Answer:
24.99 cm
Step-by-step explanation:
We are provided with the radius of the circle so we can use that to solve for the circumference(perimeter) of the circle. The formula to solve for the circumference is 2*pi*r.
2*pi*7 = 14pi = 43.98 cm
Although this is the circumference of the entire circle... To solve for the circumference of a quarter-circle we must find the quarter of that:
43.98 * 1/4 = 10.99 cm
We are already provided with the other two sides, which are both equal to 7 cm since they are radii.
Perimeter = 10.99 +7 + 7 = 24.99 cm
Hope this helps!

All angles of any triangle must add up to 180 degrees.
So, (10x - 4) + (8x + 3) + 91 = 180 ; Solve for "x" ;
___________________________________________
10x - 4 + 8x + 3 + 81 = 180 ;
Combine the "like terms" on the left-hand side of the equation:
___________________________________________
+10x + 8x = 18x ;
- 4 + 3 + 8 = 7 ;
____________________________
18x + 7 = 180 ;
___________________________________________
Subtract "7" from each side of the equation:
___________________________________________
18x + 7 - 7 = 180 - 7 ;
___________________________________________
to get:
18x = 173 ;
_________________________________
Divide EACH side of the equation by "18" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_________________________________
18x / 18 = 173 / 18 ;
_________________________________
x = 9.6111111111111111....
_____________________________________
Write as: 9.611 ; or; 9 11/18.

Step-by-step explanation:
First question: x - 6 means there is a shift to the right.
Second Question: substitute the given values into the original equation for appropriate transformations.
Answer: 3 |x-4| + 2, because vertical stretch multiplies x, horizontal shifts are subtracted or added to x, and vertical shifts are added or subtracted to the entire function.
The correct answer is f=(1/3)m
Answer:
Step-by-step explanation:
Given that a farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant produces
When we consider this graph as a straight line, the two points lying on the line would be
(30, 30) and (34, 28) taking n as horizontal and y vertical
Using two point equation we find that
the equation of the line is
Substitute the points as x =n
is the linear relationship between n and y
