In a science experiment, Tania uses 0.8 ounce of water to create a reaction. She wants the next reaction to be 0.1 times the siz

sergij07 [2.7K]

Answer:

0.08 ounce

Step-by-step explanation:

If the size of Tania's reaction is proportional to the amount of water used, then she can reduce the reaction size to 0.1 of its previous value by reducing the quantity of water to 0.1 of its previous value:

0.1 × 0.8 oz = 0.08 oz

The size of Tania's reaction may depend on other factors, so changing the amound of water may have no effect whatever. If water serves as a damper on the reaction, Tania may need to increase the amount of water used.

We do not have enough information to determine an appropriate answer to this question.

Hodel just got her driver's license. Her parents offer her two options. 1. They'll buy her a used car that will cost her $0.50 p

Romashka-Z-Leto [24]

Answer:

The second option will cost her less than the first one.

Step-by-step explanation:

In order to solve this problem we will create two functions to represent the cost of the car in function of the miles drove by her.

For the first option we have:

$cost_1(x) = 0.5*x$

For the second option we have:

$cost_2(x) = 5000 + 0.1*x$

Since she intends to drive it for 10,000 miles per year for 6 years, then the total mileage she intends to drive her car is 60,000 miles. Applying this to the formula of each car and we have:

$cost_1(60000) = 0.5*60000 = 30000$

$cost_2(60000) = 5000 + 60000*0.1 = 11000$

The second option will cost her less than the first one.
