Mr. Reynolds is a rancher. He started with a 150 cows in his herd. Due to a hole in his fence, he now has 120 cows in his herd. By what percentage was the number of cows in Mr. Reynold's herd reduced?
Answers
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] %.

You have 8 cups of flour. It takes 1 cup of flour to make 24 cookies. The function c(f) = 24f
represents the number of cookies, c, that can be made with f cups of flour.
What domain and range are reasonable for the function?
What do the x-intercept and y-intercept of the graph above represent in this situation?
Answers
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:
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

Data Analysis — Plant ranking:
i need 7 sentences about plant ranking on plants by sand dunes please help me this is due in like 10 minutes i really need help i will give brainleist
Answers
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.

Could somebody please help me find the answers for 'x' for these pictures?
**Please let me know which one you solved along with the answer**
Answers
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
1. x=51
2. x=5
3. x=12
On a biology test, Travis got 29 questions correct but did not pass. On a second attempt, he got 38 questions correct. What was the percent of increase? Round to the nearest tenth of a percent.
Answers
We know that his first attempt he got 29 questions correct, yet he didn’t pass & the second attempt he got 38 questions correct.
So, If i’m not wrong the percentage increase is 10% [Rounded].
Explanation:
38 - 29 = 9
9 rounded to the nearest tenth is 10%.
Forgive me if I’m wrong, good luck! ^^
Answer:
Step-by-step explanation:
to find percent increase or change :
big -small ÷ original
Insert:
38-29 ÷ 29
0.31 *rounded
So, it would be a 31% increase.

What is the y-intercept of a line that has a slope of -3 and passes through point (-5, 4)? a) -17 b) -11 c) 7 d) 19
Answers
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 )

Evaluate the expression for the given values.
8x+2yz, where x=12, y = 4, and z = 2
Answers
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.
Here’s how:
8(12) + 2 x 4 x 2
96 + 16 =
112
That’s how you solve it! Hope it helps

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)
