Answer:
B.
Step-by-step explanation:
So there are 16 grams initally. Then, the amount of water decreases by 3.5%.
So first we must find 3.5% of 16. 3.5% in decimal form is 0.035, since you divide 3.5 by 100. Then, when you multiply 0.035 by 16, you get 0.56. Since the solution decreased by that percentage, you must subtract 0.56 from 16, which is 15.44.
Then the amount of water decreases by 4.25%. That in decimal form is 0.0425. You multiply it by 15.44, and it comes out to 0.6562. You subtract that from 15.44, not 16, since some of the water has evaporated. So you get 14.7838.
4. -5
5. -3
7. 17
8. 5
9. -101
10. 0
11. 16
Everything else you did is correct

Solve for x over the real numbers using factor method:
10 x^2 + 19 x - 15 = 0
The left hand side factors into a product with two terms:
(2 x + 5) (5 x - 3) = 0
Split into two equations:
2 x + 5 = 0 or 5 x - 3 = 0
Subtract 5 from both sides:
2 x = -5 or 5 x - 3 = 0
Divide both sides by 2:
x = -5/2 or 5 x - 3 = 0
Add 3 to both sides:
x = -5/2 or 5 x = 3
Divide both sides by 5:
Answer: x = -5/2 or x = 3/5
Answer:
it is increasing
Step-by-step explanation:
Alright, let's begin! We start with 37.8 and then divide it with..7.6! Now, we try to get the answer of that.
37.8 ÷ 7.6 = 4.973.
However, we need to bring it down to an estimate. It would then be 4.97. Although, we need to also see if our answer is correct.
4.97 × 7.6 = 37.7
There is more answers closer to the number but this should be the correct answer due to it being the answer of all the steps I used.
But wait! We need the round the answer to the nearest whole number. So, it would be 38.
So, overall, it will be 38 cotton swabs tall.
Hope this helps!
