Answer:

T4 = -2°F

Step-by-step explanation:

Given the following data;

Current temperature = 10°F

Constant, K = 3°F

Time, t = 4 hours

In four (4) hours, we have;

T = kt

Substituting into the equation, we have;

T = 3 * 4

T = 12°F

T4 = current temp - new temp

T4 = 10°F - 12°F

T4 = -2°F

Therefore, the temperature it will be in 4 hours is - 2°F.

The People's Paper total cost:

145w

Number of weeks ad should run For cost at daily info to be less expensive than peoples choice';

Daily Info total cost < people's choice

650 + 80w < 145w

650/65 < 65w / 65

10 < w

w > 10

Marat has $16 to buy doughnuts for Saturday morning breakfast. Specialty doughnuts cost $2 each and glazed doughnuts cost $1 eac
Mademuasel [1]

Answer:

<h2>Two possibilities are 8 Specialty doughnuts or, 16 glazed doughnuts.</h2>

Step-by-step explanation:

Let, Marat can buy x specialty doughnuts and y glazed doughnuts.

Marat will be able to buy the doughnuts if 2x + y \leq 16.

If we put x = 0 in 2x + y = 16, then y = 16.

For y = 0, x = 8.

Marat can buy 0 doughnuts or can buy some, but the total amount needs to be in between 16.
