SA pyramid+SA rectangular prism= total SA
Total SA= Area of the base+ area of the four rectangles+area of four triangles
Total SA= length^2+length*width*4+1/2(slant height)(length)*4
length=12, width=8, slant height=10
Total SA= (12)^2+4(1/2*12*10) +4(12*8)=768cm^2
so C is correct.
Answer:
Step-by-step explanation:
70(10/100)=7 broken cookies.
7/70=1/10 is the fraction broken
(70-7)/70=63/70 is the fraction remaining whole
1.36 < sqrt(2) < 2.45
1.65 < sqrt(3) < 2.34
1.65 < sqrt(4) < 2.34
1.65 < sqrt(5) < 2.34
1.53 < sqrt(6) < 2.46
feel like several of these are wrong sorry
A - b is NOT always natural. Eg 4 - 7 = -3 therefore not in the natural number set.
ab is always natural
a/b is NOT always natural. Eg 4/7
So the answer to the question is (b) only II must be a natural number answer.
Answer:
B) y=2x+3
Step-by-step explanation:
2x+3 2 is the slope it goes up two over one 2/1 or 2 and +3 is where the line intersects the y axis ( -3 would mean that the line intersected at -3 )
