Answer:

Cashier scanned the bread twice.

Step-by-step explanation:

= 2.49 + 2.19 + 1.47 + 0.87 = 7.02

= 7.02 + 0.75 = 7.77

= 7.77 + 0.04 = 7.81

With 2 dollars and 19 cents leftover, even if the pennies were changed to dimes, youd still have only get up to 8.17 which still leaves 1 dollar and 83 cents leftover.

With that eliminated what could have the cashier miss-scanned? The paper towels are incorrect because 1.47 + 7.81 doesnt make 10 dollars

The dishwashing liquid isn't right either, because 0.87 + 7.81 doesn't make 10 dollars aswell.

The milk is also incorrect because 2.49 + 7.81 doesnt make EXACTLY 10 dollars. The bread is to correct answer bevause 2.19 + 7.81 equals exactly 10 dollars.

Hope this helps :)

Answer:

I think the answer would be A) If two angles are equal in a triangle, then the sides opposite are equal.

Step-by-step explanation:

I hope this helps, have a nice day :]

AB = BC

AC is the opposite side of ∠2.

BC is the opposite side of ∠1.

Opposite sides of equal angles are equal.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

∠3 = ∠1

From the figure, we see that,

∠3 and ∠2 are vertical angles.

Vertical angles are equal.

Now,

∠2 = ∠1

AC is the side opposite to ∠2.

BC is the side opposite to ∠1.

The sides that are opposite to equal angles are also equal.

Thus,

AC and BC are equal.

Answer:

Yes, x = 33 is a solution

Step-by-step explanation:

To see if it is a solution, plug in 33 as x

3 = x/11

3 = 33/11

3 = 3

Since this is correct, x = 33 is a solution.

Given,

The value of x is 33.

[tex] \implies \: 3 = \bf\dfrac{x}{11} [/tex]

[tex] \implies \: 3 \times 11 = \bf x[/tex]

Putting the value of x ..

[tex] \implies \: 33 = 33[/tex]

Left hand side is equal to right hand side, it means that x = 33 is a solution of given equation.

Answer: The area of the parallelogram ABCD = 32.4 sq. cm

Step-by-step explanation:

Given: In parallelogram ABCD, AB = 7.2 cm and the perpendicular drawn from C (altitude) on AB is 4.5 cm i.e.e height =4.5 cm.

Area of parallelogram = [tex](Base \times height)[/tex]

Then, Area of parallelogram ABCD = [tex]7.2\times4.5[/tex]

= [tex]32.4\ cm^2[/tex]

Therefore , the area of the parallelogram ABCD = 32.4 sq. cm

Step-by-step explanation:

Answer:

AC = 40

Step-by-step explanation:

A quadrilateral is a polygon shape with four sides and four angles. The interior angle of a quadrilateral sums up to 360°.

A parallelogram is a quadrilateral (has four sides and four angles) in which has two pair of opposite sides are parallel to each other. The diagonals of a parallelogram bisect each other.

Given parallelogram ABCD:

Diagonals AC and BD bisect each other at point E. Hence:

AC = AE + CE (line segment addition postulate)

Also:

AE = CE (diagonal BD bisects AC at point E).

Hence; x + 16 = 5x

5x - x = 16

4x = 16

x = 4

AE = x + 16 = 4 + 16 = 20; CE= 5x = 5(4) = 20

AC = AE + CE = 20+ 20 = 40

Step-by-step explanation:

Answer:

There are no solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

5(3x+9)−2x=15x−2(x−5)

Step 1: Simplify both sides of the equation.

5(3x+9)−2x=15x−2(x−5)

(5)(3x)+(5)(9)+−2x=15x+(−2)(x)+(−2)(−5)(Distribute)

15x+45+−2x=15x+−2x+10

(15x+−2x)+(45)=(15x+−2x)+(10)(Combine Like Terms)

13x+45=13x+10

13x+45=13x+10

Step 2: Subtract 13x from both sides.

13x+45−13x=13x+10−13x

45=10

Step 3: Subtract 45 from both sides.

45−45=10−45

Answer:

The equation of the line  that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3 will be:

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

Given the line

y=2/5x+3

comparing with the  slope-intercept form of the line equation

Thus, the slope of the line is: m = 2/5

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:  

slope = m = 2/5

Thus, the slope of the the new perpendicular line = – 1/m = [-1]/[2/5] = -5/2

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the slope of perpendicular line m = -5/2 and the point (4, 3)

[tex]y-3=-\frac{5}{2}\left(x-4\right)[/tex]

Add 3 to both sides

[tex]y-3+3=-\frac{5}{2}\left(x-4\right)+3[/tex]

[tex]y=-\frac{5}{2}x+13[/tex]

Therefore, the equation of the line  that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3 will be:

Answer:

Essentially, slope is rise/run. Rise is how many units up the graph, and run is how far to the left or right it goes. Rise will be negative if it's going down, and run will be negative if it's going left. There's two ways to find the slope in this case.

1. Stick to the more visual aspect of it, and count how many units up from one point to the next point. Point (1,2) is 2 units up from point (0,0). Then you count how many units right or left it goes. In this case, it's 1 towards the right. This means the rise/run comes out to be 2/1, which means the slope=2.

2. Look at the equations. y=mx+b is the linear format for these lines. y is the y coordinate, m is the slope, x is the x coordinate, and b is the y intercept (the point where x=0). These two lines have shared slope values, which means the slope for both of them is 2.
