2. A square is divided into smaller squares and
Oduvanchick [21]

Answer:

1.5 ft^2

Step-by-step explanation:

Since the length is divided into 4 parts,

Length of a small square = 2/4

= 0.5 ft

Hence,

Area of 1 small square = (0.5)(0.5)

= 0.25 ft^2

Area of shaded portion = Area of 6 small squares

= 6(0.25)

= <u>1.5 ft^2</u>

Sarah takes 550 mg of an antibiotic. Every hour, her body breaks down 25% of the remaining drug. How much will be left after 12
hammer [34]

The amount of drugs that will be left after 12 hours is 17.42 mg provided Sarah takes 550 mg of an antibiotic every hour.

<h3>What is exponential decay?</h3>

Exponential decay can be described as a reduced amount of an original substance by a definite percentage over a period of time. It can be determined by using the formula:

\mathbf{y = a(1 - r)^t}

where;

  • y = total amount,          
  • a = initial amount = 550 mg
  • r = the growth rate = 0.25
  • t = number of growth periods = 12 hours

\mathbf{y = 550(1 - 0.25)^{12}}

y = 17.42 mg

Therefore, we can conclude that the amount of drugs that will be left after 12 hours is 17.42 mg.

Y=x+2 and x+y=8 in substitution method​
raketka [301]

Answer:

y = x + 2 \\ x + y = 8 \\ x + x + 2 = 8 \\ 2x = 8 - 2 = 6 \\ 2x = 6 \\ x = 6 \div 2 = 3 \\ y = x + 2 = 3+ 2 = 5
