Answer:

Step-by-step explanation:

3. Formula of a Cylinder + Formula of a Cone = Total

V=πr^2h + V=πr^2h

/3 = total

V = 3.14 * 36 * 10 + V = 3.14 * 36 * 10/3

V = 1,130.4 + V = 376.8 = Total

4. Formula of Cone + Formula of Cone = Total

V=πr^2h

/3 + V=πr^2h

/3 = Total

V = 3.14 * 36 * 8/3 + V = 3.14 * 100 * 8 = Total

V = 301.44 + 2,512 = Total

5. Formula of a cylinder + formula of a sphere = Total

V=πr^2h + V=4

/3πr^3 = Total

V = 3.14 * 4 * 5 + V = 4/3 * 3.14 * 8

V = 62.8 + V = 33.493 = Total

DEFINITELY hope this helped,

If the difference when −15 is subtracted from a number is twice the difference when 24 is subtracted from the same number, what

kirill [66]

Answer:

The number is 39

Step-by-step explanation:

Let the unknown number be <em>x</em>:

$(x-(-15))=2(x-24)\\x+15=2x-24\\39=x\\\therefore x=39$

Solve x2 + 4x – 4 = 8 for x.

DochEvi [55]

we know that

To find the solution let's factor the equation

$x^{2} + 4x - 4 = 8$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$x^{2} + 4x = 8+4$

$x^{2} + 4x = 12$

Complete the square. Remember to balance the equation by adding the same constants to each side

$x^{2} + 4x+4 = 12+4$

$x^{2} + 4x+4 = 16$

Rewrite as perfect squares

$(x+2)^{2} = 16$

$(x+2)^{2} = 16\\ (x+2)=(+/-)\sqrt{16} \\ x1=-2+\sqrt{16} =-2+4=2\\ x2=-2-\sqrt{16} =-2-4=-6$

therefore

the answer is the option

A. –6 or x = 2

There are an infinite number of negative numbers that aren't integers. This is because integers include whole numbers with negative signs, such as -5 and -7. However, a negative fraction, decimal, rational number, or irrational number would be considered negative numbers that aren't integers. Remember, "numbers" generally means all possible values, and numbers aren't limited to integers.

In her shop lee had a piece of fabric measuring 150 meter a costumer asked her to sew 10 cushion covers each requiring 3 meters

maria [59]

Answer:

99 m

Step-by-step explanation:

The 10 covers required ...

(10 covers) × (3 m/cover) = 30 m

So the amount remaining is ...

150 m - 30 m - 21 m = 99 m

Lee has 99 m of the fabric left.
