ANSWER:
24 points.
The amount of points Leila needs to score in her next game so that her average is 27 points per game is: 24 points.
STEP-BY-STEP EXPLANATION:
Let the amount of points Leila needs to score in her next game so that her average is 27 points per game = x
27 = total no. of points / total no. of games
27 = ( 33 + 28 + 24 + x ) / ( 3 + 1 )
27 = ( 85 + x ) / 4
27 × 4 = 85 + x
85 + x = 108
x = 108 - 85
x = 24
Answer:
(4,7) up 3 units and right 6 units is (10,10)
Step-by-step explanation:
(4,7) goes up 3 units, which becomes (4,10). (Go up: 7 + 3 = 10)
(4,10) moves to the right 6 units, which becomes (10,10). (Right: 4 + 6 = 10)
Answer:
U = tantheta - KX/mgcostheta
Step-by-step explanation:
The formula for calculating the coefficient is given by.
KX = mgsintheta - mgucostheta
Making u subject of the formula we have
U = tantheta - KX/mgcostheta
K = 165N/m
X = 12 cm = 0.12m
U = tantheta - 165*0.12/mg*costheta
The question isn't complete but with this you can fix value for the mass and angle to get the final answer easily

Answer:
Step-by-step explanation:
21)
The sine rule is expressed as
a/SinA = b/SinB = c/SinC
Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Therefore,
12/Sin 64 = x/Sin 12
Cross multiplying, it becomes
xSin 64 = 12Sin12
xSin 64 = 12 × 0.209
0.8988x = 2.508
x = 2.508/0.8988
x = 2.79
The sum of the angles in a triangle is 180 degrees. Therefore, the unknown angle in triangle is
180 - (64 + 12) = 104 degrees. Therefore,
y/Sin104 = 12/Sin64
ySin64 = 12Sin104
0.8988y = 12 × 0.9703 = 11.6436
y = 11.6436/0.8988
y = 12.95
22) we would apply the law of Cosines which is expressed as
a² = b² + c² - 2bcCosA
Therefore,
28² = 20² + 24² - 2 × 20 × 24Cosx
784 = 400 + 576 - 960Cosx
784 = 976 - 960Cosx
960Cosx = 976 - 784 = 192
Cosx = 192/960 = 0.2
x = Cos^(-1)0.2
x = 78.5°
