Scott bought a 5lb bag of cookies at the bakery. He ate 2/5 of the bag and his sister ate 2/9 of the bag. What fraction of the b
satela [25.4K]

Answer:  Fraction they both eat = \dfrac{28}{45}.

Fraction of bag remains =  \dfrac{17}{45}

Step-by-step explanation:

Given: Part of cookies eaten by  Scott = \dfrac25

Part of cookies eaten by sister = \dfrac{2}{9}

Fraction they both eat = \dfrac25+\dfrac29=\dfrac{9\times2+5\times2}{5\times9}

=\dfrac{18+10}{45}\\\\=\dfrac{28}{45}

Fraction of the bag remain = 1-\dfrac{28}{45}=\dfrac{45-28}{45}=\dfrac{17}{45}

[Taking fraction of whole bag =1]

Hence, Fraction they both eat = \dfrac{28}{45}.

Fraction of bag remains =  \dfrac{17}{45}

The quadratic function below has an axis of symmetry through x = -4; a vertex at (-4, -9) and zeroes at x = -7 and x = 0.
Pavlova-9 [17]

Answer:

True

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (- 4, - 9), thus

y = a(x + 4)² - 9

To find a substitute the coordinates of the zero (- 7, 0) into the equation.

0 = a(- 7 + 4)² - 9, that is

0 = 9a - 9 ( add 9 to both sides )

9a = 9 ( divide both sides by 9 )

a = 1, thus

y = (x + 4)² - 9 ← expand factor using FOIL

y = x² + 8x + 16 - 9

y = x² + 8x + 7

mars1129 [50]

Answer:

Proportion of games an NFL team wins.

Proportion of defective products in a shipment.

Proportion of voters of a certain candidate in an election.

Step-by-step explanation:

Proportion is a relationship between measures.

Examples in real life are:

Proportion of games an NFL team wins.

For example, this past regular season, the Buffalo Bills won 13 games out of 16, so the proportion of games won by the Bills is 13/16 = 0.8125.

Other possible examples are:

Proportion of defective products in a shipment.

Proportion of voters of a certain candidate in an election.
