Answer: A. 4/3 x

Step-by-step explanation:

x miles in 90 minutes to ? miles in 120 minutes

90 miles to 120 miles is 1.3333 which is equal to 4/3.

Multiply it to x and you have A. 4/3x

Answer:

A

Step-by-step explanation:

40% = 40/100 = 4/10 = 2/5

2/5 * 2/5 = 4/25 = 0.16

If A = 21 bh, b= 16, and A= 40, then value of h is 0.1190.

∴ A= 21 bh, b = 16, A= 40

Putting the values in A = 21 bh, we get

A= 21 bh

⇒ 40 = 21×16×h

⇒h = 40/21×16

⇒h = 0.1190

So the value of h is 0.1190.

Multiply the second equation by 3

Answer:

 D. Multiply the second equation by 3. The solution is x = 12, y = 10.

Step-by-step explanation:

You want the multiplier for the elimination of the y-variable in the system of equations x +3y = 42; 2x -y = 14.

The coefficients of y are +3 and -1, so multiplying the second equation by 3 will make it the opposite of the former. Then their sum is zero, which is what you want when eliminating the y-variable.

Multiplying the second equation by 3 and adding the first gives ...

  3(2x -y) +(x +3y) = 3(14) +(42)

  7x = 84 . . . . . . . . . simplify. Note the y-variable has been eliminated.

  x = 12 . . . . . . . . . divide by 7

  2(12) -y = 14 . . . . substitute for x in the second equation

  24 -14 = y = 10 . . . . add y-14

The solution is (x, y) = (12, 10).

Inequality which shows the number of phone calls in order to make Plan 1 more economical is, x> 375.

It means if customer calls for more than 375 times Plan 1 is more economical for him/her.

Given that Plan 1 offers unlimited calls against $29 per month.

and Plan 2 offers each call against $0.04 and with an adiditional charge $14 per month.

Let if there are x calls in a month then Plan 1 is more economical.

Plan 1 is more economical means Plan 1 costs the customer less than the Plan 2.

So for x calls the bill according to Plan 2 = 14 +0.04x

And the charge $29 fixed for Plan 1.

So the required inequality is,

14+0.04x > 29

Solving the inequality we get,

0.04x > 15

.x > 375

So the calls should be more than 375.

The slope of the line in the graph is -3/4

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane. Calculating the slope of a line is similar to finding the slope between two different points. In general, to find the slope of a line, we need to have the values of any two different coordinates on the line.

Taking two points from the line;

The slope of a line is given as

Answer:

  C.  all real numbers

Step-by-step explanation:

You want the domain of the function F(x) = 1.

The domain of a function is the set of values of the independent variable for which the function is defined. The function F(x) is defined for all possible values of x, so its domain is all real numbers.

Answer:

Step-by-step explanation:

(4i)·(-8i)·(5+5i) = 160+ 160i

We take into account that (i)²  = -1

1)

(4i)·(-8i) = (-32)·i² = (-32)·(-1) = 32

2)

32·(5 + 5i) = 32·5 + 32·(5i)  = 160 + 160 i

The solution for f(3) in the function when the function f(x) = 0.75(10 - x) + 1 is 6.25

From the question, we have the following equation that can be used in our computation:

f(x) = 0.75(10-x)+1

To make the equation legible, we need to rewrite it

So, we have the following representation

f(x) = 0.75(10 - x) + 1

Also from the question, we have

f(3)

This means that the value of x is 3, and we calculate f(x) when x = 3

Substitute the known values in the above equation, so, we have the following representation

f(3) = 0.75(10 - x) + 1

So, we have the following equation

f(3) = 0.75(10 - 3) + 1

There are constants to add or subtract to both sides of the equation

Also, there are factors to multiply or divide from both sides of the equation

So, we have the following representation

f(3) = 0.75 * 7 + 1

Solving further, we have

f(3) = 5.25 + 1

Evaluate the sum

f(3) = 6.25

Hence, the solution is 6.25

The equation of linear function is y=x-1.

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.

The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.

The given values are

x=1, y=0

x=2, y=1

x=3, y=2

x=4, y=3

The table represents that for the value of x the value of y is x-1,

Since for any two points from the table, let (1,0) and (2,1)

The slope = 2-1/1-0 = 1

And the interception of y is 0 when x=1

Therefore, the equation of the function can be written as,

y=x-1

A probability distribution that is symmetric about the mean is the normal distribution, also referred to as the Gaussian distribution. It demonstrates that data that are close to the mean occur more frequently than data that are far from the mean. The normal distribution appears as a "bell curve" on a graph. Data are symmetrically distributed and skew-free in a normal distribution. As one moves away from the center, values start to taper off and the majority of values are concentrated in this area. In a normal distribution, the mean, mode, and median are identical measures of central tendency.

Answer:

64 milliliters of 25% juice

96 milliliters of 50% juice.

Step-by-step explanation:

Answer:

96 mL of the 50% juice

64 mL of the 25% juice

Step-by-step explanation:

Declaration

Let the number of mL of 25% juice = x

Let the number of mL of 50% juice = y

Equations

25/100 * x + 50/100 y = 40/100 * 160        Combine

x + y = 160 mL

Solution

0.25x + 0.5y = 0.4 * 160

0.25x +0.5y = 64                            Multiply this equation by 4

0.25*4x + 0.5*4y = 64*4                Combine

x + 2y = 256                                   Put the first equation underneath and subtract

x + 2y = 256

x + y = 160                                    Subtract

     y = 96                                       mL of 50% fruit juice

x + y = 160

x + 96 = 160                                    Subtract 96 from both sides.

x + 96 - 96 = 160-96

x = 64                                              mL of the 25% fruit juice.

We list the operations done between two functions below:

In this problem we find three functions, two of them defined by quadratic equations (f(x), g(x)) and the other defined by a linear equation (h(x)). There are five operations that can be used b two functions:

Now we proceed to determine the result of each operation:

Case 1:

g(x) / h(x) = (4 · x² + 2 · x - 1) / (2 · x - 3)

Case 2:

h(x) - g(x) = (2 · x - 3) - (4 · x² + 2 · x - 1)

h(x) - g(x) = - 4 · x² - 2

Case 3:

h(f (x)) = 2 · (3 · x² + 2) - 3

h(f (x)) = 6 · x² + 1

Case 4:

f(x) + g(x) = (3 · x² + 2) + (4 · x² + 2 · x - 1)

f(x) + g(x) = 7 · x² + 2 · x + 1

Case 5:

h(f(x)) = 6 · x² + 1

h(f(2)) = 6 · 2² + 1

h(f(2)) = 25

Case 6:

f(h(x)) = 3 · (2 · x - 3)² + 2

f(h(x)) = 3 · (4 · x² - 12 · x + 9) + 2

f(h(x)) = 12 · x² - 36 · x + 29

f(h(3)) = 12 · 3² - 36 · 3 + 29

f(h(3)) = 29

Case 7:

g(x) + h(x) = (4 · x² - 12 · x + 9) + (2 · x - 3)

g(x) + h(x) = 4 · x² - 10 · x + 6

g(2) + h(2) = 4 · 2² - 10 · 2 + 6

g(2) + h(2) = 2

Case 8:

2 · f(x) - g(x) = 2 · (3 · x² + 2) - (4 · x² + 2 · x - 1)

2 · f(0) - g(2) = 2 · (3 · 0² + 2) - (4 · 2² + 2 · 2 - 1)
