PLEASE HELP PLEASEEEE!!! Number 3

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

These are like terms as they both have the same variables and powers

Answer:

65

Step-by-step explanation:

90 - 25 = 65

Complementary angles = angles that sum up to 90 degrees

Answer:

the measure of the angle that is a complement of angle C=90-25=65

65° is your answer

Answer:

Answer:

y = - 2x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2 , then

y = - 2x + c ← is the partial equation

To find c substitute (- 2, - 4) into the partial equation

- 4 = 4 + c ⇒ c = - 4 - 4 = - 8

y = - 2x - 8 ← equation of line

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:

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.

Answer:

oh sorry it's cuboid ithought I said square

Step-by-step explanation:

Answer:

See the explanations below

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

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

Step-by-step explanation:

The question is not complete, but I would show how to solve a similar question.

Joy recorded the distances she walked each day for five days. How far did she walk in 5 days?

Solution:

We can see that Joy distance is recorded in the dot plot. From the dot plot, we can see that she walked 1/3 miles each day for three days, 1/2 miles for one day and 2/3 miles for one day. Therefore, to get the total distance walked, we just have to sum the individual distance that she walked each day. Hence the total distance is given as:

[tex]Total \ distance=\frac{1}{3} +\frac{1}{3} +\frac{1}{3}+ \frac{1}{2}+ \frac{2}{3} =\frac{13}{6}=2\frac{1}{6}[/tex]

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
