the lateral area and total area of regular pyramid with a square base is 130
Let :
T = Theresa age
H = her brother
We know :
T = H - 14
T + H = 35
Substitute T
H -14 + H = 35
2H - 14 = 35
2H = 49
H = 49/2 = 24.5
Since we know H = 24.5 we then can substitute it to either equation.
T = H - 14
T = 24.5 - 14
T = 10.5
Theresa is 10.5 years old
Her brother is 24.5 years old
Answer:
42 minutes is the median amount of time
Step-by-step explanation:
The Median is the middle value of data set.
If there is "odd" number of numbers, and there are n numbers, the median is:
(n/2) + 1 th number
If there is "even" number of numbers, and there are n numbers, the median is:
Average of n/2th and (n/2) + 1 th number
Here, we have 5 numbers, so the median would be:
(5/2) + 1 th number
That is
3rd number
But, we need to arrange the numbers from least to greatest. Lets write it:
19, 23, 42, 56, 67
The third number is 42, this is the median
Answer:
Around 30 times I believe
Answer:
Solution given:
9x-2y=7
making it in a form of y=mx+c
9x-7=2y
y=9/2x -7/2
Comparing above equation with y=mx+c
we get
m=9/2
Since it is passes parallel to (5,-3)
slope will be same
now
Equation of line
y-y1=m(x-x1)
y+3=9/2(x-5)
y=9/2x-5/2-3
<u>y=9/2 x-11/2 is a required equation.</u>
