Step-by-step explanation:

Because you said "estimate," I will be estimating this.

49% rounds up to 50%

A) 7.7 ft<br> b) 13.4 ft<br> c) 10.3 ft<br> d) 12.3 ft
ELEN [110]

Answer:

D. 12.3 ft

Step-by-step explanation:

This problem requires the use of trigonometric ratios. This one specifically uses the cosine ratio as it provides the hypotenuse and is asking for the side that is adjacent to the angle.

cos(40°)=a/16

cos(40°)×16=a/16×16

cos(40°)×16=a

a=12.256 ft

The length of side a is D. 12.3 ft.

Half is a third of it.what is it?
Sati [7]
Let's call 'it' x. 1/2 is equal to one third of x, so we could say that 1/3x = 1/2

Now we just have a simple equation to solve:

1/3x = 1/2
x = (1/2) / (1/3)

Dividing by a rational number (such as 1/3, which is expressed in fraction form) is the same as multiplying by its reciprocal (the reciprocal of a fraction is itself when the numerator and denominator have been swapped). Therefore

x = (1/2) / (1/3) = (1/2) * 3 = 3/2 = 1.5

To check this answer, test the statement. Half is a third of x, where x=1.5:

1.5 / 3 = 0.5 = 1/2

-2 + (–15) = –(2 + 15) what property is this equation
barxatty [35]

Hello.

The answer is: The Commutative property

The Commutative property states that order does not matter. Multiplication and addition are commutative. Commutative is also when you change the order of the equation but its still that same answer.

Have a nice day.
