Answers
Answer:
Area of the shaded region = 1.92 cm²
Step-by-step explanation:
From the picture attached,
Area of the shaded region = Area of the sector OMN - Area of the triangle OMN
Area of sector OMN = [tex]\frac{\theta}{360}(\pi r^{2})[/tex]
Here, θ = Central angle of the sector
r = radius of the sector
Area of sector OMN = [tex]\frac{50}{360}(\pi )(6)^2[/tex]
= 15.708 square cm
Area of ΔOMN = 2(ΔOPN)
Area of ΔOPN = [tex]\frac{1}{2}(OP)(PN)[/tex]
Area of ΔOMN = OP × PN
In ΔOPN,
sin(25°) = [tex]\frac{PN}{ON}[/tex]
PN = ONsin(25°)
= 6sin(25°)
= 2.536 cm²
cos(25°) = [tex]\frac{OP}{ON}[/tex]
OP = ONcos(25°)
OP = 6cos(25°)
OP = 5.438 cm
Area of ΔOMN = 2.536 × 5.438
= 13.791 cm²
Area of the shaded region = 15.708 - 13.791 = 1.917 cm²
≈ 1.92 cm²

Answer:
Step-by-step explanation:
Given the system of equations:
2x + 3y = 15
X + 3y = 0
What is x?
2x + 3y = 15
X + 3y = 0 subtract the bottom equation fron the top one
2x - x + 3y - 3y = 15 - 0 see how the 3y - 3y equates to zero
2x - x = 15
x = 15 Now for extra credit what is y?
X + 3y = 0
15 + 3y = 0
15 - 15 + 3y = 0 - 15
3y = -15
3y/3 = -15/3
y = -5

Answers
Answer:
the answer is A prime that is a set containing all the numbers in the universal set that can't be found in A
it is like removing A from the universal set
The resulting sets are not found in the set {4, 5, 7, 8, 10, 13, 14, 16, 17, 19), therefore the choice that describes the set of numbers is (A U B)'

Step-by-step explanation:
Hello There!
Knowing that the sum of the angles in a triangle is 180
we can use this equation to solve for x
180 = 90 + 5x + 2 + 6x
Step 1 combine like terms
90 + 2 = 92
5x + 6x = 11x
now we have
180 = 11x + 92
step 2 subtract 92 from each side
180 - 92 = 88
92 - 92 cancels out
now we have
88 = 11x
step 3 divide each side by 11
11x/11 = x
88/11 = 8
we're left with x = 8
Now we plug in 8 into x for 5x + 2 so we can solve for y
5*8=40
40+2 = 42
Now we can solve for y
the angle measured 42 degrees and the angle labeled y are supplementary angles meaning that the sum of the two angles is 180
so to find y we subtract the given angle (42) from 180
180 - 42 =138 so we can conclude that y = 138
Notes: the little square represents a right angle which has a measure 90 degrees so thats where the 90 came from .

Which of the following represents the distance between the y-intercept and x-intercept of the line whose equation is y = 3x + 12?
1) square root 120
2) square root 160
3) square root 200
4) square root 244
Answers
Answer:
√160
Step-by-step explanation:
For y-intercept, we use y = mx + c. Comparing both, y = mx +c & y = 3x + 12
y intercept = c = 12
Point is (0, 12)
For x intercept, we use y = m(x - d). We have
y = 3x + 12 → y = 3(x - (-4))
Compare both, x intercept = d = - 4
Point is (-4, 0)
Using distance formula,
Distance = √(0-12)² + (-4-0)² = √12²+4²
Distance = √144+16 = √160

Answers
Answer:
27
Step-by-step explanation:
The answer is 27, because 9 x 3 = 27 and the smallest number that is the same is 27.
Hope this helps!
Answer:
27
Step-by-step explanation:
LCM is the least common multiple of one or more numbers. we can find this by finding the factors of 9 and 27.
9, 18, 27, 36, 45, 54
27, 54, 81, 108
since 27 is the smallest factor of both 9 and 27, it is the least common multiple.
