the table shows the number of miles driven over time. express the relationship between distance and time in simplified form as a
unit rate. determine which statement correctly interprets this relationship.
2 answers:
Answer:
a. 51/1 your car travels 51 miles every one hour.
Step-by-step explanation:
finding the relationship between distance and time in mathematics means to divide the first one by the second one so lets do that:
as you can see the relationship between distance and time in this example is always 51 miles in 1 hour, so that is the answer to the question.
B answer is not rigth because the car traveled more than 204 and it's not a relationship between distance and time.
C answer is not rigth because the relationship is upside down
D answer is not rigth because 10 hours is not a relationship between distance and time

Check the picture below.
A)
well, we start off by making a table of values for the function, with a few "t" values, as you see in the picture, then graph those points to get the graph.
B)
at t = 0, h(0) = 98, and at t = 1, h(1) = 82, so it went from 98 to 82, for a difference of 16.
C)
at t = 1, h(1) = 82, and at t = 2 h(2) = 34, so it went from 82 to 34, for a difference of 48.
does it fall the same distance on both intervals? well, they're different, so nope.
It appears as if 12cm is half the length of the side so we can assume that the total length of one side is 24cm.
The area of a square is given by the equation where s is the length of the side.
A=576
The area of this square is 576cm2.
Hope this helps!
Answer:
see explanation
Step-by-step explanation:
(a)
Sum the parts of the ratio , 1 + 2 + 3 = 6 parts
Divide sum of angles in a triangle by 6 to find the value of one part of the ratio.
180° ÷ 6 = 30° ← value of 1 part of the ratio
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
Since there is an angle of 90° then the triangle is right.
(b)
The shortest side is the side opposite the smallest angle of 30°
Using the sine ratio and the exact value
sin30° = , then
sin30° = =
=
( cross- multiply )
2 opp = 19 ( divide both sides by 2 )
opp = 9,5
Shortest side in the triangle is 9.5 cm
