Answer:

one solution

Step-by-step explanation:

2/3(3y+6)=0

Multiply by 3/2

3/2 *2/3(3y+6)=0*3/2

3y+6 = 0

Subtract 6 from each side

3y = -6

Divide by 3

3y/3  = -6/3

y = -2

A radio transmission tower is 190 feet tall. How long should a guy wire be if it is to be attached 13 feet from the top and is t
gladu [14]

Answer:

343.7 ft

Step-by-step explanation:

The wire is anchored 190 -13 = 177 ft from the ground. That distance is opposite the given angle (31°). The measure you want is the hypotenuse of the triangle with that side and angle measures.

The mnemonic SOH CAH TOA reminds you that the relation between the opposite side, hypotenuse, and angle is ...

Sin(angle) = Opposite/Hypotenuse

Filling in the given information, you have ...

sin(31°) = (177 ft)/hypotenuse

Solving for hypotenuse gives

hypotenuse = (177 ft)/sin(31°) ≈ 343.7 ft

The length of the guy wire should be 343.7 ft.

tangare [24]

Answer:

2 notebooks

Step-by-step explanation:

I understand you already figured out that it was 3 notebooks, but when I calculated it, I believe he could only buy 2...

Personally, I would show my work by first doing the calculation: 2.75[1 notebook price]+ (3[pens/pencils per notebook]*1.10[pen/pencil cost])= $9.075 per notebook and 3 pens

If you then showed that you multiplied 9.075 by 2... you would get $18.15 which is the closest you could get to his limit of $22 without going over

If we applied your answer of 3 notebooks, then the total would be $27.225 which goes over the money limit.

Hope I helped!
