what is the diameter of a pond with a area of 4069.44
Answer:
72
Step-by-step explanation:
Formula: A= 3.14r^2
4069.44^2 = 3.14r^2
(divide both sides by 3.14)
1296=r^2
(find sqr root of 1296)
36=r
to find the diameter with the radius, multiply radius by 2... 36*2= 72
The diameter of a pond with an area of 4069.44^2 is 72!

y= 56-10
y= 46°
Systems of equations by substitution
Answer:
(-2,1)
Step-by-step explanation:
Substitute the value of y (x+3) from one equation into the second equation (2x+5)
X+3 = 2x + 5
add -2x to both sides
-x+3=5
add -3 to both sides
-x=2
x=-2
substitute -2 for x in either equation to find y.
y=-2+3
y=1
Check your answer by substituting x and y into either equat to make sure it equals.
y=x+3
1=-2+3
1=1
or
y=2x+5
1=2(-2)+5
1=-4+5
1=1
A university has 40,140 students. In a random sample of 210 students, 14 speak three or more languages. Predict the number of students at the university who speak three or more languages.
Answer:
2676 students
Step-by-step explanation:
Total number of students =. 40,140
During study:
Sample size = 210
Number of samples who speak 3 or more languages = 14
Proportion who speak 3 or more languages :
14 / 210 = 0.0666666
Applying the proportion to the total. Population :
0.0666666 * total number of students
0.0666666 * 40140
= 2675.997324
= approximately 2676 students

One of the teachers at a school is chosen at random. The probability that this teacher is female is 3/5 There are 36 male teachers at the school. Work out the total number of teachers at the school.
Answer:
90 total teachers
Step-by-step explanation:
The total number of teachers at the school is 90 whereas there are 36 female and 54 male teachers.
Probability-based problem:What information do we have?
Probability teacher is female = 3/5
Number of male teachers = 36
Probability teacher is male = 1 - (3/5)
Probability teacher is male = 2/5
Total number of teacher = (5/2)(36) Total number of teacher = (5)(18)Total number of teacher = 90 teachers
the total number of teachers in the school is 90 teachers.

A 10% increase followed by another 10% increase is not the same as a total increase of
20%.
What is the total percentage increase?
Answer:
21%
Step-by-step explanation:
Another 10% increased means it becomes 110*110/100 = 121. The first 10% increase means the second 10% increase will be an actual 11% increase from the original, so it will be a total of 21%.
Answer:
21%Step-by-step explanation:
Because the first 10% increase is calculated as 10% of what you started with. The second 10% is 10% of what you started with plus 10% of the increase caused by the original 10% increase.
Let's do the maths…
Let's start with 100 to make things easy.
We know that 10% of 100 is 10.
We know that 20% of 100 is 20.
So if we increase 100 by 10% we get 110.
If we increase 100 by 20% we get 120.
Now lets do the 10% plus 10%.
From the first 10% increase we were left with 110.
Now if we take 10% of the 110 we have 11.
Add that to the 110 and we get 121.
This is why people are surprised how quick a lone can rise if we don't pay it off. We are paying interest on the basic sum plus interest on the interest, then interest on the interest on the interest.

A survey was conducted to see how many phone calls people made daily. The results are displayed in the table below:
From the given frequency table,
Frequency represents the number of people who made the calls.
Total number of people who made the calls = 16 + 11 + 5 + 3 + 1
= 36
Number of people who made less than 13 calls = 16 + 11 + 5
= 32
Number of people who made at least 9 calls = 5 + 3 + 1
= 9
Percentage of people who made at least 9 calls = [tex]\frac{\text{Number of people who made at least 9 calls}}{\text{Number of people who made the calls}}\times 100[/tex]

A diameter is a chord.
True or false and why?
Answer:
true.
A chord that passes through the center of a circle is called a diameter and is the longest chord.
Step-by-step explanation:
A diameter satisfies the definition of a chord, however, a chord is not necessarily a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center. Thus, it can be stated, every diameter is a chord, but not every chord is a diameter.

Answer:
Step-by-step explanation:
Complete Question:
The amount of money, y, pizzeria W makes by selling x pizzas can be modeled by the equation y = 15x. The relationship of the amount of money pizzeria L makes is shown in the following graph.
Which pizzeria makes more money per pizza?
A. Pizzeria L makes more money per pizza.
B. Pizzeria W makes more money per pizza.
C. They make the same amount per pizza.
Answer:
B. Pizzeria W makes more money per pizza.
Step-by-step explanation:
The proportional relationship showing how amount of money made(y) is related to the amount of pizzas sold (x) for pizzeria W is given by the equation y = 15x.
the constant of proportionality/unit rate, k = 15.
This represents the amount in dollars, made per pizza.
So, Pizzeria W makes $15 per pizza.
For Pizzeria L, using any point on the line, say, (2, 24),
k = y/x = 24/2 = 12.
This represents the unit rate, which is the amount Pizzeria L makes per pizza.
Thus, Pizzeria L makes $12 per pizza.
We can conclude that, Pizzeria W makes more money per pizza.
Answer:
L
