Answer:
1) 4 wild cards
2) 51.5 bones, rounded up to 52 bones
3) 72 blue balls.
Step-by-step explanation:
1) For every 18 cards in the game, there is 1 wild card.
For 72 cards in the game, there are 72/18 * 1 = 4 wild cards.
2) For every 4 bones, 1 is in the feet.
For 206 bones, 206/4 * 1 = 51.5 are in the feet. Though, you can't have half a bone, so I'd round it up to 52 bones in the feet.
3) For every 6 + 5 = 11 balls, there are 6 blue and 5 red.
For every 132 balls, there are 132/11 * 6 = 72 blue and 132/11 * 5 = 60 red.
There are 72 blue balls.
Answer:
45
Step-by-step explanation:
The n th term of a GP is
= a
where a is the first term and r the common ratio
Given a₂ = 6 and a₅ = 48, then
ar = 6 → (1)
a
= 48 → (2)
Divide (2) by (1)
= 
, that is
r³ = 8 ( take the cube root of both sides )
r = ![\sqrt[3]{8}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D)
= 2
Substitute r = 2 into (1)
2a = 6 ( divide both sides by 2 )
a = 3
Thus
3, 6, 12, 24 ← are the first 4 terms
3 + 6 + 12 + 24 = 45 ← sum of first 4 terms
I was a little confused myself but if it is asking for the cost of the sneakers after the 20% off from the amount of money the store had to pay, it would be D, $21.84. The way to do this would be to find the cost of the sneakers when the store bought them. You multiply the percentage in decimal form with the cost of the sneakers at the price the store was selling it: 0.3*39 = 11.7. Then, to get the price the store bought them at, you would subtract that price from $39 to get $27.30. Finally, you apply the 20% discount to 27.30 by multiplying 0.2 to it and subtracting that price from 27.30. Then your answer will be $21.84. However, if the problem was asking for the cost of sneakers after the 20% off from the price the store was selling it, it would be A, $31.20. You would have to multiply the 20% discount straight to the price the store is selling the sneakers, $39. Then subtract that price from $39 to get $31.20.
Answer:
y=4-0.5x
Step-by-step explanation:
Step one:
given data
Alina bought an ice cream cone for $3
the weight of the ice cream is 4 ounce
the rate of melting is 0.5 ounce per minute
let the number of minutes taken for the ice cream to melt be x
and the weight after x minutes be y
Step two:
Hence the expression for the situation after x minutes is
y=4-0.5x
Answer:
The answer is 27
Step-by-step explanation:
This is because each person can have up to three roles, and there are 9 students. So you can form an array, or a table to show your values. so if you have 9 rows and 3 coulombs and you can have 27 crosses in the array.
