The answer to your question is b.
Subtract 9/4 from both sides
3/4x=6 3/4
Multiply them by 4/3
X=9
1) 65% of x=5.2
65/100 of x=5.2
0.65x=5.2
x=5.2/0.65
x=8
2) 44% of x=55
44/100 of x=55
0.44x=55
x=55/0.44
x=125
3) 50% 0f x=7.5
50/100 of x =7.5
0.5x=7.5
x=7.5/0.5
x=15
4) 100% of x =21
100/100 of x=21
1x=21
x=21/1
x=21...........
Answer:
Step-by-step explanation:
The formula for determining the area of a circle is expressed as
Area = πr²
Where
π is a constant whose value is 3.14
r represents the radius of the circle.
Considering the inner layer
radius = 2 millimeters
Area of base = 3.14 × 2² = 12.56 mm²
Considering the outer layer,
Radius = 6 mm
Area of base = 3.14 × 6² = 113.04 mm²
Percent of the area of the base of the outer layer that is the area of the base of the inner layer is
12.56/113.04 × 100 = 11.1%
Answer:
65 degrees
Step-by-step explanation:
y is a right angle and a is 30 degrees. this means that the supplementary engle of x is 45 plus 70 which is 115. 180-115 = 65 degrees.
