An engineer created a scale drawing of a building using a scale in which 0.25 inch represents 2 feet. The length of the actual b
Nady [450]

The length of the building in the scale drawing is 31. 25 Inches

<h3>How to determine the value</h3>

From the information given, we have that;

  • Scale drawing was used
  • 0. 25 inches represents 2 feet
  • The length of the building is 250 feet

Then,

If 0. 25 inches = 2 feet

Then x inches = 250 feet

cross multiply
x × 2 = 0. 25 × 2500

Multiply through, we have;

2x = 62. 5

Make 'x' the subject by dividing both sides by 2

2x/2 = 62. 5/ 2

x = 31. 25 Inches

Thus, the length of the building in the scale drawing is 31. 25 Inches

What is the outlier of 29, 2, 28, 30, 26, 31
Vladimir [108]

Answer:

2

Step-by-step explanation:

Given the data : 29, 2, 28, 30, 26, 31

Outlier ;

Lower :Q1 - (1.5 * IQR)

Upper : Q3 + (1.5 * IQR)

Q1 = Lower quartile ; Q3 = upper quartile ; IQR = Interquartile range

Using calculator :

Q1 = 26

Q3 = 30

IQR = (Q3 - Q1) = 30 - 26 = 4

Lower : 26 - (1.5 * 4) = 20

Upper : 30 + (1.5 * 4) = 36

Hence, the number in the given data which falls outside the range is 2

You want to go to the skate park, and you have two options:
Tcecarenko [31]

Answer:

See Explanation

Step-by-step explanation:

<u>Define the variables</u>

Let the entry fee be c and the hourly rate be m

Let the number of hours be x and the total amount be y

<u>Work to solve</u>

For Sami's skate

c = 6 and m = 2

For Brad's skate

c =10 and m = 1

<u>The equations</u>

The equation is derived using: y = mx + c

For Sami's skate

y = 2x + 6

For Brad's skate

y = x + 10

<u>When the cost are the same</u>

To do this, we equate both expressions

i.e.

y = y

2x + 6 = x + 10

2x -x = 10 - 6

x = 4

i.e. the cost are the same at the 4th hour

<u>What is the cost</u>

Substitute 4 for x in any of the equations

y = x + 10

y  = 4 + 10

y  = 14

<em>The cost is $14.00</em>
