Answer: At noon the temperature outside of Hector's home was 4 degree warmer than the temperature outside of gale's home.
Step-by-step explanation:
Here, x represents the number of hours after noon while g(x) and f(x) represents the temperature of gale's and hector's home respectively in x hours.
Since, at noon, x = 0
And, by the table g(x=0) = -1
That is, the temperature of gale's home is -1° F at noon.
And, by the given graph, f(x=0) = 3
That is, the the temperature of hector's home is 3° F at noon.
And, f(0)-g(0) = 3-(-1) = 4°F
That is, the difference between the temperature of hector's home at noon and the temperature of gale's home at noon is 4°F.
The equations and numbers you apply in math, will come in handy because in the future you may encounter problems like you faced in your math problems, so real numbers are very helpful.
Answer:
D) 70 m²
Step-by-step explanation:
1. Find the base and height:
Since, for each grid, the side length is 2 meters, we multiply the lengths by 2 meters: <em>9 - 2 = 7 -> 7*2 m = 14 m</em>; <em>7 - 2 = 5 -> 5*2 m = 10 m</em>
2. Find the area:
Use the equation: 1/2*b*h ->
1/2 * 14 m * 10 m = 140/2 m² = 70 m².
