Answer:
a = 3 1/3
Step-by-step explanation:
a+5 2/3 = 9
Subtract 5 2/3 from each side
a+5 2/3 - 5 2/3= 9- 5 2/3
a = 9- 5 2/3
We need to borrow 1 from the 9 in the form of 3/3
a = 8 3/3 - 5 2/3
a = 3 1/3
A child can explain that 3×2 represents 3 sets of 2. Concrete operational, mathematical transformations. A child doesn't sneak a cookie when his mom outside because he thinks that she can see what he sees.
20. you basically do 40/2=20
Answer:
Step-by-step explanation:
So 1cm rep = 24 ÷ 2 = 12
So 3cm rep = 12 x 3 = 36
Answer:
<em>1,172.5cm²</em>
Step-by-step explanation:
Total surface area of a box = 2(LW + WH + LH)
L is the length = 11.5cm
W is the width = 7cm
H is the height = 1.5cm
Substitute
TSA = 2(11.5(7) + 7(1.5) + (11.5)(1.5))
TSA = 2(80.5+10.5+17.25)
TSA = 2(117.25)
TSA = 234.5cm²
<em>Hence the total surface area of a stack of five such compact disc boxes will be 5(234.5) = 1,172.5cm²</em>
