Answer:
a) 54π cm³
Step-by-step explanation:
area of circle=πr²
9π
π9*6=54π
a) value of x:
ZX =(10x+9)°
122°=( 10x+9)
122 - 9= 10x
113= 10x
x = 113/10= 11.3 °
so answer is = 11.3°
b) measure of Arc XZ :
formula to find Arc= © angle÷360 x 2πr
A = 122÷360 x 2πr
A = 61/180x 2πr
A = 0.3388x2πr
A= 0.6776πr
The proportion equal to a/b = c/d is A.) A/C = B/D
We will know if a proportion is equivalent when its cross products are equal.
a/b = c/d where ad = bc
since ad = bc, a/c = b/d
Answer:
0.37 means that there is a 0.37 chance out of 1 or 37% chance that the player will be dealt a particular hand.
Step-by-step explanation:
Yes
if you play this card game 100 times, then you will be dealt this hand 100 * 0.37 = 37 times.
∵ ΔSRQ is a right triangle
and RT⊥SQ
∴ x² = ST * TQ
∴ x² = 9 *16 = 144
∴ x = √144 = 12
