Step-by-step explanation:
The ratio's can be expressed as fractions and you may compare those.
In order to compare fractions you need to bring them into equal denominator.
8 and 9 have LCM of 8*9 = 72 since they have no common factors.
<u>The equivalent fractions with common denominator are:</u>
- 5/8 = 9*5/(9*8) = 45/72
- 7/9 = 8*7/(8*9) = 56/72
<u>Now we can compare the fractions:</u>
- 45/72 < 56/72, since 45 < 56
Multiply base times height and your answer should be without decimals it would be 1,056 with decimals it would be 1.56. Hope this helps!
Answer:
B
Step-by-step explanation:
We have 4 being multiplied by itself 8 times. this is written as
4 × 8 → B
Are you sure you want the length to be smaller than the width? It's not exactly the way they're defined. I'll solve it that way, but it's an odd question.
EquationsP = 2L + 2W
Area = L*W
Substitution and Solve2L + 2W = 36
L*W = 56
Divide the first equation by 2
L + W = 36/2
L + W = 18
Solve for L
L = 18 - W
Put this result in the second equation
W(18 - W) = 56 Remove the brackets
18W - W^2 = 56 Transfer the Left Side to the Right.
0 = W^2 - 18W + 56 Factor
0 = (W - 14)(W - 4)
W - 14 = 0
W = 14 <<<<<Answer
W - 4 = 0
W = 4
CommentBoth 14 and 4 are in cm
W = 14 cm <<<< answer
L = 4 <<<<< answer
