Which equation applies the associative property of multiplication? (−1/2⋅4/7)+(−1/2⋅2/3)=−1/2⋅(4/7+2/3) (−9/4⋅3/2)⋅(6/3⋅5/7)=

−9/4⋅(3/2⋅6/3)⋅5/7 −6/5−(5/3−1/4)=(−6/5−5/3)−1/4 8/9⋅7/4⋅(−5/8)=8/9⋅(−5/8)⋅7/4

What’s the correct answer for this?

Oxana [17]

Answer:

x = 5

Step-by-step explanation:

Since TV bisects (equally divides) EF hence <EKT = 90°

Also <EKT = 5x+65

So

5x+65 = 90

5x = 90-65

5x = 25

Dividing both sides by 5

x = 5

Please help me find the area of the triangle in terms of x!

Vitek1552 [10]

Answer:

$Solution,\\Area~of~triangle=\frac{1}{2} (base)(height) = \frac{1}{2}(2x+\frac{1}{4}) (x-8)\\~~~~~~~~~~~~~~~~~~~~~~~~ =\frac{1}{2}[2x^2-16x+\frac{1}{4}x-\frac{1}{4}(8)]\\ ~~~~~~~~~~~~~~~~~~~~~~~~ =\frac{1}{2}[2x^2-\frac{63}{4}x - 2]\\~~~~~~~~~~~~~~~~~~~~~~~~=x^2-\frac{63}{8}x-1$

A ship is 1.4° off course. If the ship is traveling at 14.0 miles per hour, how far off course will it be after 2 hours?

sesenic [268]

Answer:

about 0.7 miles

Step-by-step explanation:

When you draw a diagram of the problem, you see that the shortest distance back to the course is the distance traveled times the sine of the angle:

distance off course = (14 mi/h)×(2 h)×sin(1.4°) ≈ 0.684 mi

The ship is about 0.7 miles from its intended course.
