What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Using the rule of BODMAS the solution for the expression  39 ÷ (2 + 1) - 2 × (4 + 1) is,

39 ÷ (2 + 1) - 2 × (4 + 1)

=  39 ÷ (3) - 2 × (5)

= 13 - 2  × (5)

= 13 - 10

= 3

Hence, the solution for the expression  39 ÷ (2 + 1) - 2 × (4 + 1) is 3.

2A-hb/h=a

Multiply by 2 on both sides to get:
2A = h(a + b)

Divide by h on both sides to get:
2A/h = a + b

Subtract b from both sides to get:
(2A/h) - b = a

Answers

Answer:

Option (2)

Step-by-step explanation:

A function 'f' has been given as,

f(x) = 3x + 1

And the inverse of this function is,

[tex]f^{-1}(x)=\frac{x-1}{3}[/tex]

We have to find the value of f(2).

So we will use the expression: f(x) = 3x + 1

By substituting x = 2 in this function,

f(2) = 3×2 + 1

     = 6 + 1

     = 7

This result tells us the value of the function at x = 2.

Therefore, Option (2) will be the answer.

<3 = 47

<4 = 133

<5 = 47

<6 = 133

<7 = 47

<8 = 133

Step-by-step explanation:

im assuming a transversal is cutting the two lines, and that the 2 lines are parallel

2 = u must do 180-47 since theyre supplementary angles

3 = they are vertical angles

4 = 4 is a vertical angle to 2, but you can also do 180-47 since it is supp. to 3

5 = corresponding angle to the 47 degrees one

6 = alternate interior with 4, but also corresponding with 2

7 = vertical angles with 5 but also alternate exterior with the 47 degree angle , but also supplementary with both 6 and 8, and corresponding with 3

8= corresponding with 4, but also supplementary to 7 and 5. and vertical to 6

Answer:

<2= 133  <3 = 47   <4 = 133  <5 = 47  <6 = 133  <7 = 47  <8 = 133

Sammie bought____feet of fencing.

Answers

Answer:

3.5 feet

Step-by-step explanation:

The question isn't formatted properly.

We have:

(x + 6) feet on each side of the square

(3x + 6) feet horizontally on the rectangle

(x - 1) feet vertically on the rectangular

First, we need to determine the perimeter of the square:

[tex]Perimeter = 4 * Length[/tex]

[tex]Perimeter = 4 * (x + 6)[/tex]

[tex]Perimeter = 4x + 24[/tex]

Next, we determine the perimeter of the rectangle

[tex]Perimeter = 2(Length + Width)[/tex]

[tex]Perimeter = 2(3x + 6 + x - 1)[/tex]

[tex]Perimeter = 2(3x + x+ 6 - 1)[/tex]

[tex]Perimeter = 2(4x+ 5)[/tex]

[tex]Perimeter = 8x+ 10[/tex]

Equate both perimeters:

[tex]8x + 10 = 4x + 24[/tex]

Collect Like Terms

[tex]8x - 4x = 24 - 10[/tex]

[tex]4x = 14[/tex]

Solve for x

[tex]x = 14/4[/tex]

[tex]x = 3.5[/tex]

what is the best estimate of 45 percent of 76

Answers

9514 1404 393

Answer:

In order of improvement:

383434.2 (actual value)

Step-by-step explanation:

In my engineering experience, a method of estimating should satisfy two requirements:

it should be relatively easy to accomplish mentallyit should provide a means of estimating the error in the estimate

__

Multiplication and division by 2 are generally easy to perform mentally.

We note that 45% is about 50%.

  50% of 76 is 76/2 = 38 . . . a good starting estimate

45% is down 5% from 50%, so the actual value will be 5/50 = 10% lower than this first estimate

A good second estimate is 38 -0.10(40) = 34.

A better estimate is 38 -3.8 = 34.2, which is the actual value of the expression.

_____

Alternate approach

You could also transform the problem to 76% of 45, which is about 3/4 of 44, or about 33. Figuring the error adjustment on this approach is somewhat more difficult, as it is factors of 1/75 and 1/44 too low. 1 part in 44 is not too difficult to figure, as it is 33/44 = 3/4, so a better estimate is 33.75. It takes a calculator to figure 1 part in 75 of this, which is 0.45. Adding that amount gets you to the actual value of 34.2.

The body mass index (BMI) of a person is the person’s weight divided by the square of his or her height. It is an indirect measure of the person’s body fat and an indicator of obesity. Results from surveys conducted by the Centers for Disease Control and Prevention (CDC) showed that the estimated mean BMI for US adults increased from 25.0 in the 1960–1962 period to 28.1 in the 1999–2002 period.

Suppose you are a health researcher. You conduct a hypothesis test to determine whether the mean BMI of US adults in the current year is lower than the mean BMI of US adults in 2000. Assume that the mean BMI of US adults in 2000 was 28.1 (the population mean). You obtain a sample of BMI measurements of 1,034 US adults, which yields a sample mean of M = 28.9. Let μ denote the mean BMI of US adults in the current year.

Formulate your null and alternative hypotheses by selecting the appropriate values in the blue dropdown menus that follow.

Answers

Answer:

The null hypothesis is  [tex]H_o : \mu = 28.1[/tex]

 The alternative hypothesis is  [tex]H_a : \mu < 28.1[/tex]

Step-by-step explanation:

From the question we are told that

   The population mean at 1960 - 1962 is  [tex]\mu_1 = 25.0[/tex]

    The population mean at 1999- 2002 is  [tex]\mu_2 = 28.1[/tex]

     The sample size is  n=  1034

     The sample mean is  [tex]M = 28.9[/tex]

 The null hypothesis is  [tex]H_o : \mu = 28.1[/tex]

 The alternative hypothesis is  [tex]H_a : \mu < 28.1[/tex]

Describe and correct the error a student made when graphing the linear equation y = -3/4x -6

Answers

Answer:

In step 1 the y-intercept should be plotted at (0,-6)

Step-by-step explanation:

Remember that to find the Y intercept in any linear equation you need to use 0 as your X value, this means taking the formula in the y=mx+b form and replacing X with a 0.

Since the formula is y = -3/4x -6

We just insert a 0 insted of the "x"

y = -3/4(0) -6

y=0-6

y=6

So the y-intercept sould be placed in (0,-6)

That's what he did wrong when graphing the equation.

The price of a sweater was reduced from $20 to $12, By what percentage was the price of the sweater reduced?

Answers

Answer:

40%

Step-by-step explanation:

12 ÷ 20 = .6

You can convert the .6 to a percentage by multiplying it:

.6 x 100 = 60%

If 12 is 60% of 20, then that means 40% was taken away.

 Price of the sweater was reduced by 40%.

   Given in the question,

Original Price of a sweater is $20.Price of the sweater was reduced from $20 to $12.

Percentage reduction in the price from $20 to $12 can be calculated from the expression,

Percentage reduction = [tex]\frac{\text{Change in price}}{\text{Original price}}\times 100[/tex]

                                     = [tex](\frac{20-12}{12})\times 100[/tex]

                                     = [tex]\frac{8}{12}\times 100[/tex]

                                     = 40%

     Therefore, price of the sweater was reduced by 40%.

Answer:

No; the domain values are not at regular intervals.

The correct option is b.

What is an exponential function?

Mathematical functions with exponents include exponential functions. f(x) = bˣ, where b > 0 and b 1, is a fundamental exponential function.

In an exponential function, the domain values are usually at regular intervals, and the range values have a common factor or a common sum.

In the given data, the domain values are not at regular intervals.

The difference between 3 and 1 is 2, and the difference between 1 and -1 is 2, but the difference between -1 and -3 is -2.

This indicates that the domain values are not at regular intervals, which means that the data cannot be modeled by an exponential function.

Additionally, the range values also do not have a common factor or a common sum. The difference between consecutive y-values is 1, which is not a constant factor or sum.

Therefore, the data cannot be modeled by an exponential function.
