The two dot plots below compare the forearm lengths of two groups of schoolchildren:
Based on the visual inspection of the dot plots, which group appears to have the longer average forearm length?
A. Group A, because a child in the group has the least forearm length of 10 inches.
B. Group A, because four children have a forearm length longer than 12 inches.
C. Group B, because no child in the group has a forearm length longer than 12 inches.
D. Group B, because five children in the group have the least forearm length of 10 inches.

Answer:
Let [tex]\pi[/tex] represent 3.14
SA = 2[tex]\pi[/tex]r^2 + 2[tex]\pi[/tex]rh
SA = 2[tex]\pi[/tex](5)^2 + 2[tex]\pi[/tex](5)(12)
SA = 2[tex]\pi[/tex](25) + 2[tex]\pi[/tex](60)
SA = 50[tex]\pi[/tex] + 120[tex]\pi[/tex]
SA = 50(3.14) + 120(3.14)
SA = 157 + 376.8
SA = 533.8inch^2
Therefore the surface area of the cylinder is 533.8 square inches.
Answer: Let represent 3.14SA = 2r^2 + 2rhSA = 2(5)^2 + 2(5)(12)SA = 2(25) + 2(60)SA = 50 + 120SA = 50(3.14) + 120(3.14)SA = 157 + 376.8SA = 533.8inch^2

find the measure of MNI. please help! i’ll give you brainlist!
Answer:
[tex]m\angle MNI = 135^{\circ}[/tex]
Step by step explanation:
[tex]\text{The exterior angle of a triangle = sum of two opposite interior angles.}[/tex]
[tex]~~~~~~\angle MNI = \angle LMN + \angle MLN\\\\\implies 19x+2=(15x-12)+6x\\\\\implies 19x +2 = 21x-12\\\\\implies 21x -19x = 12+2\\\\\implies 2x = 14\\\\\implies x=\dfrac {14}2\\\\\implies x = 7\\\\\text{So,}~ m\angle MNI = 19(7)+2=135^{\circ}[/tex]

This is because for a number to be divisible by 9 all the digits should add up to a number divisible by 9. Since they already do you just put a 0.

Answer:
√689 ≈ 26.2 leagues
Step-by-step explanation:
For the purpose of calculating the distance between the marked points, the line is considered to be the hypotenuse of a right triangle. The horizontal distance between the points is one leg of the triangle, and the vertical distance is the other leg. The Pythagorean theorem relates these distances.
Pythagorean relationThe Pythagorean theorem relates right triangle sides 'a' and 'b' to hypotenuse 'c' with the formula ...
c² = a² +b²
Taking the square root, we have an expression for 'c' in terms of 'a' and 'b'.
c = √(a² +b²)
Application to distanceThe horizontal distance between the points is the difference of their x-coordinates:
a = x2 -x1 = 2 -(-18) = 20
The vertical distance between the points is the difference of their y-coordinates:
b = y2 -y1 = -10 -7 = -17
When we square these numbers, we find their signs to be irrelevant.
c = √(a² +b²) = √(20² +(-17)²) = √(400 +289) = √689
c ≈ 26.249
The distance between the given points is about 26.2 leagues.

1. 3 units up
2. 3 units down
3. 3 units to the right
4. 3 units to the left
The x value is the same, the y value is different,
Y is the up and down movement.
Moving from -8 to -5 is an upward move of 3 units.
Answer: 1, 3 units up.
(Will give 25 points!) Solve the system of linear equations by substitution. 1/2x + 1/4y = 2 x + y = 1
B: if x is 6, what is y?
Answer:
Step-by-step explanation:
4x + y = x + 3y
4x - x = 3y - y
3x = 2y
if x = 6 then
3*6 = 2y
18 = 2y
y = 9

A square pyramid on top of a rectangular prism. The rectangular prism has a length of 4 meters, width of 4 meters, and height of 4 meters. The square pyramid has triangular sides that have a height of 3 meters and side length of 5 meters. Compare the surface area of the composite figure to the surface area to the combined surface areas of the figures if they were separated. The composite surface area would be the surface area of the rectangular prism plus the surface area of the square pyramid considered separately. You should not count the pyramid’s as part of the composite figure’s surface area.
Answer:
The square pyramid by itself has a surface area of 55 meter[tex]s^2[/tex].
The rectangular prism by itself has a surface area of 96 meter[tex]s^2[/tex].

ABCD is a rectangle in which AD = (2x + 1) cm and DC = (3x - 2) cm. PQRS is a trapezium in which PQ is parallel to SR, PQ = (x + 2) cm, SR = (5x − 8) cm and the shortest distance between PO and SR is (4x – 11) cm. The area of ABCD is twice the area of PQRS. Write down an equation in x to represent this information and show that it simplifies to 18x²89x + 68 = 0.
