Answer:
Step-by-step explanation:
You can solve this using algebra and cross multiplication.
($1.65/1 lb)=(x/3.2 lbs)
x(1 lb)=($1.65)*(3.2 lbs)
x (1 lb)=5.28
x=$5.28
They will cost $5.28.
Answer:
23
Step-by-step explanation:
Because 23•23=529 so the square root of 529 is 23.
Answer:
y + 7 = -
(x - 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
Where m is the slope and (a, b) a point on the line
Here m = -
and (a, b) = (1, - 7), thus
y - (- 7) = -
(x - 1), that is
y + 7 = -
(x - 1) ← in point- slope form
Answer: B. -27+452i
Step-by-step explanation: Simplify the real and imaginary parts of the expression.

Answer:
Step-by-step explanation:
Let x represent the sun's angle of elevation.
We have been given that a 6-foot tall man casts a shadow that is 12 feet long.
Upon looking at our attachment we can see that man and his shadow forma a right triangle with respect to ground, where height of man is opposite side and his shadow is adjacent side.
Since tangent relates opposite side of a right triangle with adjacent, so we can set an equation as:



Using arctan we will get,


Therefore, the measure of the sun's angle of elevation is 27 degrees.
