Answer:
Average speed= 58.3 mi/hourStep-by-step explanation:
The average speed is defined as the total distance traveled divided by the total time taken.
from A to B
distance= 100 miles
speed= 50 mi/h
speed= distance/time
time= distance/speed
time= 100/50
time= 2 hours
from B to C
distance= 100 miles
speed= 70 mi/h
speed= distance/time
time= distance/speed
time= 100/70
time= 10/7 hours
Average speed= total distance/total time
total distance= 200 mile
total time= 2+10/7= (14+10)/7= 24/7
Average speed= 200/24/7
Average speed= 200*7/24
Average speed= 1400/24
Average speed= 58.3 mi/hour

The altitude of an airplane is represented in the graph below. A graph with time (minutes) on the x-axis and altitude (feet) on the y-axis. Points are at (0, 0), (20, 12,000), (40, 24,000), (60, 36,000), (80, 36,000), (100, 36,000), (120, 36,000), (130, 36,000), (140, 24,000), (160, 12,000), and (180, 0). Is the airplane’s altitude a function of time? Yes, because any input of time results in only one output of altitude. Yes, because the airplane increases and decreases in altitude at the same rate. No, because each output of altitude has more than one input of time. No, because the altitude is constant between 60 minutes and 130 minutes.

Answer:
A.) yes
Step-by-step explanation:
The formula for percentage increase I (given as a decimal) of an investment is I=S−P/P, where P is the purchase price and S is the sale price. You sell a stock at a price of $75, earning a percentage increase of 25%. What was the purchase price of the stock? Also solve the formula for P pls show steps
We are given the formula in the questions, so all we need to do is solve.
0.25 = 75-p/p
0.25 = 75 - p
0.25p + p = 75
1.25p = 75
1.25p/1.25 = 75/1.25
p = 60
Therefore, the purchase price was $60.

Ruben made 3.4 gallons of peach ice cream in his new ice cream maker. If there are 22.5 servings in a gallon, how many servings of ice cream did Ruben make? Ruben made servings of ice cream.
Answer:
Reuben made 76.5 servings of Peach ice cream
Step-by-step explanation:
Total gallons of peach ice cream made = 3.4 gallons
Number of servings per gallon = 22.5
This means that:
1 gallon = 22.5 servings
∴ 3.4 gallons = 22.5 × 3.4 = 76.5 servings
Therefore, Reuben made 76.5 servings of Peach ice cream
26-4s=9s solve the equation
Answer:
26=9s+4s
13s=26
s=26/13
s=2
Step-by-step explanation:
hope it is helpful for you if it is follow me
Answer:
s=2
Step-by-step explanation:
We are given the equation:
[tex]26-4s=9s[/tex]
and asked to solve. We want to find out what the unknown variable, s, is. Therefore, we must isolate s on one side of the equation.
First, let's get all the terms with s on one side of the equation. 4s is being subtracted from 26. The inverse of subtraction is addition. Add 4s to both sides of the equation.
[tex]26-4s+4s=9s+4s[/tex]
[tex]26=9s+4s[/tex]
[tex]26=13s[/tex]
s is being multiplied by 13. The inverse of multiplication is division. Divide both sides of the equation by 13.
[tex]26/13=13s/13[/tex]
[tex]26/13=s[/tex]
[tex]2=s[/tex]
[tex]s=2[/tex]
Let's check our solution. Plug 2 in for s and solve.
26-4s=9s
26-4(2)=9(2)
26-8=18
18=18
This checks out, so we know our solution is correct.
The solution to the equation 26-4s=9s is s=2.

Tracey paid $155 for an item that was originally priced at $520. What percent of the original price did Tracey pay? Around to the nearest tenth of a percent
Tracey paid approximately 29.8% of the original price for the item.
To find the percentage of the original price that Tracey paid, we can use the formula:
Percentage = (Amount Paid / Original Price) * 100
Let's plug in the given values:
Percentage = (155 / 520) * 100
Percentage = 0.2980769230769231 * 100
Percentage ≈ 29.8%
So, Tracey paid approximately 29.8% of the original price for the item.

3 lines are shown. A line with points A, F, D intersects a line with points B, F, E at point F. A line extends from point F to point C in between angle B F D. Which angle is a vertical angle with AngleEFD? AngleDFB AngleCED AngleBFC AngleAFB
Answer:
AngleAFB
Step-by-step explanation:
We know that vertical angles are angles that opposite each other when two lines intersect. They share a common point or vertex.
In the question, the angle opposite to angle EFD is angle AFB. This is because they share a common vertex.
Since they share a common vertex and are opposite to each other, angle AFB is the angle vertical to angle EFD.
So, the angle vertical to angle EFD is angle AFB.
Answer:
angle afb

What are subtraction and summation?Subtraction is the minus of any two numbers generally it gives a lower value than the digits which are going to be in the substrate.
A summation, which is the result of adding two or more numbers or quantities, is also known as a sum. A summation always has an integer number of terms. There might simply be two terms, but there might also be 100,000 or a million. Summations exist with an infinite number of parameters.
Given that
In option (B) job benifits $68,400 and job expenses $300 hence the remaining amount = $68,400 - $300 = $68100 which is greatest among all option
In option (A) the job beneifits $68,100 and job expenses $100 hence the remaining amount = $68,100 - $100 = $68000 which is less than A and in all option it is less

What are the x-intercepts of the graph of the function f(x) = x^2 + 4x – 12?
(-6,0). (2.0)
(2. -16). (0, -12)
(-6.0), (2, -16), (2, 0)
(0.-12).(-6, 0), (2, 0)
Answer:
(- 6, 0 ) , (2, 0 )
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
x² + 4x - 12 = 0 ← in standard form
(x + 6)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
x - 2 = 0 ⇒ x = 2
Thus the x- intercepts are (- 6, 0 ), (2, 0 )
What is the image of (9,0) after a dilation by a scale factor of 2 centered at the origin?
Answer:
(-18,0)
Step-by-step explanation:
Dilation involves changing the size of a point.
The image of (9,0) after a dilation by a scale factor of 2 centered at the origin is (18,0)
The point (P) is given as:
[tex]P = (9,0)[/tex]
The scale factor (k) is given as:
[tex]k = 2[/tex]
The image after a dilation centered at the origin is the product of the coordinates of the point and the scale factor.
So, we have:
[tex]P' = P \times k[/tex]
This gives
[tex]P' = (9,0) \times 2[/tex]
Expand
[tex]P' = (9\times 2,0\times 2)[/tex]
Evaluate the products
[tex]P' = (18,0)[/tex]
Hence, the image of (9,0) is (18,0)
