The weight of an object on the moon is
Tanzania [10]

Answer:

40 2/5Ibs or 40\frac{2}{5} lbs

Step-by-step explanation:

Let weight of object on the moon be represented = Wm

weight of object on the Earth = We

In the above question, we are told:

The weight of an object on the moon is

5 of its weight on Earth.

Hence, mathematically, this is represented as:

 5Wm = We

If a moon rock weighs 202 lbs on Earth

5Wm = 202lbs

Wm = 202lbs/5

Wm = 40\frac{2}{5}Ibs

Therefore, the moon rock weighs 40\frac{2}{5}Ibs on the moon.

AB ← → is tangent to circle O at point A. If m∠AOB = 55°, what is m∠ABO ?
AlladinOne [14]
A tangent forms a right angle with the centre of circle at the point it touches the circumference. i.e. OAB = 90 degrees
If AOB = 55 degrees, then ABO = 90 - 55 = 35 degrees

Irene made a mistake when she solved this inequality:
just olya [345]

Answer:

she messed up on step two because she has to subtract 10 from both sides

Step-by-step explanation:

step 1: -6(x+3)+10<-2

step2:-6(x+3)+10-10<-2-10

step3: -6(x+3)<-12

step4: (-6)(x+3)(-1)≥(-12)(-1)

step5:6(x+3)>12

step6:divide both sides by 6

step7:simplify and subtract 3 from both sides and then simplify again
