answer is d 60 feet squared
Step-by-step explanation:
6×10=60
The answer is $0.8
200/160=1.25
200+160=360/1.25/160=200.8
so the answer is $0.8
Answer:
27.91 pretzels.
Step-by-step explanation:
Knowing that 1/3 of 33 bakers can make 89 pretzels in 2 1/2 hours, to determine how many pretzels can 5 3/4 bakers make in 1 1/2 hours the following calculation must be performed:
33 x 1/3 = 11
89 / 2.5 / 11 = X
35.6 / 11 = X
3.236 = X
3/4 = 0.75
3.236 x 1.5 x 5.75 = X
4.854 x 5.75 = X
27.91 = X
Therefore, 5 3/4 bakers can make 27.91 pretzels in 1 1/2 hours.
Answer:
3 and 4
Step-by-step explanation:
3) 1=-(-1)
1=1
0=0
4) 0=0
when both sides are equal means it is true.
Answer:
x = -3,0,3
Step-by-step explanation:
5x^3 – 45x = 0
Factor out 5x
5x( x^2 - 9) =0
Factor inside the parentheses which is the difference of squares
a^2 - b^2 = (a-b)(a+b)
5x( x-3)(x+3) =0
Using the zero product property
5x =0 x-3=0 x+3 =0
x=0 x=3 x=-3
x = -3,0,3
