Answer:
Surface Area = 282.6 cm²
Step-by-step explanation:
Formula: SA = 2
rh + 2
r²
SA = 2
rh + 2
r²
SA = 2(3.14)(5)(4) + 2(3.14)(5)
SA = 2(3.14)(5)(4) + 2(3.14)(25)
SA = 125.6 + 157
SA = 282.6 cm²
C because it is icoceles.
Answer:
the statement shows the inverse property of addition as the sum of a number and its inverse is zero.
Step-by-step explanation:
As we know that Inverse Property of Addition states if you add any number to its opposite, the result will be zero.
For example, 13 + (-13) = 0 shows that -13 is the additive inverse of 13.
In other words, the sum of a number and its inverse is zero.
Now checking from the available options,





Thus,

Therefore,
the statement shows the inverse property of addition as the sum of a number and its inverse is zero.
Answer:
x = 8
Step-by-step explanation:
0.4x - 1.2 = 0.15x + 0.8
0.4x - 1.2 + 1.2 = 0.4x
0.15x + 0.8 + 1.2 = 0.15x + 2
0.4x = 0.15x + 2
0.4x - 0.15x = 0.25x
0.15x + 2 - 0.15x = 2
0.25x = 2
0.25x / 0.25 = x
2 / 0.25 = 8
x = 8
