Answer:
K is either 9 or 1
Step-by-step explanation:
Sqrt((0 - 3)² + (k - 5)²) = 5
Square both sides
(0 - 3)² + (k - 5)² = 5²
(0 - 3)² + (k - 5)² = 25
-3² + (k - 5)² = 25
9 + (k-5)(k-5) = 25
9 + k² - 5k - 5k + 25 - 25 = 0
k² - 10k +9 = 0
k² - 9k - k + 9 = 0
k(k - 9) - 1(k - 9) = 0
k - 1 = 0 ; k = 1
k - 9 = 9; k = 1
K = 9 or k = 1
K is either 9 or 1
The answer, and work shown.

Convert the element into a fraction:
=3/1 divided by 1/3
Apply the fraction rule:
=3/1 * 3/1
Apply rule a/1:
=3*3
Multiply the numbers: 3*3=9
=9
=9-9+1
Add and subtract (left to right):

I'm not sure if this is exactly right because the wording of the problem is confusing.
Answer:
a) Number of square feet of wallpaper for bedroom = 12x^2 - 21
b) Number of square feet of wallpaper for living room = 14x^2 - 42
c) Total amount of wallpaper needed = 26x^2 - 63
d) 107 more sq ft of wallpaper will be needed for the living room than bedroom.
Step-by-step explanation:
a) First find the area of each wall.
Length: 3x, Width: 3x, Height: x
(3x × x) + (3x × x) + (3x × x) + (3x × x) = 3x^2 + 3x^2 + 3x^2 + 3x^2 = 12x^2
12x^2 represents the amount of wallpaper needed, including the door. Find the area of the door and subtract it from this value.
3 × 7 = 21
12x^2 - 21 = Total sq ft of wallpaper needed for bedroom
b) First find the area of each wall.
Length: 4x, Width: 3x, Height: x
(4x × x) + (4x × x) + (3x × x) + (3x × x) = 4x^2 + 4x^2 + 3x^2 + 3x^2 = 14x^2
14x^2 represents the amount of wallpaper needed, including the door. Find the area of both doors and subtract it from this value.
3 × 7 = 21 × 2 = 42
42x^2 - 42 = Total sq ft of wallpaper needed for living room
c) Add the two expressions to find the total amount of wallpaper needed.
(12x^2 - 21) + (42x^2 - 42) = 26x^2 - 63
26x^2 - 63 = Total sq ft of wallpaper needed for both rooms
d) Plug x = 8 into the equations found in part a and b.
12(8)^2 - 21 = 747
14(8)^2 - 42 = 854
Subtract these answers to find the difference in amount.
854 - 747 = 107
The living room needs 107 sq ft more of wallpaper than the bedroom

-2x + 4 = 12
Explain what mistake did he make
Answer:
X=-4
Step-by-step explanation:
-2x + 4 = 12
so what you would do is subtract 4 from itself and 12
4 - 4 = 0
12 - 4 = 8
then we have-
-2x = 8
we then divide 2 from 2 and 8
2 divided by 2 = 0
2 divided by 8 = 4
so x = -4

Okay I put -646/15 but it’s wrong can someone help me
Answer:
-30 5/6
Step-by-step explanation:
You are adding two negative numbers, so add their absolute values and make the answer negative.
-28 1/3 + (-2 1/2) =
= -(28 1/3 + 2 1/2)
We add the absolute values 28 1/3 and 2 1/2. We need a common denominator for the fractions. The LCD of 2 and 3 is 6.
= -(28 + 2 + 1/3 + 1/2)
= -(30 + 2/6 + 3/5)
= -(30 5/6)
= -30 5/6

Satish's register shows a deposit on February 4 in the amount of $150.00, an atm withdrawal on February 5 in the amount of $180, and another deposit on February 7 in the amount of $225.56. What should Satish's balance in his register be? A. $610.82, B.$792.91, C.$910.82, or D.$947.14
Answer:
Balance = $195.56
Step-by-step explanation:
Credit:
Feb 4 deposit = $150.00
Feb 7 deposit = $225.56
Total credit = $375.56
Debit:
Feb 5 ATM withdrawal = $180
Total Debit = $180
Balance = credit - debit
= $375.56 - $180
= $195.56
Balance = $195.56
The answer is not included in the option. It is either the options are not correct or the values in the question are not correct. Please recheck
Satish's balance in his register would be $195.56
Equation
Equation is an expression used to show the relationship between two or more numbers and variables.
Credit:
Feb 4 deposit = $150.00
Feb 7 deposit = $225.56

Debit:
Feb 5 withdrawal = $180

The measure of arc AC from the given circle is 55 degree. Therefore, option C is the correct answer.
What is relation between angle at the center and the angle at the circumference?The angle subtended by an arc at the center is twice the angle subtended at the circumference. More simply, the angle at the center is double the angle at the circumference.
Given that, in the circle, diameter AB is parallel to chord CD.
Here, measure of arc CD is 70°.
Since, AB is diameter, than the measure of arc AB is 180°.
Now, 180°-70°=110°
So, measure of arc AC = measure of arc CD = 110°/2
= 55°
Therefore, option C is the correct answer.

Verbal contracts are discouraged generally, because: b. without a physical signature, they can be very difficult to enforce.
What is a Verbal Contract?A verbal contract, which can also be referred to as a parol contract, is a verbal agreement reached between two parties without any form of written documentation.
A verbal contract is an agreement that comprises most of the elements contained in a normal contract and can be legally binding, however, it is without any signature which makes verbal contracts difficult to keep as any of the party involved can deny consenting to any of the agreed terms.
Therefore, verbal contracts are discouraged generally, because: b. without a physical signature, they can be very difficult to enforce.

A Cylinder has a radius of 10 feet and a height of 11.4 feet what is the approximate volume of the cylinder?
Answer:
3579.6 [tex]ft^{3}[/tex]
Step-by-step explanation:
First, write out the equation used to find the volume of a cylinder and place the values in place of the variables. The equation is [tex]\pi[/tex][tex]r^{2}[/tex]*h where r is the radius and h is the height. When we place the values of the variables into the equation we get: [tex]\pi[/tex][tex]10^{2}[/tex]*11.4. Next, square 10 to get 100. This would give you 3.14*100*11.4. When you multiply this together you get 314 times 11.4 which gives you 3579.6 ft cubed.
I believe it's 3581.42 (if the answer needs be rounded to 2 decimal places.
Step-by-step explanation:
area of circle = r×r×π
area of circle × height = volume
10 × 10 × π = 314.16
314.16 × 11.4 = 3581.42

A: 575 ÷115

C: 5,750 ÷ 115
D: 575 ÷ 1,150
Answer:
A and B, but I’m gonna explain it the best I can too.
Step-by-step explanation:
5.75 divided by 1.15 is the same as answer A, since all you are doing is taking away the periods, making it whole numbers.
Again 5.75 divided by 1.15 is the same as B as well, Since it is the same just without the periods and an added zero at the end of each.
This Is so that they are both all equivalent by being whole numbers, but whatever you do to one numbers in the expression that you think is the answer you have to do to the other numbers in the expression
they have to add up completely the same.
