A rectangular portrait has an area of 40 square feet it's perimeter is 26 feet what are the dimensions of the portrait?
Answer:
Step-by-step explanation:
Portrait is in the shape of a rectangle.
And the area of a rectangle = Length × Width
Let the length of the portrait = l
And width of the portrait = w
Area of the portrait = lw
lw = 40
l = [tex]\frac{40}{w}[/tex]
Perimeter of a rectangle = 2(Length + width)
Perimeter of the portrait = 2(l + w)
26 = 2(l + w)
l + w = 13 ----------(2)
By substituting the value of 'l' in equation (1) from equation (2)
[tex]\frac{40}{w}+w=13[/tex]
40 + w² = 13w
w² - 13w + 40 = 0
w² - 8w - 5w + 40 = 0
w(w - 8) - 5(w - 8) = 0
(w - 5)(w - 8) = 0
w = 5, 8 feet
From equation (2)
l = 8, 5 feet
Therefore, dimensions of the portrait are (5 feet by 8 feet) Or (8 feet by 5 feet).

Step-by-step explanation:
25x=1252-x exponential equation
Step-by-step explanation:
25x = 1252 - x
We know that in order to solve this equation, we have to move all the x terms to one side and all of the coefficients to the other. So, if we add x to both sides, we get 26x = 1252.
Then, we can divide both sides of the equation by 26 to solve for x, so x≅48.15 or x = 48.153846 repeating.

7/10 would be the probablity
7/10 is the probability that a randomly selected student is a female or a liberal arts major.
Let us determine the number of female students:
15 + 18 + 17 = 50.
Determine the number of students majoring in liberal arts:
20 + 18 = 38.
Determine the number of students who are both female and liberal arts majors: 18.
Add the number of female students and the number of liberal arts majors, but subtract the overlap (students who are both female and liberal arts majors):
50 + 38 - 18
= 70.
Divide the result by the total number of students:
70 / 100
= 7/10.
Hence, the probability that a randomly selected student is a female or a liberal arts major is 7/10.

Answer:
x=75
Step-by-step explanation:
Sum of the interior angles of a trapezoid = 360°
That being said we can calculate the measure of the missing angle (x) by subtracting the given angles (131, 107 and 47) from 360
so x = 360 - 131 - 107 - 47
360 - 131 = 229
229 - 107 = 122
122 - 47 = 75
so x = 75
Additive inverse of 400
Given:
A number is 400.
To find:
The additive inverse of 400.
Solution:
We know that the sum of a number and its additive inverse is 0.
If "a" is number and "b" is its additive inverse, then
[tex]a+b=0[/tex]
Let x be the additive inverse of 400. Then,
[tex]400+x=0[/tex]
Subtract both sides by 400.
[tex]400+x-400=0-400[/tex]
[tex]x=-400[/tex]
Therefore, the additive inverse of 400 is [tex]-400[/tex].

∠ FEG = 50°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
110° is an exterior angle of the triangle, then
5x + 6x = 110
11x = 110 ( divide both sides by 11 )
x = 10
Then
∠ FEG = 5x = 5(10) = 50°

Answer:
220 in²
Step-by-step explanation:
1) use a² + b² = c² to find the missing side length by substituting b with 11 and c with 61 ----- a² + (11)² = (61)²
2) this gets a² + 121 = 3721 after squaring 11 and 61
3) subtract both sides by 121 to try isolating the variable which gets a² = 3600
4) find the square root of 3600 to get the value of a, or the missing side which is 60 in
5) since there are three triangles, divide 60 by 3 which has 20 as the length of each small triangle
6) multiply 20 and 11 to get the area of the each small triangle and get 220 in²
