0.4(5x-12)+0.5x=15.2

We move all terms to the left:

0.4(5x-12)+0.5x-(15.2)=0

We add all the numbers together, and all the variables

0.5x+0.4(5x-12)-15.2=0

We multiply parentheses

0.5x+2x-4.8-15.2=0

We add all the numbers together, and all the variables

2.5x-20=0

We move all terms containing x to the left, all other terms to the right

2.5x=20

x=20/2.5

Answer:

3 2/3

Step-by-step explanation:

Answer: f(x) = 3/2 (8/7)-x

Step-by-step explanation:

Answer:

a)  6.

b)  0 (multiplicity 3), -5 (multiplicity 2) and 7/2.

c) and (d) - See below.

Step-by-step explanation:

(a)  f(x) = x^3(x + 5)^2 (2x - 7)

The highest degree of x  (= x^3*x^2*x) = 3+2+1 = 6.  

(b) The zeros are 0 ( from the x^3 = 0) multiplicity 3, from  x + 5 = 0 we have -5 (multiplicity 2) and from 2x - 7 =0, 7/2.

(C)  The graph just touches the x axis at (-5, 0) and pass through at (0,0) and (7/2, 0).

(d) The graph rises to the left for very large negative values of x and falls to the right at very large values of x.

At the extreme ends this graph resembles the graph of -x^3.

37.68in

Step-by-step explanation:

circumference = 2πr

r= radius = diameter/2 = 12/2 =6 in

C= 2πr = 2 x 3.14 x 6= 37.68in

In the equation √64 - 3 = 4, we first take the square root of 64 to get 8, then subtract 3 to get 5, NOT 4. Thus, the given equation is not accurate.

The model to represent the mathematical expression √64 - 3 = 4 is firstly taking the square root of 64 which gives 8, and then subtracting 3 from it to get 4. The complete equation is as follows:

Answer:

- 30.75 < x < - 29.25

Step-by-step explanation:

Inequalities of the type | x | < a , always have solutions of the form

- a < x < a

Given

| 0.2x + 6 | < 0.15, then

- 0.15 < 0.2x + 6 < 0.15 ( subtract 6 from all 3 intervals )

- 6.15 < 0.2x < - 5.85 ( divide all intervals by 0.2 )

- 30.75 < x < - 29.25

To solve the inequality |0.2x+6| < 0.15, we split it into two separate inequalities and find that the solution for x is -30.75 < x < -29.25.

To solve the inequality |0.2x+6| < 0.15, we first consider the absolute value function. This means we are looking for values of x that make 0.2x + 6 less than 0.15 and greater than -0.15. We split this into two separate inequalities:

Solving the first inequality for x:

0.2x < 0.15 - 6
0.2x < -5.85
x < -5.85 / 0.2
x < -29.25

Solving the second inequality for x:

0.2x > -0.15 - 6
0.2x > -6.15
x > -6.15 / 0.2
x > -30.75

Therefore, combining the two inequalities, we find the solution for x is:

-30.75 < x < -29.25.

Answer:

The height of the cup is 0.51 in.

The height of the cup is 4.59 in.

Step-by-step explanation:

The volume of the cylinder is [tex]\pi r^2 h[/tex]

Given that,

The volume of the cup is 14.4375 in³.

If the measuring cup has a radius of 3 in.

Then,

[tex]\pi r^2h=14.4375[/tex]

Plug r= 3 in.

[tex]\pi (3)^2h=14.4375[/tex]

[tex]\Rightarrow h=\frac{14.475}{9\pi }[/tex]

⇒h=0.51 in.

The height of the cup is 0.51 in.

If it has radius of 1 in.

Then,

[tex]\pi r^2h=14.4375[/tex]

Plug r= 1 in.

[tex]\pi (1)^2h=14.4375[/tex]

[tex]\Rightarrow h=\frac{14.475}{1\pi }[/tex]

⇒h=4.59 in.

The height of the cup is 4.59 in.

Answer:

4*100+.9*0.1+.002*.001

Step-by-step explanation:

The student's question is unclear and lacks clarity. It is recommended that they provide more information or context so that an accurate explanation can be given.

The question seems to be unclear. As a tutor, I would ask the student to clarify their question more specifically. The number '400.902' is indeed an expression, however, it's not clear what it's supposed to be equivalent to. Understanding the context can help provide a more accurate answer, as '400.902' could represent a multitude of things, such as a decimal, a fraction, a percentage or even part of a scientific notation. Without this information, I can't provide a reliable explanation or comparison.

Answer: The center is 0,4

Step-by-step explanation:

Use this form to determine the center and radius of the circle:

(

x-h)^2+(y-k)^2=r^2

Match the values in this circle to those of the standard form. The variable  r  represents the radius of the circle,  h  represents the x-offset from the origin, and  k  represents the y-offset from origin:

r=8

h=0

k=4

The center of the cirle is found at (h,k): (0,4)

The radius is 8

The oblique prism below has an isosceles right triangle base. An oblique right triangular prism is shown. The triangular bases have 2 sides with a length of x. The length of they hypotenuse is unknown. The distance from the 2 triangular bases is (x + 3). The vertical height of the prism is (x + 2). What expression represents the volume of the prism, in cubic units?

One-halfx3 + x2

One-halfx3 + Three-halves x2

x3 + x2

x3 + 3x2

My answer:

Given that:

The oblique prism below has an isosceles right triangle base and the length of the base is x

=> the area of the base: 1/2 *x*x = 1/2[tex]x^{2}[/tex]

The vertical height of the prism is (x + 2)

=> The volume of the oblique prism is:

V = the base area * the vertical height

<=> V = 1/2[tex]x^{2}[/tex] (x + 2)

<=> V = [tex]1/2 x^{3}[/tex] + [tex]x^{2}[/tex]

Final answer:

To calculate total gross pay, sum the hourly wage and tips earned. This sum represents the entire earnings before any deductions such as tax or social security are taken into account. Thus, option b is correct.

Explanation:

When calculating total gross pay, you should use your hourly wage and tips. The gross pay represents the total amount earned before any deductions, such as taxes or social security, are subtracted. To find the total gross pay, simply add the total amount of earned hourly wage to the amount received from tips.

For instance, if an employee receives $15 per hour and works for 8 hours and also earns $40 in tips, their gross pay for that day would be:

Hourly wage: $15/hour x 8 hours = $120

Tips: $40

So, the total gross pay would be $120 + $40 = $160 for that day.

So, option b is correct.

Answer:

  A.  It is 8 below the mean

Step-by-step explanation:

The sum of differences from the mean is always zero. If x is the difference from the mean that the fourth data value has, then we must have ...

  3 + 4 + 1 + x = 0

  x = -8 . . . . . . . . . subtract 8

The fourth data value must be 8 below the mean.

Additional comment

I find this property of the mean to be very useful in solving any number of problems related to differences from an actual or a desired mean.

Given:

Given that the side AB is parallel to side DE.

The length of AB is 15 feet.

The length of BC is 9 feet.

The length of CD is 6 feet.

The length of DE is x feet.

We need to determine the proportion that solves the distance between D and E.

Proportion:

The proportion that solves the distance between D and E can be determined by the similar triangle property.

Thus, we have;

[tex]\frac{BC}{CD}=\frac{AB}{DE}[/tex]

Substituting the values, we have;

[tex]\frac{9}{6}=\frac{15}{x}[/tex]

Thus, the proportion that solves the distance between D and E is [tex]\frac{9}{6}=\frac{15}{x}[/tex]
