Answer:

Step-by-step explanation:

Writing equations from words is mostly a matter of understanding what the English words mean.

If the first number is x, then the square of the first number is x². That is said to be equal to the sum of the second number (y) and 16:

  x² = y + 16 . . . . the first equation

The wording "the difference of A and B" is usually intended to be interpreted to mean A-B. Here, we have the difference of 4 times the second number (4y) and 1, so ...

  4y -1

This is equal to the first number (x) multiplied by 7, so ...

  4y -1 = 7x . . . . the second equation

__

These can be solved a variety of ways. When no method is specified, I like to use a graphing calculator. It shows the only integer solution for this pair of equations is ...

  (x, y) = (5, 9)

Answer:

5/14

Step-by-Step Explanation:

When dividing fractions, we have to change the division sign to a multiplication sign in order to make the problem easier. When we change signs, we also have to flip the second fraction in the equation. So, the fractions would turn into:

2/7 x 5/4

2 x 5 is 10, and 7 x 4 is 28. 10/28 simplified is 5/14.

Answer:

Derek would have to buy 3 packs of 8 hotdogs and 2  packs of 12 hotdog buns.

Step-by-step explanation:

This is because 8 times 3 is 24 and 12 times 2 is 24.

8 and 12 both have a common multiple, which is 24.

So if he buys 3 packs of hotdogs, which come in packs of 8, he'll get 24.

And if he buys 2 packs of buns, which come in packs of 12, he'll get 24.

Answer:

160

Step-by-step explanation:

90% of 160 is 144

Answer:

13.52

Step-by-step explanation:

If the distance between A and FL is the same between A and RN, you know that the angle between then is the same (90°). The two lines have the same lenght.

So, if RN is 13.52, FL is 13.52 too.

The length of the chord FL will be 13.52 units. Then the correct option is D.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

If the distance of the two chords from the center of the circle is the same, then the two chords are equal to each other.

The length of the chord RN is 13.52 units. The distance between the chords RN and FL from the center of the circle is 7.73 units.

If the distance between the chords RN and FL from the center of the circle is the same, then the length of the chords RN and FL will be equal to each other.

The length of the harmony FL will be 13.52 units. Then the right choice is D.

Answer:

y = 0.8x + 0.5

Step-by-step explanation:

Let the equation of the line passing through a point (x', y') is,

y - y' = m(x - x')

Here, m = slope of the line

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the table attached,

Line represented by the table passes through two points (1, 1.3) and (1.5, 1.7).

Therefore, slope of the line (m) = [tex]\frac{1.7-1.3}{1.5-1}[/tex]

m = [tex]\frac{0.4}{0.5}[/tex]

m = 0.8

Equation of the line passing through (1, 1.3) will be,

y - 1.3 = 0.8(x - 1)

y = 0.8x - 0.8 + 1.3

y = 0.8x + 0.5

You have to multiply the number of hours Diana works by the amount of money she earns, which is $8.50, in order to know how much she earns in total.

Answer:

R = √(2/3)

h = 1/√3

Step-by-step explanation:

Given that

The volume of a cylinder, V = πr²h

Assuming that the hypotenuse of a right angles triangle in the cylinder is 1. This means the square of the adjacent and the opposite sides is equal to one. And thus,

r² + h² = 1

r² = 1 - h²

If you substitute for r² in the volume of the cylinder, you have

V = π(1 - h²)h

V = πh - πh³

To find the critical point, we differentiate V, so that

dV = π - 3πh², if we equate this to zero, we have

π - 3πh² = 0

π = 3πh²

1 = 3h²

h² = 1/3

h = 1/√3

Also, to find for which value of h do we have maximum or minimum volume, we differentiate again. So that.

V'' = 0 - 6πh

On substituting for h, we have

V'' = -6π * 1/√3

This invariably means that V'' of 1/√3 is less than 0(since it's negative)

Going back to the first formula of r, we have

r² = 1 - h²

On substituting for h, we have

r² = 1 - (1/√3)²

r² = 1 - 1/3

r² = 2/3

r = √(⅔)

The radius and height of the cylinder of maximum volume are;

Radius = √6

Height = √3

Formula for volume of a cylinder is;

V = πr²h

       We are told that the hemisphere has a radius of 3 and sits on a horizontal plane. This means that the radius of the sphere will be the diagonal gotten from the intersection of the radius (r) of the cylinder and the height (h) of the cylinder. Thus, from Pythagorean theorem, we have;

r² + h² = 3²

r² = 9 - h²

Volume is now;

V = π(9 - h²)h

V = π(9h - h³)

Let us find the derivative of the volume and equate to zero the find the height and radius at maximum volume. Thus;

dV/dh = π(9 - 3h²)

At dV/dh = 0;

π(9 - 3h²) = 0

Thus; 3h² = 9

h² = 9/3

h² = 3

h = √3

Thus; r² = 9 - (√3)²

r² = 9 - 3

r² = 6

r = √6

Answer:

50% I believe?

Step-by-step explanation:

Answer:

because the price of 2 adult tickets and 4 child tickets is $48

=> 2x + 4y = 48 (*)

the price of 5 adult tickets and 2 child tickets is $64

=> 5x + 2y = 64 (**)

from (*) to (**), we have:

[tex]\left \{ {{2x+4y=48} \atop {5x+2y=64}} \right.\\\\<=>\left \{ {{10x+20y=240} \atop {10x+4y=128}} \right.\\\\=>\left \{ {{20y-4y=240-128} \atop {2x+4y=48}} \right.\\\\<=>\left \{ {16y=112} \atop {2x+4y=48}} \right.\\\\<=>\left \{ {{y=7} \atop {x=10}} \right.[/tex]

so the ticket price for one adult is $10

the tickey price for one child is $7
