Arrange the figures in increasing order of their volumes. Use Pi =22/7
Answer:
see the list below
Step-by-step explanation:
did all the formulas for each and I believe the order is from (smallest to biggest)
1. The half sphere or hemisphere (3rd in the pic)
2.The pyramid
3.slanted cone
4.cone
5.slanted cylinder
6.and finally the cylinder
Volume of cylinder II< Volume of cylinder I< Volume of Cone II< Volume of pyramid <Volume of Cone I
What is volume?The amount of space occupied by a three-dimensional figure as measured in cubic units.
Volume of Cone I = 1/3 πr²h= 1/3*22/7*5*5*7
=25 cm³
Volume of cylinder I= πr²h= 22/7*4*4*5
= 251.42 cm³
Volume of hemisphere= 2/3*πr³= 2/3*22/7*3.5*3.5*3.5
= 89.833 cm³
Volume of pyramid = l*w*h= 10*5*6
= 100 cm³
Volume of cylinder II= πr²h= 22/7*6*6*8
= 905.14 cm³
Volume of Cone II= 1/3 πr²h= 1/3*22/7*4.5*4.5*7.5
=159.107 cm³

Answer:

Step-by-step explanation:
there are two x-intercepts
For one month, 500 elementary students kept a daily record of the hours they spent watching television. The average number of hours per week spent watching television was 28. The researchers conducting the study also obtained report cards for each of the students. They found that the students who did well in school tended to spend less time watching television than those students who did poorly. Listed are several possible statements concerning the results of this research. Place a check by every statement that you agree with based on this study.
a. The sample of 500 is too small to permit drawing conclusions about elementary students in general.
b. If a student decreased the amount of time spent watching television, his or her performance in school would improve.
c. Even though students who did well in school watched less television, this doesn't necessarily mean that watching television hurts school performance.
d. One month is not a long enough period of time to estimate how many hours the students really spend watching television.
e. I don't agree with any of these statements.
Answer:
a. The sample of 500 is too small to permit drawing conclusions about elementary students in general.
C. Even though students who did well in school watched less television, this doesn't necessarily mean that watching television hurts school performance.
Step-by-step explanation:
To make inferences about a general population from sample data, we must ensure that the data is considerably large enough and randomized, this is in other to ensure that the sample is representative of the population. Hence, Making conclusion about a very large population such as here, where we want to correlate performance and playing time, a very large sample which should be atleast 10% of the population should be employed. Hence, a sample of 500 ; for making Decison about general elementary students which should run into millions require more samples.
Also Recall that, correlation does not imply causation, The fact that there is a perceives relationship between grade or performance and time spent watching TV does not necessarily mean that poor grade was caused by long duration of hours spent watching television. Other, factors such as, level of intelligence, variation of teachers competence and so on may also be causal factors.

A Labrador retriever club has 130 members: 65 black Labs, 44 golden Labs, and 21 chocolate Labs. Pablo is going to perform a chi-square goodness-of-fit test to see if the distribution of Labrador retrievers in the club is the same as the distribution nationally. Pablo is going to test his sample against the following null hypothesis, which reflects the national distribution. H0:pblack=0.53,pgolden=0.39,pchocolate=0.08 If the distribution of Labrador retrievers in the club were to match that of the national average, how many of each type of Labrador retriever would Pablo expect to see in his club? Labrador Type Black Golden Chocolate Expected Counts 68.9 50.7 10.4

9514 1404 393
Answer:
4) ΔEFG ~ ΔECD
6) Not Similar
Step-by-step explanation:
4) Shortest to longest sides are ...
EF : FG : GE = 14 : 16 : 20 = 7 : 8 : 10 (reduced)
EC : CD : DE = 7 : 8 : 10
The triangles have the same side length ratios, so are similar.
ΔEFT ~ ΔECD
__
6) Shortest to longest, the given sides have ratios ...
UT : TV = 71 : 84 (reduced)
GT : TH = 60 : 72 = 5 : 6 (reduced)
The side ratios are different, so the triangles are NOT SIMILAR.
Answer:

How many tryouts weighed MORE THAN 450 grams?
Answer:
11
Step-by-step explanation:
Basically count each doubt that is on the number line with a value greater than 450
Answer:
11 trouts
Step-by-step explanation:
Count the dots that are after the 450-gram mark.
Trouts that weigh 452 = 5
Trouts that weigh 454 = 2
Trouts that weigh 456 = 2
Trouts that weigh 458 = 1
Trouts that weigh 460 = 1
Then, add everything up.
5 + 2 + 2 + 1 + 1 = 11
So, 11 trouts weigh more than 450 grams.

(You will get brainliest if you give a long answer) You have recently purchased a new backpack as show in the picture. The main section of the backpack is made of a rectangular prism and half a cylinder. The front pocket is also a rectangular prims. Use the diagram to find the volume of your new backpack.
Explain how you calculated the answer using complete sentences and proper grammar.
*see attachment for diagram
Answer:
Volume of new backpack = 1,299.84 in.³
Step-by-step explanation:
Volume of the new back pack = volume of the front pocket + volume of the main section of the backpack
✔️Volume of the front pocket = volume of rectangular prism = L*W*H
L = 8 in.
W = 4 in.
H = 2 in.
Volume of the front pocket = 8*4*2 = 64 in.³
✔️Volume of the main section of the back pack = volume of the rectangular prism + volume of the half cylinder
= L*W*H + ½(πr²h)
L = 12 in.
W = 10 in.
H = 7 in.
r = 6 in.
h = 7 in.
Plug in the values into the equation
Volume of the main section of the backpack = 12*10*7 + ½(π*6²*7)
= 840 + ½(791.68)
= 1,235.84 in.³
✅Total volume of the new backpack = 64 + 1,235.84 = 1,299.84 in.³

Answer:
a. x=4.2, y=3
Step-by-step explanation:
We know the degrees of the two angles: Right angle (90 degrees) and 45 degrees.
The sum of the interior angles of a triangle is equal to 180 degrees, so the unknown angle is 45 degrees.
The two angles below are both 45 degrees, indicating that the side length is also 3.
So y is equal to 3, the answer can only be a.
High value points! Please find the VALUE of x and y (my last problem for my work) please help!

Answer:
Option D. 37¼ ft
Step-by-step explanation:
The perimeter of the figure above can be obtained by adding all the lengths of each sides together. This can be obtained as follow:
The lengths of each sides are given below:
Top = 6¼ ft
Left = 9⅛ ft
Bottom = 9½ ft
Right = 7¾ ft
Top horizontal = 9½ – 6¼
= 19/2 – 25/4
= 13/4 ft
Top height = 9⅛ – 7¾
= 73/8 – 31/4
= 11/8 ft
Perimeter = 6¼ + 9⅛ + 9½ + 7¾ + 13/4 + 11/8
= 25/4 + 73/8 + 19/2 + 31/4 + 13/4 + 11/8
= 149/4
= 37¼ ft
Thus, the perimeter of figure is 37¼ ft
