a 24 foot tall streetlight casts a shadow that is 18 feet long. how long of a shadow is cast by a nearby parking meter post that is 4 feet high?
9514 1404 393
Answer:
3 ft
Step-by-step explanation:
The post is 4/24 = 1/6 as tall as the streetlight, so we expect its shadow to be 1/6 as long as that of the streetlight:
(1/6)(18 ft) = 3 ft
The parking meter post shadow is 3 feet long.
Alfred wants to become a member of an online discussion forum. The website requires him to create a password. The password must consist of 5 characters, of which 3 must be letters and 2 must be digits. The first character of the password must be a letter. Also, repetition of the same letter in the password is not permitted but repetition of digits is permitted. How many possible ways can Alfred create the password?
So I know the answer is 9,360,000 but I got 18,720,000. This is because I thought the partition is 4! / (2! * 1! * 1!) but apparently the partition is 4! / (2! * 2!) and this confuses me. I thought that since the letters can't be repeated, we'd put one unique letter in one group, the other unique letter in the other group, and the two repeated digits in the last group. Can somebody explain this to me?
Answer:
Alfred can create the password in 9,360,000 possible ways
Step-by-step explanation:
Given the data in the questions;
Password of five characters must contain; three letters and 2 digits
[][][][][]
Now, using the five boxes above which as to be filled with three letters and two digits, such that; The first character of the password must be a letter and repetition of the same letter in the password is not allowed while repetition of digits is allowed.
Now,
we know that there are 26 alphabets in English language, so the first box can be filled in 26 ways { must be a letter }
next four will be filed with two letters and two digits
so two boxes from the four can be chosen in the following ways;
⇒ ⁴C₂ = 4! / ( 2!(4-2)! = 24 / 4 = 6 { ways }
now for each choice, we can fill the chosen two boxes with letters in;
⇒ 25 × 24 = 600 { ways}
and the next two by digits; ( 0, 1, 2, ..... 9)
⇒ 10 × 10 = 100 { ways }
So in total, the possible number of ways he can create a password is;
⇒ 26 × 6 × 600 × 100
= 9,360,000 possible ways
Therefore, Alfred can create the password in 9,360,000 possible ways

Answer:
Length of pendulum = 72 feet
Step-by-step explanation:
Given:
Time period (T) = 9.42
pi = 3.14
According to question,
T = 2 x pi x root(L/32)
9.42 = 2 x 3.14 x root(L/32)
9.42 = 6.28 × root (L/32)
9.42/6.28 = root(L/32)
1.5 = root(L/32)
Squaring both sides,
2.25 = L/32
L = 2.25 x 32
L = 72
Answer:
L=72
Step-by-step explanation:
T=2pi[tex]\sqrt{L/32\\}[/tex]
9.42 = (2 x 3.14)[tex]\sqrt{L/32}[/tex]
1.5=[tex]\sqrt{L/32}[/tex]
2.25 = L/32 (I squared both sides)
L=72

I think yes but it could be no. Sorry if I am wrong but it should be yes.
please help!!!!!!!!!!!!!!!!!!!!
Answer:
I am not sure but think that the answer is 1/20
I believe you convert the whole number into a mixed fraction.
5 converted into quarters is 20/4. Then you divided 1/4 by 20/4.
1/4 divided by 20/4 is 1/20 or 0.05.
Please, don't refrain to tell me if this is incorrect. Thank you.
the measures of the angles of a triangle are shown below. find the measure of the smallest angle
Answer:
Step-by-step explanation:
44+9x+18+5x+20=180
14x+82=180
14x=180-82=98
x=98/14=7
other angles are
9x+18=9×7+18=81°
and 5x+20=5×7+20=55°
so angles are 44°,55°,81°
so smallest angle=44°

What is the sum of 4.5 x 10^3 and 2.5 x 10^2 ?
Answer:
4750
Step-by-step explanation:
you add the equation together and find the answer
Answer: 4500 and 250 = 4750
Step-by-step explanation: 10 to the power of 3 is 1000 because it’s 10x10x10 and if you multiply it by 4.5 it’s 4500 and then 10 times 10 is 100 times 2.5 is 250. And because we’re looking for the sum it wants the total so 4500 plus 250 is 4750

four conditions for a binomial experiment.
B. This is not a binomial experiment, because the trials are not
independent
C. This is not a binomial experiment, because each trial cannot be
classified as a success or failure.
D. This is not a binomial experiment, because the number of trials is
not fixed.

Please can someone help me !!
Answer:
Step-by-step explanation:
for question 4, the x= 116 °
they are just trying to show you that the degrees of the arc, is also the degrees of the angle from the center point of the circle.. and then they will get "tricky" with that idea :/
for question 5 x = 90 °
they just want you to recognize that a "tangent" line is 90 ° is all
for question 6 they want you to know this formula
(b -a) /2 where b = the bigger arc and a is the smaller arc
so (134 - 54) /2
80 / 2
40 °
the answer to 6 is 40 °

3/4 divided by 1/4 help can you teach me how to do it to
Answer:
3/4 divided by 1/4 = 3
Step-by-step explanation:
When we divide two fractions, such as 3/4 ÷ 1/4, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
We also simplify the answers to fraction problems whenever possible.
Answer:
3
Step-by-step explanation:
=(3/4)(4/1)
kcf (keep, change, flip)
so we're keeping 3/4 the same then we're changing it from division to multiplication and fliping 1/4 to 4/1 (as shown above)
3*4=12 and 4*1=4
so our new fraction is 12/4
12/4 is an improper fraction and 12 divided by 4 is 3
good luck :)
i hope this helps

4. A map has a scale factor of 1 cm = 15 miles
How far apart are two towns on the map if they are 100 miles apart in real life?
can anyone help please?
Answer:
6.67 cm
Step-by-step explanation:
since 1 cm is 15 miles we will divide 100 miles by 15 miles
100/15=6.67
now we will take out number and multiply it by the number of cm
6.67 x 1 = 6.67
so on the map they are 6.67 cm apart.

a fair coin is flipped four times . use a tree diagram to find the probability of observing. exactly two heads . enter youe answer as a percentage to the nearesr percent
The probability of observing exactly two heads when a fair coin is flipped four times is found to the nearest percent to be 38%.
What is probability?It is the ratio that shows the likelihood of an event occurring out of all the other possible events.
The tree diagram is drawn. The tree diagram is labeled such that the red lines represent the number of times exactly two heads are observed. The total number of events where exactly two heads are observed = 6The total number of events = 16∴ P( Getting exactly two heads when a coin is flipped four times) = 6/16 = 0.375
Convert the into percent as follows:0.375*100 = 37.5%
≈ 38%
Therefore, we have found the probability of observing exactly two heads when the coins are flipped four times to the nearest percent as 38%.
