Answer:

12:30 PM

Step-by-step explanation:

In 2 hours (8:30 AM and 10:30 AM) she filled half of the full pond.

So to fill the other half we double how long it has taken her to do the first half assuming she doesn't stop. Therefore, the answer will be 12:30 PM

Answer:

Hello, the pool will be full at 12:30 PM. 1200 gallons is half of the capacity of the pool (2400), and the pool was half full at 10:30 AM after being run since 8:30 AM - two hours. This means that the pool will only need two more hours to fill up, and it will be full at 12:30 in the afternoon.

Have a great day! - Mani :)

What is a scale factor?
Blababa [14]

Answer:

Here is some helpful information from my mini lessons.

Step-by-step explanation:

If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides. Here you'll learn that the ratio of the perimeters of similar figures is equal to their scale factor and that the ratio of their areas is equal to the square of their scale factor. If two polygons are similar, then the ratio of the lengths of any two corresponding sides is called the scale factor. This means that the ratio of all parts of a polygon is the same as the ratio of the sides.

Teresa is playing a video game. She earns 10 points when she completes Level 1. Each time she completes a level, she earns three
lesya [120]

Answer: 7290

Step-by-step explanation:

Three times is asking you to multiply the points before them by three. Level one, as we know is 10. Then, to get level two's points, you would multiply 10 by 3, to get 30, & so on.

Level One:10

Level Two: 10x3=30

Level Three: 30x3=90

Level Four: 90x3=270

Level Five: 270x3=810

Level Six: 810x3=2430

Level Seven: 2430x3= 7290

*** If you are still confused, comment on this question, & I will be happy to walk you through the whole question. ***

Find the value of x in the triangle shown below.
BARSIC [14]

Answer:

x=12

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

9^2 + x^2 = 15^2

81 + x^2 = 225

Subtract 81 from each side

x^2 =225-81

x^2 =144

Take the square root of each side

sqrt(x^2) = sqrt(144)

x=12
