1) 40+7=47
2) 47+7= 54
3) 54+7 = 61
4) 61+7 = 68
The answer is 68.
Answer:
cos(A) = 4/5
Step-by-step explanation:
3sinA+4cosA=5
Divide by 5 on both sides
(3/5)sinA+(4/5)cosA = 1 .................(1)
from which sin(A) = 3/5, cos(A) = 4/5 by inspection, since
(3/5)^2+(4/5)^2 = 1
For more details,
Let
cos(B) = (3/5), then
sin(B) = (4/5)
Substitute in (1)
cos(B)sin(A) + sin(B)cos(A) = 1 substitute trigonometric sum
sin(A+B) = 1 => A & B are complementary
cos(A) = sin(B) = 4/5
These are a lot of math problems that you should ask ur teacher about if you are having trouble.
You should also be more responsible.
Answer:
11/36
Step-by-step explanation:
So here’s the probability of rolling one three or more on one dice:
2,3
1,3. 5 chance of at least one 3 on this dice
4,3
5,3
6,3
On other die:
3,2
3,4
3,1
3,5
3,6. 6 chance of rolling at least one 3 on this dice
3,3
5+6=11
11/36 possible combinations contain at least one three
Hope this helps!
