Answer:
-3/-2 is the correct answer
Step-by-step explanation:
i have done this stuff before so it is that because the two negatives becomes one
40% = 0.4
Explication:
40 / 100 = 0.4
Answer:
The correct option is (b).
Step-by-step explanation:
The formula for the side of a cube of surface area SA is as follows :
When SA = 180 m²
When SA = 120 m²
Difference,
So, the correct option is (b).
Answer: 212 feet
Have a look at the image shown below. On that image, I've marked key details to focus on. Namely, the bottom right triangle has the angle CAB equal to 27 degrees because of the congruent alternate interior angles. This is the reference angle we'll base everything off of.
Opposite this angle is the side BC = 108 which is the lighthouse height. Adjacent to this angle is AB = x which is unknown. The goal is to solve for x
Use the tangent rule
tan(angle) = opposite/adjacent
tan(angle CAB) = CB/AB
tan(27) = 108/x <--- substitution
x*tan(27) = 108 <--- multiply both sides by x
x = 108/tan(27) <--- divide both sides by tan(27)
x = 211.96 <-- see note below
x = 212
note: use a calculator that has the trig functions sine, cosine, etc. You'll use the tan function for tangent. Make sure your calculator is in degree mode. the result you get is approximate as shown above, which will round to 212 when rounding to the nearest whole number.
Ok, set up the proportions:

6:16 = 21:x
So, 6/16 = 21/x

56 is the total number of roadrunners in the game reserve.
Have a great day!
