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

Answer:

$765

Step-by-step explanation:

Given data

Principal= $750

Rate= 2%

Time= 1 year

The simple interest expression is given as

A=P(1+rt)

substitute

A= 750(1+0.02*1)

A= 750(1.02)

A= $765

Hence the final amount is $765

Answer: 1/12

Step-by-step explanation:

First make all the fractions have the same denominator. To do that, multiply the fractions by a number that will get them the same denominator. In this case, multiply 1/4 by 3, and 2/3 by 4.

1/4 x 3/3 = 3/12

2/3 x 4/4 = 8/12

then you have 3/12 + 8/12 = 11/12

so, blue is 1/12

Answer:

1/12 of the pins are blue

Step-by-step explanation:

¼ yellow & ⅔ red

First you have to find a common denominator.

4×3 =12 & 3×4 =12 so the common denominator is 12.

Now × the numerator on the fraction with the same number that you x the denominator and you will get 3/12 and 8/12.

3/12 +8/12 = 11/12

12/12 - 11/12 = 1/12

Therefor 1/12 of the pins are blue

Answer:

Step-by-step explanation:

Because they are vertically opposite angles

Answer:

Step-by-step explanation:

Both angles are opposite of each other, therefore, x = 114

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:

Student C

Step-by-step explanation:

The fraction ends up being 3 and you get 3* 3^-1 so you add 1 to the exponent.

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

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.
