If in lixue's garden the green pepper plants grew 5 inches in 3/4 months then at this rate they can grow 0.555 feet in one month

The problem is solved as per the unitary method

In lixue's garden the green pepper plants grew 5 inches in 3/4 months.

In 3/4 months the green pepper grew by 5 inches.

3/4 months can be written as 0.75 months

in 1 month the green pepper plant will grow by (5/0.75) 1

The green pepper plant will grow by 6.66 inches

1 foot is equals to 12 inches

1 inch = 1/12 foot

6.666 inches = (1/12) 6.666

= 0.0833 x 6.666

= 0.555

the plant grew 0.555 feet in 1 month

Therefore, if in lixue's garden the green pepper plants grew 5 inches in 3/4 months then at this rate,they can grow 0.555 feet in one month

The value of the smaller number is 5

From the question, we are to determine the value of the smaller number

Let one of the numbers be x and the other number be y

From the given information,

The difference of two numbers is 1

That is,

x - y = 1

and

Their sum is 11

That is,  

x + y = 11

Now, we will solve the equations simultaneously

From the first equation

x - y = 1

x = 1 + y     ------------- (3)

Substitute into the second equation

x + y = 11

1 + y + y = 11

1 + 2y = 11

2y = 11 - 1

2y = 10

y = 10/2

y = 5

Substitute the value of y into equation (3)

x = 1 + y

x = 1 + 5

x = 6

Hence, the number is 5

It is to be noted that the amount of cubic yards of topsoil that Helena purchased is 7 Cubic Yards. (Option D) Here is how we arrived at that answer.

Let the compost purchased be x cubic yards

And the topsoil purchased be y cubic yard

Hence

x+y = 10 .......................................1

Also

Total cost incurred = 25x+15y=180

Dividing the whole equation by 5 we get

5x+3y=36 ........................................2

Multiply 1 by 3 and subtract it from 2

5x+3y=36

-

3x+3y=30

2x      =6 Solving for x

x = 3

Plug x back into equation 1, and we have

x+y=10, this become

3+y=10 Solving for y, we have

y=10-3

=7

Hence it is correct to state that Helena purchased 7 cubic yards of topsoil.

The equation of the line perpendicular to y = 6x -2 and passes through (6, -2) is y = - 1 / 6 x - 1

The equation of a linear graph can be represented in slope intercept form.

Therefore,

y = mx + b

where

Therefore,  the equation of the line is perpendicular to y = 6x -2 and passes through (6, -2).

Perpendicular lines follows the rule below:

m₁ m₂ = -1

6m₂ = -1

m₂ = - 1 / 6

Therefore, let's find the y-intercept using (6, -2)

y = - 1 / 6 x + b

-2  = - 1 / 6 (6) + b

- 2 + 1 = b

b = -1

Answer:

32 square units

Step-by-step explanation:

A plot of the points shows that PQRS is a rectangle.

The length of this is the distance of the segment PQ = distance of segment RS = 6.4 units

The width QR = width PS = 5 units

The area is 5 x 6.4 = 32 square units

Lengths are calculated as follows

Finding length of PQ using distance formula:
[tex]\overline{PQ} = \sqrt{(4-0)^2 + ((7-2)^2}\\\\= \sqrt{4^2 + 5^2}\\\\= \sqrt{16 + 25}\\\\= \sqrt{41}\\\\= 6.4\\[/tex]

Finding length of QR using distance formula:
[tex]\overline{QR} = \sqrt{8-4)^2 + (4 - 7)^2}\\\\= \sqrt{4^2 + (-3)^2}\\\\= \sqrt{16 + 9}\\\\=\sqrt{25}\\\\= 5\\[/tex]

What is Compound Interest?

Compound interest is calculated by multiplying the initial loan amount, or principal, by the one plus the annual interest rate raised to the number of compound periods minus one.The formula is,

A = P(1 + r/n)^(n*t)

Given,

principle P = $900

rate r = 6%

time t = 10 years

Put these values in formula, i.e, A = P(1 + r/n)^(n*t)

Given:

A U.S. Geological Survey map has a scale of 1:24200

There are two buildings that are 3.38 miles apart.

We will find how they are inches apart on the map

First, convert from miles to inches

1 mile = 63 360 inches

So, 3.38 miles = 3.38 * 63 360 inches = 214156.8 inches

The map has a scale of 1:24200

So, using the ratio and the proportions, we will find the length on the map as follows:

Rounding to the nearest hundredth

So, the answer will be: 8.85 inches

The original price of the toy is p.

An easier way to understand this problem is : The original price is 1, or 100%. Now, it's reduced by 15%, so the new price is 100% - 15% = 85%.

85% can be converted to 0.85, or 85/100. Therefore, the answer is 0.85p

Using limit definition of the derivative, The value of f'(3) is 2.

By determining the limit of a slope expression, one can get the instantaneous rate of change (derivative).

The derivative of a function f at x is the instantaneous rate of change of the function at x since the derivative is defined as the limit that determines the slope of the tangent line to a function.

Given function

f(x) = x² - 4x.

derivate with respect to x

f'(x) = 2x - 4

put x = 6

f'(x) = 2(3) - 4

Two angles are complementary. The measure of the larger angle is 10 greater than 9 times the smaller angle, so the measure of both angles will be 8° and 82°.

The two angles' complement and supplement are determined by the sum of their measurements. The two angles are said to be complimentary if their combined measurement equals that of a straight angle.

According to the question, the equation will form :

x = 9x + 10                      (1)

As we know that for complementary angles,

x + y = 90°

9y +10 + y = 90°

10y = 80°

y = 8°

Substitute this value in equation (1)

x = 9(8) + 10

x = 82°.

Answer:

y = x - 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 1 , then

y = x + c ← is the partial equation

to find c substitute (2, - 1 ) into the partial equation

- 1 = 2 + c ⇒ c = - 1 - 2 = - 3

y = x - 3 ← equation of line

The values of the variables are :

10. x = 8 and y = 9

11.  x = 20 /9 and y = - 7/ 9  

12.  x = 3.08 and y = 4x = 12.32

10 . Given equations are ; 7x -5y = 11 ------- equation 1

and y = x + 1

On substituting this value in equation 1

we get 7x - 5 ( x + 1) = 11

7x - 5x - 5 = 11

2x = 16

x = 8 and thus y = 8 + 1 = 9

11. Given equations are : 5x - 4y = 22

x = y+ 3

On again substituting the values we get

5y + 15 - 14 y = 22

- 9 y = 7

y = - 7/ 9 and x = 20 / 9

12. Given equations are 3x + 8y = 108

and y = 4x

On again substituting equations we will get

3x + 32x = 108

35 x = 108

x = 108 / 35

x = 3.08 and y = 4x = 12.32

Given that g(x)=2x + 1,

therefore, the value of g(a+h) and g(a) can be written as,g(x)=2x + 1g(a+h)=2(a+h) + 1     
   = 2a + 2h + 1

g(x) = 2x + 1g(a) = 2(a) + 1   
   = 2a + 1

Now, the value of g(a+h)-g(a) will be,

g(a+h) - g(a)= (2a + 2h + 1) - (2a + 1)= 2a + 2h + 1 - 2a - 1= 2h

Hence, the value of g(a+h)-g(a) is 2h.

The length of the arc whose central angle is 50° is 10.91.

Here, we are given that a circle has a circumference of 25π.

The length of the arc of a circle is given by the following formula-

(∅/360)*2πr

where ∅ is the measure of the angle that the arc subtends at the center and r is the radius of the circle.

Here, we are already given the circumference, thus, 2πr = 25π.

And, the central angle is given to be 50. Thus, ∅ = 50

Now, substituting the values in the above formula we can calculate the length of the arc as follows-

(50/360)*25π

= 5/36 × 25π

= 125/36 × 22/7

= 2,750/ 252

= 10.91

Tables can help to see patterns in data. Tables make the most difficult problems much easier. These are the advantage to using tables.

The reader can immediately examine the results by using tables to organize data that is too complex or detailed to be fully described in the text. By omitting numerical data from the text, they can be used to highlight trends or patterns in the data and to improve the readability of manuscripts. A table is a way to organize information or data, usually in rows and columns but sometimes with more complicated structures. In research, communication, and data analysis, tables are frequently employed. Large amounts of numerical or statistical data can be efficiently and effectively represented using scientific tables and graphs. In contrast to reading a verbose description of the information, readers are frequently drawn to tables and figures because they view them as being easier to understand.
