Answer:
It simply means getting rid of the square root or radical in the denominator
Step-by-step explanation:
Rationalizing the denominator simply means getting rid of the square root or radical symbol in the denominator thereby making the denominator to be just a whole number.
For example if we want to rationalize the denominator in; 3/√2
We will multiply the numerator and the denominator by √2 to get rid of the radical in the denominator which is the square root sign.
Thus;
(3/√2) × (√2)/(√2)
This gives;
(3√2)2
Answer:
"To rationalize the denominator means to eliminate any radical expressions in the denominator such as square roots and cube roots." It is done usually by multiplying both numerator and denominator by the radical expression or another expression including the radical to be eliminated.
Step-by-step explanation:
John belongs to a boating club that rents sailboats for $60 for the first hour and $20 for each additional hour. After renting a boat one day, he owed the boating club a fee of $140.
Write and solve an equation to find how many hours he kept the boat.
Answer:
4 Hours
Step-by-step explanation:
The original boating fee is $60 then you add $20 per hour so 20 x 4 = 80
80+60=140 $140
Answer: 140=60+20x. He kept the boat for 4 hours
Step-by-step explanation:
x=hours
y=final cost and the final cost is $140
to find x you would use the equation: 140=60+20x
you would first subtract 60 from both sides and you would get:
80=20x
Now you would divide 20 from both sides
So x is 4

Decrease £120 by 12.5%
Answer:
£ 105.
Step-by-step explanation:
Since it is required to decrease £ 120 by 12.5%, to perform this subtraction the following mathematical operation must be performed:
100 - 12.5 = 87.5
100 = 120
87.5 = X
87.5 x 120/100 = X
10,500 / 100 = X
105 = X
Thus, decreasing £ 120 by 12.5% you get a total of £ 105.

If 50-3x=x-26, then x=
Answer:
x=19
Step-by-step explanation:
50 - 3x = x -26
50-3x-50=x-26-50
-3x=x-76
-3x-x=x-76-x
-4x= -76
x= -76/-4
x=19

Answer:
b, c, d -- (all but the first)
Step-by-step explanation:
The key take-away regarding what relation is or is not a function is the following: a function has no repeated x-values.
The x-values in the table are -3, -1, 0, 2, so any suggested ordered pair with one of those as an x-value cannot be added to the table. The only such pair in the list is the first one (-3, 4). It cannot be added. All of the remaining three pairs can be added and the relation will remain a function.

Help........Betty wants to bake the perfect cookie. She wants to determine the ideal temperature at which to bake the cookies. She has enough batter to make 60 cookies. She decides to randomly assign 15 cookies to be baked at 300°, 15 at 325°, 15 at 350°, and 15 at 375°. The baking time for each batch is 12 minutes. Which statement about the randomization for the completely randomized design is correct? Betty should place the first 15 balls of cookie dough that she scoops from the batter on a tray, and those will be baked at 300°. The next 15 will be placed onto a second tray to be baked at 325°. She should continue in this manner until all 60 cookies have been placed on trays. Betty should scoop a ball of cookie dough from the batter, and then roll a die. Numbers 1–4 would indicate at which temperature the cookies will be baked, and 5–6 would indicate that she should roll again. She should repeat this process until all 60 cookies have been allocated. Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated. Betty should place the first cookie on a tray to be baked at 300°. The second cookie will go on a tray to be baked at 325°, the third will go on a tray to be baked at 350°, and the fourth will go on a tray to be baked at 375°. She will continue placing the cookies in this pattern until all 60 cookies are on trays to be baked.
Answer: Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated.
Step-by-step explanation: I just got it correct on Edge :)
The true option about the randomized design is (c) Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated.
The given parameters are:
[tex]\mathbf{n = 60}[/tex]
[tex]\mathbf{Batches = 4}[/tex]
[tex]\mathbf{Cookies= 15}[/tex] ---- the number of cookies in each batch
[tex]\mathbf{Temperature= 300,325,350,375}[/tex]
To randomly assign the cookies to the given temperatures, all cookies have to be subjected to the same conditions (except the difference in the temperature).
This means that, she can bake all the cookies at once at different temperatures, while noting down the cookies with a given number.
Hence, the true option is (c)
