Answer:
√9 = ±3
Step-by-step explanation:
... Because 3 × 3 = 9 and (-3) × (-3) = 9
However, it is agreed universally that we take the so-called “positive square root”. That is, we accept that the only answer is 3. In contrast, when we have (x^2) =9, where x is a variable, we don't know whether x is positive or negative so we cannot rule out the possibility that x is negative.
Square root means a number that produces a specified quantity when multiplied by itself.
Answer:
± 3
Step-by-step explanation:
[tex]\sqrt{9}[/tex] = ± 3
That is + 3 or - 3
Since 3 × 3 = 9 and - 3 × - 3 = 9

Mrs. Lee's gross biweekly salary is $1230. What is her gross monthly salary?
Answer:
$4920
Step-by-step explanation:
one month=4 weeks
1230×4
4920
Answer:
$2460
Step-by-step explanation:
A biweekly salary is basically just saying every 2 weeks so because a month is about 4 weeks you would just double the biweekly salary so:
$1230 × 2 = $2460

See pic below.
Step-by-step explanation:
Create a table of values by letting x equal some numbers such as 0, 1, 5, 7. You can use others, too.
You started filling out the table correctly.
Find the corresponding y-coordinates and write them in the table.
Then plot each point on the graph using a dot.
Then connect the dots with a line.

A rectangular garden is 14 feet wide and 48 feet long.
If you stand in one corner of the garden, how many feet
away is the corner diagonally across from you?
Answer: 50 feet
Step-by-step explanation:
Since it is a rectangle and you in the corner diagonally; you can draw a line diagonally across in the rectangle and you are left with two triangles.
So since its two right-angled triangles
a = 14 feet
b = 48 feet
You need to find c which is the diagonal.
Using the pythagorean theorem which is:
[tex]c^{2} = a^{2} + b^{2}[/tex]
[tex]c^{2} = 14^{2} + 48^{2}[/tex]
Square the a and b then add
[tex]c^{2} = 136 + 2304[/tex]
[tex]c^{2} = 2500[/tex]
Now carry over the square on the c and change it to the square root
[tex]c = \sqrt{2500}[/tex]
when you square root
[tex]c = 50[/tex]
therefore it is 50 feet diagonally across

A car's odometer starts at 25 miles and for every 25 miles traveled, 1 gallon of gas is used.
Based on this information, which graph best shows this relationship between the miles traveled, y, and the gallons of gasoline used, x?
The obtained coordinate points to plot the graph are matching with graph C. Therefore, option C is the correct answer.
Given that, a car's odometer starts at 25 miles and for every 25 miles traveled, 1 gallon of gas is used.
What is graph?In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".
Let the number of miles traveled be y, and the gallons of gasoline used be x.
Now, the equation for the given situation is y=25x
By substituting x = 1, 2, 3, 4, 5,....we get
y = 25(1) =25
y = 25(2) =50
y = 25 (3) =75
y = 25 (4) =100
So, the coordinates to plot the graph are (1, 25), (2, 50), (3, 75) and (4, 100) and so on.
The obtained coordinate points to plot the graph are matching with graph C. Therefore, option C is the correct answer.

A green bottle holds 8 35 ounces of water. A bluebottle holds 8 67 ounces of water. Write an inequality that compares the fractions and explain which bottle holds more.
PLEASE ANSWER THIS ASSSAAAPPP!!
Answer:
Blue bottle holds more.
Step-by-step explanation:
Given:
Green Bottle = 8 3/5 = 43/5
Blue Bottle = 8 6/7 = 62/7
Now:
we can write 43/45 as;
43/5 x 7/7 = 301/35 (1)
similarly, 62/7 = 62/7 x 5/5 = 310/35 (2)
Comparing both (1) and (2),
301/35 < 310/35
:. (301 < 310)
Hence,
Blue Bottle will hold more.

Step-by-step explanation:
Value of x9x - 2 = 5x + 54
9x - 5x = 54 + 2
4x = 56
x = 14
value of y(9x - 2) + (10y + 6) = 180
(9 · 14 - 2) + 10y + 6 = 180
126 - 2 + 10y + 6 = 180
130 + 10y = 180
10y = 180 - 130
10y = 50
y = 5

why can't 3/4 be .34?
Answer:
3/4 would be .75
Step-by-step explanation:
1/4 would be .25 because .25x4=1. Because the denominator is a 4 you are trying to find a number that when multiplied 4 times would equal 1 or 4/4.
Answer:
3/4 cannot be .34 because that is not what it is equal to when converted to hundredths.
Step-by-step explanation:
The decimal 0.34 is in the value hundredths. 3/4's value when converted to hundredths is 75/100 or 0.75. We get this by multiplying 3 and 4 by the same factor that brings 4 to 100, which is 25.
So, 4*25=100(denominator), and 3*25=75(numerator). The decimal value is 0.75. Therefore, 3/4 cannot be 0.34 because the values are not the same.

at the beginning of summer, a maintenance crew refills a swimming pool at a city part. the relationship between the time in hours to fill the pool and the amount of water in the pool is proportional.
after 4 hours, the pool holds 5,200 gallons of water. b. the same crew refills a second pool as represented by the graph shown. is the second pool filled at a faster or slower rate than the first pool? explain.
Step-by-step explanation:
first pool :
in 4 hours the pool gets 5200 gallons.
that means in 1 hour it gets 5200/4 = 1300 gallons.
so, the filing rate is 1300 gallons / hour.
second pool :
we seen on the graph that
in 3 hours the pool gets 10800 gallons.
that means in 1 hour it gets 10800/3 = 3600 gallons.
so, the filing rate is 3600 gallons / hour.
therefore, the second pool fills at a much faster rate than the first pool (3600 gallons vs. 1300 gallons / hour).
