X= 240
-----
Equation:
anti + anti = anti
0.60x + 0.20*80 = 0.50(x+80)
-----
Multiply thru by 100 to get:
60x + 20*80 = 50x + 50*80
-----
10x = 30*80
x = 3*80
x = 240

Please help me with this question!!
Bess [88]

Answer:

x=16 * cos(46)

Step-by-step explanation:

Well, first let's look at our trig identities. We can set up a cosine function using the given angle:

cos (46^{o} ) = \frac{x}{16} (adjacent/hypotenuse)

Then, multiplying both sides by 16 gives us:

x=16 * cos(46)

Hope this helps!

Jennifer used 0.42 gallons of paint to completely cover a square wall with an area of 168 square feet. Which measurement is clos
Marina86 [1]

Answer:

The answer to this question is: 12.96 ft ≈ 13 ft

Step-by-step explanation:

Data

Area 168 ft²

Length = ?

Volumen = 0.42 gallons

But we do not need the volume of paint because we know that the wall is squared-shape.

Only we need to know the formula to obtain the area of an square.

Formula   area = length²

So            168 = length²

Finally      √168 = length

             length = 12.96 ≈ 13 ft

A wire is to be attached to support a telephone pole. Because of surrounding buildings, sidewalks, and​ roadways, the wire must
ad-work [718]
This situation is a right triangle with the base measuring 18 and the hypotenuse 22.  We are looking for x, the height up the pole that the wire is going to be attached to.  We will use Pythagorean's Theorem to find the missing length.  22^2-18^2=x^2  and  484-324=x^2.  x^2 = 160 so x = 4 \sqrt{10} or 12.65 feet
