Answer:
3.1 miles
Step-by-step explanation:
2.5 + 4.4 = 6.9
10 - 6.9 = 3.1
to find a slope you subtract the y value of the 2nd point from the y value of the 1st point then you devide that by the difference of the x value of the 2nd point subtracted from the x value of the 1st point. so 5-3 devided by -3-4, 5-3=2, -3-4=-7. so m = 2/-7 is your slope. the slope is usually represented with the letter m.
- The area of Kayla's dollhouse upstairs = 15.15 square feet
- The area of Kayla's dollhouse downstairs = 6.45 square feet
- To find the estimated Total area of Kayla's dollhouse, we would apply the Addition Operation
- The estimated total area is calculated using the formula :
Area of the dollhouse upstairs + Area of the dollhouse downstairs
Rounding to the decimals to the nearest tenth
- The area of Kayla's dollhouse upstairs to the nearest tenth = 15.2 square feet
- The area of Kayla's dollhouse downstairs to the nearest tenth = 6.5 square feet
15.2 square feet + 6.5 square feet = 21.7 square feet
The estimated total area of Kayla's dollhouse is 21.7 square feet

Answer: Jan now has 27 model airplanes.
Step-by-step explanation: The starting figure is 25 model airplanes and this year she has 32% more than she started with. We shall first find out how many that turned out to be. Let the current number of model airplanes be X.
X = 25 + 32%
[To calculate 32% of 25
25 x 32/100
(25 x 32)/100
800/100
8]
X = 25 + 8
X = 33
Now she has 33 model airplanes and she gave out 6 of these to her brother, then she finally has left with her, 33 minus 6 which equals 27.
Jan now has 27 model airplanes left
