If Zig were to shoot Marina in a 50 foot tank around a 30 foot radius circle, what is the distance of the circle?Gift for zig and sharks series!

Answers

Answer 1
Answer:

Answer:

The distance of the circle is 314 foot .

Step-by-step explanation:

Given as :

The measure of tank = 50 foot

The radius of circle = 30 foot

Let The distance of circle = x foot

Now, Distance of circle = circumference of circle

∵ circumference of circle = 2 × \pi × radius

where  \pi = 3.14

∴  circumference of circle = 2 × 3.14 × 50

I.e  circumference of circle = 314 foot

So, Distance of circle = 314 foot .  

Hence the distance of the circle is 314 foot . Answer

You estimate that there are 44 marbles in a jar. The actual amount is 73 marbles. Find the percent error.

Answers

Answer:

Percentage Error in counting the marbles in the jar is 39.72%

Step-by-step explanation:

Estimated marbles in the jar = 44

Actual marbles in the jar  = 73

⇒Error in  Marbles  =  Number of actual Marbles - Estimated marbles

                                 =   73  - 44 = 29

So, the error in counting marbles in the jar is 29.

Now, \textrm{Percentage Error}  = \frac{\textrm{Error in the Data}}{\textrm{Actual Data}}  * 100

= (29)/(73)  * 100  = 39.72

or, Percentage Error  =  39.72%

Hence, the Percentage Error in counting the marbles in the jar is 39.72%

Solve the equation
4.8y-6.9=3.18
Explain your thinking

Answers

4.8y - 6.9 = 3.18 
4.8y= 3.18 + 6.9 (I added 6.9 to both sides)
4.8 y = 10.08 (I added 3.18 by 6.9)
y = 2.1 (I divided 4.8)

Hope this helps!!
the point of this equation is to figure out the value of the y variable. to do this, you'll need to get the y variable by itself on one side of the equation. 

so first you would add 6.9 to 3.18. 
the equation would now look like this: 
4.8y=10.08 


you would then divide 4.8 by 10.08. this is the last step to getting the y varible by itself on one side of the equation and ultimately the value of y! 
the equation now looks like this: 
y=2.1 

y=2.1 is you answer!
Good luck!
