STEP 1:
You need to find the area of the circular pad.
Circle Area= πr^2
we need the radius which is half of the diameter given
=π(50÷2)^2
=(3.14)(25)^2
=(3.14)(625)
=1,963.495 ft^2 total area
STEP 2:
Find how much paint is needed by dividing a can's coverage into what's needed.
=1963.495 ÷ 200
=9.817
=10 cans are needed (because you cannot buy a part of a can, you need to round up)
ANSWER: 10 cans are needed
Hope this helps! :)
mj thinks of a number. she adds 2 to the number then multiples the result by 3. The answer is the same as adding 5 to the number them multiplying by 2
my number is d
3 (d×2) = 2 (d+5)
3×d + 3×2 = 2×d + 2×5
3d + 6 = 2d + 10
3d +6 -6 -2d = 2d - 10 - 6
3d - 2d = 10 - 6
d = 4

Step-by-step explanation:
tried substitution and elimination method but got different answers to I graphed these equations and found the point of intersection
5/3x + 25/8y = 31.25
29/12x + 9/16y = 15.15
point of intersection (4.5, 7.6)
Answer:
-12
Step-by-step explanation:
Use synthetic division to find the remainder:
a + 2 yields the synthetic division divisor -2. The four coefficients of a^3 - 4 are {1, 0, 0, -4}. Setting up synthetic division results in:
-2 / 1 0 0 -4
-2 4 -8
-------------------------
1 -2 4 -12
The remainder is -12. This is also the value of a^3 - 4 when a = -2.
