31. What is the surface area of the pyramid to the nearest whole number?

A 25 cm
B 60 cm
C 30 cm2
D 85 cm2

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%

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:

oh wait i got it! those are oppisite from eachother so theyre angle is the same. the answer would be 59°

Answer:

b=59º

Step-by-step explanation:

Vertical angle theorem states that if angles are vertical, they are congruent.

Answer:

2 units

Step-by-step explanation:

Congruent triangles are those triangles, which have same shape & size (same side & angle size).

If  ΔEFG ≅ ΔXYZ. And, E (0, 0), F (0, 2), and G (3, 0)

So, length EF = length XY.

Length of E (0,0) & F (0,2) is 2 units

As triangles are congruent, EF = XY

Hence, measure of XY = 2 units

Answer:

26 is 7.05% or 7.04% of 369.

Step-by-step explanation:

Now 7.04% of 369 is actually 25.9776.

and 7.04% is 26.01452.

But if you round both 25.9776 and 26.01452 you get 26

So, technically you are correct.

Hope this helps! :)

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.

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: 235.5 cm³

Step-by-step explanation: Volume of a cylinder is the area of the circular base times the height of the cylinder:

2. x = 50 equation is x + x + 12 = 112, then solve for x

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:

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

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
