Answer:
9.275 inches or 9 11/40
Step-by-step explanation:
current depth = beginning depth - inches swam up + inches swam down
8 3/4 - 2 3/5 + 3 1/8
= 9 11/40
A stone carver carved 37 statues in June. He will receive a bonus if he is able to carve 35% more carvings in
1 answer:
Answer:
50
Step-by-step explanation:
This is an example of a percentage increase.
To work out the percentage increase you would first have to convert the percentage into a decimal. You can do this by dividing the percentage of 35% by 100, this gives you 0.35. This is because percentages are out of 100.
The next step is to add 0.35 to 1, this gives you 1.35. This is because you are trying to work out the percentage increase.
Now to work out the minimum number of carving you would have to multiply the amount of 37 by 1.35, this gives you 49.95. This is because we are working out the percentage increase.
The final step is to round it, this gives you 50. This is because you need to make at least 49.95 and so you would round it up .
1) Divide 35 by 100.
2) Add 0.35 to 1.
3) Multiply 37 by 1.35.
4) Round.
50

Answer:
The answer is below
Step-by-step explanation:
A) i)
For Anna initially, she has $0 from making 0 envelopes. After making 400 envelopes she has $20. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (400, 20). Using the equation of a line:
The table is:
x: 200 400 600 800 1000
y: 10 20 30 40 50
ii)
For Jason initially, he has $0 from making 0 envelopes. For every 250 envelopes he has $10. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (250, 10). Using the equation of a line:
The table is:
x: 200 400 600 800 1000
y: 8 16 24 32 40
The graph is plotted using geogebra online graphing
b) From the table above we can see that Anna makes more stuffing than Jason.
c) Anna has a savings of $100. Hence this can be represented by the points (0, 100) and (250, 10). Using the equation of a line:
We can see from the graph that there is a y intercept at 100. That is the earnings starts from 100.
The equation of a line is given as y = mx + b, where m is the slope and b is the y intercept (initial value)
For the first graph, the slope is 1/20 and the initial value is 0 while for the second graph the slope is 1/15 and the initial value is 100
D) The line pass through (10, 10) and (100, 40), hence:
