Write 9 1/100 as a decimal number
Answer:
9.01
Step-by-step explanation:
9 1/100 = 9 + 1/100
1/100= 1 divded by 100
=9+0.01=9.01
the value of 9 1/00 in decimal, is 9.01
What is Simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given a number 9 1/100
in decimal, we can also write it as
9 1/100 = 9 +1/100
=> 9 1/100 = 9.01
therefore, in decimal the value of 9 1/100 is 9.01.

What is 2x+2y=8 in standard form
Answer:
x+y=4
Step-by-step explanation:
2x+2y=8
By taking out 2 from 2x+2y as common terms, we get
2(x+y)=8
Now, by dividing both sides by 2, we get
2(x+y)/2=8)2
x+y=4
9. Use Structure Point K is of the way from |(4,-5) to L(0, -7). a. What are the coordinates of Kif n = 4? b. What is a formula for the coordinates of K for any n?
Dividing the segments, it is found that:
a) The coordinates of K if n = 4 are [tex](5,-frac{9}{2})[/tex]b) [tex]K - J = \frac{1}{n}(J - L)[/tex]----------------------------
The endpoints are [tex]J(4,-5)[/tex] and [tex]L(0,-7)[/tex].Point K is (x,y).Since point K is [tex]\mathbf{\frac{1}{n}}[/tex] of the way from J to L, it means that:[tex]K - J = \frac{1}{n}(J - L)[/tex]
And this is the answer to option b.
----------------------------
Option a:
If [tex]\mathbf{n = 4}[/tex], it has that:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
This is applied to find both the x-coordinate and the y-coordinate of K.
----------------------------
The x-coordinate of K is x.The x-coordinate of J is 4.The x-coordinate of L is 0.Thus:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
[tex]x - 4 = \frac{1}{4}(4 - 0)[/tex]
[tex]x - 4 = 1[/tex]
[tex]x = 5[/tex]
----------------------------
The y-coordinate of K is y.The y-coordinate of J is -5.The y-coordinate of L is -7.Thus:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
[tex]y - (-5) = \frac{1}{4}(-5 - (-7))[/tex]
[tex]y + 5 = \frac{2}{4}[/tex]
[tex]y = \frac{1}{2} - 5[/tex]
[tex]y = \frac{1}{2} - \frac{10}[2}[/tex]
[tex]y = -\frac{9}{2}[/tex]
The coordinates of K if n = 4 are [tex](5,-frac{9}{2})[/tex]

ends when a total of
101 points have been scored.
How many point did Mark
have
Answer:
94
Step-by-step explanation:
When a player reaches 101 points, they win. So that means that Mack reached 101 points. Since his opponent was seven points behind, we can subtract 7 from 101 to find Mark's, that is Mack's opponent's, score:
[tex]101-7=94[/tex]
Therefore, we can safely conjecture that Mark scored 94 points.

Explain how you get this answer
9514 1404 393
Answer:
= 0.108
Step-by-step explanation:
Use a calculator or long division.
When using long division, it is convenient to move the decimal points in both numbers to the right 2 places. This makes the divisor an integer, so makes it easier to keep track of appropriate place value in the quotient.
0.189/1.75 = 18.9/175 = 0.108
The average yearly cumulative rainfall in Tucson by month is shown in the graph below. Does this
graph represent cumulative rainfall as a function of the day? Why or why not? What is the average
annual cumulative rainfall in Tucson? What is the approximate average rainfall in December? During
which month is average rainfall the greatest? How do you know?
Answer:
The average annual cumulative rainfall is [tex]1[/tex] inch per month.
During month of August average rain fall is greatest because slope in this month is maximum.
Step-by-step explanation:
The graph does not represent cumulative rainfall as a function of day.
Because they have average all values for month Total cumulative rainfall is [tex]12[/tex] inches.
Total period is [tex]12[/tex] month
So average annual cumulative rainfall is
[tex]$12 / 12=1$[/tex] inch per month
Average rain fall in month of December= (average cumulative rainfall in December[tex])-([/tex]average cumulative rainfall in November)
[tex]=12-11[/tex]
[tex]$=1$[/tex] inch
During month of August average rain fall is greatest because slope in this month is maximum.

What is -1 7/8 + -2 1/4? Please explain why and a step by step :).
9514 1404 393
Answer:
-4 1/8
Step-by-step explanation:
Many people find it easier to factor out -1, then do the addition. The fractions need a common denominator before they can be added. A suitable denominator that is a multiple of both 4 and 8 is 8.
The fraction 1/4 = (1/4)(2/2) = (1·2)/(4·2) = 2/8.
__
So, the problem can be rewritten as ...
-(1 7/8 +2 2/8)
= -((1+2) +(7/8 +2/8))
= -(3 +9/8)
The fraction 9/8 is an improper fraction equal to 8/8 +1/8 = 1 1/8. Then the sum is ...
-(3 +1 1/8) = -4 1/8

The perimeter of a rectangle is 82 meters. If the length of the rectangle is 20 meters more than the width
of the rectangle, find its length and width.
Answer:
30.5 meters
10.5 meters
Step-by-step explanation:
x = length
y = width
x = y + 20
2x + 2y = 82 (the perimeter of a rectangle)
using the first equation as substitute in the second equation we get
2×(y + 20) + 2y = 82
2y + 40 + 2y = 82
4y = 42
y = 42/4 = 21/2 = 10.5 meters
x = y + 20 = 21/2 + 20 = 21/2 + 40/2 = 61/2 = 30.5 meters

Solve the equation z^4+4z^2+16=0
Answer:
As this is a quartic equation, we should expect four roots (although some may end being repeated). Notice also that the equation is symmetrical, which suggests that there might be an element of symmetry in the answer.
First, as this equation is a quadratic in terms of z2 , we can use our formula for finding the roots of a quadratic equation to give the value(s) of z2 . [If you have a problem seeing this, use the substitution y=z2 , and you get a quadratic in y .]
z2=−4±42−4×1×16√2×1=−4±16−64√2
=−4±−48√2=−2±12−−√i=−2±23–√i
=4(−12±3√2)i
=4(cos(2kπ3)+isin(2kπ3)) , where k∈1,2
=4e2kiπ3
As this is the value of z2 , whereas we want z , we need to take the square roots of both sides
z=4–√ekiπ3+nπ , where n∈0,1
=2e(k+3n)iπ3
=2cis((k+3n)iπ3)
As we have two values of k and two values of n , this gives us four solutions.
Writing these angles in terms of degrees, we have: 60, 120, 240 and 300
Evaluating, we end up with the four solutions
z=1±3–√i∪z=−1±3–√i
You can substitute z^2 = x,
Then you get x^2+4x+16=0
Step-by-step explanation:
z=1±3–√i∪z=−1±3–√i
You can substitute z^2 = x,
Then you get x^2+4x+16=0
Then you can use classical x1,2 = (-b +- √[b^2–4ac])/2a
X1,2=(-4+-√[16–16*4])/2
After you solve that you substitute back z^2 = x
