Answer:
8
Step-by-step explanation:
E = 15, V = 9, F =?
By Euler's rule, we have:
F + V - E = 2
F + 9 - 15 = 2
F - 6 = 2
F = 6 + 2
F = 8

A block of wood has the shape of a triangular prism. The bases are right triangles. Find its surface area.
Answer:
Step-by-step explanation:
Area Triangles
Area = 1/2 b * h
In a right triangle the two smaller sides are used to find the area
A = 1/2 6 * 4.5
A = 1/2 * 27
A = 13.5
But there are 2 of them so that the area = 2* 13.5 = 27
Area Front side
Area = L * w
L = 13
w = 6
Area = 13 * 6
Area = 78
Area Back side
Area = L * W
Area = 4.5 * 13
Area = 58.5
Bottom Area
Area = L * W
L = 13
W = 7.5
Area = 13 * 7.5
Area = 97.5
Total Area = 58.5 + 78 + 27 + 97.5
Total Area = 163.5 + 97.5
Total Area = 261
17. Find the value of x. Round to the nearest degree.
Answer:
51. Don't completely know if it's correct though.
Step-by-step explanation:
I'd use sine, which is opposite side/hypotenuse. Here, I think the reference angle is x. The opposite side is 7, and the hypotenuse is 9. So...
sin(x) = [tex]\frac{7}{9}[/tex]
sin(x) = 0.7777
Next we use inverse sine.
sin⁻¹(0.7777) = approximately 51
The value of the angle x, for the given right angle, is approximately 51 degree to the nearest degree.
What is right angle triangle property?In a right angle triangle, the ratio of the opposite side to the hypotenuse side is equal to the sine angle between adjacent side and hypotenuse, side.
[tex]\sin\theta=\dfrac{b}{c}[/tex]
Here, (b) is the opposite side, (c) is the hypotenuse side and [tex]\theta[/tex] is the angle made between adjacent side and hypotenuse, side.
In the given figure, the hypotenuse side is 9 units long and opposite side is 7 units long.
The angle between adjacent side and hypotenuse is x degrees. Thus, by the right angle triangle property,
[tex]\sin x=\dfrac{7}{9}\\x=\sin^{-1}(0.778)\\x\approx51^o[/tex]
Hence, the value of the angle x, for the given right angle, is approximately 51 degree to the nearest degree.

Answer: What is the question?
Step-by-step explanation:
Two solids are described in the list below.
• One solid is a sphere and has a radius of 6 inches.
• The other solid is a cylinder with a radius of 6 inches and a height of 6 inches. What is the difference between the volumes, in cubic inches, of the solids in terms of pi?
A) 72pi
B) 144pi
C) 216pi
D) 288pi
Answer:216X
Step-by-step explanation:
Volume of the sphere = 4/3 πr³
radius r = 6 inches
Volume = 4/3 π(6)³
⇒ 4/3(216)π
⇒ 472π
⇒ 288π cubic inches
Volume of a cylinder = π r²h
radius r = 6 inches
height h = 6 inches
Volume = π(6)²(6)
⇒ 6³π
⇒ 216π cubic inches
Difference between the volumes = 288π - 216π = 72π

Shrek, Donkey, and Fiona are riding in a carriage to Far Far Away. The horses, Prescott and Thaddeus, are pulling the carriage all the way. Prescott alone could pull the carriage all the way to Far Far Away and back to The Swamp in 21 days, but together they are able to pull the carriage to Far Far Away in 9 days.
Answer:
Step-by-step explanation:
Remark
I suppose the question is what is Thaddeus' time to make the trip. This is a fairly common question but not everyone knows how to solve it.
Derivation of the Formula
Prescott + Thaddeus = 1 trip
So the logic of the equation is this.
distance = 1 trip
time = number of dates
rate = ?
rate = distance / time
To find out what the contribution of Thaddeus is set up a distance time formula.
1/21 days is the rate for Prescott
1/x days is the rate for Thaddeus
Together the rate is 1/9
Solution
1/21 + 1/x = 1/9
Subtract 1/21 from both sides
1/x = 1/9 - 1/21
It's not obvious what the LCM is.
9 = 3 * 3
21 = 3 * 7
LCM: 7 * 3 *3 = 63
1/x = 7/63 - 3/63 = 4/63
1/x = 4/63 Cross Multiply
4x = 63 Divide by 4
x = 63/4
Answer
x = 15 3/4
x = 15.75

A swimmming pool with cylindrical base has a diameter of 21 feet and a depth of 5 feet. Find the volume of the pool
Answer: V = 1731.8Ft³
Step-by-step explanation:
v = πr²h
Radius is half of the diameter ⇒ 21/2 = 10.5
V = π(10.5)²(5)
V=π(110.5)(5)
V = π(551.25)
V = 1731.8Ft³
The solution is : the volume of the pool is V = 1731.8Ft³.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
Here, we have,
we know that,
the volume of the cylinder is:
v = πr²h
Radius is half of the diameter
⇒ 21/2
= 10.5
so, we get,
V = π(10.5)²(5)
V=π(110.5)(5)
V = π(551.25)
V = 1731.8Ft³
Hence, The solution is : the volume of the pool is V = 1731.8Ft³.
