Winston would need to sell 14 more hot dogs to earn $175

Step-by-step explanation:

The given is:

  • Winston earns $140 by selling 56 hot dogs
  • He is using the same rate for the cost of one hot dog
  • He want to earn $175

We need to find how many more hot dogs would Winston need to sell to earn $175

∵ The he sold 56 hot dogs for $140

- Find the price of each hot dog by dividing 140 by 56

∴ The price of each hot dog = 140 ÷ 56 = 2.5

∴ The price of each hot dog is $2.5

∵ He need to earn $175

∵ He sells all hot dogs by the same price

- Divide 175 by 2.5 to find the number of the hot dogs

∵ 175 ÷ 2.5 = 70

∴ He must sell 70 hot dogs to earn $175

∵ He already sold 56

- Subtract 56 from 70 to find how many more hot dogs he

   needs to sell

∵ 70 - 56 = 14

∴ He must sell another 14 hot dogs to earn that money

Winston would need to sell 14 more hot dogs to earn $175

Find the value of x
marshall27 [118]

Answer:

x = 22

Step-by-step explanation:

(x+1)+(3x+1) = 4x+2

4x+2=90°

Solve for x:

4 x + 2 = 90

Subtract 2 from both sides:

4 x + (2 - 2) = 90 - 2

2 - 2 = 0:

4 x = 90 - 2

90 - 2 = 88:

4 x = 88

Divide both sides of 4 x = 88 by 4:

(4 x)/4 = 88/4

4/4 = 1:

x = 88/4

The gcd of 88 and 4 is 4, so 88/4 = (4×22)/(4×1) = 4/4×22 = 22:

Answer: x = 22

Bouncing Baby Company sells their cribs for the following amounts to stores
xz_007 [3.2K]

Answer:

Option C

Step-by-step explanation:

Since, Price of cribs (P) are proportional to the proportional to the number of cribs (N) sold,

P ∝ N

P = kN

Here 'k' is the proportionality constant

To get the value of proportionality constant,

Since, value of 10 cribs is $1320

1320 = k(10)

k = 132

Therefore, equation will be

P = 132N

Option A

If number of cribs = 6

P = 132(6) = $792

False.

Option B

For N = 22

P = 132(22) = $2904

False.

Option C

For N = 40

P = 132(40) = $5280

True

Option D

For N = 55

P = 132(55) = $7260

False

Option E

For N = 80

P = 132(80)

  = $10560

False

Option F

For N = 250

P = 132(250)

  = $33000

False

If the given options have been written correctly only one option, Option (C) is correct.

sergij07 [2.7K]

Answer:

a) sample size is 40

Step-by-step explanation:

(a)

\sigma=4 minutes

Margin of error, E is 75 seconds E=75/60= 1.25 minutes.

The level of significance \alpha= 0.05 for 95% level of significance

For 95% confidence interval z_{\frac{\alpha}{2}}=1.96 from standard deviation table

Sample size required, n

n=\left (\frac{z_{\frac{\alpha}{2}}\cdot \sigma}{E} \right )^{2}=\left (\frac{1.96\cdot4}{75/60} \right )^{2}=39.337984

Rounding off, n=40

Sample size =40
