Consider the following ratios and state that whether these ratios forms a proportion?
Case1 - 20 friends to 15 strangers
Case 2 - 4 friends to 3 strangers
A.Yes
B.No
Part B
Find the ratio of the number of friends in Case 1 to the number of friends in Case 2.
Answer: ____________
Note: Type the answer as shown. Ex: (3:8)
Answer:
Prt A- Yes
Part B- 5:1
Step-by-step explanation:
The ratios in cases 1 and 2 form a proportion. This can be seen by dividing case a by 5 which gives 4:3;
i.e 20:15 = 20
15
If you divide both numerator and denominator by 5, we have 4/3.
This shows that case 1 and 2 have the same proportions of friends to strangers.
Part B.
The number of friends in case 1 is 20 while in case 2 is 4.
we have, 20:4
= 20
4
Dividing each by 4, we have 5:1.
This means that the ratio of friends that in case 1 to case 2 is 5:1.

A Web music store offers two versions of a popular song. The size of the standard version is 2.8 megabytes (MB). The size of the high-quality version is 4.4 MB. Yesterday, there were 950 downloads of the song, for a total download size of 3284 MB. How many downloads of the standard version were there?
Number of standard version downloads: ?
Answer:
560 downloads of standard version downloads.
Step-by-step explanation:
Let there were number of standard version of downloads = x
and number of high quality version of downloads = y
There were total 950 downloads of the both type of songs.
x + y = 950 -----(1)
Size of the standard version songs = 2.8 MB
and the size of the high quality version songs = 4.4 MB
Total download size = 3284 MB
2.8x + 4.4y = 3284
7x + 11y = 8210 -----(2)
Multiply equation (1) by 11 (-) equation (2)
(11x + 11y) - (7x + 11y) = 10450 - 8210
4x = 2240
x = 560
There were 560 downloads of the standard version downloads.

Ivy randomly surveys students in her school to learn about mobile phone password use. Of 25 respondents, 14 use a password. Based on Ivy’s data, how many of the 275 students in her school would be expected to use a password?
Answer:154
Step-by-step explanation:
14/ 25 = x/275
multiply 14* 275 then divide by 25 to get 154
Answer:
168
Step-by-step explanation:
If 14/25 have passwords, and there are 275 students in her school, then the equation should be 275/25=12, 12*14=168
A stone fell from the top of a cliff into the ocean.
In the air, it had an average speed of 16. In the water, it had an average speed of 3 before hitting the seabed. The total distance from the top of the cliff to the seabed is 127 meters, and the stone's entire fall took 12 seconds.
How long did the stone fall in the air and how long did it fall in the water?
Answer:
5 seconds.
Step-by-step explanation:
Make an equation.
Time in air = x
Time in water = 12 - x
16x + 36 - 3x = 127
13x = 91
x = 7
12 - 7 = 5

Answer:
14.13
Step-by-step explanation:
Step 1) Find the total area
A = pi x r^2
A = pi x 3^2
A = 9pi
Step 2) Divide the total area by 4
9pi / 4 = 2.25pi
2.25pi = 7.07
A = 7.07 square feet

find a rational number between 3 and 4
Answer:
3.1, 3.2, 3.3
Step-by-step explanation:
There are infinite options but a rational number is a fraction, decimal, or repeating decimal.
3 [tex]\frac{1}{3}[/tex] is an example of a fraction between 3 and 4
3.2 is an example of a decimal between 3 and 4
3.3333333... is an example of a repeating decimal between 3 and 4
Answer: 3.2526252625...
Explanation: The number above would be a rational number because it's a repeating decimal. Notice that in the decimal above, 2526 is a group of repeating digits and repeating decimals are rational.

An hour before show time, only 342 people are seated for a rock fest. According to ticket sales, 91% of the people have yet to arrive. How many tickets were sold for the rock fest? Explain your thinking.
Answer:
3800
Step-by-step explanation:
342 is the 9 percent that have shown up. If you divide that by nine you would get on percent of the total which comes out to be 38. so you multiply 38 by 100 and get 3800 which is 100% of the tickets sold.

Answer:
x is 60°
y is 30°
(would really, reallly appreciate the brainliest)
Step-by-step explanation:
x can be seen as what's needed to do a full 180 ° turn when you already turned 120°
y is 60° bc the sum of all tree angles of a triangle is always 180°
90° are given with the little square, 60 by the similar reasoning as above
Answer:
Step-by-step explanation:
L an M are parallel & P is transversal.
So, 120, x are co-interior angles, ie 180
x +120 = 180
x = 180 - 120
x = 60
The angle vertically opposite to x, will have the same value of x.
Vertically opposite angles are equal
In triangle, sum of angles = 180
60 + 90 + y = 180
150 + y =180
y =180 - 150
y =30
Andre notices that he is a little taller than Heather, who described her height as h is greater than 150 and h is less than 160 Andre is also shorter than their math teacher who is 164 centimeters tall.
Answer:
a> ha<164Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Andre notices that he is a little taller than Lin, who described her height as h > and 150 h < 160 but andre is also shorter than their math teacher who is 164 centimeters tall. select the two inequalities that describe andress height
Please have a look at the attached photo.
My answer:
Math teacher's height: 164 cm
Let Andre height is :a
We have Heather height: h
<=> h > and 150 h < 160
<=> 150 < h < 160
=> two inequalities that describe Andres height
a> ha<164Hope it will find you well
The probability of a chance event is 0.8, it is __________ to happen when compared to a chance event with a probability of 0.9. Select one: equally likely less likely more likely both more and less likely
Answer:
less likely
Step-by-step explanation:
In the question, we are to choose which of the options best fit into blank space.
Talking about probabilities, the probability of events ranges from 0 to 1. With 1 being the highest value the probability of an event can take while 0 is the lowest value the probability of an event can take. The probability of an event can neither be negative, nor greater than 1. It lies between 0 and 1
Now, the closer a probability is to 1, the greater the likelihood of that particular event happening. Events having probabilities closer to 1 are more likely to occur than those farther away from 1 or closer to zero.
In this question, 0.9 is a greater value compared to 0.8. Thus, an event of probability 0.9 is more likely to happen compared with an event with probability of 0.8
In other words, an event with probability 0.8 is less likely to occur compared with an event with a probability value of 0.9
how can you determine the x value whether it is in the domain of h
Answer:
Well, because this is a khan academy question i guess ill be safe to answer it.
0 is in the domain
4 is in the domain
5 is NOT in the domain.
Step-by-step explanation:
If you plug in 5, you are left with
[tex]\frac{4}{5 - 5}[/tex] = [tex]\frac{4}{0}[/tex] = undefined
However, if you plug in any other value in that list, you are left with a number.
Remember, it isn't in the domain if the number is imaginary (like square root of a negative number) or the answer results in an undefined :)

A bank account has a beginning balance of $560.00. After 6 months, the balance in the account has increased to $572.60. What interest rate is being earned annually on this account?
2.20%
.045%
2.25%
4.5%
Answer:
D. 4.5%.
Step-by-step explanation:
Interest earned in 6 months = 572.6 - 560 = $12.60.
As a percentage this is (12.60 * 100) / 560
= $ 2.25%.
So the annual interest is 2 * 2.25
= 4.5%.
Answer:
4.5%

An amusement park ride is made up of a large circular frame that holds 50 riders. The
circumference of the frame is about 138 ft. What is the diameter of the ride? Round to the nearest
tenth.
Help Please
Answer:
The diameter of the ride is 44 feets.
Step-by-step explanation:
We have,
The circumference of the frame is about 138 ft.
It is required to find the diameter of the ride.
The circumference of means that the outer covering of the circle. It is given by the formula as follows:
[tex]C=2\pi r[/tex]
r is radius
Since, 2r = d, diameter of circle
[tex]C=d\pi \\\\d=\dfrac{C}{\pi}\\\\d=\dfrac{138}{3.14}\\\\d=43.94\ ft[/tex]
or
d = 44 feets
So, the diameter of the ride is 44 feets.
