a man is 3 times as old as his son. the sum of their ages is 48 years, how old is the son?

Answers

Answer 1

Let the sons age = x

The dads age would be 3x ( 3 times the sons age)

X + 3x = 48

Simplify:

4x = 48

Divide both sides by 4

X = 12

The sons age is 12

What is linear inequality?

Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.

Unlike a linear equation it can have a range of values inside an interval.

The given statement can be written in terms of inequality as,

2/3x - 6 ≥ -24

=> 2/3x  ≥ -24 + 6

=> 2/3x  ≥ -18

=> x ≥ -27

Hence, the inequality expression for the given problem can be written as x ≥ -27.

If x2 + y2 = 14 and xy = 5, find the value of (1/2 x + 1/2 y)2.

Answers

Answer:

(½x+½y)²=6

Step-by-step explanation:

x^2 + y^2 = 14, xy=5

(A+B)^2=A^2 +2AB+B^2... (*)

(1/2x+1/2y)^2 =(*)

(1/2x)^2 +2(1/2x)(1/2y)+(1/2y)^2 =

1/4x^2 +1/2xy+1/4y^2=

1/4(x^2 +y^2) +1/2(xy)=

1/4*14+1/2*5=

14/4+5/2=

14/4+10/4=

24/4=6

let me know if I'm wrong.

( 1/2x +1/2y)²

= { ( x + y )/ 2xy }²

= ( x² + 2xy + y² )/4(xy)² —(1)

As we know that x² + y² = 14 — (2)

and xy = 5 —(3)

So, substitute the value of equation 2 and 3 in equation 1,

= ( x² + 2xy + y²)/4(xy)²

=( 14 + 2*5)/(4*5²)

= 24/(4*25)

= 6/25.

Amy contributes $50 per month into the Lincoln National Bond Fund that earns 7.26% annual interest.What is the value of Amy’s investment after 25 years?

Answers

Answer:

Inc Interest : $16,089

Step-by-step explanation:

1. Let's turn $50 a month into a year, so 50 * 12 = $600

2. Including the annual interest, which is $43.56 out of the $600

3. Add them together, which will be 43.56 + 600 = 643.56

4. Multiply it by 25 to get the full 25 years and you're done!

The value of Amy's investment after 25 years will be $140.75.

What is simple interest?

Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest. The straightforward crediting of cash flows related to an investment or deposit is referred to as "simple" interest.

Given that, Amy contributes $50 per month to the Lincoln National Bond Fund which earns 7.26% annual interest.

The investment after 25 years will be calculated as,

SI = ( P x R x T)/100

SI = ( 50 x 7.26 x 25 ) / 100

SI = $90.75

The total investment will be calculated as,

A = $90.75 = $50

A = $140.75

Therefore, the value of Amy's investment after 25 years will be $140.75.
