Yeah I don’t know but have someone else
Answer:
1. N4 = a
2. N8.25 = b
Step-by-step explanation:
1000 litre =N3
Each additional 100 litres = 5 k
100 litres
2000 litres
100 litres =5k
2000 litres = x
100x =5×2000
100x =10,000
Divide both sides of the equation by 100
x = 100k
100 Kobo = N1
x =N1
N3+N1 =N4
2. First ten words cost N6
Each additional word cost 45 k
1= 45k
5=x
x = 5×45
= 225 Kobo
100 Kobo = 1 Naira
225 Kobo = x
x = N2.25
N6 + N2.25
x = N8.25 = B
A scientist has collected the following data on the population of a bacteria colony over a thirty-minute period:
5 minutes: 78,000
10 minutes: 234,000
15 minutes: 657,000
20 minutes: 1,784,000
25 minutes: 5,040,000
30 minutes: 14,980,000
Which type of graph would be best to use to display the growth of the colony?
A.) a bar graph
B.) a circle graph
C.) a histogram
D.) a line graph
An bar graph suits the best in this type of study because we can easily understand the growth and decrease of that particular thing which is being studied.
Answer is 105 degrees.
Explanation:
Given two parallel lines AB and CD and a transversal cutting the two lines.
We know that when a transversal cuts two parallel line,
i) corresponding angles would be equal
ii) Interior angles total to 180
iii) alternate angles are equal.
In the picture given we have corresponding angles as
(2,6) . Hence angle 2 = angle 6.
Angle 6 = 75 (given)
Hence angle 2 =75.
Angles 1 and 2 are supplementary because they form a linear pair.
Hence angle 1 = 180-75
Angle 1 =105
The word form of 3.4 is three and four-tenths. Expanded form is 3+.4.
