Alright, lets get started.

One report takes to file an average of = 45 minutes

Means 12 reports takes to file time = 12 * 45 = 540 minutes

12 reports filing total time = 540 minutes

We are asked to find time to file 75 % of them.

Which means 75 % of 540

= 540 * 75/100

= 540 * 0.75

= 405 minutes

We could convert it into hrs dividing with 60.

405 / 60 = 6.75 hrs

Means it will take 6.75 hrs to file 75% of them: Answer

Hope it will help :)

A package of 85 paper plates costs $8.08, while a package with 55 paper plates costs $4.40. Which is the better buy? Round your
morpeh [17]

Answer:

55 paper plates for $4.40 is your best buy because the price for unit is $0.08

Step-by-step explanation:

First find the price for unit of each option

we have :

85 paper plates for $8.08

55 paper plates for $4.40

To find the price per unit we divide  8.08 ÷85 = .09 rounded to the nearest cent  is .10

and 4.40 ÷ 55 = .08

Therefore, the best buy is $.08  or 55 paper plates for $4.40

What is the length of Line segment A B? Round to the nearest tenth. Triangle A B C is shown. Angle A C B is a right angle and an
Amiraneli [1.4K]

Answer:

D.) 38.6 m

Step-by-step explanation:

Use the cosine ratio:

cosine=\frac{adjacent}{hypotenuse}

Because we are given the measure of an angle and the length next to it (adjacent), and we need to find the hypotenuse (the hypotenuse is NEVER considered the adjacent side). Insert the values:

cos75=\frac{10}{x}

Now isolate the variable. Multiply both sides by x:

x(cos75)=x(\frac{10}{x} )

The x's on the right side cancel each other out. Simplify:

x*cos75=10

Now divide both sides by cos75°:

\frac{x*cos75}{cos75} =\frac{10}{cos75}

The cos75° on the left side cancels each other. Simplify:

x=\frac{10}{cos75}

Insert this value into a calculator to simplify the value of x:

x=38.6

The hypotenuse is 38.6 m.

As the sine rule states,

A/sina = B/sinb = C/sinc .

in the diagram, there are two identified sides and if you use the sine rule, you can find the opposed angles easily.

there are:

side a, with angle â .
side b, with angle b.

so the answer is C.

if you input these into the sine rule, it would be:

a/ sin a = b/sin b
