The regular price of a computer is $1200 and the regular price of a printer is $300. The regular price of a computer is 1200 dollars and the regular price of a printer is 300 dollas. An electronics store has a promotion that offers a 40% 40 percent discount on the printer when the computer is purchased at the regular price. What is the total cost of the computer and the printer at the promotional price?

$1380

Step-by-step explanation:

The electronics store offers a 40% discount on the printer only when the computer is purchased at the regular price.

Discount on the Printer = 40% of $300 =0.4 X 300 =120

Promotional Price of the Printer = $300-120 =$180

Therefore, the total cost of the computer and the printer at the promotional price

=Regular price of a computer + Promotional Price of the Printer

=1200+180

=$1380

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
