If the price of a yo-yo in a shop increased by 20% and is now $18.00, what was the original price?
So $18 would be 120%. This is because the yoyo is 100% and you increased by 20%. If this was a calculator question, you would do 18 / 120 than times by 100 to get 100%. Naturally it would just be 18/12 x 10 = 15. so $15 is 100% or the originally price.
Hope it helped :)
The original price was $15.00
The price of the yo-yo increased by 20% and went to $18.00. Assuming the original price is x, the original price would be:
18 = x × (1 + 20%)
18 = x × 1.20
18 = 1.20x
x = 18 / 1.20
x = $15.00
In conclusion, the original price was $15.00 but after the price increased by 20%, it went to $18.00.

An angle measures 132.6 more than the measure of a supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
If the angle measures x, then the supplement measures 180-x.
This means x-132.6=180-x, and thus x=156.3
This means the angles measure 156.3 and 23.7 degrees.
A child learns new words very quickly, but their vocabulary grows slower as they grow up. There is no upper-limit to the size of a person's vocabulary, so a logarithmic growth model is reasonable. The number of words can be related to the child's age (in months) according to the following formula: W(m)=10,000 ⋅ log(m) − 13,000
where m is the number of months in a person's age.

When it comes to fat, there's one type you don't want to cut back on: omega-3 fatty acids. Two crucial ones -- EPA and DHA -- are primarily found in certain fish. ALA (alpha-linolenic acid), another omega-3 fatty acid, is found in plant sources such as nuts and seeds. Not only does your body need these fatty acids to function, but also they deliver some big health benefits.

Answer:
r = 1.7389 in
Step-by-step explanation:
(A) Volume of hollow block = 540 in^3
(B) volume of block without Hollows = b×d×h
= 6 ×16 ×8
= 768 in^3
(C) volume of 3 hollows = 3 ×( pi ×r^2 h)
= 3 ×( pi ×r^2 ×8)
= 24 ×pi ×r^2
solve,
A = B - C
540 = 768- (24 ×pi ×r^2)
r^2 = (768- 540) / 24 pi
r = root(3.023943919)
r = 1.7389 in
The Wares want to buy a new computer. The regular price is $1049.the store is offering 20% discount and a sales tax of 5.25% is added after the discount .what is the total cost?
Answer:
$883.26
Step-by-step explanation:
Multiply the regular price ($1,049) by the Percent Discount (20%). To do this, multiply 1,049 by 0.2 :
1,049(0.2)=$209.8
After multiplying, you get the amount taken off by the discount. So you subtract the amount you got ($209.8) from the original amount ($1049) :
$1049-$209.8=$839.2
Now that you've calculated the discount price, you can calculate the sales tax. Make sure you do this part second, because it says to do so in the problem.
To calculate the sales tax, you do the same as above. Multiply your NEW cost ($839.2) by the sales tax (5.25%). The equation is:
$839.2(5.25%)=$44.058
Round $44.058 to $44.06. Since this is a Sales Tax, you add this on to your previous amount of $839.2
$839.2+$44.06=$883.26
The final cost of the computer is $883.26
A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 49.0 and 54.0 minutes. Find the probability that a given class period runs between 50.75 and 51.75 minutes.
Find the probability of selecting a class that runs between and minutes.
Answer: 0.050
I just did it and I got it right.
The probability of selecting a class that runs between 51.0 and 52.5 minutes is 0.3 or 30%.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
Since the lengths of the classes are uniformly distributed between 49.0 and 54.0 minutes, the probability of a class running between any two values within this range is proportional to the length of the interval between these two values.
The total length of the possible class periods is:
54.0 minutes - 49.0 minutes
= 5.0 minutes
So, the probability of a randomly selected class running between 50.75 and 51.75 minutes can be calculated as follows:
Length of the interval
= 51.75 minutes - 50.75 minutes
= 1.0 minute
Probability = (Length of the interval) / (Total length of possible class periods)
Probability = 1.0 minute / 5.0 minutes
Probability = 0.2
Therefore, the probability of a given class period running between 50.75 and 51.75 minutes is 0.2 or 20%.
Similarly, the probability of selecting a class that runs between a and b minutes, where a and b are between 49.0 and 54.0 minutes and a < b, is given by:
Probability = (Length of the interval between a and b) / (Total length of possible class periods)
Probability = (b - a) / 5.0
For example, if we want to the probability of selecting a class that runs between 51.0 and 52.5 minutes, we would have:
Probability = (52.5 - 51.0) / 5.0
Probability = 0.3 or 30%
Thus,
The probability of selecting a class that runs between 51.0 and 52.5 minutes is 0.3 or 30%.

Look at the function f(x) = −x + 5. Which of the following describes the domain and range of the function and its inverse?
Answer:
the first
0 5
5 0
Step-by-step explanation:
the question should be : "which describes a POSSIBLE domain and range definition of the function and is inverse ?"
because this is just a matter of definition. the function itself would not suggest any limits.
and in that regard the function definition is basically irrelevant.
the domain of any basic function is the range of the inverse, and the range of the basic function is the domain of the inverse.
so, the second set of definitions is not possible, if we are really trying to define the inverse function.

3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
x+20
———— • 5 = 0 • 5
