An item is priced at $13.51. If the sales tax is 7%, what does the item cost including sales tax? please help ‍♀️‍♀️

Answer:

71

Step-by-step explanation: 2x=142

x=71

Answer:

the missing angles are 71

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

142° is an exterior angle of the triangle, thus

x + x = 142

2x = 142 ( divide both sides by 2 )

x = 71

Answer:

0.09 and 0.04

Step-by-step explanation:

The probability that a randomly-selected person at a show has seen the band play live before is 30%=0.30

The probability that a person at a show is a "superfan" is 20%=0.20

Two people are selected at random.

The probability that both people have both seen the band perform live before  = The probability that the first person has seen the band live before and the second person also has seen the band live before.

=0.30 x 0.30

=0.09

Similarly, the probability that both are  "superfans"   = The probability that the first person is a superfan and the probability that the second person is a superfan.

=0.20 x 0.20

=0.04

Hence, the probability that both people have both seen the band perform live before, and are "superfans" are 0.09 and 0.04 respectively.

Answer:

7250

Step-by-step explanation:

This is like the pythagorean theorem. So you add A^2,B^2, and C^2. So 25^2 + 60^2 + 55^2. 625 + 3600 + 3025. That equals to 7250.

Answer:

37 degrees

Step-by-step explanation:

All insides of triangles = 180 degrees, so...

67 degrees + 76 degrees + (x + 48) degrees = 180

67 + 76 + (x + 48) = 180

143 + x + 48 = 180

191 + x = 180

x = -11

x + 48

-11 + 48

37 degrees

Answer:

The answer is 6 in reduced fraction form:)

Step-by-step explanation:

The reduced fraction of the given division is 6/1.

Given that, 78 divided by 13.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Here, 78/13

= 6/1

Therefore, the reduced fraction of the given division is 6/1.

Answer:

x=1/8

Step-by-step explanation:

First we need to isolate the variable. We can do that by subtracting 3 from each side. You then get: 24x-2=1. Then, to completely isolate it, add 2 to each side. We get 24x=3. Now divide 24 from each side to get only x. We get 3/24, which can be rewritten as 1/8.

Answer: x = 15

Step-by-step explanation:

1) Set q(x) = 3 in the equation.

3 = (4/5)x - 9

2) Add 9 to both sides.

12 = (4/5)x

3) Multiply by 5/4 on both sides.

15 = x

x = 15

Step-by-step explanation:

Answer:

No solution

Step-by-step explanation:

Any equations with the same slope are parallel, or will never intersect.

In a slope-intercept equation, this would mean the 'm' values are the same.

y = mx + b

Two equations:

y = 5x - 4

y = 5x - 5

Since the two equations given have the same slope, they will never intercept and therefore have no solution.

Answer:

The slope is -1.

Step-by-step explanation:

Slope= y2-y1/x2-x1 So slope =2-1/-4-(-3)= 1/-1. 1/-1= -1, so the slope= -1.

Answer: −y^2+18y

Let's simplify step-by-step.

Distribute:

=(5y)(4)+(5y)(−y)+(5y)(−2)+(4y)(y)+(4y)(2)

=20y+−5y2+−10y+4y2+8y

Combine Like Terms:

=20y+−5y2+−10y+4y2+8y

=(−5y2+4y2)+(20y+−10y+8y)

=−y^2+18y

Answer:

= −y^2+18y

Answer:

there are no x values of X that make the equation true

Step-by-step explanation:

The given equation is not the same on the left-hand side as on the right-hand side so there will be no solution or the equation is wrong.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

Given the equation

4x + 8 = 4x - 3

Subtract 4x from both sides

4x + 8 - 4x = 4x - 3 - 4x

(4x - 4x) + 8 = (4x - 4x) - 3

8 ≠ 3

Since it is not satisfying so it will not have any solution.

Hence "The given equation is not the same on the left-hand side as on the right-hand side so there will be no solution".
