Mathematics
1 answer:
sdas [7]3 years ago
8 0

Answer:

Mrs. Buggie should have Subtracted 13 instead of adding 13

LKA = 94°

Step-by-step explanation:

Lets work backwards from the equation so far:

40 = x+ 13

x + 13 = 40

We should subtract 13 because we are adding a number and 13 to 40

Imagine this:

You have 5 apples, but you bought some more and now you have 10

equation would be:

5+x = 10

subtract 5 from 10 to get 5

So you bought 5 apples

Back to the Question:

40 - 13 = 27

3(27) + 13 = 81+13 = 94°

Answer = 94°

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

Find the volume of each size stack by multiplying Length x width x height.

Once you have the volume for the 3 different stacks of books, add the together.

Bottom: 12 x 1 x 6 = 72 cubic inches per book x 2 = 144 cubic inches total.

Middle: 10 x 1 x 5 = 50 cubic inches per book x 2 = 100 cubic inches total.

Top: 7 x 0.5 x 4 = 14 cubic inches per book x 2 = 28 cubic inches total.

Total volume = 144 + 100 + 28 = 272 cubic inches.

Dale has $1,000 to invest. He has a goal to have $2,400 in this investment in 12 years. At what annual rate compounded continuou
Hatshy [7]

Answer:

9%

Step-by-step explanation:

Given that

The invested amount is $1,000

The future value is $2,400

The time period is 12 years

We need to find out the annual rate that compounded continously

So,

As we know that

Amount = Present value × e^(rate × time)

$2,500 = $1,000 × e^(rate × 12)

2.5 = e^(rate × 12)

ln 2.5 = 10r

ln 2.5 ÷ 10 = r

r = 9%
