Answer:
the area is 10 feet by 10 feet, 100 feet²
subtract the area of the circle from this.
you get it by A = r² * pi
so 5² * 3.14159...
=78.5398163397
100-78.5398163397
is roughly 21.46 square feet
Answer:
-4 and 6
Step-by-step explanation:
Q1 is the median (the middle) of the lower half of the data, and Q3 is the median (the middle) of the upper half of the data. (3, 5, 7, 8, 9), | (11, 15, 16, 20, 21). Q1 = 7 and Q3 = 16. Step 5: Subtract Q1 from Q3.
Answer:
A. (3, -1)
Step-by-step explanation:
The ordered pair that is a solution is the one which makes the inequality TRUE when the value of the ordered pairs are plugged into 4x - 3y < 16
Therefore, the ordered pair, (3, -1) is the solution because it is the only given ordered pair in the options that makes the inequality true. Thus:
Substitute x = 3 and y = -1 into 4x - 3y < 16
4(3) - 3(-1) < 16
12 + 3 < 16
15 < 16 (TRUE)
Answer:
C(t) = 50 + 75t
Step-by-step explanation:
The electrician charges a set fee of $50. This fee is independent on the number of hours he spends in each house.
He charges an additional $75 per hour.
If the number of hours he spends working in each house is t, then, after t hours, the additional charges will be:
75 * t = 75t
The total cost, C(t) of the electrician's services is the sum of the set fee and the additional charges after t hours. That is:
C(t) = 50 + 75t
This is the function C(t), representing the total cost of the electrician's services.
