Yes, because you can simplify it to .2 which can be written as a fraction. Irrational numbers are those ones that keep going with an infinite string of numbers past the decimal.
Answer:
Option B ⇒ Area of base of each pyramid :
Option A ⇒ Volume of pyramid :
cm3
Step-by-step explanation:
One side of tile consists of 4 pyramids and since length of whole tile is x,
So, the base length of each pyramid = 
⇒ Area of base of each pyramid = side²
⇒ Area =

Volume of square based pyramid :

For 1. The correct Option is B
For 2. The correct option is A
The midpoints are (8,3) and (6.5,6).
<u>Step-by-step explanation</u>:
Midpoint formula = ((x1+x2)/2 , (y1+y2)/2)
(x1,y1) = (5,2)
(x2,y2) = (11,4)
Midpoint = ((5+11)/2 , (2+4)/2)
⇒ ((16/2) , (6/2))
⇒ (8,3)
(x1,y1) = (3,8)
(x2,y2) = (10,4)
Midpoint = ((3+10)/2 , (8+4)/2)
⇒ ((13/2) , (12/2))
⇒ (6.5,6)
<span>Determine which one of the following is the correct application of the change of base formula?
a)log3 14= log10 14/3
b)lo4 17= log10 4/ log10 17
c)log8 3= log10 3/log10 8
d)log9 32 = log10 32-log10 9
The change of base formula is as follows:
log to the base 10 of x
log to the base b of x = ----------------------------------
log to the base 10 of b
Compare this to answer choice C:
</span><span>c)log8 3= log10 3/log10 8 Here x = 3 and b = 8. This is the only correct choice.</span><span>
