Answer:
k ≥ 1
Step-by-step explanation:
Step 1: Write inequality
4(k - 5) + 12k ≥ -4
Step 2: Solve for <em>k</em>
- Distribute 4: 4k - 20 + 12k ≥ -4
- Combine like terms: 16k - 20 ≥ -4
- Add 20 to both sides: 16k ≥ 16
- Divide 16 on both sides: k ≥ 1
Answer:
125 degrees and 55 degrees
Step-by-step explanation:
No.
0.36 = 36/100 =9/25
_____
In decimal form, 10/33 = 
which is not 0.36.
Lateral Area, namely the area of its sides, namely excluding its base.
well, the pyramid is standing on one of its triangular faces, so we'll have to exclude that.
now, let's notice, is a square pyramid, so it has an 8x8 square, and it has triangular faces that have a <u>base of 8 and a height of 22</u>.
![\bf \stackrel{\textit{square's area}}{(8\cdot 8)}~~+~~\stackrel{\textit{3 triangular faces' area}}{3\left[ \cfrac{1}{2}(8)(22) \right]}\implies 64+264\implies 328](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7B%5Ctextit%7Bsquare%27s%20area%7D%7D%7B%288%5Ccdot%208%29%7D~~%2B~~%5Cstackrel%7B%5Ctextit%7B3%20triangular%20faces%27%20area%7D%7D%7B3%5Cleft%5B%20%5Ccfrac%7B1%7D%7B2%7D%288%29%2822%29%20%5Cright%5D%7D%5Cimplies%2064%2B264%5Cimplies%20328)
Answer:
A
Step-by-step explanation:
Sine we can figure out side XY by using Pythagorean Theorem (A^2+B^2=C^2) and find that XY= 5, We can use Soh Cah Toa (The ways I remember to use value charts) and we know that Cosine uses Adjacent over Hypotenuse in which therefore the answer would be 5/13
