Answer:
12 miles
Step-by-step explanation:
Your car uses 1/12th of its entire gas to go a single mile. This means that you need to drive 12 miles to run out of gas.
Answer:
Step-by-step explanation:
Given
The attached triangle
Required
Find x
Considering angle 30 degrees,
Using the tangent formula:
Make x the subject
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
Answer: x = 0
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Good morning
Answer:
B: (1, 5)
Step-by-step explanation:
This graph shows the solutions to the inequality: y > (1/3)x - 2
Since, 5 > (1/3)×1 - 2 then the point (1 ,5) is a solution to the inequality.
