Step-by-step explanation:
we have 8 equally "heavy" batches.
one weighs 3.9 × 10^-10 g
so, the total sample then weighed
8 × 3.9 × 10^-10 = 31.2 × 10^-10 = 3.12 × 10^-9 g
Answer:
Graph B
This is because of the vertical line test. Say you were to draw a vertical line that stretches through the whole graph. If this line you draw passes through more than two points of the same line/function/whatever b is, it is not a function.
Answer:
-5.25
Step-by-step explanation:
-3(-a+2)=7a+15
=>3a-6=7a+15
=>-15-6=7a-3a
=>-21=4a
=>a=-21/4=-5.25
hope this helps please mark as brainliest:)

Answer:
Length of longer length=132 inches
Length of shorter length=33 inches
Step-by-step explanation:
Step 1: Determine total length of pipe
Total length of pipe=165 inches
Step 2: Derive expression for all the lengths
We can express all these lengths as follows;
L=l1+l2
where;
L=total length
l1=length of longer piece
l2=length of shorter piece
but;
length of longer piece=4×length of shorter piece
replacing;
l1=4l2
replacing;
L=165
l1=4×l2
165=l 2+4 l2
5 l2=165
l2=165/5
l2=33 inches
l1=length of longer length=33×4=132 inches
l2=length of shorter length=33 inches
