Answer:
- 16
Step-by-step explanation:
Evaluate the exponents on numerator/ denominator, that is

Cancel 125 and 243 on numerator/ denominator, leaving
= - 16
Answer:
b=-1
Step-by-step explanation:
3(b+2)+2(b-3)=-5
3b+6+2b-6=-5
5b=-5
b=-1
533,000
I can't really explain it very well but I just took my test and I got it right
Answer:
26,664 inches
Step-by-step explanation:
Set up a proportion to solve this...
33 inches is to 1.25 miles as 'x' inches is to 1,010 miles
33/1.25 = x/1,010 now solve for x by cross multiplying
33,330 = 1.25x
33,330/1.25 = x
26,664 = x
One way to solve this question is through trigonometry. :)
If you've learnt trigonometry, here are the basic formulas:
SOH CAH TOA (These formulas only apply for right-angled triangles)
Sin(angle) = (Side that is Opposite of angle)/(Hypotenuse)
Cos(angle) = (Side that is Adjacent of angle)/(Hypotenuse)
Tan(angle) = (Side that is Opposite of angle)/(Side that is Adjacent of angle)
In this case, we should use sine of b (the angle at the top of triangle as indicated in your question), where the opposite side is the base (I.e. 4 indicated in your question) and the hypotenuse is 9.
sin(b) = 4/9
{Make angle b the subject of the equation}

{Type this into the calculator}
Angle b = 26.4° (rounded off to 1 decimal place)
Hope this helps! :)
