Create equations:
10X+15y=2575.
X+Y=210.
Solve for X: X=210-Y, and sub it into the other equation: 10(210-Y)+15Y=2575. Solve for Y: 2,100-10y+15y=2575, 5y=475, y=95.
Sub Y into the original problem: X+95=210. Solve: X=115.
The first mechanic charges $115 per hour and the second charges $95 :)
The hours worked would be 7 and 10 minutes.
20/5=4
25/7=<span>3.57142857143 Rounded to the nearest tenth: 3.6
4>3.6
If you want the nearest whole, you would round down to 3 because you would be short of 4.
3<4 </span>
We have that
A(-4,-4) B(-2,5) C(2,1) D(2,-4)
step 1
find the distance AC with the formula
d=√[(y2-y1)²+(x2-x1)²]------> dAC=√[(1+4)²+(2+4)²]----> dAC=√61 units
dAC=√61-----> dAC=7.8 units
the answer is
the option
<span>B. 7.8 units</span>
Answer:
C. The median for town A, 30°, is less than the median for town B.
Step-by-step explanation:
A box plot can clearly represent the median as a center of the distribution of a data set.
Thus, the median of a box plot is depicted by the vertical line that divides the rectangular box.
Therefore:
Town A Median temperature = 30°
Town B Median temperature = 40°
The standby that best compares their centers is:
C. "The median for town A, 30°, is less than the median for town B."
