For this case we have to:
n: Represents the weight of Mary in Kg.
If your sister weighs 15 kg less we have:
Where "y" represents the weight of his sister in kg.
To find how many times Mary is heavier than her sister, we must divide Mary's weight by her sister's weight.
We have then:
Answer:
Mary is times heavier than her sister.
Answer:
m = 3/5
Step-by-step explanation:
Slope Formula:
Step 1: Find 2 coordinates
(0, 80)
(-50, 50)
Step 2: Find slope <em>m</em>
m = (50 - 80)/(-50 - 0)
m = -30/-50
m = 3/5
Answer:
<h2> D=C/4</h2>
Step-by-step explanation:
Given that elevation of the cities are
A=72 feet
C=24 feet
D=1/4 of C
The expression for the elevation of city D is
D=C/4
substituting C=24 in the expression we have
D=24/4
D=6
The answer is positive because the elevation is above sea level
the answer is $173.25( I had a question for this and i got it correct hope this helps)
The surface area of a rectangular prism is always:
A=2(xy+xz+yz), where x, y, and z are the three dimensions of the prism.
A=2(50*90+50*3.5+90*3.5)
A=2(4500+175+315)
A=2(4990)
A=9980 mm^2
