Answer:

6 is the GCF

Step-by-step explanation:

Definition of GCF: The largest number that divides two or more numbers evenly.

Factors of 48 = 1 , 2 , 3 , 4 , 6 , 8 , 12 , 16 , 24 , 48

Factors of 42 = 1, 2, 3, 6, 7, 14, 21, 42

Answer:

The gcf of 42 and 48 can be obtained like this:

The factors of 42 are 42, 21, 14, 7, 6, 3, 2, 1.

The factors of 48 are 48, 24, 16, 12, 8, 6, 4, 3, 2, 1.

The common factors of 42 and 48 are 6, 3, 2, 1, intersecting the two sets above.

In the intersection factors of 42 ∩ factors of 48 the greatest element is 6.

Therefore, the greatest common factor of 42 and 48 is 6.

Taking the above into account you also know how to find all the common factors of 42 and 48, not just the greatest.

Answer:

$A_s=179 \ yd$

Step-by-step explanation:

Area of Circle can be calculated using following formula

$A=\pi r^{2}$

Where r is radius of circle

Area of outer circle (r=11 yd)

$A_1=\pi (11)^{2}\\A_1=379.94 \ yd$

Area of inner circle (r=8 yd)

$A_2=\pi (8)^{2}\\A_2=200.96 \ yd$

Area of shaded region

$A_s=A_1-A_2$

$A_s=379.94-200.96\\A_s=179 \ yd$

What is the measure of angle J in the triangle below? A. 99 B. 42 C. 9 D. 48

Leya [2.2K]

For this use the law of sines:
$\sin( \alpha ) \div a = \sin( \beta ) \div b \\ \sin( \alpha ) \div 11 = \sin(103) \div 16$
$\frac{ \sin( \alpha ) }{11} = \frac{0.97}{16}$
cross-multiply:
16×sin (J) = 11×0.97
sin(J) = 10.72/16
sin(J) = 0.67
hit the "arcsin" button on your calculator:
${ \sin}^{ - 1} (0.67) = 42.06 = 42.1 \: deg$
therefore answer B. 42 is the correct answer!!
