[tex]x^{2} x^{2} \sqrt{x} \neq \lim_{n \to \infty} a_n \left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right][/tex]
(Geometry): find x.
20x + 1 = 720
20x = 719
x = 35.95
Your answer: 35.95
Proof:
(5(35.95))+(35.95-10)+(3(35.95)+5)+(2(35.95)-2)+(5(35.95)+6)+(4(35.95)+2) = 720
X=
(-6x+125) (11x + 6)
9514 1404 393
Answer:
x = 7
Step-by-step explanation:
The base angles of an isosceles triangle are congruent, so ...
11x +6 = -6x +125
17x = 119 . . . . . . . . . add 6x-6 to both sides
x = 7 . . . . . . . . divide by 17

Select the inequality that match the situation:
A school fundraiser has a minimum target of $500. Faculty have donated $100 and there
are 12 student clubs that are participating with different activities. How much money
should each club raise to meet the fundraising goal?
12x - 100 > 500
12x +100 > 500
12x- 100 > 500
12x + 100 > 500
12x - 100 < 500
12x + 100 < 500
Answer:
Each student club must contribute $ 33.33 in order to meet the fundraising goal.
Step-by-step explanation:
Given that a school fundraiser has a minimum target of $ 500. Faculty have donated $ 100 and there are 12 student clubs that are participating with different activities, to determine how much money should each club raise to meet the fundraising goal, the following calculation must be performed:
(500 - 100) / 12 = X
400/12 = X
33,333 = X
Thus, each student club must contribute $ 33.33 in order to meet the fundraising goal.

I am working on this subject too. I'm gonna get a calculator and help you. The answer is actually 14
through: (-3,-4) and (0,4)
Answer:
The slope = 8/3
Step-by-step explanation:
Let's find the slope between your two points.
(−3,−4);(0,4)
(x1,y1) = (−3,−4)
(x2,y2) = (0,4)
Use the slope formula:
m= y2−y1 / x2−x1
= 4 − −4 / 0 − −3
= 8/3
Answer:
m = 8/3

Jane drew a point that was 2 units to the right of the y-axis and 5 units above the x-axis. What is the ordered pair for this location?
The ordered pair for this location is (_,_ ).
Answer:
(-2,5)
Step-by-step explanation:
because 2 units to left of the y axis makes it a negative and it makes it on the z axis so you get negative 2 then 5 units above the x axis gets just 5 so that's how you get (-2,5)
A stone pyramid in Egypt has a square base that measures 160 m on each side. The height is 91 m. What is
the volume of the pyramid?
Volume = (base area x heigh)/3
base area = 160m x 160m
base area = 25600 m²
Volume = (25600 m² x 91 m) / 3
Volume = 776533.333 m³
Answerthe volume is 776533.333 m³
A person on a moving sidewalk travels 72 feet in 9 seconds. The moving sidewalk has a length of 240 feet. How long will it take to move from one end to the other?
Answer:
30 seconds
Step-by-step explanation:
Speed of person :
72 feets in 9 seconds
Distance = 72 feets ; time = 9 seconds
Speed = distance / time
Speed = 72 / 9 = 8 ft/s
Length of sidewalk = 240 feets
Time it takes to move from one end to the other :
Time = distance / speed
Time = 240 feets / 8 feets /sec
Time taken = 30 seconds
The radius of a cylindrical water tank is 4 ft, and its height is 6 ft, what is the volume of the tank?
Answer:
96π cu ft.
Step-by-step explanation:
V = Bh B = area of the base h = height
The base is a circle, so [tex]B = \pi r^{2} = \pi 4^{2} = 16\pi[/tex]
V = 16π(6) = 96π cu ft.
The volume of the cylinder is 301. 6 cu. ft.
What is the volume of the cylinder?[tex]V=\pi \times r^2\times h[/tex]
where r is the radius of the cylinder and h is the height of the cylinder
For given question,
The radius of a cylindrical water tank is 4 ft, and its height is 6 ft,
[tex]\Rightarrow r=4~ft,~h=6~ft[/tex]
We need to find the volume of the cylinder.
Using the formula of the volume of the cylinder,
[tex]\Rightarrow V=\pi \times r^2\times h\\\\\Rightarrow V=\pi \times 4^2\times 6\\\\\Rightarrow V=\pi \times 16 \times 6\\\\\Rightarrow V =301.6~~cu.ft.[/tex]
Therefore, the volume of the cylinder is 301. 6 cu. ft.

Answer:
y = - x + 3
or
x + y = 3
Step-by-step explanation:
Line is passing through the points (3, 0) & (0, 3)
y-intercept (b) = 3
Slope of the line (m) = (3 - 0)/(0 - 3) = 3/(-3) = - 1
Now, required equation of line is given as:
y = mx + b
y = - 1*x + 3
y = - x + 3
or
x + y = 3
