1 gal = 4 quarts
3 gal = 4 * 3 = 12 quarts
12 / 2 = 6 pitchers
Answer:
im pretty sure the last one
Step-by-step explanation:
Given:
The polygon in the given figure are similar.
To find:
The missing side length.
Solution:
We know that the corresponding sides of similar figures are proportional.
The given polygons are similar, so the their corresponding sides are proportional.
So, the missing values in the equation of proportion are 15, 40, 32 respectively.
On solving the above equation, we get
Therefore, the value of x is 12.
Part (a):
We have length of fence is l (side parallel to the house) and width of fence (side perpendicular to the house) is w.
We are given that:
The total fencing is 60 ft. This means that the perimeter of the yard is 60 feet. Note that the perimeter of the yard would be l + 2w not 2l + 2w. This is because on of the length is eliminated as this length is already occupied by the house. This means that:
l + 2w = 60
We are also given that:
Area of yard is 400 ft². This means that:
lw = 400
Based on the above, the system of equations describing the situation would be:
l + 2w = 60 .............> equation I
lw = 400 ...............> equation II
Part (b):
We want to get the length and width. This means that we will solve the system of equations in part a.
In equation I, we have:
l + 2w = 60
This equation can be rewritten as:
l = 60 - 2w ............> equation III
Substitute with equation III in equation II and solve for w as follows:
lw = 400
(60-2w)(w) = 400
60w - 2w² = 400
2w² - 60w + 400 = 0
(w-20)(w-10) = 0
either w-20 = 0 ...........> w = 20 ft
or w-10 = 0 ............> w = 10 ft
Now, we will substitute with the value of w in equation III to get l as follows:
at w = 20:
l = 60 - 2w = 60 - 2(20) = 60 - 40 = 20 ft
at w = 10:
l = 60 - 2w = 60 - 2(10) = 60 - 20 = 40 ft
Based on the above, we have two possibilities for the dimensions:
either length is 20 ft and width is 20 ft
or length is 40 ft and width is 10 ft
Hope this helps :)
