Rosie ran directly toward her home at a constant velocity for 78 seconds. In one-third of that time, she ran 52 meters. What was Rosie's velocity?

Answers

Answer 1

The velocity of Rosie when running is 2 meters per second

How to determine the velocity of Rosie?

From the question, we have the following parameters that can be used in our computation:

Time = 1/3 of 78 seconds

Distance covered = 52 meters

The velocity can be calculated using the following equation

Velocity = Distance covered/Time

Substitute the known values in the above equation, so, we have the following representation

Velocity = 52/(1/3 * 78)

Evaluate the quotient

Velocity = 2

Hence, the velocity is 2 meters per second

George bought a model of a Viking ship for $68. If he paid
$5.10 in sales tax, what was the sales tax rate?

Answers

Answer:

We can convert 6.75% to a decimal by dividing by 100.

If x is the price of the house, then the sales tax is 0.0675x. The price of the house and the sales tax add up to $319,000.

x+0.0675x=319,000

Combe terms on the left.

1.0675x=319,000

Finally, divide both sides by 1.0675.

x=319,0001.0675=298,829.04

What are similar figures?

Two figures are defined as similar triangles when they share these two features listed as follows:

Congruent angle measures, as both triangles have the same angle measures.Proportional side lengths, which helps us find the missing side lengths.

Hence the top left figure is similar with the figure given in this problem, as:

5/2 = 20/8.The angle measures are the same.

Observa los puntajes de las respuestas de una evaluación que tuvo de 100 preguntas. Si Alfredo contestó correctamente 57 preguntas, 16 incorrectas y el resto las dejó en blanco, ¿qué puntuación obtuvo en la evaluación?

Answers

La pregunta está incompleta:

Puntos por respuesta:

Correctas: 4

En blanco: -1

Incorrectas: -3

Answer:

Alfredo obtuvo una puntuación de 153.

Step-by-step explanation:

De acuerdo a la información proporcionada, conoces el número de preguntas en la evaluación y el número de preguntas que Alfredo contestó de forma correcta e incorrecta y tienes que restar estas del total de preguntas para encontrar el número de preguntas que dejó en blanco:

100-57-16=27

Ahora, debes multiplicar el número de respuestas correctas, incorrectas y en blanco por su respectivo puntaje:

Correctas: 57*4=228

En blanco: 27*(-1)=-27

Incorrectas: 16*(-3)=-48

Finalmente, debes sumar los resultados obtenidos por cada tipo de respuesta:

228+(-27)+(-48)= 228-27-48=153

De acuerdo a esto, la respuesta es que Alfredo obtuvo una puntuación de 153.

Matt decides the length of his table will be 15 in. He calculates that the area of the table is 30 in. squared. Determine if Matt’s calculation is correct

Answers

Answer:No Matt's calculation is not correct.

Step-by-step explanation:

We have to multiply by the number of the area.If it is 4 inches we multiply by 4

15 x 4 =60

A=4 inches squared

A=LxW (length x width )

so you can say that:

Matt is incorrect because He skipped the step of multiplying 2 by 2 in the formula which is where we get 4 from.

To find area, you do length * width
For the rectangle, the length is 48 inches and the width is 32 inches.
To find the area of the rectangle, we do 48 * 32
48 * 32 = 1,536
The area of the rectangle is 1,536 inches.
To find the area of a triangle, it is a little different.
To find the area of a triangle, you use the following formula: A = 1/2 bh
We use 48 inches for the base of the triangle since the base side is equivalent to the base side of the rectangle, which is 48. We use 12 inches for the height.
In this case, we do: Area = 1/2(48)(12)
Using PEMDAS, we do multiplication or division depending on which one comes first.
In this case, division comes first
1/2(48) or 48/2 = 24
Then multiply
24 * 12 = 288
The area of the triangle is 288 inches.

luisa is building a sand box in her backyard. she places four pieces of wood in a rectangle to form the frame. the rectangle is 4 feet long and 3 feet wide. how can she use a measuring tape to make sure that the corners of the frame will be right angles?

Answers

Answer:

As we know rectangles have 90 degree angles at all 4 of its corners.

In this question we know that the length is 4 feet while the bredth is 3 feet.

Therefore to solve this answer we can use the Pythagoras theorm.

By Pythagoras:

[tex]4^{2} + 3^{2} = diagonal^{2}[/tex]

Therefore the diagonal must be 5 feet

So if Luisa measures the diagonal with a tape and it measures 5

Then it proves that all 4 corners due have 90 degree angles
