The next three terms in the pattern following the rule 'add 9' are 36, 45, and 54.
Since the pattern follows the rule of adding 9 to get to the next term, we can simply continue this pattern from the last given term, which is twenty-seven triangles. Therefore:
Term four would have twenty-seven plus nine triangles, giving us 36 triangles.
Term five would be thirty-six plus nine, which results in 45 triangles.
Term six is forty-five plus nine, totaling 54 triangles.
The next three terms in the pattern following the rule 'add 9' are 36, 45, and 54.

In a poll of Mr. Briggs's math class, 67% of the students say that math is their favorite academic subject. The editor of the school paper is in the class, and he wants to write an article for the paper saying that math is the most popular subject at the school.
A. Explain why this is not a valid conclusion
B. Suggest a better method of determining what subject is most popular
Answer:
this would not not be a valid conclusion because only that class was included In the poll not the entire school. Another method to determine the most popular subject is to include every class(the entire school)in the poll
Answer:
1) biased sample
2) random sampling
Step-by-step explanation:
Since the results are based on feedback of students in only one class, it's not a good representative of the entire student body.
Also, since it's a math class there will be a bias.
Better method would be randomly selecting students from the entire school students list and take their feedback

If a rectangle that is 13 feet long and 4.3 feet wide is tripled in size, what is the new rectangle’s area?
Final answer:
The new rectangle formed by tripling the size of the original 13 feet by 4.3 feet rectangle has an area of 503.1 square feet, which is nine times larger than the original area.
Explanation:
To understand the scaling of the area of a rectangle when its dimensions are tripled, we need to recognize that the area of a rectangle is calculated by multiplying its length by its width.
The original rectangle has a length of 13 feet and a width of 4.3 feet, thus the area can be found by multiplying these two dimensions: 13 feet × 4.3 feet = 55.9 square feet.
When we triple both the length and width to create a new rectangle, the new dimensions will be 13 feet × 3 = 39 feet (length) and 4.3 feet × 3 = 12.9 feet (width). To find the new area, simply multiply these new dimensions: 39 feet × 12.9 feet = 503.1 square feet.
Therefore, the area of the new rectangle is 503.1 square feet, which is nine times larger than the original area because the area is proportional to the square of the scaling factor (3² = 9).

The area of a square is 81 Square
units. Find the length of a side.
Answer:
9 units
Step-by-step explanation:
To find the length of a side of a square, you need to square root the area
√81 = 9
Final answer:
The length of a side of a square with an area of 81 square units is found by taking the square root of the area, which is 9 units.
Explanation:
To find the length of a side of a square whose area is 81 square units, we use the formula for the area of a square, which is side length squared ([tex]s^2[/tex]). To solve for the side length, we take the square root of the area.
The area in this case is 81 square units, so the side length 's' will be:
√81 = 9 units
Therefore, the length of a side of the square is 9 units.

In the diagram of circle O, mNQM 103 . If the measure of LP is 30 more than the measure of MN , then determine the measure of MN . Show how you arrived at your answer.
Answer:
The measure of arc MN is 88 degrees
Step-by-step explanation:
The complete question in the attached figure
we know that
The measure of the interior angle is the semi-sum of the arches that comprise it and its opposite
so
[tex]m\angle NQM=\frac{1}{2}(arc\ MN+arc\ LP)[/tex]
we have
[tex]m\angle NQM=103^o[/tex]
substitute
[tex]103^o=\frac{1}{2}(arc\ MN+arc\ LP)[/tex]
[tex]206^o=arc\ MN+arc\ LP[/tex] ----> equation A
Remember that
The measure of arc LP is 30 degrees more than the measure of arc MN
so
[tex]arc\ LP=arc\ MN+30^o[/tex] ----> equation B
substitute equation B in equation A
[tex]206^o=arc\ MN+arc\ MN+30^o[/tex]
[tex]2arc\ MN=206^o-30^o\\2arc\ MN=176^o\\arc\ MN=88^o[/tex]
The measure of MN is 88 degrees
Circle geometryFrom the diagram shown, the formula expressed below will be used to determine the measure of MN.
<NMQ = 1/2(arcLP + arcMN)
If the measure of LP is 30 degrees more than the measure of MN, then;
arcLP = 30 + arcMN
<NMQ = 1/2(30 + arcMN + arcMN)
2(103) = 30 + 2arcMN
206 - 30 = 2arcMN
arcMN = 88 degrees
Hence the measure of MN is 88 degrees

Find the value of x such that the data set has the given mean. 102, 119, 107, 115, 110, x; mean 117
To find the value of x that results in a mean of 117 for the data set, sum the known values, multiply the mean by the total number of data points, and solve the resulting equation. In this case, the value of x is 149.
Explanation:The question asks us to find the value of x so that the mean of the data set 102, 119, 107, 115, 110, and x is 117. To calculate the mean of a data set, you sum all the values and divide by the number of values.
First, we sum the known values: 102 + 119 + 107 + 115 + 110 = 553. Since the mean is given to be 117 and we have 6 values including x, the total sum of all the values should be 117 times 6, which is 702. Now we set up the equation to solve for x: 553 + x = 702.
To find x, subtract 553 from both sides of the equation:
553 + x - 553 = 702 - 553
x = 149
Therefore, the value of x that makes the mean of the data set 117 is 149.

A cup and saucer cost $3.10 at the local store. The cup costs $2.00 more than the saucer. How much does each cost?
Answer: cup is $2.55
Saucer $0.55
Step-by-step explanation:
Cost of cup and saucer is $3.10
Let the cup be x
And saucer be y
I.e
X+y= 3.10......equation 1
Cup which is X is $2 more than the saucer
I.e x=2+y......equation 2
Substitute for X in equation 1
(2+y)+y=3.10
2+2y=3.10
2y=3.10-2
2y=1.10
Y=1.10/2
Y=$0.55
Substitute for y in equation 2
X=2+y
X=2+0.55
X=$2.55
Therefore
The cup is $2.55
The saucer is $0.55

Ifn is an odd integer that is less than -3.25,
what is the greatest possible value of n?
Final answer:
The greatest possible value of an odd integer less than -3.25 is -5.
Explanation:
Odd integers: An odd integer is not divisible by 2 and can be represented as 2n + 1 where n is an integer.
To find the greatest possible value of an odd integer less than -3.25, we need to consider the closest odd integers to -3.25, which are -5 and -3. Since the integer must be less than -3.25, -3 is not an option as it is greater. The next possible odd integer that is less than -3.25 is -5. Therefore, the greatest possible value of n that satisfies the condition is -5.

Step-by-step explanation:
The composite solid was formed by joining a square pyramid and a rectangular prism. What is the surface area of the composite solid? A rectangular prism with a length of 10 feet, width of 10 feet, and height of 6 feet. A square pyramid with triangular sides with a height of 7 feet.
Answer:
The surface area of the composite solid = 480 square feet
Step-by-step explanation: Given that the rectangular prism is of length of 10 feet, width of 10 feet, and height of 6 feet.
A square pyramid with triangular sides with a height of 7 feet.
The base of the pyramid = width of the rectangular prism.
Pyramid base = 10 feet
A pyramid has 4 triangular faces
Area of a triangle = 1/2bh
Area = 1/2 × 10 ×7 = 35 square feet
Total surface area = 35 × 4 = 140
Rectangular prism has 6 faces
But we will be calculating for 5 faces
Total surface area = 2(10×6) + 2(10×6) + (10×10)
= 120 + 120 + 100
= 340
The surface area of the composite solid = pyramid surface + rectangular prism surface
= 140 + 340
= 480 square feet

The angle of elevation of a ladder leaning against a wall is 70°. The base of the
ladder is 1.4 meters from the base of the wall. Find the length of the ladder to the
nearest tenth of a meter. *
Answer:
Refer to the explanation!
Step-by-step explanation:
We know the the angle where the ladder touches the wall at the top is a 70 degree angle, which must mean that the ladder touching the floor would be a 20 degree angle. This would be OPPOSITE / ADJACENT or TANGENT (TAN).
The TAN(20) = 2.2, when 2.2 is multiplied by the height of the ladder (1.4), you get 3.08 but rounding to the nearest tenth of a meter gives you 3.1m as the length of the ladder.
Answer: 3.1m
The length of the ladder is 4.1 meters.
The ladder and the wall forms a right-angled triangle. The ladder is represented with the hypotenuse of the triangle. The distance of the ladder from the wall is the base of the triangle.
In order to determine the length of the ladder, the acronym SOCAHTOA would be examined. We are to determine the hypotenuse given the adjacent side. So cos would be used.
Cos 70 = adjacent / hypotenuse
cos 70 = 1.4 / h
0.3420 = 1.4/h
h = 1.4 / 0.3420
h = 4.1 meters
