Answer:
$C = 0.30(m) + 15
C is bill cost
m is number of minutes used
Step-by-step explanation:
In this question, we are asked to write an equation that estimates the bill cost of Maggie’s phone bills.
We proceed as follows;
Now, let’s try and find the base fee.
We can calculate this using her bill for September.
Mathematically;
Bill = (Cost per minute * total minutes) + Base fee
Here, $0.30 per minute for 120 minutes will yield a total of 120 * 0.3 = $36
This means the base fee would be $51-$36 = $15
Now let’s say the bill is $C, and the number of minutes used is m
Mathematically;
$C = 0.30(m) + 15
It is based on powers of 10, making it logical.
Answer:
288in^3
Step-by-step explanation:
formula for volume is l*w*h
substitute the variables for 12*2*12=288
Thus the answer is 288in^3

Weighted mean average = ---------------------------
number of brands
value = mean price of computers from Store
#1 * number of brands from store #1 + mean price of computers from store #2 * number of brands from store #2
value = $799.99 * 2 + $679.99 * 4 = $4,319.94
number of brands = 2 + 4 = 6
weighted average = $4,319.94 / 6 = $ 719.99
Answer: option b. $719.99

Answer:
3rd quadrant
Step-by-step explanation:
- First we just convert the angle from radians to degrees
- Now that's too big, all this means is if we start rotating from the positive y-axis in a circle we will cross the starting point 2 times, 2 full circles;
- Now in which quadrant it 210 degrees?
- 0 degrees to 90 degrees is 1st quadrant
- 90 degrees to 180 degrees is 2nd quadrant
- 180 degrees to 270 degrees is 3rd quadrant
- 270 degrees to 360 degrees is 4th quadrant
- So our answer is the 3rd quadrant.
