Calculate the total amount for the top problem

Hourly wage: $4.25 times the number of hours worked: 9

$38.25. Now add the tips made with the amount earned after working 9 hours

+51.85 = $90.10

Finding the percent tipped on the bottom problem

$18.50 times 0.14 (14%) = $2.59

6.)
(9 × 4.25) + 51.85. Rate times time = Pay then add the rip
38.25 + 51.85
$90.10

7.)
(2.59/18.50)×100 part/whole gives you percentage as a decimal then multiply by 100 to get an actual percent.
0.14 × 100
14%
Hope this helps!

Each of two vectors, and , lies along a coordinate axis in the xy plane. Each vector has its tail at the origin, and the dot pro
ladessa [460]

Answer:

A lies along the positive x-axis and B lies along negative x - axis .

Step-by-step explanation:

They tell us that we have two vectors, A and B. And they give us a series of conditions for this, now, what would be the correct possibility.

A lies along the positive x-axis and B lies along negative x - axis .

This is because when both vectors will be in x axis but opposite to each other, then the angle between them will be 180 ° and cos180 ° is -1.

2. Which diagram shows a point P an equal distance from points A, B, and C?H
amm1812

Answer:

The correct option is (a).

Step-by-step explanation:

The vertices are equidistant from the circumcenter.

Circumcenter of a triangle is a point where the perpendicular bisectors are intersection each other.

In figure (a) the point P is the intersection point of all perpendicular bisector, therefore point P is the circumcenter of triangle ABC and the point P is equidistant from A,B and C.

Therefore option (a) is correct.

In figure (b) the point P is the intersection point of all perpendicular, therefore point P is not the circumcenter of triangle ABC.

Therefore option (b) is incorrect.

In figure (c) the point P is the intersection point of all bisectors, therefore point P is not the circumcenter of triangle ABC.

Therefore option (c) is incorrect.

In figure (d) the point P is the intersection point of all medians, therefore point P is not the circumcenter of triangle ABC.

Therefore option (d) is incorrect.

10. Write (2x + 1)(x - 3)(x - 2) in standard form.
Leto [7]

Answer:

2x^3-9x^2+7x+6

Step-by-step explanation:

The standard form of a polynomial is a method of writing a polynomial such that the terms are organized by degrees. In essence, the first term, or the left-most term has the highest degree or largest exponent. The right-most term or last term has the lowest degree or smallest exponent. One is given an expression in factored form. Distribute, multiply every term by another in the parenthesis, then simplify. Repeat this process until there are no more factored terms. Finally, rewrite the expression in standard form.

(2x+1)(x-3)(x-2)

Distribute,

(2x+1)(x-3)(x-2)

((2x)(x)+(-3)(2x)+(1)(x)+(1)(-3))(x-2)

Simplify,

((2x)(x)+(-3)(2x)+(1)(x)+(1)(-3))(x-2)

(2x^2-6x+x-3)(x-2)

(2x^2-5x-3)(x-2)

Distribute,

(2x^2-5x-3)(x-2)

(2x^2)(x)+(-5x)(x)+(-3)(x)+(-2)(2x^2)+(-2)(-5x)+(-3)(-2)

Simplify,

(2x^2)(x)+(-5x)(x)+(-3)(x)+(-2)(2x^2)+(-2)(-5x)+(-3)(-2)

2x^3-5x^2-3x-4x^2+10x+6

2x^3-9x^2+7x+6

This polynomial is already in standard form, thus there is no need to reorganize it. The leading term or the left-most term has the highest degree, three, the succeeding terms are in respective order of decreasing exponents.

(c ) Find the values of x and y in the vector equation (5÷3)+2(x÷y)-(1÷-7)=0​
german

Answer:

y= -21x/19 x≠0

Step-by-step explanation:

(I just reviewed this!) Combined like terms and used Pemdas for Order of Operations. Canceled out -21x with -21 and we know that x is not equal to 0. If you need more help there are some sites like Khan Academy.
