Answer:

A. 355 Square inches

Step-by-step explanation:

Multiply length (l) x width (w) on each section. 45x5 = 225

10 x 10 = 100 and 6 x 10 = 60/2 = 30 (since it is a triangle you divide by two)

Add them all up, 225 + 100 + 30 = 355 square inches

The local movie theater collected a total of 8250 last night, of which 45% came from sales at the concession stand. How much mon

The theater collected $3,712.50 at the concession stand. How I determined this answer:

Alright, so you already know the total amount the theater collected ($8,250) and the percent of sales which came from the concession stand (45%). Your first step is to change the given percentage into a decimal, as shown below:

To change 45% into a decimal, you have to move the invisible decimal point two places to the left:
45(.)% becomes .45

Now that you have changed your percent into a decimal, your next step is to multiply the total sales the theater made last night with your decimal, as shown below:

Multiply the total sales ($8,250) x (.45)
$8,250 x .45 = $3,712.50.

So the theater made a total of $3,712.50 at the concession stand last night.

NEED HELP WITH THIS ASAP FOR PLATO WILL MARK BRAINLIEST

Answer:

-Ella have enough money($16,188.21) saved in six years to buy her home.

-It will take just over 10 yrs(10.24 yrs) for Ella’s account balance to exceed $20,000.

Step-by-step explanation:

#5% interest, compounded monthly, we calculate the effective annual interest rate:

$i_m=(1+i/m)^m-1, m=12, i=0.05\\\\i_m=(1+0.05/12)^{12}-1\\\\i_m=0.0511619$

The principal amount is $12,000 and the desired term is 6yrs. We calculate the compounded amount after 6yrs at $i_m$ :

$A=P(1+i_m)^6\\\\=12000(1.0511619)^6\\\\=16188.21$

Hence, Ella wont be able to make a down-payment at the end of 6 yrs since her investment of $16,188.21 <$20,000

To get how long she will be able to make the down-payment, we equate and make n the subject of the formula:

$A=P(1+i)^n\\\\20000=12000(1.0511619)^n\\\\\frac{5}{3}=1.0511619^n\\\\n=\frac{log \frac{5}{3}}{log \ 0.0511619}\\\\=10.24\ yrs$

Hence, it will take just over 10 yrs for Ella’s account balance to exceed $20,000.
