Answer:
55%
Step-by-step explanation:
44 ÷ 80 = 0.55 = 55%
Answer:
Step-by-step explanation:
For a parabolic equation to NOT contain the point (0,0) it must have a numeric constant independent from both x and y variables, so the general form would be as follows:
Solving the equation for the point (1,1) would give the necessary value for the constant "c" to make the equation valid:
Therefore, the equation that meets both of the required conditions is:
Answer:
10
Step-by-step explanation:
geometric mean theorem :
h = sqrt(pq)
p, q being the segments on the Hypotenuse of the right-angled triangle.
so, x = sqrt(9×10) = 3×sqrt(10)
Answer:
The value of x is 25
Step-by-step explanation:
- <em>A secant is a line that intersects a circle in exactly two points. </em>
- <em>When </em><em>two secants, intersect at a point outside a circle</em><em> then the </em><em>measure of the angle formed between them is one-half the positive difference of the measures of the intercepted arcs</em>
In the given figure
→ In circle O
∵ GB and GD intersect it at points F, B, and E, D
∴ GB and GD are secants of circle O
∵ GB and GD intersect outside the circle O at point G
∵ They intercepted arcs EF and BD
→ By using the rule above
∴ m∠G = (m arc BD - m arc EF)
∵ m arc BD = m arc BC + m arc CD
∵ m arc BC = 35° and m arc CD = 100°
∴ m arc BD = 35 + 100 = 135°
∵ m arc EF = x
∵ m∠G = 55°
→ Substitute them in the rule above
∴ 55 = (135 - x)
→ Multiply both sides by 2 to cancel the fraction
∵ 110 = 135 - x
→ Subtract 135 from both sides
∴ -25 = -x
→ Divide both sides by -1
∴ 25 = x
∴ The value of x is 25
10% of 55 is 5.5
You could divide 55 by 10 to get 5.5 or multiply 55 by the decimal representation of 10% which is .1
.1 x 55 = 5.5
55 / 10 = 5.5
