Answer:
length: 16 m; width: 13 m
Step-by-step explanation:
Write each of the statements as an equation. You know that the formula for the perimeter is ...
P = 2(L +W)
so one of your equations is this one with the value of P filled in:
• 2L + 2W = 58
The other equation expresses the relation between L and W:
• L = W +3 . . . . . . . . the length is 3 meters greater than the width
There are many ways to solve such a system of equations. Since you have an expression for L, it is convenient to substitute that into the first equation to get ...
2(W+3) +2W = 58
4W +6 = 58 . . . . . . . simplify
4W = 52 . . . . . . . . . . subtract 6
W = 13 . . . . . . . . . . . .divide by 4
We can use the expression for L to find its value:
L = 13 +3 = 16
The length is 16 meters; the width is 13 meters.
Answer: 9
Step-by-step explanation:
27÷3=9 if you need one third cup per bowl then you need to divide the number of the bowls by three
Answer:
5
Step-by-step explanation:
so X-5=0.1 (x+5)
x is 5
+ 5-5=0.1
X= 3 to x = 4 has a greater rate of change
Answer:
The value of test statistic is -2.
Step-by-step explanation:
The following information is missing in the question.
The population mean is 12 minutes.
We are given the following in the question:
Population mean, μ = 12 minutes
Sample mean, 
= 8 minutes
Sample size, n = 36
Population standard deviation, σ = 12 minutes
Formula:
Putting all the values, we have
The value of test statistic is -2.
