Answer:

m<C = 101°

m<E = 46°

Step-by-step explanation:

*This was the only problem I could figure out so I'm sorry*

C equals 101° b/c 1/2 a circle angle equals 180° which is the line. Angle F and Angle C are corresponding interior angles (same side angles) so if both of them together should equal 180. 180 - 79 (<F) = 101 (<C).

You do the same thing to find Angle E b/c it's corresponding interior angles to Angle D.

I hope you understand this explanation

A shirt and a tie is $64. The shirt costs $30 more than the tie what is the cost of the shirt ?
Bas_tet [7]

Answer:

$47

Step-by-step explanation:

Create a system of equations where s is the cost of a shirt and t is the cost of a tie:

s + t = 64

s = t + 30

Solve by substitution by substituting (t + 30) into the first equation as s:

s + t = 64

(t + 30) + t = 64

Add like terms and solve for t:

2t + 30 = 64

2t = 34

t = 17

Then, plug in 17 as t into one of the equations to find s:

s = t  + 30

s = 17 + 30

s = 47

So, the cost of the shirt is $47

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.
