Answer:

The correct expression = 4 / 1/5

The number of rows = 20 rows

Step-by-step explanation:

1/5 Packets of C = 1 row

4 packets of C = x

Cross Multiply

1/5 × x = 4 × 1

The correct expression is

x = 4/ 1/5

x = 4 ÷ 1/5

x = 4 × 5

x = 20 rows

The number of rows Ryan can plant is 20 rows.

Answer:

1/5

In decimal = 0.2

Step-by-step explanation:

A box holds a white button, a brown button and a black button.

Hence:

Number of white button= 1

Number of brown button= 1

Number of black button= 1

Total number of buttons = 3

The probability of picking a white button then without replacing it, picking a brown button on the second pick is :

= P(White) × P(Brown) [ without replacement]

= 1/3 × 1/2

= 1/5

In decimal = 0.2

Answer:

The lengths of the sides of the rectangle are 13 inches and 15 inches

Step-by-step explanation:

The perimeter of a rectangle

Given the two sides of a rectangle a and b. The perimeter of the rectangle is:

[tex]P=2(a+b)[/tex]

We are given the perimeter of a rectangle as:

[tex]P=8(2x+1)[/tex]

And each side has a length of 3x+4 and 4x+3. Calculating the perimeter:

[tex]P=2(3x+4+4x+3)=2(7x+7)[/tex]

We set up the equation:

[tex]8(2x+1)=2(7x+7)[/tex]

Dividing by 2:

[tex]4(2x+1)=7x+7[/tex]

Operating:

[tex]8x+4=7x+7[/tex]

Subtracting 7x:

[tex]x+4=7[/tex]

Subtracting 4:

x=3

The length of each side is:

3x+4=3*3+4=13

4x+3=4*3+3=15

The lengths of the sides of the rectangle are 13 inches and 15 inches

Answer:

x = −1

Step-by-step explanation:

Answer:

x = -1

Step-by-step explanation:

7 - 7 + 16x - 12x - 6 + x = 12x - 13x - 12

Combine like terms

−6 + 5x = -x - 12

Add x to both sides

6x -6 = -12

Add -6 to both sides

6x = -6

Divide 6 to both sides

6x/6 = -6/6

x = -1

Explanation:

The lowest point occurs when y = 0.

The highest point occurs when y = 12.

The range is therefore [tex]0 \le y \le 12[/tex] which converts to [tex][0,12][/tex] which is interval notation. The square brackets tell us to include the endpoints. So we're saying that y can be anything between 0 and 12, including both endpoints.

The range is the set of all possible y outputs of a function.

Answer:

The answer is 44 field goals were attempted. The original ratio was 2/11 and in the second ratio they gave you the value of the field goals made which is 8/x.

Step-by-step explanation:

Answer:

8 out of every 44 field goals.

Step-by-step explanation:

2:11, = 4:22, = 6:33, = 8:44.

Answer:

18

Step-by-step explanation:

We know that the girl to boy ratio is 8:6 and we are told that there are 24 girls.

We multiply 8 by 3 to give us 24, so if we multiply by 3 on one side we must multiply by 3 on the other side.

This gives us a final answer of 24:18, so there are 18 boys in the class.

Answer:

Answer is choice C. We distribute the outer 2 into each of the inner terms (x and -4). Choice D is a trick answer because a lot of the time you might forget to multiply the 2 by the -4 inside the parenthesis (common mistake).

2 times x = 2x

2 times -4 = -8

2 times (x-4) = 2x-8

Side Note: Another path to solve this equation is to divide both sides by 2, then to add 4 to both sides.

Answer:

[tex]\huge\boxed{\text{0.17 hours}}[/tex]

Step-by-step explanation:

We can create two ratios to find how long you can use a bike for one dollar.

Let's set up a ratio in the form [tex]\frac{cost}{hours}[/tex]

We know it costs $23 to ride for 4 hours, so we can make the fraction [tex]\frac{23}{4}[/tex].

We also know that for $1, we'll have some unknown time for the bike. We can represent this as [tex]\frac{1}{x}[/tex].

Since the constant of proportionality has to be the same, we can set these two ratios equal to each other.

[tex]\frac{23}{4}=\frac{1}{x}[/tex]

We can now solve for x by cross multiplying.

[tex]1 \cdot 4 = 4\\\\4 \div 32 \approx 0.17[/tex]

So $1 will get you around 0.17 hours of bike time.

Hope this helped!

Answer:

0.17

Step-by-step explanation:

We can create two ratios to find how long you can use a bike for one dollar.

Let's set up a ratio in the form

We know it costs $23 to ride for 4 hours, so we can make the fraction .

We also know that for $1, we'll have some unknown time for the bike. We can represent this as .

Since the constant of proportionality has to be the same, we can set these two ratios equal to each other.

We can now solve for x by cross multiplying.

So $1 will get you around 0.17 hours of bike time.

Answer:

We know that the hotel charges 12.5% in taxes (or 0.125 in decimal form).

Then if the initial cost of the hotel, without taxes, is a, the price with taxes will be:

f(a) = a + 0.125*a = 1.125*a

And the hotel also charges a fee of $25 for each day (that is not subject to taxes) then if the total cost, with taxes, is b, the actual cost will be:

g(b) = b + 25.

Then:

a = The cost of the hotel room without sales tax or the resort fee.

f(a) and b= The cost of the hotel room and sales tax, but without the resort fee

g(b) = The cost of the hotel room, with sales tax and the resort fee.

Answer:  B.) y-1 = x-1

Step-by-step explanation:

The normal format for point-slope equations is

(y - b) = m(x - a)   a is the x-value of the given coordinate, b is the y-value and m is the slope

Here, the slope is 1, so it is understood, and 1 always "disappears" when it is a factor

So substituting the values given

(y - 4) = (x - 1)  The parentheses are unnecessary because there is no "m"

Answer:

5x^2 + 17xy - 12y^2

5x^2 + 5xy + 12xy - 12y^2

5x (x - y ) + 12 y ( x - y )

(5x + 12y ) (x-y).

Line p must be drawn so that it can lie in the same plane as line 1

Line p must be drawn in a way that allows it to lie in the same plane as line l.

In geometry, a plane extends in two dimensions indefinitely. There is no width. In coordinate geometry, a plane can be seen as an example. The positions of points in a plane are determined by their coordinates.

A plane is a flat, two-dimensional surface in mathematics that extends indefinitely. A plane is a two-dimensional analog that can incorporate three dimensions of space, a line, and a point.

Given two planes A and B,

and line l is in plane A,

to draw a line parallel to l,

"Two lines in the same plane, which are equally spaced apart and never cross" are parallel lines.

In order for a new line, p, to lie in the same plane as line l, it must be drawn parallel to line l.

Plane A contains line l.

Thus, plane A is where the line p must be drawn.

Hence option C is correct.
