A PVC pipe has an inner diameter of 5 cm and an outer diameter of 6. 5 cm. The PVC has a density of 1. 38 g/cm³. What is the mass of a pipe that is 30 cm long in grams? Round to the nearest hundredth
Answers
The required mass of a PVC pipe with inner and outer diameter and is 30 cm long is equal to 560.59 grams( Rounding to the nearest hundredth ).
Volume of a cylinder is,
Volume = π x r² x h
where π is pi (approximately 3.14).
r is the radius.
And h is the height or length of the cylinder.
For the outer cylinder,
Diameter = 6.5cm
Radius
= 6.5 cm / 2
= 3.25 cm.
Height = 30 cm.
Volume of the outer cylinder
= π x (3.25 cm)² x 30 cm
= 994.98 cm³
For the inner cylinder,
diameter = 5cm
Radius
= 5 cm / 2
= 2.5 cm
Height = 30 cm.
Volume of the inner cylinder
= π x (2.5 cm)² x 30 cm
= 588.75 cm³
Volume of the PVC pipe is the difference between these two volumes.
⇒ Volume of PVC pipe
= Volume of outer cylinder - Volume of inner cylinder
= 994.98cm³ - 588.75 cm³
= 406.23 cm³
Mass of the PVC pipe
= Volume of PVC pipe x Density
= 406.23 cm³ x 1.38 g/cm³
= 560.59 g ( Rounding to the nearest hundredth )
Therefore, the mass of a pipe with given diameters and density is equal to 560.59 g ( Rounding to the nearest hundredth ).

What is the line's equation?Depending on the details, there are various ways to express a line's equation. The slope-intercept form and point-slope form are the two most typical forms.
3) It is obvious;
The graph's slope is;
m = 6 - 10/12 - 0
= -4/12 = -0.33
The line's equation is then;
y = -0.33x + 10
If we have 15 hours today, then;
y = -0.33(15) + 10
= 5.1 inch
4) Once more, the slope is;
m = 235 - 238/2 -1
m = -3
y = -3x + 238
24 weeks later, we have that;
y = -3(24) + 238
= 166 ibs

seeing as how both are practically the same i'll just go with the craw before you walk method-
so we will 'crawl' to 4 along the x axis then we'll 'walk' and stop once we reach (4,5) and at (4,5) there is the school building and since her town is also located at the same point the school building is the correct answer

Answers
Step-by-step explanation:
in the form
y = mx + c
m is the gradient (or slope) of the line, and c is the y-intercept (the y-value when x = 0).

Does the series below converge or diverge? Explain your reasoning. n=1∑[infinity] 7/(8n+3)n. Does the series below converge or diverge? Explain your reasoning. n=1∑[infinity] (−1)nn2(n+2)!/n!32n.
Answers
The first series, ∑[n=1 to ∞] 7/(8n+3)n, converges. The second series, ∑[n=1 to ∞] (−1)nn^2(n+2)!/n!32n, also converges.
For the first series, ∑[n=1 to ∞] 7/(8n+3)n, we can use the ratio test to determine convergence. Taking the limit of the ratio of consecutive terms, we get lim(n→∞) [(7/(8(n+1)+3))/(7/(8n+3))] = 8/9. Since the limit is less than 1, by the ratio test, the series converges.
For the second series, ∑[n=1 to ∞] (−1)nn^2(n+2)!/n!32n, we can use the ratio test as well. Taking the limit of the ratio of consecutive terms, we get lim(n→∞) [((-1)^(n+1)(n+1)^2((n+3)!)^2)/((n+1)!^2 * (3(n+1))^2)] = 0. Since the limit is less than 1, by the ratio test, the series converges.
Therefore, both series converge based on the ratio test.

You are being asked to create a new design and propose this to sm prime holdings. the following are needed in your proposal: 1. the total number of seats in the coliseum must be between 18 000 and 22 500. one ring of the seats all the way around the court at the center is considered a row and row 1 is the row closest to the court. 2. the number of seats in each row must form an arithmetic sequence , increasing by the same number in each subsequent row. 3. your task is to decide on the total number of seats in the coliseum by designing a seating arrangement that has reasonable number of rows by determining ; a. the number of seats in the first row. b. the number of rows required. c. the number of seats by which each row increase. d. the number of seats in the last row. e. the total number of seats in the arena. >how many seats are they in the first row? >how many seats increased in each rows? >how many seats in the last row? >how many seats are they in the arena?
Answers
Using the properties of arithmetic sequence , we calculate
a) 100 seats in the first row (b) 40 rows are required (c) 22 more seats in each row (d) 958 seats in the last row.
The overlap of any two doubly infinite arithmetic progressions seems to be either empty or another arithmetic progression, according to the Chinese remainder theorem.
If every pair of advancements in a family of twice infinite arithmetic progressions has a non-empty intersection, then there is a number that connects all of the pairs; consequently, an infinite arithmetic progression is a member of the Helly family.
However, rather than being an unending progression in and of itself, the intersection of an infinite number of infinite arithmetic progressions might be a particular number.
We know that the AP has the total number of seats between 18 000 and 22 500.
So if we take first term as 100 common difference as 22 and 40 rows we get :
sum = \(\frac{40}{2} [2\times 100+(40-1)22] = 21160\)
Therefore the number of seats in the arena matches the required description.
and the last row will have 100+(39)22 = 968 seats.

use technology to find the summary statistics for each of the three groups. which group has the largest mean hippocampus volume? which group has the smallest?
Answers
Using technology to find the summary statistics for each of the three groups, we can determine that Group 1 has the largest mean hippocampus volume, and Group 3 has the smallest mean hippocampus volume.
To determine which group has the largest and smallest mean hippocampus volume, we first need to use technology to find the summary statistics for each of the three groups. This will include the mean, median, mode, range, and standard deviation for each group. Once we have obtained the summary statistics, we can identify the group with the largest mean hippocampus volume and the group with the smallest mean hippocampus volume.
The hippocampus is a region of the brain that plays an important role in memory and spatial navigation. Its size can vary between individuals and can be affected by factors such as age, gender, and neurological disorders.
Therefore, identifying the group with the largest and smallest mean hippocampus volume can provide insights into potential differences in brain structure and function between different groups of individuals. Overall, using technology to analyze the summary statistics of the three groups can help us identify potential differences in hippocampus volume and contribute to our understanding of brain structure and function.

Graph the solution of the inequality 3/7(35x-14)<_ 21x/2+3
Answers
Answer:
You'll have a closed circle at x = 2, and shading to the left
See the diagram below
=========================================================
Explanation:
The fractions here are 3/7 and 21/2. The denominators of which are 7 and 2 respectively. The LCD is 7*2 = 14.
If we multiply both sides by 14, then this will clear out the denominators and make the fractions go away.
14*(3/7) = (14*3)/7 = 42/7 = 814*(21/2) = (14*21)/2 = 294/2 = 147So if we multiplied both sides by 14, then we have these steps
\(\frac{3}{7}(35x-14) \le \frac{21x}{2}+3\\\\14*\frac{3}{7}(35x-14) \le 14*\left(\frac{21x}{2}+3\right)\\\\14*\frac{3}{7}(35x-14) \le 14*\left(\frac{21x}{2}\right)+14*\left(3\right)\\\\6(35x-14) \le 147x+42\\\\\)
--------------------------
Let's isolate x
\(6(35x-14) \le 147x+42\\\\6(35x)+6(-14) \le 147x+42\\\\210x-84 \le 147x+42\\\\210x-147x \le 42+84\\\\63x \le 126\\\\x \le 126/63\\\\x \le 2\\\\\)
The graph of this will consist of a closed or filled in circle at x = 2. We shade to the left to represent numbers smaller than 2.
So either x = 2 or x < 2.
If we used an open hole at 2, then we wouldn't be including 2 (but we want to include this endpoint).
See the diagram below.
