Answer:3
Step-by-step explanation:
<span>8x^2 - 2x - 1 = 0
(2x - 1)(4x + 1) = 0
2x - 1 = 0; x = 1/2
4x + 1 = 0;x = -1/4
answer
</span><span>{-1/4, 1/2}</span>
Answer:
78.10 cm^2
Step-by-step explanation:
The area of the shaded region is the area of the rectangle subtracted from the area of the circle.
area of circle = (pi)r^2
area of rectangle = LW
shaded area = area of circle - area of rectangle
shaded area = (pi)r^2 - LW
shaded area = (pi)r^2 - LW
shaded area = (3.14159)(6 cm)^2 - (7 cm)(5 cm)
shaded area = (3.14159)(36 cm^) - 35 cm^2
shaded area = 113.097 cm^2 35 cm^2
shaded area = 78.097 cm^2
Answer: 78.10 cm^2
150 ones 1.5 hundreds .15 thousands.
Answer:
20
65
95
Step-by-step explanation:
Remark
You have to use a constant to get the ratio so that it will produce angles that will add up to 180. Let that constant = x
Equation
4x + 13x + 19x = 180
Solution
Add the like terms on the left.
36x = 180
Divide both sides by 36
36x/36 = 180 /36
Combine
x = 5
Answer
4x = 20
13x = 65
<u>19x = 95</u>
Total = 180
