x+y≤30 and 2.50x+2.75y≥44 are the inequalities that model given situation.
Step-by-step explanation:
Given,
Number of banana breads and nut breads to bake = at most 30
At most 30 means the amount cannot exceed 30.
Selling price of each banana bread = $2.50
Selling price of each nut bread = $2.75
Amount to make = $44 at least
At least 44 means that the amount cannot be less than 44.
Let,
x represent the number of loaves of banana bread to be sold
y represent the number of loaves of nut bread to be sold
x+y≤30
2.50x+2.75y≥44
x+y≤30 and 2.50x+2.75y≥44 are the inequalities that model given situation.

Answer:
<u>The correct answer is that AC = 4x - 2 or 2(2x - 1)</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
AD = 6x + 10
CD = 2x + 12
2. Let's find the length of AC
AC = AD - CD
Replacing with the real values:
AC = (6x + 10) - (2x + 12)
AC = 6x + 10 - 2x - 12
AC = 6x - 2x + 10 - 12
<u>AC = 4x -2 or 2(2x - 1)</u>
Answer:
80 hours is needed
Step-by-step explanation:
answer is d
There are a lot of information's that are already given in the question. Based on these information's the answer can be deduced.
1 mile = 1609 meters
Then
70 miles = 1609 * 70 meters
= 112630 meters
again
1 hour = 3600 seconds
3 hours = 3600 * 3 seconds
= 10800 seconds
So
Speed = 112630/10800 meters/second
= 10.4 meters per second.
So the falcon was flying at a speed of 10.4 meters per second.
Answer:
76 m

Step-by-step explanation:
First of all, we know all of the sides already except for two, so we need to find them. (The side on the very left and top).
The side on the very top is 18 since the top and bottom are the same lengths. This also implies to the side on the very left. The sides (4+4+4) is equivalent to the side we are trying to find. We now know it is 12.
Second, to find the perimeter of almost every shape, we add all of the sides together.
18+4+8+4+8+4+18+12
This gives the answer of 76 m. (don't forget the label!)
