Which ordered pair (x, y) can be added to the table so that y is still a function of x?

HELP ME WITH MATH!!! So basically I have to figure out how many hours that is between the times.

Ad libitum [116K]

Answer: (I think its correct)

1: 8 hours and 30 minutes

2: 8 hours

3: 8 hours and 50 minutes

4: 8 hours and 45 minutes

5: 7 hours and 48 minutes

6: 11 hours 13 minutes

7: 11 hours 31 minute

Step-by-step explanation: (Im bad at explaining it)

So I got this by using counting the hours in between the times and taking out the minutes in them,then subtracting the time they took the fall asleep. Every time that has minutes I add that, if it is over 60 minutes I subtract 60 minutes. So like 30+35=65 | 65-60=5.

Lets do a problem: 9:15 (bed) | 10:30(woke up) | 30 minutes (fall asleep)

So we count how many hours in each time and we take out the minutes, so 9:00, 10:00, 11:00, so on and so forth.

So in between the hours its was 13. Then we add the minutes (15+30)

15+30=45. So the answer is 13 hours and 45 minutes, but we got to subtract 13 hours and 45 minutes which is 13 hours and 15 minutes.

Final Answer: 13 hours and 15 minutes.

Question 1
----------------------------------------------------------------
a² + b² = c²
9² + 14² = c²
c² = 81 + 196
c² = 277
c= √277
c = 17cm (Rounded to the nearest whole number)

----------------------------------------------------------------
Ans: The Slanted height is 17cm (Answer C)
----------------------------------------------------------------

----------------------------------------------------------------
Question 2
----------------------------------------------------------------
Lateral area of the cone = πrl
1080π = π(60)l
l = 1080π ÷60π
l = 18.0cm

----------------------------------------------------------------
Ans: The slanted height is 18.0cm (Answer D)

In the image, point A marks the center of the circle. Which two lengths must form a ratio of 1 : 2?

Alex787 [66]

Answer: AI:EF

Step-by-step explanation:

1. By definition, the diameter of a circle is twice the radius, then:

D=2r

Where D is the diameter and r is the radius:

2. The AI is the lenght of the radius of the circle and EF is the length of the diameter of the circle. Keeping this on mind you have:

$\frac{AI}{EF}=\frac{r}{D}=\frac{r}{2r}=\frac{1}{2}$ or 1:2

3. Then, AI and EF form the ratio:

1:2

Answer:

Hey mate....

Step-by-step explanation:

This is your answer....

Yes, because a equilateral triangle has 3 equal angles. The 3 angles of a triangle equal 180°. So if the angles are all equal in an equilateral triangle, we do 60 times 3 which equals 180°.

hope it helps you,
