A school will have a fall festival if at least 40% of the 500 students plan to attend. How many students must agree to attend in
artcher [175]

Answer:

200 students must agree to attend in order for the school to have the festival.

Step-by-step explanation:

200 is 40% of 500. We can also use fractions to figure this out.

\frac{40}{100} =\frac{x}{500}

For 100 to become 500 it must be multiplied by 5. And whatever we do to the denominator we have to do to the numerator. So we multiply 40 × 5 = <em>x</em>

<em>x</em> = 200

\frac{40*5}{100*5} = \frac{x}{500}      

\frac{40}{100} =\frac{200}{500}

Geometry: The rectangle shown has a perimeter of 34cm and the given area. Its length is 5 more than twice it's width. Write and
Thepotemich [5.8K]

w - width

2w + 5 - length

w + w + (2w + 5) + (2w + 5) = 6w + 10 - perimeter

34 cm - perimeter

The equation:

6w + 10 = 34    <em>subtract 10 from both sides</em>

6w = 24    <em>divide both sides by 6</em>

w = 4 cm

2w + 5 = 2(4) + 5 = 8 + 5 = 13 cm

<h3>Answer: Width = 4cm, Length = 13cm</h3>
