Find the volume of a cylinder with a radius of 3cm and a height of 7 cm.
Answer:
The volume of the cylinder ≅ 197.82[tex]cm^{2}[/tex]
Step-by-step explanation:
The volume of a cylinder is equal to the area of the base times the height. We know the radius, therefore we can find the area of the base. The formula for the volume of the cylinder is as follows:
V = π[tex]r^{2}[/tex][tex]h[/tex]
(now substitute the values of "r" and "h", and get...)
V = π[tex]r^{2}[/tex][tex]h[/tex]
[tex]V = (3^{2} )(7)[/tex] x π
V = (9)(7)π
V = 63π
V ≅ 197.82[tex]cm^{2}[/tex]
Find x and y in the given figure
Answer:
x= 70°, y=40°
Step-by-step explanation:
2x=140
x= 70
y= 180-140= 40
140 + y = 180
y = 180 - 140
y = 40
2x + 40 = 180 (Angle Sum Property)
2x = 180 - 40
2x = 140
x = 140/2
x = 70
X = 70
Y = 40

Answer:
56.52 units³
Step-by-step explanation:
[tex]v = \pi {r}^{2}h[/tex]
r = 3 units ; h (height) = 2
V = 3.14 × 3² × 2
= 3.14 × 9 × 2
= 56.52 units³
A farmer grows x acres of peas and y acres of tomatoes. He has 12 acres available to plant peas and tomatoes. Write an inequality in x and y to satisfy this condition. The number acres of tomatoes planted must not be more then twice the number of acres of peas planted. Write an inequality in x and y to satisfy this condition.
Answer:
Y < 2X
Step-by-step explanation:
Let the acres of land on which pea is to be cultivated is "X" acres and the acres of land on which tomato is to be cultivated is "Y"
It is given that number acres of tomatoes planted must not be more then twice the number of acres of peas planted
Thus, [tex]Y < 2X[/tex]
[tex]X + Y = 12[/tex] acres
[tex]Y = 12-X[/tex] acres
Thus,
[tex]12 - X \leq X\\12\leq 2X\\6 \leq X[/tex]
Let us take X = 6 , Then Y = 13-6 = 6

A triangle has two angle measures of 20 degrees and 30 degrees. Find the third angle. This triangle is a(n) ________ triangle
Question 2 options:
A. acute
B. obtuse
C. right
D. it does not make a triangle
Answer:
Obtuse
Step-by-step explanation:
x = missing angle
20+30+x=180
50+x=180
x=130
90<130
Thus, the triangle is obtuse

Graph this: y = 2sIn(x) - 3
Insert picture of graph
Answer:
We have the function:
f(x) = 2*sin(x) - 3
To graph this type of functions is useful to understand the parts of the function.
A general one is written as:
g(x) = A*sin(w*x + p) + M
where:
A is the amplitude
w is the angular frequency.
p is the phase
M is the midline.
Then in this case we have an amplitude of 2, an angular frequency of 1, a phase of 0 radians and the midline y = -3
Now we can evaluate the function in different points and (knowing how a sine function behaves) connect them, the graph will look something like this:

Answer:
1. 24/40, 32/40, 24/32 (This is in order from top to bottom)
2. 21.1
3. 4.1
Step-by-step explanation:
1. Here, we only have to focus on Angle X.
Let's label in the sides:
Opposite = YZ = 24
Adjacent = XY = 32
Hypotenuse = XZ = 40
SOHCAHTOA simply means: You can memorise this through the acrostic poem of - Slap On Head Causes A Headache Take One Aspirin, but I remember it by Suck A Toe because that's what it sounds like.
Sin(x) = Opposite/Hypotenuse
Cos(x) = Adjacent/Hypotenuse
Tan(x) = Opposite/Adjacent
Sin(X) = 24/40
Cos(X) = 32/40
Tan(X) = 24/32
The question only asks to give the ratios by using / for a fraction, so we don't simplify it.
2. We are given the angle of 64°, the opposite length 19 and we have to work out x, which is the hypotenuse. We can use the sin function as we have our opposite length and we have to work out the hypotenuse.
Sin(64) = 19/x
xSin(64) = 19
x = 19/Sin(64)
x = 21.13943687
x = 21.1
3. We are given the angle of 70°, the hypotenuse 12 and we have to work out x, which is the adjacent side. We can use the cos function as we have to work out the adjacent side and we have our hypotenuse given to us.
Cos(70) = x/12
12Cos(70) = x All we have to do here is multiply by 12!
x = 4.10424172
x = 4.1

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $7500 to rent trucks plus an additional fee of $150.25 for each ton of sugar. The second company charges $7143 to rent trucks plus an additional fee of $175.75 for each ton of sugar.
Answer:
14 tons of sugar
$9603.5
Step-by-step explanation:
For what amount of sugar do the two companies charge the same?
What is the cost when the two companies charge the same?
Let
x = ton of sugar
Company A:
7500 + 150.25x
Company B:
7143 + 175.75x
1. Equate company A and company B
7500 + 150.25x = 7143 + 175.75x
7500 - 7143 = 175.75x - 150.25x
357 = 25.50x
x = 357/25.50
x = 14 tons of sugar
2. Cost when both companies charge the same
Company B:
7143 + 175.75x
= 7143 + 175.75(14)
= 7143 + 2460.5
= 9603.5
Company B = $9603.5
Company A:
7500 + 150.25x
= 7500 + 150.25(14)
= 7500 + 2103.5
= 9603.5
Company A = $9603.5
