Step-by-step explanation:
Answer:
(-2, 1).
Step-by-step explanation:
The x coordinates are -1 and -3 and the y coordinates are 4 and -2.
So the midpoint is (-1 + -3)/2, ( 4 + -2) / 2
= (-4/2, 2/2)
= (-2, 1).
Answer: The toy should be 2.4 inches tall
------------------------------------
------------------------------------
Explanation:
First convert 6 ft to inches
6 ft = (6 ft)*(12 in/1 ft) = (6*12) inches = 72 inches
So, 6 ft = 72 inches
The toy is manufactured with a scale of 1:30 meaning that the toy is 1 unit tall compared to the soldier which is 30 units tall. The soldier is 30 times taller than the toy. We can therefore form the ratio
1/30 = x/72
where x is the height of the toy soldier in inches
Cross multiply and solve for x
1/30 = x/72
1*72 = 30*x
72 = 30*x
72/30 = 30*x/30
72/30 = x
x = 72/30
x = 12/5
x = 2.4
So the toy should be 2.4 inches tall.
Note how 30 times 2.4 gives us
30*2.4 = 72
which fits with the theme that the real soldier is 30 times taller than the toy counter part.
