A

Step-by-step explanation:

Answer:

x is equal to ± 1/2

Step-by-step explanation:

To find x, we simply need to take the square root of both sides:

x²  = 1/4

√(x²)  = √(1/4)

x =  √(1/4)

x = ± 1/2

Answer:

8.5 %

Step-by-step explanation:

The formula used her :

\text{Percent error }=\dfrac{|\text{Estimated value-Actual value}|}{\text{Actual value}}\times100Percent error =

Actual value

∣Estimated value-Actual value∣

×100

Given : A hospital bill is estimated to be $480.00 it ends up actually costing the patient $524.50 .

Then, the percent of Error in the bill will be :

\begin{gathered}\text{Percent error }=\dfrac{|480-524.50|}{\text{524.50}}\times100\\\\=\dfrac{|-44.5|}{524.50}\times100\\\\=\dfrac{44.5}{524.50}\times100\\\\=8.48427073403\approx8.5\%\end{gathered}

Percent error =

524.50

∣480−524.50∣

×100

=

524.50

∣−44.5∣

×100

=

524.50

44.5

×100

=8.48427073403≈8.5%

[Rounded to the nearest tenth]

Hence, the percent of Error in the bill = 8.5%

Step-by-step explanation:

Answer:

x=5

Step-by-step explanation:

36x-20=160

first, find the value of x

add 20 from both sides

36x-20=160

+20 +20

36x=180

then, divide 36 from both sides to get x by itself

36x/36=140/36

x=5

now, plug x into the equation to check your work

36(5)-20=160

multiply 36 and 5

180-20=160

subtract 20 from 180

180-20=160

CUZ PENTHOUSES ARE AT TOPS OF HOTELS

Answer:

Step-by-step explanation:

As given Total Guavas  = 40 ,

3 daughters,

Let   share of Sharon = x

then by given condition ,

Naomi share = x+3                  (3 more then Sharon

Also Kassie share = x+3+10 =x+13     (10 more then Naomi

Now

total shared = total

Naomi + Sharon + Kassie = 40

(x+3) +(x) +(x+13) =40

adding like terms with like we get ,

3x+16=40

3x=40-16

3x=24

x= 24/3

x= 8  

hence Sharon share = x =8

Naomi share = x+3 =8+3 =11

Kassie share = x+13 = 8+13 = 21

Answer:

The equation of the line perpendicular to and passing through its midpoint is equals negative a quarter plus three-quarters.

Answer:

P(H) = 13 ÷ 52

Step-by-step explanation:

The computation of the probability that the first card be the heart is given below:

We assume that each and every card in the deck would be likely to be the first card

Here we assume the Hi that represent the first card drawn be the heart

NOw

P(Hi) = 1  ÷ 52 for

1 < = i < =13.

The H event would be represent as the disjoint union

H = H1 U H2 U.....U H13

P(H) = 13 ÷ 52

Answer:

y = -4

Step-by-step explanation:

3y - 2(5y - 7) = -9y + 6 (Given)

3y - 10y + 14 = -9y + 6 (Distribute)

-7y + 14 = -9y + 6 (Add like terms)

2y + 14 = 6 (Add 9y on both sides)

2y = -8 (Subtract 14 on both sides)

y = -4 (Divide 2 on both sides)

You can check by substituting the solution for y:

3(-4) - 2(5(-4) - 7) = -9(-4) + 6

-12 - 2(-20 - 7) = 36 + 6

-12 - 2(-27) = 42

-12 + 54 = 42

42 = 42

Answer:

(-2,8)

Step-by-step explanation:

To solve by substitution, first isolate a variable in one of the equations. Then, substitute the value of the variable from that equation into the other equation, giving either the x or y value of the solution. Finally, substitute that answer back into one of the two equations, finding the other missing value.

1) For both of the equations, the variable y has already been solved for. So, we can choose to substitute whatever y equals in one equation for the y in the other equation. Any choice is fine - I chose to substitute -4x for the y in y = 3x + 14.

[tex](-4x) = 3x + 14\\-7x = 14\\x = -2[/tex]

2) Now that x has been solved for, substitute the value for the x in one of the equations. Any choice is fine here, too - I chose to substitute -2 in y = -4x:

[tex]y = -4(-2) \\y = 8[/tex]

3) Both the x and y value of the solution has been solved for. x = -2 and y = 8. Therefore, the solution is (-2,8).

Answer:

40%

Step-by-step explanation:

Move the period over twice then place the percentage sign where you moved the period to

Answer:

40%

multiply both numerator and denominator by 100. You do this to find a equivalent fraction having 100 as the denominator. The fraction is 40 over 100, 100 represents the whole thing 40 is the part so it's basically part over whole. 40% is your answer. I'm sorry if my explanation made no sense
