Mathematics
1 answer:
sammy [17]3 years ago

Answer:

a = 12cm

Third option

Step-by-step explanation:

Use the pythagorean theorem because this is a right triangle and you are looking for a missing side.

The formula is:

a² + b² = c², where "a" and "b" are sides, but "c" is the hypotenuse (longest side).

We know the hypotenuse and one other side.

Substitute side "b" and "c".

a² + 5² = 13²

a² + 25 = 169   Isolate "a"

a² = 169 - 25    Subtract 25 from both sides

a² = 144         Find the square root of both sides

a = √144

a = 12

The mssing side, "a", is 12 cm long.

Answer:

His money earned $36 after 3 months

Step-by-step explanation:

* Lets revise the rules of simple interest

- Simple Interest Equation (Principal + Interest)

 A = P(1 + rt)

- Where:

• A = Total amount (principal + interest)  future amount

• P = Principal Amount

• I = Interest Amount

• r = Rate of Interest per year in decimal; r = R/100

• t = Time Period involved  

* To calculate the interest I use the formula

  I = P × r × t

* Lets solve the problem

- The rate is annual

- The interest calculated after 3 months

∴ I = P × R/100 × t/12

∵ P = $3600.00

∵ R = 4%

∵ t = 3 month

∴ I = 3600.00 × 4/100 × 3/12 = $36

* His money earned $36 after 3 months

Answer:

Step 2 contains error in the given problem.

Step-by-step explanation:

Given expression is:

\frac{1}{2}x-3=\frac{1}{3}x+6

Step 1: identifying the LCM.

The LCM identified is 6.

This step is correct.

In the next step, we multiply the LCM with each term of the equation.

Step 2:

\frac{6}{1}(\frac{1}{2}x) -3 =\frac{6}{1}(\frac{1}{3}x)+6

However,

In the given solution, the LCM is not multiplied with each term.

Hence,

Step 2 contains error in the given problem.
