Answer:

m ∠JPN = 131°

Step-by-step explanation:

m ∠JPL = m ∠MPK Vertical angles are =

7x + 19 = 11x -17 Substitution

- 4x = -36 Algebra: Solving for x

x = 9 Algebra: Solving for x

m ∠JPL = 82° Substitution x = 9 into m ∠JPL = 7x +19

m ∠JPL + m ∠LPK = 180° Definition of linear pair/supplement

angles = 180°

82° + m ∠LPK = 180° Substitution

m ∠LPK = 98° Algebra

m ∠LPK = m ∠LPN + m ∠NPK Angle addition Theorem

PN bisects ∠LPK Given

m ∠LPN = m ∠NPK Definition of angle bisector

98 ° = 2 ( m ∠LPN) Substitution

m ∠LPN = 49° Algebra

m ∠JPN = m ∠JPL + m ∠LPN Angle Addition

m ∠JPN = 82° + 49° Substitution

m ∠JPN = 131° Addition

How many gallons of pure water should be evaporated from 160 gallons of a solution containing 12% salt

AfilCa [17]

Answer:

66 gallons

Step-by-step explanation:

Given that initially 160 gallons of a solution containing 12% salt.

So, the initial amount of salt = 12% of 160 = 12/100 x 160 = 19.2 gallons.

Let x gallons of water get evaporated so that the remaining solution contains 20% salt.

The remaining amount of solution = 160-x gallons.

As the initial amount of salt is still in the solution which is equal to 20% of the remaining solution, so

19.2 = 20% of (160-x)

$\Rightarrow 19.2 = \frac {20}{100}\times (160-x) \\\\\Rightarrow 19.2 = \frac {1}{5}\times (160-x) \\\\\Rightarrow 19.2 \times 5= 160-x \\\\\Rightarrow 96= 160-x \\\\\Rightarrow x= 160-96 \\\\$

$\Rightarrow x= 66$ gallons

Hence, 66 gallons of water must be evaporated to get a 20% salt solution.

An object that weighs 24 pounds on Mercury weighs approximately 80 pounds on Earth. A rock weighs 240 pounds on Mercury. What is

AnnyKZ [126]

Answer:

800 pounds.

Step-by-step explanation:

We have been given that an object that weighs 24 pounds on Mercury weighs approximately 80 pounds on Earth. A rock weighs 240 pounds on Mercury. We are asked to find the weight of rock on Earth.

We will use proportions to solve our given problem as proportions state that the ratio between two proportional quantities is equal.

$\frac{\text{Weight on Earth}}{\text{Weight on Mercury}}=\frac{80}{24}$
