Answer:

20/40

Step-by-step explanation:

If you make them decimals, then 17/40 = .43

0/40= .00    20/40 = .50    40/40 =1.00

so .50 is closest to .43.

Let Carlo's age =  x

Equation: 6*x = 108

               6x = 108

Solution:

6x = 108

x = 108/6

x = 18

Carlo's age = 18 years

Answer:

Let the age of Carlo be x

Answer:

r=ln3/10

Step-by-step explanation:

The daily rate is given by 3 to the power x divided by 10.

We have given that a sample of bacteria is growing at a continuously compounding rate.

The sample triples in 10 days.

The daily rate of the bacteria growth is. exponential growth is in the form

y = abˣ

where y, x are variables.

a is the initial value

Sample triples, in 10 days. therefore the value of b=3.

Therefore we get,

[tex]y=3a^{\frac{x}{10}[/tex]

[tex]y=a3^{\frac{x}{10}[/tex]

Therefore the daily rate is given by [tex]3^{\frac{x}{10}[/tex].

Answer:

[tex]\sin(C)=\pm\sqrt{1-\cos^2(C)}[/tex]

Step-by-step explanation:

Given the Pythagorean Identity:

[tex]\sin^2(C)+\cos^2(C)=1\\[/tex]

We want to solve for sin(C).

First, we will subtract cos²(C) from both sides:

[tex]\sin^2(C)=1-\cos^2(C)[/tex]

Next, we will take the square root of both sides. Since we are taking an even-root, we will need to add plus/minus. Hence:

[tex]\sin(C)=\pm\sqrt{1-\cos^2(C)}[/tex]

Answer:

B

Step-by-step explanation:

They are similar by the definition of similarity in terms of a dilation.

Two figures must have congruent (equal) comparable angle measures and proportional sides in order to be considered similar. Dilations produce comparable numbers because adding the scale factor produces proportional sides while keeping the angle measurement and form constant.

Given

In GHI ,

GH = 3cm [using distance formula]

HI = 5.65 cm

GI = 6 c

In JKL,

JK = 2.2361 cm

KL = 2.8284 cm

Answer:

Step-by-step explanation:

1). 10 = [tex]\frac{1+7x}{7+x}[/tex]

   10(7 + x) = 1 + 7x

   70 + 10x = 7x + 1

   10x - 7x = 1 - 70

   3x = -69

   x = -23

2). 0.2 = [tex]\frac{6+2x}{12+x}[/tex]

    0.2(12 + x) = 6 + 2x

    2.4 + 0.2x = 6 + 2x

    2.4 - 6 = 2x - 0.2x

    1.8x = -3.6

    x = -2

3). 0.8 = [tex]\frac{x}{x+0.5}[/tex]

    0.8(x + 0.5) = x

    0.8x + 0.4 = x

    x - 0.8x = 0.4

    0.2x = 0.4

    x = 2

4). 3.5 = [tex]\frac{4+2x}{0.5-x}[/tex]

    3.5(0.5 - x) = 4 + 2x

    1.75 - 3.5x = 4 + 2x

    -3.5x - 2x = 4 - 1.75

    -5.5x = 2.25

     x = -[tex]\frac{2.25}{5.5}[/tex]

     x = - [tex]\frac{9}{22}[/tex]

To calculate this percentage, we suggest using this formula:

% / 100 = Part / Total

Substituting the provided values:

60/100 = Part / 20

Performing cross multiplication:

60 x 20 = 100 x Part, or

1200 = 100 x Part

Now just divide by 100 and get the answer:

Part = 1200/100 = 12

Answer:

Explained below.

Step-by-step explanation:

The scores turned in by an amateur golfer at the Bonita Fairways Golf Course in Bonita Springs, Florida are,

Season 1: {75, 79, 80, 78, 76, 74, 76, 78}

Season 2: {72, 71, 76, 78, 86, 81, 72, 80}

(a)

Compute the mean and standard deviation of the golfer's scores as follows:

Season 1:

[tex]\bar x_{1}=\frac{1}{n_{1}}\sum x_{1}\\\\=\frac{1}{8}\times 616\\\\=77[/tex]

[tex]s_{1}=\sqrt{\frac{1}{n-1}\sum(x_{1}-\bar x_{1})^{2}}\\\\=\sqrt{\frac{1}{8-1}\times 30}\\\\=2.0702\\\\\approx 2.07[/tex]

Season 2:

[tex]\bar x_{2}=\frac{1}{n_{2}}\sum x_{2}\\\\=\frac{1}{8}\times 616\\\\=77[/tex]

[tex]s_{2}=\sqrt{\frac{1}{n_{2}-1}\sum(x_{2}-\bar x_{2})^{2}}\\\\=\sqrt{\frac{1}{8-1}\times 194}\\\\=5.26444\\\\\approx 5.26[/tex]

(b)

The primary difference in performance between the two seasons is:

[tex]\text{Diff} = \bar x_{2}-\bar x_{1}\\\\=5.26-2.07\\\\=3.19[/tex]

Given:

Decay rate: 1.5% per year = -0.015

To find:

The half life.

Solution:

The continuous exponential decay function is

[tex]A(t)=Ae^{-kt}[/tex]

where, a is initial value, -k is decay rate and t is time period.

For half life, [tex]A(t)=\dfrac{A}{2}[/tex],

[tex]\dfrac{A}{2}=Ae^{-0.015t}[/tex]

Dividing both sides by A.

[tex]\dfrac{1}{2}=e^{-0.015t}[/tex]

Taking natural log on both sides.

[tex]\ln \dfrac{1}{2}=\ln e^{-0.015t}[/tex]

[tex]-0.69314718=-0.015t[/tex]

Divide both sides by -0.015.

[tex]\dfrac{-0.69314718}{-0.015}=t[/tex]

[tex]46.209812 =t[/tex]

[tex]t\approx 46[/tex]

Therefore, the half life is 46 years.
