What is a rectangle?A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. A rectangle is always a parallelogram and a quadrilateral but the reverse statement may or may not be true.
The area of a rectangle with side lengths of 6/8 meter and 4/10 meter is,
Area of rectangle = 6/8 meter × 4/10 meter
= 24 / 80 meters²
= 6 /20 meters²
= 0.3 meters²
Hence, The area of a rectangle with side lengths of 6/8 meter and 4/10 meter is 0.3 meters².

Find the missing value.

The correct answer is 6
Step-by-step explanation:
x/10=3/5
then cross multiply
it will now give
5x=30
x=6
if 251 base x =100, find x
If [tex]251_x\equiv100_{10}[/tex], then this translates to the equation
[tex]251_x = 2x^2 + 5x + 1 = 100[/tex]
Solve for [tex]x[/tex].
[tex]2x^2 + 5x = 99[/tex]
[tex]2\left(x^2 + \dfrac52 x\right) = 99[/tex]
[tex]2 \left(x^2 + \dfrac52 x + \dfrac{25}{16}\right) - \dfrac{25}8 = 99[/tex]
[tex]2 \left(x + \dfrac54\right)^2 = \dfrac{817}8[/tex]
[tex]\left(x + \dfrac54\right)^2 = \dfrac{817}{16}[/tex]
[tex]x + \dfrac54 = \pm \dfrac{\sqrt{817}}4[/tex]
[tex]x = \dfrac{-5\pm\sqrt{817}}4[/tex]
though it is a bit unusual (but not entirely out of the question) to have an irrational base number system.
In case you meant [tex]100_2[/tex] on the right side, then [tex]100_2 = 2^2 = 4_{10}[/tex], so that

Answer:
12.0 to 3 dig digs You must include the 0 to get 3 significant figures.
Step-by-step explanation:
Comment
This is a Pythagorean Problem. Use the formula
c ^2 = a^2 + b^2
Givens
a = 8 - 7 = 1 cm
b = 12 cm
c = ?
solution
c^2 = 1^2 + 12^2
c^2 = 1 + 144
c^2 = 145 Take the square root of both sides
√c^2 = √145
c = 12.04
c = 12.0 to 3 sig digs.
He length of the hypotenuse of a right triangle is 24 inches. if the length of one leg is 8 inches, what is the approximate length of the other leg? 16.0 inches 18.4 inches 22.6 inches 25.3 inches
Answer:
22.6
Step-by-step explanation:
a^2 + b^2 = c^2 We know one of the legs and the hypotenuse. The hypotenuse must be c. The leg that we do know can be a or b. It is our choice. I am going to let it be a
8^2 + b^2 = 24^2 Plug in the numbers that I know
64 + b^2 = 576 Square the numbers that I know
b^2 = 512 Subtract 64 from both sides
b = 22.6 Put this in your calculator to find the square root and round.

The picture is attached below.
The value of n is 31.
The median is the line connecting the vertex and its midpoint on the opposite side of the triangle.
The intersection of all 3 medians of the triangle is called the centroid.
As we know centroid divides the median in the ratio of 2:1.
In the given picture,
Medians of triangle △ABC are AM, BL, and CK.
So the centroid of the triangle is O.
Given that KC= 108
As the centroid O divides the line KC in 2:1.
Let OC=2x
KO= X
As KC= KO+OC
⇒ 108= x+2x
⇒ 3x=108
⇒ x=108/3
⇒ x=36
Then OC= 2x= 2*36= 72
As given in the question OC= 2n+10
putting the value of OC in above equation
⇒ 72= 2n+10
⇒ 2n= 72-10
⇒ 2n=62
⇒ n=62/2

What are the trig values?Given the equation and interval.
tanθ = -3, [ π/2 < θ < π ]
First, we use the definition of tangent to determine the known sides of the unit circle right triangle.
Note that; the quadrant determines the sign of each values.
tanθ = opposite / hypotenuse
We can use Pythagoras theorem to find the hypotenuse of the unit circle right triangle as the opposite and adjacent sides are known.
Hypotenuse = √( opposite² + adjacent² )
Hence, we have;
Hypotenuse = √( [3]² + [-1]² )
Hypotenuse = √( 9 + 1 )
Hypotenuse = √10
1) To find sinθ
sinθ = opposite / hypotenuse
sinθ = 3/√10
We simplify
sinθ = 3/√10 × √10/√10
sinθ = 3√10 / 10
[tex]sin \theta = \frac{3\sqrt{10} }{10 }[/tex]
2) cosθ
cosθ = adjacent / hypotenuse
cosθ = -1 / √10
Simplify
cosθ = -1 / √10 × √10/√10
cosθ = -√10 / 10
[tex]cos\theta = -\frac{\sqrt{10} }{10}[/tex]
3) cotθ
cotθ = adjacent / opposite
cotθ = -1 / 3
[tex]cot\theta= -\frac{1}{3}[/tex]
4) secθ
secθ = hypotenuse / adjacent
secθ = √10 / -1
[tex]sec\theta=-\sqrt{10}[/tex]
5) cscθ
cscθ = hypotenuse / opposite
cscθ = √10 / 3
[tex]csc\theta= \frac{\sqrt{10} }{3}[/tex]
Therefore, the appropriate values are; [tex]sin \theta = \frac{3\sqrt{10} }{10 }[/tex], [tex]cos\theta = -\frac{\sqrt{10} }{10}[/tex], [tex]cot\theta= -\frac{1}{3}[/tex], [tex]sec\theta=-\sqrt{10}[/tex] and [tex]csc\theta= \frac{\sqrt{10} }{3}[/tex].
