Answer:

Step-by-step explanation:
We remove the bracket and rearrange the numbers to add them. Only similar variables can be added together.

Answer:
60 ; 5220
Step-by-step explanation:
A) From the horizontal bar chart provided, it could be inferred that 85 people spell the word 'weird' correctly. The graph is scaled on a fixed interval of 10. Hence, the midpoint of 10 = 5
(80 + 5) = 85
B) In a group consisting of 8719 randomly selected people estimate how many more people can correctly spell weird than inoculate
From the graph :
85 per 100 could spell weird correctly while,
About 25 per 100 could spell inoculate correctly.
Difference In number per 100 people
(85 - 25) = 60 people per 100
We could round 8719 to the nearest 100 = 8700
Number of 100's in 8700 = 8700/100 = 87
(87 × 60) = 5,220 people
B: 9.25
12/19=5.75/x
X=9.10 but least amount which is 9.25
Answer:
34.576 = 30 + 4 + 0.5 + 0.07 + 0.006
Answer:
2:3
Step-by-step explanation:
First, create the ratio by putting the numbers together:
There are 4 red and 6 blue marbles:
4:6
Since both of these are divisible by 2, it can be simplified:
4:6
2:3
So, the ratio of red marbles to blue marbles is 2:3
