The length of a rectangle is twice its width. If the rectangle's perimeter is 200
inches, what are the length and width of the rectangle?
Step-by-step explanation:
set that width is x
and length become 2X
P = 2×( X+ 2X )
200 = 6 X
X=33. 3
width = 33.3 inch
length = 66. 6 inch

Wendy and Mini earn $49 per week for delivering magazines. Wendy worked for x weeks and earned an additional total bonus of $18. Mini worked for y weeks. Which expression shows the total money, in dollars, that Wendy and Mini earned for delivering magazines
Answer:
(49x + 18) + 49y
Step-by-step explanation:
you woud place the variable (letter) representing the number of weeks they worked by the amount they get paid each week then, you would add to whoever gets an extra amount of money, the y - intercept or in this case the extra 18 dollars one of them gets paid to whoever got paid that amount of extra money. :)
Answer:
C( 49x + 18 + 49y)

Which equation describes the line with slope 5, that contains the point (-2, 4)?
a: y = 5x - 22
b: y = 5x - 2
c: y = 5x + 4
d: y = 5x + 14
Answer:
C
Step-by-step explanation:
Answer:
D.) y=5x+14
Step-by-step explanation:
point slope form: y-y1=m(x-x1)
y1=4, m=5, x1=-2
y-4=5(x+2)
distribute 5
y-4=5x+10
add 4 to both sides
y=5x+14
Find the irrational number between 0.3101 and 0.3333
Answer:
π/10
Step-by-step explanation:
Irrational Numbers
The irrational numbers are identified because, unlike rational numbers, they cannot be expressed as fractions, i.e., as the result of a division between two integers.
If a number is expressed with a limited number of decimals, it's always possible to write it as a rational.
For example, number 1.2319 can be written as 12319/10000.
Even if the number has an unlimited decimal expression, it could be expressed as rational if the decimal part is periodic. Number 2.33333... is rational because it's equivalent to the fraction 7/3.
We need to find an irrational number between 0.3101 and 0.3333.
Any number within the range with unlimited non-periodic decimals will do:
0.3189567363.... is a good example.
We'll choose the number
π/10 since π is a known irrational number and π/10=0.3141592... lies in the given interval.

Answer:
see explanation
Step-by-step explanation:
Substitute the value of x into y = x² and y = [tex]2^{x}[/tex]
x = 1
y = 1² = 1 and y = [tex]2^{1}[/tex] = 2
x = 2
y = 2² = 4 and y = 2² = 4
Thus
x y = x² y = [tex]2^{x}[/tex]

A line with a slope of 8 passes through the points (-1,1) and (0,k). What is the value of k?
Answer:
k = 9
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 8
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)
m = [tex]\frac{k-1}{0+1}[/tex] = k - 1 = 8 ( add 1 to both sides )
k = 9

what is the number
Answer:
[tex]the \: number \: is \: 96[/tex]
Explanation:
[tex]let \: the \: number \: be \: = \: x [/tex]
[tex] \frac{x}{2} + x = 144[/tex]
[tex]2( \frac{x}{2} ) + 2(x) = 2(144)[/tex]

For every $9 invested in company A, $2 is invested in company B. Stacey quizzes her children, Krista and Kevin, about how much money she will invest in company A if she invests $24 in company B. Krista and Kevin used two different methods to arrive at the answer to Stacey's problem. Let's see who found the correct answer and how. You'll answer some questions along the way.
Answer:
$108
Step-by-step explanation:
From the above question, we have the proportion:
Company A/Company B
= $9/$2 = x/x24
The next step is : We Cross Multiply
2x = $24 × $9
x = $24 × $9/2
x = $108
Therefore, she will invest in $108 company A if she invests $24 in company B.
