What is the total surface area of the square pyramid below?
A. 100 cm2
B. 200 cm2
C. 280 cm2
D. 380 cm2

90⁰ counterclockwise

Answer: 2m(3m - 4n + 2)

Step-by-step explanation: Factor 4m - 8mn + 6m^2

                                                         6m^2 - 8mn + 4n

                                                         = 2m(3m - 4n + 2)

the y int of the function y = -2x + 8 is 8 or (0,8) because in y = mx + b form, the b represents the y int.

the graph...the y int is where the line crosses the y axis...and that is (0,8) or 8

Your answer would be the second option, (-4,5).

We can find this by substituting in each point into the equation y < |x - 3| and seeing if it is true.

For the first one you get 1 < |2 - 1|. |2 - 1| = |-1| = 1, and 1 cannot be less than itself, so this is false.

For the second one you get 5 < |-4 - 3|. |-4 - 3| = |-7| = 7, and 5 is indeed less than 7, so this is correct.

I hope this helps!

Step-by-step explanation:

A permutation is an arrangement of a set of objects in a specific order. The number of permutations of 10 objects taken 10 at a time is given by 10!, which is equal to 3,628,800. Thus, there are 3,628,800 different 10-letter words that can be formed from the given letters.

Answer: $60.00 (5 books), $60.00 (6 books), $32.00 (4 books) is the data set. The answer, when used in a calculator, is 3.3777777777. From this result, I would say B or $3.25 per book.

The correct answer is option B) $2.75.

The mean formula is given as the average of all the observations. It is expressed as Mean = {Sum of Observation} ÷ {Total numbers of Observations}.

By applying the formula

= 40/15

≅ 2.75

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words, it is the sum divided by the count.

Answer:

c = 4.24

Step-by-step explanation:

again, you have a^2+b^2=c^2

this time, all you have to do is substitute.

3^2+3^2=c^2

9+9=c^2

18=c^2

take the square root of both sides, you get c=(18)^1/2 or about 4.24.

To estimate how many out of 400 seventh graders prefer pepperoni based on the sample, a proportion is used, resulting in approximately 260 students preferring pepperoni pizza.

Ms. Knight wants to throw a pizza party for the seventh graders, and in a random sample, 13 out of 20 seventh graders preferred pepperoni pizza. To estimate how many out of 400 seventh graders would prefer pepperoni, we use a proportion. The proportion of students who prefer pepperoni in the sample is 13/20. To find the number who would prefer pepperoni out of 400, we set up a cross-multiplication:

Solving this equation for x (the number of 7th graders who prefer pepperoni out of 400) gives us:

So, approximately 260 seventh graders would prefer pepperoni pizza out of 400 based on the sample data.

1. Find the surface area

Side = 5 cm

Surface area = 6s²

= 6 × 5²

= 6 × 25

= 150 cm² (C)

2. Find the surface area

Side = 10 in

Surface area = 6s²

= 6 × 10²

= 6 × 100

= 600 in² (C)

Answer:

8, 2, -4, -10.

Step-by-step explanation:

Each term (except the first one) is obtained by subtracting 6 from the previous one - that is what an = a(n -1) -6 means.

First term = a1 = 8 , so the second term = 8-6 = 2.

The first 4 terms are 8, 2, -4, -10.

This is an arithmetic sequence as there is a common difference of -6.

5x+2y=147

3x+4y=133

-10x-4y=-294

-7x=-161

x=23

3(23)+4y=133

69+4y=133

64=4y

y=16

23 pies and 16 jars of apple sauce

120000+500= 120500

Answer:

Step-by-step explanation:

Answer:

The centre is (-11, -6) and the radius = 18 units.

(Option 4).

Step-by-step explanation:

If we compare this with the standard form

(x - h)^2 + (y - k)^2 = r^2

- we see that the center is (-11, -6) and the radius id √324.

The center of the circle is at (−11, −6) and the radius is 18 units.

The equation of a circle in general form is (x - h)^2 + (y - k)^2 = r^2 where (h, k) are the coordinates of the center of the circle and r is the radius. Given the equation (x + 11)^2 + (y + 6)^2 = 324, we can see that it is in a similar form but with a positive sign in the brackets. This implies that the center of the circle is at (−11, −6) and that the radius is the square root of 324, which is 18 units.

Answer:

7.7

Step-by-step explanation:

Answer: $2.20 is more. The total is $7.70. But the question is what is 40% more, so $2.20.

Step-by-step explanation:

Answer: 1

Step-by-step explanation:

(16+12x)=28

Since 4is a common factor in both terms we take out 4

4(4+3x)=28

Now take 4 to the other side

4+3x = 28/4 = 7

Similarly

3x = 7-4 =3

We end up with 3x=3

So X = 1

Final answer:

The cost of a single roll of toilet paper is $0.50, calculated by dividing the total cost of $48 by the number of rolls which is 96.

Explanation:

To find the cost of a single roll of toilet paper, we need to divide the total cost by the number of rolls. Craig bought 96 rolls of toilet paper for $48.

To calculate the cost per roll, we use the formula:

Cost per roll = Total cost / Number of rolls

So,

Cost per roll = $48 / 96 rolls

Cost per roll = $0.50 per roll

Therefore, the cost of a single roll of toilet paper is $0.50.

Answer:

BC=15.01

Step-by-step explanation:

Line segment BC can also be represented by '?'. To solve for BC, find the value of '?'

Use the tangent ratio:

[tex]tangentX=\frac{opposite}{adjacent}[/tex]

Because you need the value opposite the given angle and you are given the length of the side adjacent the given angle (hypotenuse does not count as the adjacent side, EVER (btw)). Let 65° be X and let x replace'?'.Insert the appropriate values:

[tex]tan65=\frac{x}{7}[/tex]

Solve by isolating x. Multiply 7 to both sides:

[tex]7*(tan65)=7*(\frac{x}{7})\\\\7*tan65=x\\\\x=7*tan65[/tex]

Insert this equation into a calculator:

[tex]x=15.0115...[/tex]

Round to the nearest hundredth:

[tex]x=15.01[/tex]

So, BC is 15.01

Finito.
