Answer:
3/4 of the area of the circle is of
squared units.
Step-by-step explanation:
Equation of a circle:
The equation of a circle has the following format:

In which the center is
and r is the radius.
Area of a circle:
The area of a circle of radius r is given by:

Circle (x+2)² + (y-5)² = 64
Comparing with the standard equation, we have that:

Area of the circle:

What is 3/4 of its area?

3/4 of the area of the circle is of
squared units.
Answer:
3.1 gallons
Step-by-step explanation:
To solve this, we need to figure out how many gallons of gas go into 72 miles. We know 23 miles is equal to one gallon of gas, and given that the ratio of miles to gas stays the same, we can say that
miles of gas / gallons = miles of gas / gallons
23 miles / 1 gallon = 72 miles / gallons needed to go to Bob's mother's house
If we write the gallons needed to go to Bob's mother's house as g, we can say
23 miles / 1 gallon = 72 miles/g
multiply both sides by 1 gallon to remove a denominator
23 miles = 72 miles * 1 gallon /g
multiply both sides by g to remove the other denominator
23 miles * g = 72 miles * 1 gallon
divide both sides by 23 miles to isolate the g
g = 72 miles * 1 gallon/23 miles
= 72 / 23 gallons
≈ 3.1 gallons
Answer:
<em>1796 students are boys.</em>
Step-by-step explanation:
If 5/9 of students are girls, then 4/9 of the students are boys.
4/9 * 4041 = 1796
Hey!
With the given information, we can form the equation y = 3x + 5, where y is the total and x is the number of miles.
IF the total amount was 29, we set y equal to 29.
29 = 3x + 5
subtract 5 from both sides
24 = 3x
divide both sides by 3
x = 8
Therefore he traveled 8 miles.
Step-by-step explanation:
<h3>f(x) = x² + 2x - 2</h3><h3>f(-2) = (-2)² + 2 (-2) - 2</h3><h3> = 4 - 4 - 2</h3><h3> = - 2</h3><h3 />
Hope it will help :)
