Find 26th term in the arithmetic sequence: -15,-35,-55,-75,...
Answer:
- 515
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 15 and d = - 35 - (- 15) = - 35 + 15 = - 20, thus
[tex]a_{26}[/tex] = - 15 + (25 × - 20) = - 15 - 500 = - 515
Answer:
-515
Step-by-step explanation:
In this example the first value is −15 and every value afterwards is 20 less.After substituting these values to above formula, we obtain: All we have to do is add 25 twenties or 25 x 20 = 500 and -15 - 500 = -515

What is the measure of angle b in degrees
Answer:
B=119
Step-by-step explanation:
C=180-112=68
68+51=119
A=180-119=61
180-61=119
B=119
Answer:
∠ B = 119°
Step-by-step explanation:
∠ C and 112° are adjacent angles and supplementary, thus
∠ C = 180° - 112° = 68°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ B is an exterior angle of the triangle, thus
∠ B = 51° + ∠ C = 51° + 68° = 119°
Clint found the area of the parallelogram shown. Which statement explains the error Clint made?
A parallelogram with a base of 11 centimeters, height of 4 centimeters, and side length of 5 centimeters.
Clint’s Work:
A = (b) (h). A = (11) (5). A = 55 centimeters squared.
a.Clint used the wrong units. He should have used cm, as that is what was in the diagram.
b.Clint used the wrong formula. He should have used A = one-half b h.
c.Clint did not use all three numbers in the diagram. He should have multiplied them all.
d.Clint did not use a height perpendicular to the base. He should have used 4 for the height.
Answer:
D
Step-by-step explanation:
like it said, he used 5 instead of the actual height which is 4
Answer:
D
Step-by-step explanation:
The area of a parallelogram is denoted by: [tex]A=bh[/tex] , where b is the base and h is the height that is perpendicular to the base. Depending on what kind of parallelogram it is (square, rectangle, rhombus, regular parallelogram), that height could be the side length, but usually it is not; it is only the side length in special cases, like a square.
Here, we are given that the base is 11 and that the height is 4. Since the problem gives us two different values for the height versus the side length, we know that for this parallelogram, the height is not the same as the side length. Thus, we must use 4 for the height and 11 for the base in the area formula.
Therefore, the only answer that correctly points out this mistake is D.

Answer:
Madeline: y=1x+9
Issac: y=2x+1
x=8, y=17
Step-by-step explanation:
Solving for X:
Multiply Issac's by -1:
y= 1x+ 9
-y=-2x-1
Combine:
0=-x+8
Add x to both sides:
x=8
Solving for Y:
Since we already have x, we only need to input the x value into one of the formulas:
y=1(8)+9
Simplify parenthesis with multiplication:
y=8+9
Add:
y=17
If you feel unsure, check your work with both equations:
(17)=2(8)+1
17=16+1
17=17=Good
(17)=1(8)+9

How many square feet of outdoor carpet will we need for this hole ?
Answer:
[tex]34.5^2[/tex]
Step-by-step explanation:
First figure out the rectangular part 3 x 8 = 24
Next find out the triangular part. Since we know that one half of the triangular part is 3 by 4, and a triangle is half a rectangle, we can figure out that 3 x 4 = 12 and 12/2 = 6, and do the same for the 3 x 3 triangle 3 x 3 =9 and 9/2 = 4.5
Now just add it all together: 24 + 6 + 4.5 = 34.5
A tent company makes one type of tent that is shaped like a triangular prism. The approximate dimensions are 5ft, 6ft, 9ft and 5.5ft. Based on these dimensions, how much fabric is needed to make one tent, including floor.
Given:
The base of the triangle = 6 ft
The height of the triangle = 5 ft
The other two side of the triangle = 5.5 ft and 5.5 ft
The height of the prism = 9 ft
To find the measurement of the fabric to make the tent.
We need to find the surface area of the triangular prism.
Formula
The surface area of the triangular prism is
[tex]SA = bh+(a+b+c)H[/tex]
where, b be the base of the triangle
h be the height of the triangle
a and c be other two sides of the triangle
H be the height of the prism
Now,
Putting,
b = 6, h = 5, a = 5.5, c = 5.5 and H = 9 we get,
[tex]SA = (5)(6)+(6+5.5+5.5)(9)[/tex] sq ft
or, [tex]SA = 30+153[/tex] sq ft
or, [tex]SA = 183[/tex] sq ft
Hence,
Based on the given dimension 183 sq ft fabric is needed to make the tent.

Answer:
5) 27/70
6) 90
Step-by-step explanation:
5) The first step in this problem is to figure out the amount of total spins. To do so, add up all of the numbers in the column "Frequency".
18 + 15 + 27 + 10 = 70.
Now, look at the amount of times the spinner landed on green. This is 27 times. So, the ratio of green spins to total spins is 27:70, or 27 out of 70 spins. Converting this to a fraction, we get the final answer, 27/70.
6) To solve this problem, we have to first do the same steps as the previous problem, but with the color red. There are 70 total spins, and 18 red spins. Therefore, the ratio is 18:70. However, this problem wants the total number of spins to be 350. In other words, 70 needs to become 350. To do this, multiply each side of the ratio by 5. The ratio becomes 90:350. Using this ratio, we can determine that a solid prediction is 90 red spins out of 350 total spins.
Answer:
5) 27/70
6) 90
Step-by-step explanation:
5)
What is the probability of spinning green?
Here are all of the values in the table:
Red = 18
Yellow = 15
Green = 27
Purple = 10
Add them together
= 70
Write green / total as a fraction
27/70
6)
Red = 18
Yellow = 15
Green = 27
Purple = 10
Write red / total (70) as a fraction
18/70
Multiply both the numerator and denominator by 5 to get a denominator of 350
18 * 5 / 70 * 5
90/350
Remove the denominator to find how many times he chose red out of 350 trials
90

In the square pyramid below, a = 12 ft and b = 10 ft.
What is the surface area of the square pyramid?
340 square feet
420 square feet
480 square feet
580 square feet
Square Pyramid
Hence , the surface area of the square pyramid is 340 square feet
Step-by-step explanation:
The square pyramid has a square base
Given that the base side is 10 ft and the slant height of the pyramid is 12 ft.
The surface area of a square pyramid is SA, then
SA = Area of the base + [tex]\frac{1}{2}[/tex] × P × Sh
where P is the perimeter of the base and Sh is the slant height of the pyramid
P = 4 × 10
SA = [tex]10^{2} + \frac{1}{2}[/tex]× 40 × 12
SA = 100 + 240
SA= 340 square feet
Hence , the surface area of the square pyramid is 340 square feet

what is the area of the shaded region?
Answer:
125.6 cm²
Step-by-step explanation:
Area of circle = πr²
Area of shaded region = Area of outer circle - area of the inner circle
= 3.14*7*7 - [3.14*3*3]
= 153.86 - 28.26
= 125.6 cm²
OR
= 3.14 * 7 * 7 - [3.14*3.*3]
= 3.14* [7² - 3²]
= 3.14* (7+3)(7-3)
= 3.14* 10 * 4
= 125.6 cm²
One-half of the dogs in each shelter are between which weights?

between 21 and 30 pounds in shelter A between 18 and 28 pounds in shelter B
O between 28 and 30 pounds in shelter A; between 20 and 28 pounds in shelter B
Final answer:
The correct statement is B, which describes the weight loss range for the middle 50 percent of the members, indicating an interquartile range scenario.
Explanation:
The question you've asked seems to pertain to data interpretation and understanding statistical statements regarding weight loss in a specific group of members. This seems to be a statistical analysis question which falls under the subject of Mathematics. Specifically, this question is likely related to the topics of median, quartiles, and potentially, data distribution covered in high school level mathematics.
Based on the provided statements, the correct assertion appears to be B. The middle 50 percent of the members lost from two to 8.5 lbs. This statement indicates that the middle 50 percent is referring to the interquartile range in statistical terminology, which is a measure of statistical dispersion being the difference between the 75th and 25th percentiles. Choices A and C don't provide enough information to confirm their accuracy without additional context, and choice D cannot be correct without both A and C being correct.
