Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on. Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry.

You downloaded a video game to your computer. You have a 60-minute free trial of the game. It takes 5 1/6 minutes to set up the

igomit [66]

Answer:

B.

Step-by-step explanation:

Given,

The time for set up the game = $5\frac{1}{6}$ minutes,

Also, the time for each level of game is $7\frac{1}{3\\}$ minutes,

If there are l levels of games,

Then the time taken in all levels of game = $(7\frac{1}{3}) l$ <em> </em>

Hence, the total time ( in minutes ) = Set up time + time in all level

= $5\frac{1}{6} +(7\frac{1}{3}) l$

We have 60-minute of free trial of the game,

So, the total time taken can not be exceed to 60 minutes,

= $5\frac{1}{6} +(7\frac{1}{3}) l\leq 60$

Which is the required inequality.

Option 'B' is correct.

If y = (x-5)(x+7) then what does x equal?

DochEvi [55]

You need to find the GCF (greatest common factor) of 45 and 90, which is 45.

45 times ? gets you 45

? would be 1

45 times 1 equals 45.

45 times ? gets you 90

? would be 2

45 times 2 equals 90

45(1+2) = 45+90 = 135

Help answer please!!

Answer:

h = 19.7 ft.

Step-by-step explanation:

Use the Pythagoras Theorem

$(Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\\\(20)^2=(3.5)^2+(h)^2\\400=12.25+h^2\\400-12.25=h^2\\387.75=h^2\\$

Now we take square root on both sides,

$\sqrt{387.75} =\sqrt{h^2}\\19.69=h\\h=19.7\ ft\\$

so the value of h equals 19.7 ft.
