Which of the following best describes a rational exponent

Can someone help me with this question if two figures are similar but not congruent, how are they alike, and how are they differ

kenny6666 [7]

Two figures are similar if they have the same shape but not necessarily the same size although they are the same shape they are different sizes

WHY CAN'T ANYONE HELP ME? :( Jen Butler has been pricing Speed-Pass train fares for a group trip to New York. Three adults and

devlian [24]

Answer:

Children: $13

Adults: $18

Step-by-step explanation:

Well for both sets we can set up the following system of equations,

$\left \{ {{3a + 4c = 106} \atop {2a + 3c = 75}} \right.$

So first we need to solve for a in the first equation.

3a + 4c = 106

-4c to both sides

3a = -4c + 106

Divide 3 by both sides

a = -4/3c + 35 1/3

Now we plug in that a for a in 2a + 3c = 75.

2(-4/3c + 35 1/3) + 3c = 75

-8/3c + 70 2/3 + 3c = 75

Combine like terms

1/3c + 70 2/3 = 75

-70 2/3 to both sides

1/3c = 4 1/3

Divide 1/3 to both sides

c = 13

Now we can plug in 13 for c in 3a + 4c = 106,

3a + 4(13) = 106

3a + 52 = 106

-52 to both sides

3a = 54

Divide 3 by both sides.

a = 18

Thus,

an adult ticket is $18 and a children's ticket is $13.

Hope this helps :)

The sum of two numbers is 15. Using x to represent the smaller of the two numbers, translate "the sum of twice the smaller numbe

Paladinen [302]

Answer:

Step-by-step explanation: Let x be the smaller and y be the largest number.

Since x+y=13, we deduce y=13-x

Now, for the translation: "two more than the larger number" is y+2 , while "twice the smaller" is 2x

Their sum is y+2+2x

And since we know that y=13-x, we have y+2+2x=13-x+2+2=15+x

The equation y=2.16x describes the weight y of x cubic pounds of pudding. Find three solutions, list them as ordered pairs and t

loris [4]

Answer:

(1,2.16), (2,4.32) and (3, 6.48).

The solution (1,2.16) means that 1 cubic units of pudding weighs 2.16 pounds.

The solution (2,4.32) means that 2 cubic units of pudding weighs 4.32 lbs.

Step-by-step explanation:

The equation y=2.16x describes the weight y of x cubic pounds of pudding.

The three solutions of this equation are (1,2.16), (2,4.32) and (3, 6.48).

Now, solution (1,2.16) means that 1 cubic unit of pudding weighs 2.16 pounds.

Again, solution (2,4.32) means that 2 cubic units of pudding weigh 4.32 lbs. (Answer)
