Step-by-step explanation:
An albatross is a large bird that can fly 400 kilometers in 8 hours at a constant speed. Using d for distance in kilometers and t for number of hours, an equation that represents this situation is d = 50t .
1. What are two constants of proportionality for the relationship between distance in kilometers and number of hours? What is the relationship between these two values?
2. Write another equation that relates d and t in this context.
Answer:
1. What are two constants of proportionality for the relationship between distance in kilometers and number of hours? What is the relationship between these two values?
The two constants of proportionality are 50 (for kph), and 50 (for distance traveled). The relationship between the two values is if either of them were to change it would affect the time. If the bird is flying at a constant rate, the distance determines the time needed to travel the distance, and if the bird were to fly at a different constant rate then the time would change as well, most likely lengthening.
2. Write another equation that relates d and t in this context.
If the albatross were to fly 90 kilometers with the variable T (# of hours) equaling 1.16667, what was the constant speed? (round your answer
to the nearest tenth)
The albatross's constant speed was: 77.1 kilometers per hour

.Evaluate the expression below.
(5.2 + 6.8) x - (25 ÷ 5) x
Answer:
7x
Step-by-step explanation:
(5.2+6.8)x-(25/5)x
(12)x-(5)x (Do the expressions in the parentheses, remember PEMDAS)
12x-5x (Multiply the terms in the parentheses by the value (x) outside of them)
7x (Subtract 5x from 12x)
The value of the equation is 7x
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A
Now , the value of the equation is
The "=" sign and terms on both sides must always be present when writing an equation.
The value of A = ( 5.2 + 6.8 ) x - ( 25 / 5 ) x
On simplifying the equation , we get
The value of A = ( 12 ) x - ( 5 ) x
Now , multiplying the coefficients of the equation with the variable x ,
The value of A = 12x - 5x
On subtracting 12x from 5x , we get
The value of A = 7x
Therefore , the value of A is 7x
Hence , The value of the equation ( 5.2 + 6.8 ) x - ( 25 / 5 ) x is 7x

Draw a Letter figure and translate it 3 units to the right, reflect in the y axis and rotate it 100
Can someone help do this plz
Answer:
We need to know what the letter is and where it was originally. Also is the 100 one hundred degrees or one hundred coordinates?
Step-by-step explanation:
1. For the translating part, simply pick one of the coordinates and move it three spaces to the right. Do this for each point.
2. For the reflecting part, count how many spaces each coordinate is from the y-axis, or vertical line. For the sake of example, let's say it is 3 spaces from the y-axis and started in the top left grid, or Quadrant III. You would then move said coordinate 3 spaces to the right in Quadrant IV, which is the top right.
I can't really help you on the rotating, since I don't know what form the 100 is in, but I hope this helped!

a = 6, b = 5, c = 3
a = 6, b = 3, c = 5
a = 1, b = 3, c = 6
a = 1, b = 5, c = 3
Answer:
a=6, b=3, c=5
Step-by-step explanation:

The values of a, b, and c for the correctly complete the division will be,
⇒ a = 6, b = 5, c = 3
What is Fraction?
A fraction is a part of whole number, and a way to split up a number into equal parts.
Given that;
The algebraic expression is,
''One-sixth divided by three-fifths = Start Fraction 1 Over a End Fraction times Start Fraction b Over c End Fraction''
Now,
Write the mathematical expression as;
⇒ 1/6 ÷ 3/5 = 1/a × b/c
Simplify the expression as;
⇒ 1/6 ÷ 3/5 = 1/a × b/c
⇒ 1/6 × 5/3 = 1/a × b/c
⇒ 5 / 6×3 = b / ac
After comparing, we get;
a = 6, b = 5, c = 3
Thus, The values of a, b, and c for the correctly complete the division will be,
⇒ a = 6, b = 5, c = 3
