Find the value of x 105 150 135 125 140 135 x
By using the fact that the sum of the interior angles is 900°, we will find that the value of x is 110.
How to find the value of x?We know that for a figure of N sides, the sum of the interior angles gives:
S = (N - 2)*180°
In this case, we have 7 sides, then the sum of the interior angles gives:
S = (7 - 2)*180° = 5*180° = 900°
Adding the 7 angles we get:
105° + 150° + 140° + x° + 135° + 125° +135° = 900°
790° + x° = 900°
x° = 900° - 790°
x = 110°
The value of x is 110.

You have 41 students three are absent what percentage of students are absent?
Answer:
Step-by-step explanation:
If 41 students is in the roll (total), then
[tex]\frac{3}{41}[/tex] = [tex]\frac{x}{100}[/tex] ⇒ x = [tex]\frac{3*100}{41}[/tex] ≈ 7.3 %
A goat is tired to a pole at the center of a square of length of side 20m. If the rope is 10m long. Calculate the (I) area of the square that can't be grazed by the goat (ii) fraction of grazed portion to the whole area
Answer:
percentage = 78.54%
Step-by-step explanation:
The area of a square of side length x is:
[tex]A_s=x^2[/tex]
The area of a circle of radius r is:
[tex]A_c=\pi r^2[/tex]
The goat is tied to a pole at the center of a square of a side length of x=20 cm.
The area of the square is:
[tex]A_s=20^2[/tex]
[tex]A_s=400~m^2[/tex]
The rope is 10 m long. The goat is able to graze an area of:
[tex]A_c=\pi 10^2[/tex]
[tex]A_c=100\pi~m^2[/tex]
(i)
Since the diameter of the circle (20 m) is equal to the length of the square, the area of the circle is contained in the square and the area of the square not grazed by the goat is:
[tex]A = A_s-A_c=400~m^2-100\pi~m^2[/tex]
[tex]A=100(4-\pi)~m^2[/tex]
Calculating:
[tex]A = 85.84~m^2[/tex]
(ii)
The percentage can be calculated as:
[tex]\displaystyle \frac{A_c}{A_s}*100=\frac{100\pi}{400}*100=25\pi[/tex]
Calculating:
percentage = 78.54%

The quotient of 5 divided A is great than, less than or equal to the quotient of A divided 5?
Answer:
It will depend
Step-by-step explanation:
If a<5 then quotient of 5 divided A is greater than the quotient of A divided 5.
If a=5 then quotient of 5 divided A is equal to the quotient of A divided 5.
If a>5 then quotient of 5 divided A is less than the quotient of A divided 5.

Tito purchased sandwiches and a gallon of milk for himself and his friends. Each
sandwich cost $9. The gallon of milk cost $6. The total cost of the meal was $33.
Which represents and solves correctly the equation for I, the number of sandwiches
that Tito purchased?
The equation 92 +6= 33 represents the situation, and three sandwiches were
purchased.
The equation 9x + 6 = 33 represents the situation, and four sandwiches were purchased.
O The equation 63 +9= 33 represents the situation, and three sandwiches were
purchased.
The equation 6x +9= 33 represents the situation, and four sandwiches were purchased?
Answer:
The equation 9x + 6 = 33 represents the situation, and three sandwiches were purchased.
Step-by-step explanation:
Each sandwich cost $9.
The gallon of milk cost $6.
The total cost of the meal was $33.
Let us represent the number of sandwiches that Tito bought as x
The equation is:
$9 × x + $6 = $33
9x + 6 = 33
Collect like terms
9x = 33 - 6
9x = 27
x = 27/9
x = 3
Hence,
The equation 9x + 6 = 33 represents the situation, and three sandwiches were purchased.

A hot air balloon is descending at a rate of 6.75 feet per second.
What is the change in the balloon's height after 3 1/3 seconds?
The hot air balloon descends 22.498 feet after 3.333 seconds.
How much does a hot air balloon's height decreases?
The situation indicates that the height decrease is directly proportional to time. The distance is equal to the product of speed (v), in feet per second, and time (t), in seconds.
s ∝ t
s = v · t (1)
If we know that v= 6.75 ft / s and t = 3.333 ft, then the change in the height of the hot air balloon is:
s = (6.75 ft / s) · (3.333 s)
s = 22.498 ft
The hot air balloon descends 22.498 feet after 3.333 seconds.

Help please by slope and y- intercept
Answer:
Slope = -3/4Y - intercept = -3Step-by-step explanation:
y = mx + b
mx = slope
b = intercept
1. Simplify the equation
4y = -3x - 12
2. Divide both sides by 4
y = -3/4 x - 3
3. Make a graph
First start at the y-intercept, (0, -3)*
Then, use the pattern -3/4
It is called rise over run.
But, when the slope is negative you have to go down instead of up. So you have to go down 3 and 4 to the right.
Continue that pattern until you get your result.
But when you have to go to the upper part of the graph go up 3 and over 4 to the left.
Continue this pattern.
This also applies to other graphs.
* = remember a y-intercept always has a 0 as the x - coordinate.

h'(e)=
Answer:
[tex]h'(e) = 7^{e-1}\cdot [7\cdot \ln 7+6\cdot e][/tex]
Step-by-step explanation:
Let [tex]h(x) = f(x)^{x}[/tex], the first derivative of the function is found by applying the concept of implicit differentiation:
[tex]h(x) = f(x)^{x}[/tex] (1)
[tex]\ln h(x) = x\cdot \ln f(x)[/tex]
[tex]\frac{h'(x)}{h(x)}=\ln f(x) +\frac{x\cdot f'(x)}{f(x)}[/tex]
[tex]h'(x) = h(x) \cdot \left[\ln f(x)+\frac{x\cdot f'(x)}{f(x)} \right][/tex]
[tex]h'(x) = f(x)^{x}\cdot \left[\ln f(x)+\frac{x\cdot f'(x)}{f(x)} \right][/tex]
[tex]h'(x) = f(x)^{x-1}\cdot [f(x)\cdot \ln f(x)+x\cdot f'(x)][/tex] (2)
If we know that [tex]x = e[/tex], [tex]f(e) = 7[/tex] and [tex]f'(e) = 6[/tex], then [tex]h'(e)[/tex] is:
[tex]h'(e) = 7^{e-1}\cdot [7\cdot \ln 7+6\cdot e][/tex]
In the rectangle below,
Answer:
Step-by-step explanation:
In a rectangle, diagonals are equal and bisect each other
BE = AE
6x - 5 = 2x + 7
6x - 2x - 5 = 7
4x - 5 = 7
4x = 7 + 5
4x = 12
x = 12/4
x = 3
AE = 2x + 7
= 2*3 + 7
= 6 + 7
AE = 13
AC = 13 + 13
AC = 26
m∠EBC = 50
In rectangle, each angle is 90

In rectangle, AB // DC and DB transversal
m∠ECD = m∠ABE { alternate interior angles}
m∠ECD = 40
