A student read 3 000 146 as "three thousand one hundred forty-six." how do you explain the students error
Mumz [18]
The digit 3 is in the millions place value, hence it is worth three million, not three thousand.
Therefore, 3,000,146 should be read as three million, one hundred and forty-six, and NOT three thousand, one hundred and forty-six.
Hope this answer helps you! If it did, please mark it as the brainiest! I would really appreciate it! :)

Equation using the quadratic fromula for 0.05x^2 + 1.1x = 250
Anuta_ua [19.1K]

Answer:

x=60.56, x=-82.56

Step-by-step explanation:

Solve using quadratic formula

Formula is

x=\frac{-b+-\sqrt{b^2-4ac}}{2a}

0.05x^2 + 1.1x = 250

Subtract 250 on both sides

0.05x^2 + 1.1x - 250=0

a= 0.05, b=1.1 , c=-250

Plug in the values in the formula

x=\frac{-1.1+-\sqrt{(1.1)^2-4(0.05)(-250)}}{2(0.05)}

x=\frac{-1.1+-7.156116265}{0.1}

Now make two equations , one with +  and one with -

then we solve for x

x=\frac{-1.1+7.156116265}{0.1}

x=60.56

x=\frac{-1.1-7.156116265}{0.1}

x=-82.56
