Answer: 60 cm.
Step-by-step explanation:
We can use a ratio table to solve this. We know that 0.6 cm is the same as 3 meters. Yet, how many cm represent 300 meters? So far, we can set up over ratio table like this.
CM: 0.6, ?
M: 3, 300
What did we have to multiply to 3 to get to 300? 100. What we do to one area of the ratio table, we must do the same to the other. We have to multiply 0.6 by 100.
0.6 x 100 = 60
His model has to be 60 cm tall.
The answer is 8.6 units.
To solve this problem you use the distance formula.
What equation describes this variation?
z = kxy
What is the constant of variation?
k = 5
When x = 1 and y = –2, z =
-10
Step by Step Explanation:
With the equation z = kxy and the values for z, x, and y, we can find k.
z = kxy
-75 = (k) (3) (-5)
-75 = (k) (-15)
5 = k
k = 5 (final answer).
To check our work, we just enter all of the values and make sure it adds up.
z = kxy
-75 = (5)(3)(-5)
-75 = 15(-5)
-75 = -75
correct!
Do the same to find the answer for the next part to get -10.
