The square is put on the units when it is the area of a 2D shape and you cube the units when it’s the area of a 3D shape.

Answer:

Volume: 864

Surface Area: 684

Step-by-step explanation:

Volume:

$\frac{1}{2}(9 * 16 * 12) = 864$

Surface-Area: (Pretty Self-explanatory)

1. Triangles - 12 * 9 = 108 (You don't need to divide it by two, just leave it as is because there are two of these triangles.)

2. Base - 16 * 9 = 144

3. Height/Base - 12 * 16 = 192

4. 15 * 16 = 240

192 + 144 + 108 + 240 = 444

The Surface Area is 684.

Alice earned $622.50 in interest on her savings in the bank. Before interest, the account had $12,450. What is the approximate p

Lubov Fominskaja [6]

Answer:

Explanation:

% she earned in interest can be calculated by calculating the % of increase in the balance

We have:

Original balance = $12,450

Amount of interest = $622.5

This means that:

new balance = 12,450 + 622.5 = $13,072.5

Now, we can get the percentage of increase:

% of increase = $\frac{Value_n_e_w - Value_o_l_d}{Value_o_l_d} *100$

Substitute with the values we have to get the percentage of interest earned as follows:

% of interest earned = $\frac{13072.5 - 12450}{12450} * 100$ = 5%

Hope this helps :)

puteri [66]

Answer:

she invested 6600 at 3% and 3400 at 2.5%

Step-by-step explanation:

Simple interest = amount deposited x time x interest rate

Let the amount deposited in in the account bearing 3% interest by represented with a

Let the amount deposited in in the account bearing 2.5% interest by represented with (10,000 - a)

a x 0.03 + (10,000 - a) x 0.025 = 283

0.03a + 250 - 0,025a = 283

collect like terms

0.03a - 0.025a = 283 - 250

0.005a = 33

a = 6600

the amount deposited in the 2.5% account = 1000 - 6600 = 3400
