The correct answer is 48%
There are 10 even numbers from 1 to 21.
That makes the probability of an even number 10 out 21.
10 / 21 x 100 = 48%
Answer:
Step-by-step explanation:
So the area of a cube is a²
This means that:
2² = 4cm²
So the area of a triangle is (b*h)/2
This means that:
(3*2)/2 =
6/2 = 3cm²
4cm² + 3cm² = 7cm²
Overall area is 7cm².
Answer:
After 6 days, 3 bottles will be left.
Step-by-step explanation:
Given that:
Number of bottles = 15
Number of bottles drank each day = 2
Let,
d be the number of days
y be the number of bottles left
y = 15 - 2d
Now,
We have to find the number of days when 3 bottles will be left.
Putting y=3
3 = 15 - 2d
2d = 15 - 3
2d = 12
Dividing both sides by 2
Hence,
After 6 days, 3 bottles will be left.

Answer: y = 3x+18</h3>
Slope = 3
Y intercept = 18
==================================================
Work Shown:
m = slope
m = (y2-y1)/(x2-x1)
m = (0-(-9))/(-6-(-9))
m = (0+9)/(-6+9)
m = 9/3
m = 3 ... is the slope
-------
y = mx+b
y = 3x+b .... plug in the slope
-9 = 3(-9)+b ... plug in the point (x,y) = (-9,-9)
-9 = -27+b
-9+27 = -27+b+27 .... adding 27 to both sides
18 = b
b = 18 ... is the y intercept
---------
We found that m = 3 is the slope and b = 18 is the y intercept
y = mx+b turns into y = 3x+18
No. Amelia wouldn't be able to go three weeks without getting the notification.
3×7=21
300÷15=20 means that in twenty days time, Amelia will have withdrawn ALL of her money.
That time period doesn't allow for Amelia to even reach the last day of the third week (21 days).
