The formula A=lw gives the
area A of a rectangle with
length 1. What is the area in
square feet of a rug with a
length of 13 feet and width of
6 feet?

Answers

Answer 1

Answer:

78 ft^2

Step-by-step explanation:

A = lw

l = 13 ft

w = 6 ft

A = 13ft  x 6 ft

A = 78 ft^2

Multiply the length by width to find Area. The unit for Area will be feet squared because both the numbers for length and width had the same unit.

Suppose a biologist is studying the population of fish in freshwater lakes. He collects data on the number of different species of fish found in 20 lakes. The boxplot displays the results of the study with species of fish in intervals of 50. On a boxplot, the left whisker starts between 200 and 250 species and the right whisker ends at 700 species. The box begins at 300 species, ends at 500 species, and is marked with a line segment between 400 and 450 species. Create a five-number summary of the data set. Round values to the nearest 25 species.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following information about a box and whisker plot:

Interval used = 50

Position of left whisker = between 200 and 250

Termination point of right whisker = 700

Start point of box = 300

Endpoint of box = 500

Line segment in between start and endpoint lies between 400 and 450

Five Number summary of the box and whisker plot include ;

Minimum point : start point or position of the left whisker = (between 200 and 250) = 225

Maximum point : Endpoint or position of right whisker = 700

The lower quartile (Q1) : start point or left hand position where the box begins = 300

The Upper quartile (Q3) : End point or right hand position where the box ends = 500

The median (Q2) : line segment between the upper and lower quartile = (between 400 and 450) = 425

Answers

Answer:

a = -1

Step-by-step explanation:

First, combine like terms. Like terms are terms with the same amount of the same variables.

6a + 5a = -11

(6a + 5a) = -11

(11a) = -11

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Divide 11 from both sides:

(11a)/11 = (-11)/11

a = -11/11

a = -1

a = -1 is your answer.

The lengths of salamanders have a normal distribution with mean 15cm, and standard deviation 2cm. In a collection of 300 salamanders, about how many have length greater than 16.8cm? (round answers to the nearest hundredth and show your work in the sketch area at left)

Answers

Answer:

55.22 salamanders

Step-by-step explanation:

Z score formula is given as:

Z score = x - μ/σ

x = 16.8 cm

μ = mean = 15cm

σ = standard deviation 2cm

Z score = 16.8 - 15/2

= = 0.9

Probability value from Z-Table:

P(x<16.8) = 0.81594

P(x>16.8) = 1 - P(x<16.8)

1 - 0.81594

= 0.18406

In a collection of 300 salamanders, about how many have length greater than 16.8cm?

= 300 × 0.18406

= 55.218 salamanders

Approximately to the nearest hundredth = 55.22 salamanders

Therefore, 55.22 salamanders have length greater than 16.8cm

60+x-45+x=180

60-45+2x=180

15+2x=180

2x=180-15

2x=165

x=165/2

x=82.5

Answer:

x = 82.5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

x + x - 45 + 60 = 180, that is

2x + 15 = 180 ( subtract 15 from both sides )

2x = 165 ( divide both sides by 2 )

x = 82.5

Step-by-step explanation:

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. At what number(s) measures played would the sound level be at 80 decibels?

Answers

Answer:

The sound level would be at 80 decibels at 1 or 7 number of measures played

Step-by-step explanation:

Equations with Absolute Values

We have the function s to represent the sound level in decibels:

[tex]s = 10|x - 4|+ 50[/tex]

Where x is the number of measures of the music played.

We are required to find the value of x that makes s=80 decibels. We have to find the equation:

[tex]10|x - 4|+ 50 =80[/tex]

Subtracting 50:

[tex]10|x - 4| =80-50[/tex]

[tex]10|x - 4| =30[/tex]

Dividing by 10:

[tex]|x - 4| =30/10=3[/tex]

[tex]|x - 4| =3[/tex]

For the absolute value be equal to 3, its argument could be positive or negative:

[tex]x-4=3[/tex]

Or

[tex]x-4=-3[/tex]

This leads us to two solutions:

[tex]x=3+4=7[/tex]

x=7

Or

[tex]x-4=-3[/tex]

[tex]x=4-3=1[/tex]

x=1

The sound level would be at 80 decibels at 1 or 7 number of measures played

marco is 6 feet 3 inches tall. There are 2.54 centimeters in 1 inch. What is marcos height in centimeters.

Answers

Answer:

Hi

Step-by-step explanation:

Answer:

The answer is 190.5cm

Step-by-step explanation:

so solve this problem, we first need to convert marco's height to inches.

there are 12 inches in 1 foot.

multiply.

[tex]\frac{6ft}{1} *\frac{12inch}{1ft} \\72inch[/tex]

notice how ft cancel out because they are in opposite positions of the fraction.

add 72+3 to get marco's height in inches.

[tex]72+3\\75[/tex]

marco is 75inches.

with this information, we can solve for his height in cm.

write an equation.

[tex]\frac{75inch}{1} *\frac{2.54cm}{iinch}[/tex]

solve.

[tex]\frac{75inch}{1} *\frac{2.54cm}{iinch}\\190.5cm[/tex]

marco is 190.5centimeters
