Answer:

235.5 units^2

Step-by-step explanation:

(3.14*5^2*9)/3 = 235.5

For this case, we have that the volume of the oblique cone is given by:

V = \frac {1} {3} A_ {b} * h

Where:

A_ {b}: Is the area of the base given by the area of a circle.

h: It is the straight height. In this case it is "9"

A_ {b} = \pi * r ^ 2\\A_ {b} = \pi * 5 ^ 2\\A_ {b} = 78.5

So:

V = \frac {1} {3} * 78.5\\V = 235.5\\V = 235.5\ cubic\ units

ANswer:

V = 235.5 cubic units

Q#1 please help t o resolve
Veseljchak [2.6K]

Answer: option. y=-1.33x; 2.67

Solution:

If y varies directly with x, the relation between y and x is:

y=kx

where k is a constant of proporcionality.

We know y=8 when x=-6. Replacing these values in the equation above:

8=k(-6)

8=-6k

Solving for k: Dividing both sides of the equation by -6:

8/(-6)=-6k/(-6)

-1.33=k

k=-1.33

Then the relation between y and x is:

y=kx→y=-1.33x

What is the value of y when x=-2?

Replacing x by -2 in the formula:

y=-1.33x→y=-1.33(-2)→y=2.66

If theres 3 apples and you take 2 away, how many do you have?
Degger [83]
The answer depends on the perspective; however, this question is often meant to be a "trick question"; with the answer being: 2 (two) apples!
_______________________________________________
The rationale behind this answer is that if there are three apples, but you "take 2 away" you now have "2" apples, because YOU are the one who "took away the 2 apples"—so presumably, YOU have the "2 apples" that YOU "took away"!

1 = 1/4(2x + 8)<br> Need help finding the answer to this!!!
PolarNik [594]

1 = 1/4(2x+8)

1 = 1/2x + 2

1 - 2 = 1/2x

(-1) = 1/2x

x = (-1) : 1/2 = (-1) × 2/1 = (-2)

Answer : x = (-2)
