Answer:

(a) cannot be determined

(b) 44 cm^2

(d) 180 m^2

(e) 132 m^2

Step-by-step explanation:

(a) missing a horizontal dimension

(b) The difference between the bounding rectangle and the lower-left cutout is ...

(8 cm)(7 cm) -(3 cm)(4 cm) = (56 -12) cm^2 = 44 cm^2

(13 m)(7 m) -(4 m)(1 m) = (91 -4) m^2 = 87 m^2

(d) The difference between the bounding rectangle and the two cutouts is ...

(20 m)(25 m) -(16 m)(20 m) = (20 m)(25 -16) m = (20 m)(9 m) = 180 m^2

(e) The difference between the bounding rectangle and the two cutouts is ...

(14 m)(12 m) -(12 m)(3 m) = (12 m)(14 -3) m = (12 m)(11 m) = 132 m^2

Naomi is a songwriter who collects royalties on her songs whenever they are played in

barxatty [35]

Equations can be solved in several ways; one of these ways is the graphical method.

The number of commercials, x, and the number of movies, y, on which Naomi's songs were played are 5 and 2, respectively.

Let:

$x \to$ commercials

$y \to$ movies

She earned a total of $300.

This is represented as:

$20x + 100y =300$

Her songs were played on 3 more commercials than movies.

This is represented as:

$x = 3 + y$

See attachment for the graphs of

$20x + 100y =300$

$x = 3 + y$

From the graph, the lines of both equations intersect at:

$x = 5$

$y = 2$

This means that:

The number of movies is 2
The number of commercials is 5

Simplify the expression -7/9 - 5/10

sattari [20]

We can sum two fractions if they have the same denominator, so we have to rewrite both fractions so that they'll have the same denominator.

We can generate equivalent fractions by multiplying both numerator and denominator by the same number.

So, we have

$-\dfrac{7}{9} = -\dfrac{7\cdot 10}{9\cdot 10} = -\dfrac{70}{90}$

Similarly, we have

$-\dfrac{5}{10} = -\dfrac{5\cdot 9}{10\cdot 9} = -\dfrac{45}{90}$

Now we can sum the fractions:

$-\dfrac{7}{9}-\dfrac{5}{10} = -\dfrac{70}{90}-\dfrac{45}{90} = \dfrac{-70-45}{90} = -\dfrac{115}{90} = -\dfrac{23}{18}$
