Answer:
40 pencil cases
Step-by-step explanation:
To find out how many $2.50 pencil cases you can buy with $100, you need to divide. Dividing the amount of money you have by the cost of the item will get you the amount of items you can buy. 100 divided by 2.50 is 40. So, you can get 40 cases.
Cylinder A has a base of 3 and height of 3 cylinder be has the base of 2 and the height of 4. What is the ratio of the volume of cylinder A to the volume of cylinder B?
Answer:
1.6875
Step-by-step explanation:
For cylinder A, the base = diameter = 3, the height of the base is 3.
The radius of cylinder A (r) = diameter / 2 = 3/2 = 1.5
The volume of a cylinder is given by the equation:
Volume (v) = πr²h
Therefore volume of cylinder A = πr²h = π × 1.5² × 3 = 6.75π
For cylinder B, the base = diameter = 2, the height of the base is 4.
The radius of cylinder B (r) = diameter / 2 = 2/2 = 1
The volume of a cylinder is given by the equation:
Volume (v) = πr²h
Therefore volume of cylinder A = πr²h = π × 1² × 4 = 4π
The ratio of the volume of cylinder A to the volume of cylinder B = volume of cylinder A / volume of cylinder B = 6.75π / 4π = 1.6875

Complete question:
A veterinarian surveys her clients and finds that 32 percent of the households have dogs, 25 percent have cats, and 11 percent have both dogs and cats. Let event C be choosing a client who has cats and let event D be choosing a client who has dogs. Which statements are true? Check all that apply.
1. P(C | D) = 0.78
2. P(D | C) = 0.44
3. P(C ∩ D) = 0.11
4. P(C ∩ D) = P(D ∩ C)
5. P(C | D) = P(D | C)
Answer:
3. P(C ∩ D) = 0.11
4. P(C ∩ D) = P(D ∩ C)
Step-by-step explanation:
Clients that have Cats = P(C) = 25% = 0.25
Clients that have Dogs = P(D) = 32% = 0.32
The number of Clients that have Dogs and Cats = P(D ∩ C) = 11% = 0.11
Sets of data in mathematics are governed by laws which include Distributive law, Commutative law, Associative law, Identity law e.t.c.
The commutative law of sets states that :
A ∩ B = B ∩ A
A ∪ B = B ∪ A
Therefore, based on the commutative law of sets, Option 4 " P(C ∩ D) = P(D ∩ C) " is correct.
Since we are told in the question above that the number of Clients that have Dogs and Cats = P(D ∩ C) = 11% = 0.11 and based on the commutative law that says
P(C ∩ D) = P(D ∩ C)
Therefore, Option 3 " P(C ∩ D) = 0.11"
is correct as well.

Describe the transformations from, y=x2, the original parent function
y = (x - 6)2
Going from y = x^2 to y = (x-6)^2 has the graph shifted 6 units to the right
The replacement of "x" with "x-6" shifts the xy axis 6 units to the left. All new inputs are 6 units smaller than before. If you shift the xy axis 6 units to the left and keep the parabola still, then it gives the illusion the parabola moved 6 units to the right.

Judith scores an 85 on 19 of the 25 math tests she took this year. What is the experimental probability that she will score an 85 or higher on her next test? Write the probability as a percent.
Answer:
The answer is %33,33.
Step-by-step explanation:
Depending on the information given in the question, we can see that Judith received a score of 85 or higher in one of her three tests.
So we can calculate her probability of receiving 85 or higher as 100/3 = %33,33.

The radius of a circle is 1 foot. What is the diameter?
r=1 ft
Give the exact answer in simplest form.
feet
Final answer:
The diameter of a circle with a radius of 1 foot is 2 feet.
Explanation:
The radius of a circle is half the diameter. So, if the radius (r) of a circle is given as 1 foot, the diameter (d) is simply twice the radius. Therefore, the diameter is:
d = 2 × r
d = 2 × 1 ft
d = 2 ft
Hence, the diameter of the circle is 2 feet.

For a bookcase, Tim wants 6 shelves
each 28 1/2 inches long. What total length
of shelving does he need?
Answer:
171 inches
Step-by-step explanation:
6x28.5
The total length of shelving Tim needs for his bookcase is calculated by multiplying the number of shelves (6) by the length of each shelf (28 1/2 inches), which equals to 342 inches in total.
Explanation:When understanding the total length of shelving needed, you can use the basic principle of multiplication in mathematics. In this particular question: bookcase shelving length, Tim wants to build a bookcase with 6 shelves and each shelf is 28 1/2 inches long. You would calculate the total length by simply multiplying the number of shelves by the length of each shelf.
So, 6 shelves * 28 1/2 inches = 57 * 6 = 342 inches. Hence, the total length of shelving Tim needs for his bookcase is 342 inches.

Cylinder r=3 H=16
cone d=6 H=9
Answer:
C = 144*pi cubic units (cylinder)
V = 27*pi cubic units (cone)
Step-by-step explanation:
Cylinder r=3 H=16
cone d=6 H=9
I know what you mean.
You want volume.
C = (pi)*r^2 * h
V = (1/3)*(pi) *r^2 * h for a cone
---------------------------
C = (pi) * (3)^2 * 16 = 144*pi cubic units (cylinder)
V = (1/3)*(pi)*(3^2) * 9 = 27*pi cubic units (cone)
Write the equation x2=7x in standard form.
Answer:
i believe it's x2-7x=0
Step-by-step explanation:
To write the equation x^2 = 7x in standard form, subtract 7x from both sides and rearrange the terms in descending order of exponents.
Explanation:The equation x^2 = 7x is a quadratic equation. To write it in standard form, we need to move all the terms to one side and set the equation equal to zero.
Subtracting 7x from both sides, we get x^2 - 7x = 0.
Next, we rearrange the terms in descending order of exponents: x^2 - 7x = 0.

A rectangular gardens length is 6 feet longer than it’s width. if the perimeter can be represented by P(x)= 4x + 12.
What is the width and length of the garden if the perimeter is 32 ft?
Answer:
The width is 5 and the length is 11
Step-by-step explanation:
The formula for perimeter is
P = 2(l+w)
We know the perimeter is 32
32 = 2 (l+w)
Divide each side by 2
32/2 = 2(l+w)
16 = l+w
We know the length is 6 longer than the width
l = w+6
16 = w+6+w
Combine like terms
16 = 2w+6
Subtract 6 from each side
16-6 = 2w+6-6
10 = 2w
Divide by 2
10/2 = 2w/2
5 =w
The length is
l = w+6
5+6 = 11

Which statement is correct about the system of linear equations graphed below? On a coordinate plane, a line with negative slope goes through (0, 3) and (4, 2). A line with positive slope goes through (0, negative 4) and (4, negative 2). The system of equations has one solution because the lines will eventually intersect. The system of equations has one solution because the lines will never intersect. The system of equations does not have one solution because the lines will eventually intersect. The system of equations does not have one solution because the lines will never intersect.
Answer:
the answer is A. The system of equations has one solution because the lines will eventually intersect
Step-by-step explanation: because as the line goes on it will intercect once and if it has only one point of intercect its one solution
The system of equations has one solution because the lines will eventually intersect.
Which statement is true?
We know that for a system of equations, the solutions are the points where the graphs of the equations do intercept.
Also, remember that two lines always intercept if they have different slopes (parallel lines have the same slope and different y-intercept).
In this particular case, we know that one line has a negative slope and the other has a positive slope, so the lines are not parallel. This means that the lines will intercept, so the system has one solution.
With that in mind, the correct statement is "The system of equations has one solution because the lines will eventually intersect."
