A long year end status report for work is 136 pages long. You need to print 19 copies for a meeting next week. How much is the p

tatyana61 [14]

Answer:

$19.60

Step-by-step explanation:

Given data

number of pages= 136 pages

number of copies = 19 copies

Hence 19 copies make a total of = 136*19

=2584 pages

hence if 500 pages cost $3.80

then 2584 pages will cost x

cross multiply

500x= 2584*3.8

500x=9819.2

Divide both sides by 500

x= 9819.2/500

x= 19.6384

x=$19.60

It will cost $19.60

In circle pp, ad¯¯¯¯¯ad¯ is a diameter and bc¯¯¯¯¯bc¯ is perpendicular to ad¯¯¯¯¯ad¯ at ee. if pd=7pd=7 and ae=4ae=4, find cece.

kvv77 [185]

See the attached figure.

<span>ad is a diameter of the circle with center p
</span>
∵ pd = radius = 7 ⇒⇒⇒ ∴ ad = 2 * radius = 2 * 7 = 14
∵ ae = 4 ⇒⇒⇒ ∴ ed = ad - ae = 14 - 4 = 10
∵ ad is a diameter
Δ acd is a triangle drawn in a half circle
∴ Δ acd is a right triangle at c
∵ bc ⊥ ad at point e
By applying euclid's theorem inside Δ acd
∴ ce² = ae * ed
∴ ce² = 4 * 10 = 40
∴ ce = √40 = 2√10 ≈ 6.325
