Find (-3/7) divided (-1 1/14)

Answers

Answer 1

Answer:

2/5

Step-by-step explanation:

first, we convert the mixed fractions to improper fractions,

[tex]-1\frac{1}{14}=\frac{15}{14}[/tex]

so then we find what [tex]-\frac{3}{7}[/tex][tex]\div[/tex][tex]-\frac{15}{14}[/tex]

[tex]-\frac{3}{7}[/tex][tex]\div[/tex][tex]-\frac{15}{14}[/tex] = [tex]-\frac{3}{7} * -\frac{14}{15}[/tex]

and that equals [tex]\frac{3*14}{7*15}[/tex] , which equals [tex]\frac{42}{105}[/tex]. We can simplify that to 2/5

Answer:

b = 12.6

Step-by-step explanation:

a*2 + b*2 = c*2

6*2 + b*2 = 14*2

36 + b*2 = 196

Subtract 36 from both sides

36 + b*2 = 196

-36 -36

b*2 = 160

Find the square root of both

b = 12.64911064 or 12.6

Need help solving

Answers

Answer:

x = 1/2 or 0.5

Step-by-step explanation:

-2x + 5 = 4

-2x = 4 -5

-2x = -1

-1(-2x = -1)

2x = 1

x = 1/2 or 0.5

-2x + 5 = 4 | minus 5 from both sides
-2x =4 -5
-2x = -1 | divide both sides by -2
x= 1/2

Mrs. Simpson is frosting circular sugar cookies. Each cookie is 7 cm in diameter. How many square inches will she need to frost one dozen cookies?

Answers

Answer:

51.92 square inches

Step-by-step explanation:

Area of a circle = (pi)(r^2)

if the diameter is 7, the radius is 3.5

A = 3.14 x 3.5

A = 10.99 cm^2 for one cookie

10.99 x 12 for a dozen = 131.88 cm^2

converting cm to inches, you divide by 2.54

131.88/2.54 = 51.92 square inches.

Las abejas tienen que hacer 50.000 salidas para obtener 1 quilogramo de miel. ¿Cuántas salidas tendrá que hacer para obtener 5 quilogramos de miel?

Answers

Answer:

Tendrá que hacer 250.000 salidas para obtener 5 kilogramos de miel.

Step-by-step explanation:

Con la información proporcionada, puedes usar una regla de tres para calcular cuántas salidas tendrá que hacer para obtener 5 kilogramos de miel dado que las abejas tienen que hacer 50.000 salidas para obtener 1 kilogramo de miel:

1 kilogramo → 50.000 salidas

5 kilogramos → x

x=(5*50.000)/1

x=250.000

De acuerdo a esto, la respuesta es que tendrá que hacer 250.000 salidas para obtener 5 kilogramos de miel.

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answers

Question:

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower bed.

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answer:

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]

Step-by-step explanation:

Given

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Required

Determine an expression for the area

Area is calculated as:

[tex]Area = Length *Width[/tex]

[tex]Area = (4w^2 + 3w - 1) * (5w - 2)[/tex]

Expand

[tex]Area = 20w^3 + 15w^2- 5w - 8w^2 - 6w + 2[/tex]

Collect like terms

[tex]Area = 20w^3 + 15w^2- 8w^2 - 5w - 6w + 2[/tex]

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]

In this laboratory, we are going to maintain a username-password system by storing the usernames and passwords in a file. The file will consist of a single username and password per line with a space in between. 1. Begin by creating a class PasswordFile which has the following interface: class PasswordFile public: PasswordFile(string filename); // opens the file and reads the names/passwords in the vectors user and password. void addpw(string newuser, string newpassword); //this adds a new user/password to the vectors and writes the vectors to the file filename bool checkpw(string user, string passwd); // returns true if user exists and password matches private: string filename; // the file that contains password information vector user; // the list of usernames vector password; // the list of passwords void synch(); writes the user/password vectors to the password file The constructor accepts a filename, and reads the file one-line at a time and adds values to the vectors user and password. The function addpw adds a user/password pair to end of each vector. 2. Now create a password.txt file with some entries such as: jsmith turtle madams apple Also create a main program to test your classes : int main() PasswordFile passfile("password.txt"); passfile.addpw("dbotting","123qwe"); passfile.addpw("egomez", "qwerty"); passfile.addpw("tongyu", "liberty"); // write some lines to see if passwords match users
