Answer:
8/27 ≈ 29.6%
Step-by-step explanation:
Two of the six faces are B, which means four of the six faces are not B.
The probability of rolling not B three times is:
P = (4/6)^3
P = (2/3)^3
P = 8/27
P ≈ 29.6%
Answer: the width of the rectangle
= 31feet.
Step-by-step explanation:
Perimeter of a triangle = 2( l + b)
let the width = xfeet
The length = 2x feet.
Substitute for this in the equation above,
2( 2x + x ) = 186
2(3x) = 186
Divide by 2 through
3x = 93
Divide by 3
x = 31feet. Therefore, the width of the rectangular = 31feet.
Check.
Since the length is twice the width,
L = 31 x 2
= 62feet.
Put that into the formula above
2( 62 + 31 )
2 x 93
= 186 which is the perimeter of the rectangle.
That means a down bow, it means you move your hand away from the violin, away/down :D Hope it helped!
Answer:
1: 1/2
2: 1
3: Assuming 2 medium triangles = 1 large triangle, then 2
Step-by-step explanation:
1: 2 small triangle makes 1 square. So, if we divide the area of the square (1 square unit) by 2 because 2 small triangles make 1 square, we get 1/2.
2: 2 small triangles makes 1 medium triangle, so using the above logic, 1/2 X 2 = 1.
3: Assuming 2 medium triangles = 1 large triangle, then the same thing applies. medium * 2 = 2
The solutions to this triangle are:
- 7.9
- 44.1 degrees
- 83.7 degrees
<h3>How to solve for the triangle</h3>
Using the law of cosine we would have
a²=b²+c²-2bc cos A
a² =100+49-2(10)(7)cos 52
This would give us
=149 -140 x (0.6157)
=62.82
We take the square root of 62.82 =
7.93 or 7.9
We have to use the sine law to find the other side
7.9/sin 52=10.057
10.06=7/sin C
such that
sin C = sin(0.6958)
=44.1°
10.06=10/sin B
cross multiply
sin B=10/10.06
= sin⁻¹0.9940
Then B = 83.7°
