What is the solution to the equation 6y –2(y + 1) = 3(y – 2) + 6?
y = –10
y = –2
y = 2
y = 6

Answers

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

Answers

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.

Answers

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

Answers

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.

28 and 12 are in the middle, so add them up you get 40
Divide by 2 = 20

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?

Answers

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 sport

Question:

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 1/7

the second answer choice i belive

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

Solve for x. Round to the nearest tenth. Help

Answers

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 )

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?

Answers

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%
