What is the basic unit of weight in the metric system

Answers

Welllll ... Weight is not actually a 'basic' unit at all.

'Mass' is, and its unit is the kilogram.

'Weight' is a 'force' ... a derived unit ... made up
of mass and acceleration. The unit of force is
the (kg-meter/sec²), called the "Newton"

(1 newton) is the force that accelerates (1 kilogram of mass)
at the rate of (1 meter per second) every second.

Solve P = 2w + 2l for l.

Answers

Answer:

option a

Step-by-step explanation:

We will simply rearrange the equation for $\ell$ .

$\twoheadrightarrow\quad\sf{P=2w+2l}$

$\twoheadrightarrow\quad\sf{P-2w=2l}$

$\twoheadrightarrow\quad\sf{\cfrac{P-2w}{2}=l}$

Therefore, option A is correct

What is the inquality

Answers

Answer:

Step-by-step explanation:

Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =. ... An equation or an inequality that contains at least one variable is called an open sentence.

An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. a ≠ b says that a is not equal to b. a < b says that a is less than b. a > b says that a is greater than b. (those two are known as strict inequality)

Difference in size,degree,circumstances etc lack of equality.

Gabriel is at the grocery store, and wants to figure out his total cost before he gets to the register. He bought 2.5 pounds of apples that are x dollars a pound and 2 bags of lettuce for y dollars each. Gabriel remembers he has a coupon for $2 off his bill. Which expression gives the new amount he will pay?

Answers

The expression that gives the new amount he will pay from the purchase that Gabriel made at the grocery store is 2.5x + 2y - $2

What are word problems?

Word problems in mathematics involve a careful understanding and interpretation of the variables given. This is because it is from these variables we will compute an equation to solve the word problem.

In this question, we are being told that:

Gabriel bought 2.5 pounds of apples at x dollars.
He also bought 2 bags of lettuce at y dollars.

So, the total amount of apples and lettuce bought is:

Total amount to be paid = 2.5x + 2y.

However, he had a coupon for $2 off his total bills. It implies the new amount he will pay will be:

New amount = 2.5x + 2y - $2

Look at the parallelogram ABCD shown below: The table below shows the steps to prove that if the quadrilateral ABCD is a parallelogram, then its opposite sides are congruent: Statement Reasons 1 AB is parallel to DC and AD is parallel to BC Definition of parallelogram 2
angle 1 = angle 2, angle 3 = angle 4 If two parallel lines are cut by a transversal then the _______________ are congruent 3
BD = BD Reflexive Property 4
triangles ADB and CBD are congruent If two angles and the included side of a triangle are congruent to the corresponding angles and side of another triangle then the triangles are congruent by ASA postulate 5
AB = DC, AD = BC Corresponding parts of congruent triangles are congruent
Which choice completes the missing information for reason 2 in the chart?
alternate interior angles
corresponding angles
same-side interior angles
vertical angles

Answers

Answer:

The correct option is 1.

Step-by-step explanation:

Statement Reasons

1. AB is parallel to DC and Definition of parallelogram

AD is parallel to BC

2. angle 1 = angle 2, If two parallel lines are cut by a

angle 3 = angle 4 transversal then the alternate

interior angles are congruent

3. BD = BD Reflexive Property

4. $\triangle ADB\cong \triangle CBD$ ASA postulate

5. AB = DC, AD = BC (CPCTC)

If two angles and the included side of a triangle are congruent to the corresponding angles and side of another triangle then the triangles are congruent by ASA postulate.

According to alternate interior angles theorem, two parallel lines are cut by a transversal then the alternate interior angles are congruent.

Therefore option 1 is correct.
