Answer:
3
Step-by-step explanation:
The left side of A is 1 unit
The left side of B is 3 units
The scale factor is 3
Check:
The top of A is 3 units and the top of B is 9
3*3 = 9
Answer:
yes the cost is proportional to the number of tickets
Step-by-step explanation:
for each 1 ticket added, it is $12 more
you can graph it by using the equation y=12x where x is the amount of tickets and the y-intercept is (0,0)
Step-by-step explanation:
Given that,
Mass of Ella is 56 kg and mass of Tyrone is 68 kg.
Position of Ella is 1.5 m on the ramp.
Potential energy of an object is given by :
P = mgh
It is directly proportional to the position of an object.
If Tyrone stands at the top of ramp at more height than Ella, it will have more potential energy. Hence, the correct option is (d) "If Tyrone stands at the top of a 2 m high ramp, his potential energy will be greater than Ella's."
Answer:
cos A = 12/13
Step-by-step explanation:
TanC = AB/BC = 2.4
therefore
BC = AB/2.4
Pythagorean theorem
AC = √(AB² + (AB/2.4)²) = (13/12)AB
Cos A = AB/AC = AB / (13/12)AB = 12/13
Given expression:
2x(x + 7)-(3x +1);
To distribute implies to spread a process equally in an expression. Often times, the distributive property is used for expressions inside parentheses;
2x(x + 7)-(3x +1)
Distribute 2x over the first parentheses;
the negative sign distributes over the second part
= (2x² + 14x) - 3x -1
= 2x² + 14x -3x -1
Add like terms;
= 2x² + 11x -1
This expression 2x² + 11x -1 is equal to the given one
