Based on the cost of the calculator, the discount, the shipping fee, and the tax, the total cost of the purchase was a. $80.07

The cost of the calculator was:

= Cost of calculator x ( 1  - discount)

= 83 x ( 1 - 15%)

= $70.55

The sales tax would be:

= 70.55 x 4.5%

= $3.17

The total cost would be:

= Cost + Sales tax + Shipping fee

= 70.55 + 3.17 + 6.35

= $80.07

In conclusion, the total is $80.07.

Answer:

To prove: The equation x2+px−1=0 has real and distinct roots for all real values of p.

Consider x2+px−1=0

Discriminant D=p2−4(1)(−1)=p2+4

We know p2≥0 for all values of p

⇒p2+4≥0 (since 4>0)

Therefore D≥0

Hence the equation x2+px−1=0 has real and distinct roots for all real values of p

Answer:

-20

Step-by-step explanation:

[tex]5 * (-6 / -1+ -10)[/tex]

According to PEMDAS, we need to do the math in the parentheses first.

[tex]-6 / -1 + -10[/tex]

Applying PEMDAS to the inside of the parentheses, then we have to divide -6 by -1, where we would get 6.

[tex]6 + -10[/tex]

Adding a negative is the same as subtracting, so adding negative 10 is the same as subtracting 10.

[tex]6 - 10[/tex]

Subtracting, we get 6 - 10 = -4 and we're left with:

[tex]5 * (-4)[/tex]

Multiplying, our final answer is -20.

Hope this helps!

Step-by-step explanation:

The expression for the Perimeter of rectangle is 16w-4.

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Perimeter of the rectangle = 2(length+width)

Given the paramters are;

length  = 5w-2

width = 3w

Perimeter of the rectangle = 2(length+width)

Perimeter = 3w+3w+(5w-2)+(5w-2)

= 6w+10w-4

= 16w-4

The required change in the price of the share of stock is $4.4.

Given that,
On September 1, you own 12.5 shares of stock that are worth $149.87. On December 1, the shares are worth $94.87, and the change in the price per share of stock is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Initial total cost shares of stock = $149.87
A total number of shares = 12.5
The initial cost of single share = 149.87/ 12.5 = $11.98
Now final cost of the total share = $94.87
The final cost of the single share is = 94.87 / 12.5 = $7.58
Change in price of shares of stock = 11.98 - 7.58 = $4.4

Thus, the required change in the price of the share of stock is $4.4.

The number of cats and dogs the doctor saw is 56.

Ratio expresses the relationship between two values. It shows the frequency that one value is contained another value. The sign of ratio is :.

The equation that can be used to determine the total number of dogs that the doctor saw is:

(ratio of dog / total number of dogs and cats) x total number of animals = number of dogs

5/7 x a = 40

Where a is the total number of dogs and cats

In order to determine the value of a, divide both sides of the equation by 7/5.

40 x 7/5 = 56

Step-by-step explanation:

Two triangles are similar so we can use the similarity ratio to calculate the value of x this way we can find the length of FH

(x+8)/32 = (4x-25)/52 cross multiply expressions

52x + 416 = 128x - 800 export like terms to the same side of equation

416 + 800 = 128x - 52x

1216 = 76x divide both sides by 76

16 = x then the length of FH

4*16 - 25 = 39

If we had a sale price of 30% off of $1,050then the sale price is 70% of $1,050 or 0.7(1050) Then we add 7% sales tax to that making thefinal price paid 107% of [0.7(1050)] ... 1.07[0.7(1050)] = $786.45

Answer:

Let's solve for x.

x+y+z=8

Step 1: Add -y to both sides.

x+y+z+−y=8+−y

x+z=−y+8

Step 2: Add -z to both sides.

x+z+−z=−y+8+−z

x=−y−z+8

Answer:

x=−y−z+8

Explanation:

The two expressions mentioned add to 86, to indicate the total number of hours for both jobs combined.

We multiply the number of hours by the wage per hour to get the amount earned per job.

Lastly, we add those two subtotals to get the grand total earned

7t + 12(86-t)

Optionally you can distribute the 12 through and combine like terms. I'll leave it like this because I think it's more descriptive to show the two amounts earned from each job.

If you wanted to simplify 7t+12(86-t), then you would get 1032-5t or -5t+1032

Answer:

Step-by-step explanation:

The slope intercept form of an equation of a line is y = mx + b, where m is the slope and b is the y-intercept (the value of y when x=0).

Since the slope is (1/2), we can write:

y = (1/2)x + b

We want a value of b such that it forces the line to go through point (-10,9).  Enter that point in the equation and solve for b:

y = (1/2)x + b

9 = (1/2)*(-10) + b

9 = -5 + b

b = 14

The eqyuation of a line with a slope of (1/2) and goes through point (-10,9) is:

y = (1/2)x + 14
