Designer Dolls, Inc. found that the number N of dolls sold varies directly with their advertising budget A and inversely with the price P of each doll. The company sold 5200 dolls when $26,000 was spent on advertising and the price of a doll was set at $30. Determine the number of dolls sold when the amount spent on advertising is increased to $52,000. Round to the nearest whole number. Question 10 options: 3,447 dolls 10,400 dolls 5,200 dolls 1,723 dollsA.3,447 dolls
B.10,400 dolls
C.5,200 dolls
D.1,723 dolls

Answers

Answer 1
Answer: Direct variation: y = kx
Inverse variation: y = k/x

Using the information above about direct and inverse variation, we get this general equation.

N = kA/P

Now we use the given information to find the value of the constant, k.

5200 = k * 26,000/30

k = 6

Now we know k, so we can write the equation for this case.

N = 6A/P

A = 52,000

N = 6 * 52,000/30

N = 10,400

Answer:

0.309

Step-by-step explanation:

→ Utilise the binomial distribution formula

p=nCr*p^(n) *q^(n-r)

→ It first will be 5C2 as there is 5 possible voters but he wants 2 voters

p=5C2*p^(n) *q^(n-r)

→ Then it will be 0.3^(2) as the probability they are in favour is 0.3 and we get the n from the 2 number for the 5C2

p=5C2*0.3^(2) *q^(n-r)

→ There for q will be 0.7 as it is the other probability left and the power will be 3 as it is n - r

p=5C2*0.3^(2) *0.7^(3)

→ Then getting 0.3087 which is 0.309

Describe one way you could read the expression 0.50 x (24 + 8)

Answers

The value of the expression will be 16. Then the one way that you could read the expression by sixteen.

What is the value of the expression?

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

The expression is given below.

⇒ 0.50 x (24 + 8)

Simplify the expression, then the value of the expression will be

⇒ 0.50 x (24 + 8)

Apply the distribution property, then the expression is written as,

⇒ 0.50 x 24 + 0.50 x 8

Apply the multiplication property, then the expression can be written as,

⇒ 12 + 4

Apply the addition property, then the expression will be given as,

⇒ 16

The value of the expression will be 16. Then the one way that you could read the expression by sixteen.

How to solve 9x+5=28
-3x-10y=-26 by Elimination

Answers

so elimination
I assume that you meant to write
9x+5y=28 and not 9x+5=28
so

elimination is basically eliminating values

9x+5y=28
-3x-10y=-26
we can either cancel out the x terms or the y terms, I will cancel out the y terms

9x+5y=28
multipy both sides by 2
18x+10y=56
add to other equation


18x+10y=56
-3x-10y=-26  +
15x+0y=30
15x=30
divide both sides by 15
x=2

subsitute

9x+5y=28
9(2)+5y=28
18+5y=28
subtract 10 from both sides
5y=10
divide both sides by 5
y=2


x=2
y=2
9x + 5 = 28
      - 5   - 5
      9x = 23
       9      9
        x = 2⁵/₉

-3(2⁵/₉) - 10y = -26
    -7²/₃ - 10y = -26
  + 7²/₃             + 7²/₃
            -10y = -18¹/₃
             -10      -10
                 y = 1⁵/₆
           (x, y) = (2⁵/₉, 1⁵/₆)

Ana Participated in each charity walk she raise $.25 and each 1/2 That she walked the first day and I walked 11 miles a second day she walked 14 miles how much money did she raise

Answers

Question:

Ana participated in a charity walk. She raised $0.25 for each 1/2 mile that she walked.The first day Ana walked 11 miles.The second day, she walked 14 miles.How much money did Ana raised?

Answer:

Ana raised $ 12.5

Solution:

From given question,

First day walk = 11 miles

Second day walk = 14 miles

Let us first calculate the total distance she walked

Total distance = first day walk + second day walk

Total distance = 11 + 14 = 25 miles

Thus she walked for 25 miles

Given that,

She raised $0.25 for each 1/2 mile that she walked

(1)/(2) \text{ mile} = 0.25 \text{ dollars }

Therefore, for 1 mile we get,

(1)/(2) * 2 \text{ mile} = 0.25 * 2 \text{ dollars }\n\n1 \text{ mile } = 0.5 \text{ dollars }

Now calculate for 25 miles

25 \text{ mile } = 25 * 0.5 = 12.5 \text{ dollars }

Thus she raised $ 12.5

The circle graph shows Tommy Blox spent the money he earned last summer. If he spent $80 on entertainment, how much did Tommy earn altogether?

Answers

Answer:

Tommy earned $250 altogether.

Step-by-step explanation:

Let the total earning of Tommy be 'x' dollars.

Given:

Money spent on entertainment = $80

From the circle shown below:

Percent spent on clothes = 19%

Percent spent on food = 25%

Percent spent on other things = 14%

Percent of savings = 10%

Addition of all percents = 100%

⇒ 19% + 25% + 10% + 14% + % Entertainment = 100%

⇒ 68% + % Entertainment = 100%

⇒ % Entertainment = 100% - 68% = 32%

Therefore, as per question:

32\%\ of\ x=\$80\n\n0.32x=80\n\nx=(80)/(0.32)\n\nx=\$250\n

Hence, Tommy earned $250 altogether.
