We can say that the area of the figure equals...

5.5 by 9 rectangle - 2 by 2 triangle - 2 by 5 triangle - 9 by 3.5 triangle

5.5 by 9 rectangle = 5.5 x 9 = 49.5 un²

2 by 2 triangle = 1/2 x 2 x 2 = 2 un²

2 by 5 triangle = 1/2 x 2 x 5 = 5 un²

9 by 3.5 triangle = 1/2 x 9 x 3.5 = 15.75 un²

area of figure = 49.5 un² - 2 un² - 5 un² - 15.75 un² = 26.75 un²

answer: 26.75 un²

Bill works for a large food service company. In one hour he can make 19 sandwiches or he can make 40 salads. Bill works 7 hours

wolverine [178]

Answer:

$x=216 salads$

Step-by-step explanation:

One Hour:

Salad=40

Sandwich=19

Total work time $T=7$

Generally

Time to make 30 sandwiches is

$T_s=\frac{30}{19}$

$T-s=1.6hours$

Therefore

Bill has 7-1.6 hours to make salads and can make x about of salads in

$x=(7-1.6)*40$

$x=5.4*40$

$x=216 salads$

Safety by-laws state that for a ladder to be stable, the angle the base of the ladder makes with the ground should be between 70

tatiyna

Cos(angle) = adjacent/hypotenuse

Cos(angle) = 1.5/10

Angle = arccos(1.5/10)

Angle = 81.37 degrees

Although the angle is close, it is over the 80 degrees, so the inspector should be concerned.

Okay so what we know is that there are 6 sides.
—————-————————————————————

3separate groups have the same measurements. So really 3 groups of 2 that have the same measurements.
—————————————————————
2 sides are 3*2 —————>an area of 6
2 sides are 3*2—————>an area of 6
2 sides are 2*2—————>an area of 4
—————————————————————so, we add those #s up and get 6+6+4 which equals 16 as your answer.
