An actor invests some money at 7%, and $48000 and more than twotimes the amount of 9%. The total annual interest earned from the
forsale [732]

Answer:

At 7% $54,000

At 9% $156,000

Step-by-step explanation:

Let x be the amount invested at 7%, Then 2x + 48000 will be the amount invested at 9%

We know that:

7% = 0.07 & 9% = 0.09

So we can write the interest equation as follows:

0.07x + 0.09 (2x + 48000) = 17820

0.07x + 0.18x + 4320 = 17820

0.25x + 4320 = 17820

Subtracting 4320 from both sides of the equation we get:

0.25x = 17820 - 4320

0.25x = 13500

Dividing both sides of the equation by 0.25 we get:

x = 13500 / 0.25

x = $54,000 invested at 7%

&

2 x 54000 + 48000

= $156,000 invested at 9%

Hence the amount invested at 7% is $54,000.

& the amount invested at 9% is $156,000.

Niko has an orange tree and a lemon tree in his backyard the orange tree is 7 feet tall 9 inches tall the lemon tree is 1 yard 2
Dennis_Churaev [7]
We can solve this by converting both measurements to inches.

Orange tree:
1 foot=12 inches
7 feet=84 inches
84 inches + 9 inches = 93 inches total

Lemon tree:
1 yard=3 feet=36 inches
2 feet=24 inches
36 inches + 24 inches + 5 inches=65 inches total

Therefore, the orange tree is taller than the lemon tree.

42/40 into a mixed number is??
SSSSS [86.1K]
Hello there!

So, as we see that 42 is more than the denominator, so, we would have to see by how much it would be over.

40-42=2.

So, sense we have an whole number which would be (1)

Your answer: \boxed{\boxed{\bf 1\frac{2}{40} }}
