Answer:
300,000.
Step-by-step explanation:
6x10^-3 / 2x10^-8
= 3 x (10^(-3- (-8))
= 3 x 10^5
= 300,000
Answer: A and B
Step-by-step explanation:
I think that the answer is A and B because in this case, R is clearly a negative number, because it’s below 0. So if we change the symbol in front of the R, it has to be positive. Let’s say R is -20. Negative R should be - - 20, which is + 20. So -R > 0. We and also say that -R = V because there are an equal number of bounds that separate R and V from 0, and since -R is the inverse of R, it has to be equal to V.
To solve this, you need to subtract 180 from 400: (400-180=220). After that (I used the fraction/proportion/variable way, but there are others), so 220/400=%(p)/100. Multiply diaganolly, so 400*p=400p, which is equal to 220*100=22000. Therefore, 400p=22000. Now, you have to isolate the variable by dividing both sides by 400: 400p/400=p, and 22000/400=55. Therefore, p=55, or %=55, so the answer is 55%, or C.
Answer:
4650 adults
Step-by-step explanation:
The ratio of people who drink coffee to total people is 31/50, or 0.62
To find the number of adults in the town who drink coffee, multiply the ratio by how many people there are in the town.
Plugging in the values we are given,
0.62 * 7500 = 4650
We can expect 4650 adults to drink coffee in the town.
Answer:
x and y can both equal 1
Step-by-step explanation:
Since we have:
And we know that they equal each other, 1 should be the best answer.
1¹ = 1¹
1 = 1
