Answer:
4 rational numbers between -1 and 0 are;
(-¼, -½, ¼, ⅜)
Step-by-step explanation:
Rational numbers between two numbers say x and y is given by;
(x + y)/2
Thus;
Rational number between -1 and 0 = (-1 + 0)/2 = -1/2
Rational number between 0 and -1/2 = (-½ + 0)/2 = - 1/4
Rational number between 1 and -1/2 = (-½ + 1)/2 = 1/4
Rational number between 1 and -1/4 = (-1/4 + 1)/2 = ⅜
Thus,4 rational numbers between -1 and 0 are;
(-¼, -½, ¼, ⅜)

A brownie recipe calls for 1 cup of sugar and a cup of flour to make one batch of brownies. To make multiple batches, the equation f is where fis the number of cups of flour and s is the number of cups of sugar represents the relationship. Which graph also represents the relationship? Explain how you know. HURRY !!!!! PLEASE!!!!!!
Answer:
I cant see ths graph but look for one with a positive relationship between flour and sugar meaning that if flour is on one axis sugar should be on the other they should both go up by one every time
Step-by-step explanation:
The graph should say for example at 3 cups of flour that their is 3 cups of sugar. It should look upwards in growth and use whole positive numbers.

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]

What is an equation of a the line through (-1, -4) and parallel to the line 3x+y=5
Answer: y + 4 = -3(x+1)
Step-by-step explanation:
We need to rewrite in form of y=mx+b.
3x+y=5
y = -3x + 5
The slope is -3.
In addition, the slope of two parallel line would be equal, the slope of the line would be -3.
y- y1 = m(x- x1)
y- (-4) = -3(x - -1)
y + 4 = -3(x+1)

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.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
Mary earns $247.25 for gardening.

FV = PV(1 + int)^time PV is present value FV is the future value
PV + Interest = FV
FV - PV = Interest
FV - PV
Interest = [3000(1 + 0.03)^30] - 3000

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:
