Answer:
you equate the given values to 180
The two expressions that would have the same product as 3.5 x 5.12 are:
184.32 x 1/12
76.8 x 3/12
<h3>What is the product of the a number?</h3>
The product of a number is the value that is derived when two or more numbers are multiplied by each other.
Product of 3 and 5.12 is 15.36.
In order to determine what number should be multipled by 1/12 to yield 15.36, multiply 15.36 by 12: 15.36 x 12 = 184.32
In order to determine what number should be multipled by 3/12 to yield 15.36, multiply 15.36 by 4: 15.36 x 4 = 76.8

Answer:
Step-by-step explanation:
(One tailed test)
Sample size n =250
x bar = sample mean =47
Mean difference =47-40 =7
Std dev =3.2 hours
Std error = 
Since population std dev not known t test to be used
t statistic = mean diff/stderror = 
df = 31
p value =0.000
p<Alpha
Hence there is evidence to prove that working hours exceed 40 hours.
Answer:
L=2.5
Step-by-step explanation:
P=2l+2w
The function given has the variables p, l, and w.
p = perimeter = 35
l = length = ?
w = width = 15
substitute the given values into the function.
p = 2l + 2w
35 = 2l + 2(15)
35 = 2l + 30
Subtract 30 from both sides of function.
5 = 2l
Divide both sides of the function by 2.
2.5 = l
The length is 2.5 feet.
