Answer:

147.92

Step-by-step explanation:

Let the monthly salary be x

He saves 12 % and that is 17.75

x* 12% = 17.75

Change to decimal form

x *.12 = 17.17

Divide each side by .12

x*.12 /.12 = 17.75/.12

x =147.91666666

Rounding to the nearest cent

x = 147.92

Answer:

x = 1°

Step-by-step explanation:

Bisection means splitting the angle in to 2

So that means 4x-1 = 2x+1

4x-1 = 2x +1

4x = 2x + 2

2x = 2

x = 1°

Slope of the line :

[tex] \large\boxed{ \mathrm{ \frac{y_2 - y_1 }{x_2 - x_1} }}[/tex]

therefore, m = slope = -1

The equation of the line will be :

Now, let's plug the value of x and y from coordinates of second point,

Hence, the required values are :

The slope of line passing through  (-2, 7) and (3, 2). is -1 and the value of the y-intercept b is 5.

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.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

A line passes through (-2, 7) and (3, 2). We need to find the slope.

x₁=-2, x₂=3, y₁=7, y₂=2

substitute the values in formula of slope

m=2-7/3-(-2)

m=-5/5=-1

The slope intercept form of line is y=-x+b

To find b put the values of (-2,7)

7=-(-2)+b

7=2+b

7-2=b

5=b

y intercept is 5

Hence the slope of line passing through  (-2, 7) and (3, 2). is -1 and the value of the y-intercept b is 5.

Answer:

The slope is 5/8

Step-by-step explanation:

-5x+8y = 30

Add 5x to each side

8y = 5x+30

Divide by 8

8y/8 = 5/8x+30/8

y = 5/8x + 15/4

This is in slope intercept form y = mx+b where m is the slope and b is the y intercept

The slope is 5/8

Answer: 5/8

Step-by-step explanation:

You would first need to put the equation into standard form. so you add 5x on both sides

Then you divide 8 on both sides

that would give you y=5/8x+3.75

The slope is 5/8

Answer:

The right answer is "3.33333".

Step-by-step explanation:

The given points in the question are:

[tex]P=(7,-3) = (x_1,y_1)[/tex]

[tex]Q=(x,\frac{3}{6-x} )=(x_2,y_2)[/tex]

Now,

The slope of PQ will be:

= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

By putting the values, we get

= [tex]\frac{\frac{3}{6-x}+3 }{x-7}[/tex]

= [tex]\frac{3+18-3x}{(6-x)(x-7)}[/tex]

= [tex]\frac{21-3x}{(6-x)(x-7)}[/tex]

= [tex]\frac{3(x-7)}{(6-x)(x-7)}[/tex]

= [tex]\frac{3}{x-6}[/tex]

hence,

x = 6.9

it's slope will be:

6.3% of the remaining contaminants are removed from water samples after each round of filters

Step-by-step explanation:

I got a good feeling

The value of b indicates 14.9% of the contaminants remains in water after each round of filters.

Exponential regression refers to the process of arriving at an equation for the exponential curve that best fits a set of data.

[tex]y =a b^{x}[/tex] is the general form of the exponential regression equation.

Let the exponential regression equation be [tex]y = ab^{x}[/tex].

Taking natural logarithm both the sides of [tex]y = ab^{x}[/tex]

⇒ [tex]ln y = a + x ln b..(i)[/tex]

For the value of a and b substitute the value of y and x from the given table.

substitute, y = 100 and x = 0 in equation (i)

⇒ [tex]ln100= a + 0[/tex]

⇒ a = 4.6

Substitute, y = 15, x = 1 and a = 4.6 in equation (i)

⇒ [tex]ln15 = 4.6 +( 1)lnb[/tex]

⇒[tex]2.7 - 4.6 = lnb[/tex]

⇒[tex]lnb = -1.9[/tex]

⇒ b = [tex]e^{-1.9}[/tex]

⇒ b = 0.149

⇒b = 14.9%

Hence, the value of b indicates 14.9% of the contaminants remains in water after each round of filters.

Answer:

0.84 and 84

Step-by-step explanation:

1.05 (x -0.2x) = 1.05 (1-0.2)x = 1.05 * 0.8 x= 0.84x

84% of the original price of item

Answers:

=================================================

Explanation:

Think of x - 0.2x as 1x-0.2x. The numbers out front, the 1 and -0.2, combine to 0.8

The 0.8 converts to 80%, meaning that if there's a 20% off sale, then you still have to pay the remaining 80% of the original price.

The 1.05 indicates that we started with 100%, and then add on 5% sales tax, so 100% + 5% = 1 + 0.05 = 1.05

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

Simplifying the expression given to us leads to

1.05(x - 0.2x)

1.05(1x - 0.2x)

1.05(0.8x)

(1.05*0.8)x

0.84x

This shows that the final price, after tax, is 84% of the original price.

Using it's concept, it is found that there is a 0.6 = 60% probability that a student who does not have a cell phone is from grade 11.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Researching the problem on the internet, it is found that there are 30 students with no cell phones, and of those, 18 are in grade 11, hence the probability is given by:

p = 18/30 = 0.6.

0.6 = 60% probability that a student who does not have a cell phone is from grade 11.
