If the diameter of a circle is 3 feet what is the circumference
Answer:
9.42
Step-by-step explanation:
C=2πR
because your diameter is 3, your radius is 1.5, so just plug in your number.
C=2π(1.5)
C=9.42
R is partly constant and partly varies with E, when R=530,E=1600 and when R=730,E=3600
Find the formular which connects R and E
Find R when E=1300
Hi there!
Please check the answer of the image attached for explanation.
Hope this helps....
The value of R at E = 1300 is 500 and the Equation that satisfies R and E is 10R = E + 3700.
What is a linear equation?
Because a straight line emerges when we attempt to display the graph of the provided linear function, a linear equation is known as linear.
Given, R is partly constant and partly varies with E, when R=530, E=1600, and when R=730, E=3600
Since R is partly constant and partly depends on E.
Let b Be the constant part of R and a be the part of R that varies with E
Thus,
R = a * E + b...(1)
Given at E is equal to 1600 R is 530 and at E is 3600 R is 730
Substituting these values in equation 1
530 = 1600a + b......(2)
730 = 3600a + b........(3)
From comparing equation 2 and equation 3
2000a = 200
a = 1/10
from equation 2
b = 370
Thus, the equation in R and E:
R = 1/10 E + 370
=> 10R = E + 3700
Value of R at E = 1300
R = 130 + 370
r = 500
Therefore, the Equation that satisfies R and E is 10R = E + 3700.

Find the slope of the line that passes through (6, 2) and (10,3).
A -1/4
B 4
C 1
D O 1/4
Answer:
D
Step-by-step explanation:
Firstly,you must divide (6,2) to (x¹y¹).After that,you must divide (10,3) to (x²y²).Then you must substract (y²-y¹,x²-x¹).It will be like this (3-2,10-6).So the correct answer is 1,4 (D).Hope you will understand!
[tex]\huge\sf\orange{Ꭺղsฬєɾ :- }[/tex]
★ Option D) 1/4 is a correct answer.
Given,
• A = (6,2)
• B = (10,3)
__________________
Formula :
Slope = y2 - y1/x2 - x1
__________________
• A (6,2)
x1 = 6
y1 = 2
• B (10,3)
x2 = 10
Y2 = 3
Now, Slope of AB
[tex] = > \frac{3 - 2}{10 - 6} [/tex][tex] = > \frac{1}{4} [/tex]★ Hence,the slope of the line that passes through (6, 2) and (10,3) is 1/4

For each value of y, determine whether it is a solution to 2y> 18.
Answer:
2y>18......
2(8)= 16>18 no
2(11)= 22>18 yes
2(12)= 24>18 yes
2(6)= 12>18 no
Answer:
Step-by-step explanation:
We have 4 value of y : 8 ; 11 ; 12; 6
To determine whether it is a solution to the inequality 2y > 18, we have to substitute these values in
Substitute 8 in, we get : 2 x 8 > 18
16 > 18 (not true)
So, this is not a solution
Substitute 11 in, we get : 2 x 11 > 18
21 > 18 (true)
So, this is a solution
Substitute 12 in, we get : 2 x 12 > 18
24 > 18 (true)
So, this is also a solution
Substitute 6 in, we get : 2 x 6 > 18
12 > 18 (not true)
So, this is not a solution
There are 2 values that satisfy this inequality for y : 11 and 12
Find an overestimate for 42 x 59 by adjusting each factor up to the next ten.
Answer:
Step-by-step explanation:
"To the next ten" means we will turn 42 into 50 and 59 into 60.
Since we are adding 8 to 42 and 1 to 60 this will not be exactly right, hence why it is an overestimate.
If, 5 * 6 = 30
Then, 50 * 60 = 3,000

If m∠CED = 56° and m∠AEB = (7x – 8)° then what is m∠BEC?
Using the definition of angles on a straight line, the measure of angle BEC is: 62°.
What are Angles on a Straight Line?Angles that lie on a straight line add up to 180 degrees.
Thus, given that EB bisects ∠AEC, therefore:
m∠BEC = 1/2(180 - m∠CED)
Plug in the values
m∠BEC = 1/2(180 - 56)
m∠BEC = 1/2(124)
m∠BEC = 62°
Thus, using the definition of angles on a straight line, the measure of angle BEC is: 62°.

the popularion of a city increases by 7% every year. if its population today is 300,000, what will its population be in 4 years. Write as an expression.
Answer:
Expression : 300,000 + 7x% = a
a = 384,000
Step-by-step explanation:
a = population in 4 years
x = every year increased
Expression: 300,000 + 7x% = a
300,000 + 7x% = a
replace x what will its population be in x years variable (this is 4)
300,000 + 7(4)% = a
multiply 7(4)
300,000 + 28% = a
Add 28% of 300,000 to 300,000
384,000 = a
1. A basketball is thrown from the roof of a 50-foot building. It reaches a
maximum height of 86 feet 1.5 seconds after the ball is thrown.
• Write a function representing the problem situation.
Identify the domain, range, vertex, y-intercept, and zeros of the
function, and justify their meaning in the problem situation.
Answer:
Step-by-step explanation:
The basketball reaches a maximum height of 86 feet after 1.5 seconds, so the vertex is (1.5, 86).f(x) = a(x − 1.5)² + 86We know the initial height is 50 feet, so plug in the point (0, 50) to find the value of a.50 = a(0 − 1.5)² + 86-36 = 2.25aa = -16f(x) = -16(x − 1.5)² + 86Simplify to get the standard form.f(x)
= -16(x − 1.5)² + 86f(x) = -16(x² − 3x + 2.25) + 86f(x) = -16x² + 48x − 36 + 86f(x) = -16x² + 48x + 50
find the value of 0 round to the nearest whole degree
Answer:
27°
Step-by-step explanation:
we have the 'opposite' as length 2 is opposite the angle θ
we have the adjacent (length 4) which is next to the angle θ
the hypotenuse is the longest side (we don't need)
Using SOHCAHTOA
we use TOA as O is opposite and A is adjacent
tanθ = opposite ÷ adjacent
tanθ = 2 ÷ 4
using the inverse sign to find θ
θ = tan⁻¹(2/4) = 27° (to the nearest whole degree)

Even though independent gasoline stations have been having a difficult time, Susan Solomon has been thinking about starting her own independent gasoline station. Susan’s problem is to decide how large her station should be. The annual returns will depend on both the size of her station and a number of marketing factors related to the oil industry and demand for gasoline. After a careful analysis, Susan developed the following table:
The maximax decision for Susan would be to have a very large gasoline station.
What is a Maximax decision?This is the decision that provides a person with the maximum possible profits or advantages.
What is the Maximax decision in this case?In this case, the maximax decision is a very large gasoline station because the possible profits add up to $325,000 ($25,000 + $300,000) and the possible losses are $100,000. This implies with this type of gasoline station Susan could maximize her profits even though there is a risk.
