Answer:
The error with mark’s work is that a negative times a negative will give a positive. So -3 times -5 is +15 not -15. Then 15 times -2 will get you -30.
Answer:
There are a few different answers, because distance doesn't translate to speed.
Speed: 40 mph = 58.66142 fps
Distance: 40 miles = 211,200 feet
Hope that this helps!
Percent formula : is/of = %/100
% = n
is = 23
of = 94
now we just sub our numbers into the formula
23/94 = n/100 <===
so initially the paper is in full piece.
it is cut into half, which makes into 2. this is pattern 1.
then the halves is further divided in to 2.
then the total becomes 4. then the four pieces are cut into halves, which makes the total of 8 pieces, that is pattern 3..
is if we see the pattern it is a geometric progression.
Tn=ar²-¹ where the r is common ratio
and a is the first term. the question mentioned repeat 15 times.
1. 2
2. 4
3. 8
4. 16
4÷2=2 the common ratio.
So T(15)= 2×2¹⁵-¹
2×2¹⁴
2¹⁵
32768 pieces
please mark brainliest.
