3 ( 14-8) =18
B= 14
I subtracted 14-8 and i got 6, then I multiplied 3 times 6 and got 18. Therefore, 14 is a valid answer.
Answer:
y = -3x - 3
Step-by-step explanation:
the y-intercept is -3 as shown in the graph, so, b = -3
if you count, the rise is 3 and the run is -1, so the slope will be -3/1
-3/1 equals to -3
y = -3x - 3
Answer:
<u>Percent air is calculated as:</u>
- Percent air = Current amount/Total amount *100
<u>Solve for total amount of air:</u>
- Total amount = Current amount / Percent air * 100
Substitute the values in hand to get the answer
Answer:
Average rate of change in amount of the element over 10 minutes is 0.15 per minute.
Step-by-step explanation:
Given question is incomplete; find the attachment of this question attached with the answer.
In this experiment change in amount of the element has been plotted on y-axis and duration (time) on x-axis.
Change in amount of the element during 0 to 10 minutes = 1.5 units
Now the duration of this change in amount = 10 minutes
Therefore, rate of change in amount of the element =
= 0.15 units per minute
A. 10 feet.
Think of it like this:
The wall is upright, it's 90° and it's 8 feet high. The distance from the bottom of the ladder to the bottom of the wall (along the ground, which is perpendicular to the wall) is 6 feet. When Benton places the base of the ladder 6 feet away from the wall and the top is resting at the top of the wall, it looks like a triangle, right?
Using pythagoras (this rule about right-angled triangles and stuff), we can already see that the two sides when simplified are 3:4. Because the 'triangle' is a right-angled triangle, the other side HAS to be 5 to complete the ratio. We just multiply it by 2 to get the correct ratio and that's your answer!
