A circle with center O is inscribed in a square with a
perimeter of 40, as shown below. What is the area of the
shaded region?
Answers
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Areas and Volumes.
Area of Shaded region = Area of Square - Area of inscribed Circle.
Radius if circle = 10/2 ==> 5 units
hence,
Area of circle = 25 π units
Area of square = (10)^2 ==> 100 units
hence the area of shaded region = 100 - 25π
==> Area of shaded region = 25 (4 - π)
Correct option is G.)

Answer:
[tex]7x^{25}[/tex]
Step-by-step explanation:
Given sequence: [tex]7x, -7x^5, 7x^9[/tex]
General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]
(where a is the first term and r is the common ratio)
[tex]a_1=7x[/tex]
[tex]a_2=-7x^5[/tex]
[tex]a_3=7x^9[/tex]
To find the common ratio, divide one term by the previous term:
[tex]r=\dfrac{a_2}{a_1}=\dfrac{-7x^5}{7x}=-x^4[/tex]
Therefore, substituting the found values of a and r into the formula:
[tex]\implies a_n=(7x)(-x^4)^{n-1}[/tex]
To find the 7th term, substitute n = 7 into the formula:
[tex]\begin{aligned}\implies a_7 & =(7x)(-x^4)^{7-1}\\ & = (7x)(-x^4)^6\\ & = (7x)(x^{24})\\ & = 7x^{25}\end{aligned}[/tex]

Step-by-step explanation:
Answer:
T (1, 3), U (3, −17), V (−12, −8)
Step-by-step explanation:
To find the image as it is reflected from the preimage across the y-axis, apply the transformation rule, (x,y)→(−x,y), to each of the preimage points.
T(−1,3)→T'(1,3)
U(−3,−17)→U'(3,−17)
V(12,−8)→V'(−12,−8)
Draw lines between the found vertices to construct the reflected figure.
Therefore, the reflection of the figure with vertices T(−1,3), U(−3,−17), and V(12,−8) across the y-axis is the figure with vertices T'(1,3), U'(3,−17), and V'(−12,−8).

Method 1 involves listing out the terms until we reach the seventh one.
squarehexagontrapezoidtrianglesquarehexagontrapezoidtriangleWe see that the trapezoid is term 7.

Method 2 is faster and the one I recommend.
Since the pattern repeats every 4 items, this means we divide by 4 and look at the remainder. Ignore the quotient entirely.
7/4 = 1 remainder 3
The remainder 3 means that the answer is found in term 3, which is the trapezoid.

Answers
The price at which the Nepali bags should be sold in order to make a profit of 140% is $21.02.
What is the price the bags should be sold ?Profit is total revenue less total cost.
The first step to convert Rs. 800 to US dollars: 800 / 105 = $7.62
The second step is to determine the total cost including taxes: 1.15 x 7.62 = $8.76
Selling price = (1 + 1.40) x 8.76 = $21.02

dough and 2 packages of oatmeal cookie dough for a total of $116. Rob sold 9 packages of sugar
cookie dough and 12 packages of oatmeal cookie dough for a total of $318. Find the cost each of
one package of sugar cookie dough and one package of oatmeal cookie dough.
Answers
Answer:
Sugar cookie dough packages cost 14 dollars each, and oatmeal cookie dough packages cost 16 dollars each.
Step-by-step explanation:
Let s equal the cost of a sugar cookie dough package, and o equal the cost of oatmeal cookie dough packages.
6s + 2o = 116
9s+12o = 318
therefore,
18s+6o = 348
18s+24o = 636
Subtracting them, we get -18o = -288, or 18o = 288
Therefore, o = 16, and 6s+32=116, so 6s=84, so s = 14

Answer:

(2, 13)
Step-by-step explanation:
x · y = 26 -------> x = 26/y
y = 1 + 6x
SUB for y
x(1 + 6x) = 26
x + 6x² = 26
SOLVE for x
6x² + x - 26 = 0
6x² + 13x - 12x - 26 = 0
6x(x - 2) 13(x - 2) = 0
(6x + 13)(x - 2) = 0
x = -13/6 or 2
Test x = -13/6 for both equations
Equation 1
-13/6 · y = 26
y = -156/13
y = -12
Equation 2
y = 1 + 6(-13/6)
y = 1 - 13
y = -12
-12 = -12 ✅
Test x = 2 for both equations
Equation 1
2 · y = 26
y = 26/2
y = 13
Equation 2
y = 1 + 6(2)
y = 1 + 12
y = 13
13 = 13 ✅

Since both are even numbers, choose an even number that both divide by.
Like 6
36/6 = 6
90/6 = 15
Can you factor 6 and 15 even more? Yes, by 3
6/3 = 2
15/3 = 5
Can you factor 2 and 5? No, that’s it.
So GCF is 6 * 3 = 18
Lets check:
36/18 = 2
90/18 = 5
Can you factor 2 and 5 even further? No, that’s it

Answers
Step-by-step explanation:
In this case, you input the value of y (y = 6) into the equation ( 2.5(y-x)= 0)
2.5(6-x) = 0
Open the bracket,
(2.5×6)-2.5x= 0
Collect like terms.
2.5x= 2.5×6
Divide both sides by the coefficient of x (2.5)
x = 6
So,
x= 6 is true.

Substituting 6 for x in the equation,
2.5(6-6)= 0
2.5•0 = 0

A 10-speed bike changes gears by moving the chain to different size sprockets on the front and back. The speed at which the bike goes varies directly with the number of revolutions per minute (rpm) you turn the pedals, directly with the number of teeth on the front sprocket, and inversely with the number of teeth on the back sprocket. A standard bike with 70 cm diameter wheels will go about 7.4 kilometers per hour if you pedal 40 rpm in the lowest gear (39-tooth front sprocket, 28-tooth back one). Write an equation expressing km/h in terms of the three independent variables.

The variation is a joint variation, and the equation that relates the three independent variables is [tex]s = 0.18\frac{rf}{b}[/tex]
How to determine the equation in terms of the variables?The direct and the inverse variations from the question can be represented using:
[tex]s = k\frac{rf}{b}[/tex]
Where:
s represents the speed; s = 10k represents the constant of variationr represents the number of revolutions per minutef represents the number of front sprocket teethb represents the number of back sprocket teethFrom the question, we have:
r = 40; f = 39; b = 28
So, we have:
[tex]s = k\frac{rf}{b}[/tex]
[tex]10 = k\frac{40 * 39}{28}[/tex]
Make k the subject
[tex]k = \frac{10 * 28}{40 * 39}[/tex]
Evaluate
k = 0.18
Substitute k = 0.18 in [tex]s = k\frac{rf}{b}[/tex]
[tex]s = 0.18\frac{rf}{b}[/tex]

Step-by-step explanation:
18 + 22 + 15 + 28 + 17 = 100
100 / 5 = 20
So, the mean for the data set: 18, 22, 15, 28, 17 is 20.
18 - 20 = |2|
22 - 20 = |2|
15 - 20 = |5|
28 - 20 = |8|
17 - 20 = |3|
2 + 2 + 5 + 8 + 3 = 20
20 / 5 = 4
So, 4 in is the mean absolute deviation (MAD).

What is the standard deviation of the data? 0.5 1.5 2.0 2.5
Answers
Answer:
0.74
Step-by-step explanation:
The standard deviation of a data set is the sqaure root of the variance, so first we must find the variance. The equation for variance is:
σ² = [tex]\frac{{(x_{1}-[x bar] )}^{2}+...+{(x_{n}-[x bar]) }^{2}}{n}[/tex]
x = number in the data set
xbar = median of the data set
n = number of terms
Plugging in the given values, the equation for the variance of this number set is:
σ² = [tex]\frac{(0.5 - 1.625)^{2} + (1.5 - 1.625)^{2}+ (2.0 - 1.625)^{2}+(2.5 - 1.625)^{2} }{4}[/tex]
Solving:

= [tex]\frac{2.1875}{4}[/tex]
σ² = 0.546875
Since the standard devianation is the sqaure root of the variance, we'll sqaure 0.546875:
[tex]\sqrt{0.546875}[/tex]
