Answer:
B
Step-by-step explanation:
To find the distance we need to add the numbers:
2 - (-3/4) = 2 + 3/4
5^3 = 5 * 5 * 5 = 125
7^-2 = 1 / 7^2 = 1 / 49
51^1 = 51
Find how much the tree grew by subtracting the original height from the new height:
49 1/2 - 38 1/2 = 11 feet.
To find the average yearly rate, divide the amount the tree grew by the number of years:
11 feet / 5 1/2 years = 2 feet per year.
Vcylinder-vcone=vair
vcylinder=hpir^2
vcone=(1/3)hpir^2
vcylinder=16*pi*5^2=400pi
vcone=(1/3)12*pi*4^2=64pi
vylinder-cone=400pi-64pi=336pi
volume is 336pi cubic centimeters or aprox 1055.5 cubic cm
Hi!
These two triangles are similar, so the angle ACB = angle FED = 108. That also means that angle ABD = angle FDE = 48 = y. Sum of all three angles in a triangle is 180, so:
108 + y + 2x - y = 180
2x = 72
x = 36
y = 48
Hope this helps!
