A) 4,400 yards

B) 3,520

C) 1,763 yards

D) 704 yards

Answers

Answer:

A) 4,400 Yards

Step-by-step explanation:

First, I added 1,760 + 1,760 together to represent 2 miles, and you get 3,520. Then, because it is a half mile you cut 1,760 in half to get 880. Finally, just add 3,520 + 880, which equals 4,400. I hope this helps :)

(-3,-1) -> (3,1)

Step-by-step explanation:

Reflection over the y-axis:

When we reflect a point (x,y) over the y-axis, it's y-coordinate is kept, while the x-coordinate changes signal. So

(3,-1) -> (-3,-1)

Clockwise rotation of 180º

Both coordinates of the point change signals. So

(-3,-1) -> (3,1)

Answers

Answer:

Cost of textbooks

Step-by-step explanation:

The population parameter refers to any numerical messure derived from using the entire population data. Since the study above looks to evaluate how college students view the cost of books. Since the population of interest is all students, the reason for which the entire population of students are employed and the variable that is to be measured using these population of student is called the population parameter. In the other hand, numeric estimates or observations derived from a portion of the population called the sample is refereed statistic.

What is the Pythagoras theorem?

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Given that, the completed frame is 14 inches long and 10 inches wide.

Tasha measured the diagonal length across the frame as 20 inches.

By using Pythagoras theorem, we have

20²=10²+14²

400=100+196

400≠296

Therefore, option A is the correct answer.

cuál es el porcentaje de descuento de 70 a 45​

Answers

Answer:

no habla espanol, sorry

Answer:

Utilizando la fórmula 2 y sustituyendo los valores indicados:

Precio de venta = Precio original - Valor del descuento. Así,

Precio de venta = 45 - 31.5

Precio de venta = $13.5 (respuesta)

Esto significa que el costo del artículo para usted es $13.5.

Usted pagará $13.5 por un artículo cuyo precio original fue $45 con un descuento de 70%.

En otras palabras, si usted compra una mercancía por $45 con 70% de descuento, Usted pagará $(45 - 31.5) = $13.5

Which is the sum of 8 3/4 +2 1/2?
O A. 11 1/6
B. 11 1/4
O C. 10 1/2
O D. 10 1/4

please help fast

Answers

Answer:

B. 11 1/4

Step-by-step explanation:

8 3/4 + 2 2/4 = 11 1/4

We want to sum two mixed numbers.

The correct option is D: 11 1/4

A mixed number is a number that is separated into a whole part and a rational part.

Here we want to sum:

(8 3/4) + (2 1/2)

This can be written as:

8 + 3/4 + 2 + 1/2

Now we group the whole numbers and we group the rational numbers:

8 + 3/4 + 2 + 1/2 = (8 + 2) + (3/4 + 1/2) = 10 + (3/4 + 1/2).

To perform the sum of the rational numbers, we can write:

1/2 = 2/4

Then we have:

10 + (3/4 + 1/2) = 10 + (3/4 + 2/4) = 10 + 5/4 = 10 + 4/4 + 1/4 = 11 + 1/4

Then we can see that the correct option is D.
