Answer:
If you're trynna simplify these are the answers:
4.) -116
5.) -13
Step-by-step explanation:
4.) −4((5)(4)+9)
=(−4)((5)(4)+9)
=(−4)((5)(4))+(−4)(9)
=−80−36
=−116
5.) 9+84−(6)(4)
=9+2−(6)(4)
=11−(6)(4)
=11-24
= -13
Answer:
She subtracted 7x instead of dividing it. Personally, i wouldn't have done that. I would subtract the 14 first, then divide.
Volume of a ball = (4/3)πr³
When r = 18cm, V = (4/3)×3.14×18³ =24416.64 cm³
When r = 12cm, V = (4/3)×3.14×12³ =7234.56 cm³
Difference = 24416.64 - 7234.56 = 17182.08 cm³
the volume of air in the larger ball is <span>17182.08 cm³ greater than smaller ball </span>
Q17:
one week = $560
52 weeks = 560 x 52 = $29120
Q18:
one year = $28500
52 weeks = 28500
1 week = 28500 ÷ 52 = $548
Q19:
5% of $300000 = 0.05 x 300000 = $15000
$15000 + $12000 = $27000
