Answer:
30 ft
Step-by-step explanation:
The Pythagorean theorem can be used to find the length of the unknown side. It tells you the sum of the squares of the legs is equal to the square of the hypotenuse.
12² +a² = 13²
a² = 169 -144 = 25
a = √25 = 5
The sum of the side lengths is ...
(12 +5 +13) ft = 30 ft
The perimeter is 30 feet.

Step-by-step explanation:
The formula for the area of a circle is pi x radius to the power of 2. What number to the power of 2 is 196? 14.
So, the radius is 14.
The formula for the circumference of a circle is pi x diameter. If the radius is 14, the diameter is 28.

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?
Answers
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

Under the total column we know that all those values MUST add up to 237
So X + 63 + 66 = 237
Or x = 108 (7th grade total)
Now let’s find another one that we can easily fill in.
Under neutral we know those values must add up to 45
So 17 + 8 + X =45
X = 20 (7th grade neutral)
Now with this information we can fill out 7th grade happy.
15 + 16 + 20 + X + 22 = 108
X = 35 (7th grade happy)
Now we can solve 6th grade happy
X + 35 + 25 = 79
Or x = 19 (6th grade happy)
Another easy one is unhappy total
9 + 16 + 12 = X
Or X = 37 (unhappy total)
Now let’s solve 6th grader very unhappy with new information we found
X + 9 + 17 + 19 + 12 = 63
Or x = 6 (6th grade very unhappy)
Using that we can find 8th grade very unhappy
6 + 15 + X = 31
Or x = 10 (8th grade very unhappy)
Now solve 8th grade very happy
10 + 12 + 8 + 25 + X = 66
Or x = 11 (8th grade very happy)
Now solve very happy total and that’s all
12 + 22 + 11 = X
X= 45 (very happy total)
Now to check our work do all the mood totals add up?
31 + 37 + 45 + 79 + 45 = 237 which checks out

Solution:
The perimeter of the triangle is basically the sum of its sides.
[tex]\rightarrow P = (0.3x + 24) + (5x) + (0.2x - 15)[/tex]
Open the parenthesis:
[tex]\rightarrow P = 0.3x + 24 + 5x + 0.2x - 15[/tex]
Combine like terms:
[tex]\rightarrow P = x(0.3 + 0.2 + 5) + (24 - 15)[/tex]
Simplify the equation:
[tex]\rightarrow P = x(5.5) + (9)[/tex]
Further simplify:
[tex]\rightarrow P = 5.5x + 9[/tex]
Option D is correct.
Perimeter=Sum of three sides

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.
Answers
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%.
