Answer: (4, 3)
Step-by-step explanation:
The formula for coordinate of the mid point is given as :
Mid point = (
,
)
= 9
= -1
= 9
= -3
Substituting the values into the formula , we have :
Mid-point = (
,
)
Mid-point = (
,
)
Mid - point = ( 4 , 3)

The formula for the volume of a cylinder is pi * radius squared * height, or πr^2h.
To find the radius of the cylinder, take the given diameter (60 cm) and divide it by 2. 60 / 2 = 30 cm.
Now we need to either find the height in centimeters or find the radius in meters. Because a centimeter is 1/100 of a meter, we multiply the radius by 100 to get the radius in meters.
We also must square the radius. So 30 cm multiplied by itself equals 900 cm.
Radius: 900 / 100 = 9 m
We have to square the radius before plugging it into the equation because it would mess up the numbers if we didn't (0.3 m squared is 0.09 m, which is very small).
Now we can plug these values into the formula for the volume of a cylinder.
π * r^2 * h = π * 9 m * 1.7 m = ~48.066 cubic meters
Rounded to two decimal places is 48.07 cubic meters.
The volume of the tree trunk is about 48.07 cubic meters.
Answer:
The correct answer is n = -9.
Step-by-step explanation:
-13n + 20 = -11n + 38
20 = -11n + 38 + 13n Add 13n to both sides
20 = 2n + 38 Combine like terms
20 - 38 = 2n Subtract 38 from both sides
-18 = 2n Simplify
-9 = n Divide both sides by 2
OR
-13n + 20 = -11n + 38
-13n = -11n + 38 - 20 Subtract 20 from both sides
-13n = -11n + 18 Combine like terms
-13n + 11n = 18 Add 11n from both sides
-2n = 18 Simplify
n = -9 Divide both sides by -2

This is a tricky question, all you need to know is that the remainder cannot be a negative number.
So, -50 mod 7 = 6, since -50 /7 = 8 with remainder of 6
