Just multiply 5:13 by any number
10:26
15:39
20:52
25:65
etc...
PQ + QR + RS = 18
PQ = 2x - 6; QR = 1; RS = x - 4
2x - 6 + 1 + x - 4 = 18
3x - 9 = 18
3x = 27
x = 9
Answer: C. 9
Question asks for answer in units of cubic feet so all dimensions must be converted from yards to feet.
ft x ft x ft = ft^3
Look up conversion: 1 yard = 3 ft
height = 2 yd * 3 = 6 ft
width = 9 ft
length = 3 yd * 3 = 9 ft
volume = 6 ft x 9 ft x 9 ft = 486 ft^3
The line drops 3 squares for each one it moves to the right, so the slope is
.. -3/1 = -3
The 1st selection is appropriate.
_____
Given the choices, you can tell at a glance that -3 is the correct one. When it goes down to the right, the slope is negative. when the angle is steep, the slope has a magnitude greater than 1. Of the negative choices offered, {-3, -1/3}, the obvious choice is -3.
A line has a slope of ±1 when it makes a 45° angle with the x- and y-axes. Steeper than that is a slope whose magnitude is greater than 1. Shallower than that, and the slope has a magnitude less than 1.
Answer:
60
Step-by-step explanation:
In order to get this answer, we must know that a triangle's angles add up to exactly 180. Also, Angles that intersect will have congruent, opposite sides. The last thing is that a line is = 180 degrees. So, the triangle with the 94 and the 142, you can use that. the angle next to the 142 is going to be 180-142 which is 38 and since the other angle is opposite 94, as well. when you add those up u get 132 and 180-132= 48 which is the missing angle for the far right triangle. then, you get the opposite of that angle, put that in the other triangle, do the same with the 72, and add those up to get 120 and since a triagle adds up to 180, 180-120 = 60. So, 60 is your missing angle. Cheers
