How is this solved? I have been trying for hours.

dimaraw [331]

First you simplify the square root of -8, which is approximately -2.83. Subtract -2 by the square root of -8, and you'll get -4.83. Divide -4.83 by 2, and the answer should be -2.415 or -2.42. I'm not sure about this answer though.

Mrs. Santos is buying binders for the students in her class. She determined that 15 binders would cost $22.50.

atroni [7]

Answer:

It will cost $42 for 28 binders

Step-by-step explanation:

We know that 15 binders = 22.50 dollars . We need to find the cost of 18, 30, 28, and 48 binders to figure out if they match up with the statements. One way to do this is to find the cost for one binder, and then multiply that by the number of binders to find the cost for a certain number of binders. For example, if one binder costs 2 dollars, five binders would cost 2 * 5 = 10 dollars.

To figure out how much one binder costs, we can use the division property of equality to divide both sides of our equation (15 binders = 22.50 dollars) by 15. We divide by 15 because anything divided by itself is equal to 1, and that would make it 1 binder = something dollars.

Applying this, we get

(15 binders)/15 = (22.5 dollars)/15

1 binder = 1.5 dollars

For 18 binders, this would cost 1.5 * 18 = 27 dollars. We know this because we add 1.5 dollars for each binder.

For 30 binders, this would cost 30*15=45 dollars

For 28 binders, this would cost 1.5 * 28 = 42 dollars

For 48 binders, this would cost 1.5*48 = 72 dollars

The only one that matches up is 28 binders for 42 dollars

Which statement describes the pattern of the values shown in the graph?

guajiro [1.7K]

The pattern shows multiplication because the earnings are 12 times the number of hours worked in each pair of values.

We are given a graph. The graph shows the number of hours worked versus the earnings in dollars. The values of the x-coordinates are 0, 1, 2, 3, 4, and 5. The corresponding values of the y-coordinates are 0, 12, 24, 36, 48, and 60. We need to find the pattern among these values.

We can see from the data that the values are in a straight line in the graph. The coordinates have the same proportion. The constant of proportionality is calculated below.

k = 12/1 = 12

Hence, the pattern is multiplicative because the earnings are 12 times the number of hours worked for each pair of values.
