In the context of rubiks cube solving the rate at which one can solve a rubiks cube is determined by the number of cubes solved and the time taken
In this question we were told that moira solved a rubiks cube in 3 minutes 30 seconds
Let us convert time total time to seconds
3 minutes 30 in seconds = 3*60+ 30 = 180+30 = 210 seconds
Hence Moira rate = 1 rubiks cube/210 seconds

Is (x + 4) a factor of f(x) = x3 - 2x2 + 5x + 1? Use either the remainder theorem or the factor theorem to explain your reasoning.
Answer:
no
Step-by-step explanation:
By the factor theorem
If (x + h) is a factor of f(x) then f(- h) = 0
Given (x + 4) with h = - 4 , then
f(- 4) = (- 4)³ - 2(- 4)² + 5(- 4) + 1
= - 64 - 2(16) - 20 + 1
= - 64 - 32 - 19
= - 115
Since f(- 4) ≠ 0 then (x + 4) is not a factor of f(x)

Hi
1) For which pair of triangles could ONLY the Side Angle Side postulate (SAS) be used to prove the triangles congruent?
A) Pair A
B) Pair B
9 Pair
D) Pair D
2) For which pair of triangles could either the Side Angle Side postulate (SAS) or Side Side Side postulate (SSS) be used
to prove the triangles congruent?
A) Pair A
B) Pair B
C) Pair C
D) Pair D
Answer:
1) A
2) D
Step-by-step explanation:
1) You can see that both sides are equal and they have only one angle in common
2) This one is a bit more quirky. You have to complete the angles. First, you name the two that are in front of each other because of the vertice. In that way, you can see that they have one side in common (S), then the angle which we just explained (A), and finally another side (S)

A line has a slope of – 4 and includes the points (6,3) and (9,p). What is the value of p?
Answer:
The value of p is -9.
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(p-3)/(9-6)
m=(p-3)/3

A rectangular garden is 40 ft wide and 55 ft long. On a blueprint, the width is 8 in. Identify the length on the blueprint.
Answer:
11
Step-by-step explanation:
First, you set up the proportion for the garden, 40/55 (width/length). Then, right beside it, you set up the proportion for the blueprint garden, 8/x (x because this is the answer we are trying to find). You can then do a scale factor to find the answer and the scale factor is 5 ( because 40 divided by 5 is 8) so you can divide 55 by 5 to get 11!! I hope this helps bro!! :D

Dan made 85% of his free throws. If he took 45 shots how many did he make?
Answer:
38
Step-by-step explanation:
85%=.85
So 45 × .85 = 38.25
38 shots he made.
Hope this helps
Work Shown:
85% = 85/100 = 0.85
85% of 45 = 0.85*45 = 38.25
Rounding to the nearest whole number, we get the result 38
As a check, 38/45 = 0.8444 approximately which converts to 84.44% and that's fairly close to 85%. If we tried 39, then 39/45 = 0.8667 = 86.67% which is a bit too high.
