If we let x be the distance from John's Bar to Doug's bar then we can derive the expression,
(x - 10) + x = 40
The value of x from the equation is 25. This means that the distance between John's bar and Dough's bar is 15 km. Since, John's bar and Ben's bar are 60 km apart, the distance between Doug's bar and Ben's bar is 45 km.
8:5 because it’s girls to boys, and that’s the lowest you can simplify them
Answer:
symmetry about the y-axis is shown
Step-by-step explanation:
Points on the right of the line of symmetry (x=0, the y-axis) are the same distance from that line as the corresponding points on the left. (That is what makes it a line of symmetry.)
There is no point of rotation that will map one figure to the other after rotation, hence no point or rotational symmetry.
Answer:
16 feet
Step-by-step explanation:
As said in the problem statement, the angles between the top of the house, the mirror, and the ground and between Sarah's eyes, the mirror, and the ground are congruent.
We also know that Sarah and the house are perpendicular to the ground.
So if we draw a triangle from the top of the house, to the mirror, to the bottom of the house, and another triangle from Sarah's eyes, to the mirror, to Sarah's feet, we get two triangles that have the same angles. Therefore, the triangles are similar, and we can write a proportion:
4 / 5 = h / 20
h = 16
The house is 16 feet tall.
10^-3 means move decimal place 3 places to left or divide by 1000
move decimal place 3 places left
0.0030205 is normal form
