Aprox 12. On Average, you can read 20 pages in 30 minutes and divide 20 by 30 you get 0.6 and 0.6 x 20 is 12.

Answer: There is no exact answer. Students read at different rates; books, magazines and web pages have different numbers of words per page and levels of difficulty.

Step-by-step explanation: You would need some average rate for the class. Or conduct a survey to ask students how many pages they read in 20 minutes. Or design and experiment to determine students' reading rates and control the type of book and level of difficulty.

WILL GIVE BRAINLIEST!!!!!!!!!!!!! the answer for question one was x=30

VMariaS [17]

Answer:1

1. $x = 30$

2. ∠ABC = 120°, ∠BCD = 90°, ∠CDA = 60°, ∠DAB = 90°

Step-by-step explanation:

It's important to note here that the measure of all interior angles in a quadrilateral will add up to 360°

We know this using the formula $(n-2)\cdot 180$ , a 4 sided figures angles will add up to

$(4-2)\cdot 180\\\\2\cdot 180\\\\360$

This means that all of the angles (4x, 3x, 2x, 3x) will add up to 360.

$4x + 3x + 2x + 3x = 360$

Combine like terms:

$12x = 360$

Divide both sides by 12:

$x = 30$

We know now substitute x for 30 in for all of the side lengths.

∠ABC = 4x = $4\cdot 30 = 120$ °

∠BCD = 3x = $3\cdot 30 = 90$ °

∠CDA = 2x = $2\cdot 30 = 60$ °

∠DAB = 3x = $3\cdot 30 = 90$ °

Hope this helped!

For a particular angle Θ, the cosine function f(x) = a cos b(Θ) has the following values within one cycle of the function:

expeople1 [14]

If f(θ) = a cos(bθ), then from the first condition we find

f(0) = 3 ⇒ a cos(0) = 3 ⇒ a = 3

Together with the other conditions, it's evident that f(θ) has a period of π, so

2π/b = π ⇒ b = 2

so that

f(θ) = 3 cos(2θ)

Evaluate g(10) of g(x) =1/2x -4

umka2103 [35]

Answer:

g(x)= 1

Step-by-step explanation:

$g(x) = \frac{1}{2} x - 4 \\g(10) = \frac{1}{2} (10) = 5 \\ 5 - 4 = 1$
