Answer:
y=21
Step-by-step explanation:
y= 9 cos x =3 so y=3 when x=1 on the base level so if x=7 would be x=1 on the base level * 7 then y=3 on the base level * 7 would be y = 21
This is a combination problem. The approach to this is by using the nCr method, where n is the number of total objects and r is the number of success. For example, if you want to get 3 red out of the total 4, then that would be 4C3. That means,
4C3 = 4!/3!(4 - 3)! = 4 ways
If you want to get 2 green out of the total 6, then that would be 6C2. That means,
6C2 = 6!/2!(6-2)! = 15 ways
Therefore, there are a total of 4+15 = <em>19 ways</em>.
Answer:
The Answer is: The first number is 42 and the second number is 18.
Step-by-step explanation:
Let f = first number and s = second number.
f + s = 60
f - s = 24
Solve for f:
f = 24 + s
Substitute:
24 + s + s = 60
2s = 36
s = 18, the Second Number
Solve for f:
f = 24 + s
f = 24 + 18 = 42, the First Number
Proof:
42 + 18 = 60
60 = 60
Then:
42 - 18 = 24
24 = 24
Hope this helps! Have an Awesome Day!! :-)
If I'm doing this right, I think you start with 10 and add 16. So you'd have 26. Hope that helped a bit.
Answer:
2x+8=180° (being vertically opposite angles)
Step-by-step explanation:
2x+8=110°
or, 2x= 110-8
or, x=102°÷2
: x= 51 answer
