Answer:
The first one
Step-by-step explanation:
When you do a reflection across the y-axis, it is like a mirror. And if you have a generic point (x, y) the new point will be (-x, y).
In the table you have 4 points:
(x,y)
(-3,9)
(0,0)
(2,4)
(5,25)
The new points will be:
(3,9)
(0,0)
(-2,4)
(-5,25)
Jenny does, she bakes 12 for every x and dan bakes 10 for every x.
So in conclusion jenny bakes more cookies per batch
Use PEMDAS. 20/(4*5)=1
Multiplication before dividion
Answer:
If there is 1 at the top, then you have 1, then 2, then 3, etc.
total number of oranges equals:
1 + 2 + 3 + ... + 16 + 17 + 18 <-- stop at 18 because this is the number of oranges at the base
You can use the formula:
sum of first n numbers = n*(n + 1)/2
-->
18*19/2 = 9*19 = 171
or you can figure it out (basically derive the above formula):
you have:
1 + 18 = 19
2 + 17 = 19
3 + 16 = 19
...
How many pairs do you have? Well, it's just the number of numbers: 1-18 = 18 numbers (divide by 2) = 9 pairs)
9 pairs of 19 = 9 * 19 = 171
Hope this helps!
Step-by-step explanation:
The answers is 14%
49 multiply by 14% is 6.86
42.14 + 6.86= 59
