rounded to the nearest meter?
Answers
Answer:
17 meters
Step-by-step explanation:
the circumference is solved by multiplying the diameter by pi.
the diameter can be found by multiplying the raduis by 2
the diameter is 5.4
5.4 x 3.14
16.956
about 17 meters
Answer:
17[tex]m^{2}[/tex]
Step-by-step explanation:
The cirfumference of a circle when given the radius is 2πr
So pi is 3.14 thus:
2 × 3.14 × 2.7
16.956 [tex]m^{2}[/tex]
When rounding of to the nearest meter check if the number in the tenths side is bigger than 5. It is bigger so we add 1 to the units making it 17[tex]m^{2}[/tex].

24 + 0.44x = 19 + 1.69x
Answers
Answer:
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 + 0.44x - 1.69x = 19
-1.25x = 19 - 24
-1.25x = -5
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 - 19 = 1.69x - 0.44x
5 = 1.25x
1.25x = 5
x = 5/1.25

Which equation represents the perpendicular
bisector of AB whose endpoints are A(8,2) and
B(0,6)?
Answers
Answer:
y = ½x + 2
Step-by-step explanation:
We are given the coordinates of the endpoint as;A(8,2) and
B(0,6)
The midpoint coordinates will be;
((8 + 0)/2, (2 + 6)/2) = (4, 4)
The slope of the midpoint using gradient formula will be;
m = (6 - 2)/(0 - 8)
m = 4/-8
m = -2
Thus, slope of a line perpendicular to the midpoint is;
m_p = -1/m
m_p = -1/-2
m_p = 1/2
Thus, using slope intercept concept, the equation to represent the perpendicular bisector is;
y - 4 = ½(x - 4)
Multiply both sides by 2 to get;
2y - 8 = x - 4
Add 8 to both sides to get;
2y - 8 + 8 = x - 4 + 8
2y = x + 4
Divide through by 2 to get;
y = ½(x + 4)
y = ½x + 2

Look at x = -2 and find the value of y.
what is the y-intercept of (5,8) and (12,36)
Answers
Answer:
The y intercept is (0,-12)
Step-by-step explanation:
You use the slope formula and the slope-intercept form to find the slope m and then the y intercept b.
Answer:
(0, -12)
Step-by-step explanation:
In order to find the y-intercept of the equation y = mx + b ( where m is the slope and b is the y-intercept), we first have to find the slope. We can do this by using the two points given to us.
To find the slope:
The slope is equal to: [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's plug (5,8) and (12,36) into the equation:
[tex]\frac{36 - 8}{12 - 5}[/tex]
Now let's solve for the slope:
36 -8 = 28
12 - 5 = 7
So we get: [tex]\frac{28}{7}[/tex]
Now that we've found the value of the slope, we can put it into the equation:
y = [tex]\frac{28}{7}[/tex]x + b
To find the value of b, we can input the values of one of the given points into the equation and solve for b. Let's use (5,8):
Input the values of x and y into the equation: 8 = [tex]\frac{28}{7}[/tex](5) + b
Multiple [tex]\frac{28}{7}[/tex] by 5: 8 = [tex]\frac{140}{7}[/tex] + b
Divide 140 by 7: 8 = 20 + b
Subtract 20 from both sides of the equation to isolate b:
8 - 20 = 20 - 20 + b
-12 = b
The y-intercept is (0, -12).
