in order to get the percentage you would just need to divide 6,840 by 38,000 (6840/38000 = .18)

this gives you .18

.18 is equivalent to 18%

Evaluate the expression: -|-14| HELPPPPPPPPPP!!!!!! (its worth all my points!!) ( ik its sad
Serhud [2]

Answer: -14

Step-by-step explanation: Here we're asked to simplify -|-14| so we

start by simplifying the absolute value of -14.

Remember that the absolute value of

any positive or negative integer is positive.

So the absolute value of -14 is 14.

So we write (14) in parenthses like I have just done.

Next, we bring down the negative sign

that was outside the absolute value.

So we're left with -(14) or -14.

A 4 foot tree was planted in 2012 outside a high school. The tree grew continuously by 22% each year from that point. Find out w
Brut [27]

Answer:

The height of the tree in 2020 was of 19.63 feet.

Step-by-step explanation:

Exponential equation for growth:

The exponential equation for the growth of an amount has the following format:

H(t) = H(0)(1+r)^t

In which H(t) is the amount after t years, H(0) is the initial amount and r is the growth rate, as a decimal.

A 4 foot tree was planted in 2012 outside a high school.

This means that H(0) = 4

The tree grew continuously by 22% each year from that point.

This means that r = 0.22

Find out what the height of the tree was in 2020.

2020 is 2020 - 2012 = 8 years after 2012, so this is H(8).

H(t) = H(0)(1+r)^t

H(t) = 4(1+0.22)^t

H(4) = 4(1.22)^t

H(4) = 4(1.22)^8 = 19.63

The height of the tree in 2020 was of 19.63 feet.
