Answer:

11 cups

Step-by-step explanation:

Not really a method just started at 10 and then realised deal d was better so go up by one so 11 and c worked out better as I timed 30 by 11 and 15 by 1 + the flat fee.

{0, 1, 2, 3, 4, . . . , 148, 149, 150} How many members of the above set are multiples of 3 but not multiples of 5? *
umka2103 [35]

Answer:

The answer is 40.  

Step-by-step explanation:

First you can simply just list the multiples of 3 from 1-150, then cancel out all the multiples of 5 so,

3, 6, 9, 12, 18, 21, 24, 27, 33, 36, 39, 42, 48, 51, 54, 57, 63, 66, 69, 72, 78, 81, 84, 87, 93, 96, 99, 102, 108, 111, 114, 117, 123, 126, 129, 132, 138, 141, 144, 147.

15,30,45, 60,75,90, 105, 120,135 and 150 are multiples of 5 and so they are not included.

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.

Multiply the binomials:<br> (W - 9) · (W + 3)<br> Enter the correct answer.
olasank [31]

Answer:

w2-6w-27

Step-by-step explanation:

FOIL

First

Outer

Inner

Last

This is the theorem that I use, so to expand, you multiply the first number in the equation so it would be w times w because in (w-9) and (w+3) w is the first term. So now you do the outer number which is the first and last number in the equation which is w and 3 and we multiply them together. now we do the inner, which are the two inner terms, which are -9 and w and we multiply them. Now we do the last terms in each ( ) which is -9 and 3 and we multiply them. This is kinda hard to get used to, but it helps so much when you are trying to expand trinomials that are multiplied together!

so we add all the answers we got for first, outer, inner and last numbers

w*w+w*3+-9*w+-9*3

w2+3w-9w-27

w2-6w-27

Hope that helps :)
