This simplifies to 8 - 4 + 2/2 which can be
8 - 4 + 1 = 8 - 3, so the simplest form is 8 - 3.
I can't write the symbol, but it would be X<30 and the <would have a horizontal line under it so that it would mean x is less than or equal to 30
No, they're not equivalent
Answer:
the company must buy 22 gallons to paint this entire area
Step-by-step explanation:
The circumference of the tank is given and is C = 2(pi)r, where r is the area.
118 ft
Here the circumference is C = 2(pi)(r) = 118 ft, which leads to r = ------------ ≈
18.79 ft ≈ r 2(pi)
The area of the sides is A = (circumference)(height), or approximately
(118 ft)(50 ft) = 5900 ft², and the area of the top is A = πr², which here comes to (π)(18.79 ft)² ≈ 1109 ft². Combining these two sub-areas, we get:
A(total) = 1109 ft² + 5900 ft² ≈ 7009 ft²
To determine how many gallons of paint will be needed to paint only the top and sides, we divide 7009 ft² by the coverage rate, which is
320 ft²
-----------
1 gallon
which results in:
7009 ft²
---------------------- ≈ 21.9 gallons
320 ft² / gallon
Since the paint comes only in full gallon cans, the company must buy 22 gallons to paint this entire area.
F(x) = 2x + 4
f(x-5) shifts (fx) five units to the right, then
f(x-5) = 2(x-5) + 4 = 2x - k
2x - 10 + 4 = 2x - k
k = 6
