Answer:
-3b^4 (6b^3 -b-5)
Step-by-step explanation:
Each term is divisible by 3b^4 so we can factor this out
3b^5 + 15b^4-18b^7
3b^4( b+5 -6b^3)
Rewriting the inside term
3b^4 (-6b^3 +b+5)
We can factor out a negative
-3b^4 (6b^3 -b-5)
Answer:
11 pieces
Step-by-step explanation:
19 1/4 ÷ 1 3/4
19 x 4 = 76 + 1 = 77
1 x 4 = 4 + 3 = 7
77/4 ÷ 7/4
77/4 ÷ 7/4 = 11/1
11 pieces
(Just copy my work above for Part B)
Answer:
142.85 (rounded off to two decimal places)
Step-by-step explanation:
given
(49/100)x = 56
x = (56/49)100

we get
x= 142.85....
Answer:
CB = 20 or D
Step-by-step explanation:
Remark
You have a proportion. A proportion consists of 2 equal ratios. Three parts of the Proportion of 4 much be known. Then you can solve for the 4th.
Formula
Large vertical / Small Vertical = large horizontal / Small horizonal. Notice how Large goes on top of the ratios and small on the bottom.
Givens
Large Vertical: 8 feet
Small Vertical: 5 feet
Large horizontal: CA + 12.5 feet
Small Horizontal: 12.5
Solution
8/5 = (CA + 12.5) / 12.5 Cross Multiply
5(CA + 12,5) = 8 * 12.5 Remove the Brackets
5CA + 62.6 = 100 Subtract 62.5 from both sides.
5CA = 37.5 Divide by 5
CA = 7.5
CB = CA + 12.5
CB = 7.5 + 12.5
CB = 20
Answer
D
