The way to get the equation for the radius (r) is to get r by itself. So divide each side by 4pi
500/4pi=r^2
Now take the square root of each side to get the equation of r.
sqrt(500/4pi)=r
For the first one, since she earns $17 per hour, & she tutored for 12 hrs this month, all you have to do is multiply the amount she makes per hour by the hours she’s tutored for. so 12x17=$204 so she made $204 this month. For the second one, it’d be the same thing, just multiply 19.5 by 17, which would give you 331.5.
& For the second question, all you have to do is plug in the numbers to the equation above. so it’d be 540 gallons / 1 minute multiplied by 42 since that is the time the pool needs to be filled by. So, if you do that, you will get 22,680, so the answer will be : yes it will fill up on time.
A. y=3/2x
B. y=3/2x
C. 18
My Dad helped me with this.
Answer:
5$
Step-by-step explanation:
Since 1 kilogram equals 1,000 grams 5 potatoes equals 1,000 grams. 1,000 divided by 5 is 200. This means 1 potato has a mass of 200 grams 1,200 divided by 8 is 150. that means a pear has a mass of 150 grams. Since 200 grams is bigger then 150 grams, that means the potato has greater mass>
