Answer:

V = 183 mm^3

Step-by-step explanation:

The formula for the volume of a cone is V = (1/3)(base)(height).

In this case the base is a circle of radius 5 mm, meaning that its area is B = (3.14)(5 mm)^2, or 78.5 mm^2.

The height of the cone is 7 mm.

Thus, the volume of this cone is

V = (1/3)(base)(height), or

V = (1/3)(78.5 mm^2)(7 mm), which, to the nearest cubic mm is

V = 183 mm^3

In June, Tara gathered data about amusement park attendance on days with different temperatures. Tara used the equation y=−3.5x+

sergij07 [2.7K]

Answer:

Step-by-step explanation:

Given the model:

y=−3.5x+400

Number of children in amusement park = y

Temperature = x

On a certain day:

Temperature = 90°F

Number of children in park = 60

Using the model :

The predicted number of children in park when temperature is 90°F would be :

y = - 3.5(90) + 400

y = - 315 + 400

y = 85

Model prediction = 85 children

Actual figure = 60

Residual :

|Actual - predicted | = |60 - 85| = 25 children

Answer:

2500 pence (C = 2500)

Step-by-step explanation:

$C = 10t + 20m$

From the given information, t is the number of texts so essentially you will plug in the number of texts provided (150) in the place of the variable t.

$C = 10(150) + 20m$

Apply the same thing to minutes, plug in the number of minutes (50) in the place of the variable m.

$C = 10(150) + 20(50)$

Now multiply the substitutes with the co-efficient.

$C = 1500 + 1000$ (10*150=1500 & 20*50=1000)

Add the addends

C = 2500
