Answer: 78.5
Step-by-step explanation:
Formula: A=pi*r^2 or Area = 3.14*radius squared (by two)
A = 3.14*10^2
A = 3.14*100
A = 314
Divide it by 4, because it's a quarter of the circle: A = 314/4
A = 78.5
Answer: 78.5

Which equation represents a line that passes through (2, -0.5) and has a slope of 3? Oy - 2 = 3(x+ -0.5) 0 y 3= 2(x + 0.5) 0y + 7 = 3(x - 2) Oy + 7 + 2(x - 3)
Answer:
y=3x-6.5
Step-by-step explanation:
y-y1=m(x-x1)
y-(-0.5)=3(x-2)
y+0.5=3x-6
y=3x-6-0.5
y=3x-6.5
The slope of a line indicates the measure of the steepness and the direction of the line. The slope of any line can be calculated using any two distinct points lying on the line. The equation is y = 3x-6.5. The correct option is D.
What is equation of a line?The equation of a line is an algebraic form which represents the set of points, which together form a line in a coordinate system. The equation of line is a linear equation with a degree of one. It can be formed with the help of the slope and a point on the line.
The equation of a line passing through the point and slope is given as:
(y - y₁) = m (x - x₁)
(y - -( 0.5)) = 3 ( x - 2)
(y + 0.5) = 3 (x - 2)
(y + 1/2) = 3 (x - 2)
or
y + 0.5 = 3x - 6
y = 3x - 6.5
Thus the correct option is D.

Answer:
Angle MJK = 64°
Step-by-step explanation:
In ∆MJL & ∆LJK,
JL= JL ...(common side)
Angle JML = Angle JKL ....( each 90°)
MJ = JK ....( Both measures 7)
Hence, by SAS criteria, ∆ MJL = ∆ LJk
.°. by C.P.C.T , ∠MJL = ∠LJK = 32°
Also,
∠MJK = ∠MJL+∠LJK
∠MJK = 32°+32°

Answer:
n = 945 / 135
Step-by-step explanation:
n = total seats / number of seat in each section
n = 945 / 135
n = 7

Answer:
The missing angle is 24 degrees
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
x+156 = 180
Subtract 156 from each side
x+156-156 = 180- 156
x = 24

30. Work out the next two terms, giving your answers as fractions decimals or percentages. The sequence below is linear. 0.6 75% 9 10 \ (2 marks)
Answer:
The next two terms are: 1.05 and 1.20
Step-by-step explanation:
Given
[tex]Sequence: 0.6, 75\%, 9/10[/tex]
Required
Write out the next two terms
Since it is a linear sequence; first, we calculate the common difference (d)
[tex]d = 75\% - 0.6[/tex] or [tex]d = 9/10 - 75\%[/tex]
Express as decimals
[tex]d = 0.75 - 0.6[/tex] or [tex]d = 0.9 - 0.75[/tex]
[tex]d = 0.15[/tex] (in both cases)
So, we add 0.15 to 9/10, to get the next term
[tex]Next = 9/10 + 0.15[/tex]
[tex]Next = 0.9 + 0.15[/tex]
[tex]Next = 1.05[/tex]
Add 0.15 to 1.05, to get the next term
[tex]Next = 1.05 + 0.15[/tex]
[tex]Next = 1.20[/tex]
The next two terms are: 1.05 and 1.20
