Answer:

Step-by-step explanation:
This triangle has a small square, which represents a right angle. Therefore, we can use the Pythagorean Theorem.

Where <em>a</em> and <em>b </em> are the legs of the triangle and <em>c</em> is the hypotenuse.
In this triangle, 7 and √15 are the legs, because these sides make up the right angle. The unknown side is the hypotenuse, because it is opposite the right angle. So, we know two values:

Substitute these values into the formula.

Solve the exponents.


Add.

Since we are solving for c, we must isolate the variable. It is being squared and the inverse of a square is the square root. Take the square root of both sides.

The third side length is <u>8.</u>
Gradient of line,m=(17-6)/(20-0)=11/20
finding equation of line using a point (20,17)
y-17=11/20(x-20)
y-17=(11/20x)-11
y=11/20x+(17-11)
y=(11/20)*x+6
Answer: 1/6 is its simplest form :)
Answer:
Five bottles
Step-by-step explanation:
Answer:
1.Convert all volumes to ounces
(a) Chlorpheniramine

(b) Lidocaine
V = 2 oz
(c) Banana flavouring

2.Calculate the total volume
Chlorpheniramine = 3.38 oz
Lidocaine = 2
Banana flavouring = <u>0.08
</u>
TOTAL = 5.46 oz
3. Calculate the number of bottles

The prescription will fill five bottles. The sixth bottle will be less than half-full.
