SVEN [57.7K]

Answer:

So the bigger array is 12 and 25

Step-by-step explanation:

Let's do a multiplication of this array first and Know it's result.

3 times five and 4 times 5. = (3*5) and (4*5)

= 15 and 20

Multiplying further gives us

= 15 * 20=300.

So to combine to get the bigger array.

We must get back 300 as the result of our product.

Let's multiply the row(x) with the row(x)

And the column (y) with column(y)

3 times five and 4 times 5.= 3*4 and 5*5

So the bigger array is 12 and 25

To check.

12*25 = 300

4. Peter is calculating interest earned on a deposit of $275 in an account that earns 8% simple interest after 12 years.
tatuchka [14]

Answer:

a) He substituted 0.8 instead of 0.08.

b) $264

Step-by-step explanation:

From the question, the principal is p= $275, the rate is r=0.08, and the time is t=12 years.

We substitute into the formula to get:

I=prt

I=275 \times 0.08 \times 12 \\ I=264

a) The mistake is that, he substituted 0.8 instead of 0.08.

b) The correct amount is $264
