Answer:
36
Step-by-step explanation:
Let the total number of cotton candy = A
Number of blue cotton candy = 27 cones
Percentage of blue cotton candy = 75%
Therefore, the total number of cotton candy is calculated as:
27/A × 100 = 75%
2700/A = 75
Cross Multiply
75A = 2700
A = 2700/75
A = 36
Therefore, the amount of total cotton candy that we have is 36.
Answer:
C. 50
Step-by-step explanation:
x+y=90
x=2y-30
90-y=2y-30
3y=120
y=40
90-40= 50
Answer:
D. 2
Step-by-step explanation:
soh cah toa rule
sine equals opposite over hypotenuse,
cosine equals adjacent over hypotenuse, and
tangent equals opposite over adjacent
csc is 1/sin which is hypotenuse over opposite
if csc is -√5/2 then
hypotenuse is -√5
opposite is 2
3rd quadrant on a graph is bottom left
both x and y values are negative
hypotenuse means its a triangle
pythagorean theorem
a^2 + b^2 = c^2
a^2 + 2^2 = (-√5)^2
a^2 + 4 = 5
a = 1 = adjacent
tangent equals opposite over adjacent
tan is 2 / 1 which is 2
third quadrant means it's still positive
because tan is positive in quadrant 3

Answer:
P(E) =5/9
P(F)=P(E) × P(B<Y<R) = 5/54
Step-by-step explanation:
Let E be events that gives no two number on the dice
Probability P(E) = (6 × 5× 4 )/(6×6×6)
P(E) = 130/ 216 = 5/9
Probability P(B<Y<R) = 1/6
Probability P (F) = P(E) × P(B< Y < R)
P(F) = (5/9 )×( 2/6) = 5/ 54
1 hour:
2 2/5 / 7/12
= 12/5 / 7/12
= 12/5 x 12/7
= 144/35
= 4 4/35
answer
4 4/35 miles per hour
