Answer:
7 minutes
Step-by-step explanation:
When Rob climbed the Eiffel Tower today, he climbed 1,000 steps in 25 minutes.
Today
Steps : minutes = 1000 : 25
If he climbs at the same rate, how many minutes will it take Rob to climb the stairs tomorrow
Let x = number of minutes it will it take Rob to climb the stairs tomorrow
Tomorrow
Steps : minutes = 280 : x
Equate both ratios
1000 : 25 = 280 : x
1000 / 25 = 280 / x
Cross product
1000*x = 25 * 280
1000x = 7000
Divide both sides by 1000
x = 7,000 / 1,000
= 7
x = 7 minutes
B) No, because opposite sides are not parallel
Step-by-step explanation:
Given this information, assume that quadrilateral WXYZ is a parallelogram then we expect;
Parallel sides to be : WX // YZ and XY // WZ
Additionally, we know parallel sides have equal gradient thus;
The slope of side WX= slope of side YZ and the slope of side XY= that of side WZ
However, from the information given, m of WX= 1/3 and that of YZ is -3, thus the two sides are not parallel to each other but perpendicular to each other because the product of their slope equals -1.
