I think the equation is written as 3r + 2.5p, where r is the number of roses and p is the number of petunias. To find the total cost, substitute 777 to r and 888 to p. The total cost would then be:
Total Cost = 3r + 2.5p
Total Cost = 3(777) + 2.5(888)
Total Cost = 4551
The total cost would be $4,551.
40 divided by 8 is equal to 5 so 5 is going to be the zoom size
C) 16 bc if you think about it like 25% chance you going to pull the same chip out without looking
<span>These are 6 questions (from a to f). Each has its complete answer.

</span><span>a. Calculate the area of the floor of the tent using area formulas for rectangles and triangles.
</span><span>
</span>
1) The trapezoid is composed of two congruent triangles and one rectangle.
2) The area of each triangle is: (1/2)bh
3) The base of each triangle is half the difference of the two bases: (28 - 10) / 2 ft
4) The height of each triangle is the separation between the two bases: 12 ft
5) The area of the rectangle is base × height = base × separation between the bases.
6) Calculation of the area of the floor of the tent: two congruent triangles + rectangle
2 × (1/2) × (28 - 10) /2 × 12 + 10 × 12 = 228 ft²
<span /><span /><span>
b. Calculate the area of the floor using the formula for a trapezoid.
</span>
formula: area of trapezoid = distance between the bases ₓ (base₁ + base₂)/2
12 × (28 + 10) / 2 = 228 ft²
<span /><span /><span>
c. What did you discover about the two methods of calculating the area of the floor?
</span>
The two methods are equivalent, as they are just two ways of calculating the areas by spliting the figure in different ways.
<span /><span /><span>
d. Find the perimeter of the tent and the perimeter of a sleeping bag.
</span>
The perimeter is the length of all the sides.
Perimeter of the tent: 10ft + 15ft + 28ft + 15ft = 68 ft
Perimeter of each sleeping bag: 6.7 ft + 2.3 ft = 9 ft
<span /><span /><span>
e. How much area do you need for one sleeping bag?
</span>
area = 6.7 ft × 2.3 ft = 15.41 ft²
<span /><span /><span>
f. Based on total area alone (ignore odd angles), how many people will be able to sleep in this tent? Explain.
</span>
You have to divide the area of the floor by the area of one sleeping bag to calculate how many sleeping bags fit in the floor:
⇒ 228 ft² / 15.41 ft² = 14.8
Therefore, 14 people can sleep in the tent.
