Answer:
1: by using this equation x*y=96, or just list out 96's factors
2: 3 by 32
3: no, unless you want to use decimals.
4: finding the surface area
Answer:
17. 11x - 11y or 11x + (-11y)
18. -7.52 - 2.8 or -7.52 + (-2.8)
19. 41x - 21y - 6
20. -3y -8xy
Step-by-step explanation:
17. Use the distributive property.
18. Use the distributive property to multiply each number inside the parentheses by 0.4
19. Multiply each number inside the parenthese by 7.
20.Multiply each term in parenthese by y.
To find the answer we can break the figure into two parts: a rectangle and a semi circle.
The perimeter of the rectangle:
(10+4)×2
=28 ft
The perimeter of the semi circle:
perimeter of a circle: 2×兀×radius
(The radius: 4/2)
We divide the perimeter by two as it is a semi circle,which is half the circumferece perimeter of a circle.
[2(3.14)(4/2)] / 2
=6.28 ft
We can then add up the numbers to find the answer, and remember that 4 cm is overlapped:
28+6.28-4
=30.28ft
Therefore the answer is 30.28ft.
Hope it helps!
Answer: a and d
Step-by-step explanation:
First of all, we need to make a analysis of each letters:
a. factoring 32 = 2.2.2.2.2 = 
then,
16 = 
but 
in conclusion that, this inequality is correct
b. 27 = 
this first situation is equal to 
the second situation is:
81 = 
and 
it's a mistake.
c. factoring 9: 
< 
it's wrong.
d. factoring 8 = 
factoring 32 =
> 
This is true.
Finally.. our correct answers is a and d.
0.6 miles.
Since there is 0.8 miles to hike in total, she hiked 0.2 miles.
To solve, we just easily subtract the amount that Liz hiked from the amount that needs to be hiked.
She hiked 0.2 miles, which means we need to subtract 0.2 from 0.8.
8 - 2 = 6
The answer is 0.6 miles.
