Answer:
i think it is 50.27
Step-by-step explanation:
area=R pie ^2
radius = 4
1. The equation of the line is:
y=-2x/3 + 5
2. The equation of the line in slope intercept form is:
y=3x+5
1. Given:
we have two points:
(-3,7) = (x₁,y₁)
(9,-1) = (x₂,y₂)
equation of the line is:
y - y₁ = m(x-x₁)
₁first calculate slope m = y₂-y₁/x₂-x₁
m = -1-7/9-(-3)
m = -8/12
m = -2/3
now, y - 7 = -2/3 (x-(-3)
y-7=-2/3(x+3)
y-7=-2x/3-2
y=-2x/3-2+7
y=-2x/3 + 5
hence equation of the line is y=-2x/3 + 5
2. Given two points:
(2, 11) and (4, 17)
(2, 11) = (x₁,y₁)
and (4, 17) = (x₂,y₂)
slope intercept form:
y=mx+c
we need to calculate the m value:
m = 17-11/4-2
m = 6/2
m=3
now substitute in the given form:
y - 11 = 3(x-2)
y-11=3x-6
y=3x-6+11
y=3x+5
Hence we get the required answer.

Answer with explanation:</h2>
In the given diagram , here are two circles .
The center of larger circle is at C and the center of the small circle is at B.
Also, the small circle is intersecting the bigger one at two points i.e. at A and D.
Since the distance from the center of the circle to its boundary is the radius of the circle.
∴ Length of AB is same as length of BD [ ∵Radii of same circle are congruent.]
Part A
The number of members in the equal-size groups will be the Greatest Common Divisor of the numbers 20 and 25. That number is 5. There are several ways to find this number. One way is to look at the prime factors of 20 and 25:
20 = 2*2*5
25 = 5*5
The largest factor common to both is 5.
There will be 5 students in each group.
Part B
The number of groups is the number of students divided by the size of the group.
There will be 20/5 = 4 groups of sixth graders.
There will be 25/5 = 5 groups of seventh graders.
Step-by-step explanation:
Let the larger no be = a
Difference of the numbers = a - 32
As per the question;
(a + 32) = 5(a - 32)
⇒ a + 32 = 5a - 160
⇒ 128 = 4a
⇒ a = 32
∴ The larger no is 32.
