Answer:
π∗9 or 28.28
Step-by-step explanation:
With the equation of A = \pi * r^2A=π∗r
2
, We find that the r - (radius) = 3, so it would be \begin{gathered}\pi *3^2\\\end{gathered}
π∗3
2
Answer:
A, C, D
Step-by-step explanation:
In a proportional relationship, y = kx, k is the constant of proportionality.
A)
4y = x
y = 1/4 x
k = 1/4 Yes
B)
y = 4x
k = 4 No
C)
32y = 8x
y = 8/32 x
y = 1/4 x
k = 1/4 Yes
D)
y = 0.25x
k = 0.25 = 1/4 Yes
E)
1/4 y = 2x
y = 4 * 2x
y = 8x
k = 8 No
Answer: A, C, D
7 English and 6 Science
There are 7 * 6 ways this can be put together. Which makes 42.
Take a look at the diagram below. There are 6 possible science teachers that the student could choose after choosing E1 which is the first English teacher. Each of the remaining 6 english teachers also allow for 6 science teachers.
6*7 = 42
Answer:
The value of y is 4
The equation of line is y = x + 7 .
Step-by-step explanation:
Given as :
The points are
(
,
) = (- 3, y)
(
,
) = (- 9, -2)
The slope = m = 1
Now,<u> The slope is calculated in points form</u>
So, Slope = 
I.e m = 
or, 1 = 
or, 1 = 
or, 1 × (-6) = - 2 - y
or, - 6 = - 2- y
or, y = - 2 + 6
∴ y = 4
So, The new points as
(
,
) = (- 3, 4 )
(
,
) = (- 9, -2)
<u>So, the equation of line in slope - point form can be written as</u>
y -
= m ( x -
)
i.e y - 4 = ( 1 ) × ( x - (-3) )
or, y - 4 = x + 3
∴ y = x + 3 + 4
Or, y = x + 7
So, The equation of line is y = x + 7
Hence The value of y is 4
And The equation of line is y = x + 7 . Answer
The answer is 10√3 because
10√3 is equal to approximately 17.32051 and the formula for finding the area of a square is length multipled by width so 10√3 x 10√3 is equal to 300 or 17.32051 x 17.32051 is equal to 300
