during a basketball game, your team scored three times as many 2-point field goals than it did 3-point field goals, and scored a total of 90 points. How many field goals did your team score?

Answers

Answer:

40 field goals

Step-by-step explanation:

Represent 2-point with x and 3-point with y;

Given

$x = 3y$

$2x + 3y =90$

Required

Determine x and y

$x = 3y$

$2x + 3y =90$

Substitute 3y for x in $2x + 3y =90$

$2(3y) + 3y = 90$

$6y + 3y = 90$

$9y = 90$

Divide both sides by 9

$y = 10$

Substitute 10 for y in $x = 3y$

$x = 3 * 10$

$x =30$

The number of field goals = x + y

$x + y = 30 + 10$

$x + y = 40$

Hence, the number of field goals is 40

Step-by-step explanation:

dara spends $13.02 on sandals, $9.85 on shorts, and $15.20 on a hat. how much change does she recieve back from $50

Answers

you sum up all that Dara bought, then you subtract that from fifty t get the total change of 11.93 USD.

Final answer:

The total cost of Dara's purchases was $38.07. Upon subtracting this amount from her initial $50, she is left with $11.93 change.

Explanation:

To solve the problem, you need to add up how much Dara spends and subtract that from $50. First, add the cost of the sandals, shorts, and hat together:

$13.02 for sandals
$9.85 for shorts
$15.20 for the hat

When you add these three amounts together, you get $38.07. So, Dara has spent $38.07 in total. Now, subtract that amount from $50:

$50.00 - $38.07 = $11.93

This means Dara should get back $11.93 in change.

If u rotate an object around a given point what information will you need?

Answers

Answer:

A point (a, b) rotated around a point (x, y) 180 degrees will transform to point (-(a - x) + x, -(b - y) + y). A point (a, b) rotated around the origin 270 degrees will transform to point (b - y + x, -(a - x) + y).

Step-by-step explanation:

You pick a card at random. Without putting the first card back, you pick a second card at random. [1] [2] [3]

What is P(3, greater than 2)? Write your answer as a percentage.

Answers

Probability of first getting a 3 = 4/52 = 1/13
The p(getting >2) = probability of getting one of the remaining 3's or 40 other cards ( Im taking the aces to be low value) = 43/51

Required probability = 1/13 * 43/51 = 43/663

If aces are counted high it will be 1/13 * 47/51 = 47/531
