Answer:
Ok, so we have the fact that plus +minus=minus
Thats the fact. It always works that way that same signs means positive and different means negative, as explained with logic.
4+(-5)
So we know that 4 is positive and -5 is negative
if you look at it through a number line, substracting 5 from 4 you have
3--->2---->1---->0---->-1
Under zero, the negatives start, so its proved by maths and logic as well.
Step-by-step explanation:
Answer:
The correct option is C.
Step-by-step explanation:
From the given figure it is noticed that the coordinates of B are (-5,-7).
If ABC is reflected across x = 1, then
If ABC is reflected across y =-3.
Therefore option C is correct.
1. Perimeter is 3 + 3 +3 +4 +5 = 18 feet
Area = 3*3 = 9, 1/2*3*4 = 6, 9 + 6 =15 square feet
2. perimeter = 2.5 +2.5+ 2.5+2.5+0.5+0.5 = 11 meters
Area = 3*.5 = 1.5, 3*2=6, 6+1.5 = 7.5 square meters
3. perimeter = 3.14*2*3 = 18.84 +8 = 26.8 inches
Area = 6*4 = 24 + 3.14*3^2 = 28.26 = 28.26 +24 = 52.3 inches
4. surface area = 2*π*6*20+2*π*6^2= 980.2 yards
Volume = π*6^2*20 = 2261.9 cubic yards
5.surface area
= 2*(9*7+2*2+2*9) = 190 cm
Volume = 2*7*9 = 126 cubic cm
6. surface area = <span>2*(11*11+11*11+11*11) = 726 mm</span>
<span> Volume = 11 *11*11 = 1331 cubic cm</span>
The maximum height is 64ft and the ballon is only in the air for 2 seconds
