Answer:
Step-by-step explanation:
you have a special triangle 30-60-90
the ration in this traingle is x, x , 2x, where 2x is the hypothenuse
the hypothenuse is 12
x=12/2=6
the other leg is 6=10.39
Answer:
you should get 6 four-packs
Step-by-step explanation:
5.28/6= .88 dollars per roll
3.40/4=.85 dollars per roll
buying six four packs is a better price
Answer:
The missing value required to create a probability distribution, rounded to the nearest hundredth is 0.48.
Step-by-step explanation:
As the value given is the probability distribution, the sum of the values of the probability should be 1
Here we have
x 0 1 2 3 4
P(x) 0.04 0.09 0.19 0.2
Therefore the sum of P(x) should be equal to 1
That is 0.04 + 0.09 + 0.19 + M + 0.2 = 1
Where M is the missing value
Therefore
0.52 + M = 1 or M = 1 - 0.52 = 0.48
M = Missing value = 0.48.
Answer:
y<2x-3
Step-by-step explanation:
2(y+3)<4x
2y+6<4x
-6 -6
2y<4x-6
÷2 ÷2
y<2x-3
Given:
The vertices of a triangle are R(3, 7), S(-5, -2), and T(3, -5).
To find:
The vertices of the triangle after a reflection over x = -3 and plot the triangle and its image on the graph.
Solution:
If a figure reflected across the line x=a, then
The triangle after a reflection over x = -3. So, the rule of reflection is
The vertices of triangle after reflection are
Similarly,
And,
Therefore, the vertices of triangle after reflection over x=-3 are R'(-9,7), S'(-1,-2) and T'(-3,-5).
