Answer:
19
Step-by-step explanation:
64 - 45 = 19
64 is the highest water collection time, while 45 is the lowest water collection time. You can tell by looking at the two lines at the end and beginning of the box plot.
Step-by-step explanation:
dividing every number by 10.
100:15:50
dividing every number by 5.
20:3:10.
this is the lowest term.
hope this helps you.
This is a perfect example of exponential decay. In this case the growth factor should be represented by a fraction, and it is! This forest, starting out with apparently ( 800? ) pine trees, has a disease spreading, which kills 1 / 4th of each of the pine trees yearly. Therefore, the pine trees remaining should be 3 / 4.
Respectively 3 / 4 should be the growth factor, starting with 800 pine trees - the start value. This can be represented as such,
- where a = start value, b = growth factor, t = time ( <em>variable quantity</em> )
____
Thus, the function can model this problem. The forest after t years should have P( t ) number of pine trees remaining.
Answer:
<6 , <8 , <3 are congruent to <1
Step-by-step explanation:
<6 = <1 ( being opposite Angles of parallelogram )
<8 = <6 ( being corresponding angles)
<8 = <1
<3 = <8 ( being opposite angles of parallelogram)
<3 = <1

Answer:
When did Mary and Wyatt meet? 0.5 minutes later
How far from point Q did they meet? 3.5 km
Step-by-step explanation:
Mary’s motion is represented by d = 8t----(1)
Wyatt’s motion is represented by 2d + 14t = 15----(2)
We solve for d in equation (2) to get:d=7.5-7t----(3)
We equate equation (1) and (3) to get:
We now solve for t to get:
Now put t=0.5 into equation (1) to get d=0.5*8=4
This means they met 4 km from point P.
Therefore they meet 7.5-4=3.5km from point Q
