Find the volume of composite solid.
Answers
The volume of the given cylinder is 37.68ft³.
What is a cylinder?The three-dimensional shape of a cylinder is made up of two parallel circular bases connected by a curved surface. The right cylinder is created when the centers of the circular bases cross each other. The axis, which represents the height of the cylinder, is the line segment that connects the two centers. Real-world examples of cylinders include toilet paper rolls and cold beverage cans.So, according to the given image, the given solid is a cylinder.
The formula for the volume of cylinders is V = πr²hHeight is 3ft and D is 4ft so r will be 2 ft.Now, insert values in the formula as follows:
V = πr²hV = π2²3V = π4(3)V = 12πV = 37.68 (Let, π be 3.14)Therefore, the volume of the given cylinder is 37.68ft³.

Write down equation of lines l and m
Answers
Step-by-step explanation:
I assume you need the slope-intercept form
y = ax + b
"a" is the slope of the line, "b" is the y- intercept (the y-value when x = 0).
the slope is the ratio (y coordinate change / x coordinate change) when going from one point on the line to another.
for l we go from (5, 20) to (8, 80) and get
x changes by +3 (from 5 to 8)
y changes by +60 (from 20 to 80)
the slope is therefore
+60/+3 = 20/1 = 20 = a
so, we have
y = 20x + b
the y- intercept looks to be -80, but to be sure we use a point (e.g. 5, 20)
20 = 20×5 + b = 100 + b
b = -80
yes, the equation is
y = 20x - 80
for m we go from (5, 20) to (8, -40) and get
x changes by +3 (from 5 to 8)
y changes by -60 (from 20 to -40)
the slope is
-60/+3 = -20/1 = -20
we have therefore
y = -20x + b
we use the same trick for b as before
20 = -20×5 + b = -100 + b
b = 120
and our full equation is
y = -20x + 120

The individual can only fit 40 oz. of comics in a bag. If the individual brings 10 copies of the comic book he wants to sell (S), 4 copies to be appraised (A), the combined weight would be 30.2 oz. Calculate how much each comic (S) weighs.2.3 oz.2.25 oz.2.1 oz.
Answers
Let x represent the weight of the comic book to be sold
Let y represent the weight of the appraised book to be appraised
There are 15 copies of the comic book the individual wants to sell (S), and 8 copies of a comic book the individual wants appraised (A), with a combined weight of 49.9 oz. It means that
15x + 8y = 49.9 equation 1
If the individual brings 10 copies of the comic book he wants to sell (S), 4 copies to be appraised (A), the combined weight would be 30.2 oz, it means that
10x + 4y = 30.2 equation 2
Multiplying equation 2 by 2, it becomes
20x + 8y = 60.4 equation 3
Subtracting equation 3 from equation 1, it becomes
20x - 15x + 8y - 8y = 60.4 - 49.9
5x = 10.5
x = 10.5/5
x = 2.1
Substituting x = 2.1 into equation 2, it becomes
10(2.1) + 4y = 30.2
21 + 4y = 30.2
4y = 30.2 - 21 = 9.2
y = 9.2/4
y = 2.3
Weight of the comic(S) to be sold = 2.1 oz

The measure of the angle b is 61°.
In Euclidean geometry, an angle is a shape created by two rays that share a terminus and are referred to as the angle's sides and vertices, respectively. The plane that contains the rays contains the angles created by two beams.
Vertical Angles (Vertically Opposite Angles): The opposing angles created by the junction of two lines are known as vertical angles or vertically opposite angles. A pair of angles that are vertically opposed to one another are always equal.
The figure describes two angles 61° and b.
Now, from the figure the angles 61° and b are vertically opposite angles.
Therefore, the angles are equal.
b = 61°

You ask a deli clerk for x pounds of ham and x pounds of cheese. You end up getting 4 extra ounces of ham and
3 fewer ounces of cheese. The ham costs $6.24 per pound, and the cheese costs $4.80 per pound. You spend twice
as much on ham as you do on cheese. How much do you spend in total?
Answers
If the ham costs $6.24 per pound, and the cheese costs $4.80 per pound. You spend twice as much on ham as you do on cheese. The amount spent in total is: $187.20.
Total costLet number of ham bought = x + 4
Let number of cheese bought = x - 3
Price of ham = $6.24
Price of cheese = $4.80
Hence,
Amount spent on ham = (x+4)×6.24
Amount spent on ham =6.24x + 24.96
Amount spent on cheese = (x−3)×4.80
Amount spent on cheese =4.80x−14.40
So,
6.24 x + 24.96 = 2 (4.80 x - 14.40)
6.24x + 24.96 = 9.60 x - 28.80
Combine like terms
24.96 + 28.80 = 9.60 x - 6.24 x
3.36 x = 53.76
Divide both side by 3.36x
x = 53.76/3.36
= 16x
Now let find the total money spent where x is 16
Total amount = 6.24(16) + 24.96+ 4.80(16) - 14.40
Total amount = $187.20

plug in the intercepts which are 5 and 11 in this case
y=a(x-5)(x-11)
to solve for a, use the remaining point and set x to 6 and y to 5. we can do this because (6,5) is given to us as a solution of one of the points on the graph.
