Answer:
The constant of proportionality is 490
The jet will take 12 hours to travel 5,880 miles
Step-by-step explanation: The miles multiply by 490 each time.
490 x 12 is 5,880
The constant of proportionality is k = 490 and the equation is y = 490x where x is the number of hours and y is the total number of miles
The time required is 12 hours
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the distance of the aircraft be = x
Let the total time taken by the aircraft be = y
Let the constant of proportionality be k
when x = 1 ,
y = 490
So , the equation will be y = kx
Substituting the values in the equation , we get
y = 490x
when x = 2
y = 490 ( 2 )
y = 980
Now , the time taken by aircraft to travel 5,880 miles is
Substitute the value of y as 5880 in the equation , we get
5880 = 490x
Divide by 490 on both sides of the equation , we get
x = 5880 / 490
x = 12
Therefore , the time taken is 12 hours
Hence , the constant of proportionality is 490

3.5 times 4.9 using a area model
Answer:
17.15
Step-by-step explanation:
Find the the equation of the line passing through the points (3,3) and (4, 5)
Answer:
y = 2x - 3
Step-by-step explanation:
Given:
(3, 3) and (4, 5)
Solve:
Find the slope (m) between the two points:
m = (y2 - y1)/(y2 - 1)
(x1, y1) = (3, 3)
(x2, y2) = (4, 5)
m = (5 - 3)/(4 - 3)
= 2/1
m = 2
Slope-intercept form (y = mx + a):
y = 2x + a
To find a, plug in one of the points into the equation:
3 = 2(3) + a
3 = 6 + a
3 - 6 = a
a = -3
y = 2x - 3

which is closer to 0 3/8 or -1/3
Answer:
-1/3 is closer to 0
Step-by-step explanation:
3/8 is between 0 and -1/3. We need to determine if 3/8 is closer to -1/3 or closer to zero. Since -1/3 is smaller than 3/8, 3/8 is closer to -1/3. Since 3/8 is closer to -1/3, 3/8 rounded to the nearest -1/3 is -1/3.

30(30-x)=540 what is the value of x
Answer:
x = 12
Step-by-step explanation:
Original equation:
30(30 - x) = 540
Use distributive property
30 · 30 = 900
30 · (-x) = -30x
Plug these values back into the equation
900 - 30x = 540
Subtract 900 from both sides
-30x = -360
Divide both sides by -30
x = 12

Which equation is the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y=8/3
x?
HELP ASAP
Hi there!
[tex]\large\boxed{y = \frac{8}{3}x - \frac{2}{3}}[/tex]
A line parallel to y = 8/3x has a slope of 8/3, therefore:
Plug the given slope into the slope-intercept formula, along with the given coordinates to solve for the formula:
2 = 8/3(1) + b
2 = 8/3 + b
6/3 = 8/3 + b
6/3 - 8/3 = b
b = -2/3
Therefore, the equation in slope formula is:
y = 8/3x - 2/3
