Answer:
Step-by-step explanation:
Let Sally's polygon be for example a square (As) where the area is equal to the square side and Jack (Aj) has a proportional one but Sally's is nine times larger than the Jack, then:
The goal in simplifying numbers
is to reduce it that can be best seen in the eye. In here, you are given 5a x 2c x
3d. Note that 5, 2 and 3 are coefficients and a, c and d, are variables. Multiply first
the coefficients 5, 2 and 3 and you get 30. Always remember that in multiplying
numbers, especially variables, the base of the exponent must be equal. However,
you have variables of a, c and, d. You cannot multiply or add them because they
are different. So the answer is 30acd.
Answer: 25 in³
Step-by-step explanation:
We can calculate the volume of the pyramid by first calculating the volume of a prism with the same dimensions, and then dividing by 3 (all pyramids a volume that's of the volume of a prism with the same dimensions).
The volume of a prism is its base area times its height. The base would be a square, so its area is 5², which is 25. The height is 3 inches, making the prism's volume 75 in³.
The volume of the pyramid would be one-third of this value, which is 75 which is 25 in³.
Answer:
Japan - $21.95
Switzerland - $7.33
Step-by-step explanation:
Let the cost of movies in Japan be x and the cost of movies in Switzerland be y. We can write two equations that relate x to y. If we have two equations and two unknowns we can solve for x and y.
For the total cost of $80.5:
WE can write in terms of y:
and substitute into: total of $76.85:
solve for x
then y is:
