Answer:
25 feet
Step-by-step explanation:
Since there are 3 rectangles, we can simply combine them into one big rectangle. The small rectangle each had a length of 36, we can multiply that by 3 to get the length of our big rectangle. This gives us 108 as our length.
Since perimeter is found by 2*l + 2w, which is equal to 366 in this question, we can setup an equation like this:
2*108 + 2w = 366.
Now we can solve for w.
2w = 150
w = 75.
The width of the big rectangle was calculated as 75. However, the question asked for the width of the small rectangle, so we need to divide this number by 3, giving us 25 feet as our final answer.
The final cost of the tablet is c(t) = 1.08p = 1.08(0.85t) = 0.918t
Required function is c(t) = 0.918t
Answer:
C = 2√(Aπ).
Step-by-step explanation:
The area A = π r^2 where r = radius
and the circumference = 2 π r.
From the formula for the area r = √(A / π)
So the circumference is found by substituting in C = 2 π r for r:
C = 2 π √(A / π)
C = 2√(Aπ).
Answer:
Step-by-step explanation:
Since x=-4 plug in the -4 into the equation to find y,
-5(-4)-4y=16
20-4y=16 -20 -20 __________
-4y=-4
-4y/-4=-4/-4
___________
y=1
So now you found both x and y so plug in both now to check if both are correct.
-5(-4)-4(1)=16
20-4=16
16=16
So both y and x are correct.
Hope this helps!:)
