You have a square flower garden that has an area of 400 square yards. What is the length of one side of the garden?
Answer:
20 yards
Step-by-step explanation:
The area of a square is calculated by multiplying its height by its base. Because they are the same in a square, the area of a square is obtained by squaring one of its sides. Let's call the sides 'x'. Then we can express the area of the garden as x^2=400.
From here we simply need to square root both sides which gives us:
x=20
Therefore the length of one side of the garden is 20 yards.

Which sequence shows the numbers in order from least to greatest? A. -2/3 , 1/5 , -3/4 B. 1/5 , -2/3 , -3/4 C. -3/4 , -2/3 , 1/5 D. -2/3 , -3/4 , 1/2 The negative signs are only for the numerators. That what it showed. Sorry I don't know how to put a picture with it.
Answer:
C. -3/4, -2/3, 1/5
Step-by-step explanation:
Just from observation, you can tell the 1/5 will be the greatest because all the other fractions are negative. Then, I converted them to decimal form to make it easier.
-2/3 = -0.6666666 (the 6 goes on forever)
-3/4 = -0.75
1/5= 0.20
Then, you put them in order.
-3/4 would be the least .
Followed by, -2/3
Finally, 1/5

Alicia has 3/4 bag of cat food. Her cat eats 1/10 of the food per week. how many weeks will the food last
Answer:
It would last 7 1/2 weeks if i'm correct
Answer:
the food will last for 7 weeks
Step-by-step explanation:
so 3/4 bag of food is 75 % of cat food and thats out of 100 so 1 out of 10 is basically 10 out of 100 and since there is only 75 ,10 goes into that 7 times so its 7

What is the modulus function?The modulus function is the function which gives the magnitude or absolute of the number in the variable.
|x|=x if x>0
-x if x<0
0 if x=0
So according to question,
|7x+21|=14x
case-1: if 7x+21>0
⇒7x>-21
⇒x>-21/7
⇒x>-3
if 7x+21>0 , Using the modulus function property
|7x+21|=14x
⇒7x+21=14x
⇒14x-7x=21
⇒7x=21
⇒x=21/7
⇒x=3 which is also x>-3
x=3 is the solution
case-2: if 7x+21<0
⇒7x<-21
⇒x<-21/7
⇒x<-3
if 7x+21<0 , Using the modulus function property
|7x+21|=14x
⇒-(7x+21)=14x
⇒-7x-21=14x
⇒14x+7x=-21
⇒21x=-21
⇒x=-21/21
⇒x=-1 for which x<-3 is not true
x=-1 is an extraneous solution.
Therefore the solution is 3 and the extraneous solution is -1.

The length of C. D. Akers rectangular garden is 37 feet shorter than six times the width. If the perimeter of
his garden is 164 feet, what are the dimensions of Mr. Akers' garden?
Answer:
17 feet by 65 feet
Step-by-step explanation:
If w represents the width of the garden, then 6w-37 is the length. The perimeter of a rectangle is twice the sum of length and width, so the perimeter is ...
164 = 2(w +(6w -37)) = 14w -74
238 = 14w
238/14 = w = 17
__
6w-37 = 6·17 -37 = 65
The width of the garden is 17 feet; the length is 65 feet.

(2,1), (-4,5), (1,7), (2,-3), (-1,2) Find domain and range.
1.Phone company A charges $20 a month and $0.10 per minute of phone calls. Phone Company B charges
$15 a month and $0.20 per minute of phone calls. How many minutes of phone call will it take for
Company A to cost the same as Company B?
I might be wrong but I think it's 50 minutes.
$0.10 x 50min = $5
$20 + $5 = $25
$0.20 x 50min = $10
$15 + $10 = $25
So, it's 50 minutes.

3(5m – 7) + 4 = 8m + 18
Can you also explain it. I stuck on where the +4 goes
Answer:
m=5
Step-by-step explanation:
Firstly we know we are solving for M.
So we start like this.
[tex]3(5m - 7) + 4 = 8m + 1 [/tex]
use the distributive property to multiply 3 by 5m-7=
[tex]15m - 21 + 4 =8m + 18[/tex]
Add -21 and 3 to get -17
[tex]15m - 17 = 8m + 16[/tex]
subtract 8m from both sides
[tex]15 m - 17 - 8m = 18[/tex]
combine 15m and -8m to get 8m
[tex]7m - 17 = 18[/tex]
Add 17 to both sides
[tex]7m = 18 + 17[/tex]
Add 18 and 17 to get 35
[tex]7m = 35[/tex]
Divide both sides by 7
[tex]m = \binom{35}{7} [/tex]
Divide 35 by 7 to get 5
[tex]m = 5[/tex]

There is a 12.5% tax on items purchased in Arlington. What is the percent of the original price you will pay? Write your answer as a percent, decimal and fraction in the space below.
I have to pay 12.5% more than the original price.
The decimal representation is 0.125.
The fractional representation is 112.5/100.
What is the percentage?The percentage is the value per hundredth.
Given there is a 12.5% of tax on items purchased in Arlington.
Assuming the original price of a product is 100 dollars.
∴ The price of the product with 12.5% of tax is,
= (100 + 12.5)/(100)×100.
= 112.5 dollars.
∴ I have to pay 112.5 dollars for every 100dollar product.
So, the percentage of the original price that I have to pay is (112.5/100).
= 12.5%.
The decimal value of 12.5% is (12.5/100) = 0.125.
The fractional representation is 112.5/100.

Read the passage. Cooperative Trees We often think of trees as simple objects that provide us with things we need, such as lumber, shade, or fruit. Yet trees are far more complex—and social—than we recognize. An underground network of fungi, which some have called the "wood-wide web," connects the roots of numerous trees in a forest. Using the network, trees can communicate with and support one another. They may share water, carbon, nutrients, and protective compounds with one another. Scientists believe that one explanation for this phenomenon may be a "source-sink model." According to this theory, trees growing in excellent conditions with many resources transfer these resources to trees growing in less favorable conditions. In this way, trees in a forest ensure the health of the entire community by working cooperatively. What is the main idea of the passage?
Answer:
Trees have an underground network of fungi that help them support each other.

Answer:
x=12
Step-by-step explanation:
14/21=16/(x+12)
cross multiply
14(x+12)=16(21)
14x+168=336
14x=336-168
14x=168
x=12 (so the side would be x+12=24)
You could also see that 14 is 2/3 of 21, so 16 has to be 2/3 of x+12. That means x+12 would have to equal 24. If you take the 12 away from 24, x=12.
