Answer:
110
Step-by-step explanation:
Substitute x = 4 and y = 7
20 + 2 (3y - 4x)
= 20 + 2 [(3 x 7) - (4 x 4)]
= 20 + 2 (21 - 16)
= 20 + 2 (5)
= 22 (5)
= 110
Answer:
<em>8 units</em>
Step-by-step explanation:
Given the relationship between the radius, r, of a sphere and its surface area, A expressed as;
r = 1/2( A /4 π )
We are to find the radius r when Area A is 64π
Substitute A = 64π into the expression and get r as shown;
Recall that: r = 1/2( A /4 π )
r = 1/2( 64 π/4 π )
r = 1/2(16)
r = 16/2
r = 8units
<em>Hence the radius of the sphere will be 8 units</em>
Put the numbers in order
1,2,3,5,6,9,9
Q1 = 2
Q2 (median -- middle number) = 5
Q3 = 9
IQR = Q3 - Q1 = 9 - 2 = 7
Answer:
b
Step-by-step explanation:
The sum of 2 and y is 2 + y, then 4 times this sum is
4(2 + y) → b
