Answer:
Number of dogs = 6
Number of burgers = 11
Step-by-step explanation:
Number of dogs = x
Number of burgers = 2x - 1
Cost of a dog = $ 1.50
Cost of 'x' dogs = 1.5x
Cost of a burger = $ 2
Cost of (2x - 1) burger = (2x -1) * 2 = 2x *2 - 1*2
= 4x - 2
Total amount collected = $ 31
1.5x + 4x - 2 = 31 {add 2 to both sides}
1.5x + 4x = 31 + 2
1.5x+ 4x = 33
5.5x = 33
x = 33/5.5
x = 6
Number of dogs = 6
Number of burgers = 2*6 - 1 = 12 - 1 = 11
Answer:
7.4*10^-5, 7300000
Step-by-step explanation:
1 There are 4 zeros in 1
round up .0000742 to .000074
There are 5 places between 7 and the last zero, negative because it is a decimal.
2 7.3*10^6= 73 is first, 6 places after 7 so 5 zeros (6 is in a place)
70 ft because 7 is bigger than 5 and 7x10=70
If the total volume of the ice cream exceeds the internal volume of the cone, then it will overflow.
Volume of icecream = 4/3 * pi * r^3 = 4/3*pi*(1)^3 = 4.189 cu. in.Volume of cone = 1/3 * pi * r^2 * h = 1/3*pi*(1)^2*5 = 5.236 cu. in.
Since Volume of cone > Volume of icecream, the cone will not overflow.
