Twice as many students go to the park than to the theater. Five more students go to the theater than to the museum. If 16 students go to the park, how many students go to the museum?

Answers

Answer:

3 students

Step-by-step explanation:

Twice as many students go to the park than to the theater :

Let number who go the theater = t

Number who goes to park = 2t

5 more students go to the theater than to the museum

Number who goes to museum = t - 5

If number of students who goes to park = 16

How many students goes to the museum :

2t = 16

t = 16/2

t = 8

Number who goes to museum = t - 5

t - 5 = 8 - 5 = 3

Hence, number of students who goes to the museum = 3

Answers

Complete question is;

You, newton, and Descartes volunteer this summer. You have 2 times as many volunteer min as newton and Descartes. You all have 5040 volunteer min altogether. how many min do you volunteer?

Answer:

2520 volunteer minutes

Step-by-step explanation:

You have 2 times as many volunteer minutes as Newton and Descartes.

Now, if Newton and Descartes each have x volunteer minutes, it means you have 2x volunteer minutes.

Since the total volunteer minutes of the 3 of you is 5040,then we have;

2x + x + x = 5040

4x = 5040

x = 5040/4

x = 1260

Since you have 2x volunteer minutes, then you have: 2 × 1260 = 2520 volunteer minutes

My sister has three Maltese puppies. Scout weighs 8 1/3 pounds. Kenadi weighs 3 1/8 pounds, and Major weighs 8 1/5 pounds. What is the order of the puppy’s weights from least to greatest?

Answers

Answer:

D) 3 1/8, 8 1/5, 8 1/3

Step-by-step explanation:

The order of the puppies' weights from least to greatest is the following:

[tex]3\frac{1}{8} , 8\frac{1}{5}, 8\frac{1}{3}[/tex]

Three wholes are less than eight wholes, which means that the puppy named Kenadi weighs the least.

Scout and Major weigh a bit more than eight pounds. However, Major weighs less than Scout because one fifth is less than one third.

[tex]8\frac{1}{5} < 8\frac{1}{3}[/tex]

This is why the correct option is D.

D

The value((2x)⁻¹) multiplied by 4x squared is represented as follows

Add a colon to the end of the statement Begin the statement with the keyword count Change the parentheses around the test condition to quotation marks Use quotation marks around the relational operator

Answers

Answer:

Add a colon to the end of the statement

Step-by-step explanation:

Given

x = 1

while(x < 26)

   print(x)

   x = x + 1

Required

Spot and fix the error

Every lines of the given code segment is correct except the second line.

The syntax of a while loop is:

while(condition):

Comparing while(condition): to while(x < 26),

we'll see that while(x < 26) has a missing colon.

So, the error in the program is a missing colon and the solution is (option a) adding a colon to the end of the while statement

So, the correct code segment is:

x = 1

while(x < 26):

   print(x)

   x = x + 1

Ishaan is 3 times as old as Christopher and is also 14 years older than Christopher.
How old is Ishaan?

Answers

Answer:

Ishaan is 21. Christopher is 7.

Answer:  Ishann is 21 years old.

Step-by-step explanation:

In this situation, we will represent Ishaan age by the variable  y and we will represent Christopher's age by x.

Ishaan is 3 times as old as Christopher and that can be represented by the equation,   y = 3x  

He is also 14 years older, and it can also be represented by the equation,  

y = x + 14.  

y= 3x

y = x + 14  

Using both equations, substitute the value of y in one of the equations into the other.

x + 14 = 3x                   Solve for x .

-x           -x

 14 = 2x  

  x = 7  

This means that Christopher is 7 years old.

To solve for Ishaan's age , input the value of x into one of the equations.

 

y = 3(7)

y = 21.
