Zach and Josh see a drawing of a quadrilateral FOUR, F(2, 2) O(5, -2) U(9, 1) and R(6, 5). Zach says the drawing is a rhombus, but not a square. Josh says the figure is a square. Who is correct? Give an explanation or work that supports your answer.

Answers

Answer 1

Answer:

Zack is correct

Step-by-step explanation:

when we plot out all the points we see that not all sides are the same length, which is techinally defines a square. Because of the different sides lengths we know it is a rhombus.

Answer 2

Josh was correct as the figure is Square.

What is Distance Formula?

In a Cartesian plane there are two points P(a, b) and Q(c, d) then the distance between two points

PQ = √(c- a)² + (d- b)²

We have the coordinates F(2, 2) O(5, -2) U(9, 1) and R(6, 5).

Now using Distance Formula

FO = √(-2 - 2)² + (5- 2)² = √16 + 9 = √25 = 5 unit

OU = √(1 + 2)² + (9-5)² = √9 + 16 = √25 =5  unit

UR = 5 unit

RF = 5 unit

and, FU = √(1 -2)² + (9- 2)² = √1 + 49 = √50 = 5√2

OR = √(5+2)² + (6-5)² = √49 +1 = 5√2

So, the given figure is square because the length of Diagonal are equal.

Tobin is solving the equation 3 (x minus 1.25) = 11.25. His work is shown below.

3 (x minus 1.25) = 11.25. 3 x minus 3.75 = 11.25. 3 x minus 3.75 + 3.75 = 11.25 + 3.75. 3 x = 15. 3 x times 3 = 45 times 3. x = 135.

What mistake did Tobin make?

Answers

he was meant to divide by 3 when the equation was 3x=15, not multiply, so he would get the answer x=5

How many rows are there?

Answers

Answer:

6 rows

Use the diagram to find the measure of angle KHL.

Answers

Answer:

m∠KHL = 43°

Step-by-step explanation:

From the picture attached,

m∠KHL ≅ m∠GHL [Given in the picture]

Now substituting the values of the angles,

(3x + 1) = (5x - 27)

1 + 27 = 5x - 3x

28 = 2x

14 = x

m∠KHL = (3x + 1)° = (3 × 14) + 1

                             = 42 + 1

                             = 43°

Therefore, measure of ∠KHL = 43°

Answers

Answer:

9.5 = y

Step-by-step explanation:

You have to use the cosine function equation.

cos(38) = [tex]\frac{y}{12}[/tex]

Multiply 12 on both sides.

12cos(38) = y

Solve.

9.46 = y

Answer:

9.5

Step-by-step explanation:

y is the adjacent side of the given 38 degree angle. You are given the hypotenuse of right angle triangle. So the trig function that you need to use is the Cosine

Cos(38) = y / 12

multiply both sides by 12

12*cos(38) = 12*y/12

12*cos(38) = y

12*0.7880= y

y =9.456

A jar can hold of a pound of flour. Austin empties of a pound of flour into the jar. What fraction of the jar is filled? Enter your answer in numerical form.

Answers

Answer:

2/3 of the jar was filled with flour

Step-by-step explanation:

The question is incomplete. Here is the complete question.

A jar can hold 3/4 of a pound of flour. Austin empties 1/2 of a pound of flour into the jar. What fraction of the jar is filled? Enter your answer in numerical form.

Given

Amount a jar can hold a = 3/4 of a pound of flour

If Austin empties 1/2 of a pound of flour into the jar, then the amount emptied into the jar b = 1/2 pounds

Fraction of jar filled will be expressed as b/a as shown;

b/a = (1/2)/(3/4)

b/a = 1/2 ÷ 3/4

b/a = 1/2 * 4/3

b/a = 4/6

Simplify to the lowest term

a/b = 2*2/2*3

a/b = 2/3

Hence 2/3 of the jar was filled with flour

Sophie and Isadora ride around a circular track that has an inner radius of 30 m. The track is 2 m wide and Isadora rides along the outer lane. How much further does Isadora ride than Sophie, In one lap? Is any one else as confused as I am?

Answers

it’s just the difference in circumferences, so it’d be
S = 2 Pi r
S = 2 * 3.14 * 30
S = 188.4m

I = 2 Pi r
I = 2 * 3.14 * (30 + 2)
I = 200.96m

I - S = 200.96 - 188.4
= 12.56m

Therefore, Isadora had to ride 12.56m more than Sophie

Antonio, Lucas y Darío compraron un refresco de 5/2 (2litros y 1/2) que piensan repartir en partes iguales. a) ¿Qué fracción de litro le corresponde a cada uno? b) Una vez repartido el refresco llego Benjamín a quien van a convidarle. ¿Cuánto debe convidarle cada uno para que los cuatro tengan la misma cantidad de refresco?

Answers

Answer:

a) A Antonio, Lucas y Darío le corresponde cada uno [tex]\frac{5}{6}[/tex] litros.

b) Antonio, Lucas y Benjamín deben convidar cada uno [tex]\frac{5}{24}[/tex] litros.

Step-by-step explanation:

a) Antonio, Lucas y Darío compraron un refresco, el cual reparten en tres partes iguales. Por tanto, la fracción de litro para cada persona es la capacidad del refresco dividido por el número de personas. Es decir:

[tex]x = \frac{\frac{5}{2}\,L }{3}[/tex]

[tex]x = \frac{5}{6}\,L[/tex]

A Antonio, Lucas y Darío le corresponde cada uno [tex]\frac{5}{6}[/tex] litros.

b) En primer lugar calculamos la fracción correspondiente a cuatro personas:

[tex]x = \frac{\frac{5}{2}\,L }{4}[/tex]

[tex]x = \frac{5}{8}\,L[/tex]

Ahora, procedemos a calcular la diferencia entre el escenario calculado en a) y el resultado anterior:

[tex]\Delta x = \frac{5}{6}\,L-\frac{5}{8}\,L[/tex]

[tex]\Delta x = \frac{40-30}{48} \,L[/tex]

[tex]\Delta x = \frac{10}{48}\,L[/tex]

[tex]\Delta x = \frac{5}{24}\,L[/tex]

Este resultado corresponde a la fracción que Antonio, Lucas y Darío deben convidar cada uno a Benjamín. Entonces, Antonio, Lucas y Benjamín deben convidar cada uno [tex]\frac{5}{24}[/tex] litros.

What is the nature of the solution set to the following system of equations?
5x - y = 2
2x -0.5y = 3

O One solution at (-4,-4)
O Infinitely many solutions
O One solution at (-4,-22)
ONo solutions​

Answers

Answer:

One solution at (-4, -22)

Step-by-step explanation:

5x - y = 2

y = 5x - 2 --(1)

2x - 0.5y = 3 --(2)

sub (1) into (2):

2x - 0.5(5x - 2) = 3

2x - 2.5x + 1 = 3

-0.5x = 2

x = -4

when x = -4, y = 5(-4) - 2 = -22

The nature of the solution set to the system of equations are,

⇒ One solution at (-4,-22).

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The system of equations are,

5x - y = 2   .. (i)

2x - 0.5y = 3  .. (ii)

Now, We can simplify as;

From (i);

5x - y = 2

y = 5x - 2

Put above value in (ii);

2x - 0.5 (5x -2) = 3

2x - 2.5x + 1 = 3

- 0.5x = 2

x = - 4

From (i);

y = 5 × - 4 - 2

y = - 20 - 2

y = - 22

Thus, The nature of the solution set to the system of equations are,

⇒ One solution at (-4,-22).

It took everly 55 minutes to run a 10-kilometer race last weekend. If you know that 1 kilometer equals 0.621 mile, how many mintues did it take everly to run 1 mile during the race?

Answers

Answer:

8.9 minutes

Step-by-step explanation:

Converting Everly Kilometer race to miles

1 km = 0.621 miles

10 km =

10 × 0.621 miles

= 6.21 miles

Hence,

6.21 miles = 55 minutes

1 mile = x minutes

Cross Multiply

6.21 × x = 55 × 1

x = 55 minutes/6.21

x = 8.8566827697 minutes

Approximately = 8.9 minutes
