Which set of shapes could you use to form a net for a
triangular prism?
O 5 triangles
О 4 triangles, 1 rectangle
O 3 triangles, 2 rectangles
O 2 triangles, 3 rectangles
find the total surface area of the prism. geometry hw. plz help me
Answer:
152
Step-by-step explanation:
Hello there!
The prism shown is a triangular prism
There are many different formulas for solving for the surface area of a triangular prism but I am going to use the most simple one
Formula: SA = bh + L(s1 + s2 + s3) (found in the image)
b = base length
h = height
L = length
s1 = (same thing as the base length)
s2 and s2 = other triangle side lengths ( the base is an isosceles triangle so they are equal to each other.)
The triangular prism has the following dimensions
b = 6
h = 4
L = 8
s2 and s3 = 5
Now that we have identified each dimension we plug in the values into the formula
SA = 6*4 + 8(6+5+5)
6*4=24
8*6=48
8*5=40
40*2=80
80+48=128
128 + 24 = 152 so the surface area of the triangular prism is 152 cm²

These are all Law of Cosine problems. A generic expression for the length of side 'c' opposite angle C, which is defined by sides 'a' and 'b' is ...
c² = a² +b² -2ab·cos(C)
The square root of this gives the side length:
c = √(a² +b² -2ab·cos(C))
Rearranging the equation, we can obtain an expression for the angle C.
C = arccos((a² +b² -c²)/(2ab))
These two formulas are used to solve the offered problems.
__
1) AC = √(13² +14² -2·13·14·cos(109°)) ≈ √483.506
AC ≈ 22.0
__
2) BC = √(7² +10² -2·7·10·cos(123°)) ≈ √225.249
BC ≈ 15.0
__
3) ∠B = arccos((24² +28² -14²)/(2·24·28)) = arccos(1164/1344)
∠B ≈ 30.0°
__
4) ∠B = arccos((6² +9² -14²)/(2·6·9)) = arccos(-79/108)
∠B ≈ 137.0°

A is wrong because radians really refers to the arc with respect to the angle. The opposite is true with A.
D is wrong because the arc is actually bigger than the radius given 1.5 radians.
E is wrong because the area of the whole circle is defined as 2π radians, 1.5 rad × 1.5 = 2.25 rad is (405/π)° and 2π radians is 360° (2π × 180 / π)°.
F is wrong because the circumference of a circle is 2πr.

A trash can is in the shape of a cylinder. It has a radius of 2 feet and a height of 5 feet. What is the volume of the trash can? Round to the nearest tenth. Use 3.14 for π or pi.
Answer:
62.8 cubic feet
Step-by-step explanation:
V = πr^2h
r is radius
h is height
Radius = 2ft
Height = 5ft
V = (3.14)(2)^2(5)
V = 62.8 cubic feet
Solve the equation used to find the area of trapezoid for h A=1/2h(x+y)
How much more popcorn does the bigger box hold than the smaller box? cm^3
9514 1404 393
Answer:
70 cm³
Step-by-step explanation:
Amanda's container holds ...
V = LWH = (10 cm)(10 cm)(13.5 cm) = 1350 cm³
Mary's container holds ...
(8 cm)(8 cm)(20 cm) = 1280 cm³
The larger box holds 1350 -1280 = 70 cm³ more popcorn.

The following is a list of a student's scores on his Spanish test. 71,69, 65, 84, 82, 95 Which box plot represents this data?
The box which represents this data is Minimum: 65
Q1: 69
Median: 82
Q3: 110
Maximum: 95
We are given that;
71,69, 65, 84, 82, 95
Now,
A box plot is a type of chart that shows the five-number summary of a set of data: the minimum, first quartile, median, third quartile, and maximum. To make a box plot, you need to follow these steps 1:
Arrange the data from smallest to largest.
Find the minimum and maximum of the data. These will be the endpoints of the whiskers.
Find the median of the data. This will be the vertical line inside the box.
Find the first quartile (Q1) and the third quartile (Q3) of the data. These will be the lower and upper edges of the box.
Find the interquartile range (IQR) by subtracting Q1 from Q3. This is the length of the box.
Find the lower and upper limits by subtracting 1.5 times IQR from Q1 and adding 1.5 times IQR to Q3. These are the boundaries for detecting outliers.
Draw a box from Q1 to Q3 with a vertical line at the median. Draw whiskers from the box to the minimum and maximum values that are within the lower and upper limits. Mark any outliers with dots or asterisks.
Therefore, by algebra the answer will be
Minimum: 65
Q1: 69
Median: 82
Q3: 110
Maximum: 95

How long was the movie?
The movie was
hour(s) and
minutes.
Amar got home 45 minutes after the movie ended.
What time did Amar get home?
Complete the explanation for how you found your answer.
You need to find
minutes after 5:30 P.M.
5:30 to 6:00 is
minutes, so 15 minutes more is
:15.
Answer: the movie was 1 hour and 35 minutes and Amar got home at 6:15 P.M.
Step-by-step explanation:
to find out how long the movie was you have to find the distance between the time frames 3:55 and 5:30.
3:55+1 hour= 4:55
4:55+5 minutes= 5:00
5:00+30 minutes= 5:30
Add the times to find how long the movie was.
This is how I found how long the movie was.
To find out when Amar got home you have to do the same thing as well.
5:30+30 minutes= 6:00
6:00+15 minutes= 6:15
