Answer:
10/3 minutes
Step-by-step explanation:
12 minutes to run 6 times is the same as 2 minutes to run once (ratios)
so it takes 2 minutes to run once around a 600 m track
so 2 minutes/600m = x minutes/1000m
x = 2/600 * 1000 = 20/6 = 10/3
Answer:
6:8 compares the number of tiger shark teeth to sand shark teeth.
Step-by-step explanation:
Ratios, in mathematics, is a way to compare two or more numbers in relation to their sizes. According to the question, Christian collected 18 different shark teeth. He found out that the tiger shark teeth were 6, sand shark teeth were 8, hence the remaining 4 shark teeth would be for bull shark.
In order to compare the number/size of the different shark teeth to one another, we use ratios. Hence, if we say 6:8, it means that the proportion of the tiger shark teeth to the sand shark teeth is 6 to 8. This also means that the tiger shark teeth is 6/8 of the sand shark teeth.

Answer:
y = 2x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
6x - 3y = 15 ( subtract 6x from both sides )
- 3y = - 6x + 15 ( divide all terms by - 3 )
y = 2x - 5 ← in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
To find c substitute (- 2, 4) into the partial equation
4 = - 4 + c ⇒ c = 4 + 4 = 8
y = 2x + 8 ← equation of parallel line
Answer:
1) sum=6, product=-3/2
2) sum=-8,product=3
Step-by-step explanation:
For the first question, you'd divide the equation to make the co efficient of X square 1
Then compare to the equation you wrote above
For the second, the co efficient of X square is already 1. So just compare it to the equation above
