Answer:

The total volume of the glass is 300 cm^3.

Step-by-step explanation:

Let V represent the total glass volume.

Then (4/5)V - (2/3)V = 40 cm^3.  The LCD here is 15, so we rewrite this equation as

(12/15)V - (10/15)V = 40 cm^3, or

(2/15)V = 40 cm^3.

Solve for V by multiplying both sides of this equation by (15/2):

(15/2)(2/15)V = (15/2)(40  = 300 cm^3

The total volume of the glass is 300 cm^3.

Step-by-step explanation:

a1 = 1

a2 = a1×2 + 1/3 = 2 1/3

a3 = a2×2 + 1/3 = (a1×2 + 1/3)×2 + 1/3 = a1×4 + 2/3 + 1/3 =

= 4 + 3/3 = 5

a4 = a3×2 + 1/3 = ... = 10 1/3

b1 = 0

b2 = (b1 + 1/2)×4 = (0 + 1/2)×4 = 1/2 × 4 = 2

b3 = (b2 + 1/2)×4 = ((b1 + 1/2)×4 +1/2)×4 = 16×b1 + 16/2 + 4/2=

= 16/2 + 4/2 = 8 + 2 = 10

or (to check we made no mistake)

= (2 + 1/2)×4 = 8 + 2 = 10. => all ok, no mistake

b4 = (b3 + 1/2)×4 = ... = (10 + 1/2)×4 = 40 + 2 = 42

so, the fourth ordered pair (= the fourth elements of each sequence) is therefore (10 1/3, 42)

The value of  Avogadro's number is 6.02214076 × 10²³. The ratio of the actual mass of an element to its atomic mass is always constant which is known as  Avogadro's number.

What is one mole?

One mole consists of an Avogadro number of atoms. If you are aware of the mole quantity, you can convert a mole into grams.

The mole (symbol: mol) is the unit of material quantity used by the International System of Units. The amount of a substance determines how many elementary entities of that substance are present in an object or sample. The mole must contain precisely 6.02214076×10²³ elementary entities.

The proportionality factor that connects the number of constituent particles (often molecules, atoms, or ions) in a sample with the amount of material in that sample is called the Avogadro constant, also known as NA or L. It has a precise value of  6.02214076 × 10²³ reciprocal moles and serves as a SI defining constant.

It shows how many atoms or molecules make up one gram of an element's or compound's molecular weight. The value is "6.022 × 10²³" when the atomic mass of an element is divided by the actual mass of its atom.

Answer:

The UWU answer UwU is UwU C UwU owa owa

Step-by-step explanation:

a linear function is following

y = ax + b

that means the ratio of the y and x differences between the data points is constant (a).

an exponential function is in the form y = a^x. or some constant variations of it.

the base is constant (a), and the exponent of the constant is the variable (x).

1.

clearly exponential.

this is the typical graph of an exponential function.

it looks like y = 2^x, as e.g. f(4) = 2⁴ = 16, and the graph seems to be at least very close to this.

2.

exponential.

y = 3^(x - 0.5)

3¹ = 3

3² = 9

3³ = 27

3⁵ = 243

this is just y = 3^x shifted to the right by 0.5 units.

3.

linear.

the difference ratio between the data points is constant :

x is the row number (1, 2, 3, 4, 5, ...).

y is the number of seats per row (14, 16, 18, 20, 22, ...).

so,

(16-14)/(2-1) = 2/1 = 2

(18-16)/(3-2) = 2/1 = 2

...

(22-14)/(5-1) = 8/4 = 2

always constant (2).

4.

neither.

it is y = x²

when you compare 4. and 1. you see the clear difference between the 2 graphs.

5.

exponential.

remember, y = a^x.

well, here, a = 1/2. but that is still constant and doesnot change the principle.

the factor 10 stretches the graph a bit up (in fact, this 10 is the starting number of an exponential growth). but the function in its core is still exponential.

6.

linear.

when written that way, it just means that x = n, and for every increase of n by 1, y (f(n)) increases by +4.

so, the difference ratio stays constant (4/1 = 4).

For the given complementary angles, the measure of angle  A is found to be 45°.

For the stated question-

Angle A is complementary to Angles B.

So,

Angle A  + Angles B = 90°

Angle A = 90° - 55°

Angle A = 45°

☆ Emily has $16 more

Step-by-step explanation:

FOR JAXON:

You want to calculate the interest on $600 at 2.5% interest per year after 3 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $600.00.

r is the interest rate, 2.5% per year, or in decimal form, 2.5/100=0.025.

t is the time involved, 3....year(s) time periods.

So, t is 3....year time periods.

To find the simple interest, we multiply 600 × 0.025 × 3 to get that:

The interest is: $45.00

Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),

or 600.00 + 45.00 = 645.00.

Jaxon will have $645 after he closes his account.

FOR EMILY

You want to calculate the interest on $600 at 5.1% interest per year after 2 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $600.00.

r is the interest rate, 5.1% per year, or in decimal form, 5.1/100=0.051.

t is the time involved, 2....year(s) time periods.

So, t is 2....year time periods.

To find the simple interest, we multiply 600 × 0.051 × 2 to get that:

The interest is: $61.20

Usually now, the interest is added onto the principal to figure some new amount after 2 year(s),

or 600.00 + 61.20 = 661.20.

Emily will have $661 when she closes her account.

☆ Therefore, Emily will have $16 more than Jaxon.

An equation that combines with the given equation  x + 2y = 21 to form a system of equations with the solution x = 3 and y = 9 is 4x + y = 21.

The correct answer is an option (c)

As x = 3 and y = 9 are the solution of system of equations, the required equation must be true for x = 3 and y = 9.

Given equation is: x + 2y = 21

For x = 3 and y = 9 given equation is 3.

In order to find the required equation, we substitute the values of x and y in each equation and check whether the equation is true for x = 3 and y = 9.

a. For equation, 4x + 6y = 64

LHS = 4(3) + 6(9)

LHS = 12 + 54

LHS = 66

LHS ≠ RHS

So, this is not a required equation.

b. 2x + y = 36

LHS = 2(3) + 9

LHS = 6 + 9

LHS = 15

LHS ≠ RHS

So, this is not a required equation.

c. 4x + y = 21

LHS = 4(3) + 9

LHS = 12 + 9

LHS = 21

LHS = RHS

this is the required equation.

d. -3x + 4y = 33

LHS = -3(3) + 4(9)

LHS = -9 + 36

LHS = 27

LHS ≠ RHS

So, this is not a required equation.

e. 3x + 2y = 28

LHS = 3(3) + 2(9)

LHS = 9 + 18

LHS = 27

LHS ≠ RHS

So, this is not a required equation.

Therefore, the reuired equation is 4x + y = 21
