Answer:
30
Step-by-step explanation:
Perimeter of rectangle = 5y - 1 + 4y + 2 + 5y - 1 + 4y + 2
= 18y + 2
18y + 2 = 128
18y = 128 - 2
= 126
y = 126 ÷ 18
y = 7
Length of AD = 4y + 2
= 4(7) + 2
= 28 + 2
= 30
Answer:
3.
Step-by-step explanation:
Since it states it needs to be cut into pieces, it's division, so since it's division we do KCF - keep change flip
We keep the first term, then we change the sign to a multiplication sign and flip the numerator and the denominator for the second term, so your equation would be :
6/8 × 4/1
6 times 4 would be 24, then we put 24 over 8, 24/8, - then you just divide 24 by 8 which would be 3. I hope this helps.
Volume of the wrapper = pi * 0.7^2 * 10 = 4.9pi cm^2
Volume of one tablet = 0.7^2 * 0.5 pi = 0.245pi
Number of tablets in the wrappe = 4.9pi / 0.245pi = 20 (answer)
