I think you have to solve like each section like (5x3+3)2 first solve that and then solve the middle one and then the last one and I think they all have to be equal to each other , and if they aren’t then her anwser isn’t correct

Suppose LMN=PQR Which congruency statements are true

zysi [14]

A, D, E and F are all true statements.

When looking for congruence in these type of problems, you have to look for the order of the letters in the original listing. Since they are listed LMN and PQR, this means we have to focus on the placement of those letters. Since L is the first listed in the sequence, it is congruent with P, which is also listed first. M is congruent with Q since they are both in the middle, and N and R are congruent since they are both at the end.

Now to find true statements, you need to make sure everything matches up in the statement.

Let's take A for instance. It states that MN = QR. Now we know M is in the middle and N is at the end. Since Q is in the middle and R is at the end, they match and are therefore true.

Answer:

Option A

Step-by-step explanation:

A'B' is 1/2 times the AB as the scale factor is 1/2.

Find the length of AB using distance formula.

AB = $\sqrt{(4 - 2)^2 + (4-0)^2} = \sqrt{20} = 2\sqrt{5}$

And find A'B':

A'B' = 1/2*2 $\sqrt{5} = \sqrt{5}$

Correct choice is A

1400 dollars is placed in an account with an annual interest rate of 5.5%. to the nearest year, how long will it take for the ac

olga_2 [115]

It will take 19 years and 6 months for the account value to reach 2900 dollars

Step-by-step explanation:

Given

Principal amount = 1400 dollars

Rate = 5.5 %

Final value = A = 2900

We have to find t

So,

The formula for simple interest is:

$A = P(1+rt)$

Putting values

$2900 = 1400(1+0.055.t)\\\frac{2900}[1400} = 1+0.055t\\2.071 = 1+0.055t\\2.071-1=0.055t\\1.071 =0.055t$

Dividing both sides by 0.055

$\frac{0.055t}{0.055} = \frac{1.071}{0.055}\\t = 19.47\ years$

Rounding off to nearest tenth

19.5 years

Hence,

It will take 19 years and 6 months for the account value to reach 2900 dollars
