Answer:
5
Step-by-step explanation:
1. according to the condition
2. when the both prices are increased the ratio is
3. when the both prices are reduced the ratio is
4. using the equations written in steps 2&3 it is possible to make up the system of the two equations:
where x=160; y=52.
5. ration x:y=5.
A. 1/2
This is because there are 6 possible outcomes. 1, 2, 3, 4, 5, and 6.
The probability of rolling 1, 5, and 6 is 3 out of 6 (3/6)
3/6 reduced is 1/2.
these questions don't need steps
First, find the scale factor.
8.4 / 7 = 1.2
9 / 7.5 = 1.2
7.2 / 6 = 1.2
Since both solids are different sizes, the solids aren't congruent.
The size ratio for all the sides are:
8.4:7
9:7.5
7.2:6
Since the scale factor isn't 1:1 this also proves that the solids are NOT congruent.
Since both solids are the same kind of shape and have an identical scale factor, the solids are similar.
Best of Luck!
Answer:
A parabola
Step-by-step explanation:
It's a quadratic equation so the graph will be a parabola.
The solutions are -2 and -7
