Answer:this one is hard

Step-by-step explanation:

Answer:

Area = 1/2 (Base) (Height)

Area = 1/2 (12 in) (8 kn)

Area = 1/2 (96 in)

Area = 48 in^2

Volume = (Area) (Length)

Volume = (48 in^3) (13 in)

Volume = 624 in^3

The error interval for d is from 391.6 to 391.9 and 392.1 to 392.4.

We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, The depth 'd' of a lake is 392 m, rounded to the nearest integer.

Now a number rounded to the nearest integer to 392 is only possible when the number is less than 392.5 which is 392.4 and greater than 391.5.

Answer:

Natalie saved 16%

Step-by-step explanation:

Natalie saved 16% because 20 divided by 125 is 0.16

When we find percentages our goal is to get something like 0.24 which would mean 24% or 0.14 or 14% in this case it is perfect because we immediately see 0.16 or 16% leaving us with our answer, Natalie got 16% off her new phone.

Answer:

16%

Step-by-step explanation:

so that is the original number subtracted by a percentage, but that percentage is then multiplied by 125

125-(x/100)125=125-20

x=16

Answer:

He can buy up to 7 games

Step-by-step explanation:

200 divided 25.50 is 7.84 so therefore he can only buy 7

Answer:

7

Step-by-step explanation:

since it costs 25.50 dollars for each game say that x is each game and 25.50 times x equals the amount of money he spent on his games.

since he only has 200 dollars the inequality has to be greater than or equal to 25.50x

200>=25.50x

7.843>=x

so he can only buy up to 7 games

Answer: x=-5

Step-by-step explanation:

You would have to do the inverse to “undo” the equation.

So first you would do -7-3=-10

Then you would do -10/2=-5 to find x

=========================================

The diagram shows:

Recall that the area of a parallelogram is equal to the base times height

area = base*height

We're told that the area is 117 square units, so that means 13x = 117.

Divide both sides by 13 to isolate x

13x = 117

13x/13 = 117/13

x = 9

The height of the parallelogram is 9

Note how:

area = base*height = 13*x = 13*9 = 117

which helps confirm we have the correct height value for x.

Answer:

60° 60° 60°

60°

Step-by-step explanation:

In any triangle, the sum of its interior angles is 180°, and 60+60+60=180.

As for the other question, we can see that angle5=angle1, and angle6=angle2, due to the parallelism of the lines.

Angle5+angle6=180°, therefore

Angle6=180-120=60°=angle2

Answer:

θ = [tex]\frac{\pi }{3}[/tex] (60° )

Step-by-step explanation:

Using the identity

sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x

Given

cos²θ - sin²θ = 2 - 5cosθ

cos²θ - (1 - cos²θ) = 2 - 5cosθ

cos²θ - 1 + cos²θ = 2 - 5cosθ

2cos²θ - 1 = 2 - 5cosθ ( subtract 2 - 5cosθ from both sides )

2cos²θ + 5cosθ - 3 = 0 ← in standard form

(cosθ + 3)(2cosθ - 1) = 0 ← in factored form

Equate each factor to zero and solve for θ

cosθ + 3 = 0

cosθ = - 3 ← not possible as - 1 ≤ cosθ  ≤ 1

2cosθ - 1 = 0

cosθ = [tex]\frac{1}{2}[/tex] , so

θ = [tex]cos^{-1}[/tex] ([tex]\frac{1}{2}[/tex] ) = [tex]\frac{\pi }{3}[/tex] ( or 60° )
