The total weight of the brass returned is 4.04 lb

In this question, we have to find the total conversion of brass return with 450 so multiply the conversion rate by the live rounds return back then we will get our exact answer as follows

A unit received rounds of .9mm = 1000

They return the number of live round units = 450

They return the number of live round units with a brass conversion = .009

so,

  The total weight of the brass returned = 450 × .009

   The total weight of the brass returned with a brass conversion = 4.05 lb

The number of atoms of each element in CO2 are; Number of O atoms = 2 and Number of C atoms = 1

The number of atoms present in the molecule of an element is known as its Atomicity. For Example: In the H2O molecule, its atomicity is 3 as it has 2 molecules of hydrogen and 1 molecule of oxygen

Similarly, for the antiperspirant  Al₂Cl(OH)₅. the number of atoms in each element can be found as follows;

Number of Al atoms = 2

Number of Cl atoms = 1

Number of H atoms = 1 x 5 = 5

Number of O atoms = 1 x 5 = 5

Applying the above to our question gives;

The measure of the angle TRS = 46°

The angles given in figure are :

angle QSR = 110°

angle STR = 64°

angle QRS = 2x-10°

We will find the angle TRS using these given angles and some angle properties in a triangle.

We have the fact that sum of three angles of a triangle = 180°

So angle TRS + angle RST + angle STR = 180°

angle QSR and angle RST are supplementary. i.e., their sum = 180°

So angle RST = 180° - 110° = 70°

So angle TRS = 180°- (70°+64°) = 46°

Using angle TRS we can also find angle QRS and thereby, the value of x.

From the figure, angle QRT = 90°.

So angle QRS = 90°-angle TRS

⇒ 2x - 10° = 90° - 46°

⇒ 2x = 44° + 10°

⇒ x = 54°/2

⇒ x = 27°

The solution of the given expression will be ( 2.4 x 10⁸ ).

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that 2 x 10⁸ = 20 × 10⁷. The sum of the two exponential numbers will be calculated as:-

Sum = 2 x 10⁸  + ( 4 x  10⁷ )

Sum = 20 x  10⁷ + ( 4 x  10⁷ )

Sum = ( 20 + 4 ) x  10⁷

Sum  = 24 x  10⁷

Sum = 2.4 x 10⁸

1. The total bill that the basketball team will pay is $165.

2. The change that the person will recieve after paying is $43.075

1. The basketball team went out and the total bill was $125.

Tip given to waitress= 25% = 25% × $125 = $31.25

Tax rate = 7% = 7% × $125 = $8.75

Total bill = $125 + $31.25 + $8.75 = $165

2. Amount saved = $100

Total bill = $45

Tip given to waitress= 20% = 20% × $45 = $9

Tax rate = 6.5% = 6.5% × $45 = $2.925

Answer:

1024

Step-by-step explanation:

4^5

= 4*4*4*4*4

= 16*4*4*4

= 64*4*4

= 256*4

= 1024

Using the addition, if you buy 3.16 pounds or oranges, 1.15 pounds of peaches and 2.24 pounds of apples , then the total bill is 6.55 pounds

The cost of the oranges = 3.16 pounds

The cost of the peaches = 1.15 pounds

The cost of the apples = 2.24 pounds

Then the total bill = The cost of the oranges + The cost of the peaches + The cost of the apples

Here we have to use the addition

Substitute the values in the equation

Then the total bill = 3.16 + 1.15 + 2.24

= 6.55 pounds

Hence, using the addition, if you buy 3.16 pounds or oranges, 1.15 pounds of peaches and 2.24 pounds of apples , then the total bill is 6.55 pounds

Answer:

y=-1

y=43

x=14

Step-by-step explanation:

So, you have the equation: [tex]y=-4x+15[/tex], and if we know one value we can easily solve for the other using some algebraic manipulation.

Find y when x=4.

For this we know one value, "x", and the other "y" value is unknown. This is actually not to hard if you notice that the equation we're given expresses the value of "y" in terms of "x".

So let's plug in the x-value: [tex]y=-4(4)+15\implies y=-16+15=-1[/tex]

So we get: y=-1, which turns out to be the solution!

Find y when x=-7

This is a similar process, so let's just get straight into it and plug x as -7

[tex]y=-4(-7)+15\\y=28+15\\y=43[/tex]

This is our solution, y=43

Find x when y = -41

So this case is a bit different since we're given the y-value and not the x-value, and as I mentioned the equation represents the value of y in terms of x.

We still do a similar process, except we'll use some more algebraic manipulation, but let's start by plugging in the known value:

[tex]-41=-4x+15[/tex]

Let's move the constant, 15, to the other side by subtracting by 15 to cancel both sides.

[tex]-56 = -4x[/tex]

Now we want to get the x alone, and the only "operation" being done on the x, is that it's being multiplied by the coefficient of -4. To cancel this out we want to divide both sides by -4 to maintain equality & cancel out the coefficient of -4 to one, which is just 1 * x which can be expressed as x as it's implied the coefficient is 1

[tex]14=x[/tex]

Now we have our solution!

By using the concepts of recurrence formula and sum, the sum of the first 26 terms of the sequence is equal to 299.

In this problem we have a recurrence formula of the following form: a₁ = C and aₙ = aₙ₋₁ + k. Then, the sum of first n terms of the sequence is:

s = a₁ + a₂ + a₃ + ... + aₙ₋₁ + aₙ

First, determine the first 26 terms of the series:

a₁ = 49

a₂ = 46

a₃ = 43

a₄ = 40

a₅ = 37

a₆ = 34

a₇ = 31

a₈ = 28

a₉ = 25

a₁₀ = 22

a₁₁ = 19

a₁₂ = 16

a₁₃ = 13

a₁₄ = 10

a₁₅ = 7

a₁₆ = 4

a₁₇ = 1

a₁₈ = - 2

a₁₉ = - 5

a₂₀ = - 8

a₂₁ = - 11

a₂₂ = - 14

a₂₃ = - 17

a₂₄ = - 20

a₂₅ = - 23

a₂₆ = - 26

Second, sum all the terms found in the previous step:

s = 49 + 46 + 43 + 40 + 37 + 34 + 31 + 28 + 25 + 22 + 19 + 16 + 13 + 10 + 7 + 4 + 1 - 2 - 5 - 8 - 11 - 14 - 17 - 20 - 23 - 26

s = 299

The sum of the first 26 terms of the sequence is equal to 299.

A Venn diagram is visual representation that makes use of circles to highlight the connections between different objects or limited groups of objects. Circles that overlap share certain characteristics, whereas  the circles that do not overlap do not.

Venn diagrams are useful for showing how the two concepts are related and different visually. They have long been acknowledged for their value as teaching resources. Venn diagrams have been incorporated into elementary-level lesson plans and the introduction to logic curricula worldwide since the middle of the 20th century.

Venn diagrams are helpful for displaying the relationships between several ideas or factors. They can quickly demonstrate how things are alike or dissimilar as well as where and how they overlap. A Venn diagram's center, which is where two or more circles intersect, frequently indicates some nexus or central concept that may be broken down into the various other circles, with the labels on the outer portions representing more abstract and separate concepts than those near the center.

Since, BUC= {1,2,3,5,7,8}

(3, 8); (x, y) → (y + 1, x + 1)

We know that in transformation, it could either be a reflection, a dilation, a translation e.t.c.

Now, let us look at the shapes A and B to find their coordinates.

Coordinates of Shape A are; (1, 6), (5, 6), (3, 8)

Coordinates of Shape B are; (7, 6), (7, 2), (9, 4)

Since the transformed shape B is to the right of the original shape A, then we can suggest that the first transformation is a reflection about the line x = 6. Thus, this is; (x, y) → (y, x)

The transformation of shape A following (x, y) → (y, x) is;

A'(6, 1), B'(6, 5), C'(8, 3)

Comparing that to the coordinates of shape B, we can say that the transformations are;

(1, 6);  (x, y) → (y + 1, x + 5)

The temperature in Celsius (C) increased by 273.15 to get the temperature in Kelvin (K). The equation with the subject Celsius (C) is C=K-273.15, Option A correct.

Given that,

The temperature in Celsius (C) increased by 273.15 to get the temperature in Kelvin (K).

The formula K = C + 273.15 can be used to simulate this.

We have to find the equation with the subject C.

K=C+273.15

Taking the C to left hand side and K to right hand side.

-C=273.15-K
