I am pretty sure the answer is 1080. To get that answer is did 135 divided by 4 then multiplied that answer by 32.

Answer:

(x, y) -------- ( -x,-y)

Rule : Rotation center (0,0) , angle of rotation 180° or -180°

Step-by-step explanation:

The vertices of the object and image have coordinates at ;

D(-4,2), --------D'( 4,-2 ),

E (-1,3), --------E'( 1,-3 ),

F (-1,-3),--------F'(1,3),

G (-3,-4),------G'( 3,4 ),

You notice that after the rotation ;

( x, y )-------change to (-x,-y),

This rule is rotation center origin angle 180°

Help pls if u can pls

sweet-ann [11.9K]

Answer and Step-by-step explanation:

8. HL theorem - Has a right angle and the legs.

9. ASA - Angle A is congruent to angle B because of interior angles theorem, side AM is congruent to side MB because of midpoint theorem, angle AMC is congruent to angle BMD because of vertical angles theorem.

10. SSS - The two sides are congruent, and the hypotenuse is shared, making it congruent.

11. SAS - The two sides are congruent, and the angle between the congruent sides are congruent.

State whether the given measurements determine zero, one, or two triangles.

Let's apply the law of sine to calculate angle C
sin(81)/26 = sin(C)/28
0.1646 = sin(C)/28 and sin(C) =1.063. Sine sin(α) cannot be > than 1, so this triangle is invalid

The circumference of an NBA-approved basketball is 29.6 in. Given that the radius of Earth is about 6400 km, how many basketball

ella [17]

Answer:

167,886,383 basketballs

Step-by-step explanation:

We are asked to find how many basketballs would take to circle around the equator. We have given the earth's radius. So, we need the formula to obtain it's perimeter. Thus:

$Perimeter = Pi*diameter [m]\\Where Pi = 3.14$

Earth's diameter is simply radius*2. It means:

$P= 3.14*6400*2 = 40,192 [km]$

On the other hand, we have a basketball crcumference; however, we need to obtain its diameter so that we can later calculate how many basketballs fit on earth's equator by simply dividing earth's circumference by a basketball's diameter.

Diameter of a basketball:

$D= Perimeter /Pi [m]$

We need to change units to fit in the international system.

29.6 in to cm = $29.6*2.54 = 75.184 [cm]$

Then:

$Diameter=75.184/3.14 = 23.94 [cm]$

We have to convert earth's perimeter in km to cm:

$Equator=40192[km]*100000=4,019,200,000 [cm]$

Finally, dividing total earth's circumference by a basketball diameter:

$Totalbasketballs=4,019,200,000/23.94= 167,886,383 [basketballs]$
