Answer:
210 m
Step-by-step explanation:
Perimeter is the distance around the outside of a two-dimensional shape.
Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.
Christen ran around the soccer field, so she ran around the perimeter.
We can find the perimeter by adding all of the side lengths.
Perimeter=60 m+45 m+60 m+45 m
Christen ran 210m.
Answer:
a) 300
b) 900
Step-by-step explanation:
The length of the rectangle is 5 and the width is 3...
But since the rectangles are connected together, we could just work the problem like this:
5 x 2 = 10
_____________
3 x 5 = 15
15 x 2 = 30
The surface area of the shape is 10 x 30 = 300
______________________________________________
If the dimensions of the box were tripple, we would need to multiply the surface area by 3:
300 x 3 = 900
For the second question, the answer would be 900
Hope this helped you :-)
Answer:
Step-by-step explanation:
Rising 30 feet for every 400 feet of track is not a very large angle of elevation. We set this up as a right triangle to use right triangle trig to solve for the missing angle. The height is 30 and the hypotenuse is 400. The height is the side opposite the angle in question, and the hypotenuse is the hypotenuse! This is the sin ratio. Setting up the ratio using our info:

When you are looking for a missing angle measure, as we are here, use the 2nd-->sin buttons to find the inverse of sin, which looks like this:

Enter in the fraction 30/400 after the parenthesis and then hit enter to get the angle measure of 4.3 degrees.
