B. a swampland with lots of waterfowl

C. a low-lying floodplain that had rich soil

D. arid land that relied on winter rains

Answers

Answer 1

Answer:

C.) A low-lying floodplain that had rich soil.

Step by Step Explanation:

Flood-plains are the large, flat expanses of land that form either side of the river.

A flood-plain is the area around the river that is covered with river water in the times of flood.

A flood-plain area is a very fertile land due to the high alluvium sediment by floodwaters.

This process makes flood-plains a good fertile land for agriculture.

The build of alluvium on the banks of rivers can create a natural dam which can increase the river bank.

Answer 2

Answer: I think that the answer is C. a low-lying floodplain that had rich soil

Emma's tea shop has caffeinated tea and decaffeinated tea. The tea shop swerved 30 caffeinated teas and 10 decaffeinated teas. What percentage of the teas were caffeinated?

Answers

Answer:

75% of the tea is caffeinated

Step-by-step explanation:

100 = 25 25 25 25

40 = 10 10 10 10 = 75 25

therefore if 40 = 100% then subtract 25% from 40 and you get 30 or 75%

Answer:

75% HAS CAFINEEEEE

Kevan is 6 years younger than his sister Katie. Melanie is twice as old as kevan. How old are all three siblings? A. If you let K represent Katie's current age, what expression can you use to represent kevan's current age?
B. Based on your answer to part a, what expression represents Melanie's age?
C. If Melanie is 18 years old , what equation can you write to solve the problem?
D. Solve the equation. How old are kevan and Katie?

Answers

A:
k=katie's age
ke=kevan's age=k-6 (Kevan is 6 years younger than his sister Katie)

B:m=Melanie's age=2*ke=2k-12 (Melanie is twice as old as kevan)

C and D: M=18

so this means that

18=2*ke
if we divide both by 2, we get:
9=ke
Kevan is 9 years old

and 18=2k-12

add12 to both sides:
30=2k
15=k
Katie is 15 years old

Answer:

A- k-6

B- 2(k-6)

C- 18 = 2 (k-6)

D- katie- 15, kevan 9

Find the slope of (0,1) and (2,7)

Answers

slope is $\frac { y_(2) - y_(1)}{ x_(2) - x_(1)}$

if we plug in your coordinates we get:
$\frac { y_(2) - y_(1)}{ x_(2) - x_(1)} \n \frac {7-1}{2-0} \n \frac {6}{2} \n 3$

Therefore, the slope of (0,1) and (2,7) is 3.

slope= y2-y1
x2-x1
So in this case 7-1=6
2-0=2
This makes the answer 3

What is 350 divided by 10 to the power of 3?

Answers

The value of expression 350 /10³ is 0.35

What is expression?

An expression is a set of terms combined using the operations +, -, x or ÷, for example 4 x − 3 or 5 x 2 − 3 x y + 17 . An equation is a statement with an equals sign, which states that two expressions are equal in value, for example 4 b − 2 = 6 .

given statement:

350 divided by 10 to the power of 3

Now,

350 /10³

=350/1000

=0.350

=0.35

Hence, the value of expression is 0.35
