It is already in standard form.
Answer:
Step-by-step explanation:
It is simply the sumation of a triangle and a rectangle minus a half circle.
area triangle + area rectangle - area half circle = Total area
1/2( bh ) + bh - (π (d/2)²) / 2 = Total area
0.5(7)(6) + (10)(7) - (π (7/2)² ) / 2 = Total area cm²
21 + 70 - 19.24 = 71.76 cm²
Answer:
45 days
Step-by-step explanation:
first Project using 45 workers, is finished in 15 days.
that is 15(45) = 675 worker•days of labor
second project is expected to take 675 worker•days of labor to complete as well
675 worker•days/ 15 workers = 45 days
Answer:
9y+1=32y+1+54
collect like terms, a symbol changes once it crosses the equal to sign =
9y-32y=1+54-1
-23y=54
divide both sides by -23
-23y/-23=54/-23
-23 will cancel -23 to give y
y=54/-23
y=-2.4 or 2 whole number 8/23
