Can someone help with this math problem pleaseeee
Explanation:
The square root undoes the squaring operation.
Think of a square that is 1 ft by 1 ft. Its area would be 1*1 = 1 sq ft.
Now imagine you told your friend "the area is 1 sq ft" and you didn't relay the side lengths. Your friend would use the square root to find the side length is 1 ft.
I'm not sure why your teacher is using plus minus notation when that is not correct. Saying [tex]\sqrt{1} = \pm 1[/tex] is not true. The result of a square root is simply one value only. If your teacher meant [tex]\pm \sqrt{1} = \pm 1[/tex], then it would be a true statement; however, there's no need to involve negative numbers for this problem.

Which quadratic equation is equivalent to (x – 4)2 – (x – 4) – 6 = 0?
(u – 4)2 – (u – 4) – 6 = 0 where u = (x – 4)
u2 – (u – 4) – 6 = 0 where u = (x – 4)
u2 – 16 – u – 6 = 0 where u = (x – 4)
u2 – u – 6 = 0 where u = (x – 4)
Answer:
see below.

You're an automotive body repairer who is writing an estimate for a customer. You
figure the repair work will cost about $450.00 before tax. If the tax rate is 6%, how
much will the customer pay after tax?
$477.00
$720.00
$588.00
Answer:
$100.70
Step-by-step explanation:
The difference between the total price ($434.50) and the sales price ($415) is the tax ($19.50). To find the sales tax as a percentage of the sales price, divide the sales tax by the sales price and then multiply by 100:

Hope its Helps youWhat is The longest line segment that can be drawn in a right rectangular prism that is 13 cm long 12 cm wide and 11 cm tall
Answer:
13√2
Step-by-step explanation:
The longest segment that can be drawn is a "diagonal" connecting two opposite "corners" at the top and bottom.This is similar to finding the length of a diagonal of a rectangle using the Pytagoren Theorem. However, this distance is in 3-space and is given by:d =√(152 + 82 + 72) = √338 = √(169 * 2) = 13√2 cm.

Three students are playing a video game. Each player is randomly
assigned a character from a collection of characters that includes
5 blue, 6 green, and 3 red characters. After each character is picked,
it is not replaced in the collection.
1. What is the probability that the first player does not get a blue character?
Answer:
The probability the 1st player does not get a blue chracter is 9/14.
Step-by-step explanation:
So there is a total of 14 characters.
9 of them are not blue
9/14 = .642857 (~64%, not the answer since it's not asking for percents)
The probability the 1st player does not get a blue chracter is 9/14.

DIVIDE -2 to BOTH SIDES
-2x/-2 = 100/-2
CANCEL out: -2/-2 because it give you 1
KEEP: 100/-2 because it help solve for the x-value (mainly give you it)
NEW EQUATION: x = 100/-2

Point L is on line segment KM. Given LM = 5 and KM=9, determine the length KL.
Answer:
KM=LM+KL. If KM is 9 and LM is 5, then KM-LM=KL. So 9-5=4. KL is 4.
Step-by-step explanation:
The value of KL will be equal to 4 in the line segment KM.
What is a line segment?A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.
Given that point, L is on line segment KM. Given LM = 5 and KM=9. The value of the line segment KL will be calculated as below:-
KM = LM + KL.
If KM is 9 and LM is 5, then,
KM-LM=KL.
KL = 9-5=4.
KL = 4
Therefore, the value of KL will be equal to 4 in the line segment KM.

The population of Florida has increased, on average, at a rate of 8% per year since 1953. In 1993, the population of Florida was 13 million.
What was the population in 1953?
*show work & will give brainliest*
Answer:
598,402
Step-by-step explanation:
Let y = population at year x
x is the number of years since 1953, so for 1993, x = 40
a = population in 1953
y = a(1.08)^x
In 1993, the population is 13,000,000, so y = 13,000,0000 when x = 40.
13,000,000 = a(1.08)^40
13,000,000 = 21.7245a
a = 598,402
Answer: 598,402

Solution:
Note that:
Circumference = 50.24 ft = 2πr = πdDia. = 16 ft.Divide the diameter both sides.
50.24 ft = πd=> 50.24/d ft = πd/d=> 50.24/d ft = πSubstitute the diameter in the equation.
=> 50.24/16 = π (Option A)Mary wants to have $8500 to travel to South America when she is 21. She currently has $6439 in a savings account earning 4% annual compound interest.

Step-by-step explanation:

e^.04= 1.0408 = 6439 x (1.0408^8) = 8,867.33.
the first one would be if she is receiving multiple payments ove the year, and the second one is just the "4% commended annually per year". its been a minute since ive actually had to do this, but that seems right to me. so she will have enough.
