Tom traveled for 4 hours by train and 4 hours by plane, for a total trip time of 8 hours.
We have,
Let's call the number of hours Tom traveled by train t.
Since he traveled the same number of hours by plane, he also traveled for t hours at 275 mph.
The total distance he traveled is given by the sum of the distances traveled by train and by plane:
Distance by train = 50t
Distance by plane = 275t
Total distance = 1300
So we can set up the equation:
50t + 275t = 1300
Simplifying and solving for t, we get:
325t = 1300
t = 4
Therefore,
Tom traveled for 4 hours by train and 4 hours by plane, for a total trip time of 8 hours.

we can simplify each term within the parentheses before multiplying them together.
Let's simplify each term step by step:
\left( \frac{16}{9} \right)^{2/3}:
To simplify this term, we raise the fraction to the power of 2/3.
\left( \frac{16}{9} \right)^{2/3} = \left( \left( \frac{2^4}{3^2} \right)^{1/3} \right)^2 = \left( \frac{2^{4 \cdot 1}}{3^{2 \cdot 1}} \right)^2 = \left( \frac{2^4}{3^2} \right)^2 = \left( \frac{16}{9} \right)^2 = \frac{16^2}{9^2} = \frac{256}{81}

what is the relationship between the area of a rectangle and a parallelogram
Answer: The relationship between the area of rectangle and area of parallelogram is that they both are equal in area.
Step-by-step explanation:
parallelogram is formed when two parallel lines intersects other two parallel lines and rectangle is a type of parallelogram in which the intersecting lines intersects at right angle.
rectangle and parallelogram shares the same property and If we consider same base and same parallel lines then the area of parallelograms formed is always equal and as I mentioned above rectangle is also a parallelogram.
hence area of rectangle is equal to the area of parallelogram in same base and same parallel lines.

b. How many 16 oz jars and how many 28 oz jars of peanut butter were donated to the food bank? Explain or show how you know.
35 16 oz jars and 47 28 oz jars of peanut butter were donated to the food bank by solving equation
Let x be the number of 16 oz jars of peanut butter collected, and y be the number of 28 oz jars of peanut butter collected.
The system of equations that represents the constraints in this situation is:
x + y = 82 (total number of jars collected)
16x + 28y = 1876 (total amount of peanut butter collected in ounces)
b. To solve for the number of 16 oz jars and 28 oz jars of peanut butter donated to the food bank
we need to solve the system of equations from part (a). One way to do this is to use elimination:
Multiplying the first equation by 16, we get:
16x + 16y = 1312
Subtracting this equation from the second equation, we get:
12y = 564
Dividing both sides by 12, we get:
y = 47
Substituting this value of y into the first equation, we get:

31. There are two gears that are connected to each other. One gear has 20 teeth and the other gear has 10 teeth. If the bigger gear turns around 5 times, how many times will the smaller gear turn?
10 times will the smaller gear turn.
What is the ratio?
The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Since the smaller gear has 10 teeth and the bigger gear 20, the smaller gear will turn twice for every rotation of the larger gear (20/10=2).
Therefore, if the larger gear rotates five times, the smaller gear will rotate two times five times, or ten times. The smaller gear will thus rotate 10 times.
So, if the bigger gear turns around 5 times, the smaller gear will turn around 5 x 2 = 10 times.
Therefore, the smaller gear will turn 10 times.

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (- 4, 0) and (0, 2).
Now,
Since, The equation of line passes through the points (- 4, 0) and (0, 2).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (2 - 0) / (0 + 4)
m = 2 / 4
m = 1/2
Thus, The equation of line with slope 1/2 is,
⇒ y - 0 = 1/2 (x + 4)

Answer:(1,−7π/4)
Step-by-step explanation:
Note that the point is on the circle whose radius is labeled 1, so r=1 or −1. Of the choices available, only an angle of −7π4, drawn from the positive x axis plots at the point A. So θ=−7π4, and r must be positive, as the angle is measured from the positive x axis. Thus, the polar coordinates are (1,−7π4).
