In the equations above, b and c represent the price per pound in dollars, of beef and chicken, respectively, x weeks after July 1 during last summer. What was the price per pound of beef when it was equal to the price per pound of chicken?
A summer camp counselor wants to find a length, x, in feet, across a lake as represented in the sketch above. The lengths represented by AB, EB, BD and CD on the sketch were determined to be 1800 feet, 1400 feet, 700 feet and 800 feet respectively. Segments AC and DE interest at B, and ∠AEB and ∠CDB have the same measure. What is the value of x?
In triangle ABC, the measure of ∠B is 90°, BC = 16 and AC = 20. Triangle DEF is similar to triangle ABC, where vertices D, E and F correspond to vertices A, B and C respectively and each side of triangle DEF is 12the length of the corresponding side of triangle ABC. What is the value of sinF?
The dynamic pressure q generated by a find moving with velocity can be found using the formula q=12nv2 where n is the constant density of the fluid. An aeronautical engineer uses moving with velocity 1.54v. What is the ratio of the dynamic pressure of the faster fluid to the dynamic pressure of the slower fluid?
if the expression 8-i3-2i is written in the form a+bi, where a and b are real numbers, what is the value of a? (Note: i=-1)
