40 miles will he have after 85 minutes of driving .
Given :
austin is driving to san francisco, suppose that the distance to his destination in miles is a linear function of total driving time. has 67 miles to his destination after 49 minutes of driving . He has 47.5 miles to his destination after 75 minutes of driving .
slope = y2 - y1 / x2 - x1
m = 47.5 - 67 / 75 - 49
= -19.5 / 26
= -3/4
= -0.75
Use the point slope y - y1 = m(x - x1)
y - 67 = -.75 ( x - 49 )
y - 67 = -.75x + 36.75
y = -.75x + 36.75 + 67
y = -.75x + 103.75
x = 85
y = -.75(85) + 103.75
y = -63.75 + 103.75
y = 40 miles

Q. Find the measure of the angle indicated in the following parallelogram.
The measure of the angle S is 112° in the following parallelogram.
What is parallelogram?
A parallelogram is a geometric object with sides that are parallel to one another in two dimensions. It is a form of a polygon with four sides (sometimes known as a quadrilateral) in which each parallel pair of sides have the same length. In a parallelogram, the opposing sides are of equal length, and the opposite angles are of equal size. A parallelogram has adjacent angles that add up to 180 degrees.
Given, ∠T= 11x + 2
∠V = 10x + 8
From the above definition, opposite angles are equal
So, ∠T = ∠V
or, 11x + 2 = 10x + 8
or, 11x - 10x = 8 - 2
or, x = 6
∠V= 10x + 8 = 10*6 + 8 = 68 degree
From the above definition, adjacent angles add up to 180 degrees
∠V + ∠S = 180°
or, 68° + ∠S =180°
or, ∠S = 180° - 68° = 112°
Hence, the measure of the angle S is 112°.

You had a bag of fruit snacks that you shared with 2 friends. Each of you got at least 6 fruit snacks. The inequality X÷326 models this situation. Solve the inequality to find the number of fruit snacks that were in the bag. There were at least fruit snacks in the bag.
The solution of the inequality is greater than or equal to 18. The number of fruit snacks that were in the bag is 18.
What is the inequality?
In mathematics, inequalities specify the relationship between two non-equal values. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
Given inequality is
X÷3 ≥ 6
Rewrite left side expression:
X/3 ≥ 6
Multiply both sides by 3:
X ≥ 6 × 3
X ≥ 18
The value X is greater than or equal to 18.
Therefore the number of fruit snacks that were in the bag is 18.

A laser rangefinder is locked on a comet approaching Earth. The distance g(x) , in kilometers, of the comet after x days, for x in the interval 0 to 42 days, is given by g(x)=300,000csc(π42x) .
a. The blue line represents g(x) = 250,000csc(π30x).
b. g(5) = 25,000 km. This is the distance of the comet from Earth after 5 days.
c. The minimum distance between the comet and Earth is 250,000 km, which occurs when x = 0. This corresponds to the constant csc(π30x).
d. The equation has a vertical asymptote at x = 30/π.
Write the solution to following questions:a. Graph the value of x on the range [0,35].b. Analyze g(5) and explain the results.c. What is the shortest path the comet must take to reach Earth? When does this take place? What equation constant does this match up to?d. Find any vertical asymptotes and explain their significance.a. Graph g(x):
To graph g(x), we can plot several points on the interval [0,35] and then connect them to form a graph of the function. For example, we can plot the points (0,250,000), (5,50,000), (10,25,000), (15,16,667), (20,12,500), (25,10,000), (30,8,333) and (35,7,143). Connecting these points will give us a graph of the function g(x).
b. Evaluate g(5):
The value of g(5) can be found by plugging in x = 5 into the equation: g(5) = 250,000 csc(π30*5) = 50,000 km. This means that after 5 days, the comet will be 50,000 km away from Earth.
c. Minimum distance between the comet and Earth:
The minimum distance between the comet and Earth can be found by taking the derivative of the equation and setting it to 0.
d. Vertical Asymptotes:
The vertical asymptotes of g(x) occur at x = 0 and x = 30. This means that the comet approaches an infinitely large distance from Earth at x = 0 and x = 30.

The equation of slope intercept form is y = 3/2x + 12 if a line passes through the point (-6,3) and has a slope of 3/2.
Define slope intercept form.The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation. The slope, m, is a measure of how steep a line is. The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables.
Given
A line passes through the point (-6,3)
and has a slope of 3/2
Slope intercept form

Which property justifies the statement below? X(y+5)=xy+5x
Find the solution of this system of equations x+3y=-33 -4x+5y=-38
The solution for the given system of equations is:
x = -63
y = 10
How to solve the system of equations?Here we want to solve the following system of equations:
x + 3y = -33
-4x + 5y = -38
To solve the system by substitution, we first need to isolate one of the variables in one of the equations, I will isolate x on the first equation so we get:
x = -33 - 3y
Now we can replace this in the other equation, so we will get:
-4x + 5y = -38
-4*(-33 - 3y) + 5y = -38
Now we can solve this for y, we will get:
-4*-33 - 4*-3y + 5y = -38
132 + 12y + 5y = -38
17y = -38 - 132
17y = 170
y = 170/17 = 10
y = 10
The value of x is given by:
x = -33 - 3y
x = -33 - 3*10 = -63
So the solution is x = -63 and y = 10.

3. If the aspect ratio of a tire is 50%, width 10 inches, and the rim diameter is 19 inches, what is the tire diameter?
a. 59in b. 35.8in
d. 49in
4. The standard print paper is 11" by 8.5 in. What is the aspect ratio of a standard print paper?
a. 11:8
c. 8.5
c. 29 in
b. 22:17
d. 11
3) The tire diameter using the aspect ratio is; 29 inches
4) The aspect ratio of a standard print paper is; 22:17
How to solve aspect ratio problems?The aspect ratio is defined as the relationship between the width and height.
Now, in this case, the aspect ratio must be in whole numbers and not decimals and as such we can solve as follows;
3) We are told that the aspect ratio of a tire is 50%.
Thus, the aspect ratio is; 50/100 = 1/2 or 1:2.
Now, we are told that width 10 inches, and the rim diameter is 19 inches, then it means that the tire diameter = 10/2 + 19 + 10/2 = 29 inches
4) The standard print paper is 11" by 8.5. This can also be written as;
11 by 17/2 or 11 * 2 : 17
= 22:17
This then gives us the aspect ratio.

Age of Senators The average age of senators in the 108" Congress was 57.5 years. If the standard deviation was 11.5 years, find the -scores corresponding to the oldest and youngest senators of age 87 and 44. Round scores to two decimal places. find the z-score corresponding to the oldest senator of age 85 is
The z-scores correspond to the oldest and youngest senators of ages 87 and 44 are 2.57 and -1.17. The z-score corresponding to the oldest senator of age 85 is 2.39.
A Z-score is a metric that quantifies how closely a value relates to the mean of a set of values. The formula to calculate this score [tex]z=\frac{x-\mu}{\sigma}[/tex]. Where z is the z-score, x is the observed value, μ is the sample mean, and σ is the sample standard deviation.
Given μ = 57.5 and σ = 11.5.
When x = 87, the z-score value is,
[tex]\begin{aligned}z&=\frac{87-57.5}{11.5}\\&=2.57\end{aligned}[/tex]
When x = 44, the z-score value is,
[tex]\begin{aligned}z&=\frac{44-57.5}{11.5}\\&=-1.17\end{aligned}[/tex]
When x = 85, the z-score value is,
[tex]\begin{aligned}z&=\frac{85-57.5}{11.5}\\&=2.39\end{aligned}[/tex]
The required answers are 2.57, -1.17, and 2.39.
