Answer:
89.14 in.³
Step-by-step explanation:
A semi-cylinder is half of a cylinder. A cube has equal sides. So if it is placed on top a cube, the following dimensions can be deduced:
The length of one side of the cube (s) = the diameter (d) of the semi-cylinder and also the height (h) of the semi-cylinder
Length of one side of the cube = 4 in.
Therefore,
Diameter of semi-cylinder = 4 in.
radius (r) = ½(4) = 2 in.
Height (h) of semi-cylinder = 4 in.
Let's find the volume of the composite solid
Volume of the composite solid = volume of semi-cylinder + volume of cube
= ½(π*r²*h) + (s³)
Volume of composite solid = ½(π*2²*4) + (4³)
= ½(50.27) + 64
= 89.135
≈ 89.14 in.³ (nearest hundredth)
Find the number of ways the digits 0,1,2 and 3 can be permuted to give rise to a number greater than 2000
Answer:
12
Step-by-step explanation:
You have to have the 2 or 3 as the first digit.
After that, the other 3 digits can be done in 3! = 6 ways.
So, the total is 2*3! = 12

Step-by-step explanation:
A cell phone company charges a flat rate of $2.50 per month, with an additional charge of $0.15 per minute. How many minutes did Laura talk on her cell phone if her monthly bill was $72.25?
Answer:
465 minutes
Step-by-step explanation:
First things first, you have to make an equation! It would be...
2.50+0.15m=72.25
Keep in mind that m stands for minutes.
Now let's solve it!!
First let's subtract 2.50 from both sides.
0.15m=69.75
Now, let's divide 0.15 on both sides!
m= 465
465 minutes!!
Hope this helped!! :D
What is the volume of a cylinder with a base radius of 7in. and a height of 12in?
Answer:
1847.26 cubic inches
Step-by-step explanation:
The volume of a cylinder is given by the formula:
V = Ah
Where V is the volume of the cylinder, A is the area of the base, and h is the height of the cylinder. The area of the base can be shown as the formula for the area of a circle:
A = πr²
Where r is the radius of the circle.
Now, find the area of the base of the cylinder:
A = π(7)²
A = 153.93804
Next, plug this value into the equation for volume, substituting h for the height of the cylinder; 12 inches.
V = 153.93804(12)
V = 1847.26
Volume is given in cubic units, and the units for this cylinder are inches, so this cylinder has the following volume:
1847.26 cubic inches

Vaughn is calculating the volume of the cylinder below using the following work.
51 cm
24 cm
V = 3.14(12)(5)
= 3.14(144) (5)
= 2,260.8 cm
What was Vaughn's first error?
He confused the height and the diameter.
He squared 12 instead of 24.
He applied the exponent before multiplying 12 and
5.
He used the wrong units in his final answer.
Answer:
He confused the height and diameter
Step-by-step explanation:
Given that,
The radius of the cylinder, r = 2.5 cm
Height of the cylinder, h = 24 cm
The volume of the cylinder is given by the formula as follows :
[tex]V=\pi r^2 h\\\\=3.14\times (2.5)^2\times 24\\\\=471\ cm^3[/tex]
Vaughn is confused in diameter and the height of the cylinder. He takes radius as 12 cm and height as 5 cm which is wrong. Hence, the correct option is (a).

Evaluate the expression 4.x2 + 3y for x = 5 and y=6.
Answer:Find an answer to your question Evaluate the expression 4x2+3y for x = 5 and y =6.
Solve the system of equations.
y = 2x
x + y = -6
Answer:
y=-4
x=-2
Step-by-step explanation:
Given:
x+y=-6
y=2x
So, you can then substitute y for 2x
x+(2x)=-6
Then, solve for x
3x=-6
x=-2
Then solve for y
y=2x=2(-2)=-4

Here is a linear equation: y = 1/4x +5/4
Are (1, 1.5) and (12, 4) solutions to the equation?
Yes or No?
PLEASE NEED HELP
Step-by-step explanation:
(1,1.5) is the solution but (12,4) is not the solution of given equation.
1.5=1/4×1+5/4(which is true)
4=1/4×12+5/4(which is false)
The point )1,1.5) is satisfying the equation y=(1/4)x + (5/4) and the point (12,4) is not satisfying.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Given points are (1, 1.5) and (12, 4). To check whether the points are the solution of the equation or not substitute the coordinates in the equation and check if LHS is equal to RHS then it is a solution otherwise not.
Check the point (1,1.5),
y=(1/4)x + (5/4)
4y = x + 5
(1.5)4 = 1 + 5
6 = 6
Check the point (12k,4),
y=(1/4)x + (5/4)
4y = x + 5
(4 x 4 ) = 12 + 5
16 ≠ 17
Therefore, the point )1,1.5) is satisfying the equation y=(1/4)x + (5/4) and the point (12,4) is not satisfying.

Identify the reference angle ∅ for each given angle, Ф.
When Ф = 300°, ∅=______degrees
When Ф = 225°, ∅=______ degrees
When Ф = 480°, ∅=______degrees
when Ф = -210°, ∅= ______ degrees
Answer:
See below for answers
Step-by-step explanation:
300° is in Quadrant IV, so its reference angle is 360°-300°=60°
225° is in Quadrant III, so its reference angle is 225°-180°=45°
480°=120° is in Quadrant II, so its reference angle is 180°-120°=60°
-210°=150° is in Quadrant II, so its reference angle is 180°-150°=30°
What is the distance between two points(2,-6)(-7,1)
Answer:
11.4
Step-by-step explanation:
Find the distance in the x-direction between the x-components: 2 - (-7) = 9.
Similarly: between the y-components: 1 - (-6) = 7
Apply the Pythagorean Theorem: 9^2 + 7^2 = d^2, where d is the desired distance:
81 + 49 = d^2, or d^2 = 130
The distance d is approximately √130 ≈ 11.4
Answer:
Square root of 130
Step-by-step explanation:
Use the distance formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]
[tex](x_{1}, y_{1} )[/tex] is your first set of coordinates : (2, -6)

find the total surface area of the prism 10 2 6
Answer:
88 units
Step-by-step explanation:
First, we need to find the surface area of each side of the prism. Assuming this is a rectangular prism, judging by the dimensions, that makes things easier.
10*2=20
We'll multiply 20 by 2 since there are 2 sides with these dimensions, resulting in 40 units.
2*6=12
We'll multiply that by 4 since there are 4 sides with these dimensions, resulting in 48 units.
Adding 48 to 40, we get 88.
Hope that helped.
