Answer:

DM = 12

Step-by-step explanation:

I'm not very good with explaining but since MB is 12, vertex to the centroid which is M is 2/3 of the median, which is the line. So, since 12 is the 2/3 of the median, then DM would also be 12, since it's from vertex to centroid. Hope this helped.

Winter coats are marked 70% off on February 1st. If a coat costs 57.75 on January 31st, how much will it cost on February 1st.

Answer:

So Price after discount would be 17.5 on February 1st

Step-by-step explanation:

Given:

Original Cost  =57.75

Off Price = 70%

To Find:

Price after discount = ?

Solution:

We have to find the price after discount which is given by the formula

Price after Discount = Original Cost - Discount Price

We have to find the value of discount price

Discount Price = off Price * Original Cost

Putting in the values

Discount Price = 70 % * 57.75

it becomes

Discount Price =\frac{70*57.75}{100}

It becomes

                         =\frac{4025}{100}

                                = 40.25

Now

Price after Discount = Original Cost - Discount Price

Putting in the values

it becomes

Price after Discount = 57.75-40.25

                                   = 17.5

So Price after discount would be 17.5 on February 1st

The base of a right circular cylinder has a diameter of 5.00 inches. Sally measured the circumference of the base cylinder and r
LUCKY_DIMON [66]

Answer:

The percent of error in her measurement is 1.3%

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=\pi D

where

D is the diameter

we have

D=5\ in

assume

\pi=3.14

substitute

C=(3.14)(5)=15.7\ in ----> This value represent the 100% (theoretical value)

Find the difference between the theoretical value and the measured value

15.7-15.5=0.2\ in

Find the percentage by proportion

15.7/100=0.2/x\\ x=100*0.2/15.7\\ x=1.3\%
