X=Juliana's age
r=Rich's age
(x+2)+(x*3)+5=R
You can solve it from there
Answer:
IT WOULD BE 2.5 IN decimal form or it would be 5/2 and it is equivalent to 2 and 1/2
Step-by-step explanation:
Answer:
Yes it is.
Step-by-step explanation:
Yes it is.
Rational number is the subset of:
- Whole number(Positive number+0)
- Natural number
- Negative numbers
- Fractions &
- Decimals
-9 is a decimal, and decimals are subset of rational number so -9 is a rational number.
Hope this helps ;) ❤❤❤
Recall, The arc length [s] of a section of a circle is equal to the circles radius [r] times the central angle [theta] that the arc subtends. in radians.
r = 2.5 m.
s = 3 m.
f(x) = 2 + 3cos(10π(x - 3))
f(47) = 2 + 3cos(10(3.14)(47 - 3))
f(47) = 2 + 3cos(31.4(45))
f(47) = 2 + 3cos(1413)
f(47) = 2 + 3(0.891006524)
f(47) = 2 + 2.673019573
f(47) = 4.673019573
