Answer:
15−2(3−2x)=46
Step-by-step explanation:
15−2(3−2x)=46
Answer: y=2
Step-by-step explanation: 2 is the y intercept and the slope is 0
Convert the mixed fraction to improper fraction
13 1/8 = 105/8 ; 12 1/3 = 37/3
105 x 37
——— -—— simplify (divide 105 & 3 by 3)
8 3
35 37
—— x (multiply)
8
1295/8 = 161 7/8 square feet

Compounded Interest Rate Formula: ![\displaystyle A = P(1 + \frac{r}{n})^{nt}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A%20%3D%20P%281%20%2B%20%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D)
- <em>P</em> is principle amount
- <em>r</em> is rate
- <em>n</em> is compounded rate
- <em>t</em> is time
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>P</em> = 6000
<em>r</em> = 5% = 0.05
<em>n</em> = 1
<em>t</em> = 2.5
<u>Step 2: Find Interest</u>
- Substitute in variables [Compounded Interest Rate Formula]:
![\displaystyle A = 6000(1 + \frac{0.05}{1})^{1 \cdot 2.5}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A%20%3D%206000%281%20%2B%20%5Cfrac%7B0.05%7D%7B1%7D%29%5E%7B1%20%5Ccdot%202.5%7D)
- Simplify:
![\displaystyle A = 6000(1.05)^{2.5}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A%20%3D%206000%281.05%29%5E%7B2.5%7D)
- Evaluate:
![\displaystyle A = 6778.36](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A%20%3D%206778.36)
Answer:
A2=A1/16
Step-by-step explanation:
the surface is A=2pi*r^2+2pi*r*h=2pi*r(r+h)
A1=2*pi*4*(4+12)=8*16 pi=128 pi=128*3.14=401.92 cm^2
r2=4/4=1cm
h2=12/4=3 cm
A2=2*pi*1(1+3)=2*4pi=8pi=8*3.14=25.12 cm^2
A2=A1/16
