The answer is $1.80. You would take 25% of 3, which is 75, and subtract it from 3. That leaves you with $2.25, which you take 20% off, which is 0.45, and subtract that from 2.25. That leaves you with a grand total of $1.80. Hope that this helped!
One way is to divide 500 by 0.15
500/0.15=3333.3333333
the answer is about 3333 times
For section 3.01 black, number 1 is correct, but number 2 is wrong.
When you raise an exponent to an exponent, you multiply the 2 exponents.
(x^4)^5 is x^20.
Number 3 is also right.
For 3.02, you use the interest formula. (1 + i/100)^t times x
x is the amount of money you have originally. i is the interest rate, t is the time.
1,500(1.03)^5 = 1738.91111145
$1738.91
For section 3.01 red in fractional exponents the numerator are the powers and the denominator is the root.
![\sqrt[4]{a^{3} } = a^{\frac{3}{4} }](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Ba%5E%7B3%7D%20%7D%20%20%3D%20a%5E%7B%5Cfrac%7B3%7D%7B4%7D%20%7D)
Answer:
The area of triangle is 48.
Step-by-step explanation:
Given:
The vertices of triangle are (0,0),(12,0),(2,8).
Now, to find the area of triangle.
So, the coordinates of triangle are:
.
Now, to get the area of triangle we put formula:
![Area\,of\,triangle\,=\,\frac{1}{2}\left|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)\right|](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B1%7D%7B2%7D%5Cleft%7Cx_1%28y_2-y_3%29%2Bx_2%28y_3-y_1%29%2Bx_3%28y_1-y_2%29%5Cright%7C)
![Area\,of\,triangle\,=\,\frac{1}{2}\left|0(0-8)+(12)(8-0)+2(0-0)\right|](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B1%7D%7B2%7D%5Cleft%7C0%280-8%29%2B%2812%29%288-0%29%2B2%280-0%29%5Cright%7C)
![Area\,of\,triangle\,=\,\frac{1}{2}\left|0\times -8+12\times 8+2\times 0\right|](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B1%7D%7B2%7D%5Cleft%7C0%5Ctimes%20-8%2B12%5Ctimes%208%2B2%5Ctimes%200%5Cright%7C)
![Area\,of\,triangle\,=\,\frac{1}{2}\left|0+96+0\right|](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B1%7D%7B2%7D%5Cleft%7C0%2B96%2B0%5Cright%7C)
![Area\,of\,triangle\,=\,\frac{1}{2}\left|96\right|](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B1%7D%7B2%7D%5Cleft%7C96%5Cright%7C)
![Area\,of\,triangle\,=\,\frac{1}{2}\times 96](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B1%7D%7B2%7D%5Ctimes%2096)
![Area\,of\,triangle\,=\,\frac{96}{2}](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C%5Cfrac%7B96%7D%7B2%7D)
![Area\,of\,triangle\,=\,48.](https://tex.z-dn.net/?f=Area%5C%2Cof%5C%2Ctriangle%5C%2C%3D%5C%2C48.)
Therefore, the area of triangle is 48.
