Answer:

$165

Step-by-step explanation:

Cost of dinner = $132

Sales tax = 10% of dinner cost

Tip left = 15% of dinner cost

Amount of sales tax :

10% of $132

0.1 * $132 = $13.2

Amount of tip left :

15% * $132

0.15 * $132 = $19.8

Total cost of dinner :

Dinner cost + sales tax + tip

$132 + $13.2 + $19.8

= $165

Step-by-step explanation:

Given the function y = x²+12x

We are to find the inverse and identify the error in the calculation:

Step 1: Replace y with x

x = y²+12y

First Error: There is an error here y, the variable attached to x should be y and not x that is y =  y²+12y and not y = y²+12x. The x should be totally replaced with

The second error is where he wrote y = √-11x

The square root of a value must return both negative and positive value not only the positive value. Hence the correct expression should have been y = ±√-11x (Note that the sign ± was introduced)

Third error: Since the value inside the square rot is a negative value hence the value of x must be negative i.e x must be less than zero not greater then. The correct inequality expression should have been x <0 and not

x< 0

Answer:

DCB=50 degree (sum of interior angle of quadrilateral)

Answer:

Slope = 4 and y-intercept = 1

Step-by-step explanation:

→ To find the slope, look at the value before the x

4

→ To find the y-intercept, make x = 0 then the answer is the y-intercept

1

Answer:

X=-1/4 or y=1

Step-by-step explanation:

0=4x+1

-4x=1x=-1/4

y=4×0+1

y=1

4^3

you can write it like 4 × 4 × 4

you can also call it "Four to the Third power". or "Four cubed".

Yes you can. here is the answer and explanation

Answer:

They spent $600 on costumes.

Step-by-step explanation:

10% = $800 ÷ 10 = $80

20% = $80 x 2 = $160

50% = $800 ÷ 2 = $400

5% = $80 ÷ 2 = $40

400 + 160 + 40 = $600

Answer:

Angle k= 105

Angle n= 40

Angle m= 65

Answer:

m∡k = 105°

m∡n = 40°

m∡m = 65°

Step-by-step explanation:

m∡k = 105° because this angle forms a linear pair with a 75° angle

m∡n = 40° because this angle forms a linear pair with a 140° angle

m∡m = 65° because there are 180° in a triangle and one angle is 75° and the other angle is a vertical angle to angle 'n' which means they are equal

Answer:

n = 18

Step-by-step explanation:

(2n) and (n + 18) are vertically opposite angles and are congruent, then

2n = n + 18 ( subtract n from both sides )

Answer:

4 ampers

Step-by-step explanation:

WHEN 12 VOLTS ARE APPLIED, THE CURRENT IS 4 AMPERES.

The current when 29 volts are applied is; 4.14 amperes.

According to the question;

The electric current I, in amperes, in a circuit varies directly as the voltage V.

In essence;

I/V = constant.

Therefore;

I1/V1 = I2/V2

where;

Therefore; we have;

By cross product;

I2 = 4.14 amperes.

In conclusion, the current when 29V voltage is applied is; 4.14 amperes.

Step-by-step explanation:

We have found the value of each variable as a = 17, b = 34, c = 17 and d = 17√3. We can use trigonometric functions to find the answer.

Trigonometric functions are the ratios existing between the sides of a right-angled triangle. These ratios are constant for every right-angled triangle.

The sine of any angle is given by opposite side/hypotenuse.

The cosine of any angle is given by the adjacent side/hypotenuse.

We can find the value of a using sin 45:

sin 45 = 1/√2

⇒ a/17√2 = 1/√2

⇒ a/17 = 1

⇒ a = 17

We can find the value of c using cos 45:

cos 45 = 1/√2

⇒ c/17√2 = 1/√2

⇒ c/17 = 1

⇒ c = 17

We can find the value of b using sin 30:

sin 30 = 1/2

⇒ a/b = 1/2

Substitute the value of a:

17/b = 1/2

⇒ b = 34

Now we can use cos 30 to find the value of d:

cos 30 = √3/2

⇒ d/b = √3/2

Substitute the value of b:

d/34 = √3/2

⇒ d = 34*√3/2

⇒ d = 17√3

Therefore, We have found the value of each variable as a = 17, b = 34, c = 17 and d = 17√3.

Answer:

433.5 cm²

Step-by-step explanation:

The formula for circumference is C = 2πr, where r is the radius.

Here, C = 2πr = 73.79 cm.  Solving this for the radius, r, we get:

     73.79 cm

r = ---------------- = 11.75 cm

        2(3.14)

Then the area of the hubcap is A = πr², or, in this case,

A = 3.14(11.75 cm)²  =  433.5 cm²
