b] In the opposite figure : XYZL is a square, XZ = 10 cm. , m(L XZY) = 43° Calculate the perimeter of triangle XYZ ​

Answers

Answer 1

Answer:

Perimeter of Δ XYZ = 24.13

Step-by-step explanation:

In Δ XYZ is a right  triangle because the XYZL is a square.  Therefore the hypotenuse = 10; Looking at the 43° angle, XY is the side that is opposite the 43° angle and the YZ is the side that is adjacent to the 43°.

Using the trig ratios:  

XY = opposite/ hypotenuse which is Sin 43°

Sin 43° = XY/ 10

10(Sin 43°) = XY

 6.82 = XY

YZ = adjacent/hypotenuse which is Cos 43°

Cos 43° = YZ/10

10(cos 43°) = YZ

7.31 = YZ

Now the Perimeter = XY + YZ + XZ

  Perimeter = 6.82 + 7.31 + 10

  Perimeter = 24.13

Picnic Committee decided to order 2
hamburgers or 2 hot dogs for each
student, based on the students' choices.
How many hamburgers were ordered

Answers

Answer:

156 hamburgers

Step-by-step explanation:

Number of students = 120

B.Commutative Property of Multiplication
C.Associative Property of Addition
D.Associative Property of Multiplication

Answers

The answer is D. Associative Property of Multiplication.

(7a*2b)+3c=3c+(7a*2b) the property for the given expression is Option A) Commutative Property of Addition.

The given expression is (7a*2b) + 3c = 3c + (7a*2b). This equation demonstrates the Commutative Property of Addition.

The Commutative Property of Addition states that the order in which numbers are added does not affect the result.

In mathematical terms, it can be written as: a + b = b + a.

In your expression, you have terms involving both addition and multiplication. However, since addition is involved on both sides of the equation, we can focus on the addition aspect.

(7a*2b) + 3c = 3c + (7a*2b)

First, we can rearrange the terms on the left side:

7a*2b + 3c = 3c + 7a*2b

Now, observe that the terms on both sides of the equation are the same: 7a*2b and 3c.

They are just arranged in a different order. This aligns with the Commutative Property of Addition, which says the order of addition doesn't matter.

Therefore, the expression is an illustration of this property, and the correct answer is the Commutative Property of Addition (A).

In summary, the expression shows that changing the order of terms within an addition does not change the result, thus demonstrating the Commutative Property of Addition.

Step-by-step explanation:

Adding more of one substance which makes up the reactant will increase the number of product AB that will be obtained but limited by the amount of B.

The amount of reacting substances is directly proportional to the amount of product yield. This means that adding more and more of the substance which makes up the reactant increases the amount of atoms reacting to form a product.

Hence, adding more and more of only substance A will increase the product AB, however, the amount of B in the product will be limited.
