If you divide what she spent (2.65) buy the price per ounce (0.25) , you should come up with 10.6 ounces, which is the amount she bought.
Hope this helps :)
Distributive property is used when you have a number outside a set of numbers in parenthesis.
Using the distributive property, you multiply the number outside the parenthesis by each number inside the parenthesis.
The first answer is correct because they are multiplying 9 by 20 and adding it to 9 multiplied by 6.
Answer:
4
Step-by-step explanation:
Every year, the world grows by 1.1%. Converting to a decimal, we can divide by 100 to get 1.1% = 0.011. This means that the world grows by 0.011 exponentially each year. To put this into an expression, we can add 1 to our percentage to get 1.011. This represents 1 = 100% (the original population) and the growth of 1.1% = 0.011. We multiply the rate including the growth by the population to get the population after one year. After the first year, we have
population * 1.011 as the new population after one year. We do that for every year, so the second year's population is population*(1.011)*(1.011) and so on. If x represents the amount of years, then the population can be represented as
(original population)*1.011ˣ
Therefore, to get from 7 billion to 7.31 billion, we have
7 billion * 1.011ˣ = 7.31 billion
divide both sides by 7 billion to relatively isolate the x
1.011ˣ = 7.31/7
Another way of writing this is
log (base 1.011) (7.31/7) = x
≈ 3.96
Rounding to the nearest whole number, we get 4 as our answer
Answer:
A. is the correct one. The statement makes sense.
Step-by-step explanation:
A. This is true because if you make your graph starting from the lowest value then the graph will use more space to fit the data and it will make it look bigger. Also, the variation will seem higher because it will feel that you are increasing it from 0, so the relative increase will be higher.
B. Reducing the range of the vertical axis will increase the relative size of variation, not make it decrease, as we explained in A.
C. Even though it is technically certain that the data shown is the same as before, the way to show data also matters. And by making changes on the presentation of your data you can obtain different results on the impression that leaves to people.
D. This is just false, because you are indeed dereasing the range of the vertical axis, not increasing it.
I believe it's 15, but correct me if I'm wrong
This is because there is one 10 in 15. This gives you 3 tens and 5 in the ones.
