Lucy has 20 questions in her science home work
<em><u>Solution:</u></em>
Given that,
Lucy correctly answered 70% of the questions on her science homework
She counted 14 correct answers on her paper
<em><u>To find: Number of questions in her science home work</u></em>
Let "x" be the number of questions in her science home work
From given we can say,
Lucy correctly answered 70% of questions
She counted 14 correct answers
70 % of total questions = 14 correct answers
70 % of x = 14

Thus Lucy has 20 questions in her science home work
Answer:
(8x + 1)° + ( 4x+11)° = 180° (linear pair )
8x +1 + 4x +11 = 180
8x + 4x + 1 + 11 = 180
12x + 12 = 180
12x = 180 - 12
12x = 168
x= 168/12
x = 14
Answer:
1/1080
1/3
y=cos(x/3)
Step-by-step explanation:
just did it
Answer: The point (0,0)
This point is also known as the origin
The reason why is because every direct variation equation is of the form y = k*x
where k is some fixed number
If we plugged in x = 0 it leads to y = k*x = k*0 = 0. So (x,y) = (0,0)
