Answer:
Length: 23.38
Width: 3.34
Step-by-step explanation:
First I drew out a diagram so that I could visibly see the problem. [ a rectangle with 7x on one side and x on the other.
So to find the area you multiply length time width and 7x times x is 7x^2. The actual area is given: 78, so you set that equal to 7x^2.
Then you want to divide by 7 to get 11.14. Then you want to take the square root of 11.14 to get 3.338 which rounds to 3.34 {try not to round until the very end]. This gives you the width of the rectangle, so to find the length you would have to multiply x by 7 to get 23.38. When you multiply the length and width (3.34 x 23.38) you get 78.08 which can round to 78.
7x^2 = 78
x^2 = 78/7
x^2= 11.142...
x = sqrt(1.142...)
x = 3.338 --> 3.34 --> width
3.34 x 7 --> 23.38 --> length
3.34 x 23.38 --> 70.8
Answer:
C. the largest value of that class
Step-by-step explanation:
Class limit is like an interval it has the lowest value and largest value and the all values between these lower and upper values lie within that class.
Hence, the Upper Class limit of a class is the largest value of that class.
Thus, only option C is correct.
#2.
a) 1/4m + 3 = 2
1/4m = -1
m = -4
b) 4y - 3(y + 8) = 12
4y - 3y + 24 = 12
y = -12
For #10, letter b. Do the same thing you did with letter a.
The equation is already given.
You have your y-intercept: -8, and your slope: 3/1.
These two create two different points you can add to your data table.
(0, -8) and (1, 3)
y:-8, 3
x: 0, 1
The answer to the question
i think this is your answer: 12.0 and 12.5
