Peng bought 26 treadmills for her new fitness center at $1,334 each. then, she bought 19 stationary bikes for $749 each. how much did she spend on her equipment? write an expression and then solve.
9/10 / -3/15
inverting the divisor and multiplying:
= 9/10 * 15 / -3
= 9/10 * -5
= -45 / 10
= -4 1/2
the correct answer is option d : 120°
first we bring all the cos x terms to one side
2 = 5 + 6 cos x
now we bring all the numerals to one side
-3 = 6 cos x
- = cos x
∵ cos 60° = ∴ cos x = cos 60°
x = 60°
now just flip over for the negative to get 180-60 = 120
∴ the answer is 120°.
assuming you mean the us election a problem with our electron is the person who wins the most popular vote doesn't always win.
why is this a problem?
we vote for who we want as a president as it should work, but then the most elected doesn't always become president. almost like our votes do not matter and is very discouraging.
hope this !

the pythagorean theorem states
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse
4.2^2 + 16^2 = support ^2
17.64 +256 = support ^2
273.64 = support ^2
take the square root of each side
sqrt(273.64) = sqrt(support ^2)
16.54206759 = support
the support is closest to 17 cm
