Answer:
(X, Y, Z) = (8, 28, 32)
Step-by-step explanation:
The ratio units will form a geometric sequence if the middle one is the square root of the first and last:
Y' = √(2·8) = 4
To get this value from 7, we must subtract 3. In the real sequence we must subtract 12, so each "ratio unit" must stand for 12/3 = 4 real units, and the real numbers X, Y, Z are 2·4 = 8, 7·4 = 28, 8·4 = 32.
(X, Y, Z) = (8, 28, 32)
(X, Y-12, Z) = (8, 16, 32) . . . . a geometric sequence with a ratio of 2
<u><em>Each answer is under each Part</em></u>
1. What is the price of you pizza with all the toppings?
<em><u>$16</u></em>
The pizza costs 12 dollars, and each topping costs 1.75 dollars, there are 4 toppings, so it's 12 + 1.75*4 = 12 + 4 = 16 dollars.
2. How much will you pay in tax?
<em><u>$0.80</u></em>
It costs 16 dollars and tax is 5%, so 5% of 16. 16*5% = 16*0.05 = 0.8, so 0.8 dollars, or $0.80
3. What is the total cost including tax?
<u><em>$16.80</em></u>
Add the cost of the pizza with the tax, 16 + 0.8 = 16.8, $16.80
4. How much will each of you need to pay to cover the total price?
<u><em>$4.20</em></u>
There are 4 people total, You and 3 friends, so divide the total cost by 4, 16.80/4 = 4.2, so $4.20

Step-by-step explanation:
Answer:
the maximum number of snow balls can bought back = 1.6
Step-by-step explanation:
Let
Mrs. Hector brings total number of giant snow globes = x
As given,
weight of 1 snow globe = 1.5 kg
So,
Weight of x snow globe = 1.5x
As given,
She have to take them in a suitcase of weight 2.4 kg
∴
For number of snow globes we have the equation,
1.5x = 2.4
⇒x = 
= 1.6
So, the maximum number of snow balls can bought back = 1.6
