Hi!
So, it looks like you're doing ratios.
Let's look at 9). If the model car is 4 inches long, and 1 inch equals 4 feet, than the actual car is 16 feet long. We know this because 4x4=16.
11) is also just as simple. If 1 cm is 11 km, and the two cities are 99 km apart, then on the map they are 9 cm apart. 11x9 is 99.
13) This is a 1:2 ratio. Basically, the flagpole's shadow is half of its height. You half the man's height to get a 3 foot shadow.
And, finally, 15)- if the model is 4 inches to the real life train's 3 feet, the actual train is 120 ft long, given that the model is 40 in long. 40x3=120.
I hope this helps! :)
Answer:
no
Step-by-step explanation: does not pass the vertical line test
Cos 57 it has to add up to 90
Answer:
m = 4.5
Step-by-step explanation:
m is the variable for slope (just for validation)
y = 25 + 4.5 (x - 5)
Expand,
y = 25 + 4.5x - 22.5
Collect like terms,
y = 4.5x + 2.5
The slope of the gradient is always the coefficient of x
Therefore, m = 4.5
Hope this helped!! :)
To find the solution, simply take 3 and divide it by 12. 3/12 as a fraction would be simplified down to 1/4 or 0.25. Therefore, each student would receive one quarter of a pizza.
