"63. -2

1 answer:

4 0

E. If you think about it, combining -2 and 4 makes 2, and combining -6 and 8 makes two as well. That means that there's a value of two more for each two terms. Since this goes up in an interval of 2, and there's a total of 24 at the end, there's a total of 12 numbers and 6 of them are positive. Since it goes up 2 for every positive number, that means the total is 12. Sorry if I was confusing, I can clarify if you need it.

A sailboat leaves port and sails 12 kilometers west and then 9 kilometers north.

GarryVolchara [31]

Answer: The sailboat is at a distance of 15 km from the port.

Step-by-step explanation: Given that a sail boat leaves port and sails 12 kilometers west and then 9 kilometers north.

We are to find the distance between the sailboat from the port in kilometers.

Since the directions west and north are at right-angles, we can visualize the movement of the sailboat in the form of a right-angled triangle as shown in the attached figure.

The sailboat moves leaves the port at P and reach O after sailing 12 km west. From point O, again it moves towards north 9 km and reach the point S.

PS = ?

Using the Pythagoras theorem, we have from right-angled triangle SOP,

Thus, the sailboat is at a distance of 15 km from the port.

juin [17]

Hey there! :)

Answer:

x = 242 mm.

Step-by-step explanation:

Begin by setting up a proportion between the actual college building and the drawing.

$\frac{22mm}{9m} = \frac{x}{99m}$

Cross multiply:

99 × 22 = 9 × x

2178 = 9x

Divide both sides by 9:

2178/9 = 9x/9

x = 242 mm.

MrRissso [65]

Answer:

0.015 miles

Step-by-step explanation:

$1mile = 4min \\ 1mile = 240sec \\ 0.609km = 240sec \\ \frac{0.609}{24} = \frac{240}{24} \\ 10sec = 0.025km \\ 10sec = 0.015miles$
