First, you formulate a ratio of Audrey's work time to work done. In this case, 3/5 hour : 2/5 square yards. Expressing and simplifying that into a fraction would yield:
3/5 ÷ 2/5 = 3/5 * 5/2 = 3/2
We use this ratio to determine the sq yards she could paint in an hour:
1 hour * (1/(3/2) = 2/3 square yards
I hope I was able to help you with this question. Have a good day.
Perform indicated multiplication:
11c+3(-5c)+3(4d)
11c-15c+12d combine like terms
(11c-15c)+12d
-4c+12d factor
4(3d-c)
Given Data:
The sides of the rectangle are 23 m, 23 m ,19 m and 19 m.
The length of the rectangle is 23 m.
Thus, option (B) is the correct option.
A is incorrect - In decimal form, 7/5 is 1.4
B is incorrect - In decimal form, 7/4 is 1.75
D is incorrect - In decimal form, 7/2 is 3.5
The answer is C. 7/4; In decimal form, 7/4 is 2.33333333.... (this represents a terminating decimal)
The slope of this line is

.
Perpendicular lines have opposite reciprocal slopes. To find an opposite reciprocal, multiply by
−
1
and flip the numerator and denominator.
Hence the opposite reciprocal of
