To make the chocolate shake, Dona added 40 mL of chocolate syrup,

Vsevolod [243]

Answer:

0.225 L of milk, would be required if she uses 450 m L of water.

Step-by-step explanation:

Here, to make the shake, ingredients used by Dina are:

40 m L of chocolate syrup,

200 m L of milk, and 400 m L of water.

So, here Amount of water used = 2 x ( Amount of Milk used) ....... (1)

Now,again the amount of water used by Dona = 450 m L

Let us assume the milk used by her = k m L

⇒ 450 m L = 2 x ( k m L) ( from (1))

or, 450 = 2 k

⇒ k = 450/2 = 225

⇒ k = 225 m L

Also, 1 m L = 0.001 L

So, 225 m L = 225 x 0.001 = 0.225 L

⇒ k = 0.225 L

Hence, 0.225 L of milk, would be required if she uses 450 m L of water.

What is the equation in point slope form of a line that passes through the point (−8, 2) and has a slope of 12 ? Drag a number,

NemiM [27]

Point-slope form:

y − b = m(x − a<span>), where m is the slope and (a, b) is a point on the graph.

Here that would look like:

y - 2 = 12(x - (-8))
y - 2 = 12(x + 8)

The answer:
</span>y - 2 = 12(x + 8)

Hope this helps.

The distance in the x-coordinates from A(–2, 2) to the center of dilation F(1, 1) is unit(s).

lilavasa [31]

Answer:

The distance in the x-coordinates from A(–2, 2) to the center of dilation F(1, 1) is 3 unit(s)

Step-by-step explanation:

Give points:

$A(-2,2)$

Center of dilation $F(1,1)$

The distance in the x-coordinates fro $A$ to $F$ can be given by $=\ |x_2-x_1\ |=\ |1-(-2)\ |=\ |1+2\ | = 3\ units.$

A piece of copper wire of length 200 m has a diameter of 1.2 mm.

vova2212 [387]

The volume of the copper wire is 226.080 cm³ and the mass of the wire is 2,012.112 g/cm³.

Given that, the length of copper wire=200 m=200000 mm and the diameter of the copper wire=1.2 mm.

We need to find the volume of the copper wire.

<h3>What is the formula to find the volume of the cylinder?</h3>

The formula to find the volume of a cylinder is πr²h.

Now, the volume of the copper wire=πr²h= $\frac{22}{7} \times (0.6)^{2} \times 200000=2,26,080$ mm³=226.080 cm³

If the density of copper is 8.9 g/cm³, find the mass of the wire.

We know that $Density=\frac{Mass}{Volume} }$ .

⇒8.9 g/cm³= $\frac{Mass}{226.080}$

⇒Mass=2,012.112 g/cm³

Therefore, the volume of the copper wire is 226.080 cm³ and the mass of the wire is 2,012.112 g/cm³.
