Jacey likes to do jumping jacks while eating jelly beans. She can eat about 41 jelly beans in 10 minutes. If she has eaten 1,231 jelly beans how many minutes has she been doing jumping jacks?
Answer:
About 300 minutes
Step-by-step explanation:
She can eat 41 jelly beans in 10 minutes and she has eaten 1231
You need to divide 1231 by 41 (then you will know how many sets of 41 jelly means she ate)
It will give you 30.024390...
and if she at this many sets of 41 and each 41 is 10 minutes,
then you have to multiply 30 by 10
you get about 100 minutes

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

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

Is 0.875 irrational or rational and why?
How do you do a negative power?
Answer:
A negative exponent is defined as the multiplicative inverse of the base, raised to the power which is opposite to the given power. In simple words, we write the reciprocal of the number and then solve it like positive exponents. For example, (2/3)-2 can be written as (3/2)2.

please mark me brainliest9. 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]

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

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.

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
