What unit of measurement would Guatemalans typically use to measure the weight of flour?

Answers

In general, Guatemalans also use the metric system, but also some traditional units of measurement (that come from Spain) and influence from US English units. Among the Guatemalan units of measurement some are based on old Spanish units. The libra, arroba, quintal and garrafón units of weight and volume. Guatemalans use also measures like spoons and cups. Therefore, when they weigh the measure of flour, they are using either the ibra, arroba, quintal and garrafón units. Hope this helps.

Consider the equation v + 4 + v = 8. What is the resulting equation after the first step in the solution?

a. v +4 = 8 – v
b. v +4 = 8
c. 4 + v = 8 – v
d. 2v + 4 = 8

Answers

The first step is to group like terms on each side of the equation. This would give you (v + v) + 4 = 8. There is no point in writing v + v as such, so 2v + 4 = 8 would be better. This is equation d. 

d. 2v + 4 = 8. 

Answer:

The resulting equation after the first step is 2v+4=8

d is the correct option

Step-by-step explanation:

We have been given the equation v + 4 + v = 8. In order to solve it for v, we'' perform the below mentioned steps.

Add the like terms in the left hand sideSubtract 4 to both sides of the equationFinally divide both sides by 2

Hence, in the first step, we can group the like terms and combine. In the left hand side v and v are like terms and hence, we can add them

On adding v and v we get 2v

Thus, we have

[tex]v+v+4=8\\2v+4=8[/tex]

Thus, the resulting equation after the first step is 2v+4=8

true or false. If f is a function, the f(s+t) = f(s)+f(t). ...?

Answers

Can be true or false.

True:
f(x)=x
f(3+5)=3+5=8
f(3+5)=f(3)+f(5)=3+5=8

False:
[tex]f(x)=x^2 \\f(3+5)=(3+5)^2=8^2=64 \\f(3+5)=f(3)+f(5)=3^2+5^2=9+25=34 [/tex]
Final answer:

The statement is true for linear functions, but not in general for all functions.

Explanation:

The statement is true if f(x) is a linear function.

However, it is not true in general for all functions, so the statement is false.

An example of a linear function where the statement is true would be f(x) = 2x.

If we substitute s + t into the function, we get f(s + t) = 2(s + t) = 2s + 2t.

On the other hand, if we substitute f(s) + f(t) into the function, we get f(s) + f(t) = 2s + 2t.

Therefore, the equality holds and the statement is true for linear functions.

at the party 2/5 of the pizzas ordered had pepperoni .The kids ate only 1/3 of the pepperoni pizzas, while the parents ate all of the remaining pizza. How much of all the pizza ordered was eaten by the kids ? ...?

Answers

Here is the solution for the given problem above.
Given that in the whole pizza, 2/5 of it is pepperoni (which makes 3/5 of the pizza has different flavor). What we are going to find is how much of all the pizza ordered was eaten by the kids, since only 1/3 of the pepperoni pizza is eaten by them. So to solve this, we will multiply 1/3 by 2/5 and the answer would be 2/15. Therefore, the answer is 2/15 of the pizza was eaten by the kids.

How are rigid transformations used to justify the SAS congruence theorem?

Answers

(Refer to the diagram in the attached photo.)

In this diagram there is defined two Sides and an Angle in between (SAS).

Notice how there are two loose endpoints in the diagram. A single line segment can be drawn connecting the endpoints, forming a unique triangle.

If the original diagram is transformed, the dimensions and angles formed by the third line segment remains the same relative to the first two.

Therefore, if two triangles have the same SAS configuration, then they are congruent.

The method in which rigid transformations used to justify the SAS congruence theorem is given.

What is rigid transformation?

A rigid transformation (also called an isometry) is a transformation of the plane that preserves length. In a rigid transformation the pre-image and image are congruent (have the same shape and sizes).

We are given that;

Theorem is SAS

Now,

The SAS congruence theorem states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent. To prove this theorem using rigid transformations, we can start with two distinct triangles that have a pair of corresponding congruent sides and a corresponding congruent included angle23. Then we can use a translation to move one triangle so that its congruent side matches the other triangle’s congruent side. Next, we can use a rotation to align the congruent angles of both triangles. Finally, we can use another translation to move the second congruent side of one triangle to match the second congruent side of the other triangle. By doing these rigid transformations, we have shown that one triangle can be mapped onto the other triangle exactly, which means they are congruent

Therefore, by the transformations the answer will be given above.

Answer:

a. 4.85

Step-by-step explanation:

im right

? = a+b

a = 3

b= -4.85 or 1.85

it cant be negive.

so ? = 3+1.85 = 4.85

f(x)=2x*e^2x. find lim of f(x) as x--> - infinity and +infinity ...?

Answers

I am assuming it is f(x)=2x e^2x 
2x times e raised to the 2x power, and not 2 times e raised to the 2x** 

as it approaches infinity, your f(x) --> infinity 
we can see by inspection, as 2x will approach inf, and e^(2x) will approach infinity even faster. 
inf x inf = inf 

as it approaches neg infinity, your f(x) --> 0 
we can see by inspection, as 2x will approach neg inf, and e^(2x) will approach zero. 
- inf x 0 = - 0 

The minimum(or maximum) is given when the derivative = 0 
Using the product rule, 
f ' (x) = 2e^(2x) + 4x e(2x) 
f ' (x) = 2e^(2x) ( 1 + 2x ) 
We find the roots 
2e^(2x) will never equal 0 
1 + 2x = 0, x = -1/2 

The minimum value will be when x = -0.5

turns into this new system

z = 8

but z is a single number. It can't be both 8 and 3 at the same time. So there are no solutions
