Farm fresh because for $3.20 you get four pounds which is the better deal
Step-by-step explanation:
Cavalieri's Principle. A method, with formula given below, of finding the volume of any solid for which cross-sections by parallel planes have equal areas. This includes, but is not limited to, cylinders and prisms.
So, all you would do is use distribution.
For example: D is .5(x+3) = -3(x-.5)
you would do
.5 times x+3, which equals .5x+ 1.5
So, .5x+1.5=-3x+1.5
because -3*x-.5 is -3x+1.5.
Then, you would just get x by itself.
.5x+1.5=-3x+1.5
add 3 over to .5 = 3.5x;
subtract 1.5 over to 1.5 = 0
now you have 3.5x = 0
divide by 3.5 to get x by itself and you get zero.
x=0
When you substitute it in, you should have them both equal to each other. I hope this helps. :)
Answer:
A: 33.3 repeating
b: -3
c: -0.03
b=3
2:-4489/4 or -1122.25
3: g. -24
the last one is too blurry for me to figure out the answer. I hope what I gave you helps :3
Step-by-step explanation:
1) What is the slant height x of this square pyramid? Express your answer in radical form
sin 60=x/4--------> x=4*sin 60------> 4*(√3/2)-------> 2 √3 m
the answer Part 1) is 2 √3 m
2) The base of a regular pyramid is a hexagon. What is the area of the base of the pyramid?
[area of the base}=[area of hexagon]
[area of hexagon]=6*[area of triangle]
area of triangle
sin 60=a/14-------> a=(√3/2)*14-------> a=7√3 cm
cos 60=(b/2)/14--------> (b/2)=cos 60*14-----> (1/2)*14---------> (b/2)=7
base of triangle=2*7--------> b=14 cm
[area of triangle]=14*7√3 /2--------> 49√3 cm²
so
[area of hexagon]=6*[49√3]--------> 294√3 cm²
