Janine inflated a ball to a radius of 18 cm and another ball to a radius of 12 cm. How much greater was the volume of air in the larger ball than the smaller ball? Use 3. 14 to approximate pi. Round to the nearest hundredth if necessary. Enter your answer as a decimal in the box. Cm³.
Answer:
Difference of volume of air = [tex]17182.08cm^{3}[/tex]
Step-by-step explanation:
Radius of ball = 18 cm
Volume of big ball = [tex]\frac{3}{4} \pi o^{3}[/tex]
= 4/3 x * 14 X 18[tex]^{3}[/tex]
= 7324g * g2/ 3
= 24416.64cm^3
Radious of another (small ball) = 12 cm
Volume of small ball = [tex]\frac{3}{4} \pi R^{3}[/tex]
= 4/3 x 3 * 14 X 12^3
= 21703.68/ 3
= 7234 * 56cm^3
Difference of volume = [tex]v_{b} -v _{s}[/tex]
= 24416 * 64 - 7234 * 56cm^3
= 17182 * 08 cm^3

Given an equilateral triangle with sides of length 9, find the length of the altitude. Confirm your answer using the
Pythagorean theorem.
Applying the Pythagorean theorem, the length of the altitude is: 7.79 units.
What is the Pythagorean Theorem?The Pythagorean Theorem is given as: c² = b² + a², where c is the hypotenuse.
An altitude of an equilateral triangle bisects the base of the triangle forming equal segments. Therefore, we would have the following:
c = 9
b = 4.5
Length of altitude = a = ?
Thus:
a = √(c² - b²)
a = √(9² - 4.5²)
a = 7.79 units.
Thus, applying the Pythagorean theorem, the length of the altitude is: 7.79 units.

What is the value of X
Answer:
x = 4[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2x = 8[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
x = 4[tex]\sqrt{3}[/tex]
Determine the measure of each angle using the picture below. Assume the two lines are parallel.
Answer:
Step-by-step explanation:
Angle 5 is opposite to 37 => It's equal to 37.
Angle 6 and 7 are supplementary to angle 5 => They are equal to 180 - 37 = 143 each.
Angle 4 is corresponding to Angle 7, and since the 2 lines are parallel, it's equal to 143.
Angle 1 and 3 is supplementary to Angle 4, so they are equal to 180-143 = 37 each
Angle 2 is opposite to Angle 4, so it's equal to 143.
Answer : Angle 1,3,5 = 37
Angle 2,4,6,7 = 143

Say you wanted to give someone 35000 berries, but every time you give someone berries, it takes away 30%. How could you calculate the exact amount of berries you would need to give someone 35000 berries.
Answer:
What I understand is that I need to give someone an exact number so that when 30% is taken, they keep exactly 35,000
To make the statement above true, we would need to divide 35,000 by 7 since the answer would be 10% of the number we need. Once we do this we get 5000 which is 10% now we multiply 5000 by 10 to get 100% and we get 50.000 once we give this amount to the person and 30% is taken away they are left with 35,000

This budget can be modified by increasing the amount spent on food and utilities and decreasing the amount spent on clothes and rent, thereby maintaining a positive actual net income.
b.
This budget can be modified by reducing the amount spent on rent and utilities, thereby reducing overall expenses to have the maximum amount of money for all other expenses.
c.
This budget can be modified by reducing the amount spent on food and clothes, thereby reducing overall expenses to have the maximum amount of money for fixed expenses and maintaining a positive actual net income.
d.
This budget cannot be modified.
To give a positive actual net income, the budget can be modified by reducing the amount spent on food and clothes, thereby reducing overall expenses to have the maximum amount of money for fixed expenses.
Option C is correct.
What is an actual net income?In accounting, the actual net income is defined as an entity's income minus the costs of expenses on goods sold, depreciation, amortization, interest, and taxes.
To determine actual net income, start with gross income, which is the whole amount of money earned, and then deduct costs like taxes and interest payments.

what distance did Maya travel if she ran for t hours and then biked for r hours?
The distance Maya traveled is (6t + 9r) miles
Speed, distance and timeFrom the question, we are to determine the distance Maya traveled
First, we will determine the speed at which she runs and the speed at which she bikes
Using the formula,
[tex]Speed = \frac{Distance}{Time}[/tex]
Running
Distance = 18 miles
Time = 3 hours
Then,
Speed = [tex]\frac{18}{3}[/tex]
Speed = 6 miles/hour
BikingDistance = 18 miles
Time = 2 hours
Then,
Speed = [tex]\frac{18}{2}[/tex]
Speed = 9 miles/hour
Now, for the distance she ran for t hours
From
Distance = Speed × Time
Distance = 6 × t
Distance = 6t miles
For the distance she bikes for r hours
Distance = 9 × r
Distance = 9r miles
Total distance traveled = 6t + 9r miles
Hence, the distance Maya traveled is (6t + 9r) miles

A plain pizza cost $8.35. Additional toppings cost $0.95 each. Which equation can be used to represent the cost of a pizza, y, with x toppings?
Answer: y=0.95x+8.35
Step-by-step explanation: Hi there.
We can use the equation y=mx+b, where
y=the result (in this case the cost of the pizza)
m=the slope (how much each topping costs)
x=input value (how many kinds of toppings the pizza has)
b=initial value (how much the plain pizza costs)
The toppings cost $0.95, and the value of the plain pizza is $8.35
So the equation is: y=0.95x+8.35.
