Answer: Option b

b. x greater or equal than 1.8

Step-by-step explanation:

In this problem we have the following inequality:

[tex]2x\leq 3(x-0.6)[/tex]

To solve it we must group the x on one side and the constants on the other side

[tex]2x\leq 3(x-0.6)[/tex]

Apply distributive property on the right side of the inequality

[tex]2x\leq 3x-3*0.6[/tex]

[tex]2x\leq 3x-1.8[/tex]

Subtract 3x on both sides of the inequality

[tex]2x-3x\leq 3x-3x-1.8[/tex]

[tex]-x\leq-1.8[/tex]

Multiply by -1 both sides of the inequality

[tex]x\geq 1.8[/tex]

The answer is the option b

Answer:

the answer is option B

Step-by-step explanation:

Answer:

A)

15 hours

B)

108 hours

C)

2074.29 miles

Step-by-step explanation:

Under the assumption the earth is a perfect circle, then in one complete rotation about its axis ( 24 hours) the Earth will cover 360 degrees or 2π radians.

A)

In every 24 hours the earth rotates through 360 degrees ( a complete rotation). We are required to determine the length of time it will take the Earth to rotate through 225 degrees. Let x be the duration it takes the earth to rotate through 225 degrees, then the following proportions hold;

(24/360) = (x/225)

solving for x;

x = (24/360) * 225 = 15 hours

B)

In 24 hours the earth rotates through an angle of 2π radians (a complete rotation) . We are required to determine the length of time it will take the Earth to rotate through 9π radians. Let x be the duration it takes the earth to rotate through 9π radians, then the following proportions hold;

(24/2π radians) = (x/9π radians)

Solving for x;

x = (24/2π radians)*9π radians = 108 hours

C)

If the diameter of the earth is 7920 miles, then in a day or 24 hours a point on the equator will rotate through a distance equal to the circumference of the Earth. Using the formula for the circumference of a circle;

circumference = 2*π*R = π*D

                         = 7920*3.142

                         = 24891.43 miles

Therefore a point on the equator covers a distance of 24891.43 miles in 24 hours. This will imply that the speed of the earth is approximately;

(24891.43miles)/(24 hours) = 1037.14 miles/hr

The distance covered by the point in 2 hours will thus be;

1037.14 * 2 = 2074.29 miles

Answer:

Shravan's age is 40 years old

Gaurav’s age is 30 years old

Step-by-step explanation:

Let

x-----> Shravan's age

y-----> Gaurav’s age

we know that

x=y+10 -----> equation A

(1/7)(x-5)=(1/5)(y-5) ----> equation B

substitute equation A in equation B and solve for y

(1/7)(y+10-5)=(1/5)(y-5)

(1/7)(y+5)=(1/5)(y-5)

5(y+5)=7(y-5)

5y+25=7y-35

7y-5y=25+35

2y=60

y=30 years

Find the value of x

x=y+10  ----> x=30+10=40 years

therefore

Shravan's age is 40 years old

Gaurav’s age is 30 years old

Answer: x÷(2÷5y)

Step-by-step explanation: this is because you have to first do the quotient of 2 and try then the answer will be divided by 5

Answer:

The quotient of x and the quotient of 2 and 5y.

Expression:

x/(2/5y)

Explanation:

The quotient means to divide the numbers. The “and” after quotient is what the number is dividing with. So, x us dividing with the division of 2 and 5y.

This result represents the total area under the curve y = x^2 + 4 between x = -3 and x = 2.

The area under the curve y = x^2 + 4 on the interval [-3,2] can be found using definite integration. The definite integral of a function gives us the net area between the function and the x-axis across the specified interval. To compute the area, we set up the integral from -3 to 2 of the function x^2 + 4.

To solve this, we integrate the function with respect to x:

This result represents the total area under the curve y = x^2 + 4 between x = -3 and x = 2.

ANSWER

B. 10

EXPLANATION

We need to find the value of x first.

It was given that the perimeter of triangle XYZ is 24.

This means that:

XY+YZ+XZ=24

we substitute the expression in terms of x to get;

[tex](5x - 1) + (13 - x) = 24[/tex]

This implies that

[tex]5x - x = 24 - 13 + 1[/tex]

[tex]4x = 12[/tex]

Divide both sides by 4 to get;

[tex]x = 3[/tex]

|WY|=|ZX|=13-3=10

Answer:

WY = 10 units

Step-by-step explanation:

From the figure we can see a rectangle WXYZ.

Diagonals of rectangle are equal.

It is given that, Perimeter of triangle XYZ = 24

XY + YZ = 5x - 1 and XZ = 13 - x

To find the value of x

Perimeter of ΔXYZ = XY + YZ + XZ

24 = 5x - 1 + 13 - x

4x + 12 = 24

4x = 12

x = 12/4 = 3

x = 3

To find the value of WY

We have WY = XZ

XZ = 13 - x

 = 13 - 3 = 10

Therefore WY = XZ = 10 units

Answer: It can not be a mixed number because if you divide -27 by 50 you get -0.54, so then if you turn -0.54 in fraction form it would be -27/50, so the fraction would stay the way it is. -27/50 is not an improper fraction. To be improper, the numerator must be greater than the denominator!

Hello There!

The value of the number "5" in the number 15,406 would be the value of 5,000

For this case we must find an expression equivalent to:

[tex](x ^ {\frac{1}{4}} * y ^ {16}) ^ {\frac {1} {2}}[/tex]

By definition of power properties we have to:

[tex](a ^ n) ^ m = a ^ {n * m}[/tex]

Then, rewriting the expression:

[tex](x ^ {\frac {1 * 1} {4 * 2}} * y ^ {\frac {16 * 1} {2}}) =\\x ^ {\frac {1} {8}} * y ^ {\frac {16} {2}}) =\\x ^ {\frac {1} {8}} * y ^ {8}[/tex]

Answer:

Option B

The conjugate of the complex number 2 - 8i is 2 + 8i, found by changing the sign of the imaginary part from negative to positive.

The conjugate of a complex number is found by changing the sign of the imaginary part.

For a complex number with a real part of 2 and an imaginary part of -8i, the complex number is represented as 2 - 8i. To find its conjugate, we change the sign of the imaginary part, resulting in 2 + 8i.

The general form of a complex number is a + bi, where a is the real part and bi is the imaginary part.

The conjugate is then written as a - bi. Therefore, if we have the complex number z = 2 - 8i, the conjugate, denoted as [tex]\( \overline{z} \)[/tex], is 2 + 8i.

Answer: The graph is attached.

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept.

You can solve for "y":

[tex]2y<5x-10\\\\y<\frac{5}{2}x-\frac{10}{2}\\\\y<\frac{5}{2}x-5[/tex]

You need to rewrite the expression:

[tex]y=\frac{5}{2}x-5[/tex]

You can identify that the slope of this line is:

[tex]m=\frac{5}{2}[/tex]

And the y-intercept is:

[tex]b=-5[/tex]

Substitute [tex]y=0[/tex] and solve for "x" to know the x-intercept:

[tex]0=\frac{5}{2}x-5\\\\5*2=5x\\\\x=2[/tex]

Now you know that the line passes through the points (0,-5) and (2,0).

Since the inequality is "<", you know that the line must be dashed and the shaded region must be below the line [tex]y=\frac{5}{2}x-5[/tex].

Knowing this, you can graph it (Observe the graph attached)

Answer:

13/6

Step-by-step explanation:

-6 1/3 + 5 5/6

1. You can reduce the first equation to 2

-6 1/3, becomes -2 x 1/1. This is because 3 goes into itself 1 time, and it goes into 6, -2 times. Your new equation: -2 + 5 5/6

2. Multiply the 5's in 5 5/6 by each other to get...

25/6

Your new equation: -2 + 25/6

3. Multiply 6 by -2 to get -12

4. Now add the numerators(remember -12 is basically, -12/1) together to get your answers

-12 + 25/6 = 13/6

Hello There!

If we add -6 1/3 and 5 5/6 together, we will get a sum of -1/2

STEP 1 First, I like to convert mixed numbers into improper fractions because they are easier to work with. So, I would change -6 1/3 to -19/3. Then, I would change 5 and 5/6 to 35/6.

STEP 2 Applying the fraction formula for addition. (-19x6) + (35x3) and then i would put this over 6x3

STEP 3   -114+105

                      18

STEP 4

-9/18 = -1/2

Step 1: Convert [tex]\frac{5\pi }{12}[/tex], which is in radians into degrees. To convert it multiply by [tex]\frac{180}{\pi }[/tex]

[tex]\frac{5\pi }{12} =\frac{180}{\pi }[/tex]

900/12

75

Step 2: 75 degrees isn't on the unit circle but 45 degrees and 30 degrees is. Since 45 + 30 = 75 you can use the cosine of 45 and 30 to find the exact value

cos45 = [tex]\frac{\sqrt{2} }{2}[/tex]

cos30 =[tex]\frac{\sqrt{3} }{2}[/tex]

Step 3: Add the cos45 and cos30 to get cos5pi/12

[tex]\frac{\sqrt{2} }{2} +\frac{\sqrt{3} }{2} = \frac{\sqrt{2}+\sqrt{3}}{2}[/tex]

Answer:

y = - 3x + 16

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x + 8 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, so

y = - 3x + c ← is the partial equation of the perpendicular line

To find c substitute (6, - 2) into the partial equation

- 2 = - 18 + c ⇒ c = - 2 + 18 = 16

y = - 3x + 16 ← equation of perpendicular line

We want to simplify the following exponential expressions

a.

[tex] {2}^{4} [/tex]

This implies that

[tex] {2}^{4} = 2 \times 2 \times 2 \times 2[/tex]

[tex] {2}^{4} = 16[/tex]

b. Any non-zero number exponent zero is 1.

This implies that,

[tex] {3}^{0} = 1[/tex]

c. The given exponentiial expression is,

[tex] {4}^{6} \times {4}^{ - 3} [/tex]

The bases are the same so we add the exponents.

[tex] {4}^{6} \times {4}^{ - 3} = {4}^{6 + - 3} [/tex]

This simplifies to,

[tex]{4}^{6} \times {4}^{ - 3} = {4}^{3} [/tex]

[tex]{4}^{6} \times {4}^{ - 3} = 4 \times 4 \times 4 = 64[/tex]

d. We want to simplify:

[tex] { ({2}^{3}) }^{2} [/tex]

This is the same as

[tex]{ ({2}^{3}) }{ ({2}^{3}) }[/tex]

We add the exponents now to get:

[tex]{2}^{3 + 3} = {2}^{6} = 64[/tex]

James will have $32,270.13 after 6 years

Answer:

[tex]y=20000(1.083)^6[/tex]

Step-by-step explanation:

Let y represents the amount James have after 6 years,

Given,

Principal amount, P = $ 20,000,

Compound rate of interest per year, r = 8.3 %,

Thus, the amount after x years would be,

[tex]A=P(1+\frac{r}{100})^x[/tex]

[tex]=20,000(1+\frac{8.3}{100})^x[/tex]

[tex]=20000(1.083)^x[/tex]

Therefore, the amount after 6 years would be,

[tex]y=20000(1.083)^6[/tex]

Which is the correct equation that represents the amount, James will have after 6 years.
