Answer:
b=6
Step-by-step explanation:
9/b=21/14
9/b=3/2
9=3/2b
9=3b/2
9×2=3b
18=3b
18/3=b
6=b
b=6
X * y = 50
y = 50 / x
S = x + y = x + 50 / x
S` = 1 - 50 / x²
1 - 50 / x² = 0
50 / x² = 1
x² = 50
x = √ 50 = 5 √2
y = 50 / 5√2 = 5 √2
Answer:
Those numbers are: x = 5√2 and y = 5√2.
The only thing that we have to do in this problem is to
convert the units.
We know that:
1000 g = 1 kg
100 cm = 1 m
Therefore:
density = (2.7 g / cm^3) * (1 kg / 1000 g) * (100 cm /
m)^3
<span>density = 2700 kg / m^3</span>
Answer:
x = 3
Step-by-step explanation:
We can use the following equation to solve for x:
