Multiplying radicals is the same procedure as multiplying whole numbers, when you multiply, you get a result, and that result always equal to itself, which is what we know as "Symmetry Property".

Answer:
50
Step-by-step explanation:
They need to sell 50 of them in order to raise $1000. Its simple math all you have to do is divide 1000 by 20 and poof you have the answer.
Assuming the house is parallel to the ground, your triangle is made up by the house, the ground, and the ladder. Using sin(x) = opposite/hypotenuse on the angle 70 degrees, you would have sin(70) = 20/x (because 20 is the side opposite of the angle connecting the ladder and the ground)
--> simplify sin(70) * x = 20 --> x = 20 / sin(70
--> substitute (and make sure your calculator in in degrees) x= 21. 284
Out of 124 students, only 31 students are taught to buy their lunches in the cafeteria.
<u>Step-by-step explanation:</u>
It is given that,
The 25% of 124 students are taught to buy their lunches in cafeteria.
Therefore, the total number of students taught to buy their lunches in cafeteria is 25% of 124.
<u>To find the number of students who are capable to buy lunches in cafeteria:</u>
- Replace the % symbol into the numeric form.
- The % is represented by 1 ÷ 100.
The 25% of 124 students is written as,
⇒ 25×(1/100)×124
⇒ (1/4)×124
⇒ 31
The number of students taught to buy lunches in the cafeteria out of 124 students is 31 students.
