Answer:

Angle b is 50 degrees

Step-by-step explanation:

The two angles add to 90 degrees because it is a right angle. The two angles are complementary.

a+b = 90

We know angle a is 40 degrees

40 +b = 90

Subtract 40 from each side

40-40 +b = 90-40

b = 50

A multiple must be greater than or equal to the largest starting number. True or False

podryga [215]

I'll use multiples of 2 and 4 as an example:

Multiples of 2: 2, 4, 6, 8...

Multiples of 4: 4, 8, 12, 16...

The least common multiple in this case is 4. The LCM is always ≥ the largest starting number, which is 4 for this example. Therefore, the statement is true.

Hope this helps! :)

I need help finding the answer to this:

anygoal [31]

Answer:

He will earn $6 in interest in 9 months.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

$T = E + P$

Initial deposit of $400.

This means that $P = 400$

2% annual interest

This means that $I = 0.02$

How much interest will he earn in 9 months?

An year has 12 months, this means that $t = \frac{9}{12} = \frac{3}{4} = 0.75$

This is E. So

$E = P*I*t = 400*0.02*0.75 = 6$

He will earn $6 in interest in 9 months.
