odd

So, p has also odd number of positive factor.

Therefore, it is false.

Therefore, Option | and Option || is True.

Option ||| is false.
