Find the AREA of a circle with a diameter of 62 ft. Use 3.14 for the value of pi.
Answer:
3017.54
Step-by-step explanation:
62/2=31
31 x 31 x 3.14=3017.54
Answer:
3017.54
Step-by-step explanation:
A = πr²
The radius is half of the diameter so you divide 2 into 62.
62/ 2 = 31
31 x 31 = 961
961 x 3.14 = 3017.54

Answer:
Quadratic function, None of the above, and ?
Step-by-step explanation:
So remember what I told you about earlier, lets look at that first one.
So we can see that x is increasing by 1 and y is decreasing by 3...And then it increases by 3! And after that another 9! Well, that seems like it is reversing, as it changes from decreasing to increasing in y coordinates. So knowing that is reverses from decreasing to increasing in y, it must be a quadratic function!
Next we have a increase in 1 and a decrease by 17...then 12...then 7 in y. This isnt decreasing by a constant amount like a linear function. It doesnt seem like a obvious exponential decrease either, and it isnt reversing like a quadratic function does. I am going to use something called logarthms, which you don't even need to think about yet, just to make sure that it is not an exponent. Althouhg the difference in the exponent was only 0.0018, it is a differnece. So this must be a none of the above, sicne none of the functions apply. (If this is incorrect, and it is exponential, then the test is wrong. While the method I used is something found in mid algebra 2, it is still a method of finding a exponent of a number.)
Now we finish up with a change in x of 1, and a change of y by...-11, -11, -11!
Well, what do you think this is, thinking back on what I have said so far.
It is a constant change of -11y and 1x. Remember, a CONSTANT CHANGE.
What do you think it is :)
If you cannot figure it out, let me know in comments.

Answer:
I think T is the independant and B is the dependant
Step-by-step explanation:
the amount of time they have is not changed, however the amount of bands they can fit into that time slot is undetermined and relies on the time they have
Answer:
the first option
Step-by-step explanation:
independent is something you can change OR determine
dependent is something that will happen BECAUSE of the independent and you can not change it
in this case- the sentence states that " the amount of time that the venue has been reserved for DETERMINES how many bands will play"
You can change or schedule how long you want to reserve the venue but how many bands that will play depends on the independent variable (t)
Thats why it say determines, because (t) determines or changes (b)

Find the missing angle measure in an obtuse triangle with angle measures of 10 degrees and 15 degrees
Answer:
Missing angle is 155°
Step-by-step explanation:
All triangle angles add up to 180 so:
x + 10 + 15 = 180
x + 25 = 180
x = 180 - 25
x = 155

Solve 4/9 plus x =7/9 x =
Answer:
x = 1/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x + 4/9 = 7/9
Step 2: Subtract 4/9 from both sides.
x + 4/9 - 4/9 = 7/9 - 4/9
x = 1/3
Answer:
x = 1/3 (or) 3/9
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
The equation is,
→ (4/9) + x = 7/9
Then the value of x will be,
→ (4/9) + x = 7/9
→ x = (7/9) - (4/9)
→ x = (7 - 4)/9
→ x = 3/9
→ [ x = 1/3 ]
Hence, the value of x is 1/3.
Solve for x.

The data set shows the individual scoring totals for the players on the losing team in the 2012 NBA Finals.
Answer:
Median: 7.5
Lower Quartile: 1
Upper Quartile: 12.5
Step-by-step explanation:
First, arrange the numbers in numerical order.
0,0,1,2,3,7,8,11,13,16,27,32
Now find the middle of the data set, which is 7.5, because you add the 2 middle numbers (7 and 8) and then divide by 2. So your median is 7.5
Now you need to find the medians of the upper and lower quartiles. Spilt the data set into thirds.
(0,0,1,2),(3,7,8,11),(13,16,27,32)
Now find the medians.
For the lower quartile, the median is 1. For the upper quartile, the median is 12.5 .
Please let me know if this correct!! Have a great day!! :)
