Answer:

16

Step-by-step explanation:

The value of the angle m∠P is given by the law of sines and m∠P = 16°

The relationship between a triangle's sides and angles is provided by the Law of Sines. Trigonometry's law of sines can be expressed as a/sinA = b/sinB = c/sinC, where a, b, and c are the lengths of the triangle's sides, and A, B, and C are the triangle's respective opposite angles.

Law of Sines :

a / sin A = b / sin B = c / sin C

Given data ,

Let the triangle be represented as ΔNOP

Now , the measure of side p = 72 inches

The measure of side o = 84 inches

And , the measure of angle ∠O = 19°

From the law of sines , we get

a / sin A = b / sin B

On simplifying , we get

sin p / 72 = sin o / 84

Multiply by 72 on both sides , we get

sin p = ( 72 / 84 ) sin ( 19 )°

On further simplification , we get

sin p = ( 0.857 ) x 0.325568

sin p = 0.279058

Taking inverse on both sides , we get

p = sin ⁻¹ ( 0.279058 )

p = 16.204°

Therefore , the value of p is 16°

Hence , the measure of angle ∠P = 16°

The inequality that describes the possible value of x is 2< x < 22.

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.

Given that ∠A = 50°

AB ≈ DE ≈ EF

BC = 12

CD = 10

And the ∠E = (5x - 10)°

From the Graph, we can see that Angle A is the alternate angle to angle G

Alternate angles are the angles that occur on opposite sides of the transversal line. We can easily spot two interior alternate angles by drawing Z. The value of alternate angles is equal.

thus, ∠A = ∠E

50° = 5x -10

5x = 60

x = 12

Therefore, from the given options the value of x lies in the inequality 2 < x < 22.

Answer:

The water level is rising because it is filling 10 more liters than it is draining

16.7 hours

Step-by-step explanation:

The rate at which the tank is filled and the rate at which the tank is draining

are constant.

Correct response;

Given:

Volume of water in the aquarium = 10,000 liters

Volume level at which the tank overflows = 12,000 liters

Level of the volume at which the fish get sick = 4,000 liters

Rate at which water enters the tank = 30 liter per minute

Rate at which the tank is draining the water = 20 liters per minute

Required;

The time it will take until the tank starts overflowing.

Solution:

Water that needs to be added to the tank before it begins to overflow = 12,000 liters - 10,000 liters = 2,000 liters

Let x represent the time after which the tank starts overflowing, the

(constant) rate of change function that gives the time it takes for the water

to overflow is therefore;

30·x - 20·x = 2,000

10·x = 2,000

x = 200 minutes = 3 hours and 20 minutes

Answer:

6.25%

Step-by-step explanation:

I'm simply returning the favor.

If the down payment is $200, then we can subtract:

$800 - $200 = $600

Then we can find the "rent" times ten, then subtract it from the $600 left to pay.

$65*10 = $650

Now here is the hard part. We know that 600 < 650. So we need to subtract 650 from 600.

$650 - $600 = $50

Now we need to find how much more Mohamed paid than the original price.

$850 is _____% more than $800.

$850 is 106.25% more than $800.

Subtract 100% to get the difference.

6.25% is your answer.

Step-by-step explanation:

Janice's age is 35 years.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Ross age = x

Now,

Janice age = 5x ____(1)

Janice age = x + 28 _____(2)

From (1) and (2),

5x = x + 28

5x - x = 28

4x = 28

x = 7

Now,

Janice age.

= 5 x 7

= 35

Thus,

Janice's age is 35 years.

Step-by-step explanation:

The doubling period of a bacterial population is 15 minutes.

At time t = 90 minutes, the bacterial population was 50000.

Round your answers to at least 1 decimal place.

:

We can use the formula:

A = Ao*2^(t/d); where:

A = amt after t time

Ao = initial amt (t=0)

t = time period in question

d = doubling time of substance

In our problem

d = 15 min

t = 90 min

A = 50000

What was the initial population at time t = 0

Ao * 2^(90/15) = 50000

Ao * 2^6 = 50000

We know 2^6 = 64

64(Ao) = 50000

Ao = 50000/64

Ao = 781.25 is the initial population

:

Find the size of the bacterial population after 4 hours

Change 4 hr to 240 min

A = 781.25 * 2^(240/15

A = 781.25 * 2^16

A= 781.25 * 65536

A = 51,199,218.75 after 4 hrs

Answer:

$875.18

Step-by-step explanation:

Given data

Lydia

P=$5900

Interest rate=2 5/8% >>21/8= 2.625%

compounded monthly.

First, convert R percent to r a decimal

r = R/100

r = 2.625%/100

r = 0.02625 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 5,900.00(1 + 0.0021875/12)^(12)(19)

A = $ 9,710.01

Jace

P=$5900

Interest rate= 2 1/8% >>> 17/8>> 2.125%

Time= 19 years

First, convert R percent to r a decimal

r = R/100

r = 2.125%/100

r = 0.02125 per year,

Then, solve our equation for A

A = Pert

A = 5,900.00(2.71828)^(0.02125)(19)

A = $ 8,834.83

Hence the difference in their account balance is

= 9,710.01- 8,834.83

=$875.18

Therefore Lydia has $875.18 more money than Jace

Answer:

y = xa - (4 + b)

where a or b do NOT = 1

Step-by-step explanation:

changing a changes the angle of the line, where as changing b changes how high up or down the y-axis the line crosses at

the current problem draws a line that is 45 degrees and crosses the y-axis at -4, we can change that in any way, if we make a = 3, then the slope will be 3 times greater then if it was 1, if it was 1/3 then it would be 1/3 of the slope, making it seem flatter and less steep

i hope this helps you create your own formulas now and in the future, this is a reference sheet i made for my own schooling, though i used a different example problem

as always. y = mx + b and have a great day :D
