Must be put in groups of 14 square units or 16 square units triangle EFG
Genrish500 [490]

Answer:

Area 14 = PQRS + UVW; Area 16 = ABCD + EFG

Step-by-step explanation:

PQRS:  A = lw     = 7 × 2        = 14

ABCD: A = lw     = 4 × 4        = 16

UVW:  A  = ½bh = ½ × 7 × 4 = 14

EFG:    A = ½bh = ½ × 8 × 4 = 16

Area 14 = PQRS + UVW

Area 16 = ABCD + EFG

Pls help me i just need help
Ray Of Light [21]

Step-by-step explanation:

the total cost is, of course, first the cost to buy the copier, and then the running costs per copy made.

it is really that easy.

the equations just put this into mathematical form :

A

y = 0.02×x + 800

B

y = 0.06×x + 600

please notice, we put $600 or $800 in as constant term, because these costs are the starting costs that we have, even if we never make a single copy (x = 0).

and then the total cost goes up with every copy we make.

I cannot draw here.

so, to find the number of copies where both copier systems would cost the same, means we have to say both equating deliver the same result :

0.02×x + 800 = 0.06×x + 600

200 = 0.04×x

x = 200 / 0.04 = 5000

when making 5000 copies both costs are the same.
