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

These are the answers! I hope this helps!

A family gathered 20 small seashells from the beach bringing the total number of small seashells in their collection to 41.

options:

x-21=41

x+20=41

Answers

7 in a half because your non
20x=41 because if you have 20 sea shells + (x) x is the ones that you are missing that add up to 41 and then you would make that all equal 41

Answers

Answer:

m1 = 90°

m2 = 68°

m3 = 112°

m4 = 112°

m5 = 68°

m6 = 44°

m7 = 112°

m8 = 112°

Concept used:

- The sum of the internal angles of a triangle is 180

- With two parallel line and one oblique, the angles internal and opposite are congruent (ex: m3 and m4)

- An isosceles triangle has the base angles congruent

Step-by-step explanation:

m1 is a rectangle angle

m2 is 180-m1-22

m3 is 180-m2

m5 is 180-m4

m6 is 180-m5-m5

m3 = m4 = m7 = m8

Enter your answer as a mixed number in simplest form.

Answers

answer: p=-530 2/5

ex:

The mixed number is  [tex]-14 \frac{4}{7}[/tex]

What are Mixed Numbers?

A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.  

Given data ,

[tex]\frac{p}{1\frac{3}{7} } = -10.2[/tex]

To solve for p ,

Multiply by  [tex]1\frac{3}{7}[/tex]  on both sides we get ,

p = [tex]-10.2[/tex] × [tex]1\frac{3}{7}[/tex]

Now , [tex]1\frac{3}{7}[/tex]  can be written as the improper fraction form as  [tex]\frac{10}{7}[/tex]

So ,

p =  [tex]-10.2[/tex] × [tex]\frac{10}{7}[/tex]

p =  [tex]\frac{-102}{7}[/tex]

Now , the improper fraction [tex]\frac{-102}{7}[/tex]  can be represented by the mixed number as  [tex]-14 \frac{4}{7}[/tex]

Hence , The mixed number is  [tex]-14 \frac{4}{7}[/tex]

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.

Answers

Answer:

A. 8

Step-by-step explanation:

E for exponents (4^2)/(2^1)

4^2 = 4 * 4 = 16

2^1 = 2

D for division

16/2 = 8

So the answer is A

Hi!

Let's solve it together.

4^2 is just 4x4,

4 x 4 = 16

Next, 2^1.

2^1 is just 2, so the answer is 2.

Now, we divide 16 and 2.

16 ÷ 2 = 8

Answer:

Firstly for the the mean you add all the numbers and divide by how many they are.73+88+85+88+99+134+129 and divide it by 7 .

Secondly for the median arrange the numbers numerical form and pick the middle number.

Mode is finding the most common number.

Range subtract the largest number from the smallest number.the best measure is mean because it shows you all you bought and helps in finding the perfect amount
