x: y = 1:5 Which is the correct equation? A y = 5x By= C y=x-4 D y=x+4
I'm leaning towards A but don't want totake the risk with a hour detention on the line if I get it wrong

Answers

Answer 1

The answer should be A. For example, if x = 1, and the ratio between x and y is y is 5 times greater than x, then y would equal 5, which is only true in A.

Or, use the number 5 as an example. If x = 5, and the ratio between x and y is y is 5 times greater than x, then y is 5.

And if you put that into A, y = 5x, it becomes 25 = 5(5)
Then 25 = 25, which is true!

The price of a box of colored pencils increased from $8.00 to $8.48. What was the percent increase in the price?

Answers

Step-by-step explanation:

100% = $8.00

1% = 100%/100 = 8/100 = $0.08

the price went up by $8.48 - $8.00 = $0.48.

how many % is this ?

as many % as 1% fits into this difference :

0.48 / 0.08 = 6%

the price increase was 6%.

A square with diagonals is shown. the distance from one point to the middle point is x. the length from the center point to another point is x. the length of a side is 8. the figure is a square. its diagonals meet to form four right angles. what is the approximate value of x? 2.8 units 3.3 units 4.0 units 5.7 units

Answers

The approximate value of x in the square that the diagonals meets to form four right angles is 5.7 units

Properties of a square.All the sides are equal.Opposite sides are parallel to each other.The diagonal intersects at right angle.

Using Pythagoras theorem the value of x can be found as follows:

c² = a² + b²

where

c = hypotenuse a and b are other legs

Therefore,

8² = x² + x²

64 = 2x²

x² = 64 / 2

x = √32

x = 5.65685424949

A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables.

In other words, it reflects how similar the measurements of two or more variables are across a dataset.

When one variable changes, the other variables change in the same direction or opposite direction.

Perfect positive correlation :When one variable changes, the other variables change in the same direction.

Answer:

walk area = 125.6 m²

Step-by-step explanation:

You are asked for the area of a sidewalk of given width that is around a circle of given radius. The pattern you're asked to fill in would have you compute the area of the inner circle, and of the outer circle, then find the difference between the areas.

The formula for the area of a circle is ...

A = πr²

bigger circle

The radius is shown as 11 m, so its area is ...

A = π(11 m)² = 121π m² = 379.94 m²

smaller circle

The radius is shown as 9 m, so its area is ...

A = π(9 m)² = 81π m² = 254.34 m²

area difference

The difference between the two areas is ...

walk area = big circle area - small circle area

walk area = 379.94 m² -254.34 m² = 125.6 m²

_____

Additional comment

The area can also be computed by multiplying the centerline length of the sidewalk by its width. The center of the walk is (9+11)/2 = 10 m from the centers of the circles, so the circumference (centerline length) is

C = 2πr = 2(3.14)(10 m) = 62.8 m

The width of the sidewalk is 11 -9 = 2 meters, so its area is ...

(2 m)(62.8 m) = 125.6 m² . . . . sidewalk area

Tua wanted to teach his pet raven to count because they are very smart birds. He used various fruits and nuts to represent numbers. A peanut = 1 A grape = 2 peanuts 14 is represented by an acorn and 3 grapes. An acorn is worth half a plum. What is the value in fruits and nuts, of two plums and a peanut, divided by a grape and a peanut?

Answers

The value of two plums and a peanut, divided by a grape and a peanut is 11

How to solve the expression?

The given parameters are:

Peanut = 1Grape = 2 Acorn + 3 grapes = 14Acorn = 1/2 Plum

Substitute Grape = 2 in Acorn + 3 grapes = 14

Acorn + 3 *2 = 14

Acorn + 6 = 14

Subtract 6 from both sides

Acorn = 8

Substitute Acorn = 8 in Acorn = 1/2 Plum

8 = 1/2 Plum

Multiply both sides by 2

Plum = 16

So, we have:

Peanut = 1

Grape = 2

Acorn = 8

Plum = 16

The value of two plums and a peanut, divided by a grape and a peanut is:

(2 plums + peanut)/(grape + peanut)

This gives

(2 * 16 + 1)/(2+ 1)

Evaluate

Hence, the value of two plums and a peanut, divided by a grape and a peanut is 11

The area of the circle 1 is 6π and the area of the circle 2 is 7π.

Area of the circle = π.r²

Radius of the circle 1 is less than the radius of the circle 2 this implies diameter of the circle 2 is greater than diameter of the circle 1.

if a square is drilled out from a cylinder what will be the lateral surface area,total surface area,base area and the volume of the cylinder

Answers

The cylinder is a three-dimensional shape and it has a radius, diameter and a height

How to determine the lateral surface area?

Assume the square has the following dimensions:

Base dimensions = x

Height = h

Assume the cylinder has the following dimensions:

Radius = r

Height = h

When the square is drilled out, the lateral surface area would be:

Lateral Area = Cylinder - Square

This gives

[tex]Lateral = 2\pi rh - 4xh[/tex]

Factor out 2h

[tex]Lateral = 2h( \pi h - 2x)[/tex]

How to determine the total surface area?

Using the same dimensions in (a), we have:

Total surface Area = Cylinder - Square

This gives

[tex]Area = 2\pi r(r +h) - 2(2x^2 - xh)[/tex]

Factor out 2

[tex]Area = 2[\pi r(r +h) - (2x^2 - xh)][/tex]

How to determine the base area?

Using the same dimensions in (a), we have:

Base area = Cylinder - Square

So, we have:

[tex]Base = \pi r^2 - x^2[/tex]

How to determine the volume?

Using the same dimensions in (a), we have:

Volume = Cylinder - Square

So, we have:

[tex]Volume = \pi r^2h - x^2h[/tex]

Factor out h

[tex]Volume = h(\pi r^2 - x^2)[/tex]
