120 - 36 as a product with the GCF as a factor. True, we can factor out the GCF and we'll have a product:

GCF(120,36) = GCF(5(24),36)=GCF(5(12)(2),12(3)) = 12

We can factor that out and get:

120 - 36 = 12(10 - 3) = 12(7)

Answer: TRUE

How to find the GCF of three numbers.

There are a couple different ways; the obvious way is to find the GCF of the first two and then then GCF of the result and the third.

The other way is to prime factorize all three numbers; for each prime factor count how many times it occurs in each input. In the GCF it will occur the minimum of those three. Multiply the resulting powers of prime factors to get the GCF.

GCF(60,90) = GCF(30(2), 30(3)) = 30

60 + 90 = 30(2 + 3)

Xiao missed a factor of ten in the GCF.

Find the solution set of this system:

bezimeni [28]

Answer:

(−4, 12), (1, −3)

Step-by-step explanation:

y = −3x

x^2 −4 = y

x^2 −4 = −3x

x^2 + 3x - 4 = 0

(x + 4)(x - 1) = 0

x + 4 = 0; x = -4

x - 1 = 0; x = 1

when x = 1, y = -3(1) = -3

when x = -4, y = -3(-4) = 12

Answer

(-4 , 12), (1 , -3)

Please, show me how to find the limit. lim θ sin θ θ→π Thank you!

Morgarella [4.7K]

Ignore the fact that it says limit because when sin (pi) is here it is not an Undefined Point, whatever value the calculator says is sin(pi) is the answer.

Length of a rectangular prism is increased by factor of 1.5. The width is doubled and height is tripled. What is the new volume?

dimulka [17.4K]

Nine times the original volume

Step-by-step explanation:

Let the length, width and height of the rectangular prism be 'l' 'w' and 'h'.

The volume of the rectangular prism is given by,

V = W x l x h

The original volume of the rectangular prism is,

V = wlh

Here the length is 1.5 the original length

So, l = 1.5 x l = (1.5l)

And the with is doubled. So,

W = 2W

The height is tripled. So,

h = 3h

Volume of the new rectangular prism is,

V = (1.5l) (2w) (3h)

V = 9 wlh

We know that wlh is the original volume of the rectangular prism.

So the new volume is 9 times the original volume.

What is the answer a factory adds three red drops an two blue drops of coloring to white paint to make each pint of purple paint

Elan Coil [88]

Answer:

Red = 30 drops

Blue = 20 drops

Step-by-step explanation:

The ratio red to blue is 3 : 2

Sum of ratios = 3 + 2 = 5

Required purple paint = 50 gallons

So,

$Multiplier = \frac{50}{5} = 10$

Now, Red drops = 3×10 = 30

Blue drops = 2×10 = 20

Circumference of the cylinder a cylinder of the base with the diameter of 6cm and height of 12cm

yuradex [85]

Answer:

To find the volume, we must find the area of the circle and multiply it by its height, think of a cylinder as an object made up of MANY circles. So, V=pir^2h... so diameter is 6cm so radius = 3cm...

therefore, Volume = (pi)(3^2)(12) = 108(pi)

where 12 = height 3 = radius

For the surface area, we need to find the area of the 2 circles(top and bottom ) so once again,

2(pi)(r^2) = 2(pi)(9)

for the area of the rectangle(if we unfold the cylindrical can) we get D(pi)(12) where D= Diameter

so the surface area is

SA = (2)(9)(pi) + 6(pi)(12)

SA = 18pi + 72pi = 90pi
