You work as a lab assistant. Each morning you are responsible for grouping the correct number of test tubes for each experiment that will be conducted that day. Today 40 test tubes will be used for 12 experiments. The first two experiments will require 4 test tubes each. Six of the experiments will require 3 test tubes each, and 2 of the experiments will require 2 test tubes each. Each of the two remaining experiments will use exactly the same number of test tubes.
Which calculation is appropriate to perform first when determining the number of test tubes that will be used for each of the two remaining experiments?
A) 10/2
B) 40 − 30
C) 40 − 12
D) 2(4) + 6(3) + 2(2)
Answer: D
Step-by-step explanation:
In total 40 test tubes are required for 12 experiments.
The first two experiments will require 4 test tubes for each.
Hence, there will be a requirement of = 8 test tubes.
Six experiments require 3 test tubes each.
Hence, these 6 experiments will take 18 test tubes.
Other 2 experiments will take 2 test tubes.
Here, = 4 test tubes will be required.
Till now a total of (8 + 18 + 4) = 30 test tubes have been used.
The remaining number of test tubes is (40 - 30) = 10.
The remaining experiments require test tubes.
The first calculation to perform is 2(4) + 6(3) - 2(2).

What is the slope of the line?
Answer:
2/3
Step-by-step explanation:
Step 1
(1,2) (4,4)
First we are going to pick two point on the line.
Step 2
(y2-y1) / (x2-x1)
(4-2) / (4-1)
in the first set we label x as x1 and y as y1, then we do the same with the other set but with x turning into x2 and y turning into y2. We then plug them into the equation.
Step 3
(2)/(3)
or
2/3
Now we solve what is in the parentheses (4-2) is 2, and (4-1) is 3. We then take away the parentheses and have 2/3. keep 2/3 as a fraction, do not change it to a decimal.
When finding the common denominator between fractions, which value can be helpful, GCF or LCM?

Find the next three terms of an arithmetic sequence 58 , 63 , 68 , 73 . find the next three terms
and show all your work how did u get it and the formula and ty
Answer:
78 - 83 - 88
Step-by-step explanation:
If you minus all the numbers together, you get
73 - 68 = 5
68 - 63 = 5
63 - 58 = 5
1) So, 73 + 5 = 78
2) Next is 78 + 5 = 83
3) Last, 83 + 5 = 88

The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a, over time, t.
Which is an equivalent equation solved for t?
t = t equals StartFraction f minus v Over a EndFraction z.
t = t equals StartFraction f minus a Over v EndFraction z.
t = a(f – v)
t = v(f – a)

Find the value of x in the triangle below.
Answer:
x = 50°
Step-by-step explanation:
Sum of Angles in a Triangle: 180°
All angles in a triangle must add up to 180°.
Step 1: Set up equation
x + 70° + 60° = 180°
Step 2: Solve for x
Combine like terms: x + 130° = 180°Subtract 130 on both sides: x = 50°Answer:
50°
Step-by-step explanation:
Step 1:
x + 70° + 60° = 180° Sum of a Δ
Step 2:
x + 130° = 180° Combine Like Terms
Step 3:
x = 180° - 130° Subtract 130° on both sides
Answer:
x = 50°
