Answer:
12.5
Step-by-step explanation:
If an isosceles right triangle as the length of the equal sides is a , then the length of the hypotenuse will be a2–√ (using pythogoras theorem.
Hence the perimeter will be a+a+a2–√=a(2+2–√)
Hence the equal sides of the triangle in question has the length of a=5
Area of the triangle = 12∗Height∗Base
=12∗5∗5=12.5

Step-by-step explanation:
A shoe store pays 1980$ a month for rent. The average profit on each pair of men's shoes is $25, and the average profit on each pair of wemons shoes is $65. They usually sell 3times as many pairs of wemons shoes as men's.How many pairs of shoes of each type of shoe must the store sell each month to pay the rent?
Answer:
Number of men's shoes = x = 9 shoes
Number of women's shoes = y = 27 shoes
Step-by-step explanation:
A shoe store pays 1980$ a month for rent. The average profit on each pair of men's shoes is $25, and the average profit on each pair of wemons shoes is $65. .How many pairs of shoes of each type of shoe must the store sell each month to pay the rent?
Number of men's shoes = x
Number of women's shoes = y
The system of equations is given as:
$25 × x + $65 × y = $1980
25x + 36y = $1980..... Equation 1
They usually sell 3times as many pairs of wemons shoes as men's
y = 3x
25x + 65y = $1980..... Equation 1
25x + 65(3x) = 1980
25x + 195x = 1980
220x = 1980
x = 1980/220
x = 9 shoes
y = 3x
y = 3(9)
y = 27 shoes
Number of men's shoes = x = 9 shoes
Number of women's shoes = y = 27 shoes
2(6x+5)=58

Determine whether the function is linear or nonlinear? Help
Answer:
linear
Step-by-step explanation:
If it is linear, for each unit increase in x, there should be a constant change in y.
x=1, y=5
in x=2, we expect y to increase by 5 units, so 5+5 = 10, which is right.
x=3, expect 5 units increase, and we do see that as 10+5 = 15.
x=4, expect 5 unit increase, and 15+5 =20 so we see that
this is linear function, if nonlinear then we would see different changes of y for each unit increase of x.

Last week, the number of type 2 cabinets produced exceeded twice the number of type 1 cabinets produced by 20. If x is the number of type 1 cabinets produced and y is the number of type 2 cabinets produced, the system of equations that represents this situation is x + y = 110 and y = 2x + 20.?
Step-by-step explanation:
Let x is the number of type 1 cabinets produced and y is the number of type 2 cabinets produced.
The total no of cabinets are 100
Equation will be : x+y = 110
We can write it as : y = 110-x ...(1)
Last week, the number of type 2 cabinets produced exceeded twice the number of type 1 cabinets produced by 20.
Equation will be : y = 2x + 20 ...(2)
Put the value of y from equation (1) into equation (2).
110-x = 2x + 20
Combining like terms,
110-20 = 2x+x
90 = 3x
x = 30
Put the value of x in equation (1) :
y = 110-30
y = 80
Hence, there are 30 cabinets of type 1 and 80 cabinets of type 2.

Alarger number is 2 more than 4 times a smaller number. The larger number is also 8 more than 2 times the smaller number. 4x+2 y 2x+8 What is the value of the smaller number in the mathematical problem?
Answer:
the value of the smallest number is 3
Step-by-step explanation:
The computation of the value of the smaller number is shown below:
Given that
y = 4x + 2
y = 2x + 8
Now equate these two equations
4x + 2 = 2x + 8
4x - 2x = 8 - 2
2x = 6
x = 3
Hence, the value of the smallest number is 3
The same is to be considered
Answer:
The value number is 3

Solving Polynomials (PLZ HELP!! BRAINLIEST IF RIGHT)
Answer:
[tex]x=\frac{2}{5}[/tex]
Step-by-step explanation:
[tex]5x^3-2x^2+5x-2=0\\x^2(5x-2)+(5x-2)=0\\(x^2+1)(5x-2)=0\\Hence,\\Either\ (x^2+1)\ should\ equal\ zero, or (5x-2)\ should\ be\ null.\\Lets\ try\ each\ on\ seperately:\\(x^2+1)=0\\x^2=-1\\x=\sqrt{-1}\\As\ \sqrt{-1}\ is\ not\ a\ real\ number,\ we\ can\ exclude\ it\ as\ a\ solution.\\Hence,\\(5x-2)=0\\5x=2\\x=\frac{2}{5} \\Thats\ your\ answer.[/tex]
Answer:
x = [tex]\frac{2}{5}[/tex] , x = ± i
Step-by-step explanation:
Given
5x³ - 2x² + 5x - 2 = 0 ( factor the first/second and third/fourth terms )
x²(5x - 2) + 1(5x - 2) = 0 ← factor out (x - 2) from each term
(5x - 2)(x² + 1) = 0
Equate each factor to zero and solve for x
5x - 2 = 0 ⇒ 5x = 2 ⇒ x = [tex]\frac{2}{5}[/tex]
x² + 1 = 0 ⇒ x² = - 1 ⇒ x = ± [tex]\sqrt{-1}[/tex] = ± i
The polynomial is of degree 3 and has 3 roots, 1 real and 2 complex, that is
x = [tex]\frac{2}{5}[/tex] ← real root
x = ± i ← complex roots

The Micro Devices Company earned 3,632,859,678 dollars this year. 2,459,632,852 dollars were earned last year. Which is the best estimate of how many more dollars were earned this year than last year?
Answer:
$1,173,226,826
Step-by-step explanation:
The estimate of the increase in dollars earnings is the difference between this year's earnings and last year's earnings. In other words, the increase in earnings is the excess of current year's earnings over last year's earnings as computed below:
increase in earnings=this year's earnings-last year's earnings
this year's earnings=$3,632,859,678
last year's earnings=$2,459,632,852
increase in earnings=$3,632,859,678-$2,459,632,852
increase in earnings=$ 1,173,226,826

You want to take 10 lessons at a swim club. You can pay a membership fee of $20 plus a fee per lesson. You can also decide no to pay a membership fee. In that case, the fee per lesson is $3 more. Is there any lesson fee for which these two plans cost the same?
Answer:
x = 1
Step-by-step explanation:
Plan A: 20 + 10x
Where, x = fee per lesson
Plan B: $3 × 10 lessons = $30
Equate plan A and plan B
Plan A = Plan B
20 + 10x = 30
10x = 30 - 20
10x = 10
x = 10/10
= 1
x = 1
