Correct Answer: Option A

Principal Amount = P = $23,400
Interest rate = r = 3% = 0.03
Time = t = 10
Number of compounding periods in a year = n = 2
Compounded amount = A = ?

Formula for compound interest is:

$A = P(1+ \frac{r}{n} )^{t*n}$

Using the values, we get:

$A=23400(1+ \frac{0.03}{2})^{2*10}=31516.41$

Option A is the closest one, so its the correct answer

Who can help me ! .... thanks

Tasya [4]

Given that there is no any option to choose I am going to help you according to the concepts of Congruent Triangles. Two triangles are congruent if and only if:

1. They have:exactly the same three sides
2. exactly the same three angles.

There are five ways to find if two triangles are congruent but in this problem we will use only two.

First Answer:

ASA criterion: Angle, side, angle. This means that we have two triangles where we know two angles and the included side are equal.

So:

If ∠BAC = ∠DEF and $\overline{AC}=\overline{DE}$

Then ΔABC and ΔEFD are congruent by ASA criterion.

Second answer:

SAS criterion: Side, angle, side. This means that we have two triangles where we know two sides and the included angle are equal.

$If \ \overline{AC}=\overline{DE} \ and \ \overline{BC}=\overline{DF}$

Then ΔABC and ΔEFD are congruent by SAS criterion.

Help me i beg u plzzzz

Ainat [17]

We can say at month 0 she was 43 inches tall.

And at month 18 she was 52 inches tall.

We can say that x is the number of months and y is her height.

Rise/run
y2-y1/x2-x1
52-43/18-0
9/18
1/2

So the slope is 1/2 (which is what you are looking for.) and if you were to write an equation it would be y=1/2x+43

Brainliest my answer if it helps you out?

Unit rate feet per second 180 miles over 2 hours

Tatiana [17]

So that is equal to 180 miles per 2 hours which is 90 miles per hour if each hour has the same m/hr rate.
You can set up a proportion:
let x = number of miles per hour
$\frac{x}{180} = \frac{1}{2}$
cross multiply and you get
2x=180
divide both sides by 2 and you get
x=90
so you get the same answer both ways,
90 miles per hour
