Answer:

$11.32

Step-by-step explanation:

Greeting Cards = $1.5 x 2 = $3

Wrapping Paper = $2.29 x 3 =  $6.87

Ribbon = $1.45 x 1 = $1.45

So now we must add the totals to figure out how much money Barbra spent in total.

$3 + $6.87 + $1.45 = $11.32

Find the least common denominator for these two rational expressions. x/x^2-25, c/x^2-3x-10
34kurt

Answer:

Step-by-step explanation:

Hello,

Let 's notice that

x^2-25=x^2-5^2=(x-5)(x+5) \ \ and \\\\x^2-3x-10=(x-5)(x+2) \ \text{as sum of the zeroes is 3 and the product is -10}

So the least common denominator is

(x-5)(x+5)(x+2)

hope this helps

sports warehouse had a sale on two models of baseball gloves. Model A sold for $30.00, and model B sold for $45.25. A total of 5
alexandr402 [8]

Answer:

18 model A gloves and 34 model B gloves

Step-by-step explanation:

Set up 2 equations based on the given information

Let 'x' represent the number of Model A gloves sold

Let 'y' represent the number of Model B gloves sold

Then..

$30x + $45.25y = $2,078.50  represents the total sold in dollars

    x    +     y       =    52  represents the total number of gloves sold

Solve the second equation for either variable...

   x = 52 - y            

Now plug this into the first equation...

$30(52 - y) + $45.25y = $2,078.50            {x became 52 - y}

Now solve for y...

$1,560 - $30y + $45.25y = $2,078.50

     $15.25y = $518.50   (combine y terms, subtract $1,560 from both sides)

            y =  34             (divide both sided by $15.25, dollar signs cancel out)

Helen practiced the piano 5 days last week. The list below shows the number of minutes she practiced each day: 20,25,30,20,30 Wh
LekaFEV [45]

Answer:

4

Step-by-step explanation:

Given the data:

X : 20,25,30,20,30

Mean absolute deviation :

Σ(x - xbar) / n

n = sample size = 5

xbar = ΣX / n = (20+25+30+20+30) /5

xbar = 25

((20-25) + (25-25) + (30-25) + (20-25) + (30-25)) / 5

We take the absolute values, hence, negative signs are ignored :

(5 + 0 + 5 + 5 + 5) / 5

20 / 5

= 4
