What is the average speed of an
automobile trip of 275 miles that
began at 7:30 in the morning and
ended at 12:30 in the afternoon
The average speed of an automobile is a 55 miles per hour.
According to the statement
We have to find that the value of the average speed of an automobile.
So, For this purpose, we know that the
The average speed is the total distance traveled by the object in a particular time interval.
From the given information:
automobile trip of 275 miles that began at 7:30 in the morning and ended at 12:30 in the afternoon
Then
The total distance covered = 275 miles
And
The total time taken = From 7:30 in the morning to 12:30 in the afternoon
Then
The total time taken = 5 hours,
Then
Average speed = total distance covered / total time taken
Average speed = 275 miles / 5 hours
Then
Average speed = 275 / 5
Average speed = 55 miles per hour.
So, The average speed of an automobile is a 55 miles per hour.

Area of triangle A is 72.2 cm square.
Here, we are given that triangles A and B, as shown in the figure are congruent to each other.
They are also both right angle triangles.
The length of the hypotenuse of A is 17cm
and the height of triangle be = 12cm
But as these two are congruent,
height of triangle A will also be 12cm.
Now, according to Pythagoras theorem,
[tex]hypotenuse^{2} = base^{2} +height^{2}[/tex]
[tex]17^{2}[/tex] = [tex]12^{2}[/tex] + [tex]base^{2}[/tex]
289 = 144 + [tex]base^{2}[/tex]
[tex]base^{2}[/tex] = 145
base = 12.04
Thus, the area of the triangles = 1/2 * base height
= 1/2 x 12 x 12.04
= 72.2
Thus the area of triangle A will be 72.2 cm square.

Write each equation in slope-intercept form. Then find the slope and y -intercept of each line. -3 x+2 y=7
The slope-intercept form of the given equation of a line is: y = 3/2(x) + 7/2 The slope here, is 3/2 and y-intercept is 7/2.
What is the equation of a line to the curve?A line's equation has the standard form ax + by + c = 0. Here, the variables are x and y, the coefficients are a and b, and the constant term is c. It is a first-order equation with the variables x and y. The coordinates of the point on the line shown in the coordinate plane are represented by the values of x and y.Now,
The slope-intercept form of an equation of a line is given by: y = mx + c, where m = slope of the line and c = y-intercept of the line.
Transforming the given equation of the line: -3x + 2y = 7
=> 2y = 7 + 3x
=> y = 3/2(x) + 7/2
On comparing it with y = mx + c, we get that: m (slope) = 3/2 and c = 7/2 (y-intercept).
Hence, The slope-intercept form of the given equation of a line is: y = 3/2(x) + 7/2. The slope here, is 3/2 and y-intercept is 7/2.

evaluate the expression 13 divided by (2.5 - |-3 1/8|) times 3 to the third power
Answer: -561.6
Step-by-step explanation:
First, recall PEMDAS (Parenthesis, Exponents, Multiply, Divide, Add, Subtract)
In the equation, we need to work through (2.5 - |-3 1/8|) first.
The absolute value of |-3 1/8| is 3 1/8
We change 3 1/8 to a decimal
3 1/8 = 3.125
Now Subtract (2.5 - 3.125)
This equals -0.625
Next, divide 13 by -0.625
13 ÷ -0.625 = -20.8
Then, multiply -20.8 by 3³
3³ = 27
So -20.8 × 27 = -561.6

If g+9=4 and h-8--3, what is the

Answer:
g + h = 6
Step-by-step explanation:
We are told that:
• [tex]g + 9 = 4[/tex]
• [tex]h- 8=3[/tex].
To calculate the value of g + h, we have to rearrange the above equations to make g and h their respective subjects:
• [tex]g + 9 = 4[/tex]
⇒ [tex]g + 9 - 9 = 4 - 9[/tex] [Subtracting 9 from both sides]
⇒ [tex]g = \bf -5[/tex]
• [tex]h- 8=3[/tex]
⇒ [tex]h - 8 + 8 = 3 + 8[/tex] [Adding 8 to both sides]
⇒ [tex]h = \bf 11[/tex]
Now that we know the values of g and h, we can find the value of g + h:
[tex]g + h[/tex]
[tex]= -5 + 11[/tex]
[tex]= \bf 6[/tex]
Therefore the value of g + h is 6.
