the perimeter of a rectangle is 40m. one of the lengths or the sides is 5m. find the lengths of the other 3 sides.
The perimeter of a rectangle is 40m and one side of it is 5m. What is the length of the other side using an equation?
Perimeter of the rectangle =2(l+ b)=40m
If one of its side b=5, then l = (40/2)-5
= 20–5
= 15 m Therefore
Length= 15 cm
Breadth =5 cm
Answer:
perimeter means the total distance of all sides of a shape. Rectangle has 2pairs of 2 sides with the same length. If one is 5 the other pair would be 5. So 40-5-5 would be the total of the second pair , 30. 30/2=15. So there's 2 sides with 5m each, and another 2 sides with 15m each

Answer: 5:2
Step-by-step explanation:
Well, you are going to find a number they both divide by in this case it is 2
10/2=5
4/2=2
Now when rewriting your numbers make sure to put what comes first first
5:2
5 and 2 can not be divided evenly anymore so your final answer is 5:2

Answer:
(x, y, z) = (-8 2/7, -10, -7 3/7)
Step-by-step explanation:
A graphing calculator or matrix solver can find the solution easily. It is ...
(x, y, z) = (-8 2/7, -10, -7 3/7)
__
You can find y by subtracting the second equation from the third:
(2x -y +z) -(2x -3y +z) = (-14) -(6)
2y = -20
y = -10
Putting this value into the first equation and either of the others gives ...
x -3z = 14
2x +z = -24
Subtracting twice the first of these from the second gives ...
(2x +z) -2(x -3z) = (-24) -2(14)
7z = -52
z = -52/7 = -7 3/7
x = 14 +3(-7 3/7) = -8 2/7
So, the solution is (x, y, z) = (-8 2/7, -10, -7 3/7).

The price of a video game was reduced from 60 to 45 . By what percentage was the price of the video game reduced
Answer:
The price was reduced from $60 to $45 - So the price was reduced by $15. $15 is what percent of the original price of $60? Percentages can be expressed as fractions or decimals. For example, 30% is the same as 0.30 or 30/100.
The number N(t) of people in a community who are exposed to a particular advertisement is governed by the logistic equation. Initially, N(0) = 200,and it is observed that N(1) = 400. Solve for N(t) if it is predicted that the limiting number of people in the community who will see the advertisement is 20,000. (Round all coefficients to four decimal places.)n(t) = ?
9514 1404 393
Answer:
n(t) = 20,000/(1 +99e^(-0.7033t))
Step-by-step explanation:
One way to write the logistic function is ...
n(t) = L/(1 +a·e^(-kt))
where L is the maximum value and parameters 'a' and k depend on boundary conditions.
Here, we have n(∞) = L = 20,000 and n(0) = L/(1+a) = 200. We also have n(1) = L/(1+a·e^-k) = 400.
Solving for 'a', we get ...
n(0) = 20000/(1+a) = 200
20000/200 -1 = a = 99
Solving for k, we get ...
n(1) = 20000/(1 +99e^-k) = 400
20000/400 -1 = 99e^-k = 49
e^-k = 49/99
k = -ln(49/99) ≈ 0.7033
So, the desired function is ...
n(t) = 20000/(1 +99e^(-0.7033t))

A shoe store costs 1800 dollars a month to operate. The average wholesale cost of each pair of shoes is 25 dollars, and the average price of each pair of shoes is 65 dollars. How many pairs of shoes must the store sell each month to break even?
Answer: 45
Step-by-step explanation:
The store has to sell
45
pairs of shoes.
Explanation:
The store has a base cost of
$
1800
, the cost per pair of shoes is
$
25
. Each pair of shoes is sold for
$
65
, therefore the profit per pair of shoes is
$
65
−
$
25
=
$
40
The formula for calculating the amount that needs to be sold would look like this;
40
x
=
1800
To determine the value of
x
, we take this formula;
x
=
1800
40
x
=
45
Therefore, the store needs to sell
45
pairs of shoes to break even.
What is the following quotient?
Answer: Choice B) [tex]\frac{5\sqrt{11}+5\sqrt{3}}{8}\\\\[/tex]
==========================================
Work Shown:
[tex]\frac{5}{\sqrt{11}-\sqrt{3}}\\\\\\\frac{5(\sqrt{11}+\sqrt{3})}{(\sqrt{11}-\sqrt{3})(\sqrt{11}+\sqrt{3})}\\\\\\\frac{5\sqrt{11}+5\sqrt{3}}{(\sqrt{11})^2-(\sqrt{3})^2}\\\\\\\frac{5\sqrt{11}+5\sqrt{3}}{11-3}\\\\\\\frac{5\sqrt{11}+5\sqrt{3}}{8}\\\\\\[/tex]
This shows why choice B is the answer.
---------------
Explanation:
In the second step, I multiplied top and bottom by [tex](\sqrt{11}+\sqrt{3})[/tex]This is so we can apply the difference of squares rule in step 3. The difference of squares rule is (x-y)(x+y) = x^2-y^2.In step 4, the square roots cancel out with the squaring operation. The two operations are inverses of one another, which is why they cancel.So in general, if the denominator is [tex]\sqrt{a}-\sqrt{b}[/tex] and you want to rationalize the denominator, then you should multiply top and bottom by [tex]\sqrt{a}+\sqrt{b}[/tex]. The same applies in reverse as well.
This leads to the denominator becoming [tex](\sqrt{a}-\sqrt{b})(\sqrt{a}+\sqrt{b}) = (\sqrt{a})^2-(\sqrt{b})^2 = a-b[/tex]
Keep in mind that [tex]a \ge 0[/tex] and [tex]b \ge 0[/tex]
