How do I find the volume of a right triangular prism?

V = Base(the triangle parts) * height(the long side of the rectangles)
Now, the base of a triangle is 1/2*height(of the triangle)*edge(of triangle)
So:
V = 1/2 *a * c * h
Hope this helps!

What is the surface area of this right rectangular prIsm?
uranmaximum [27]

Answer:

28

Step-by-step explanation:

To find the area of a rectangle we multiply two edges together.

since we are looking for the surface area we are actually going to be finding 6 different areas and adding them together (since there are 6 sides to a rectangle)

ok so sides 1 and 2, the edges on the left and right will be equal, and then the four sides in the middle are all going to be equal

2(1x2) + 4(3x2) = 4 + 24 = 28

In figure qr = 1/3pr. find pq​
BaLLatris [955]

Answer:

PQ = 3.2

Step-by-step explanation:

QR =\frac{1}{3} PR

QR =\frac{1}{3} \times 4.8

QR =1.6

PQ = PR - QR

PQ = 4.8 - 1.6

PQ = 3.2

Riangle XYZ was dilated by a scale factor of 2 to create triangle ACB and sin ∠X = 5 over 5 and 59 hundredths.
DochEvi [55]

Answer:

Step-by-step explanation:

1. Part A: We know parts of our triangle since the cosine of X is given.  XY = 2.5 and XZ = 5.59 and since it is a scale factor of 2, ABC is most likely similar to XYZ by angle measures and the special relationship is, that they are all equal, because with a scale factor of two, all the ratios in triangle ABC will simplify to the ratios of triangle XYZ. 

Part B: Because triangle XYZ was dilated with a scale factor of 2 to create triangle ABC, just multiply the sides by 2 to get the sides AC and CB, which is AB = 2 times XY and CB = 2 times XZ. 

2. We can first find the hypothenuse by adding squaring 8 and 6 to have 100. Then square root it to have 10 as our hypothenuse

Now we can use sin x = 6/10 and cos y = 6/10

3. Since this is using the angle of elevation, we can say that the length of side AB is perpendicular from the perspective of angle of elevation, and the hypotenuse's length is known, so in this case, we can use a sine or cosecant ratio. 

Sin(40 Degrees) = AB/100

AB = 100 x sin(40 Degrees) ft

AB ~ 64.28 ft which can be rounded to 64 ft

The triangle I drew was a right triangle with points A, B, and C. 40 is on point C while 100 ft was on the hypotenuse. The kite was near A and the ground was between segment B and C.

4. Since the angle and Adjacent line is given and it is asking us to find H which is the opposite, we well try and be using Tangent = opposite/adjacent 

500 ft Multiply by tan39 = 405 (Estimated after rounding to nearest hundreth 404.892).

To be honest, I didn't know so much about these questions but this might give a better understanding and if I'm wrong then I apologize.

A coin is tossed and a spinner numbered 1 to 7 is spun. What is the probability of getting an odd number and heads
Vikki [24]
Your answer is 4/14 or 2/7. There are two possibilities when you flip a coin, heads or tails. Then for the spinner there are 7. Multiply them by each other to get the total number of outcomes of the situation of 14. Then there are only 4 odd numbers from 1-7. This means that you would only be able to get an odd number and heads 4 times.

Hope this helped!
