Step-by-step explanation:
11. shape 1 => A = ½×17×10=85m²
shape 2=> A = 17×9 =153 m²
total area = 238 m²
12. shape 1 => A = 7×3= 21 m²
shape 2=> A = 3×2 = 6 m²
total area = 27 m²
Answer:
P(red) = .3
P(yellow) = .3
75 cubes in the box
Step-by-step explanation:
The probability has to add to 1
Since the number of red cubes equals the number of yellow cubes the probability has to be the same
.4 + x+x = 1
.4 +2x = 1
2x = 1-.4
2x = .6
Divide by 2
x = .6/2
x = .3
P(red) = .3
P(yellow) = .3
We know that
P(blue) = .4 = number of blue cubes/ total number of cubes
.4 = 30/total
total = 30/.4
total = 75
Answer:
Step-by-step explanation:
5c^5-c+c^5+7c-2
add like terms
=6c^5-c+7c-2
subtract like terms
=6c^5+6c-2
=2(3c^5+3c-1)
Step-by-step explanation:
option 1 is ur answer hope this helpss bro
When angle opposite to the unknown sides and other two sides are given then we use law of cosines
Law of cosine
From the given diagram
CB = 108
AC= 55
Angle c= 59
Take square root on both sides
AB = 92.6 m
To find out angle B we use sine law
From the figure
sin(B) = 0.50916647
B = 
(0.50916647)
Angle B= 30.61 degrees
