Answer:
The time taken by Nolan to complete multiplication test is 100 seconds .
Step-by-step explanation:
Given as :
The time by Kong to complete multiplication test = x = 85 seconds
The time by Kong to complete multiplication test = 15 % less than that of Nolan
Let The time taken by Nolan to complete multiplication test = y seconds
<u>Now, According to question</u>
∵The time by Kong to complete multiplication test = 15 % less than that of Nolan
So, The time by Kong to complete multiplication test = time taken by Nolan - 15% of time taken by Nolan
i.e x = y - 15 % of y
Or, x = y × (1 - )
Or, x = y ×
Or, x = y ×
Now, Since x = 85 seconds
So, 85 = y ×
Or, y =
i.e y = 100
So,The time taken by Nolan to complete multiplication test = y = 100 seconds
Hence,The time taken by Nolan to complete multiplication test is 100 seconds . Answer
Answer:
I say number 2
Step-by-step explanation:
0.02 is 2 cents while 0.20 is twenty sense. That would make more sense
Answer:
I would say 3/7 x 2/14 or something like that.
1 kilometer is equal to about 0.62 miles.
Multiply each side by 19.08 and you get:
19.08 km = 11.86 miles
Answer:
Parallel: y = (2/5)x - 7/5
Perpendicular: y = (-5/2)x + 3/2
Step-by-step explanation:
Parallels lines have the same slope,
And it also needs to pass through (1, -1)
for an equation as y = mx + b, the only information missing is the y-intercept, it can be found replacing everything else.
-1 = (2/5)(1) + b
-1 - 2/5 = b
-7/5 = b
The equation for the line parallel is y = (2/5)x - 7/5
Perpendiculars when you multiply its slopes the result is -1 , assuming m = the slope of the perpendicular line
(2/5) * m = -1
m = -5/2
Now you have to replace the point and the slope to get the y-intercept as the previous line:
y = mx + b
-1 = (-5/2)(1) + b
-1 + 5/2 = b
3/2 = b
y = (-5/2)x + 3/2
