Answer:
3/24 = 7/x
c = $56
Step-by-step explanation:
A percent proportion is just basically a ratio, I could also write this as 3:24 = 7:x, it really doesn't matter. What does matter is that this is considered a percent proportion. Now, to solve a percent proportion, we have this formula.
a/b = c/d
Say b is the unknown value, we would do (a*d)/c, say a was the unknown value, we would do (b*c)/d, Basically, A and D are linked together and B and C are linked together so you take the two values that are linked together first, multiply them together, and divide by the pair that has a partner that is unknown.
A coin has heads on one side and tails on the other. The coin is tossed 12 times and lands heads up 4 times. Which best describes what happens when the number of trials increases significantly?
A. The observed frequency of landing heads up gets closer to the expected
frequency based on the probability of the coin landing heads up.
B. The observed frequency of landing heads up will always be 1/3 of the number of
tosses.
C. The expected frequency based on the probability of the coin landing heads up
gets closer.
D. The expected frequency based on the probability of the coin landing heads up
gets closer to the observed frequency.

Step-by-step explanation:
The only answer for this is C
The correct option is option C i.e. "If the ratio of the arc length to r is 1, then the measure of θ is 1 radians".
What is Arc length?The arc length is defined as the interspace between the two points along a section of a curve.
Here, we know that,
angle = arc length / radius ............(i)
If arc length / radius = 1 ............(ii)
then from eq. (i) and (ii), we get
angle = 1
θ = 1
Thus, The correct option is option C i.e. "If the ratio of the arc length to r is 1, then the measure of θ is 1 radians".

Find the slope of the line
8 – 7x = 4y
Step-by-step explanation:
y = mx + c
8 - 7x = 4y
4y = 8 - 7x
y = (8 - 7x)/4
= 2 - 7/4x
y = -7/4x + 2
Slope = m = -7/4
Answer:
slope = - [tex]\frac{7}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
8 - 7x = 4y, that is
4y = - 7x + 8 ( divide all terms by 4 )
y = - [tex]\frac{7}{4}[/tex] x + 2 ← in slope- intercept form
with slope m = - [tex]\frac{7}{4}[/tex]

Boris filled his gas tank three times last week. Here are the amounts of gas he bought (in gallons).
9.94, 1, 19.1
What is the total amount of gas Boris bought last week?
Answer:
30.04
Step-by-step explanation:
You could do this the simple way which is to first grab two numbers in any order and add them together, and after you do that you can add the result to the remaining number or numbers that remain. 9.94 plus 1 is 10.94, and 10.94 plus 19 is 29.94, lastly the .1 from the 19 which finally leads us to the answer of 30.04 gallons that Boris bought last week

Do you practice is yoga for the same amount of time every day after he practices yoga for 18 minutes on Saturday he finished 24% of his daily yoga practice how many more minutes do you still practice yoga on Saturday
Answer:
51 minutes
Step-by-step explanation:
Let the total number of minutes required for daily yoga practice = x
Hence:
24% of x = 18 minutes
24/100 × x = 18 minutes
24x /100 = 18 minutes
Cross Multiply
24x = 100 × 18 minutes
x = 1800 minutes/24
x = 75 minutes.
The total number of minutes for daily yoga practice = 75 minutes
How many more minutes do you still practice yoga on Saturday?
This is calculated as:
75 minutes - 24 minutes
= 51 minutes

a sphere has a volume of 4500 cubic inches. What is the radius off the shpere
Answer:
The radius of sphere with volume 4500 cubic inches is 10.24 inches.
Step-by-step explanation:
Let V be the volume of the sphere
Given
Volume of sphere = V = 4500 cubic inches
Let r be the radius of the sphere
The volume of the sphere is given by the formula
[tex]V = \frac{4}{3}\pi r^3[/tex]
Putting the known values
[tex]4500 = \frac{4}{3} * \frac{22}{7} * r^3\\4500 = \frac{88}{21} * r^3\\r^3 = \frac{21}{88} * 4500\\r^3 = 1073.8636[/tex]
Taking cube root on both sides
[tex]\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403[/tex]
Rounding off to nearest hundredth
The radius is: 10.24 inches.
Hence,
The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Lin is shopping for a couch with her dad and hears him ask the salesperson, "How much is your commission?" The salesperson says that her commission is 5.5% of the selling price. How much commission will the salesperson earn by selling a couch for $495?
Answer:
The salesperson will earn $27.22 as comission by selling a couch for $495.
Step-by-step explanation:
From the information given, you know that Lin's comission is 5.5% of the selling price, so in order to find the amount of the commision the salesperson will earn you have to calculate 5.5% of the selling price:
495*5.5%=27.22
According to this, the answer is that the salesperson will earn $27.22 as comission by selling a couch for $495.

Melanie needs 5,000 chocolates for an event so far she has brought 2 cases of 1,125 chocolates each how many more does she need
Answer:
2750 chocolates
Step-by-step explanation:
Find how much she has bought already:
1,125(2)
= 2,250
Then, subtract this from 5,000
5000 - 2250
= 2750
So, she still needs 2750
Answer:
2,750
Step-by-step explanation:
2 cases of 1,125 chocolates = 2,250 chocolates
5,000 - 2,250 = 2,750 more chocolates needed
(that's also 3 cases of chocolates needed :p)
