Did she graph the system correctly?
O) No, Norah did not graph correctly.
O) Yes, Norah is correct.
Answer:
Y=2x+ 5y
Y<(less than or equal to) 36
X+y>( greater than or equal to) 3
Step-by-step explanation:
So to find one variable in the equation such as finding the amount of roses or carnations, you would have to do system of equations. Some ways of using system of equations is to use substitution, elimination, or graphing.

The explicit formula for an arithmetic sequence is an = 20 + (n − 1)(2). What is the 200th term?
Answer:
[tex]a_{200}=418[/tex]
Step-by-step explanation:
The explicit formula for an arithmetic sequence is given by :
[tex]a_n=20+(n-1)2[/tex] ...(1)
We need to find the 200th term of the sequence.
Put n = 200 in equation (1)
[tex]a_{200}=20+(200-1)2\\\\=20+199\times 2\\\\=418[/tex]
So, the 200th term of the sequence is 418.

2. A ladder 20 feet long leans a vertical building. If the bottom of the ladder slides away from the building
horizontally at a rate of 2 ft/sec, how fast is the ladder sliding down the building when the top of the
ladder is 12 feet above the ground?
-8/3 ft/s
Step-by-step explanation:We are given:
distance of the top of the ladder from the ground (h) = 12 ft
height of the ladder = 20 ft
rate of change of the distance of the base of ladder from the wall (dx/dt):
2 ft/s
Finding the distance of the base of the ladder from the wall:
From the Pythagoras's Theorem, we know that:
hypotenuse² = height² + base²
replacing the given values
20² = 12² + x²
400 = 144 + x²
x² = 256 [subtracting 144 from both sides]
x = 16 ft [taking the square root of both sides]
The rate of change of the height of the Ladder from the ground:
We know that:
h = 12 ft
([tex]\frac{dh}{dt}[/tex]) = ?
x = 16 ft
([tex]\frac{dx}{dt}[/tex]) = 2 ft/s
According to the Pythagoras's Theorem:
20² = x² + h²
differentiating both sides with respect to time
[tex]\frac{d(400)}{dt} = \frac{d(x^{2} + h^{2})}{dt}[/tex]
[tex]0 = \frac{d(x^{2})}{dt} + \frac{d(h^{2})}{dt}[/tex]
[tex]0 = \frac{d(x^{2})}{dx}(\frac{dx}{dt}) + \frac{d(h^{2})}{dh}(\frac{dh}{dt})[/tex]
[tex]0 = 2x(\frac{dx}{dt}) + 2h(\frac{dh}{dt})[/tex]
replacing the variables
[tex]0 = 2(16)(2) + 2(12)(\frac{dh}{dt})[/tex]
[tex]0 = 64 + 32(\frac{dh}{dt})[/tex]
[tex]-64 =32(\frac{dh}{dt})[/tex] [subtracting 64 from both sides]
[tex]\frac{-64}{32} =(\frac{dh}{dt})[/tex] [dividing both sides by 32]
[tex]\frac{dh}{dt} = \frac{-8}{3} ft/s[/tex]
Hence, the ladder will slide down at a speed of 8/3 feet per second

A basketball that sold for $65 is marked up to $70.20. What is the percent of the markup?
Answer:
8%
Step-by-step explanation:
70.20−65.00=5.20
(5.20/65.00)×100=8
Answer:
8% markup
Step-by-step explanation:
65x=70.20
x = 70.20/65
x = 1.08
to get it as a percentage, you multiply 1.08*100=108%
this means that there is an 8% markup

Step-by-step explanation:
There are 550 people at the school
carnival.
Part A
If 385 of the people are students, what
percentage of the people at the school
carnival are students?
Part B
If 30% of all the people at the carnival are
on a ride, how many people are on a ride?
Helppppp me I have 30 minutes
Answer: part A is 20%
Part B is 165
Step-by-step explanation:
Part B: 30% x 550= 165
The percentage of people who are students will be 70%. And the number of people who are on the ride will be 165.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
There are 550 people at the school carnival. If 385 of the people are students, then the percentage is calculated as,
P = (385 / 550) x 100
P = 70%
If 30% of all the people at the carnival are on a ride. Then the number of people on a ride will be given as,
⇒ 30% of 550
⇒ 0.30 x 550
⇒ 165 people
The percentage of people who are students will be 70%. And the number of people who are on the ride will be 165.
More about the percentage link is given below.

Last Friday Cicely had $22.50. Over the weekend she received some money for
cleaning out the attic. She now has $32. Which equation represents how much
money she received?
Answer:
It should be $32 - $22.50.
Step-by-step explanation:
This is because we're trying to find out the amount she received. So we will subtract the amount she already has from how much she now has to figure out how much she received. 32 - 22.50 = 9.50.
