Answer:
c. 30.0 minutes
Step-by-step explanation:
Max mows 1/45 lawns per minute.
Jan takes twice as long (90 minutes per lawn), so mows 1/90 lawns per minute.
Working together, they mow ...
(1/45 + 1/90) lawns per minute = (2/90 +1/90) lawn/min = 3/90 lawn/min
= 1/30 lawn/min
Then for one lawn, it takes ...
(1 lawn)/(1/30 lawn/min) = 30 min
Answer:
Length of each piece = 16cm.
Step-by-step explanation:
Since the chart paper is 48cm x 32cm in size, finding the total area of the paper would be A = l x w, where l=length of the paper and w=width.
A = 48 x 32 = 1536cm²
Since Stitu was able to get 6 equal pieces, then we can take the total area and divede by 6:

Since 256cm² represents the area of each square, we can take the square root of this number to find the length of just one square since the formula for the area of a square is A=s², where s=the length of one side:
s² = 256 so √s² = √256 or s = 16cm
The answer is D. This is because they both contain W
Around 14 weeks
45*14=630
675-630=45
So around 14 weeks
Answer:
Step-by-step explanation:
A parallelogram is a 4-sided polygon whose opposite sides are equal. By definition, opposite angles are also equal. A square, rectangle, or rhombus are considered as a parallelogram. Among the choices, the correct answer is D. "Opposite angles are congruent"
