A block of wood has the shape of a triangular prism. The bases are right triangles. Find its surface area.
Answers
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

A dog walked 25 miles in 12.5 hours. Find the speed of the dog.
Answers
Answer:
Step-by-step explanation:
Someone calculated his or her average speed to 18.36 Miles per hour (mph) Calculate your average speed This calculation will help you calculate your average speed when you have covered a certain distance over a certain time.
Answer:
2 mph
Step-by-step explanation:
if we divide our miles by our time with the equation d for distance and t for time we'll get this
d/t = s (s to represent the speed
now time to plug in our equation
25/12.5 = 2
we now have our answer of 2 miles per hour
A swimmming pool with cylindrical base has a diameter of 21 feet and a depth of 5 feet. Find the volume of the pool
Answers
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.

17. Find the value of x. Round to the nearest degree.
Answers
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.

Angle P is intercepted by two arcs.
SB and RQ.
We can use this theorem,
If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.
So in other words,

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
Answers
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

A submarine 58 feet below see level. An a airplane is 264 feet above sea level. How far above is the submarine in the plane?
Answers
Answer:
322
Step-by-step explanation:
58+264=322
Answer:
322 feet
Step-by-step explanation:
if the question was two positive heights, you would subtract, and you still do. we find how many inches my father is taller than me by subtracting my height from his, and the same applies to this, though the submarine, being below sea level is at a negative height. when you subtract a negative, it's the same as adding a positive.
264 - (-58)
264 + 58 = 322
