On a hike, each hiker carries the items shown. Write an expression in simplest form that represents the weight (in pounds) carried by x hikers. Interpret the expression.

Answers

A hiker has the following items:

A sleeping bag that weighs 3.4 lb

A Camping bag that weighs 4.6 lb

And a water bottle that weighs 2.2 lb.

The expression would be:

3.4x + 4.6x + 2.2x = x

Where x is the weight that each x hikers are carrying.

You just need to add the three items and the answer would be 10.2 pounds.

We want to find the total weight that each hiker carries by adding the weights of all individual items that they carry. And then we want an expression for the total weight that x hikers carry.

These items can be seen in the image at the end of the answer.

We will see that the total weight carried by x hikers is given by:

W(x) = (10.2lb)*x

--------------------------------

First, let's find the weight that each hiker carries.

Each hiker carries:

Sleeping bag of 3.4 lb.Backpack of 4.6 lb.Water bottle of 2.2 lb.

The total weight is:

T = 3.4 lb + 4.6 lb + 2.2 lb = 10.2 lb

Then if each hiker carries 10.2 lb of weight, and there are x hikers, the total weight carried by them will be x times 10.2 lb

We have:

W(x) = (10.2lb)*x

42-24 divide 6 ; value 3

Answers

I'm not sure exactly what you're asking, but I think the answer is 18.
Final answer:

The result of the expression 42-24 divided by 6, calculated using the 'Order of Operations' rule, is 38.

Explanation:

You've asked to solve this mathematical expression: 42-24 divided by 6. To do this correctly, we must follow the 'Order of Operations,' often remembered by the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

In your problem, the operations are Subtraction and Division. Following the PEMDAS rule, we perform Division before Subtraction. Therefore, first perform 24 divided by 6, which is 4. Then, subtract that result from 42. In the end, 42 minus 4 gives us 38 as the final answer.

The value of -4 2 is _____. pls help

Answers

the answer is 16 because 4^2 = 16 but even though its negative the value is 16
Final answer:

The value of -4 squared (-4^2) is -16 because the exponent only applies to 4, not the negative sign. To include the negative in the exponent, use parentheses like (-4)^2 = 16.

Explanation:

The value of -4^2 is -16. This is because the exponent applies only to the number 4 and not the negative sign in front of the 4. In other words, -4^2 means -(4*4) which is -16. To make the negative part of the base, the operation should be placed in parentheses like (-4)^2 = 16.

A pair of running shoes cost $22.29. The store owner wanted to make a profit of $18.50. What should be the shoes’ selling price?

Answers

the running shoes should cost $40.79

Final answer:

The selling price for the running shoes should be $40.79 to include the cost price of $22.29 and the desired profit of $18.50.

Explanation:

To calculate the selling price of the running shoes to achieve a desired profit of $18.50, we simply add the cost of the shoes to the desired profit.

The cost of the shoes is $22.29, and the store owner wants to make a profit of $18.50.

Therefore, the selling price should be:

Cost of shoes: $22.29

Desired profit: +$18.50

Total selling price: $40.79

The store owner should set the selling price at $40.79 to make a profit of $18.50 on the pair of running shoes.

kok yang's mass is 2/7 of Melvin's mass. Express Melvin's mass as a fraction of Kok yang's mass? What is the ratio of Kok Yang's mass to Melvin's mass?What is the ratioof Melvin's mass to the total mass?

Answers

We start out with the only information we have – Kok Yang’s mass (k) expressed as a fraction of Melvin’s (m): k=2/7m In order to express Melvin’s mass as a fraction of Kok Yang’s, we need to find what m is equal at – and the easiest way to do this would be to remove anything but m from that side of the equation. Now, since we can add new operations to an existing equation – the only requirement is that we have to add the same operation to both of its sides -, we’ll just divide both of them by 2/7: k/(2/7)=(2/7)/(2/7)m (k/1)/(2/7)=1*m (7*k)/1*2=1*m 7/2k=m, thus only leaving m on its side, and showing what it’s equal at on the other. Melvin’s mass is 7/2 of Kok Yang’s. The ratio of Kok Yang’s mass to Melvin’s mass can be expressed as k:m or k/m, and can be derived in a similar manner and using the same equation as above: k=2/7m, except that this time we need to find what k/m is equal at. The easiest way to do this would be to once again add a new operation to both sides of the equation – this time, dividing them by m: k/m=2/7(m/m) k/m=2/7 The ratio of Kok Yang’s mass to Melvin’s is 2 to 7. The ratio of Melvin’s mass to the total mass (k+m) can be expressed as m:(k+m) or m/(k+m), and can be calculated by using one of the equations above. Since we’re looking for ratio of Melvin’s mass to something, let’s choose to use m=7/2k, and calculate the total first: k+m=k+7/2k=(2k+7k)/2=9/2k Now, we look for the ratio of m to the total: m/(k+m)=(7/2k)/(9/2k)=7/9 THe ratio of Melvin’s mass to the total mass is 7 to 9.
Final answer:

Melvin's mass expressed as a fraction of Kok Yang's mass is 7/2. The ratio of Kok Yang's mass to Melvin's mass is 2:7, and the ratio of Melvin's mass to the total mass of both combined is 7:9.

Explanation:

If Kok Yang's mass is 2/7 of Melvin's mass, we need to express Melvin's mass as a fraction of Kok Yang's mass. To do this, we set Kok Yang's mass to 1 (as a convenient reference) and Melvin's mass then becomes 7/2 times Kok Yang's mass, since 1 is 2/7 of 7/2. Therefore, Melvin's mass in terms of Kok Yang's mass is 7/2.

The ratio of Kok Yang's mass to Melvin's mass, given that Kok Yang's mass is 2/7 of Melvin's mass, is simply 2:7.

describe the relationship between: the domain, relation, and range

Answers

Relations are subsets of products A×BA×B where AA is the domain and BB the codomain of the relation.

A function ff is a relation with a special property: for each a∈Aa∈A there is a unique b∈Bb∈B s.t. ⟨a,b⟩∈f⟨a,b⟩∈f.

This unique bb is denoted as f(a)f(a) and the 'range' of function ff is the set {f(a)∣a∈A}⊆B{f(a)∣a∈A}⊆B.

You could also use the notation {b∈B∣∃a∈A[⟨a,b⟩∈f]}{b∈B∣∃a∈A[⟨a,b⟩∈f]}

Applying that on a relation RR it becomes {b∈B∣∃a∈A[⟨a,b⟩∈R]}{b∈B∣∃a∈A[⟨a,b⟩∈R]}

That set can be labeled as the range of relation RR.

Natalie walked 3/5 mile in 1/2 hour how fast did she walk in miles per hour

Answers

Our job here is to convert the given info to the rate (speed) as a unit measurement.  In other words, we need to calculate how fast Natalie walks in 1 hour.

To do this, divide the distance by the elapsed time:

3/5 mile
------------
1/2 hour

This becomes

3
--
5
==   miles/hour
1
--
2

Invert the divisor (1/2) and multiply:

3      2       6
-- * ---  = -----
5      1       5

The correct answer must include units of measurement.  It is

(6/5) mph.

The speed of Natalie in miles per hour is 1.2 mph.

The given parameters;

distance covered by Natalie, d = 3/5 miletime of motion of Natalie, t = 1/2 hour

The speed of Natalie in miles per hour is obtained by dividing the distance covered by Natalie by the time of motion.

The value of this speed is  calculated as;

[tex]speed = \frac{distance }{time} \\\\speed = \frac{3/5}{1/2} = \frac{3\times 2}{5} = \frac{6}{5} = 1.2 \ mph[/tex]

Thus, the speed of Natalie in miles per hour is 1.2 mph.

             Given:  58 ⅓  ÷  6 ⅔ = ? ;
_________________________________________________
Note:  58 ⅓  =  [ (3*58) + 1 ] / 3  = (174 + 1) / 3 = 175 / 3 ; 

             6 ⅔ =  [ (3*6) + 2 ] / 3  = (18 + 2) / 3 = 20/3 ;
_________________________________________________
So;  Rewrite:  "58 ⅓  ÷  6 ⅔ " ;  as:
_________________________________________________
                      "(175/3)  ÷  (20/3) = ??
_____________________________________
Note:  "(175/3)  ÷  (20/3)  = (175/3) * (3/20) = ?

                                       → The "3's cancel out to "1" ; since "(3÷3 = 1)" ;
________________________________________
     and we have:  "175 * (1/20) = 175/20 ;
                                      =  35/4;  or;  " ¾ " ; or, " 8.75 " .
________________________________________
Alternate method:
________________________________________
       Given:  58 ⅓  ÷  6 ⅔ = ? ;
________________________________________
→ Using calculator:

       "58 ⅓ = 58.3333333333333333.... = 175/3 " ;

          
"6 ⅔ =6.6666666666666667 = 20/3 ;
_________________________________________
58 ⅓  ÷  6 ⅔ = (58.3333333333333333) (58.3333333333333333)  ÷ (6.6666666666666667)  (6.6666666666666667) = 8.75

or; better (using a calculator):  (175 ÷ 3) ÷ (20 ÷ 3) = 8.75  .

{or:  " (175 / 3) / (20 / 3)  =  8.75 " .

a . △ABC is congruent to △A′B′C′ because you can map △ABC to △A′B′C′ using a reflection across the y-axis, which is a rigid motion.

b . △ABC is not congruent to △A′B′C′ because there is no sequence of rigid motions that maps △ABC to △A′B′C′.

c . △ABC is congruent to △A′B′C′ because you can map △ABC to △A′B′C′ using a translation 6 units to the left, which is a rigid motion.

d . △ABC is congruent to △A′B′C′ because you can map △ABC to △A′B′C′ using a translation 6 units to the right, which is a rigid motion.

Answers

answer is 

c . △ABC is congruent to △A′B′C′ because you can map △ABC to △A′B′C′ using a translation 6 units to the left, which is a rigid motion.

Left and right motion indicates change in x-value.

If we subtract 6 from the x-coordinate of each point,

A(3, 4) will be transferred to A'(3-6, 4) = A'(-3, 4).

B(4, 0) will be transferred to B'(4-6, 0) = B'(-2, 0).

C(2, 1) will be transferred to C'(2-6, 1) = C'(-4, 1).

Hence, the correct option is c. Δ ABC is congruent to Δ A'B'C' because you can mapΔ ABC to Δ A'B'C' using a translation 6 units to the left, which is a rigid motion.
