When y = 4, x = 12...that means x is 3 times bigger than y. So if y = 1, then x will now = 1 x 3 = 3
Answer:
You can get the sale price one way or another way: 0.9 times p and p - 0.1 p.
The commutative property means that the numbers can be switched when multiplying. The second one shows the associative property, where the numbers can be grouped differently. The third one shows the identity property, where multiplying by 1 will get the same number you are multiplying it by. The fourth one shows the zero property, where multiplying by zero will get zero.
Therefore, the answer is the first one because the numbers are simply flipped.
Answer:
(a) The angle swept by the hour hand is 297⁰30′
(b) The exact angle between the minute and hour hand is 132⁰30′
Step-by-step explanation:
Given;
(a) angle swept by the hour hand between noon and 9:55 pm
between 12 pm and 9pm, there are 9 hours = 9 x 60 = 540 mins
9.55 pm = 540 mins + 55 mins = 595 mins
The hour hand moves 0.5 degree per minute
1 mins ---------------- 0.5 degrees
595 mins --------- ?
= 297⁰30′
(b) the exact angle between the minute and hour hands at 1:25 pm
for 25 mins, the hour hand had moved 12.5 degrees
Between 1 and 5, there are 20 mins moved by the minutes hand = 20 x 6°
= 120⁰
total angle = 12.5⁰ + 120⁰ = 132⁰30′
There are no 3s in 1/8... 1/8= 0.125
