Answer:
The answer is
<h2>1.46</h2>
Step-by-step explanation:
Take logarithm of both sides of the equation
That's
Using the rules of logarithms
So we have
Divide both sides by log 3
We have
We have the final answer as
1.46497
which is
1.46 to 2 decimal places
Hope this helps you
Answer:
a = 2 ; b = -3 ; c = -20
Step-by- step explanation:
Use FOIL method.
(2x + 5)(x - 4) = 0
2x*x+ 2x*(-4 )+ 5*x + 5* (-4) = 0
2x² - 8x + 5x - 20 =0
Combine like terms,
2x² - 3x - 20 = 0
Standard form: ax² + bx + x = 0
a = 2
b = -3
c = -20
Answer:
Step-by-step explanation:
The circular city park has a sidewalk directly through the middle that is 111 - feet long. This means that the diameter of the park is 111 feet.
The formula for determining the the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circular floor.
π is a constant whose value is 3.14
From the information given,
Diameter = 111 feet
Radius = diameter/2 = 111/2 = 55.5 feet.
Area of park = 3.14 × 55.5² = 9671.985 feet²
If each bag of fertilizer covers 50 square feet, then the number of bags needed is
9671.985/50 = 193.44 bags
15*4= 60 (60 students in total)
180/60= 3 (180 book covers divided among 60 students)
Each student gets 3 covers.<span />
Answer:
c)-4/3
Step-by-step explanation:
perpendicular slope is opposite and reciprocal
the green line has a slope of 3/4
so the slope of the red line is -4/3
