Answer:

$513.34

Step-by-step explanation:

Mr. DeLuca used his debit card twice, each time for $27.50.  This is a total of $55 spent.

$27.50 × 2 = $55

You now have to subtract the money spent from his bank balance.

$568.34 - $55 = $513.34

$513.34 was left in his bank account.

Answer:

v > -1

Step-by-step explanation:

v satisfies both these inequalities:

(*) -17 + 4v < 10v - 11

(**) 10v - 11 < 11v + 6

(*) <=> -17 + 11 < 10v - 4v

<=> -6 < 6v or 6v > -6

<=> v > -1

(**) <=> -11 - 6 < 11v - 10v

<=> -17 < v or v > -17

Combine (*) and (**)

--> Solution for this inequality is v > -1

Answer:

(11/3, 4)

Step-by-step explanation:

To calculate the coordinates of the point that partitions the line segment in the given ratio, we shall be using the internal division formula.

Mathematically, that is ;

= {(mx2 + nx1/(m+n), (my2 + ny1)/(m + n)}

m and n represents the ratios 1:2

(x1, y1) represents the coordinates of A

(x2,y2) represents the coordinates of B

From the question, let’s list out the individual values;

m = 2

n = 1

x1 = 3

x2 = 4

y1 = 6

y2 = 3

Substituting these values in the equation, we have;

(2(4) + 1(3)/(1+2) , (2(3) + 1(6)/(1 + 2))

= (8 + 3)/3 , (6 + 6)/3)

= (11/3, 12/3)

= (11/3 , 4)

Answer:

19.25

Step-by-step explanation:

if it sells per pound you would just multiply by 7 because thats what your looking for

have a great day :)

Answer:

$19.25

Step-by-step explanation:

One lb of granola sells for $2.75. You are trying to find how much 7 pound costs. Multiply 2.75 with 7:

($2.75/1 lb of granola) x (7/7) = (2.75 * 7/7 lb of granola)

Simplify:

2.75 * 7 = 19.25

7 lbs of granola costs $19.25

Answer:

p = -1

Step-by-step explanation:

Step 1: Write out equation

-5 - 8p = -3p

Step 2: Add 8p to both sides

-5 = 5p

Step 3: Divide both sides by 5

-1 = p

Step 4: Rewrite

p = -1

Answer:

P=-1

Step-by-step explanation:

-5-8p=-3p

+8p +8p

------------------

-5=5p then divide both sides by 5

P=-1

Answer:

Graph D.

Step-by-step explanation:

Hey there!

A coefficient is the number being multiplied by the variable,

Example: 5x - 5 is a coefficient

Graph d has a negative slope meaning the slope would be,

-1, -2, -3, -4, -5, ect.

So graph D is correct.

Hope this helps :)

Answer:

The correct option is;

16 inches

Step-by-step explanation:

The parameters of the motion given are;

The diameter, D of the bicycle = 16 inches;

The distance the bike moves (forward) after the screw punctures the tire = 56·π inches

We note that the circumference of the bicycle = π·D = π × 16 = 16·π inches

Therefore;

56·π inches/(16·π inches) = 3.5

Showing that the bicycle moves three and half complete turns (revolution) where after each complete turn, the screw starts from the bottom of the tire.

The height, h of the screw in the final half turn is given by the relation;

h = A×cos(Bx - C) + D

A = Amplitude of the motion = Diameter/2 = 16/2 = 8

P = The period of the motion 2·π/B

B·x = The angle described by the motion = Half of one revolution = π = 180°

C = Phase shift = π

D = The midline = Diameter/2 = 8 inches

Therefore;

h = 8×cos(π - π) + 8 = 16 inches

After the bike moves forward another 56·π inches the height of the screw = 16 inches.

Answer:

16 inches

What do Steven Hawking and Thomas Edison have in common

- Both men made mathematics discoveries

- Both men made discoveries that were well-received

- both men created technological inventions

- Both men used observations in their field of study

Answer:

- Both men made discoveries that were well-received

Step-by-step explanation:

Stephen Hawking and Thomas Edison were two great physicist or scientists, whose discoveries were well-recieved by all over the world.

Stephen Hawking gave theories in cosmology such as black holes that includes the second law, that states that black hole will never reduce its shape.

Thomas Edison was one of the great inventors in the history in different feilds such as mass communication, electric power generation, motion pictures, and sound recording. some of the inventions include Automatic Telegraph and tin foil phonograph.

They both have given scientific research and logics for their discoveries and so people accepted them.

Hence, the correct answer is " Both men made discoveries that were well-received ".

The answer is:

Answer:

y+z=x

Step-by-step explanation:

we know that

The Exterior Angle Property of a Triangle states that the measure of exterior angle of a triangle is equals to the sum of measures of its interior opposite angles

In this problem

Angle y and angle z are interior angles of triangle ABC and angle x is a exterior angle of triangle ABC

therefore

Applying the Exterior Angle Property of a Triangle

y+z=x

Answer:

The correct answer is x = 6.

Step-by-step explanation:

To solve this problem, we first must recognize that DE + EF = DF.

From this information, we can set up the following equation when we substitute in the given values:

DE + EF = DF

(4x-1) + 9 = 9x - 22

Our first step is going to be to combine like terms on the left side of the equation.  This is modeled below:

4x - 1 + 9 = 9x - 22

4x + 8 = 9x - 22

Then, we should subtract 4x from both sides of the equation.

8 = 5x - 22

Now, we can add 22 to both sides of the equation.

30 = 5x

Finally, we can divide both sides by 5.

x = 6

Therefore, the correct answer is x = 6.

Hope this helps!

================================================

Explanation:

x is a variable or placeholder for a number. Think of it like a box.

1x = 1 box

2x = 2 boxes

and so on

9x = 9 boxes

5x = 5 boxes

9x+5x = 9 boxes + 5 boxes = 14 boxes = 14x

So that's one way to see how 9x+5x = 14x.

Or you could add the coefficients 9 and 5 to get 9+5 = 14. Then tack an x onto everything.

----------

The y terms are handled in a similar fashion.

-5y + 9y = 4y

which is the same as

9y - 5y = 4y

You could think of it like this

(9 yaks) - (5 yaks) = 4 yaks

So we started with 9 yaks and took away 5 of them to be left with 4 yaks.

----------

After getting the results 14x and 4y. We would then have the final answer 14x+4y

The x and y terms cannot be combined since they are not like terms. So we leave that expression as is.

Answer:

The Elegant Home Architects charges are less than Rock the House Digital Designs charges for hours worked more than 2.

If the number of hours worked is equal to 2 than both would charge the same and if the hours are less than 2 then  Rock the House Digital Designs  will be a better option .

Step-by-step explanation:

Let ℎ represent the number of hours for which the Johnson family hires the design firm.

Suppose the  Johnson family hires the design firm for ten hours so h= 10

Then the charges by the Rock the House Digital Designs will be

$ 500 + 50(10)= $ 500+ $500= $1000

And the charges for the services by Elegant Home Architects will be

$75.00(10) = $ 750

Therefore the Elegant Home Architects charges are less than Rock the House Digital Designs charges.

But if the number of hours worked is equal to 2 than both would charge the same and if the hours are less than 2 then  Rock the House Digital Designs  will be a better option .

Rock the House Digital Designs

For 2 hours

$ 500 + 50(2)= $300

For 1 Hour

$500 + 50 (1)= $ 550

Elegant Home Architects

For 2 hours

$75.00(2) = $ 300

For 1 Hour

$75.00(1) = $ 75

Answer:

The order of the matrix D^T × (BE) is 2 × 4

Step-by-step explanation:

In the multiplication of matrix, the number of columns in the first matrix must be equal to the number of rows of the second matrix. The resulting matrix from the product will have the same number of rows as the first matrix and the same number of column as the second matrix. For example, given Matrix A of order (m × n) and Matrix Z of order ( n × k), the product of the two matrices will give a matrix ( say Y) of order (m × k).

AZ = Y

(m x n)(n x k) = (m x k)

Now, From the question,

The order of Matrix B is 4 × 5,

the order of the matrix D is 4 × 2

and the order of the matrix E is 5 × 4.

To determine the order of the matrix D^T × (BE)

First, will find the order of (BE)

Order of BE = (4 × 5) (5 × 4)

Order of BE = (4 × 4)

Hence, the order of matrix (BE) is 4 × 4.

Now, we will determine the order of matrix D^T

D^T means the transpose of matrix D.

The transpose of a matrix is defined as a new matrix whose rows are the columns of the original matrix and the columns of the new matrix are the rows of the original matrix. This means given Matrix A of order (m × n), the transpose of Matrix A (A^T) will have an order of (n × m).

The order of the matrix D is 4 × 2

Hence, the order of the transpose of matrix D (D^T) will be 2 × 4

Now, the order of the matrix D^T × (BE) will be

Order of the matrix D^T × (BE) = (2 × 4) × (4 × 4)

Order of the matrix D^T × (BE) = 2 × 4

Hence, the order of the matrix D^T × (BE) is 2 × 4.
