±√121 what is the answer
Answers
Answer:
±√121 = ±11 (11, -11)
Step-by-step explanation:
1.First, find two equal numbers multiplied by each other to get 121:
This will be 11×11, so the answer for the square root is +11 or -11.
2. Or you can find the square root of a number using this method:
draw a line splitting two sides from each other.then, write the number inside the square root on the left side of the line.after that, on the right side, write a number that can be divided by 121 ( it should be a whole number and a prime number).write the answer to the division on the left side of the line.next, rewrite the two steps above by writing a number that can be divided by the answer of the division.stop writing the number when you get to number one on the left and right sides.finally, match every two equal number together to make it on the number and multiply them together to get the answer for the square root.you can understand it more from the picture below, I also did another example for this method.

Benita buys 2 shirts for the same price, s. The sales tax rate is 6.5%.
Write an expression to represent the total cost of the shirts in two different ways.
Enter the correct answers in the boxes.
Answers
Answer:
2S + 0.065(2S)
Step-by-step explanation:
Since S is the price of a shirt, the price of two shirts would be 2 x S = 2S
a tax is a compulsory sum levied on goods and services. tax increases the price of a good
The price of the 2 shirts would increase by the amount of tax ; 0.065(2S)
This gives = 2S + 0.065(2S)
Alternatively, since two shirts were purchased, the amount of tax would be twice 0.065 - 0.13 - S + S + 0.13S
We want to write two expressions that represent the total cost of the shirts, the expressions are:
Cost = P*(1.065) + P*(1.065)
cost = P*2.13
We know that Benita buys two shirts for the same price, P.
Then at this moment. the total cost is just:
cost = 2*P
Now we apply a 6.5% tax, then the price increases by 6.5%, this is written as:
P' = P*(1 + 6.5%/100%) = P*(1.065)
Then the total cost is twice that amount, written as:
Cost = P*(1.065) + P*(1.065)
This can be one of the two expressions.
Now to get the other expression, we just simplify the above one:
cost = 2*P*(1.065) = P*2.13

The average of six numbers is 4. If the average of two if those numbers is 2,what is the average of the other 4 numbers?
Answers
Answer: Average of other 4 numbers =5
Step-by-step explanation:
Sum of n numbers = Average of n numbers x n
Given: Average of 6 numbers =4
so sum of 6 numbers = 6x 4 = 24
Average of 2 numbers = 2
Sum of 2 numbers = 2 x 2 =4
Sum of rest of 4 numbers = sum of 6 numbers - Sum of 2 numbers
= 24-4
=20
Average of 4 numbers = [tex]\dfrac{20}{4}[/tex]
i.e. Average of 4 numbers =5

the measure of the angle is 72
x=36
Step-by-step explanation:
we can make an algebraic equation using the info given
2x+80=152
2x=72
x=36
the measure of the angle is 72
Answer:
x = 36, the measure of the angle is 72
Step-by-step explanation:
We can see this because Angle 2x and Angle 72 are verticle angles. Based on this information we know that verticle angles are congruent to each other, meaning the are the same. So that leaves us with an equation to figure out x.
2x = 72
[tex]\frac{2x}{2}[/tex] = [tex]\frac{72}{2}[/tex]
