Answer:
Sin Z=30/50 or 3/5
Step-by-step explanation:
To figure out Sin Z, you need the formula which is Sin=o/h
O=opposite
H=Hypotenuse
To find opposite, you locate the angle(angle Z) and you draw an arrow that is opposite of the angle. To find hypotenuse, you pinpoint the right angle and you find the degree that it is opposite of.
O=30
H=50
Finally, you simplify 30/50 to get 3/5ths. Hope this helps you out!

What is meant by Percentage?Percentage is defined as the parts of a number per fraction of 100. It is denoted by the symbol '%'.
We can calculate percentage of a number by dividing a number with it's whole and then multiply with 100.
Given,
Cost of the meal before tax or tip = $105.89
Amount of tip = 18% of $105.89
= 18% × 105.89
= 0.18 × 105.89
= $19.0602
Amount of tax = 5% of $105.89
= 5% × 105.89
= 0.05 × 105.89
= $5.2945
Total cost for the meal = $105.89 + $19.0602 + $5.2945
= $130.2447
Total number of friends = 12
Money owed by each friend = $130.2447 / 12
= $10.853725
Hence the money owed by each is $10.853725.

Answers
Answer:
8.5 hours
Step-by-step explanation:
55 x 9.5 (add extra hour) = 552.5 miles
65 x 8.5 (actual time spent) = 552.5 miles
The time taken for Quinn to catch up to Tracy during the journey is 8.5 hours.
Time of motion of Tracy and QuinnThe time of motion of tracy and quinn is determined by using the following equation as shown below;
For tracy, d = 55(t + 1)
For Quinn, d = 65t
where;
55(t + 1) = 65t
55t + 55 = 65t

Find the principal needed now to get the given amount; that is, find the present value.
To get $600 after 4 years at 7% compounded monthly
Answers
The required present value needed now to get $700 after 4 years at 11% compounded monthly is $451.73.
To find the present value of $600 after 4 years at 7% compounded monthly, we can use the formula for compound interest:
Compound Interest =P(1+r/n)^rt
Substituting the given values, we get:
Compound Interest =600 (1+7/n)^4
Simplifying this equation, we get
P = 600 / 1.487
P = 451.73
Therefore, the present value needed now to get $600 after 4 years at 7% compounded monthly is $451.73.

In ΔVWX, x = 6.4 inches, w = 8.8 inches and ∠W=85°. Find all possible values of ∠X, to the nearest 10th of a degree.
Answers
Using the Law of Cosines, we can write the following equation for triangle VWX:
V^2 = W^2 + X^2 - 2WXcos(W)
Plugging in the given values, we have:
V^2 = (8.8)^2 + X^2 - 2(8.8)(X)cos(85°)
V^2 = 77.44 + X^2 - 15.36X
Solving for X, we can use the quadratic formula:
X = (-(-15.36) ± √((-15.36)^2 - 4(77.44)(1)))/2(1)
X = (15.36 ± √(234.84))/2
So the possible values of X are approximately:
X = (15.36 + 15.32)/2 = 15.34 inches
X = (15.36 - 15.32)/2 = 0.02 inches
Converting the length of X to degrees, we can use the inverse cosine function (arccos) to find the angles:
∠X = arccos(X/V)
For the first value of X (15.34 inches), we have:
∠X = arccos(15.34/V)
Since V is not given, we cannot determine a numerical value for ∠X, but it is safe to say that it will be between 0° and 90°.
For the second value of X (0.02 inches), we have:
∠X = arccos(0.02/V)
Since X/V is very close to 0, the cosine value will be close to 1, so the angle will be close to 0°. To the nearest 10th of a degree, ∠X = 0°.

Answers
The rate of decrease of the weather in degrees per hour is 2 degrees.
EquationsThe time elapsed is from 5:00 PM to 9:00 PM, which is 4 hours.
The temperature dropped from 20 degrees to 12 degrees, which is a change of -8 degrees.
Therefore, the rate of decrease of the weather in degrees per hour is:
-8 degrees / 4 hours = -2 degrees per hour
What is rate of change of temperature?A measurement of how quickly the temperature changes over time is the rate of change. Depending on the time frame being considered, it is typically represented in units of degrees per hour, degrees per minute, or degrees per second. Depending on whether the temperature is rising or falling, the rate of temperature change can be either positive or negative. The temperature rises when the rate of change is positive; it falls when the rate of change is negative.
Many variables, including the amount of sunlight, wind speed, humidity, and the time of day, have an impact on the pace of temperature change. Generally speaking, temperature varies more quickly during the day than it does at night, and it varies more quickly in places with less foliage and more exposed ground. Human activity, such as the emission of greenhouse gases into the atmosphere, which can eventually lead to an increase in global temperatures, can also have an impact on the pace of change of temperature.

Simplifying the equation:
2P - 11 = 29

At x = 0 and x = 7, the function g(x) is undefined.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression of the function is,
⇒ g (x) = 6 / x (x - 7)
Now, We know that;
The function f(x) = a(x) /b (x) is not defined at b (x) ≠ 0
Here, The expression of the function is,
⇒ g (x) = 6 / x (x - 7)
So, Function g (x) is not defined when,
x (x - 7) = 0
⇒ x = 0
or, x - 7 = 0
⇒ x = 7
Thus, At x = 0 and x = 7, the function g(x) is undefined.

Do not round any intermediate computations, and round your final answer to the nearest cent. If necessary, refer to the list of financial formalas.
Answers
The total value of the annuity in 26 years is 179163.85 dollars.
Given that, Deandre deposits $97 each month in an annuity that pays 7.7 % interest, compounded quarterly.
The formula used to find the compound interest = \(A=P(1+\frac{r}{100})^{nt}\).
Here, 26 years = 26×4
= 104
Now, A=97(1+7.5/100)¹⁰⁴
A=97(1+0.075)¹⁰⁴
A=97(1.075)¹⁰⁴
A=97×1847.05

The measure of side length x in the right triangle is approximately 6.03 cm.
What is the measure of side length x?The figure in the image is a right triangle having one of its interior angle at 90 degrees.
From the figure:
Angle θ = 37 degrees
Adjacent to angle θ = 8 cm
Opposite to angle θ = x
To solve for the missing side length x, we use the trigonometric ratio.
Note that: tangent = opposite / adjacent
Hence:
tan( θ ) = opposite / adjacent
Plug in the given values and solve for x:
tan( 37 ) = x / 8
x = tan( 37 ) × 8
x = 6.03 cm
Therefore, the value of x is 6.03 cm.
