We have a ratio of dollars over lire- 1.5:1200.
In order to get to 1000000 lire, we must multiply the entire ratio by 1000000/1200=833 1/3. So we have:
1.5:1200
=1.5*833 1/3 : 1200 * 833 1/3
= 1250:1000000.
So $1250 is equivalent to 1000000 lire.
4x+6x=30
10x=30
x=3.
(-4)^3 + (-5) - (-6)^3 -15
=-64-5-(-216)-15
=-69+216-15
=-69+201
=132
What...is this?
How do you necessarily know he was cheating hm?
25^1/2 is the same as the square root of 25 so the numerator of this is 5. 2^-2 is 1/2^2=1/4. So we have 5/(1/4)=5*4=20.
x>3 would be (3, infinity) and x<3 (-infinity, 3).
\(\frac{3x+9}{2}=\frac{x-4}{3}\\ =3(3x+9)=2(x-4)\\ =9x+27=2x-8\\ =7x=-35\\ =x=-5\\\)
a. 80/360 degrees= 8/36=2/9. Then the arc length of PQ must be 2/9 the circumference. The circumference is 2(pi)(10)=20pi. Then the arc lenght is 2/9*20pi=40/9pi.
b. The area must be 2/9 the total area. The area of the circle is 10^2pi=100pi. So the area of the sector formed by POQ is 2/9*100pi=200/9pi.
