Answer:

C. 2160π units³

Step-by-step explanation:

Volume of a cylinder is given by the formula :

V = π(12)²(15)

V = π(144)(15)

V = 2160π units³ (since it is volume)

Answer:

Answer:

  325 adult tickets

Step-by-step explanation:

This "sum and difference" problem can be solved by assigning a single variable to the quantity you want to know. Let 'a' represent the number of adult tickets sold. Then (a-60) is the number of student tickets sold, and the total number sold is ...

  a +(a -60) = 590

  2a = 590 +60

  a = 650/2 = 325

There were 325 adult tickets sold.

__

Check

325-60 = 265 student tickets were sold, for a total of 325+265 = 590.

_____

Additional comment

You may have noticed that the larger number of tickets (number of adult tickets) was found to be the average of the two numbers given in the problem statement. That will generally be the case for a "sum and difference" problem.

Pythagoras's rule:  [tex]a^2 + b^2 = c^2[/tex]  becomes  [tex]x^2 + 10^2 = y^2[/tex]

If we say b = 10: [tex]b = 10 = \sqrt{c^2 - a^2} = \sqrt{y^2 - x^2}[/tex]

You only need to look at the left triangle

Which of the options follows Pythagoras's rule?

Let's try the options until we get the right one (in no particular order)

If we try: 3) x = 4 y = [tex]29\sqrt{2}[/tex]...

[tex]\sqrt{(29\sqrt{2})^2 - 4^4} = 7\sqrt{34} \neq 10[/tex]

If we try: 4) x = 16 y = 116...

[tex]\sqrt{116^2 - 16^2} = 20\sqrt{3} \neq 10[/tex]

If we try: 2) x = 16 y = 29...

[tex]\sqrt{29^2 - 16^2} = 3\sqrt{65} \neq 10[/tex]

If we try: 1) x = 4 y = [tex]2\sqrt{29}[/tex]...

[tex]\sqrt{(2\sqrt{29})^2 - 4^2} = 10[/tex]

By using what we know about intersecting lines, we will see that:

When two lines intersect, 4 angles are formed. There are two properties that these angles have.

a) We know that ∡5 = 47°

And 7 is not adjacent to 5, then 7 has the same measure:

∡7 = 47°

b) 6 and 5 are adjacent, then we must have that:

∡5 + ∡6 = 180°

47° + (2x - 5)° = 180°

That is the equation we need to solve to get the value of x.

c) To solve the linear equation we need to isolate x, let's do that:

47° + (2x - 5)° = 180°

(2x - 5)° = 180° - 47° = 133°

2x - 5 = 133

2x = 133 + 5 = 138

x = 138/2 = 69.

Answer:

a)  <5 and <7 have congruent angles. That means that both angles are equal, they have the same measure. This means that the measure of <7 is 47°.

<7 = 47°

b) 5 and 6 are adjacent, so this is the equation that we have to do to solve for the value of x.

<5 + <6 = 180°

47° + (2x - 5)° = 180°

c) To solve the linear equation we need to isolate x.

47° + (2x - 5)° = 180°

(2x - 5)° = 180° - 47° = 133°

2x - 5 = 133

2x = 133 + 5 = 138

x = 138/2 = 69

Answer:

y=-x2 - 8x – 18 is shown by graph D.

y=x2 - 4x + 7 is shown by graph A.

y=X+5 is shown by graph C.

y=-3x - 6 is shown by graph B.

Step-by-step explanation:

In y=-x2 - 8x – 18, the coefficient of x2 is less than 0.So the graph only has a maximum value.Thefore , the graph is point upward.

In y=x2 - 4x + 7, coefficient of x2 is greater than 0.

So the graph has a minimum point and is pointed downward.

for y =x + 5, the gradient is positive.so it is graph C.There is another way to find out too but this is quicker for now.

for y = -3x - 6, the gradient is negative ,-3.So it is the graph B.

Answer: Since the pie is round it is a circle, and all circles have 360 degrees in total. Miguel cut 1/4 of the pie and 1/4 x 360 = 90. 90 is greater than 60.

Step-by-step explanation:

Answer:

Miguel has the larger piece. 1/4 is equal to 90, because 360/4 = 90.

So Miguel has the larger piece

Step-by-step explanation:

Pattern A = 1, 4, 7, 10, 13

Pattern B = 1, 5, 9, 13, 17

Each term is increases at a faster rate in pattern B; the difference between terms increases by one per step. In pattern A, 1 jumps to 4, while in pattern B, 1 jumps to 5. There is a difference of one. But when in pattern A, 4 jumps to 7, in pattern B, 5 jumps to 9. The is a difference of two between these two terms even though they are on the same "jump." This difference increases by one per "jump." (Jump is not the official word for this but I'm assuming this isn't a sequence problem.)

weekly raise= $145

let's assume the first paycheck as x.

she got a weekly raise of $145.

So, after concluding the first week she'll get $ (x+145).

likewise, after completing the second week she'll get $ (x + 145) + $ 145.

= $ (x + 145 + 145)

= $ (x + 290)

therefore, this is how her salary will get increased by $145 at the end of every week.

If Susan is 2 years older than Nancy then N=S-2 which stands for Nancy is 2 years yonger than Susan. So for the bottom eqaution, if Susan is 2 years older than Nancy then that should be S=N+2 to stand for the fact that Susan is 2 years older than Nancy.

Answer: [tex]x=18[/tex] ; [tex]y=6\sqrt{3}[/tex]

Step-by-step explanation:

You can write two expressions that are in terms of 'x' and 'y'. This is a right triangle, so Pythagorean's theorem can be used. We can also use the angle to find the sine of 30 degrees.

Pythagorean's Theorem:

The values 'a' and 'b' are the two shorter sides of the triangle, while the value 'c' is the longest side of the triangle; the hypotenuse.

[tex]a^2+b^2=c^2[/tex]

[tex]x^2+y^2=(12\sqrt{3} )^2[/tex]

[tex]x^2+y^2=12^2*\sqrt{3} ^2=432[/tex]

Sine of the Angle:

Sine is defined to be the opposite side divided by the hypotenuse. Let's take the sine of 30 degrees:

[tex]sin(\alpha )=opposite/hypotenuse[/tex]

[tex]sin(30)=y/12\sqrt{3}[/tex]

[tex]\frac{1}{2} =y/12\sqrt{3}[/tex]

[tex]y=6\sqrt{3}[/tex]

Plug this value of 'y' into the first expression derived from Pythagorean's theorem:

[tex]x^2+y^2=432[/tex]

[tex]x^2+(6\sqrt{3} )^2=432[/tex]

[tex]x^2+108=432[/tex]

[tex]x^2=432-108=324[/tex]

[tex]x=\sqrt{324}[/tex]

[tex]x=18[/tex]

Use this value of 'x' to solve for 'y' in the expression from Pythagorean's theorem:

[tex](\sqrt{324})^2+y^2=432[/tex]

[tex]324+y^2=432[/tex]

[tex]y^2=432-324=108[/tex]

[tex]y=\sqrt{108}[/tex]

[tex]y=\sqrt{36*3}[/tex]

[tex]y=6\sqrt{3}[/tex]

The point that is not on the graph of the linear equation y = 10 + x is given by:

C. (8, 2)

It is given by:

y = 10 + x.

Hence, all the points on the graph have the following coordinates:

(x, x + 10).

Option C does not follow this format, hence it is not on the graph.

Let the tens digit of the number be x .

ones digit = ( 14 - x ) ( since the sum of the 2 digits is 14 )

Two - Digit number = 10 ( tens digit ) + ones digit

Required number ,

Reversed number ,

Given ,

Reversed number - Required number = 36

✯ 140 - 9x - ( 9x + 14 ) = 36

✯ 140 - 9x - 9x - 14 = 36

✯ 126 - 18x = 36

✯ 126 - 36 = 18x

✯ 18x = 90

✯ x = 5

♧ Thus , Required number is 10 × 5 + 9 = 59

Given -

i.e, if two numbers are x and y then, x + y = 14

i.e, if 10y + x then 10y + x = 10x + y + 36.

To find -

Concept -

If a, b and c are real number (and if a and b both are not equal to 0) then ax+by=c is called a linear equation in two variables (The two variables are x and y)

The numbers a and b are called the coefficient of the equation ax+by=c. The number r is called the constant of the equation ax+by = c

PS - first we will construct two linear equations and then we'll find the number.

Solution -

Let, x + y = 14

➜ y = 14 - x ----(i)

and we'll solve 10y + x = 10x + y + 36 further,

➜ 10y + x = 10x + y + 36

➜ 10y - y = 10x - x + 36

➜ 9y = 9x + 36

➜ 9x - 9y = -36

➜ 9(x - y) = -36

➜ x - y = -4 ----(ii)

Substituting the value of y (in equation (i)) in equation (ii),

➜ x - (14 - x) = -4

➜ x - 14 + x = -4

➜ 2x = -4 + 14

➜ 2x = 10

➜ x = 10/2

➜ x = 5

Now to find the value of y we will substitute the value of x in equation (i),

➜ y = 14 - 5

➜ y = 9

Therefore, the number is {10(5)+9,i.e,} 59.
