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
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.

3/7 of the students in a school are sixth graders. how many sixth graders are there if the school has 28 students.
Answer:
There are 12 6th graders
Step by Step Explanation:
Because there are 28 students, you have to make a fraction wuth a denominator of 28. To do that, you have to multiply the denominator of 3/7 by 4 to get 3/28. To get an equivalent fraction, you need to multiply the numerator by 4 too, because whenever you do something to the denominator of a fraction, you must mirror it for the numerator and vice versa. so 3/7 × 4 equals 12/28. So 12 out of the 28 students are 6th graders.
y is directly proportional to the square root of x
x
If
y
=
60
when
x
=
36
find,
x
when
y
=
80
Answer:
Step-by-step explanation:
y=k[tex]\sqrt{x}[/tex]
60=k[tex]\sqrt{36\\}[/tex] =k6
k=60/6 =10
This is your equation
y=10[tex]\sqrt{x}[/tex]
Put the numbers in
80=10[tex]\sqrt{x}[/tex]
80/10=8 then you have to square this so
[tex]8^{2}[/tex]=64
x=64

a random selection of indoors and outdoors pool managers are surveyed about the number of people in each age group that swim there. results from the survey are displayed in the two way table. based on the data, does there appear to be an association between pool type and age group? explain your reasoning
Answer:
Yes, there is a relationship between.
Step-by-step explanation:
From the table, for people younger than 18 years, 317 use outdoor pool while 41 use indoor pool.
Thus;
% younger than 18 that use indoor pools = (41/(317 + 41)) × 100% = 11.45%
% younger than 18 that use indoor pools = (317/(317 + 41)) × 100% = 88.45%
So we can see that there is a relationship whereby the percentage of younger than 18 that use indoor pools is less than that of those that use outdoor poles.
In the same vein, by inspection, percentage of 18 or older that use outdoor poles are more than the percentage of % younger than 18 that use indoor pools.
Thus, there is a relationship between pool type and age group.

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.

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

........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.
Hope it helps :)
The radius of a circle is 5 m. Find its circumference in terms of pi.
Answer:
C=2(pi)r
C=10pi m
The formula for the circumference of a circle is C = 2πr, where "C" is the circumference, "π" is pi (approximately equal to 3.14), and "r" is the radius.
Given that the radius of the circle is 5 inches, we can substitute this value into the formula to find the circumference:
C = 2πr
C = 2π(5)
C = 10π
Therefore, the circumference of the circle is 10π inches.
