Answer 1
Answer:

The given condition is- A bottle contains 20% milk and the rest water. The bottle has 1 liter of water.

Part A:

Let the amount of mixture in the bottle be = x ; mixture will be amount of water plus milk

Given is- the bottle has 1 liter of water and 20% is milk. 20% is 0.2

Hence equation will be:

0.2x+1 =x

Part B:

Solving the equation

x-0.2x=1

0.8x=1

x=(1)/(0.8) = 1.25

Hence, total mixture is 1.25 liters.

Water is 1 liter so milk will be = 1.25-1=0.25

Or it can also be solved using milk percentage of 0.2%

0.2*1.25=0.25

Hence, milk is 0.25 liter

Find the measure of Angle 5. measure of angle 7 = 2x+15 measure of angle 8 = 3x

Answers

* 7 = 2x+15 
-2X = 15 - 7
X = 8/-2
x = -8/2     

*8 = 3x
3x = 8
x = 8/3      

Solve
7 + x - 15 = 2 2/3

Answers

Get x on its own side

7+x-15=2 2/3
       +15 +15
  7+x=17 2/3
  -7      -7
     x= 10 2/3
Hope I helped
Let's solve your equation step-by-step.7+x−15=223
Step 1: Simplify both sides of the equation.
x−8=8/3
Step 2: Add 8 to both sides
.x−8+8=8/3+8x=32/3

What is the distance between a given point on a parabola and the parabola’s focus if the distance between the same given point and the parabola’s directrix is 5 units?

Answers

• 5 units

parabolas are geometrically defined as a set of points that're equidistant from a focus point and a directrix line.

equidistant means equally distant.

distance between the given point on parabola and the directrix is 5 units.
therefore, by definition, dist. between given point and the focus is also 5 units.
