Answer:
-18 1/5-(-2 3/5)=-15 3/5
-52.89-(-25.63)=27.26
-96 2/9- 24 4/9= -120 2/3
49.40-(-85.63)= 135.03
Answer:
1 space to the right?
Step-by-step explanation:
Answer:
SA = 484 cm²
Step-by-step explanation:
Surface area of the composite figure = surface area of the larger rectangular prism + (surface area of the smaller rectangular prism - base area of the smaller rectangular prism)
✔️Surface are of the larger rectangular prism = 2(LW + LH + WH)
L = 7 cm
W = 7 cm
H = 12 cm
S.A = 2(7*7 + 7*12 + 7*12) = 434 cm²
✔️Surface are of the smaller rectangular prism = 2(LW + LH + WH)
L = 7 cm
W = 2 cm
H = 2 cm
S.A = 2(7*2 + 7*2 + 2*2) = 64 cm²
✔️Base area of the smaller rectangular prism = L*W
L = 7 cm
W = 2 cm
Area = 7*2 = 14 cm²
✅Surface area of the composite figure = 434 + (64 - 14)
= 434 + 50
= 484 cm²
Hopefully you understand this
Scientifc notation is used to make very large decimal number less longer.
so, an example
0.0043, quite a long decimal, right?
You need to create a number through 1-10. so would be to move 3 places
4.3,
Since the spaces we took where 3
we have a 10 with the expoent of negative 3. This is so if you do the problem it will go back to it's orgnally state the decimal was at. ( so you'll know if you did something wrong)
so if should look like this but almost,
=4.3x10(noted there is an -3 exponet on 10)
Hopes this helps!
