Answer:

The fourth one is correct.

Step-by-step explanation:

To show the diagonals are congruent, calculate their lengths using the Distance Formula: d=(x2−x1)2+(y2−y1)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√.

Find the length of LN.

Substitute 0 for x1, 2 for y1, 0 for x2 and −2 for y2.

LN=(0−0)2+(−2−2)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√

=02+(−4)2‾‾‾‾‾‾‾‾‾‾√

=8‾√

Find the length of MO.

Substitute 2 for x1, 0 for y1, −2 for x2 and 0 for y2.

MO=(−2−2)2+(0−0)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√

=(−4)2+02‾‾‾‾‾‾‾‾‾‾√

=8‾√

Since LN=MO, by the definition of congruent line segments, LN=MO.

To show the diagonals are perpendicular, calculate their slopes using the Slope Formula: m=y2−y1x2−x1.

Find the slope of LN.

Substitute 0 for x1, 2 for y1, 0 for x2 and −2 for y2.

m1=−2−20−0=−40⇒m1 cannot be defined.

Find the slope of MO.

Substitute 2 for x1, 0 for y1, −2 for x2 and 0 for y2.

m2=0−0−2−2

=0−4

=0

The slope of LN cannot be defined, this means that LN is parallel to y-axis. The slope of MO is equal to 0, this means that MO is parallel to x-axis. x and y axis are perpendicular, therefore LN⊥MO.

The figure shows the same square L M N O on a Cartesian plane as in the beginning of the task. Diagonal L N is perpendicular to diagonal M O.

To show the diagonals bisect each other, calculate their midpoints using the Midpoint Formula: P(x1+x22,y1+y22).

Find the midpoint of LN.

Substitute 0 for x1, 2 for y1, 0 for x2 and −2 for y2.

P1(0+02,2+(−2)2)=(0, 0)

Find the midpoint of MO.

Substitute 2 for x1, 0 for y1, −2 for x2 and 0 for y2.

P2(2+(−2)2,0+02)=(0, 0)

Both midpoints are the same point on the coordinate plane. This means the two diagonals intersect at their midpoints, or bisect each other.

The figure shows the same square L M N O on a Cartesian plane as in the beginning of the task. The diagonals intersect at point P. Segments L P, P N, M P, and P O are congruent.

Therefore, the diagonals are congruent perpendicular bisectors of each other.

Answer:

The answer is A = 14 B = 4  14 - 4 = 10 I think.

Step-by-step explanation:

It's not a sum its a difference because this is a subtraction problem I think.

Answer: The numbers in order from least to greatest is as follows:

-4/5

-0.75

-16

-8%

Hint: To better help you understand... -4/5 would be the least and -8% would be the greatest.

Answer:

x = - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Given

4x - 6 = 10x - 3 ( subtract 10x from both sides )

- 6x - 6 = - 3 ( add 6 to both sides )

- 6x = 3 ( divide both sides by - 6 )

x = [tex]\frac{3}{-6}[/tex] = - [tex]\frac{1}{2}[/tex]

Answer:

0.00475

Step-by-step explanation:

Answer:

17/50.

Step-by-step explanation:

If we convert 3 2/5 into an improper fraction, we get 17/5.

If you don't read the question carefully, it's easy to think that the answer would be 17/5 ÷ 9. However, this is wrong.

The question says "her AND her 9 friends," so there are 9+1=10 people total.

Thus, the answer would be

17/5 ÷ 10 = 17/5 * 1/10 = 17/50.

Answer:

B: 8^3 in squared

Step-by-step explanation:

2^3 = 2*2*2= 8

4^3 =4*4*4=64

Area of rectangle equals length times width.

So, 8 * 64 equals 512 and 8^3= 512

Use calculator. Also, you can just treat it as normal multiplication and choose the one with the same units. so it would be 8, but then the next thing you would need to look at is the exponent. Since 8^6 is not the same exponent as the two in the problem, it has to be the 8^3, which are the same  

Answer:

A

Step-by-step explanation:

Given

x² + 6x

To complete the square

add ( half the coefficient of the x- term )² to x² + 6x

x² + 6x + (3)²

= x² + 6x + 9

= (x + 3)²

Answer:

They have 425 candy bars ready to sell.

Step-by-step explanation:

Let,

x be the number of candy bars ready to sell

y be the number of chips ready to sell

According to given statement;

x+y=575     Eqn 1

x+0.5y= 500     Eqn 2

Subtracting Eqn 2 from Eqn 1

(x+y)-(x+0.5y)=575-500

x+y-x-0.5y=75

0.5y = 75

Dividing both sides by 0.5

[tex]\frac{0.5y}{0.5}=\frac{75}{0.5}\\y=150[/tex]

Putting y=150 in Eqn 1

x+150 = 575

x = 575-150

x = 425

Hence,

They have 425 candy bars ready to sell.

Answer: so basically newtons law states that unless something puts force against a moving object to stop it the object will continue moving. And unless you put force on a still object it will continue to not be in motion

Step-by-step explanation:

Answer:

[tex]d = 8 + 2t[/tex]

Step-by-step explanation:

Given

[tex]Rate = 2km/trip[/tex]

[tex]Base\ Cycle = 8km[/tex]

[tex]d = total\ distance[/tex]

[tex]t = cycles[/tex]

Required

Determine the expression for this scenario

The expression can be derived from:

[tex]Total\ Distance = Base\ Cycle + Rate * Cycles[/tex]

Substitute d for Total Distance and t for cycles

[tex]d = Base\ Cycle + Rate * t[/tex]

Substitute values for Base Cycle and Rate

[tex]d = 8 + 2* t[/tex]

[tex]d = 8 + 2t[/tex]

Answer:

64

Step-by-step explanation:

960 divided by 15 is 64. The unit rate means one so you are trying to get it to 1 second so just do 15 divided by 15 which is 1, then 960 divided by 15 which is 64

Answer:

10cm^2

Step-by-step explanation:

The parallel sides of a parallelogram is 2cm apart

Their sum is 10cm

Therefore the area can be calculated as follows

= 2 ×10/2

= 20/2

= 10 cm^2

Hence the area is 10cm^2

Answer:

Step-by-step explanation:

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

3x2+9x+4=0

For this equation: a=3, b=9, c=4

3x2+9x+4=0

Step 1: Use quadratic formula with a=3, b=9, c=4.

x=−b±√b2−4ac/2a

x=−(9)±√(9)2−4(3)(4)/2(3)

x=−9±√33/6

Answer:

0.48$

Step-by-step explanation:

Cost of 1 Apple = A

Cost of 1 Orange = O

Six apples and three oranges cost $3.36 equivalent to:

6A + 3O = 3.36 (1st equation).

Two apples and five oranges cost $3.04 equivalent to:

2A + 5O = 3.04 (2nd equation).

Now we have to solve the 2 equations with 2 uknowns (the cost of 1 Apple = A, and the cost of 1 Orange = O).

6A + 3O = 3.36 (Equation 1)

2A + 5O = 3.04 (Equation 2), multiplying this equation by 3 we get:

6A + 3O = 3.36 (Equation 1)

6A + 15O = 9.12 (Equation 2), Now equation 2 minus equation 1 we get:

6A-6A +15O -3O = 9.12-3.36 equivalent to:

12O = 5.76 => O = 5.76/12 = 0.48 ( the cost of one Orange is 0.48$)

Go back to equation 1 and solve for the cost of 1 apple:

6A + 3x0.48 = 3.36 =>

6A + 1.44 = 3.36 =>

6A = 1.92 =>

A = 1.92/6 = 0.32 ( the cost of one apple is 0.32$)

Summary: The cost of one apple is 0.32$ and the cost of one orange is 0.48$.
