<em>Tony rounded each of the numbers 1,143 and 1,149 to the nearest hundred. Which choice correctly compares the rounded numbers? </em>
<em></em>
Answer:
Step-by-step explanation:
Given
1,143 and 1,149
Required
Which of the option is correct
We start by approximating both numbers to nearest digit
<em>1,143; when approximated to nearest hundred is 1,100</em>
<em>1,149; when approximated to nearest hundred is also 1,100</em>
Hence;
1,143 ≅ 1,100
1,149 ≅ 1,100
Comparing both results, we have that
From the list of given options, option C is correct;
Answer:
C
Step-by-step explanation:
Given
A =
Substitute the given values with h = a, then
16.5 = ( multiply both sides by 2 )
33 = a(a + 8) ← distribute
33 = a² + 8a ( subtract 33 from both sides )
0 = a² + 8a - 33 ← in standard form
0 = (a + 11)(a - 3) ← in factored form
Equate each factor to zero and solve for a
a + 11 = 0 ⇒ a = - 11
a - 3 = 0 ⇒ a = 3
However, a > 0 thus a = 3
Hence the height is 3 feet
