Hello, right answer is B) twice the original number
If you divide a number for a fraction, you are multiplying that number for the opposite of that fraction (so 1/2 = 2)
This means 4 : 1/2 = 4*2 = 8
Instead, if you multiply a number for 1/2, you are dividing it for 2.
Hope it helps :)

Answer:
50
Step-by-step explanation:
first of all thimk about how many 12s there is in 60 (which is 1hr=60) and thats 5, so multiply 5 by 10 because in each 12 mins its 10 km which gives you 50 as the answer
Answer: a = 0
Step-by-step explanation:
ok we got
. Our task is to choose a value for
so that "the tangent line to
at
passes through
."
Well
, and
. So our tangent line looks like this:
![y - 3 = (4 + a)(x - 1)](https://tex.z-dn.net/?f=y%20-%203%20%3D%20%284%20%2B%20a%29%28x%20-%201%29)
![y = 4x + ax - a - 1](https://tex.z-dn.net/?f=y%20%3D%204x%20%2B%20ax%20-%20a%20-%201)
We know this must contain the point
, so
![2a + 7 = 4(2) + a(2) - a - 1](https://tex.z-dn.net/?f=2a%20%2B%207%20%3D%204%282%29%20%2B%20a%282%29%20-%20a%20-%201)
![a = 8 - 7 - 1\\\\\boxed{a = 0}](https://tex.z-dn.net/?f=a%20%3D%208%20-%207%20-%201%5C%5C%5C%5C%5Cboxed%7Ba%20%3D%200%7D)
Answer:
Regular dance exercise improves the endurance of body muscles, allowing them to work harder for longer periods of time without feeling tired. Dancing also raises the body's heart rate to heighten stamina. You'll be jumping out of bed each morning in no time.
