Answer:

20%

Step-by-step explanation:

Therefore, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.

What is the percentage?

A percentage is a number or ratio expressed as a fraction of [tex]100[/tex]. It is often denoted using the percent sign, "%".

Here given that,

Mr. Reynolds is a rancher. He started with a [tex]150[/tex] cows in his herd. Due to a hole in his fence, he now has [tex]120[/tex] cows in his herd.

Number of cows Mr. Reynolds have

[tex]\frac{120}{150}[/tex] ×[tex]100=80[/tex] %

So, the number of cows Mr. Reynolds reduced is

[tex]100[/tex] % - [tex]80[/tex] % = [tex]20[/tex] %

Hence, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.

[tex](-0.5)(-7)(2)= (-7 )(-0.5 )(2)\\=(-7)[( -0.5)(2 )]\\=(-7)( -1)\\=7[/tex]

Step-by-step explanation:

[tex](-0.5)(-7)(2)= (-7 )(-0.5 )(2)[/tex] Here you apply the commutative law ([tex]ab = ba[/tex]).

[tex](-7)[( -0.5)(2 )][/tex] Here apply the associative law ([tex]a(bc) = (ab)c[/tex]).

Answer:

y = c(f) = 24x so range is 24  domain is 1 the  x intercept and y intercept do not count as an adding value in the equation so in order for  y = c(f) = 24x we need to make x a condition that x=1 and therefore x represents 1

Step-by-step explanation:

Given (1, 24) (8, c(f))  = 24 (8) = 192  = (1, 24) (8, 192)  Then use formula y2-y1/x2- x1 = 192-24/ 8-1 = 168/7 = 24  slope  = 24    equation = (f) = 24x The domain is all values of x that give real numbers as answers, and that is everything except 0, since 1/0 is illegal The range is all the values of y that can be reached from real values of x.

Answer:

300 + r = 217

Step-by-step explanation:

300 -> 300

added to r -> +

is the same as -> =

217 -> 217

Put this in one equation and you get:

300 + r = 217

If you need to solve for r (need to isolate r to solve for r):

300 + r = 217

r = 217 / (-300)

r = -0.723333333

Answer:

Dunes and beaches make up

nearly 1,800 of the 3,000 miles of

seacoast in the five Gulf states,

Georgia, and Puerto Rico. Erosion is

a problem on about 900 miles of

Atlantic and Gulf coast dunes and

beaches in these areas. With the

right kinds of native and naturalized

plants, much of this erosion can be

prevented.

This publication was written to

help people select and use plants to

stabilize and beautify dunes. It is

intended mainly for planners,

iandscapers, nursery operators,

developers, and homeowners. The

information applies to coastal dunes

and beaches of Puerto Rico, Texas,

Mississippi, Louisiana, Alabama,

Florida, and Georgia.

Using plants to control dune

erosion is a high priority of Soil

Conservation Service (SCS) plant

materials programs in coastal states

and the Caribbean Area. From 1973

to 1975, 191 representative dune

sites were studied in Georgia,

Florida, Alabama, and Puerto Rico

(4, 5, 6, 7, 8V These studies

identified more than 200 species of

native and naturalized dune plants

and were supplemented by less

detailed studies in Texas, Mississippi,

and Louisiana.

Of the plant species identified in

the SCS field studies, 43 have good

potential for dune revegctation

because of their favorable

characteristics for erosion control,

their frequency of occurrence, and

their dominance in the natural

ecosystem. This publication

describes each of these 43 plants,

their areas of occurrence, and

propagation techniques.

Ocean waves, littoral drift, and

other natural forces—as well as the

activities of people—determine the

adaptability and suitability of plants

for coastal dunes. This publication

explains how the dune ecosystem

and the actions of people must be

considered in planning revegetation.

It also discusses methods of

preparing the planting site and

establishing and maintaining the

plants.

SCS has selected some of the

featured plants for thorough testing

and comparison. Several years of

tests and field trials are required

before SCS and cooperating agencies

can identify superior plants and

release approved cultivars. These

cultivars are the source of

commercially produced seed and

planting stock used in local

conservation programs.

For further assistance in protecting

coastal dunes, contact your local

SCS office, which generally is listed

in municipal telephone directories

under "United States Government,

Department of Agriculture.

Answer:

112

Step-by-step explanation:

8x+2yz is our starting equation

8(12)+2(4)(2) I then substitute the variables for their numbers

96+2(4)(2) I then multiply 8x12, which equals 96.

96+8(2) I now multiply 2x4, which is 8.

96+16 I finally multiply 8x2 which is 16

112 Lastly I then add 96+16 which equals 112.

Answer:

(- 11)

Answer b is correct

Step-by-step explanation:

To find this you can use

y = mx + c

Here,

m = slope

c = y - intercept

( -5, 4) = ( x ,y)

Let us solve now .

[tex]y = mx + c[/tex]

[tex]4 = - 3 \times - 5 + c \\ 4 = 15 + c \\ 4 - 15 = c \\ - 11 = c[/tex]

Therefore,

c = (-11)

That means y - intercept is ( -11 )

Answer:

D

Step-by-step explanation:

The last number of a linear equation will always be the y intercept. In word problems, the y intercept is where the initial start is. In this case, it would be 500, the tank starts off with 500 liters. Since the "-9x" is negative(decreasing), that means that by every minute(x) 9 liters are decreasing.

Answer:

The answer is 12..

Answer:

(in order) #1

for the first one you have a vertical angle. Vertical angle is basically any 2 lines who intersect each other. The opposite sides will be congruent.

So in this case

2x+8 and 110 are oppostie sides.

2x+8=110

Which is x= 51

#2

For the second one you have supplementray angles

Now for supplementary angles its basically 2 angles added up that form a straight line And 180 degress is always the measure of a straight line. SO in this case we do

9x+12x+75=180

Which is x=5

#3

This is also a vertical angle pair and their congruent just like #1

So 5x+5=65

x=12

Answer:

what's the question?

Step-by-step explanation:

Answer:

?

Step-by-step explanation:

The open side of the inequality sign indicates the larger number. So 5 > 3, 4 < 6.

This, ≥, means it is bigger than or equal.

To show < or >, the purple arrow points to where the unknown value (x or n or k or b etc.) could be, and the dot is unfilled, or white, indicating that number is not a possible value of the unknown number.

To show ≤ or ≥, the purple arrow works the same way, it points to the where the unknown value could be. But the dot is filled, showing that the number could be the unknown value.

So for question 11, the answer is x ≤ 0 (x is less than or equal to zero).

For question 12, the answer is x > 3 (x is more than three)

Hope this helped :)
