vagabundo [1.1K]

First, minus salary
paycheck=comission+salary
paychec-salary=comision
6500-1000=5500

comission/sales=5500/45000=0.122222222/1
pecent means parts ou fo 100
x%=x/100
0.122222/1 times 100/100=12.2222/100=12.222%

raketka [301]

M+g≤40
12m+14g=x where x is his total earnings for the week
12m+12g+2g=x, so x-2g=12(m+g) and x-2g≤480. Or x≤480+2g. His earnings cannot exceed 480+2g.

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to

chubhunter [2.5K]

Answer:

Area = 74.1 square units

Step-by-step explanation:

Area of the composite figure = Area of the rectangle + Area of the semicircle

Area o the rectangle = Length × Width

= 10 × 6

= 60 square units

Area of the semicircle = $\frac{1}{2}\pi r^{2}$

Here, r = radius of the semicircle

For the semicircle with radius = $\frac{6}{2}$ = 3 units

Area = $\frac{1}{2}\pi (3)^{2}$

= 4.5π

= 14.14 units²

Total area of the composite figure = 60 + 14.14

= 74.14 square units ≈ 74.1 square units

a bicycle wheel has a diameter of 40 cm how many revolutions would a wheel make if the bike travels 1 km pi=3.14 (answer please

andriy [413]

Circumference of a circle = Diameter × pi
Circumference of a circle = 40 cm × 3.14
Circumference of the wheel = 125.6 cm

1 Km = 1000m
Circumference of the wheel × 1000m = The number of revolutions
125.6 × 1000m = 125600

The wheel would make 125600 revolutions if the bike travels 1 km.
