Before recess, Marcy has math class for 1 hour and 50 minutes. Recess lasts for 30 minutes and ends at 11:55 A.M. What time does

Temka [501]

Answer:

Marcy's math class starts at 9:35.

Step-by-step explanation:

11:55

-50 = 11:05 This gets rid of 50 minutes of math class.

11:05

-30 = 10:35 This gets rid of the 30 minutes of recess.

Now subtract one more hour to subtract the remainder of math class, and you get 9:35. Marcy's math class starts at 9:35.

Patrick is driving form Sydney to Canberra. He travels for 288km trip in 4 hours. What's his average speed?

nika2105 [10]

Answer:

v = 72 km/h

Step-by-step explanation:

Given that,

The distance covered by the Patrick, d = 288 km

Time taken, t = 4 hours

We need to find the average speed of Patrick. We know that the average speed of an object is equal to the total distance covered divided by total time taken. Let it is v. So,

$v=\dfrac{d}{t}\\\\v=\dfrac{288\ km}{4\ h}\\\\v=72\ km/h$

So, his average speed is equal to 72 km/h.

Find the distance between the points (2, 7) and (-6, -2).

maw [93]

Answer:

Approximately 12.04 units.

Step-by-step explanation:

The find the distance between any two points, we can use the distance formula, which is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

We have the points (2,7) and (-6,-2). Let's let (2,7) be (x₁, y₁) and let's let (-6, -2) be (x₂, y₂). Substitute:

$d=\sqrt{(-6-2)^2+(-2-7)^2$

Subtract:

$d=\sqrt{(-8)^2+(-9)^2$

Square:

$d=\sqrt{64+81}$

Add:

$d=\sqrt{145}$

Approximate

$d=\sqrt{145}\approx12.04$

So, the distance between (2,7) and (-6,-2) is approximately 12.04 units.

And we're done!
