Answer: Lenayah's presentation was 12 minutes long.
Step-by-step explanation:
- Set up a proportion. 2/3 = 8/x.
- Cross multiply. 2x = 24
- Divide both sides by 2. x =12
Answer:
yes
Step-by-step explanation:
because area of sphere equals =
so if we doubled the radius the surface area will be doubled
Lana = x
Pam = 0.5x - 0.05
Cheryl = 0.5x - 0.05 + 3.10
Total 89$ = Lana + Pam + Cheryl
89 = x + 0.5x - 0.05 + 0.5x - 0.05 + 3.10
89 = 2x + 3
89 - 3 = 2x
86 = 2x
86/2 = x
43 = x
then Pam = 0.5(43) - 0.05
= 21.50 - 0.05
= 21.45
Cheryl = 21.45 + 3.10
= 24.55
of the attendees were females wearing earrings.
Step-by-step explanation:
As per the given information, there were 
females in the party.

Answer:
T = 5c +5d, where unit of the equation is $.
Step-by-step explanation:
Cost of 1 large cheese pizza = $5
No. of large cheese pizza = c
therefore
cost of c large cheese pizza = c*Cost of 1 large cheese pizza = $5c
Cost of 1 large one topping pizza = $6
No. of large one topping pizza = d
therefore
cost of d large one topping pizza = d*Cost of 1 large one topping pizza = cost of d large one topping pizza = $6d
Total cost of c large cheese pizza and cost of d large one topping pizza
= $5c +$6d
total cost is represented by T
thus, T = $5c +$5d Answer
