Answer:
96.29 mm^3
Step-by-step explanation:
Cylinder
V = pi r^2 h
V = 3.14 ( 2)^2 ( 5)
V = 3.14 *4*5
V =62.8 mm^3
Cone
V = 1/3 pi r^2 h
V = 1/3 (3.14) 2^2 ( 4)
V =1/3 (3.14) 4*4
V =16.746666666 mm^3
There are 2 cones so multiply by 2
Both cones = 33.493333333333 mm ^3
Add the cones and the cylinder together
62.8+33.493333333 =96.293333333
Rounding to the nearest hundredth
96.29 mm^3
What is the solution to the equation 6y –2(y + 1) = 3(y – 2) + 6?
y = –10
y = –2
y = 2
y = 6
Answer:
y = 2
Step-by-step explanation:
6y - 2(y + 1) = 3(y - 2) + 6
6y - 2y - 2 = 3y - 6 + 6
6y - 2y - 2 = 3y
4y - 2 = 3y
4y - 2 + 2 = 3y + 2
4y = 3y + 2
4y - 3y = 3y - 3y + 2
y = 2

HELP WITH THIS MATH QUESTION
Answer:
3
Step-by-step explanation:
The solution to a system of equations is the intersection point of two or more lines on a graph.
In this case, we see that at (1, 3)
Remember that this question is asking for the y intercept, not the full coordinates or the x intercept.
We know that the full coordinates are (1, 3), or (x, y), and since we need y, we know the y cooridnates are 3, not 1, since this is x.
So the first answer, A, is correct.
Hope this helps!

A pyramid has a base that is a right triangle with legs measuring 10 cm and 14 cm. The height of the pyramid is 9 cm.
The volume of the pyramid is ___ cubic cm.
Answer:
[tex]V=210\ cm^3[/tex]
Step-by-step explanation:
The legs measuring 10 cm and 14 cm.
The height of the pyramid is 9 cm.
We need to find the volume of the pyramid. The formula for the volume of a right pyramid is given by :
[tex]V=\dfrac{1}{3}Bh[/tex]
Where
B is area of base,
[tex]B=\dfrac{1}{2}\times 10\times 14=70\ cm^2[/tex]
Put all the values,
[tex]V=\dfrac{1}{3}\times 70\times 9\\\\V=210\ cm^3[/tex]
So, the volume of the right pyramid is equal to [tex]210\ cm^3[/tex].

median 10 24 9 18 15 28 12 27 25 29 10 26
Answer:
The median is 21
Step-by-step explanation:
Since you have 12 numbers in order, that's an even number, once you put them in numerical order and start crossing them off on both sides, you'll have 18 and 24 left, add them together and divide them by 2 and you'll have your median 21.
In a certain Algebra 2 class of 28 students, 9 of them play basketball and 17 of them play baseball. There are 6 students who play neither sport. What is the probability that a student chosen randomly from the class plays both basketball and baseball?
Answer:
4/28 (simplified to 1/7)
Step-by-step explanation:
Given:
There are 28 total students in the class9 of them play basketball17 of them play baseball6 of them play neither sportQuestion:
What is the probability that a student chosen randomly from the class plays both basketball and baseball?
Answer:
Because we know there are 28 total students in the class and 6 play neither basketball nor baseball, then there are 28-6 = 22 students who either play ONLY basketball, ONLY baseball, or bothWe know that 9 out of the 22 play basketball and 17 out of the 22 play baseballTherefore, 22-9 = 13 students play ONLY basketball, and 22-17 = 5 students play ONLY baseballThis means that the amount of students that play BOTH basketball and baseball is 22-(13+5) = 22-18 = 4 studentsTherefore, the probability that a student chosen randomly from the class plays both basketball and baseball is 4/28 or 1/7Help me plzzz

Answer:
1/6
Step-by-step explanation:
The multiplicative inverse of a number is that number as the denominator, and 1 as the numerator. Let's solve this problem using that knowledge.
6 × ? = 1
6 × m = 1
(m stands for multiplicative inverse)
m = 1/6

Answer:
D - x=y/12
Step-by-step explanation:
So lets just take one set of data from the table.
This is all we need.
So I am just going to set our values to:
x = 21
y = 252
Now lets plug this into each equation, ands ee if it is accurate or not:
21=12+252
=
21=264
Thats not right! Lets try the next one:
21 = 252/12
=
21 = 21
Thats correct! Lets just try the other ones anyway:
21 = 252 - 12
=
21=240
Thats not right! Lets try the last one:
21 = 12*252
=
21 = 52,424
That is most definatly not right!
So the answer is B, x=y/12
Hope this helps!

Solve for x. Round to the nearest tenth. Help
Answer:
26
Step-by-step explanation:
cosθ = adjacent / hypotenuse
cos(26) = 18 / x
x= 18 / cos(26)
x= 27.82418 ≈ 20 (to nearest tenth)
Answer:
x ≈ 20
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos26° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{18}{x}[/tex] ( multiply both sides by x )
x × cos26° = 18 ( divide both sides by cos26° )
x = [tex]\frac{18}{cos26}[/tex] ≈ 20.0 ( to the nearest tenth )
The ratio of dogs to cats at the animal shelter is 2:5. If there are 35 cats, how many dogs are there?
Answer:
Step-by-step explanation:
there are 18 dogs
Answer:
14
Step-by-step explanation:
So the ratio of dogs (2) to cats (5) is 2:5
How did we go from 5 to 35?
Multiply by 7
So multiply 2 with 7 which is 14
So there are 14 dogs

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 10 feet and a height of 8 feet. Container B has a diameter of 12 feet and a height of 7 feet. Container A is full of water and the water is pumped into Container B until Container A is empty.
To the nearest tenth, what is the percent of Container B that is full after the pumping is complete?
Answer:
79.4%
Step-by-step explanation:
the volume of a cylinder is as for any other regular 3D object
base area × height
the base area is for a cylinder a circle.
so, it is
pi×r² × height
the radius (r) is always half of the diameter.
so, volume of cylinder A is
Va = pi×(10/2)² × 8 = pi×25 × 8 = 200pi ft³
the volume of cylinder B is
Vb = pi×(12/2)² × 7 = pi×36 × 7 = 252pi ft³
therefore, in a volume of 252pi ft³ we have 200pi ft³ filled with water.
252pi = 100% filling
1% = 100%/100 = 252pi/100 = 2.52pi
how many % are 200pi ?
as many as times 1% fit into 200pi :
200pi/2.52pi = 200/2.52 = 79.36507937... ≈ 79.4%
