What is the radius of the copper circle?
9514 1404 393
Answer:
(1+√2)/2 ≈ 1.207 cm
Step-by-step explanation:
The angled flats are at 45°, so the length in the direction of a vertical or horizontal radius is (1 cm)/√2 = (1/2)√2 cm. The remaining length of that radius is half the length of a flat, so is 1/2 cm. The total length of the radius is ...
1/2 + 1/2√2 = (1+√2)/2 ≈ 1.207 cm
_____
In trigonometry terms, the length of the flat is ...
1 cm = 2(r)(tan(45°/2))
so the radius is ...
r = (1 cm)/(2·tan(22.5°))
r = (1/2)cot(22.5°) ≈ 1.207

Find the area of the figure
Answer:
16.28 m^2
Step-by-step explanation:
The bottom portion of this figure is a trapezoid with lengths 4 m and 6 m.
Thus, the average length of this trapezoid is 5 m, and the height is 2 m. This leads to (5 m)(2 m) = 10 m as the area.
The upper portion is a semicircle of radius 2 m. The area of this semicircle is
A = (pi)r^2 / 2, which here is A = (pi/2)(2 m)^2, or approximately 6.28 m^2.
Thus, the area of the entire purple figure is 16.28 m^2.

Mr jb has a rectangular lot that measure 550 meters by 0.75 km.What is the area of the land in square meter. He is selling the whole lot for 206, 250,000 pesos, how much is the price per square meter
Answer:
The area in square meter is 412,500 square meters
the price per square meter is 500 pesos per square meter
Step-by-step explanation:
Firstly, let us get the measure of the dimensions in meters
Mathematically, 1000 m = 1 km
Thus;
0.75 km = 0.75 * 1000 = 750 m
The area of a rectangle is the product of its side lengths
mathematically, we have this as;
550 * 750 = 412,500 square meters
To get the price per square meter, we have to divide the price of the whole plot by the area
So we have ;
(206,250,000) pesos / 412,500 square meters
= 500 pesos per square meter

........Option C ) n × 2 = t
Step-by-step explanation:
Hey there!
In (a) part let us take the value of n as 1 first.
n + 2
=> 1+2
= 3
But it doesn't get matched with t.
So, (a) option cancelled.
In (b) part, let us take the value of n as 1.
n - 2
=> 1 - 2
= -1
But this also didn't match with t.
Option (b) cancelled.
In (c) part, let us take the value of n as 1.
n × 2
=> 1 × 2
= 2
Matched! Let us check further. Taking value of n as 2,
=> 2 × 2
= 4
Matched again! So, (c) part is the correct answer.
Let us take the value of n as 1. (For both option (d) and (e))
n + 3
=> 1 + 3
= 4 (wrong)
n + 4
=> 1 + 4
= 5 (wrong)
So, (c) part is the right answer.

Bank a charges a six dollar service fee and $.10 for each check written. Bank be charges $5.20 for each check written how many checks does a person need to write each month for the two banks to charge the same amounts in fees?
Answer:
A person needs to write each month 1.17 checks for the two banks to charge the same amounts in fees.
Step-by-step explanation:
You can write an equation in which the amount charged by bank a is equal to the amount charged by bank b. The amount bank a charges is 6 plus 0.10 for the number of checks written and the amount bank b charges is 5.20 for the number of checks written.
6+0.10x=5.20x, where x is the number of checks written
Now, you can solve for x to find the number of checks written where the two banks charge the same amounts in fees:
6=5.20x-0.10x
6=5.10x
x=6/5.10
x=1.17
According to this, the answer is that a person needs to write each month 1.17 checks for the two banks to charge the same amounts in fees.

Make q the subject of the formula p = 2q2 .
Answer:
q = ± p/2
Step-by-step explanation:
Given
p = 2q² ( divide both sides by 2 )
= q² ( take the square root of both sides )
± = q p/2
Step-by-step explanation:
[tex]p = 2q^2\\q^2 = \frac{1}{2}p\\q = \pm\sqrt{\frac{1}{2}p}\\q = \pm \frac{1}{2}\sqrt{2p} \qed[/tex] Q.E.D.
Solve 6f-4g=1,6f-6g=5
Answer:
The solution is (-1/2, -2)
Step-by-step explanation:
Given 6f-4g=1,6f-6g=5, write these in columnar form:
6f-4g=1
6f-6g=5
Change all of the signs in the first equation:
-6f + 4g = -1
6f-6g=5
-------------------
-2g = 4, and so g = -2
Substituting -2 for g in either equation enables us to find f. Let's use the first equation: 6f - 4(-2) = 5 yields 6f + 8 = 5, or 6f = -3
Then f = -1/2 and g = -2. The solution is (-1/2, -2)

There were 25 problems in Mark's test. 92% of the problems he answered correctly. How many wrong answers were in Mark's test?
Answer:
2 incorrect answers
Step-by-step explanation:
If you take the percentage correct, you will notice its a particularly high score for the amount of questions. In this case, instead of using a really long theorem, its much simpler to just input numbers.
To find your score on a test out of 100%, you take your amount correct and divide it by the total number of questions, then multiply by 100.
If you take 24/25, you get 0.96, which if multiplied 100*0.96=96%
Now its simple, just go 23/25 to get 0.92, multiplied 100*0.92=92% correct, 25-23=2 so the amount of incorrect answers would be 2.
In a class of 19 students, 12 are female and 13 have an A in the class. There are 4 students who are male and do not have an A in the class. What is the probability that a student chosen randomly from the class does not have an A?
answer is
6/19
× whats the point of this
The likelihood of selecting a classmate at random who does not have an A is 6/19.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
To find the probability of a student not having an A, we need to first find the total number of students who do not have an A.
The number of students who have an A is 13, so the number of students who do not have an A is:
19 - 13 = 6
Out of these 6 students, 4 are male and 2 are female.
So, the probability of choosing a student randomly who does not have an A is:
P(not A) = number of students without an A / total number of students
P(not A) = 6 / 19
Therefore, the probability of choosing a student randomly from the class who does not have an A is 6/19.
