Answer:
- 4
Step-by-step explanation:
Step 1:
4 ( 2 - w ) + w = 20 Equation
Step 2:
8 - 4w + w = 20 Multiply
Step 3:
8 - 3w = 20 Combine Like Terms
Step 4:
- 3w = 12 Subtract 8 on both sides
Answer:
w = - 4

The answer is 1/4
Explanation
===============================
The question focuses on "if the student is known to be a boy..." we would obviously know that we would focous on only the total of the boys.
We have the formula for the probability of an event of happening which we would call event A (a boy being left-handed). P(A)= number of favorable outcomes/ total number of possible outcomes. The left-handers would go in the favorable outcomes since we want the probability of a boy being left handed and we would place the total boys in the total number of possible outcomes since all of them are going to be the one to be randomly picked. 50 left-handed/ 200 total boys. We have our fraction that is 50/200 as the probability but we can simplify it! We simplify 50/200 to get 1/4!!! 1/4 is the probability of a boy being picked that is left-handed!
Hope this helps!
Answer:
Step-by-step explanation:
Use the x-swap-y method to find the inverse:
Sum of inside angles of a polygon= 180º(n-2)
n=number of sides.
This polygon has 6 sides, the sum of all its angles would be=180º(6-2)=720
let´s:
xº=inside angle
xº=720º-sum of the others inside angles.
xº=720º-(75º+130º+120º+105º+145º)=720º-575º=145º
yº=180º-xº=180º-145º=35º
Answer: yº=35º
Answer:
the telephone polé is 24ft.
Step-by-step explanation:
30^2-18^2=b^2
900-324=b^2
576=b^2
\sqrt[576]=sqrt(b^2]
24=b
b=hight of telephone
