Answer: angle ITU = 145 degrees
===============================================
Explanation:
Angle STU is the largest angle composed of the smaller angles STI and ITU.
In other words, the two smaller angles add up to the larger one.
(angle STI) + (angle ITU) = angle STU
( 20 ) + ( 12x+1 ) = 13x + 9
20+12x+1 = 13x+9
12x+21 = 13x+9
21-9 = 13x-12x
12 = x
x = 12
Using this x value, we find that,
angle ITU = 12x+1 = 12(12)+1 = 145 degrees
----------
As a side note,
angle STU = 13x+9 = 13(12)+9 = 165 degrees
This is confirmed with
(angle STI) + (angle ITU) = (20) + (145) = 165 = angle STU

The credit remaining on a phone card (in dollars) is a linear function of the total calling time made with the card (in minutes). The remaining credit after 32 minutes of calls is $21.16, and the remaining credit after 56 minutes of calls is $18.28. What is the remaining credit after 72 minutes of calls?
Answers
Answer:
The credit remaining on a phone card is 16.36 dollars
Step-by-step explanation:
A linear function is a polynomial function of the first degree of the form:
f (x) = m * x + b or y = m * x + b
where m is the slope of the linear function and b is the ordinate to the origin and it is the coefficient of the independent variable.
Given the coordinates of two points (x1, y1) and (x2, y2), you can determine the slope of the linear function using the following formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
The coefficient b is calculated simply by replacing any of the points in the linear function, knowing m, and isolating the value.
In this case you want the linear function first:
credit remaining on a phone card= m* the calling time in minutes + b
Being the points (32; 21.16) and (56;18.28), then the slope m will be:
[tex]m=\frac{18.28-21.16}{56-32}[/tex]
m= -0.12
Then, replacing the point (32; 21.16) in
credit remaining on a phone card= -0.12* the calling time in minutes + b
you get:
21.16= -0.12*32 + b → 21.16= -3.84 + b → 21.16 + 3.84= b → 25=b
Then, replacing the point (56;18.28) in
credit remaining on a phone card= -0.12* the calling time in minutes + b
you get:
18.28= -0.12*56 + b → 18.28= -6.72 + b → 18.28 + 6.72= b → 25=b
You can see that the value of b is the same.
So the linear function is:
credit remaining on a phone card= -0.12* the calling time in minutes + 25
Being the call time in minutes equal to 72, you replace this value in the linear function:
credit remaining on a phone card= -0.12* 72+ 25
and you get:
credit remaining on a phone card= -8.64+ 25
credit remaining on a phone card= 16.36
The credit remaining on a phone card is 16.36 dollars

Part E: What is an appropriate domain for the

B. 0
C. Sy s 44.7
DO Sy 5 760
Answers
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, the complete question is:
A skydiver is 760 meters above the ground when he opens his parachute. After opening the parachute, he descends at a constant speed of 17 meters per second.
a) A function gives a relationship between two variables (an independent and dependent variable). The dependent variable is dependent on other variables (output) while the independent variable is not dependent on other variables (input).
Let x be the number of seconds after the parachute is opened and y be the height of the parachute above the ground. Hence the equation that models the situation is:
y = 760 - 17x
At a height of 400 m, the number of seconds is:
y = 760 - 17x
400 = 760 - 17x
17x = 760 - 400
17x = 360
x = 21.2
x ≅ 21 seconds
It takes 21 seconds to reach a height of 400 m
b) Domain is the set of all independent variables. In this case the independent variable is the time (x)
The minimum time is at y = 760
y= 760 - 17x
760 = 760 - 17x
17x = 0
x = 0
The maximum time is at y = 0
y= 760 - 17x
0 = 760 - 17x
17x = 760
x = 44.7
Hence the domain = 0 ≤ x ≤ 44.7

[tex]x = \frac{-3d-9}{k-d}[/tex]
Step-by-step explanation:
Step 1: Write out equation
d(-3 + x) = kx + 9
Step 2: Distribute d
-3d + dx = kx + 9
Step 3: Subtract 9 on both sides
-3d + dx - 9 = kx
Step 4: Subtract dx on both sides
-3d - 9 = kx - dx
Step 5: Factor out x
-3d - 9 = x(k - d)
Step 6: Divide both sides by k - d
[tex]x = \frac{-3d-9}{k-d}[/tex]

Alden has a gift card for a local garden store. She uses the gift card to rent a tiller for 5 days. It cost $59 per day to rent the tiller. She also buys a rake for $3 l. By how much did her gift card decrease by
Answers
Answer:
90 the answer is 90
Answer:
$250
Step-by-step explanation:
We can make a pretty simple equation to help us solve this. If the tiller costs $59 for each day and she uses it for 5 days, the first step of our equation would be (59 x 5). Then she buys a rake for 3 dollars, that is adding to the equation
(59 x 5) + 3
Fist solve what is inside the parentheses. 59 x 5 = 250
250 + 3 = 250

x=103 degrees
y=113 degrees
Explanation:
All the angles in a triangle add up to 180 degrees, so to find the measurement of angle x, we can use this equation and solve:
x=180-23-54
x=180-77
x=103
To find angle y, we need to understand that a straight line also has an angle of 180 degrees. This means we need to subtract the angle that is next to angle y from 180 to get angle y.
However, to find that angle that is next to angle y, we need to do the same thing we did above and find the angles of the triangle.
First, we find the angle next to x using this expression:
180-x
=180-103
=77
And now we find the measurement of the angle next to angle y:
180-77-36
=103-36
=67
And now we find angle y:
180-67
=113
Therefore, y=113 degrees
