First you simplify t/2.5=-5.2
Which is 0.4t=-5.2
Then we divide both sides by 0.4 which you get t=-13 as your answer so it's D
Answer:
1, 3, 9, 27, 81, 243, 729
Step-by-step explanation:
The powers of 3 are:
And so on...
So through 1000: 1, 3, 9, 27, 81, 243, 729
Two supplementary angles will always add up to 180 degrees, so we can let x equal one of the angles which will make the other angle 35x. If we add them together...
35x + x = 180
36x = 180
x = 180/36
x = 5
The first angle is 5 degrees.
The second angle is 35x, so 35×5 = 175 degrees.
Check by adding them together and they should add up to 180.
175 + 5 = 180
180 = 180 Yep!!
Answer:
13 ft.
Step-by-step explanation:
We can use the Pythagorean Theorem to solve this problem. The diagonals (lines from corner-to-corner) form the hypotenuses of two right triangles.
The Pythagorean states, a² + b² = c²; with a and b being the legs and c being the hypotenuse.
a = 12
b = 5
c = ?
12² + 5² = c²
144 + 25 = c²
169 = c²
√169 = √c²2
13 = c
c = 13
Here is a crude diagram showing what the room looks like with a diagonal:
