Answer:

Answer:

$247.37

Step-by-step explanation:

The total dinner bill with a tip for the large party is $177.90.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

The gratuity for a large party is 20% of the bill, so we can calculate the gratuity by multiplying the bill by 0.2.

Gratuity = bill x 0.2

Gratuity = 148.25 x 0.2

Apply the multiplication operation, and we get

Gratuity = 29.65

To find the total bill, we add the gratuity to the original bill.

Total bill = bill + gratuity

Total bill = 148.25 + 29.65

Apply the addition operation, and we get

Total bill = $177.90

Hence, the total dinner bill with a tip for the large party is $177.90.

Answer:

x = -4 (and btw that is so cuteee)

Step-by-step explanation:

Points: (-4,-1) and (-4,-5)

m = y2 - y1/x2 - x1

m = (-5) - (-1)/(-4) - (-4)

m = -5 + 1/-4 + 4

m = -4/0

x = - 4

x not y ;w;

Answer:

y = -x +6

Step-by-step explanation:

i honestly didn't know what form you wanted so i put it in slope-intercept form for you :D

formula for slop-intercept form:

y=mx+b

12 = -1 ( -6 ) + b          -----> filled in the m, x and y

12 = 6 + b                   -----> do PEMDAS

12 - 6 = b                    -----> moved 6 to the other side to isolate variable

6 = b                           -----> you found the y-intercept

y = -x + 6                    ------> fill the equation in :D

Answer:

Your answer to your question is 15

Step-by-step explanation:

Note: Cost of second iron must be 1200 instead of 12000.

Given:

Cost of first electric iron = 900

Grain on first electric iron = 10%

Cost of second electric iron = 1200

Loss on second electric iron = 5%

To find:

The correct statement for the given problem.

Solution:

We have,

Cost of first electric iron = 900

Grain on first electric iron = 10%

Profit on first iron is

[tex]900\times \dfrac{10}{100}=90[/tex]

Cost of second electric iron = 1200

Loss on second electric iron = 5%

Loss of second iron is

[tex]1200\times \dfrac{5}{100}=60[/tex]

Now, profit is 90 and loss is 60. Profit is more than loss.

Exact profit = Profit - Loss

Exact profit = 90 - 60

Exact profit = 30

Therefore, Avinash get a profit of Rs. 30 on the transactions. Hence, the correct option is c.

Answer:

B

Step-by-step explanation:

Plug the coordinates in the answer choices to see if they give you 18.

Option A:  5(5) - 2(3) = 25- 6 = 9. Not it

Option B: 5(4) - 2(1) = 20 - 2 = 18. Works.

It has to be B because we've already tested (5,3) in option A and it wasn't correct.

Answer:

The options are not shown, so i will answer in a general way.

First, for a line of the form:

y = a*x + b

All the perpendicular lines will have a slope of -(1/a), then we can write a general perpendicular line as:

y = -(1/a)*x + c.

In this problem we have the perpendicular lines:

y=(s/t)*x+10

y = (q/r)*x - 4

Because those lines are perpendicular, we must have that:

(q/r) = -(1/(s/t)) = -(t/s)

q/r = -t/s

and we knew that s, t, q and r are integers (where t and r can not be equal to zero), and because of this relation, where we can see that in the denominator at the right we have the integer s, we can conclude that s can not be zero (we can not divide by zero).

And we know that t and s are both different than zero, then:

-t/s ≠ 0.

This means that:

q/r ≠ 0

And from this, we can conclude that q is different than zero.

Step-by-step explanation:

Simplify (x3 +  3x2 + 5x – 4) –  (3x3 – 8x2 – 5x + 6)

The first thing I have to do is take that "minus" sign through the parentheses containing the second polynomial. Some students find it helpful to put a "1" in front of the parentheses, to help them keep track of the minus sign.

Here's what the subtraction looks like, when working horizontally:

(x3 + 3x2 + 5x – 4) – (3x3 – 8x2 – 5x + 6)

(x3 + 3x2 + 5x – 4) – 1(3x3 – 8x2 – 5x + 6)

(x3 + 3x2 + 5x – 4) – 1(3x3) – 1 (–8x2) – 1(–5x) – 1(6)

x3 + 3x2 + 5x – 4 – 3x3 + 8x2 + 5x – 6

x3 – 3x3 + 3x2 + 8x2 + 5x + 5x – 4 – 6

–2x3 + 11x2 + 10x –10

And here's what the subtraction looks like, when going vertically:

−(3x

​

+3x

​

+5x

​

​

​

In the horizontal addition (above), you may have noticed that running the negative through the parentheses changed the sign on each and every term inside those parentheses. The shortcut when working vertically is to not bother writing in the subtaction sign or the parentheses; instead, write the second polynomial in the second row, and then just flip all the signs in that row, "plus" to "minus" and "minus" to "plus".

The commission of the salesmen with the given ratio will be $175.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

The commission is $100 for $1000 in sales.

Ratio of commission to sales = 100/1000 = 0.1

With the same ratio,

Commission/1750 = 0.1

Commission = 1750 x 0.1 = $175

Hence "The commission of the salesmen with the given ratio will be $175".

Step-by-step explanation:

Assuming you require the distance between the 2 points.

To calculate the distance d use the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 3, - 8) and (x₂, y₂ ) = (- 2, - 3)

d = [tex]\sqrt{(-2+3)^2+(-3+8)^2}[/tex]

   = [tex]\sqrt{1+25}[/tex]

   = [tex]\sqrt{26}[/tex] → A

Answer:

9n+13

Step-by-step explanation:

The perimeter is adding the entire pentagon together, so 2n+2n+(n+5)+(n+5)+(3n+3). When you combine like terms, it becomes 9n+13.

Answer:

Perimeter of the given figure is :---

[tex](2n) + (2n) +( n + 5) + (n + 5) + (3n + 3) \\ = 2n + 2n + n + 5 + n + 5 + 3n + 3 \\ = \boxed{9n + 13}✓[/tex]
