Answer:
8 cups of ice cream
Step-by-step explanation:
1/4×8=8 cups
Answer:
a) 10.7 cm
b) 11.6 cm
c) 29.9 cm²
Step-by-step explanation:
a) sin(α)/a = sin(β)/b
sin(∠BCD)/BD = sin(DBC)/DC
sin(41°)/BD = sin(55°)/13.4
BD = 13.4*sin(41°)/sin(55°) = 10.73 cm ≈ 10.7 cm
b) From ΔBCD , ∠BDC = 180-(41+55) = 84°
∠ABD and ∠BDC are alternate interior angles, so they are congruent, and
∠ABD = ∠BDC = 84°
AD²= AB² + BD² - 2*AB*BD*cos (∠ABD) =
= 5.6² + 10.73² - 2*5.6*10.73*cos(84°) = 133.93 cm²
AD =√(133.93) ≈11.6 cm
c) Area(ADB) = (1/2)*AB*BD*sin(∠ABD)=(1/2)*5.6*10.73*sin(84°) ≈ 29.9 cm²
4+6+6+2=18(balls)
Another way 1)4+6=10(balls)-green and blue
2)6+2=8(balls)-green and blue
3)10+8=18(balls)-total probability
Answer:
x is undefined
Step-by-step explanation:
2 + 6(x - 4) = 3x - 18 + 3x
Open the bracket
2 + 6x - 24 = 3x - 18 + 3x
collect the like terms
6x -3x - 3x = -18 +24 - 2
0x = 4
x = 4/0
x is undefined
