The second salesperson is correct. The ratio is 1/16.
In order to find the correct ratio, you first have to turn the actual bridge length into feet. You do this by multiplying the yards by 3.
6 2/3 yards * 3 = 20 feet.
Now we can divide the painting length by the actual length to compare.
1.25ft / 20ft = 1/16
Answer:
62.8 inches
Step-by-step explanation:
c = πd
c = 3.14 * 20
c = 62.8 inches
If the perimeter of a square is 16a + 20ab inches, then that means that:
1) s + s + s + s = 16a + 20ab
2) s² = 16a + 20ab
Where s represents one side of a square.
Factoring the expression 16a + 20ab. We can factor this binomial using the greatest common factor. What do both terms 16a and 20ab have in common? Theyre both divisible by 4a. So, we can factor out a 4a from the expression.
16a + 20ab
= 4a(4 + 5b)
The expression 4 + 5b does not represent the length of one side of the square. Why? Because if we multiply 4 + 5b by itself, we will not get 16a + 20ab.
(4 + 5b)(4 + 5b)
= 16 + 20b + 20b + 25b²
= 16 + 40b + 25b²
We can, ultimately, determine the length of one side of the square by dividing the expression by 4.
16a + 20ab / 4
= 4(4a + 5ab) / 4
Cancel out the 4 from the numerator and denominator.
= 4a + 5ab
Check to see if the expression will get you 16a + 20ab.
= (4a + 5ab)(4)
= 16a + 20ab
According to my calculations Lauren used 147 minutes her first month.
72.75-36=36.75
36.75/.25=147
Answer:
5
Step-by-step explanation:
6a = (a*-3) + 45
then:
6a = -3a + 45
6a + 3a = 45
9a = 45
a = 45/9
a = 5
Check:
6*5 = (5*-3) + 45
30 = -15 + 45
