Answer:
D) 50,000
Step-by-step explanation:
5×10^4 is equivalent to 50,000. This is because, when solved, 5×10^4 gives a result of 50,000 as shown below:
10^4= 10*10*10*10= 10,000
5*10= 50
So, 5×10^4= 10,000*50 = 50,000
Formula to find the mid-point is
.
We need to find the mid-point of HG where H(0,0) and G(2a,0). So, now we can plug in x1=0, y1=0, x2=2a and y2=0 in the above formula to get the answer. So, mid-point of HG is,
.
=
=(a,0).
So, mid-point of HG is (a, 0).
You will set it up so that the two equations are equal to each other.
2,200 * (2.31 * 10^x) = 1.05 * 10^y
Then depending on what you have learned you either plug in each value and check, or solve it mathmatically.
The steps for solving mathmatically:
Distribute the 2,200.
5082 * 22000^x = 1.05 * 10^y
Next divide both sides by 1.05
4840 * 20952.4^x = 10^y
I don't know if that is to the power of y or times y?
Answer:
Step-by-step explanation:
Compoud interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. the formula is:
Step-by-step explanation:
Let length is x and breadth is y.
The formula for the area and the perimeter of a rectangle is given by :
A = xy
P = 2(x+y)
Here, A = 8 mi² and P = 16 miles
Putting all the values,
xy = 8
y=8/x ......(1)
2(x+y) = 16
x+y = 8 .....(2)
Put equation (2) in equation (1) as follows :
When we solve, we get :
x = 6.82 miles, 1.17 miles
Put the value of x in equation (1)
When x = 6.82 miles,
y = 8/6.82
y = 1.17 miles
When x = 1.17 miles,
y = 8/1.17
y = 6.82 miles
Hence, the dimension of the field is 6.82 miles and 1.17 miles.
