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.
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
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
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.

Which statement correctly describes the relationship between △ABC and △A′B′C′ ?
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.
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.

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?
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.

name the property of multiplication by the equation 17x × 1= 17x
Final answer:
The equation 17x × 1 = 17x illustrates the Identity Property of Multiplication, indicating that multiplying by one does not change the value of a number.
Explanation:
The equation 17x × 1 = 17x demonstrates the Identity Property of Multiplication. This property states that when any number is multiplied by one, the result is the original number. It's called the identity property because one is the identity element for multiplication. Multiplication or division by the same number on both sides of an equation will not change the equality. Therefore, multiplying by one does not alter the value of the quantity.
For example, the equation could also be expressed as 1 × 17x = 17x, showcasing the Commutative Property of Multiplication, which allows us to change the order of the factors without changing the product. However, the main focus here is the identity property, as the number stays the same after multiplication by one.

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