Answer:
The model will be approximately 5 cotton swabs tall.
The model will be 6 toothpicks tall.
Step-by-step explanation:
Find the number of centimeters in the scale model represented by 1 foot on the actual school.
1 ft
1.26 cm
1 foot on the actual school equals 1.26 centimeters on the scale model.
Find the height for your scale model represented by the height of the school.
1 ft × 30
1.26 cm × 30
=
30 ft
37.8 cm
The school will be 37.8 cm tall in your model.
To find how many toothpicks tall your model will be, divide its total height by the height of one toothpick.
37.8 cm ÷ 6.3 cm = 6
The model will be 6 toothpicks tall.
To find how many cotton swabs tall your model will be, divide the height of the model by the height of one cotton swab. If necessary, round to the nearest whole number.
37.8 cm ÷ 7.7 cm ≈ 5
The model will be approximately 5 cotton swabs tall.
ANSWER:
The temperature in Small ville, six hours ago was 13 degrees.
SOLUTION:
Given, current temperature in Smallville is 20 degrees.
And this is 6 degrees less than twice the temperature that it was six hours ago.
We need to find what was the temperature six hours ago.
Let the temperature six hours ago be x.
Then, 2x - 6 = 20 [ according to the given information
2x = 20 + 6
2x = 26
x =
x = 13 degrees.
Temperature six hours ago was 13 degrees
Hence, the temperature in smallville , six hours ago was 13 degrees.
