IrinaVladis [17]

Answer:

Step-by-step explanation:

<u>Given:</u>

There were 120 people in total.

60% were parents.

<u>To find:</u>

Number of parents attended.

Solution:

1. 60% of 120

It can also be written as:

\frac{60}{100}\times \frac{120}{1}

Simplify

  • Cancel zeros

\frac{60}{100}\\\\=\frac{6}{10}

  • Divide by common factor (2)

\frac{6\div2}{10\div2}=\frac{3}{5}

2. \bold{\frac{3}{5}\times \frac{120}{1}}

Multiply

\frac{3\times120}{5\times1} = \frac{360}{5}

Divide

\frac{360}{5}= 360\div5=72

Therefore, 72 parents attended the game.

Estimate the solution to the equation 3.1g = 20.9 to the nearest whole number. about 7 about 8 about 10 about 5
lubasha [3.4K]
Divide both sides by 3.1 and find g = 20.9/3.1 ≈ 6.7 ≈ 7.
You can estimate this without a calculator by saying 20.9 ≈ 21 and 3.1≈3, then 21/3=7.

In general, be careful with rounding before a calculation, because the rounding errors can be enlarged, messing up the accuracy of your answer. It's best to round only at the end.

Help me please I beg.
Nastasia [14]

Answer:

B

Step-by-step explanation:

2√12 = √4 x 3 = 4√3 = (4√3 x 3√5)

            √36 = 6 = (6 x √30)

4√3 x 3√5 = 12√15

6 x √30 =  6√30

12√15  x √30      180√2

÷                      =

6√30 x √30       180

-----------

180√2

÷

180

------------

= √2 or 1.41

I hope this helps!
