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.

Answer:

Approximately 201 squared inches.

Step-by-step explanation:

So, the composite figure is made up of a square and a semi-circle. The square has side lengths of 12 and the semi-circle has a radius of 6.

The total area of the figure would be the area of the square plus the area of the semi-circle. Thus, find the area of each individual figure.

Square:

The area of a square is given by:

$A=l^2$

Where l is the side length.

Substitute 12 for l:

$A=(12)^2\\A=144\text{ in}^2$

So the square is 144 square inches.

Semi-circle:

The area of a semi-circle is given by:

$A=\frac{1}{2}\pi r^2$

Substitute 6 for r and 3.14 for π:

$A=\frac{1}{2}(3.14)(6)^2\\ A=56.52$

Therefore, the total area is:

$TA=144+56.52\\TA=200.52\text{ in}^2\approx201\text{ in}^2$

Figure 1 shows a paperweight made from a hollow hemisphere and a hollow cone. The paperweight contains sand so that the sand exa

soldi70 [24.7K]

Answer:

13.95 cm

Step-by-step explanation:

the volume of the cone =

⅓× π r². h = 180 π

⅓×π r²×15 = 180 π

(eliminate π)

=> 5r² = 180

r² = 180/5 = 36

r=√36 = 6 cm

the volume of the sand = ½×4/3 π r³

= ⅔× π ×6³ = 144π cm³

the ratio of the volume :

144π/180π = 0.8

so the value of h = ³√0.8 x 15 = 0.93× 15

= 13.95 cm
