Answer:

Distance of ladder from base = 4.22 feet (Approx.)

Step-by-step explanation:

Given:

Length of ladder = 10 feet

Angle with ground = 65°

Find:

Distance of ladder from base

Computation:

Length of ladder (hypotenuse) = 10 feet

Distance of ladder from base (Base)

Using trigonometry function

Cosθ = Base / Hypotenuse

Cosθ = Distance of ladder from base / Length of ladder

Cos65 = Distance of ladder from base / 10

0.4226 = Distance of ladder from base / 10

Distance of ladder from base = 0.4226 x 10

Distance of ladder from base =  4.226

Distance of ladder from base = 4.22 feet (Approx.)

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:

$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:

8%

Step-by-step explanation:

We can solve this by making use of the simple interest formula

I= PRT/100

480= 3000×R×2/100

480= 6000R/100

Cross multiply

48000= 6000R

R= 48000/6000

= 8%

Hence the rate is 8%

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

Select Yes or No for each

To do this, we make use of Euler's formula

[tex]F + V - E = 2[/tex]

Where

[tex]F \to Faces; V \to Vertices; E \to Edges[/tex]

[tex](a):\ Faces = 8; Vertices = 12; Edges = 6[/tex]

Using: [tex]F + V - E = 2[/tex]

[tex]8 + 12 - 6 = 2[/tex]

[tex]14 = 2[/tex]

The above equality is false. Hence, (a) does not exist

[tex](b):\ Faces = 6; Vertices = 6; Edges = 4[/tex]

Using: [tex]F + V - E = 2[/tex]

[tex]6 + 6 - 4 = 2[/tex]

[tex]8 = 2[/tex]

The above equality is false. Hence, (b) does not exist

[tex](c):\ Faces = 20; Vertices = 30; Edges = 12[/tex]

Using: [tex]F + V - E = 2[/tex]

[tex]20 + 30 - 12 = 2[/tex]

[tex]38 = 2[/tex]

The above equality is false. Hence, (c) does not exist

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
