Answer:

72.033 ft

Step-by-step explanation:

To find this, let us set up a fraction. Since 18.47 = 1 second, y = is 3.9 seconds. Let "y" be the variable.

[tex]\frac{18.47}{1}=\frac{y}{3.9}[/tex]

Step 1: Switch sides

[tex]\frac{y}{3.9}=\frac{18.47}{1}[/tex]

Step 2: Apply rule: [tex]\frac{a}{1}=a[/tex]

[tex]\frac{y}{3.9}=18.47[/tex]

Step 3: Multiply both sides by [tex]3.9[/tex]

[tex]\frac{3.9y}{3.9}=18.47\cdot \:3.9[/tex]

Step 4: Simplify

[tex]y=72.033[/tex]

The bear can run 72.033 feet in 3.9 seconds

Answer: $4.99

Step-by-step explanation:

The store discounted all jewelry by 1/4 which means that they removed 1/4 of the price of an item off of it.

The discount on a $19.96 bracelet would therefore be:

= 1/4 * 19.96

= $4.99

This means that the item will sell for:

= 19.96 - 4.99

= $14.97

Answer:

r = 3

Step-by-step explanation:

Step 1: subtract 18 from both sides. Then you have -4r = -12

Step 2: Divide -4 to both sides and you get r= 3

Answer:

Standardized z score = 2.06

His house rent is not an outlier

Step-by-step explanation:

The mean monthly rent of students at Oxnard university is 970 with a standard deviation of 204. John`s rent is 1390. What is his standardized z-score? Is john`s rent an outlier? How high would the rent have to be to qualify as an outlier

We solve using z score formula

= z = (x-μ)/σ, where

x is the raw score = 1390

μ is the population mean = 970

σ is the population standard deviation = 204

His z score is calculated as:

z = 1390 - 970/204

z = 2.06

No his house rent is not an outlier

Answer:

x=4, y=-1. (4, -1).

Step-by-step explanation:

x+5y=-1

5x+15y=5

---------------

-5(x+5y)=-5(-1)

5x+15y=5

--------------------

-5x-25y=5

5x+15y=5

----------------

-10y=10

y=10/-10

y=-1

x+5(-1)=-1

x-5=-1

x=-1+5

x=4

Answer:

The value of given expression = - 5mx

Step-by-step explanation:

Given expression;

10xm - 8mx + 6xm - 13xm

Find:

The value of given expression

Computation:

⇒ 10xm - 8mx + 6xm - 13xm

Step 1 ;

Rearrange expression;

⇒ 10mx - 8mx + 6mx - 13mx

Step 2 ;

Adding all terms

⇒ 10mx + 6mx - 8mx - 13mx

Step 3 :

Subtract term

⇒ 16mx - 21mx

⇒ -5mx

The value of given expression = - 5mx

Answer:

3/10

Step-by-step explanation:

We have to list out the numbers that are divisible by 6 and 7 that we can find between 1 and 30

so, we have this as;

6,7,12,14,18, 21, 24,28 and 30

The count we have here is 9

The total number we have is 30

So the probability is simply the count we have divided by 30

so we have this as ; 9/30 =

3/10

Answer:

Perimeter = 18.7 units

Area = 13.5 units²

Step-by-step explanation:

Perimeter of ADEC = AD + DE + EC + AC

Length of AD = 3 units

By applying Pythagoras theorem in ΔDBE,

DE² = DB² + BE²

DE² = 3² + 3²

DE = √18

DE = 4.24 units

Length of EC = 3 units

By applying Pythagoras theorem in ΔABC,

AC² = AB² + BC²

AC² = 6² + 6²

AC = √72

AC = 8.49 units

Perimeter of ADEC = 3 + 4.24 + 3 + 8.49

                                 = 18.73 units

                                 ≈ 18.7 units

Area of ADEC = Area of ΔABC - Area of ΔBDE

Area of ΔABC = [tex]\frac{1}{2}(AB)(BC)[/tex]

                       = [tex]\frac{1}{2}(6)(6)[/tex]

                       = 18 units²

Area of ΔBDE = [tex]\frac{1}{2}(BD)(BE)[/tex]

                       = [tex]\frac{1}{2}(3)(3)[/tex]

                       = 4.5 units²

Area of ADEC = 18 - 4.5

                        = 13.5 units²
