Answer:
6.99 meters
Step-by-step explanation:
For this we have to use subtraction:
So if the second jump was .13 meters longer then the first and we know the second jump was 7.12 meters, we have to subtract 7.12 by .13 to get the length of his/her's first long jump. So our equation is 7.12-.13=length of first jump. So we end up getting 6.99=length of first jump.
Hope this helps! :D
Answer:
Step-by-step explanation:
To calculate the total surface area, you first need to calculate the surface area of one of the 4 triangles and multiply that by 4.
We can solve this two ways (I would recommend using 2).
1)
Using herons formula:
a, b, c = different sides of the triangle (length)
s = (a + b + c) / 2
a = 
If we input values:
a = b = c = 6.5m
s = (3 * 6.5) / 2 = 9.75
which is about 18.29478 (exact answer:
)
18.29478 * 4 = the entire area = 73.17912 m^2
exact whole area: 
2)
Each of the four triangles can be divided into 2 more triangles.
(2 * 4 = 8 = total amount of new small triangles)
How we calculate the area of one of the new small ones:
(h * w) / 2 = a
h = 5.6m
w = (width of one of the four triangles width divided by 2) = 3.25m
3.25m * 5.6m = 18.2m^2
18.2m^2 / 2 = 9.1m^2
There are 8 of the new small triangles in the biggest triangle made up of four smaller ones.
So if we take 9.1m^2 * 8, we get the total area!
Total area: 72.8m^2

Answer:
(16-7)x4
Step-by-step explanation:
You put 16-7 in parenthesis so it means to do it first, then multiply by 4.
Answer:
We are given that the pyramid has a square base that is inscribed in the circular base of a cone.
" To inscribe something means to draw (a figure) within another so that their boundaries touch but do not intersect "
Hence we have to draw a figure such that the vertices of the square base of pyramid touch the points on the circle which is a base of a circular cone and also the top of the pyramid touches the top of the cone.
The figure of this question is attached to the answer.
5/6=.83
1/6=-.16
.83*.16= -0.1328
