The sides of a whiteboard are 20 inches by 10 inches. How many 2 inch by 2 inch Post-it notes will be needed to cover the entire whiteboard?

Answer:

(-2,10)

Step-by-step explanation:

Answer:

50%

Step-by-step explanation:

Since 1,000 is 100% of the attendance, 500 is half of 1,000 meaning it's 50%.

I think the student added 50% and 100%, they could have also divided 1,500 by 10.

The actual percent increase would be equal to 50 percent.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means). Thus, that thing in number is [tex]\dfrac{a}{100} \times b[/tex]

We have been given that the Average attendance at a school’s basketball games increased from 1,000 to 1,500 last year. a student said that represented a 150% increase.

Since 1,000 is 100% of the attendance, 500 is half of 1,000 which means that it's 50%.

The student added 50% and 100%, they could have also divided;

1,500 by 10

Therefore, the actual percent increase would be equal to 50 percent.

Answer:

Step-by-step explanation:

The graph of  y=-x^2-12x-35 is attached and it has x intercepts at x=-7 and x=-5 and vertex is at (6, -107).

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

To graph the equation y=-x^2-12x-35, we can start by finding the x-intercepts (or roots) and the vertex of the parabola.

To find the x-intercepts, we can set y=0 and solve for x:

0 = -x² - 12x - 35

Using the quadratic formula, we get:

x=-b±√b²-4ac/2a

x=12±√144-140/2(-1)

x=12±√144-140/(-2)

x=12±2/(-2)

The x-intercepts are approximately x=-7 and x=-5

To find the vertex, we can use the formula x=-b/2a to get the x-coordinate, and then substitute it into the equation to get the y-coordinate:

x = -b / 2a = -(-12) / 2(-1) = 6

y = -x² - 12x - 35 = -(6)^2 - 12(6) - 35 = -107

So the vertex is at (6, -107).

Hence, the graph of  y=-x^2-12x-35 is attached and it has x intercepts at x=-7 and x=-5 and vertex is at (6, -107).

Answer:  12 different outfits

===========================================================

Explanation:

We simply multiply the values given to us. Think of a table that has 3 rows and 4 columns. The rows represent the different colors of pants Terry can wear. Each column is a different color shirt. Since we have 3 rows and 4 columns, we have 3*4 = 12 cells inside the table. Each cell represents a combination of pants and shirt colors. This means there are 12 different outfits possible.

Answer:

12

Step-by-step explanation:

if he has 3 pairs of pants and doesn't care what colors he wears then each shirt can go with the pants once and since there a 4 shirts and three pants then 3 times 4 =12

Answer:

2%

Step-by-step explanation:

This grid is a 10 by 10, meaning there are 100 total squares. If only 2 of them are shaded, our fraction would be 2/100, which is equivalent to 2%

Do you have the options for this?

SO you would have to first have the surface area of the cube which is 25 for each side so 25 x 6 = 150

Then you find the surface area for the other sides and It is 4 x 5 divided by two for each triangle on the side,  so that would be 20 and you multiply then 6.4 x 5 to equal 32 for the rectangle. The last part is the bottom and it is 4 x 5 again which is 20 so then you add them all up but im not sure.

Answer:

x=-3, and y=2

Step-by-step explanation:

Since both equations are equal to y, set them equal to each other and solve for x, that way you can solve for y:

x+5=-2x-4

3x+5=-4

3x=-9

x=-3

Plugging in x=-3 into one of the original equations:

y = x + 5

y = -3 + 5

y = 2

Therefore, x=-3 and y=2. You can also write as the ordered pair (-3,2) since that's where the two equations would intercept on a graph.

Answer:

85

Step-by-step explanation:

Scott took 7* math tests in one semester. His scores were 89 , 73 , 84 , 91 , 87 , 77 , 94.

Find the mean. To solve for the mean, add all the scores together, and divide by the amount of tests he took:

(89 + 73 + 84 + 91 + 87 + 77 + 94)/7

(595)/7 = 85

Scott's mean test score is 85.

Answer:

x = 30

ABC = 90

ACB = 30

Step-by-step explanation:

We know that if we add the 3 angles of a triangle together, it will come out to be 180 degrees, so..

60 + x + 3x = 180       subtract 60 from both sides and simplify

4x = 120          divide both sides by 4

x = 30

ABC = 3x

ABC = 3(30)

ABC = 90
