The value of the expression at y = 2.5 is 6.25.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

y²

Substitute y = 2.5

= y²

= 2.5²

= 2.5 x 2.5

= 6.25

Thus,

The value is 6.25.

#SPJ2

In a regular polygon, the measure of an interior angle is 6.5 times the measure of an exterior angle. How many sides does the polygon have?

Answers

Answer:

15 sides

Step-by-step explanation:

Always the sum of interior angle and exterior angle = 180

Let the exterior angle = x

Interior angle = 6.5 *x = 6.5x

x + 6.5x = 180

7.5x = 180

x = 180/7.5

x = 24

Exterior angle = 24°

Sum of exterior angles of any polygon = 360

number of side = Sum of exterior angles ÷ measure of each exterior angle

= 360 ÷ 24

= 15

What is the value of x in the equation below?
2/3x=4/5

A. 2/15
B. 8/15
C. 5/6
D. 6/5

Answers

Answer:

Step-by-step explanation:

since all you need to do is set up the equation 4/5/2/3 which is basically dividing the fractions so it would be set up as this 4/5*3/2 which is 12/10 and simplifed would be 6/5 also 6/5*2/3 is 4/5 so it would be the correct answer.

The value of x is D, 6/5

A swimming pool is open for 12{3}{4} hours each day. The lifeguards work shifts that are {3}{4} hour long. How many shifts are there each day?

Answers

Answer: 17 shifts each day

Step-by-step explanation:12 3/4 decided by 3/4 is 17

Answer: He works 16 hours a day

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

121×43=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

12×41×3=483

Since 48 divided by 3 equals 16 then,

483=16

Therefore:

121÷34=16

Solution by Formulas

Apply the fractions formula for division, to

121÷34

and solve

12×41×3

=483

=16

Therefore:

121÷34=16

so a triangle equals to 180* so you’d want to add 51+103=154 and then you’d want to find 180-154= 26 then 9x3= 27 then you’d wanna minus the 1 from 27, 27-1= 26. SO THE X WOULD BE 3.

The positive change from 15 to 19 is 4.

Find the value of the fraction 4/15 and multiply the result by 100% to obtain the final answer:

4/15 = 0.26667

Multiplied by 100%, 0.26667 becomes 26.7%: the percentage change in the number of students

Solve for a:

a – 17 = -15
A. a = -32
B. a = 2
C. a = 32
D. a = 12

Answers

Answer:

Step-by-step explanation:

a-17=-15

so the whole point of solving problems like this is to get the variable on one side (a in this case) and the constants on the other side (-17 and -15 in this case).

so to get rid of the 17 because its negative you have to add 17 or do the inverse sign but whatever you do to on side you have to do to the other side so you add 17 to both side

-17+17 they cancel out

-15+17=2

so now we get that a=2

your answer would be B

hope this helps :D

In 1990 American playwright Douglas Larche premiered Angels in the Snow: The Berlin Wall Musical Drama. The play tells the story of two couples, a minister and his wife and a young engaged couple, who are separated from one another when the wall goes up overnight. The couples struggle for 28 years to be reunited. As you read the information below about the Berlin Wall, think about what those years might have been like. Then answer the question that follows. In the aftermath of World War II, Germany was divided in two East Germany (under Communist rule) and West Germany (a free, democratic republic). As communism failed to meet peoples needs, more and more refugees began fleeing from East Germany to the west. In the first seven months of 1961 alone, more than 160,000 refugees were counted. East Germany denied plans to build a wall to stop the flood of people. Early in the morning of Sunday, August 13, 1961, however, under the direction of Erich Honecker, the East Germans began to block off East Germany from West Germany by means of barbed wire and antitank obstacles. Workers tore up streets and made barricades from paving stones. Tanks gathered at crucial places. Subway and railway service ceased. Thousands of people from both sides were separated from their homes and families. In the days that followed, East German construction brigades replaced the temporary barriers with a solid wall. The resulting barrier was over 103 miles in length, with more than 66 of those miles being solid wall. Houses near the wall were evacuated, and people approaching the wall were shot. As the world changed, the benefits of freedom and democracy as well as the failings of communism became increasingly evident. In 1989 a massive group of East Germans escaped through Hungary; there were large demonstrations of unrest in Leipzig each Monday. Communist resolve was crumbling, and on November 9, 1989, at about 7:00 P.M., the leader of East Berlins Communist Party, Gnter Schabowski, suggested that the border be opened for private trips abroad. East Berliners rushed to the Brandenburg Gate and West Berliners to the Kurfrstendamm to celebrate. On November 10, demolition work began to create new border crossings. Two days later, the Potsdamer Platz checkpoint was opened. On December 22, a checkpoint for pedestrians opened at the Brandenburg Gate. Wall woodpeckers began hammering out pieces of wall to be sold as souvenirs, and a few larger segments were officially donated or sold. On July 1, 1990, East and West Germany were reunited, and all travel restrictions were dropped. By 1991 the Wall had almost completely vanished. On August 13, 1998, a memorial consisting of about 76 yards of the remaining Berlin Wall was dedicated at Bernauer Street. When Douglas Larche was named playwright-in-residence at the University of Wisconsin-Marinette, his musical about the Berlin Wall was presented as a way to formally introduce him to the public. One reviewer described the songs in the play as beautiful and touching. They include German tunes, Christmas carols, and deep expressions of politics and heartbreak. Why would each type of song be appropriate, given the history of the Wall? Find the missing length of the triangle.10 in.1626 in. Please help! And Ill mark you as the brainiest!!!
