Answer:
4
Step-by-step explanation:
10 X 5 is 50. 200 / 50 is 4.
Answer:
x = 2
Step-by-step explanation:
Equation: 5x = 10
--- Divide 5 on both sides
x = 2
This means that each apple can make 2 cakes.
You can not call it domain cause it is only an expression not equation
you have to exclude 0 from domain
Option A is true because the sum of angles in a triangle is 180, so we can rule that one out immediately.
We can solve for x for the other 3 options by setting up this equation:
7x+2 + 4x+7 + 8x = 180 | Simplify
19x + 9 = 180 | Subtract 9
19x = 171 | Divide by 19
x=9
Now we can substitute x into all the values:
<J = 7x+2 = 65
<L = 4x+7 = 43
<K = 8x = 72
Looking at the options again, we can see that A, B, and D are true, leaving C to be false.
The correct question is:
The product of sin30 and sin60 is the same as the product of.............

Answer:
The product of sin30 and sin60 is the same as the product of cos60 and cos30.
Step-by-step explanation:
First of all, note that the following are correct:
cos60° = 0.5
sin60° = (√3)/2
cos30° = (√3)/2
sin30° = 0.5
sin30 × sin60 = 0.5 × (√3)/2 = 0.43301
Obviously, just by mere inspecrion,we see that
cos60 × cos30 = 0.5 × (√3)/2 = 0.43301
In conclusion, the product of sin30 and sin60 is the same as the product of cos60 and cos30.
