Answer:
the two angles are 55° each
Step-by-step explanation:
Let the two equal angles be y each
Therefore,
70° + y + y = 180°
Collect like terms
2y = 180 — 70
2y = 110
Divide both side by the coefficient of y i.e 2
y = 110/2
y = 55°
Therefore, the two angles are 55° each
Answer:
25 boys.
Step-by-step explanation:
To solve this problem, first add the two parts of the ratio. 9 + 5 = 14. Then divide 70 by 14 to get 5. Since the total is 5 times the ratio total, multiply both sides of the ratio by 5. The result is 45 : 25. If you add them together, you get a total of 70. Therefore, there are 25 boys in the class.
The correct statement is that the probability is B. Event F for female and event D for drama are independent events.
<h3>What are independent events?</h3>
It should be noted that two events are independent when the occurence of one doesn't affect the probability of another one occuring.
The probability of females will be:
= 3/5 = 0.6
The probability of drama will be:
= 40/240 = 0.167
In this case, they're both independent.

Answer:
198 / 9 = 22
Step-by-step explanation:
Answer:
C) -1
Step-by-step explanation:
(ax+3)²=36
<em>Square root both sides</em>
ax+3=6
<em>Subtract 3 from both sides</em>
ax=3
<em>Put x in</em>
-3a=3
a= -1
C) -1 would work.
