Please help i have such a low GPA and i have to get it up so i can get into high school 100 points
enyata [817]

Answer:

<em>Well, The volume of the sink shaped like a half sphere is [2000/3] π in^2.</em>

<em />

<em>a) The volume of a cylinder is the area of the base * height</em>

<em />

<em>For this part the cup has a diameter, d, of 4 in and height, h, of 8 in.</em>

<em />

<em>The area of the base is π (d/2)^2 = π (2 in)^2  =  4π in^2.</em>

<em />

<em>The volume of the cuo is 4π in^2 * 8 in = 32π in^3.</em>

<em />

<em>Then the number of cups to take the volume of [2000 / 3] π in^2 is:</em>

<em />

<em>[2000 / 3]π / [32π] = 20.83</em>

<em />

<em>Answer: 21 cups.</em>

<em />

<em>b) For this part the diameter of the cup is 8 in and the height is 8 in</em>

<em />

<em>Then the volume is π (4 in)^2 * 8 in = 128 ⇅ in^3</em>

<em />

<em>And the number of cups needed is [2000π/3] / (128π) = 5.2 </em>

<em />

<em>Answer: 5 cups. </em><em>Good Luck!</em>

<em>From ~Itsbrazts~.</em>

Find area round to nearest tength I’ll mark brainest
Vadim26 [7]

Answer:

12.5 sq. units

Step-by-step explanation:

Divide the blue triangle into two smaller triangles.

The length of their common base = 5 units

The height of the <u>yellow</u> triangle = 2 units

The height of the <u>red</u> triangle = 3 units

The area of the yellow triangle

= (5×2)÷2

= 5 sq. units

The area of the red triangle

= (5×3)÷2

= 7.5 sq. units

The total area

= 5+7.5

= 12.5 sq. units

The owner of Darkest Tans Unlimited in a local mall is forecasting the demand for November the one new tanning booth based on th
lorasvet [3.4K]

Answer:

The forecast for November is 235 if August's forecast was 145.

Step-by-step explanation:

The formula for calculating forecast using exponential smoothing is:

F_{t} = F_{t-1}  + \alpha (A_{t-1} - F_{t-1} )

Where Ft = New month forecast

           Ft-1 = Previous month forecast

           At-1 = Previous month actual value

            α = smoothing constant

We are given F₈ = 145 (forecast for August), A₈ = 200 (Actual Value for August), α = 2, and we need to compute the forecast for November. So, We will first calculate the forecast for September then October and then November, step-by-step.

So, forecast for September is:

F₉ = F₈ + α (A₈ - F₈)

    = 145 + 2*(200-145)

    = 145 + 2*55

F₉ = 255

Then, forecast for October is:

F₁₀ = F₉ + α (A₉ - F₉)

     = 255 + 2*(220-255)

     = 255 + 2*(-35)

F₁₀ = 185

The forecast for November is:

F₁₁ = F₁₀ + α (A₁₀ - F₁₀)

    = 185 + 2*(210 - 185)

F₁₁ = 235
