7:00PM For dinner, you decide to go out to eat at a restaurant with your significant other. The bill is $32.43, and you would like to leave a 20% tip for your waiter. What will the amount of the tip be and what is the final amount of your bill? Remember to round all values to the nearest cent.

Answers

Answer 1

Answer:

Tip amount: $6.49

Final amount of the bill: $38.92

Step-by-step explanation:

We need to calculate the tip amount which is 20% of $32.43.

Then we will add the tip amount to $32.43.

To find a percent of a number, change the percent to a decimal by dividing the percent by 100 and multiply by the number.

20% of $32.43 =

= 0.2 * $32.43

= $6.486

We round off the tip amount to the nearest cent, $6.49

The tip amount is $6.49

To find the final amount of the bill, we add the tip amount to the bill amount.

$32.43 + $6.49 = $38.92

Answer:

9 miles

Step-by-step explanation:

24$ divided by 4$ and that is 6 miles

6 + 3 is 9 miles

A rectangle’s base is 6 cm longer than its height. The rectangle’s area is 135 cm2. Find this rectangle’s dimensions. You must include units with your answers

Answers

Area of a rectangle  =  length x height

Area = 135

Height = X

Lenght = x +6

135 = x * x+6

Simplify:

135 = x^2 +6x

Subtract 135 from both sides:

x^2 + 6x - 135 = 0

Solve:

2 numbers when added need to equal 6 and when multiplied equal -135

x = 9 and x = -15

The height can't be a negative number so the height is 9

Length =  9 +6 = 15

Height = 9cm, Length = 15 cm

f(x)=40+4x+x^2 (e) What is the slope of the chord connecting the points (5, f (5)) and (5 + ∆x, f (5 + ∆x)), when ∆x = 5? Really confused on how to do this and what it means

Answers

Answer:

19

Step-by-step explanation:

So we have the function:

[tex]f(x)=40+4x+x^2[/tex]

And we want to find the slope of the chord that connects the points (5,f(5)) and (5+Δx, f(5+Δx)).

So first, find the two points.

1) (5,f(5))

Substitute in 5 for x:

[tex]f(x)=40+4x+x^2\\f(5)=40+4(5)+(5)^2[/tex]

Square and multiply:

[tex]f(5)=40+20+25[/tex]

Add:

[tex]f(5)=85[/tex]

So, our first point is (5,85)

2) (5+Δx, f(5+Δx))

Remove the Δx by substituting it with 5. Thus:

[tex](5+\Delta x,f(5+\Delta x))=(5+5,f(5+5))=(10,f(10))[/tex]

Now, substitute in 10 for x. Thus:

[tex]f(10)=40+4(10)+(10)^2[/tex]

Square and multiply:

[tex]f(10)=40+40+100[/tex]

Add:

[tex]f(10)=180[/tex]

So our second point is (10,180).

Now, just find the slope between (5,85) and (10,180) using the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (5,85) be x₁ and y₁ and let (10,180) be x₂ and y₂. Substitute:

[tex]m=\frac{180-85}{10-5}[/tex]

Subtract:

[tex]m=\frac{95}{5}[/tex]

Divide:

[tex]m=19[/tex]

So, the slope that connects the chord is 19.

And we are done :)

The perimeter of a rectangle is 36 feet. If the length is 13, find the width

Answers

Answer: 5 feet

Step-by-step explanation: To find the width of the rectangle,

start with the formula for the perimeter, shown below.

Perimeter = 2l + 2w

Since we know the perimeter is 36 and the

length is 13, we have 36 = 2(13) + 2w.

Simplifying on the right, we have 36 = 26 + 2w.

Not subtract 26 from both sides to get 10 = 2w.

Now divide both sides by 2 and 5 = w.

So the with is 5 feet.

Your answer is 5 because you have to divide

36 / 13 = ?


36 / 13 = 5

2x+2=-59 I need help I don’t know the answer

Answers

Answer:

x= -30.5

Step-by-step explanation:

In order to solve equations like this, we need to have all the x terms on one side, and all the other terms on the other side. For this equation so far, the x term (2x) is not alone (there is a +2) so we need to move the +2 to the other side to have x by itself. Whatever you do to one side of equation, you must also do to the other side to keep the equation equal. Therefore we can subtract 2 from both sides which moves the two to the other side while keeping the equation equal. In order to move a term to the other side, we must do the operation opposite to what the term has. E.g. +2 is adding 2, so to move it to the other side, we need to subtract 2.

2x +2 -2 = -59 -2

Which cancels out the 2 on the left side and gives us:

2x = -59-2

2x = -61

Then we just need to remove the 2.

In this case, this 2 is being multiplied to the x, so to move it, we will need to divide both sides by 2.

2x/2 = -61/2

which finally gives us:

x = -30.5

Hope this helped!

Hey There!! ~

The answer to this is: the upper bound for the length is [tex]21.5cm.[/tex] Lower and Upper Bounds

The lower bound is the smallest value that will round up to the approximate value.

The upper bound is the smallest value that will round up to the next approximate value.

Ex:- a mass of 70 kg, rounded to the nearest 10 kg, The upper bound is 75 kg, because 75 kg is the smallest mass that would round up to 80kg.

Here , A length is measured as 21cm correct to 2 significant figures. We need to find what is the upper bound for the length . let's find out:

As discussed above , upper bound for any number will be the smallest value in decimals which will round up to next integer value . So , for 21 :

⇒  [tex]21.5cm.[/tex]

21.5 cm on rounding off will give 22 cm . So , the upper bound for the length is [tex]21.5cm.[/tex]

Answers

Answer:

  86°

Step-by-step explanation:

If you draw a line segment AC, it forms the rest of right triangle ACB with the right angle at C. Then angle BAC is the complement of the given angle:

  ∠BAC = 90° -47° = 43°

The inscribed angle BAC intercepts arc BC, so the arc measure will be double the angle measure.

  arc BC = 2·43° = 86°

__

Another way to get there is to realize that arc BCA is 180°, because AB is a diameter. As above, arc AC will be double the measure of inscribed angle ABC, so arc AC has measure 94°.

  arc BC = arc ACB - arc AC

  arc BC = 180° -94°

  arc BC = 86°

Let u = 2i + j, v = i + j, and w = i - j. Find scalars a and b such that u= av + bw.

Answers

Answer:

1/2 and 3/2

Step-by-step explanation:

Given the expression u= av + bw where u = 2i + j, v = i + j, and w = i - j, to find the scalars a and b, we will first substitute the vectors into the expression given as shown;

u= av + bw

2i + j = a( i + j)+b(i-j)

open the parenthesis

2i + j = ai+aj+bi-bj

collect like terms at the right hand side of the equation

2i + j = ai+bi+aj-bj

2i + j = (a+b)i+(a-b)j

compare the coefficient of complex value i and j on both sides

a+b = 2 ............... 1

a-b = 1................. 2

solve the resulting equation simultaneously using elimination method

Subtract both equation from each other.

(a-a) +(b-(-b))= 2-1

0+2b = 1

b = 1/2

Substitue b = 1/2 into equation 2 to get a

From equation 2, a = 1+b

a = 1 + 1/2

b = 3/2

Hence the scalars a and b are 1/2 and 3/2 respectively

[tex]a=\frac{3}{2},b=\frac{1}{2}[/tex]

A complex number is of the form [tex]\boldsymbol{a+ib}[/tex] where [tex]a,b[/tex] are real numbers.

[tex]u=2i+j[/tex]

[tex]v=i+j[/tex]

[tex]w=i-j[/tex]

[tex]u=av+bw[/tex]

So,

[tex]2i+j=a(i+j)+b(i-j)[/tex]

[tex]2i+j=(a+b)i+(a-b)j[/tex]

Therefore,

[tex]2=a+b\\1=a-b[/tex]

Add these equations.

[tex]3=2a\\\frac{3}{2}=a[/tex]

So,

[tex]1=\frac{3}{2}-b\\\\b=\frac{3}{2}-1\\[/tex]

Answers

Answer: The filled out table is shown below in the attached image

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

Explanation:

The letters A through J are one way to fill out the table. Though there are other possible orders.

Start at letter A, which is from the fact we have 40 people total

Then move to letter B. This is the total number who like pasta (26)

We have C = A-B = 40-26 = 14 people who don't like pasta

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

Now move to cell D. This is the total who don't like netball, which is 21 people. There are E = A-D = 40-21 = 19 people who do like netball.

F = 4 is the number of people who don't like either thing (netball or pasta). So G = D-F = 21-4 = 17 people like pasta but don't like netball.

Of those people who like netball (E = 19), we have 9 who also like pasta. This is in cell H in the upper left corner. This means J = E-H = 19-9 = 10 people like netball but don't like pasta.

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

So we have these values

A = 40B = 26C = 14D = 21E = 19F = 4G = 17H = 9 J = 10
