In ΔNOP, p = 72 inches, o = 84 inches and ∠O=19°. Find all possible values of ∠P, to the nearest degree
Answer:
16
Step-by-step explanation:
The value of the angle m∠P is given by the law of sines and m∠P = 16°
What is the law of sines?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°

Lydia invested $5900 in an account paying an interest rate of 2 5/8% compounded monthly. Jace invested $5900 in an account paying an interest rate of 2 1/8% compounded continuously. After 19 years how much more money would lydia have in her account than jace to the nearest dollar.
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: $875

Mohamed wants to buy a television that costs $800, including taxes. To pay for the television, he will use a payment plan that requires him to make a down payment of $200, and then pay $65 each month for 10 months. What is the percent increase from the original cost of the television to the cost of the television using the payment plan?
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:
A large aquarium should contain 10,000 liters of water when it is filled correctly. It will overflow if it gets up to 12,000 liters. The fish will get sick if it gets down to 4,000 liters. The aquarium has an automatic system to help keep the correct water level. If the water level is too low, a faucet fills it. If the water level is too high, a drain opens. One day, the system stops working correctly. The faucet starts to fill the aquarium at a rate of 30 liters per minute, and the drain opens at the same time, draining the water at a rate of 20 liters per minute. How long will it take until the tank starts overflowing or the fish get sick (if it started with 10,000 liters of water)?
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;
The tank will start overflowing after 3 hours and 20 minutes. Method used to obtain the above 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
The time it to overflow is 3 hours 20 minutes.Learn more about rate of change functions here:

The doubling period of a bacterial population is 15 minutes. At time t= 80 minutes, the bacterial population was 90000
Answer:
here i finished!
hope it helps yw!
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

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

Write the linear equation in slope intercept form of a line that is not parallel or perpendicular to y = x - 4
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
