same for the length, 33cm is 3 timer larger
also sorry if its the other way around, i just call the ones that are like "______" length
Answer:
50 km/h
Step-by-step explanation:
Before the speed adjustments, their speeds were in the ratio 3:2. The difference in their speeds was 10 + 10 = 20 km/h, corresponding to a difference of 3-2 = 1 ratio unit.
Hence the faster car was traveling at 3×(20 km/h) = 60 km/h, and the slower car was traveling at 2×(20 km/h) = 40 km/h. After the speed adjustments, both cars are traveling at 50 km/h.
The first five terns of the sequence are - 1,4,1,4,1
<h3>What is a sequence?</h3>
A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. It has members, just like a set does. The length of the sequence is determined by the number of items.
an = 5 - a n-1
a1 = 1
a2 = 5 - (1) = 4
a3 = 5 - (4) = 1
a4 = 5 - (1) = 4
a5 = 5 - (4) = 1

Answer:
7.
Step-by-step explanation:
plug 27 in as y as y = 27.
3x - 1/9(27) = 18
3x + -3 = 18
add 3 on both sides
3x -3 + 3 = 18 + 3
3x = 21
x = 7
