Geometric proofs of segments

Mathematics
1 answer:
Alekssandra [29.7K]3 years ago
3 0

Answer:

The proof is shown below.

Step-by-step explanation:

Given: B is mid point of AC and C is mid-point of BD.

To prove: AD=3AB

It is given that B is mid-point of AC.

⇒ AB = BC               ...(1)

Also, C is mid-point of BD.

⇒ BC = CD               ...(2)

From (1) and (2),

AB = BC = CD

Now, AD = AB + BC + CD

⇒ AD = AB + AB + AB             (∵ AB = BC = CD )

Hence proved.

Hi! I’m stuck on this problem on math! This is 5th grade math. Can anyone help me?

Answer:

The answer is 4.2 kilograms of dog food

Step-by-step explanation:

it says that ray feeds his dog 0.12 kilogram of food each day

he needs for 1 month

1 month = 31 days or 30 days

since 1 day food is 0.12 kilograms you'll have to multiply 0.12 with 1 month

i.e; 0.12*31 or 0.12*30

0.12*31=3.72 and 0.12*30=3.6

since we don't have an option we'll have to choose something bigger than this

therefore, the answer is 4.2
