Answer:
Speedy Taxis
Step-by-step explanation:
I solved this by using a graphing calculator. Speedy Taxis shows the least cost for x=30.
__
You can figure the cost of each for x=30
1.5(30) = 45
1.1(30)+11.5 = 33+11.5 = 44.5 . . . . . lowest cost
1.25(30)+8 = 37.5+8 = 45.5
Speedy Taxis is the cheapest for a trip of 30 miles.
Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y = x + 4 → (1)
- x + y = - 5 → (2)
Substitute y = x + 4 into (2)
- x + x + 4 = - 5 , that is
4 = - 5 ← not possible
This indicates the system has no solution
Answer:
C
Step-by-step explanation:
The general rule is that any 2 must exceed the third in order for a triangle to form. If any one is an exception, it won't work.
A will form a triangle. Any 2 exceeds the third.
B also forms a triangle. Same rule.
C does not work. 7 + 11 = 18 which is the value of the third leg.
D words Any two exceeds the 3rd.
Answer:
The sharing cone holds about 9 times more popcorn than the skinny cone.
Step-by-step explanation:
The volume of a cone is given by the following formula:
In which r is the radius and h is the height.
Two cones:
Both have the same height.
The sharing-size cone has 3 times the radius of the skinny-size cone.
Skinny:
radius r, height h. So
Sharing size:
radius 3r, height h. So
About how many times more popcorn does the sharing cone hold than the skinny cone?
The sharing cone holds about 9 times more popcorn than the skinny cone.
