Answer:

  • let a, c represent costs for adults and children, respectively
  • 12c+3a=162; 8c+3a=122

Step-by-step explanation:

You are asked only for the setup, not the solution.

I find it convenient to use variable names that remind me of what they stand for. Here, we're asked for the admission prices for adults and children, so 'a' and 'c' are convenient variables to represent those values.

  Let a represent the admission price for an adult.

  Let c represent the admission price for a child.

__

The first sentence gives a relation between the numbers and the total cost:

  162 = 12c +3a

The second sentence gives a different relation:

  122 = 8c +3a

These are the "system of equations."

_____

You aren't asked for the solution, but it is (a, c) = (14, 10). It can be found easily by subtracting the second equation from the first.

What is the probability of rolling an even number or a perfect square using a 20-sided die?
Gemiola [76]

Answer:

C) 12/20

Step-by-step explanation:

Between 1 and 20, 10 numbers are even, 4 numbers are perfect squares (1, 4, 9, and 16), and 2 numbers are both even and perfect squares (4 and 16).

So the probability is:

(10 + 4 − 2) / 20 = 12/20.

Archy [21]

Answer:

The population will be 896 turtles 6 years later ⇒ B

Step-by-step explanation:

The exponential increasing formula is y = a(1+r)^{x}, where

  • y is the new value
  • a is the initial value
  • r is the rate of increase in decimal
  • x is the time in years

∵ There are 300 turtles

∴ a = 300

∵ The population of the turtles exponentially increases 20% each year

∴ r = 20%

→ Divide it by 100 to change it to decimal

∵ 20% = 20 ÷ 100 = 0.2

∴ r = 0.2

∵ The time is 6 years

∴ x = 6

→ Substitute these values in the exponential formula above

∵ y = 300(1+0.2)^{6}

∴ y = 300(1.2)^{6}

∴ y = 895.7952

→ Round it to the nearest whole number

∴ y = 896

∴ The population will be 896 turtles 6 years later

Rewrite i^2 as -1

((-1) ^2) 6

Raise -1 to the power of 2

1^6

One to any power is 1.
