Answer 38.6
Step-by-step explanation:
21 x .84 = 17.64
17.64 + 21 = 38.64
Ninety thousand five hundred twenty three
Answer:
49/144
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 49 and 144 is 1
Divide both the numerator and denominator by the GCD
49 ÷ 1
144 ÷ 1
Reduced fraction:
49
144
Therefore, 49/144 simplified to lowest terms is 49/144.
<span>Let pn = The total number of pizza crusts </span>made by the end of the nth week
For Pepe's Pizza:
Pn + 52 + 180n
For Diannes's
Pn = 25 + 90n
<span>The total number of pizza crusts made by Pep's Pizza equals twice the total number of pizza crusts made by Dianne's Delicatessen when:
52 + 180n = 2 (26 + 90n)
52 + 180n = 52 + 180n
</span>This equation is satisfied for any value of n, so Pepe's always makes twice as much as Dianne's
Answer:
The lines are perpendicular
Step-by-step explanation:
we have
isolate the variable y
----> equation A
The slope of the line A is 
-----> equation B
The slope of the line B is 
Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In this problem
The slopes of line A and line B are opposite reciprocal
therefore
The lines are perpendicular
