Answer: 1.) 180 cubic meters

2.) 302 square centimeters

3.) 16.33 centimeters

Step-by-step explanation:

1.) Volume of pyramid is bh/3

Base is 6×6 Height is 15/3

Multiply to get 180.

2.) Two sides are 5×11=55 each. Two sides are 6×11=66 each, and the two ends are each 5×6=30.

Add 55+66+30=151 then multiply 151×2=302.

3.) V=bh.

Triangular base is ab/2. Given a is 10 and base (edge of square side) is 12.

10×12/2= 60. Divide that into the given Volume: 1080cm^3

1080÷60= 16.33cm^2

Calculate the distance between the points L=(-4,-1) and E =(3, 7) in the coordinate plane.

BaLLatris [955]

Answer:

10.6301458127

Step-by-step explanation:

Distance between any two points (x1, y1) and (x2,y2) on a coordinate plane is expressed by the formula = $\sqrt{(x1-x2)^2 + (y1 - y2)^2} \\$

given L=(-4,-1) and E =(3, 7

substituting value of coordinates in equation $\sqrt{(x1-x2)^2 + (y1 - y2)^2} \\$

we have

$\sqrt{(-4 - 3)^2 + (-1 - 7)^2} \\=>\sqrt{(-7)^2 + (-8)^2} \\=>\sqrt{49 + 64} \\=>\sqrt{113} \\=>10.6301458127$

Therefore the distance between the points L=(-4,-1) and E =(3, 7) = 10.6301458127
