1. 83 square inches
2. 7.065 square centimeters
Step-by-step explanation:
Hey there!
In order to find the area of the shaded region of the rectangle, you need to first find the area of the whole shape
The dimensions are 10 and 16 and if you multiply them together, you get 160
This means that the area of the whole shape is 160
Now they are asking for the area of the shaded shape, so we need to find the area of the white rectangle, and then subtract that area from 160
The dimensions for the white rectangle is 11 and 7
This means that the area of the white rectangle is 77
Now what we need to do is subtract 77 from 160
160-77=83
So the area of the shaded region is 83 square inches
Now to get to the second question
We need to find the area of the quarter circle
In order to find this, we need to first find the area of the whole circle, then divide that by 2
They gave us the radius already which makes it a lot easier (the radiues is 3)
All we need to do is input 3 into the formula for the area of a circle
[tex]\pi r^2[/tex]
In this case, since they are telling us to use 3.14 as pi, the equation would look like this:
[tex]3.14*3^2[/tex]
This can be simplified to [tex]3.14*9[/tex] which is equal to 28.26
So this is the area of the whole circle
But the question is asking for the area of a quarter of that circle
So what we need to do is divide 28.26 by 4 which is 7.065
So the area of the quarter circle is 7.065 square centimeters

If a student wants to multiply by 8 they can?
A. Multiply by 2 three times
B Multiply by 2 four times
C Multiply by 4 twice
D Multiply 2 and multiply by 4 and add them together
Answers
Hello Brainly user,
A. Multiply by 2 three times if you want to multiply by 8.
Proof:
For example, if you want to multiply 2 by 8 --> 2x8 then you can just do 2x2 = 4 4x2 = 8 8x2 = 16.
TO CHECK:
You can do 8x2 = 16.
Hence, this answer is 100% correct.

Answer:
[tex]x=0, \dfrac{\pi}{6},\dfrac{5\pi}{6},\pi \:\sf(for\:the\:given\:interval)[/tex]
Step-by-step explanation:
given interval [0, 2π) = 0 ≤ x < 2π
[tex]2\sin^2(x)=\sin(x)[/tex]
subtract sin(x) from both sides:
[tex]\implies 2\sin^2(x)-\sin(x)=0[/tex]
factor:
[tex]\implies \sin(x)[2\sin(x)-1]=0[/tex]
[tex]\sin(x)=0[/tex]
[tex]\implies x=0 \pm2 \pi n, \pi \pm2 \pi n[/tex]
[tex]\implies x=0, \pi \:\sf(for\:the\:given\:interval)[/tex]
[tex]2\sin(x)-1=0[/tex]
[tex]\implies \sin(x)=\dfrac12[/tex]
[tex]\implies x=\dfrac{\pi}{6} \pm2 \pi n, \dfrac{5\pi}{6} \pm2 \pi n[/tex]
[tex]\implies x=\dfrac{\pi}{6},\dfrac{5\pi}{6}\:\sf(for\:the\:given\:interval)[/tex]
Final solution:
[tex]x=0, \dfrac{\pi}{6},\dfrac{5\pi}{6},\pi \:\sf(for\:the\:given\:interval)[/tex]

Step-by-step explanation:
The angle measures for the triangle is 60, 60 and 60.
What is Triangle?A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
We have,
The measure of three sides are 6 ,6 and 6.
Now, we know a triangle whose three sides are equal is called as Equilateral Triangle.
Also, three angles are Equal.
Using Angle Sum property
x + x + x = 180
3x= 180
x= 60
Thus, the measure of three angles are 60, 60 and 60.

Answers
The area of the rectangle is the product of its base and height
The height of the rectangle is 4x - 2 units
How to determine the height?The given parameters are:
Area = 4x^2 - 2x
Base = x
The area of the rectangle is:
Area = Base * Height
This gives
4x^2 - 2x = x * Height
Divide through by x
4x - 2 = Height
Rewrite as:
Height = 4x - 2
Hence, the height of the rectangle is 4x - 2 units

Answers
Answer:

Step-by-step explanation:
ON = OA + AN
AN = 2/5AB
AB = 5b-4a
AN = 2b - 8/5a
ON = 4a - 8/5a +2b
ON = 12/5a+2b
OP = k(12/5a+2b)
OP = OA + AP
AP = x(AM)
AM = 5/2b-4a
OP=4a-4ax+5/2bx
OP=4a-4ax+5/2bx and OP=12/5ak+2bk
Coefficients of A
4-4x=12/5k
k=(20-20x)/12
Coefficients of B
5/2x=2k
k=5/4x
(20-20x)/12 =5/4x
20=35x
x=4/7
k=5/4 * 4/7 = 5/7
OP=k(ON)
OP = 5/7
PN = 2/7
OP:PN = 5:2
