Answer:

25,800

Step-by-step explanation:

-150(4) + 50,000 = 49,400

50(4) + 75,000 = 75,200

75,200 - 49, 400 = 25,800

you consistently deposit 250.00 into a savings account on the 15th of each month, and the amount earns a 2.5 APR How much is the

frosja888 [35]

Answer:

Balance of savings account at the end of 3rd month = $753.13

Step-by-step explanation:

Balance at the end of 1st month :

Principal = $250 , Time = 1 month , n = 12 , APR = 2.5%

$\text{Compound Interest = }Principal\times (1+\frac{rate}{n\times 100})^{n\times Time}\\\\=250\times (1+\frac{2.5}{12\times 100})^{12\times \frac{1}{12}}\\\\=\$250.52$

Balance at the end of second month :

Principal = 250 + 250.52

= 500.52

Time = 1 month, APR = 2.5%, n = 12

$\text{Compound Interest = }500.52\times (1+\frac{2.5}{12\times 100})^{12\times \frac{1}{12}}\\\\=\$501.56$

Balance at the end of third month :

Principal = 250 + 501.56

= 751.56

Time = 1 month, APR = 2.5%, n = 12

$\text{Compound Interest = }751.56\times (1+\frac{2.5}{12\times 100})^{12\times \frac{1}{12}}\\\\=\$753.13$

Hence, Balance of savings account at the end of 3rd month = $753.13

Geometry, Multiple choice. Answer all if possible. Ty

Eddi Din [679]

Question 2: The answer is A. 90, 45, 45 because one angle is a right angle which is always 90 degrees and the two remaining angles are the same. Also, all triangles have to have a total amount of 180 degrees when all angle-degree-measurements are combined, which leaves A as the only possible answer.

Question 3: The answer is D. To solve this question you simply multiply all the dimensions of the triangular prism together. That would be: 10 x 14 x 8 = 1,120 in squared

Question 4: Sorry, didn't get this one :(

Question 5: The answer is B. 4pi. Sorry, don't have a good explanation for this one, but I'm pretty sure it is correct.

Question 6: Can't see the question, so I can't help you :(

Question 7: The answer is A. 5 feet. Using the power of elimination you can conclude that the three other options to the answer are improbable.

Question 8: The answer is B. 180 - x. To get this you need to know that 180 degrees is a flat line angle. Since angle x and angle y stem from the same two flat lines intersecting diagonally, you can determine the 180 - angle x would equal angle y.

<h3>What is a Rectangle ?</h3>

A rectangle is a polygon with four sides , opposite sides are parallel and equal.

It is given that

A rectangle is divided into exactly 20 congruent squares

If they are lined up the Length is 36 inches

Therefore the length of each square or the side of the square = 36/20

= 1.8 inch

The area of the rectangle will be

20* Side of square * Side of square

=20*1.8*1.8

= 64.8 square inch

The area of the rectangle is 64.8 square .inch
