Answer:
d) 9/4
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given circumference of cylinder A = π r² = 4π units
Given circumference of cylinder B = π r² = 9π units
The dimensions of cylinder A are multiplied by 
circumference of cylinder A = π r² = 4π(
units = 9 π units
circumference cylinder A= 4π( units = 9 π units = circumference of cylinder B
<u><em>Final answer</em></u>:-
<em>The dimensions of cylinder A are multiplied by 9/4 produce the corresponding dimensions of cylinder B</em>
Answer:
7/ (3a-1)
Step-by-step explanation:
3a^2 -13a +4 28+7a
------------------ * --------------------
9a^2 -6a+1 a^2 -16
Factor
(3a-1)(a-4) 7(4+a)

[c] 70°
40+2x=180
2x=140
x=70
i use 2x since the angle measures of D and C are equivalent since it is an isosceles

Answer:
x = 10
y = 11
Step-by-step explanation:
Solve for x:
2x + 3y = 53
3x(3) - y(3) = 19(3)
2x + 3y = 53
9x - 3y = 57
Add:
2x = 53
9x = 57
11x = 110
Solve algebraically:
x = 110 ÷ 11
x = 10
Now solve for y:
2(10) + 3y = 53
20 + 3y = 53
3y = 53 - 20
3y = 33
y = 33 ÷ 3
y = 11
Verify for the second equation:
3x - y = 19
3(10) - (11) = 19
30 - 11 = 19
30 = 19 + 11
30 = 30 (Correct)
Cheers!
