At t=1 minute, the reading will be 40.00 °F.

_____
Every half-minute, the temperature difference from the 30 °F air temperature is divided by 2. After 1 minute, the initial 70-30=40 degree difference will be divided by 4. The thermometer will read 30° +40°/4 = 40°

If a hexagon is worth 5 and a triangle is worth 3, what is a circle
Olegator [25]

Answer:

6

Step-by-step explanation:

Call pentagon p, circle c and triangle t

We have 2c + 2p = 2p + 2t + c

p = 5, t = 3 so

2c + 2(5) = 2(5) + 2(3) + c

2c + 10 = 10 + 6 + c

2c = 6 + c

c = 6

Please answer! I’m desperate lol
8_murik_8 [283]

Step-by-step explanation:

A) The bus rental would be the total cost or "C". So 700=250+3m.

B) Solve with properties of equality:

  700 - 250 = 250 + 3m - 250

  450 = 3m

  450/3 = 3m/3

  150 = m

  150 miles

C) Check your answer by plugging the answer into the original equation:

  C = 250 + 3(150)

  C = 250 + 450

  C = 700
