4.781, 4.782,4.783,4.784,4.785
I can't explain though:(
Answer:
The best thing to do here is to put each of these into fractions, with the total (31) as the denominator.
14/31= silver
6/31= black
8/31= copper
3/31= various colours.
As you're looking for the keys that are silver or copper, you've got to add the two denominators together, which gives you 14+8= 22.
This cannot be simplified further, therefore, the probability of choosing either a silver or copper key is 22/31.
Hope this answer helps you :)
Have a great day

Answer:
19
Step-by-step explanation:
If you want to find the answer of the equation, sub the given information into it:
z + xz + y
we know that:
x = 5
y = 1
z = 3
We got:
= 3 + 5*3 + 1
= 3 + 15 + 1
= 19
Hope this helped :3
Answer:
B.
Step-by-step explanation:
So we know right off the bat the angles ABE and CBD are congruent because of vertical angles.
Now we can look at the sides.
The ratio for 27:18 = 3:2
The ratio for 36:24 = 3:2
They check out.
That means that the answer is B. SAS
