A cone has a volume of 33 cubic inches. If a cylinder has the same height and the same radius as the cone, what is the volume of the cylinder?
Answer:
C
Step-by-step explanation:
Step-by-step explanation:
The volume of a cylinder = πr²h
= 33 cubic inches
The volume of a cone = ¹/3 πr²h
If the cylinder and come share the same radius and height then ‘πr²h’ part of the formulas is the same for both;
It means the difference in proportionality is ¹/3 (because even π is the same across board). The volume of the cone is therefore;
¹/3 (33)
= 11
= 11 cubic inches

Select the correct answer from the drop-down menu.
A whole number is 6 more than 2 times another number. The sum of the two numbers is less than 50. This can be written in an inequality as
x+2x+6 < 50, where x represents the smaller number.
From the set {13, 14, 15, 16, 17), the values of x for which the inequality holds true are
Reset
Next
Answer:
13 and 14
Step-by-step explanation:
From the inequality
x + 2 x + 6 < 50
we work out the answer for x isolating it on one side of the inequality as shown below
3 x + 6 < 50
3 x < 50 - 6
3 x < 44
x < 44/3 ≅ 14.6666...
Therefore, select from the set the numbers: 13 and 14.

Here is a balanced hanger.
1. Write an equation representing this hanger.
2. Find the weight of one circle. Show or explain how you found it.
25
Answer:
the weight of one circle is 6.25
Step-by-step explanation:
25 divided by 4=6.25
Check:
6.25x4=25
4w=25 is the equation which represents the hanger and weight of one circle is 6.25 units.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A hanger stays balanced when the weights on both sides are equal.
The hanger has four circles on left hand side and value 25 on the right hand side
By equating both we get
w+w+w+w=25
4w=25
4w=25 is an equation representing this hanger.
Now let us find the weight of one circle
Divide both sides by 4
w=25/4
w=6.25
Hence, 4w=25 is the equation which represents the hanger and weight of one circle is 6.25 units.

Christine has her own dog-walking business. She charges her customers $20 per day to walk their dog.
Make a table to show how much she earns for walking 1 to 8 dogs.
Please help me !
Answer:
Number of dogs (x) | Amount charged to walk a dog (y)
1 | 20
2 | 40
3 | 60
4 | 80
5 | 100
6 | 120
7 | 140
8 | 160
Step-by-step explanation:
Charge for walking a dog = $20 per dog
Number of dogs = x
Amount charged to walk a dog in a day = y
Unit rate = 20
Equation to represent this is: y = 20x
Let's use this to form a table for walking 1 to 8 dogs:
For 1 dog (x):
y = 20(1) = $20
For 2 dogs (x):
y = 20(2) = $40
For 3 dogs(x):
y = 20(3) = $60
For 4 dogs:
y = 20(4) = $80
And so on till we get to tl8 dogs.
This, we should have the following table:
Number of dogs (x) | Amount charged to walk a dog (y)
1 | 20
2 | 40
3 | 60
4 | 80
5 | 100
6 | 120
7 | 140
8 | 160
Please help this question finding a side on a triangle
Answer:
The side of the hypotenuse is 12.233 centimeters.
Step-by-step explanation:
The triangle presented in the figure represents a right triangle, we know an angle and a leg adjacent to such angle and we need to determine the length of the hypotenuse, which is found by this trigonometric relation:
[tex]\cos 56^{\circ} = \frac{7.4\,cm}{x}[/tex] (1)
Where [tex]x[/tex] is the length of the hypotenuse, measured in centimeters.
Then, we clear the variable within (1):
[tex]x = \frac{7.4\,cm}{\cos 56^{\circ}}[/tex]
[tex]x = 13.233\,cm[/tex]
The side of the hypotenuse is 12.233 centimeters.

The ratio of the measures of the sides of a triangle is 3:5:7, and its perimeter is 135 feet. Find the measure of each side of the triangle.
a. x = 9
b. 13.5 ft, 22.5 ft, 31.5 ft
c. 27 ft, 45 ft, 63 ft
d. 25 ft, 45 ft, 65 ft
Answer:
The correct answer is C. 27 ft, 45 ft, 63 ft.
Step-by-step explanation:
Given that the ratio of the measures of the sides of a triangle is 3: 5: 7, and its perimeter is 135 feet, in order to find the measure of each side of the triangle, the following calculation must be performed:
3 + 5 + 7 = 15
135/15 = 9
9 x 3 = 27
9 x 5 = 45
9 x 7 = 63
Therefore, the measures of the sides of the triangle are 27 ft, 45 ft, and 63 ft.

Below, enter x If the graph of the given equation is symmetric with respect to the x-axis, y if it is symmetric with respect to the y axis, o (lower
case O) if it is symmetric with respect to the origin, and n (for None) if it has none of these three symmetries.
y=xt
y = x2 +1
y=x²+x
y = (1 + x2)3
Answer:
Step-by-step explanation:
You can tell by looking at the form of each equation.
y = tx
This is a straight line that passes through the origin, so it symmetric with respect to the origin.
y = x²+1
This is an up-opening parabola with vertex at (0,1), so it is symmetrical about the y-axis.
y = x²+x = (x+½)² - ¼
This is an up-opening parabola with vertex at (-½,-¼). Not symmetrical to either axis nor to the origin.
Can't tell what "y = (1 + x2)3" means. Which terms are exponents?

A cookie recipe calls for 1.5 teaspoons of vanilla for one batch. How many teaspoons of vanilla would be needed for 2.5 batches of cookies?
Answer:
3.75
Step-by-step explanation:
it said 2.5 batches to you need to 1.5x2 = 3 15 divided by 2 = .75
3.75
3.75 teaspoons of vanilla will be needed for 2.5 batches of cookies. If it requires 1.5 teaspoons of vanilla for one batch.
The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
Given,
It requires 1.5 teaspoons of vanilla for one batch which can be interpreted as 1 batches of cookies requires 1.5 teaspoons of vanilla.
1 batches----->1.5 teaspoons of vanilla
Using unitary method,
To calculate the number of teaspoons of vanilla needed for 2.5 batch is as follows:
1 batches----->1.5 teaspoons of vanilla
Multiply 2.5 both sides.
(1 batches)X 2.5----->(1.5 teaspoons of vanilla)X 2.5
2.5 batches----->3.75 teaspoons of vanilla
3.75 teaspoons of vanilla will be needed for 2.5 batches of cookies
