Answer:
B
Step-by-step explanation:
4.5 x 6 = 27
4.5 x 8 = 36
27 x 2 = 54
36 x 2 = 72
54 + 72 = 126cm Perimeter/
27 x 36 = 972 cm2 Area/
Answer:
C) The total number of about uniforms needed is 60 x 80 uniforms.
Step-by-step explanation:
The Number of total stores the owner has = 64 stores
The number of employees uniform needed in 1 store = 79 uniforms
Now, 64 is Rounded off to about 60.
and 79 is Rounded off to about 80.
⇒ The total number of uniforms in 60 stores = 60 x ( uniform in 1 store)
= 60 x (80 uniforms)
or, the expression of total uniforms needed = 60 x (80 uniforms)
Hence, the total number of about uniforms needed is 60 x 80 uniforms.

Answer:
-24degC
Step-by-step explanation:
-6degC dropping by 2degC leads to -8degC (2degC colder, higher value negative numbers are colder as negative numbers increase in the opposite direction of positives)
so next -8degC rising by 3degC which is 3degC hotter(less negative) will give -5degC
the finap drop by 9degC makes the final temperature -5 -19 = -24degC(similar reasoning)
if you want a more straightforward method to doing these sorts of questions, just take temperature rise : add the value it rose by and temperature fall/drop: subtract the value it dropped/falled by.
