How does drawing a rectangle support the idea of composing a larger unit from smaller units

pav-90 [236]

Answer:

When you think rectangles, you think areas. Small areas aggregate to form bigger ones.

If you drew a rectangle, it's easy to divide it into smaller units by simply taking a line through its midsection from one length to the other and one width to the other. One can either form smaller squares or rectangles from a larger one.

When that is one, you'd have taken the larger area of a rectangle which is simply the product of the value of its length and it's the breadth, and divided it into smaller units.

Cheers!

According to the Bureau of Labor Statistics, students who have an after-school job spend an average of 42 fewer minutes per day

IgorLugansk [536]

Answer:

126 hrs

Step-by-step explanation:

-Given the school year has 180 days and the non-working student spends 42 minutes more than the working student.

-The total time during the school year is calculated as;

$Total Time=Time/day \times No \ of \ Days\\\\=42\ minutes \times 180\\\\=7560\ minutes$

We convert our calculated time in hour(1hr=60 minutes):

$=\frac{7560\ mins}{60\ mins}\\\\=126\ hrs$

Hence, the average non-working spends an average of 126 hrs that the working student.

Hey guys please help!!

Advocard [28]

Answer:

Yes

Step-by-step explanation:

g(x) = - $\frac{1}{4}$ x + $\frac{1}{4}$

y = - $\frac{1}{4}$ x + $\frac{1}{4}$ ....... (1)

(1) × 4

4y = - x + 1

x = - 4y + 1

y = - 4x + 1

f(x) = - 4x + 1

∴ f(x) and g(x) are inverses
