if mary earns $247.25 for gardening. if she worked 21.5 hours this month, then how much did she earn per hour?
Mary earns $11.5 per hour.
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.
Mary worked for 21.5 hours.
So, Mary earns per hour
= 247.25 / 21.5
= $11.5

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.

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]

11.16 in^2
2.8 in^2
50.24 in^2
Answer:
11.16in^2
Step-by-step explanation:
Area of a sector = theta/360 * πr²
Area of a sector = 80/360 * 3.14*4²
Area of a sector = 8/36 * 50.24
Area of a sector = 401.92/36
Area of a sector = 11.16in^2

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:

John took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4.70 plus $2.50 per mile. The total fare was $24.70, not including the tip. How many miles was the taxi ride?
Answer:
8
Step-by-step explanation:
You can solve this by creating a linear equation.
Slope: 2.50
Y-intercept: 4.70
y=2.50x+4.70
Since we know that the total fare was 24.70 we can plug it into the y.
24.70=2.50x+4.70
Now solve for the equation.
20=2.50x
8=x
So he went 8 miles with the taxi.
Total number or mile taxi run is 8 miles.
Given that;
Pick up charge = $4.7
Charges per mile = $2.5 per mile
Total fare = $24.7
Find:
Number of mile taxi ride
Computation:
Total fare = Pick up charge + [Total number or mile taxi run][Charges per mile]
24.7 = 4.7 + [Total number or mile taxi run][2.5]
[Total number or mile taxi run][2.5] = 24.7 - 4.7
[Total number or mile taxi run][2.5] = 20
Total number or mile taxi run = 20 / 2.5
Total number or mile taxi run = 8 miles
