To find 75% of 200, we can multiply two fractions.
75/100 * 200/1
Now, just multiply the numerators and the denominators separately.
75 * 200 = 15000
100 * 1 = 100
Now, divide.
15000/100 = 150
<h3>75% of 200 is 150.</h3>
Answer:
n = 1.2
Step-by-step explanation:
3n = 3.6
Divide both sides by 3 to get n by itself.
3.6/3 = 1.2
n = 1.2
Answer:
5,000,000
Step-by-step explanation:
X=length
y=width
Area (rectangle)=length x width
we suggest this system of equations:
y=x/5
xy=9/20
solve this system of equations by substitution method:
x(x/5)=9/20
x²/5=9/20
Least common multiple=20
4x²=9
x²=9/4
x=⁺₋√(9/4)
we have two solutions:
x₁=-3/2 it does not validate
x₂=3/2 ⇒y=x/5=(3/2)/5=3/10
The dimensions of the lake are:
lengh=3/2 miles
width=3/10 miles
to check:
Area=3/2 miles x 3/10 miles=9/20 miles².
width is 1/5 the length of the lake ⇒ 3/10 miles=(3/2) /5 miles
