If kubby has only 300g of minced beef, he should use 600g chopped tomatoes, 450ml stock, and 225ml red wine.
Reason:
300g of 400g is a 25% decrease, so all other ingredients must be multiplied by .75 to even the distribution.
Answer: 62+63+64
Step-by-step explanation:
Divide 189 by 2. That gives you 63. Then go for a number 1 above it and 1 below it.
Step 1: Group this into two groups:

When you do that, be sure to group the "–" into the group with the 9 and make sure there's "+" between the groups.
Step 2: Factor out the GCF from both individual groups:

Step 3: Notice both groups have that (h+2)? That's a new GCF between the two groups, so factor that out:

Step 4: That
piece can be factored further, since it's a difference of squares:

Now it's factored.

Step-by-step explanation:
<u>Function Modeling</u>
The problem gives us the following conditions: The bottom of Ignacio's desktop is 74.5 cm from the floor, and the top of his legs is 49.3 cm from the floor. We know the chair where he's sitting at has a knob that raises the legs 4.8 cm per clockwise rotation r. This means that the total distance the legs are raised for r rotations is
. The total distance of his legs from the floor is then:

This distance cannot reach or exceed 74.5 cm, thus

Solving for r

Or, equivalently
