Seth invested n dollars into an investment fund last year. After a period of one year, the value of his investment can be repres
Crank

Answer: A. The value of his investment decreased by 16% during this time period.

Step-by-step explanation:

Here the initial amount = n

Final amount after 1 years = 0.84n

The total change in the initial amount = n - 0.84n = 0.16 n

\text{ The percentage change in the initial amount} = \frac{\text{ the total change in initial amount}}{\text{ Initial amount}}\times 100

= \frac{0.16 n }{n} \times 100 = 16\%

Thus, the amount is decreases by 16% in one year,

⇒ Option A is correct.

Eight less than 7times a number is -29
Alona [7]
7n-8=-29
You got the equation correct. 
I'm not sure if you want me to solve n but I'll do it in case you need help on that.
First, add 8 on both sides which would equal 7n=-21.
Now, divide 7 on both sides.
n=-3
Hope this helps

Find the area of the circle to the nearest hundredth with r=4cm. d=18in.<br>​
Annette [7]

Answer:

  • 1.

r = 4 cm

A(circle) = π·r²

= π·(4cm)²

= 3.14·16cm²

= 50.24 cm²

  • 2.

d = 18 in

d = 2r => r = d/2 = 18in/2 = 9 in

A(circle) = π·r²

= 3.14·(9in)²

= 3.14·81in²

= 254.34 in²
