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).

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)
Answer:
t = t equals StartFraction f minus v Over a EndFraction z.

The graph shows the amount of money Joe earns each hour he works. Which statement about the graph is not true?
OPTIONS:
F. The graph shows a proportional relationship.
G. The graph shows a nonproportional relationship.
H. The unit rate is $15 hour.
I. The line is straight.
Answer: G
Step-by-step explanation: the rate of change is constant, making it a proportional relationship
a parachutist descends 24 feet in 2 seconds. Express the rate of the parachute's change in high as a unit rate .
Answer:
He's defending 12 ft per second
Step-by-step explanation:
If he descends 24 ft in 2 seconds, then simply divide by 2 to get the rate per second.
Answer: its descending 12 ft per second
step by step explanation : well you know unit rate is used to compare quantities in which the second quantity is one. so you want to divide.
24/ 2= 12

Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across the domain.
0 ≤ y ≤ 80, −0.6875
0 ≤ y ≤ 80, −1.45
0 ≤ x ≤ 55, −1.45
0 ≤ x ≤ 55, −0.6875
The domain of the given function is [0,55] and the average rate of change is -1.45 so option (C) is correct.
What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
The domain is for the independent variable while the range is for the dependent variable.
The domain of a function is the set of input values that the function defines.
The function goes from x = 0 to x = 55 thus 0 ≤ x ≤ 55 will be the domain.
The average slope for (0,80) and (55,0)
⇒ (0 - 80)/(55 - 0) = -1.45
Hence "The domain of the given function is [0,55] and the average rate of change is -1.45".

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°

Answer:
[tex]\frac{100 meters}{x seconds} = \frac{200 meters}{22.4 seconds}[/tex]
Step-by-step explanation:
Answer:
x=11.2
Step-by-step explanation:
cross multiple 100 over x equals 200 over 22.4
100(22.4) = 200x
2,240 = 200x
divide
11.2=x

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

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.
find the slope and ty !!!!!!!

Hector’s service club is raising money by wrapping presents in the mall. The function f(x) = 3x describes the amount of money, in dollars, the club will earn for wrapping x presents. They only have enough wrapping paper to wrap 1000 presents.
Describe the domain of the function.
A. All real numbers such that 1000 ≥ x ≥ 0 (I flipped the problem because I couldn’t find the sign. Really it would be 0 ≥ x ≥ 1000 with the signs facing the other way)
B. All real numbers
C. All whole numbers such that 1000 ≥ x ≥ 0 (I flipped the problem because I couldn’t find the sign. Really it would be 0 ≥ x ≥ 1000 with the signs facing the other way)
