Answer is x^2-8x+22 because there is no like terms
X = first job, y = second job
x + y < = 55
15x + 11y > = 600
there is ur system of inequalities....and I suggest going to Desmos...it is a graphing calculator.
Answer:
Step-by-step explanation:
Cylinder:
d= 6cm; r =6/2 = 3cm
h =7.5cm
Volume of ice cream in cylinder = πr²h
= π * 3 * 3 * 7.5 = 67.5 π cubic cm
Cone:
h = 6 cm;
d = 3cm ; r = 3/2 = 1.5cm
Volume =(1/3)πr²h
= (1/3) * π * 1.5 * 1.5 * 6
= π * 1.5*1.5 * 2 = 4.5π cu. cm
Hemisphere on top:
r = 1.5cm
Volume = (2/3)πr³
=(2/3)* π * 1.5 *1.5 * 1.5
= 2 *π * 0.5*1.5*1.5
= 2.25π cu.cm
Volume of ice cream in each cone = 4.5 π + 2.25π = 6.75π cubic cm
No of cones = volume of cylinder/ Volume of ice cream in each cone
=π *67.5 / 6.75 * π
= 67.5 * 100 / 6.75 * 100
= 6750 / 675
= 10
number of cones which can be filled with ice cream = 10 cones
1. Is false
2 is true
3 is false
We can write multiple equations that have the same solution.
Two of these equations could be for example:
Equation 1:
10x = 12
Equation 2:
2x-1 = 1.4
Note: when clearing x in both equations we have:
x = 1.2
Answer:
10x = 12
2x-1 = 1.4
