Answer:
no possible solution
Step-by-step explanation:
Price of 18 chairs: 18 x 150 = $2700
Minimum number of tables to meet $4800 threshold: (4800 - 2700) ÷ 350 = 6
To reach the $4800 requirement, the store must sell a minimum of 6 tables in addition to the 18 chairs. However, it is stated that the store can ship a maximum of 20 pieces of furniture, and selling 18 chairs and 6 tables would exceed this (18 + 6 = 24), therefore there is no possible solution.
Answer:
136 square cm
Step-by-step explanation:
Area of rectangle = 18x7=126 square cm
Area of triangle = 1/2x(11-7)x(18-13) = 1/2(4)(5) = 10 square cm
126+10 = 136 square cm
Answer:
a) -3 b) -13 c) 60 d) 3/10 e) -112
Step-by-step explanation:
Answer:
90π in^3.
Step-by-step explanation:
Total Volume = volume of cylinder + volume of the hemisphere.
= πr^2h + 1/2*4/3πr^3
= π * 3^2 * 8 + 2/3 π 3^3 ( Note the radius r = 1/2 diameter = 1/2*6 = 3)
= 72π + 18π
= 90π in^3.
Answer:
x= -2, y = -2
Step-by-step explanation:
Solve the following system:
{2 y - 4 x = 4 | (equation 1)
{4 x - y = -6 | (equation 2)
Add equation 1 to equation 2:
{-(4 x) + 2 y = 4 | (equation 1)
{0 x+y = -2 | (equation 2)
Divide equation 1 by 2:
{-(2 x) + y = 2 | (equation 1)
{0 x+y = -2 | (equation 2)
Subtract equation 2 from equation 1:
{-(2 x)+0 y = 4 | (equation 1)
{0 x+y = -2 | (equation 2)
Divide equation 1 by -2:
{x+0 y = -2 | (equation 1)
{0 x+y = -2 | (equation 2)
Collect results:
Answer: {x = -2
, y = -2
