Answer:
The discount is 29.95
Step-by-step explanation:
599 x .05= 29.95
There are a total of 297 students in the 7th grade. Rough estimates would say that about half of that number are boys and half are girls. Asking only 50 random girls would be biased because not only would it not be all of the girls (the number of girls would be around 148 or 149) but it would also be ignoring the roughly 148 to 149 boys there are on estimate. The sample would be biased because it would be ignoring the opinions of more than half the seventh grade.
15x = 3x + 120 (subtract both sides by 3x)
12x = 120 (divide both sides by 12)
x = 100
The surface area of a right cylinder is the sum of the areas of the lateral face and the circular bases. The lateral face is really just a rectangle with the same height as the cylinder and a length equal to the circumference of the circular base.
If the radius of the base is

and the height is

, then the surface area of the cylinder is

You're given that the area is

and the radius is

, so you have
Answer:
∠STR =
∠XYT
Step-by-step explanation:
The triangles are give congruent.△RST ≅ △TXY.
In congruent triangles corresponding angles are equal.The order of the letters in the congruent statement matters.
In the given statement the angles matching to ∠STR is ∠XYT.
Hence ,the equal angles in the congruent triangles are ∠STR = ∠XYT.
