Reginald has to put fertilizer on his yard. The bags of fertilizer cost $4.79 and cover 3500 square feet. Reginald's yard is a rectangle that measures 427 ft by 231 ft. How much will he spend on fertilizer?
Answers
He'll spend 138.91 dollars.
First multiply 427 and 231 to find out how much square feet you need to cover. Then divide the number by 3500 to see how many bags of fertilizer you need. Since there is a remainder, he'll have to buy another bag. Then, multiply the number of bags needed with the price of each bag to get the amount of money spent.

The statement that best describes the effect of replacing the graph of f(x) with the graph of f(x) - 3 is; B) The graph shifts 3 units down.
what is graph?
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it. If we know that the function crosses x axis at some, then for some polynomial functions, we have those as roots of the polynomial.
The parent function is function of x and we the translated function is in the form f(x)-3.
Transformation Rule state that if the parent function is f(x) and if we subtract some constant 'a' in f(x) then the function will move down by 'a' units.
Thus, from the transformation rule, we can conclude that f(x) graph will shift down by 3 units.
Therefore, the correct option is; B) The graph shifts 3 units down.

1. First, divide 82 by 100, since this is what you would have originally gotten with the ratio.
82 ÷ 100 = 0.82
2. Then multiply it by 50 (since this is how many questions were on the test)
0.82 × 50 = 41 <----- (the number of questions answered correctly)
3. Now that you have the two numbers you need, you can assemble the ratio.

Answer:
x = 57
Step-by-step explanation:
Median is the number that is halfway mark. If we are given a data, first we need to arrange them in ascending order and take the middle value. That is called median.
If we have odd number of data, we can easily find the middle value.
For instance, 1, 2, 3, 4, 5 here the number of data = 5 which is odd number.
The middle number is 3.
Therefore, median is 3.
If we have even number of data, we have to take middle two values, add them then divide by 2.
In this case, we are given even number of data
30, 45, x, 100
4 data which is even number of data.
Median is given as 51, we need to find the value of x.
The middle two numbers are 45 and x, we have to add them and divide by 2
Median = [Given: median = 51]
51 =
Multiplying both sides by 2, we get
51*2 = 45 + x
102 = 45 + x
Subtract 45 in both sides, we get
102 - 45 = 45 -45 + x
x = 102 -45
x = 57
In this case, the values are "45" and "x". If we pretend that we know the value of the variable "x" (for example we will pretend that x is 55), then we should have an equation that looks like this: (45+55) ÷ 2 = [median]. What this equation is doing is adding the two closest values to the median (45 and 55) and dividing it by 2, the number of values we are averaging. Now we can solve this equation and simplify it to 100 ÷ 2 which is 50, our median.
So if they give us the median instead of the x value, then we can rewrite the equation to fit your request: (45+x) ÷ 2 = 51. Now we can solve for x:
1. Multiply by 2
(45+x) = 102
2. Subtract 45
x = 57
The x value for your question is 57.

since you are summing the powers of 1/5, this converges
(1/5 < 1)
it's equal to 1/(1-1/5)
=1/(4/5) = 5/4
for geometric series, the sum is always
x = 1/(1-r)
where r is the ratio of successive terms.
if you set the sum equal to x:
x = 1+r+r^2+r^3...
and multiply each term by r
rx= r+r^2+r^3+....
then subtract
x-rx = 1+r-r+r^2-r^2+r^3-r^3+....
x-rx = 1
x(1-r)=1
x=1/(1-r)
