Answer:
for a it would be 11/18 and for b it would be 4/9
Step-by-step explanation:
This is because I did the same butterfly method. 5 times 5 times 18 which is 90 for 5/9 and 9 times 18 is 99 for 11/18, you can also write it as 5/9 and 11/18 but cross multiply. This is also what I did with the second one.
The answer is:
7 divided by x
and x being the length of all of them together since there are 7 identically sized pieces
B. To be careful, use brackets: 10(1*2) + 4x which will be 20 + 40x or as you have it, 10*2 + 40x.
Answer:
2,712.96 yd³
Step-by-step explanation:
The formula for finding the volume of a cylinder:
πr²h
π (in this case) = 3.14
r = radius
h = height
In this picture, we are given all of the values we need to set up and solve this equation.
r = 12 yd
h = 6 yd
3.14(12)^2 · 6
3.14(144) · 6
452.16 · 6
2,712.96
Answer:
D: 10a+10 ; 5(2a+2)
Step-by-step explanation:
25+3(a-5)+7a
= 25+3a-15+7a
=10+10a
