The complete question is as follows: A Christmas gift is tied with ribbon the bow requires 47cm of ribbon, what is the total length of the ribbon in cm?
Answer: The total length of the ribbon is 177 cm.
Step-by-step explanation:
As there are 4 sides of the rectangular box and 20 cm of ribbon is on each side. This means that a total of 
= 80 cm is there on the top and bottom.
Hence, length of ribbon attached at the left and right side of the box is as follows.
This means that on both left and right side a total of 50 cm is there.
Therefore, total length of ribbon is as follows.
Total length = 47 cm + 50 cm + 80 cm = 177 cm
Thus, we can conclude that the total length of the ribbon is 177 cm.
<span>A) The data form an almost linear correlation making their most likeable correlation coefficient 0.99. Thus the greater the time elapsed the greater the distance traveled, example of positive correlation.
B) Value of slope for the given time interval is deltaY/deltaX = (12-4)/(30-10) = 8/20 = 0.4. The slope represents the velocity with which the toy car moves, i.e. 0.4miles/min.</span>
Answer:
the probability of the spinner landing on 2 is 25%
Step-by-step explanation:
if there are four different equal parts and there is one spinner
the probability of it landing on any of the parts is 25%
It's 12. I mean think of all the numbers, 6 works for 3 but not 4, 8 works for 4 but not 3 and 10 works for neither.
Answer:
6x² + 12y² + 17xy - 25xz
Step-by-step explanation:
(2x + 3y) (3x + 4y - 5z)
= 6x² + 8xy - 10xz + 9xy + 12y² - 15yz
= 6x² + 12y² + 8xy + 9xy - 10xz- 15yz
= 6x² + 12y² + xy (8 + 9) - xz (10 + 15)
= 6x² + 12y² + 17xy - 25xz
