Volume = Length x width x height
Volume = 5 1/2 x 3 x 3 = 49.5 cubic feet
Answer:
The function y = -x whose reflection in the line y =x is itself.
Step-by-step explanation:
A reflection that maps every point of a figure to an image across a fixed line. Then the fixed line is called the line of reflection.
The reflection of the point (x,y) in the line y = x is the point (y, x).
Therefore, the function y = -x whose reflection in the line y =x is itself.
Symmetries of the function f(x)= -x is:
A function symmetric with respect to the y-axis is called an even function.
If f(-x) = f(x)
A function that is symmetric with respect to the origin is called an odd function.
if f(-x) = -f(x)
then, we must look at f(-x);
f(x) = -x
f(-x)= -(-x)= x = -f(x)
this function is symmetrical to with respect to origin.
Therefore, this function is an odd function.
Answer:
20% or .20
Step-by-step explanation:
There are a total of 10 cards in the sample.
Of these 10 cards there are 2 of them with the number 8 on them.
To find the probability, you divide the part (2) over the whole (10)
2/10 = .20
Then you can multiply by 100 to find the percent
(.20)(100) = 20%
Therefore, if the teacher were to select a card at random there is a 20% chance that it has the number 8 on it.

Answer:
X=134
Step-by-step explanation:
We have two parallel lines, so the angle above x is 46.
X and angle of 46 are on the same lime, so their sum is 180, then we have.
X+46=180
X=180-46
X=134
Answer:
25.6
Step-by-step explanation:
To work this out you would first divide 65 by 10, which gives you 6.5. This is because by dividing it by 10 you are working out 10%. Then to work out 40% you would multiply 10% which is 6.5 by 4, which gives you 25.6.
1) Divide 65 by 10.
2) Multiply 6.5 by 4.
