At hour 9 the river is 18 feet deep.
At hour 18 the river is 21 feet deep.
From 9 to 18 hours is 9 hours difference.
From 18 to 21 feet is a 3 foot difference.
The average rate of change is the change in depth divided by the change in time:
3 feet / 9 hours = 0.3 feet per hour. ( Rounded to the nearest tenth)
for the table its 30 * the hours +20 for example 30(1)+20=50 or 30(4)+20=140. the total cost is 30 times the hours plus 20.
<span>The rate for such investment is 4% per
annum. This will be computed as follows: $12,000 (Future value of money) less $10,000
( Present value of money) is equal to $2,000 which will be then divided by 5
years and the it will give us the value of $400 per year. Then $400 will be
divided by the $10,000 ( Present value of money) which gives us 4%.</span>
Answer:
x=16
Step-by-step explanation:
complementary means 90 degrees so
42 +3x = 90
3x=48
x=16
To figure out how many 8ths are in 48, you do 48/8=6
So 1/8 of 48 is 6
So to figure out 5/8 do
6*5=30
Hopefully this helps :D
