Question:
The model below represents an equation.
2 long x tiles and 3 square y tiles = 3 long x tiles
Which represent like terms in the model of the equation?
Answer:
2 long x tiles and 3 long x tiles are like terms
Step-by-step explanation:
Given
2 long x tiles and 3 square y tiles = 3 long x tiles
Required
Identify the like terms
Represent long with a and square with b.
So, we have:
2a x and 3b y = 3a x
and, as used here means addition
So:
[tex]2a x + 3b y = 3a x[/tex]
Collect like terms
[tex]3by = 3ax - 2ax[/tex]
[tex]3by = ax[/tex]
See that 3ax and 2ax are evaluated without any barrier.
This means that they are like terms

Solve the following systems of equation: y = 6x 4x + y = 7
Answer:
y=21/5, x=7/10
Step-by-step explanation:
Substitute y=6x
4x=6x=7
Simplify 4x+6x
10x=7
isolate x for 10x=7:
10x=7
Divide both sides by 10:
10x/10=7/10
Simplify:
x=7/10
For y=6x substitute x=7/10
y=6*7/10
Convert element to fraction:
6/1*7/10
Cross- cancel common factor:2
3/1*7/5
Multiply fractions:
3*7/1*5
Multiply the numbers:3*7=21
=21/5
y=21/5
The solutions to the systems of equations are:
y=21/5,x=7/10

The length of each side of the base of a square pyramid is 20 m. The pyramid is 30 m tall.
The volume of the pyramid is ___ cubic meters.
Answer:
4000 [tex]m^{3}[/tex]
Step-by-step explanation:
V = 1/3(Bh) where B is the area of the base and h is the height of the pyramid
B = 20(20) = 400 h = 30
V = 1/3(400)(30) = 4000 [tex]m^{3}[/tex]

For each carbon-14 atom, there are approximately 10^12 carbon-12 atoms. This ratio is constant in each organism. The carbon-12 remains constant but the carbon-14 decays. Suppose a piece of wood is analysed, and it contains 10^14 carbon-12 atoms and 40 carbon-14 atoms.
1) Determine how many carbon-14 atoms were present in the wood when it died.
2) Use the half life of carbon-14 atoms to obtain a function to model the number N of carbon-14 atoms present in the wood (t) years after it died
Answer:
1) There are 100 carbon-14 atoms in the wood when it died
2) A function that models the number 'N' of carbon-14 atoms present in the wood (t) years after it died is presented as follows;
[tex]N = 100 \times \left (\dfrac{1}{2} \right )^{\dfrac{t}{5,730} }[/tex]
Step-by-step explanation:
The given parameters are;
The number of carbon-12 for each carbon-14 atom ≈ 10¹² carbon-12 atoms
The number of carbon-12 in the piece of wood = 10¹⁴ carbon-12 atoms
The number of carbon-14 in the piece of wood = 40 carbon-14 atoms
The number of carbon-12 in an organism = Constant
The number of carbon-14 in an organism = Decays
1) Given that the number of carbon-12 in an organism is constant, and there are 10¹² carbon-12 atoms per each carbon-14 atom, therefore, we have;
The number of carbon-12 atoms in the wood when it died = 10¹⁴ carbon-12 atoms
The number of carbon-14 atoms in the wood when it died = (10¹⁴ carbon-12 atoms)/(10¹² carbon-12 atoms/(carbon-14 atom)) = 100 carbon-14 atoms
The number of carbon-14 atoms in the wood when it died = 100 carbon-14 atoms
2) The half life of a radioactive isotope is given by the following formula;
[tex]N(t) = N_0 \cdot \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{\frac{1}{2} }} }[/tex]
The half life of carbon-14 atoms, [tex]t_{\frac{1}{2} }[/tex] ≈ 5,730 years
N₀ = The amount of carbon-14 present in the wood when it died = 100 carbon-14 atoms
Therefore, we have;
The number, N, of carbon-14 atoms present in the wood (t) years after it died is given as follows;
[tex]N = 100 \times \left (\dfrac{1}{2} \right )^{\dfrac{t}{5,730} }[/tex]

Answer: Hi i hope your doing good well the answer is 55
Step-by-step explanation: Angles one and two are complementary. So we know the sum of their measures is 90 degrees. So, to find the measure of angle two, subtract the measure of angle one from 90 degrees. We substitute in the given value of the measure of angle one, which is 35 degrees. Subtracting, we find that the measure of angle two equals 55 degrees.

We can calculate the probability of picking a red marble by:
- adding all the marbles together
- then subtract the amount of red marbles by the number found previously.
2 + 3 + 5 = 10
10 - 5 = 5
5 is what of 10?
5 is 50% of 10.
50% means 0.5 out of 1.
Your answer is 0.5.
Hope this helps. Have a nice day.

Part A: The Sun produces 3.9 ⋅ 1033 ergs of radiant energy per second. How many ergs of radiant energy does the Sun produce in 1.55 ⋅ 107 seconds? Express your answer in scientific notation and show your work. (5 points)
Part B: Which is the more reasonable measurement of the distance between the tracks on a CD:
1.6 ⋅ 10−3 mm or 1.6 ⋅ 103 mm? Justify your answer. (5 points)
Answer:
A. The answer is 165.85. B. The best answer is 1.435 ·103 because while they both are really small for a rail road track that one is bigger. the final answer for that is 147.805mm.
Step-by-step explanation:
(3.9 x 10³³) / 1 = X / (2.45 x 10⁵) .
Solve that proportion for ' X ' in the usual way.
If you can't remember how to solve a proportion, then
THAT's what you have to go look up. It's much more
important to you right now than how much energy the
sun is putting out.
7.4 x 10⁴ mm is the same size as about 243 feet !
If the tracks on a DVD were that far apart, there would not be
room for very many tracks on a DVD. That's not reasonable.
If the tracks are 7.4 x 10⁻⁴ mm apart, then there are about
34,000 tracks in a stripe that's 1-inch wide. I have no idea
how they do this, but it's certainly more reasonable than the
other choice. Hope this helps! Can you please give me Brainleist?

w = 5
l = 5
2 (2 · 5 + 2 · 5 + 5 · 5)
Using PEMDAS, we have:

A class was conducting a series of probability experiments.
Which set of events would have an equally like chance of occurring?
A
spinning a spinner with 3 sections and tossing a coin.
B
rolling a six-sided cube and drawing 6 marbles out of a bag.
С
tossing a coin and choosing an odd number between 1 and 7
D
drawing 1 card out of 25 cards and choosing a letter out of the alphabet.
Set of events " rolling a six-sided cube and drawing 6 marbles out of a bag " have an equally like chance of occurring.
Option B is correct.
Probability:Probability of series of experiments shown below;
A. When spinning a spinner with 3 sections then probability of one section is [tex]\frac{1}{3}[/tex] .
When tossing a coin, then probability of getting head or tail is [tex]\frac{1}{2}[/tex]
So that, set A has not equally like chance of occurring.
B. When rolling six-sided cube, probability of getting one number is [tex]\frac{1}{6}[/tex]
When one marble is drawn out of 6 marble in a bag, then probability is [tex]\frac{1}{6}[/tex]
Therefore, set B has equally like chance of occurring.

Answer:
45.5625
Step-by-step explanation:
The pattern seems to be x + (x/2) = y where x is the previous number and y is the next number.
4 + (4/2) = 6
6 + (6/2) = 9
therefore we continue the pattern. In doing so we get:
30.375 + (30.375/2) = 45.5625
