Answer 2

Answer:

h = 2

Step-by-step explanation:

Jenny collected donations at a pet store for the local animal shelter. As she left, Jenny
estimated she had collected $85. After counting the donations, she learned she had actually
collected $110. What is the percent error for her estimate?
If necessary, round your answer to the nearest tenth of a percent.

Answers

Answer:

Step-by-step explanation

Initial amount = $85

Final amount = $110

percentage error = ((Final amount - Initial amount)*100)/Final amount

= (25*100)/110

=22.7272

=22.7 (to the nearest tenth of a percent, which is 1 decimal place)

The solution is 22.7 %

The percentage error in the estimation of donations at the pet store by Jenny is 22.7 %

What is Percentage Error?

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage error is the difference between the measured value and the true value , as a percentage of the true value

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100

Given data ,

Let the percentage error be represented as A

Now , the value of A is

The estimated donation amount by Jenny = $ 85

The actual donation amount collected by Jenny = $ 110

Now , the percentage error in the estimation of Jenny A is calculated by the equation ,

Percentage error in the estimation of Jenny A = ( ( | estimated donation amount - actual donation amount collected by Jenny ) | / actual donation amount collected by Jenny ) ) x 100

Substituting the values in the equation , we get

Percentage error in the estimation of Jenny A = ( | 85 - 110 | / 110 ) x 100

On simplifying the equation , we get

Percentage error in the estimation of Jenny A = ( 25/110 ) x 100

Percentage error in the estimation of Jenny A = 2500 / 110

Percentage error in the estimation of Jenny A = 22.72 %

Therefore , the value of A is 22.7 %

Hence , the percentage error in the estimation is 22.7 %

ILL GIVE BRAINLY AND 10 PONITS Which inequality matches the graph?

Answers

Answer: not 100% but i think its A

Step-by-step explanation:

City A and City B had two different temperatures on a particular day. On that day, five times the temperature of City A was 8° C more than three times the temperature of City B. The temperature of City A minus twice the temperature of City B was −4° C. The following system of equations models this scenario: 5x = 8 + 3y x − 2y = −4 What was the temperature of City A and City B on that day? City A was 1° C, and City B was −1° C. City A was 4° C, and City B was 4° C. City A was 7° C, and City B was 9° C. City A was 10° C, and City B was 14° C.

Answers

The temperature of City A and City B on that day was 4° C respectively.

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

WE have been given system of equations as;

5x = 8 + 3y

x − 2y = −4

Now we can multiply equation B by -5 to eliminate the x variable in both equations.

Add them together;

5x = 8 + 3y

-5x + 10y = 20

Then add both of them A + B:

-5x + 10y + 5x - 3y = 20 + 8

7y = 28

y = 4

To solve for x;

5x = 8 + 3y

5(x) = 8 + 3(4)

x = 4

Hence, the temperature of City A and City B on that day was 4° C respectively.

x is rounded to 1 decimal place is 3.7
Write down the error interval for x.

Answers

The error interval for x will be 3.65<x<3.75 rounded to 1 decimal place.

What is interval notation?

It is defined as the representation of a set of values that satisfy a relation or a function. It can be represented as open brackets and close brackets the close brackets mean the value at the close bracket is also included, and the open bracket means the value at the open bracket does not include.

It is given that, the number is 3.7.

We have to find the error interval for x rounded to 1 decimal place for the number 3.7.

Thus, the error interval for x will be 3.65<x<3.75 rounded to 1 decimal place.

When a number has been rounded or truncated, error intervals are the upper bounds of accuracy. They represent the range of values that a number might have had before being rounded or truncated.

This is so that we may round the range of 3.65 to 3.75 to one decimal place, and as 3.74 or less is considered to be below 3.75, rounding to one decimal place gives us 3.7.

Thus, the error interval for x will be 3.65<x<3.75 rounded to 1 decimal place.

Answers

Answer:

The cost of the meal should be multiplied by 1.19.

---------------------------------------

Let the cost of the meal be x.

Adding a tip of 19%:

x + 19% = x + 0.19x = x (1 + 0.19) = 1.19x

Answer:

Wyatt should multiply with 1.19.

Step-by-step explanation:

Forming the expression,

→ 1 + (19% of 1)

Now the required number is,

→ 1 + (19% of 1)

→ 1 + ((19/100) × 1)

→ 1 + (19/100)

→ 1 + 0.19 = 1.19

Hence, required number is 1.19.

The maximum income is Maximum cost C is $19740

What is the maximum income?

Let Q represent the number of cars rented per day and P the rate.

To form the demand equation;

Q = a - bP

A car rental agency rents 440 cars per day at a rate of ​$40 per day

440 = a - 40b ......1

For each ​$1 increase in​ rate, 10 fewer cars are rented

(440-10) = a - (40+1)b

430 = a - 41b ......2

Subtracting equation 2 from 1

10 = b

From equation 1;

440 = a - 10(40)

a = 440 + 400 = 840

So;

Q = 840 - 10P

Cost C = Q×P = P (840-10P) = 840P - 10P^2

Maximum cost is at dC/dP = 0

dC/dP = 840 - 20P = 0

P = 840/20 = $42

Maximum cost C is

C = P(840-10P) = 42(840-370) = 42 × 470 = $19740

(9 × 100) + (5 × 10) + (4 × 1/100) + (8 × 1/1000)

900 + 50 + 4/100 + 8/1000

1040 + 1/25 + 1/125

118756/125

950.048

As per the requierd place values in the chart are:

Hundred: 9

Tens: 5

Ones: 0

Tenths: 0

Hundredths: 4

Thousandths: 8

Now, the number in standard form is 950.048.

Thus, the required place values in the chart are as Hundred: 9, Tens: 5, Ones: 0, Tenths: 0, Hundredths: 4, and Thousandths: 8. The number in standard form is 950.048.

Given g(x)=5x+4g(x)=5x+4, solve for xx when g(x)=9g(x)=9.

Answers

Answer:

[tex]\huge\boxed{\sf x = 1}[/tex]

Step-by-step explanation:

Given function:

g(x) = 5x + 4

Given that, g(x) = 9

So,

9 = 5x + 4

Subtract 4 to both sides

9 - 4 = 5x

5 = 5x

Divide 5 to both sides

1 = x

OR

x = 1

[tex]\rule[225]{225}{2}[/tex]

Answer:

x = 1

Step-by-step explanation:

The given information is,

→ g(x) = 5x + 4

→ g(x) = 9

Now the value of x will be,

→ 5x + 4 = g(x)

→ 5x + 4 = 9

→ 5x = 9 - 4

→ x = 5/5

→ [ x = 1 ]

Hence, the value of x is 1.

As per the concept of matrix multiplication, the value AB is [tex]\begin{bmatrix}11 &15 &-17 \\ -1&-4 &-4 \\ 17&15 &-22 \end{bmatrix}[/tex]

Matrix multiplication:

Matrix multiplication states that "The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix."

Given,

Here we have the matrix A and B.

And we have to perform the multiplication operation on it.

The value of matrix A is written as,

[tex]\begin{bmatrix} -4& 1 &-4 \\3 & 3 & 1 \\2 & 5 & 5\end{bmatrix}[/tex]

And the value of the matrix B is written as,

[tex]\begin{bmatrix} -4& -5 &4 \\3 & 3 & -5 \\2 & 2 & -1\end{bmatrix}[/tex]

Now, we have to multiply these two matrix, then we get the following,

[tex]\begin{bmatrix} -4& 1 &-4 \\3 & 3 & 1 \\2 & 5 & 5\end{bmatrix}\times\begin{bmatrix} -4& -5 &4 \\3 & 3 & -5 \\2 & 2 & -1\end{bmatrix}[/tex]

And the multiplication of the matrix is written as,

[tex]\begin{bmatrix} -4\times-4+1\times3-4\times2& -4\times-4+1\times3-4\times2 &-4\times4+1\times-5-4\times-1 \\3\times-4+3\times3+1\times2 & 3\times-5+3\times3+1\times2 & 3\times4+3\times-5+1\times-1 \\2\times-4+5\times3+5\times2 & 2\times-5+5\times3+5\times2 & 2\times4+5\times-5+5\times-1\end{bmatrix}[/tex]

When we simplify this one then we get the value of AB is,

[tex]\begin{bmatrix}11 &15 &-17 \\ -1&-4 &-4 \\ 17&15 &-22 \end{bmatrix}[/tex]

Use the distributive property to solve.
0.5(x+9)=32
Solve by dividing first
0.5(x+9)=32
Use the distributive property to solve.
2(x+12)=50
Solve by dividing first
2(x+12)=50

Answers

Answer:

x = 55

x = 13

Step-by-step explanation:

Use the distributive property to solve.

0.5(x+9)=32

0.5x + 4.5 = 32

0.5x = 27.5

x = 55

Solve by dividing first

0.5(x+9)=32

x + 9 = 32/0.5

x + 9 = 64

x = 55

Use the distributive property to solve.

2(x+12)=50

2x + 24 = 50

2x = 26

x = 13

Solve by dividing first

2(x+12)=50

x + 12 = 50/2

x  + 12 = 25

x = 13
