79 hours will it take for one person to harvest the entire strawberry patch.
What is the conversion of the unit?The same property is expressed using a unit conversion but in a distinct unit of measurement. For instance, time can be stated in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other length unit instead of miles.
Finding the strawberry patch's area in square meters and dividing it by the amount that one person can harvest in an hour will give us the total number of hours needed to solve this issue.
The strawberry patch's measurements must first be changed from decameters (dam) to meters.
1 decameter (dam) = 10 meter
Strawberry patch length in meters = 1.7 dam * 10 m/dam = 17 m.
The strawberry patch width in meters = 1.4 dam x 10 m/dam = 14 m.
The strawberry patch's area is therefore:
Area of strawberry patch = length × width = 17 m × 14 m = 238 m²
We must now determine how long it will take one individual to pick 3 m² of strawberries, in hours. We can calculate this by dividing the patch's overall area by the area that a single individual can select in an hour:
= a number of hours needed to harvest the complete patch.
The total harvesting time is = 79.33 hours nearly equal to 79
Therefore, it would take one person 79 hours to gather the complete strawberry patch.

If f (x) = √2x + 4 and g(x) = 1/2(x-4)², what is f(g(x))?
If f (x) = √2x + 4 and g(x) = 1/2(x-4)² then the function is f(g(x)) = √2 * (x-4) * √[1 + 2/[(x-4)²]]
What is function?
An expressiοn, rule, οr law in mathematics that specifies the relatiοnship between an independent variable and a dependent variable (the dependent variable). In mathematics and the sciences, functiοns are fundamental fοr cοnstructing physical relatiοnships.
This relatiοnship is typically represented as y = f(x), οr "f οf x," and y and x are related such that fοr each value οf x, there is a specific value οf y. This means that f(x) can οnly have οne value fοr a given x. In set theοry jargοn, a functiοn cοnnects an element x tο an element f(x) in anοther set. The set οf x values is referred tο as the dοmain οf the functiοn, and the set οf f(x) values prοduced by the values in the dοmain are referred tο as the range οf the functiοn.
[tex]f(g(x)) = \sqrt{[2g(x) + 4]}[/tex]
Now we can substitute the expression for g(x):
[tex]f(g(x)) = \sqrt{[2(1/2(x-4)²) + 4]}[/tex]
We can simplify this expression by first expanding the square in the brackets:
[tex]f(g(x)) = \sqrt{[2(x-4)^2 + 4]}[/tex]
Then we can factor out the 2 from the square:
[tex]f(g(x)) = \sqrt{[2(x-4)²] * √[1 + 2/[(x-4)²]]}[/tex]
Simplifying further:
[tex]f(g(x)) = \sqrt{2 * (x-4) * \sqrt{[1 + 2/[(x-4)²]}]}[/tex]
Therefore, [tex]f(g(x)) = \sqrt{2 * (x-4) * \sqrt{[1 + 2/[(x-4)²]}]}[/tex]

Shannon wants to buy a car but only has half as much money as she needs. If Shannon deposits the money into a savings account that earns 10.99% interest compounded quarterly, how long will it take for her money to double?
Round your answer to the nearest month.
it will take Shannon about 80 months for her money to double if she deposits it into a savings account that earns 10.99% interest compounded quarterly.
Shannon's funds will double in value during the following period of time, according to the quarterly compound interest formula:
[tex]A = P(1+r/n)^{nt}[/tex]
where n is the number of times interest is compounded each year, r is the yearly interest rate, P is the principal amount, A is the amount after t years, and t is the amount of time in years.
Shannon currently has P/2 dollars, which is half of what she needs. Finding t when A = 2P will help us determine how long it will take for her money to double.
We are aware that n = 4 and r = 10.99%. (since interest is compounded quarterly). Solving for t using these values as input results in:
[tex]2P = P/2(1 + 0.1099/4)^{(4t) }\\4 = (1 + 0.1099/4)^{(4t)} log(4) \\= 4t log(1 + 0.1099/4)^ t = log(4)/(4 log(1 + 0.1099/4))[/tex]
t ≈ 6.7 years
Rounding this to the nearest month gives:
t ≈ 80 months
Therefore, it will take Shannon about 80 months for her money to double if she deposits it into a savings account that earns 10.99% interest compounded quarterly.

if an ice block 10 centimeters wide, 10 centimeters high, and 20 centimeters long was melted, how much would it raise the water level in a tank that is 100 centimeters long by 40 centimeters wide?
Step-by-step explanation:
Volume of ice = 10 X 10 X 20 = 2000 cm^3
tank volume increase will be the same
100 x 40 x HEIGHT = 2000
Height = 2000/ ( 100 X 40) = .5 cm height increase
The melting of the ice block would raise the water level in the tank by approximately 0.5 centimeters. This can be answered by the concept of Volume
To calculate the amount of water that would be displaced by the ice block, we need to first find its volume, which is 10 x 10 x 20 = 2000 cubic centimeters. Since 1 cubic centimeter of water has a mass of 1 gram, the mass of the ice block would be 2000 grams or 2 kilograms.
When the ice block melts, it will turn into water and occupy the same volume, which would displace an equal amount of water in the tank. The volume of the tank is 100 x 40 x h, where h is the increase in water level. Setting the volume of the ice block equal to the increase in the water level, we get:
2000 = 100 x 40 x h
h = 0.5 centimeters
Therefore, the melting of the ice block would raise the water level in the tank by approximately 0.5 centimeters.

Find the 61st term of the following arithmetic sequence7,16,25,34
Answer:
61st term = 547
Step-by-step explanation:
The formula for the nth term of an arithmetic sequence is
[tex]a_{n}=a_{1}+(n-1)d[/tex], where a1 is the first term, n is the term position (e.g., 1st or 61st) and d is the common difference.
We already know that a1 = 7 and the n = 61. We can find the common difference by finding the difference of any two consecutive terms with the smaller term being subtracting from the larger:
Thus, if we use 7 and 16, our common difference (d) is:
d = 16 - 7 = 9
Now, we can simply plug in everything to the formula to find the 61st term:
[tex]a_{61}=7+(61-1)*9\\ a_{61}=7+60*9\\ a_{61}=7+540\\ a_{61}=547[/tex]

At the baseball game the Kacanich family purchased 3 hot dogs and 2 cheeseburgers and paid $31.25. The Nisbet family purchased 5 hot dogs and 2 cheeseburgers and paid $41.75. Write and solve a linear system to find the cost of each hot dog and each cheeseburger.
Let x be the cost of a hot dog and y be the cost of a cheeseburger. Then we can set up the following system of equations:
3x + 2y = 31.25
5x + 2y = 41.75
We can solve for one of the variables by subtracting the first equation from the second:
5x + 2y - (3x + 2y) = 41.75 - 31.25
2x = 10
x = 5
Substituting x = 5 into either of the equations above gives:
3(5) + 2y = 31.25
15 + 2y = 31.25
2y = 16.25
y = 8.125
Therefore, a hot dog costs $5 and a cheeseburger costs $8.125.
