If you have 3 oranges and some give you 10, you now have 13. What is the commutative property for this expression

The commutative property of multiplication tells us that it doesn't matter in what order you multiply numbers. ... For example, it doesn't matter if we multiply 5 * 4 or 4 * 5. We will end up with the same answer.

Movie theater charges $11.00 for an adult ticket and $8.00 for a child's ticket. The ticket sells 124 tickets and brings in $1181.00. How many of each ticket type did they sell?

Answer:the number of adult tickets that the movie theatre sold is 63.

the number of child's tickets that the movie theatre sold is 61

Step-by-step explanation:

Let x represent the number of adult tickets that the movie theatre sold.

Let y represent the number of child's tickets that the movie theatre sold.

The total number of tickets sold is 124. It means that

x + y = 124

Movie theater charges $11.00 for an adult ticket and $8.00 for a child's ticket. The total cost of the tickets sold is 1181. It means that

11x + 8y = 1181 - - - - - - - - - - - -1

Substituting x = 124 - y into equation 1, it becomes

11(124 - y) + 8y = 1181

1364 - 11y + 8y = 1181

- 11y + 8y = 1181 - 1364

- 3y = - 183

y = - 183/ - 3

y = 61

x = 124 - y = 124 - 61

x = 63

Can you please answer 8.6 * 7, 16 * 1.4, 12 * 14, 7.3 * 20. altogether 15 points

8.6*7=60.2, 16*1.4=22.4, 12*14=168, 7.3*20=146

8.6 times 7 =60.2

16 times 1.4=22.4

12 times 14 =168

7.3 times 20 =146

16 times 1.4=22.4

12 times 14 =168

7.3 times 20 =146

suppose someone tells you that she has a triangle with sides having lengths 2.6,8.1 and 8.6. Is this a right triangle? why or why not? Is there an angle in the triangle larger than 90 degree?

If you're only provided with the lengths of a triangle, and you're asked to determine whether or not the triangle is right or not, you'll need to rely on the Pythagorean Theorem to help you out. In case you're rusty on it, the Pythagorean Theorem defines a relationship between the legs of a right triangle and its hypotenuse, the side opposite its right angle. That relationship is a² + b² = c², where a and b are the legs of the triangle, and c is its hypotenuse. To see if our triangle fits that requirement, we'll have to substitute its lengths into the equation.

How do we determine which length is the hypotenuse, though? Knowledge that the hypotenuse is always the longest length of a right triangle helps here, as we can clearly observe that 8.6 is the longest we've been given for this problem. The order we pick the legs in doesn't matter, since addition is commutative, and we'll get the same result regardless of the order we're adding a and b.

So, substituting our values in, we have:

(2.6)² + (8.1)² = (8.6)²

Performing the necessary calculations, we have:

6.76 + 65.61 = 73.96

72.37 ≠ 73.96

Failing this, we know that our triangle cannot be right, but we do know that 72.37 < 73.96, which tells us something about what kind of triangle it is. Imagine taking a regular right triangle and stretching its hypotenuse, keeping the legs a and b the same length. This has the fact of increasing the angle between a and b. Since the angle was already 90°, and it's only increased since then, we know that the triangle has to be obtuse, which is to say: yes, there's an angle in it larger than 90°.

How many grams are in 1.48 x 10^7 micrograms

1. How many grams are there in 1.48 x 10^7 mcg

Before we were able to identify how many grams are there in the given mcg measure, let us solve first the given equation

=> 1.48 x 10^7, multiply first 10 7 times.

=> 1.48 x (10 x 10 x 10 x 10 x 10 x 10 x 10)

=> 1.48 x 10 000 000

=> 14 800 000 micrograms

How many micrograms are there in 1 gram

=> 1 grams = 1 000 000 micrograms

Thus, we need to divide 14 800 000 / 1 000 000

=> 14.8 grams

Before we were able to identify how many grams are there in the given mcg measure, let us solve first the given equation

=> 1.48 x 10^7, multiply first 10 7 times.

How many micrograms are there in 1 gram

Lydia tosses two six-sided number cubes. A) List the sample space.

B) What is the probability of Lydia rolling pairs of the same number?

C) What is the probability that at least one number will be a 3?

b) The probability of Lydia rolling pairs of the same number is 1/6.

c) The probability that at least one number will be a 3 is 11/36

What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

a) The Sample Space is

(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)

(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)

(3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6)

(4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)

(5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6)

(6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)

b) The probability of Lydia rolling pairs of the same number

= 6/36

= 1/6

c) The probability that at least one number will be a 3

= 11/36
