What is equal to the expression square root of 40/2
Answers
First you would simplify what's in the square root, to get root 20. If you want the exact number, and not the approximation, you would take out whatever squares are in that number (20=2*2*5) so your answer is 2root5.
However, if you want the approximation, simply plug it into your calculator and get 4.18154055.

Step-by-step explanation:
Note that 1/√(2) is equal to √(2)/2:
1/√(2) = √(2)/2
So we're given that sin(x-20) = √(2)/2
The only place on the unit circle where sin() is equal to √(2)/2 is at π/4 and 3π/4.
That means the value inside the sine must be equal to π/4 and 3π/4:
since sin(π/4) = √(2)/2 and sin(π/4) = √(2)/2
then,
sin(π/4) = sin(x-20) and sin(π/4) = sin(x-20)
You set the inside of the parentheses equal to each other and solve for x.
You can also add a +2πk at the end since all sinusoidal graph repeats every 2π.

Ricky’s square yards mowed:
Ricky’s time (hr.):
Answers
Final answer:
To find Ricky's values, set up a proportion and solve for Ricky's square yards mowed and time.
Explanation:
To find the values for Ricky, we can use a proportion. Since Jake mowed 216 sq.yd. in 3 hr, we can set up the proportion as 216/3 = Ricky's square yards mowed/2. To solve for Ricky's square yards mowed, we can cross multiply and divide: 216 * 2 = 3 * Ricky's square yards mowed. Therefore, Ricky's square yards mowed = 432 sq.yd. Next, we can find Ricky's time by setting up another proportion: 216/3 = 432/Ricky's time. Cross multiplying and dividing gives us Ricky's time = 6 hr.

Final answer:
The sandwich shop offers a total of 45 different sandwich combinations based on the given options of meats, cheeses, and breads. Each sandwich consists of one type of each category.
Explanation:
The question asked is related to the concept of combinations in mathematics. It gives a variety of choices for making a sandwich - 5 types of meats, 3 types of cheeses, and 3 types of breads. Assuming that each sandwich will have one meat, one cheese, and one type of bread, we can calculate the total combinations by multiplying the number of options in each category together. Combinations are used when the order of selection does not matter.
So, the total number of sandwich combinations would be 5 (meats) * 3 (cheeses) * 3 (breads) = 45 different sandwich choices.

3(x - 4) - 14 = 2(x - 7) + 6
Answers
The final result is x = 18.
⇒ 3x+ 3(-4) -14= 2x+ 2*7+ 6 (distributive property)
⇒ 3x -12 -14= 2x -14+ 6
⇒ 3x+ (-12 -14)= 2x+ (-14+ 6) (combine like terms)
⇒ 3x -26= 2x -8
⇒ 3x -2x= -8+ 26 (inverse operation)
⇒ x= 18
Final answer: x= 18.
