\left(x^2-8\right)+\left(-2-x^2\right)=-10

\left(x^2-8\right)+\left(-2-x^2\right)

=x^2-8-2-x^2

=x^2-x^2-8-2

=-8-2

=-10

Answer:

d. 21.5

Step-by-step explanation:

To find the missing side length of each triangle, use the pythagorean theorem. The theorem is a^2 + b^2 = c^2 where a, b, and c are all side lengths of the triangle. a is the smallest lef and b is the other leg while c is always the hypotenuse or longest side.

In d, you'll use it twice to find the missing measure. First use it when a = 12 and b = 20. So you'll have:

12^2 + 20^2 = c^2\\144 + 400 = c^2\\544 = c^2\\\sqrt{544} = c\\ 23.32 = c

Repeat the same process using a = 9 and c = 23.32. Then solve for the b value.

9^2 + b^2 = 23.32^2\\81 + b^2 = 544\\b^2 = 544 - 81\\b^2 = 463\\b = \sqrt{463} \\b = 21.5

Answer:

The cost of a chicken shawarma wrap = $10.99

The cost of an order of spiced potatoes=$4.99

Equations needed

3x+2y =42.95

5x + 4y=74.91

Step-by-step explanation:

x = the cost of a chicken shawarma wrap

y = the cost of an order of spiced potatoes

Ms. Ironperson

3x+2y =42.95

Mr. Thoro

5x + 4y=74.91

3x+2y =42.95 (1)

5x + 4y=74.91 (2)

Multiply (1) by 2

6x + 4y=85.9 (3)

5x + 4y=74.91. (2)

Subtract (2) from (3)

6x - 5x= 85.9 - 74.91

x=$10.99

Substitute the value of x into (1)

3x+2y =42.95 (1)

3(10.99) + 2y =42.95

32.97 + 2y = 42.95

2y = 42.95 - 32.97

2y=9.98

Divide both sides by 2

y=9.98/2

=4.99

y=$4.99

Therefore,

The cost of a chicken shawarma wrap = $10.99

The cost of an order of spiced potatoes=$4.99

  • Half life = 10 days
  • Total time = 60 days

<u>Number of half-life periods:</u>

  • r = 60/10 = 6

<u>Equation for remaining sample:</u>

  • s = m*(1/2)^r
  • s = 80*(1/2)^6 = 80/64 = 1.25 g
