Given:
The right triangular prism.
Height of prism = 28 in.
Hypotenuse of base = 25 in.
leg of base = 24 in.
To find:
The lateral surface area of the prism.
Solution:
Pythagoras theorem:
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
Using Pythagoras theorem in the base triangle, we get
[tex]25^2=24^2+Base^2[/tex]
[tex]625-576=Base^2[/tex]
[tex]\sqrt{49}=Base[/tex]
[tex]7=Base[/tex]
The perimeter of the triangular base is:
[tex]P=7+25+24[/tex]
[tex]P=56[/tex]
Lateral area of a triangular prism is:
[tex]A=Ph[/tex]
Where, P is the perimeter of the triangular base and h is the height of the prism.
Putting [tex]P=56,h=28[/tex] in the above formula, we get
[tex]A=56(28)[/tex]
[tex]A=1568[/tex]
Therefore, the lateral area of the prism is 1568 in².

Answer:
(a) 38.3 m horizontal distance
(b) 82.1 m high
Step-by-step explanation:
I like a graphical solution to this problem (attached).
__
If you define h as the horizontal distance to the tower, and t as its height, you can write two equations. Since these sides are adjacent and opposite the given angles, the tangent relationship is useful.
tan(65°) = t/h
tan(40°) = (t -50)/h
__
Multiplying both equations by h and substituting for t, we have ...
h·tan(40°) = h·tan(65°) -50
h = 50/(tan(65°) -tan(40°)) . . . . solve for h
h ≈ 38.3022
Then the tower height is ...
t = h·tan(65°) ≈ 82.1394
The tower is about 38.3 m distant and 82.1 m high.
Can anyone explain how to do this, please?

A computer chip company finds the experimental probability of manufacturing a defective computer chip is 1/3 how many defective computer chips are likely to be in a batch of 735 computer chips
Answers
Answer:
There are 245 expected defective chips in the batch
Step-by-step explanation:
From the question, we have that in a batch of computer chips, it is expected that a third is defective
Now, in this present batch, there are 735 chips
The number of defective chips is a third of this
Thus, we have the number of defective chips as;

It is 1/2 mile from a student's home to a store and back. In a week, she
walked to the store and back home 1 time. In the same week, she rode her
bike to the store and back 3 times. How many miles did she walk and ride
to the store and back in that week? *
Answers
Answer:
2 miles
Step-by-step explanation:
Given that :
Distance from home to store and back = 1/2 mile
In a week :
Number of times he walked from home to store and back = 1 time
Number of times she rode to store and back = 3 time
Note distance does not change whether she rode or walked:
Hence,
miles walked = 1/2 miles * 1 = 1/2 miles
Miles biked = 1/2 miles * 3 = 3/2 miles
Total Number of miles :
(1/2 + 3/2) = (1 + 3) /2 = 4/2 = 2 miles

you find what goes into that number
for example 6 goes into 18, 3 times
so you can keep the 6
next you put the x and plus stays the same
as we said before 6 goes into 18, 3 times so we put the 3 and y next
so this is the equation
6(x+3y)
6 times x = 6x
6 times 3 = 18
y and plus stay the same
brackets shows that your timesing the numbers

Answers
Answer:
3.75 cm³
Step-by-step explanation:
Each cube has equal sides of 1/2 cm
Length of the rectangular prism = 1/2 cm * 5
= 2.5 cm
Width of the rectangular prism = 1/2 cm * 2
= 1 cm
Height of the rectangular prism = 1/2 cm × 3
= 1.5 cm
Volume of the rectangular prism = length × width × height
= 2.5 cm * 1 cm * 1.5 cm
= 3.75 cm³

The population of a town was 25,000 in the 2000 census and 30,000 in the 2010 census. By what percent did the population increase?
Answers
Answer: This means that the population increased a 20% between the year 2000 and the year 2010.
Step-by-step explanation:
In this case, we have that 25,000 is the 100%.
Now we want to know which percentage represents 30,000
Let's suppose that the percentage is X.
Then we can have a system of equations:
30,000 = X
25,000 = 100%
To find the value of X, we can take the quotient of these two equations:
30,000/25,000 = X/100%
(30,00/25,000)*100% = X = 120%
Then in the 2000 we had a 100%, and in the 2010 there was a 120%.
The difference is:
120% - 100% = 20%
This means that the population increased a 20% between the year 2000 and the year 2010.
