PQ is parallel to RS
Use the diagram to findeasure of angle 2​

Answers

Answer: 140

Step-by-step explanation: Since the lines are parallel, they have the same measured angles. Angle RS and angle PQ are both straight lines, meaning they are supplementary angles (180), and angle RA is 40 degrees, so you subtract 180(the total) by 40 to get the answer 140.

Answers

Answer:

to serve hot chocolate to 14 people, you need:

7/6 cups boiling water

12.25 cups milk

2  5/8 teaspoons vanilla

7/4 half & half cream

To serve cookies to 14 people you need:

2.4 (rounded) cups flour

7/8 teaspoon baking soda

7/16 teaspoon baking powder

7/8 cup butter

21/16 cups white sugar

Step-by-step explanation:

The regular recipe for hot chocolate serves 4 people.  But 14 are being served; 14 is 3.5 times as much as 4, so multiply the measurements by 3.5.

The recipe for cookies makes 16 servings of 3 cookies (4 dozen total), so you must use slightly smaller quantities.  14 is 7/8 as much as 16, so just multiply the measurements by 7/8.

3x x 5x = again dont answer just join among us FFSWVF

Answers

Answer:

15x to the power of 2

Step-by-step explanation:

3x × 5x = ?

Here we will do more than give you the solution to 3x × 5x. We will also explain and teach you how we came up with the answer, so you can understand it and solve similar problems in the future without help.

In this problem, 3 and 5 are the coefficients and two Xs are the variables. When a coefficient is next to a variable there is an invisible multiplication sign. So you could rewrite the problem as follows:

3 × x × 5 × x =

So now you can multiply what are the same. You can multiply the coefficients together and the x variables together as follows:

3 × 5 = 15

x × x = x2

Then you put the answers together and make the multiplication sign invisible again to get the following answer:

3x × 5x = 15x2
