An airplane took 5 hours to travel 3,420 kilometers.how many kilometers did the plane travel in one hour

tino4ka555 [31]

Answer:

684 Hours.

Step-by-step explanation:

If the plane travelled that distance in 5 hours, then all you need to do is divide the distance by 5 to get the distance travelled in one hour. This is obviously presuming that the speed travelled was constant or that this is an average figure.

3420/5 = 684.

I need to find the area of the shaded region, but I need detailed steps

olasank [31]

The shaded region is a parallelogram.

The formula for the area of any parallelogram is $A=bh$ .

The base of the parallelogram is 2 meters long (given).

The height of the parallelogram is 9 meters (do not be fooled by the unnecessary information of 14 meters)
The height is 9 meters because the height has to be perpendicular to the base. Thus, the side length must be 9 meters.

Multiply them together.

$2 \times 9 = 18$

The area of the parallelogram is 18 square meters.

What is the surface area of this prism? A. 120 cm2 B. 122 cm2 C. 240 cm2 D. 184 cm2

Aneli [31]

Here is how to get the Surface Area of a triangular prism.
First you must find their areas first then multiply it by 2 (because it has 2 faces) except for the base, since it has a triangular base.
A = bxh/2 A = 15 m x 30 m A = 30 m x 18 m
 = (18 m x 12 m )/2 = 450 m^2 = 540 m^2
 = 216 m ^2/2
 = 108 m^2
Add all the faces:
SA = 2 (108 m^2) + 2 (540 m^2 ) + 450 m^2
= 216 m^2 +1080 m^2 + 450 m^2
= 1,746 m^2
The answer is not found in your choices. The attached picture is also showing m (meter) as the unit used not cm.....so I guess you got the wrong choices.

What is the value of x?

Rashid [163]

Answer:

X=98°

Step-by-step explanation:

53° + 45° = 98

98-180= 82

every triangle is always equal o 180°

so... 53°+ 45°+ 82° = 180

to find x you need to subtract 82 from 180 which is 98

remember its important to find the inner degree before the outer.
