Answer:

Option D

m∠ABC=35\°

Step-by-step explanation:

we know that

The inscribed angle measures half that of the arc comprising

In this problem

m∠ABC is the inscribed angle

so

m∠ABC=\frac{1}{2}(arc\ AC)

arc\ AC=70\° -------> by central angle

substitute

m∠ABC=\frac{1}{2}(70\°)=35\°

The difference between the price that DeMarkus thought he should pay and the price that the store charged him is $24

The question provided is incomplete. Here is the complete question : DeMarkus says that a store overcharged him on the price of the video game he bought. He thought the price was marked  1/4 of the original price, but it was really  1/4 off the original price. He misread the advertisement. If the original price of the game was $48 , what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him?  A. $28.50B. $36.00C. $42.50D. $24.00

The first step is to determine the price DeMarkus thought the price of the videogame was = 1/4 of the original price

1/4 x $48 = $12

The second step is to determine the actual discounted price.

Actual discounted price = original price = (1/4 of the price)

48 - (1/4 x $48 = $12)

$48 - $12 = $36

The third step is to determine the difference in the prices

$36 - $12 = $24

makkiz [27]

Answer: The two sides are 15m and 10m.

Step-by-step explanation:

Area = l x w

150 = l x w

There are two solutions for l

l 1= P/4+1/4√P2﹣16A

=50/4+1/4·√50^2﹣16·150=15m

l2 = P/4﹣1/4√P2﹣16A

=50/4﹣1/4·√50^2﹣16·150=10m
