What's the difference between four tenths and four hundrenths?

Let I (x) be the statement "x has an Internet connection" and C(x, y) be the statement "x and y have chatted over the Internet,"

FrozenT [24]

Answer:

Step-by-step explanation:

L(x) means that Student X has an internet connection

C(x,y) means that students X and Y have chatted over the internet

The domain for variables X and Y comprise all students in your class. We now use quantifiers or algebraic functions to express each of the statements:

(A) Jerry does not have an internet connection

L(x) = 0

Where X represents Jerry

(B) Rachel has not chatted over the internet with Chelsea

C(x,y) = 0

Where X and Y represent Rachel and Chelsea

(C) Jan and Sharon have never chatted over the internet

L(x) + L(y) = 0

Where X and Y represent Jan and Sharon. If they have NEVER chatted over (the question didn't say they have never "with each other", it says they have never chatted at all) the internet, then they've probably never had an internet connection!

(D) No one in the class has chatted with Bob

Let Y represent Bob and X1, X2, ..., Xn represent everyone else in the class.

The value of Y is not significant here (because it is raised to the power of zero and that makes it equal to 1 and when 1 is multiplied by any X value, the X value or student remains the same) but we have to put it, to represent Bob.

The quantifier here is C (X1Y°, X2Y°, X3Y°, ..., XnY°)

Can someone help me for this question?

Answer:

2x + 1y =< 300

x + y =>150 units

y <= 2x

Step-by-step explanation:

Let x and y be the numbers of corndogs and shakes that will be sold.

1. The total cost of making these items is given by the sum of:

(x)(RM2) + (y)(RM1)

A total of RM300 is allocated for the cost of these items, so:

2x + 1y =< 300 [Units are RM)

2. Sales are expected to exceed 150 units, in total. This means:

x + y =>150 units

3. Sales for the shakes is less than 2 times that of the corndogs:

y <= 2x

Add the fractions and simplify 5 2/5 + 2 10/13=

HACTEHA [7]

Simple....

you have:

$5 \frac{2}{5} +2 \frac{10}{13}$

to convert them into improper fractions:

1.) Take whole number*denominator

(5*5=25)

2.) Take what you got...and add the numerator

(25+2=27)

3.) Use the original denominator

$\frac{27}{5}$

Do the same to the other one...

2*13=26

26+10=36

$\frac{36}{13}$

Now..add...

$\frac{27}{5} + \frac{36}{13}$

But..you need a common denominator!

$\frac{27}{5} * \frac{13}{13}= \frac{351}{65}$

$\frac{36}{13} * \frac{5}{5} = \frac{180}{65}$

Now you can add!

$\frac{351}{65} + \frac{180}{65} = \frac{531}{65}$

When simplified....

$8 \frac{11}{65}$

Thus, your answer.
