Mike is biking to catch up with his sister who is already 1200 yards ahead of him. If he bikes at a speed of 600 yards per minut

Answer:

8 minutes.

Step-by-step explanation:

Let m represent number of minutes.

We have been given that Mike is biking to catch up with his sister who is already 1200 yards ahead of him. His sister is biking at a speed of 450 yards per minute.

So total distance covered by Mike's sister after m minutes would be $450m+1200$ .

Mike bikes at a speed of 600 yards per minute, so total distance covered by Mike in minutes would be $600m$ .

Now, we will equate both expressions to find minutes at which both distances will be equal as:

$600x=450m+1200$

$600x-450m=450m-450m+1200$

$150m=1200$

$\frac{150m}{150}=\frac{1200}{150}$

$m=8$

Therefore, it will take after 8 minutes for Mike to catch his sister.

Insert grouping symbols so that the given expression has a value of 34. 14 + 10 – 6 • 8 – 3

Naily [24]

The correct answer is D. 14 + (10 – 6) • (8 – 3).

That's because in each of the other answers, we are subtracting a greater and greater number. But in this version, we are first completing the parenthesis, which gives us the following.

14 + (10 – 6) • (8 – 3)

14 + (4) • (5)

Now we complete the multiplication.

14 + 20

And we end with the addition.

Answer:

The answer is D.

Step-by-step explanation:

The plots are going down to the right, showing a negative slope. The plots are do not have the same x-axis/domain, so there is a linear asociation between the two.
