Answer:
r + c ≤12
r > 3
c > 2
Step-by-step explanation:
Jennifer is putting together a selection of flowers that has at most 12 flowers in it.
r = number of roses she uses
c = the number of carnations
At also means Less than or equal to.
It is represented by ≤
She is choosing either roses or carnations. She wants to pick at least three roses
r > 3
and at least two carnations.
= c > 2
Therefore, the system of inequality that represents this scenario is written as:
r + c ≤ 12
r > 3
c > 2
A set of data has 50 observations. How many classes would you recommend?
Answer:
6 classesStep-by-step explanation:
If k is the number of classes and n is the number of observations, then for number of classes we should select the smallest k such that 2^k > n.
We have n = 50 and:
2^5 = 32 < 502^6 = 64 > 50As per above described 2 to k rule, we are taking k = 6.
So 6 classes should be used.

Using the diagram below, which of the following proportionality statements are true? Select all that apply.
Answer:
The proportionality statement which is true is;
(B) [tex]\dfrac{G'H'}{GH} = \dfrac{E'F'}{EF}[/tex]
Step-by-step explanation:
From the diagram, given that the two pentagons are similar, we have;
1. [tex]\dfrac{DH}{D'H'} = \dfrac{EF}{E'F'}[/tex]
2. [tex]\dfrac{DE}{D'E'} = \dfrac{GH}{G'H'}[/tex]
By similarity of the two polygons, we can get the following statements from among the options;
3. [tex]\dfrac{G'H'}{GH} = \dfrac{E'F'}{EF}[/tex]
Therefore, the proportionality statement which is true from the given is the statement;
[tex]\dfrac{G'H'}{GH} = \dfrac{E'F'}{EF}[/tex]
if PQ and PR are tangent to circle S,find PQ
Answer:
From one point, you can draw two tangents to a circle. These two tangents will be equal.
Step-by-step explanation:
7x - 24 = 57 - 2x.
Rearrange the numbers (by adding 2x and 24 on both sides), we get:
7x+2x = 57 + 24
9x = 81.
x = 9.
Length of PQ = 57-2x = 57 - 18 = 39
If PQ and PR are tangent to circle S, then the value of PQ is 39.
What is tangent?"A line that touches the circle at a single point is known as a tangent to a circle."
What is circle?"A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre."
P is the exterior point of a circle.
PQ and PR are the tangents to circle S.
According to theorem,
The lengths of the tangents drawn from a same external point to a circle are always equal.
7x - 24 = 57 - 2x
7x + 2x = 57 + 24
9x = 81
x = 9
PQ = 7x - 24
PQ = 7(9) - 24
PQ = 63 - 24
PQ = 39
Hence, the value of PQ is 39.

What is the equation of the line in slope intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = -x
Step-by-step explanation:
(0, 0) and ( -100, 100)
m= (y2-y1)/(x2-x1)
m=(100-0)/( -100 -0)
m = 100/ -100
m = -1
y - y1 = m(x - x1)
y - 0 = -1(x - 0)

A builder was building a fence. In the moring he worked 2/5 of an hour. In the afternoon he wirked for 9/10 of an hour how many times as long in the morning did he work in the afternoon
Answer:
2 1/4 times
Step-by-step explanation:
A builder was building a fence. In the moring he worked 2/5 of an hour. In the afternoon he wirked for 9/10 of an hour. how many times as long in the morning did he work in the afternoon
Note that:
1 hour = 60 minutes
In the moring he worked 2/5 of an hour.
= 2/5 × 60 minutes
= 24 minutes
In the afternoon he worked for 9/10 of an hour
Hence:
9/10 × 60 minutes
= 54 minutes
How many times as long in the morning did he work in the afternoon?
This is calculated as number of minutes worked in the afternoon ÷ Number of minutes worked in the morning
= 54 minutes/24 minutes
= 2 6/24
= 2 1/4 times
Ian went to a music store to buy a guitar. The guitar which he picked out was $350. He found out that there was a sale that day and all guitars were 20% off.

In circle H with m \angle GHJ= 34m∠GHJ=34 and GH=11GH=11 units, find the length of arc GJ. Round to the nearest hundredth
Answer:
2.75unitsStep-by-step explanation:
Find the diagram attached
The length of an arc is expressed as shown;
[tex]L = \frac{\theta}{360} * 2 \pi r[/tex]
r is the radius = length of GH
r = GH = 11units
m<GHJ = 34 degree
Substitute the given parameters into the equation given;
[tex]L = \frac{\theta}{360} * 2 \pi r[/tex]
[tex]L = \frac{34}{360} * 2(3.14)(11)\\ L = \frac{34}{360} * 29.08\\L = \frac{988.72}{360}\\L = 2.75 units\\[/tex]
Hence the length of the arc to the nearest hundredth is 2.75units

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $8 and each adult ticket sells for $10.50. The auditorium can hold a maximum of 105 people. The drama club must make at least $990 from ticket sales to cover the show's costs. If 65 adult tickets were sold, determine the minimum number of student tickets that the drama club must sell in order to meet the show's expenses.
Answer:
You need to sell 39 Student tickets minimum to be able to cover the cost over all.
Step-by-step explanation:
If they sell 65 adult tickets, then you have to do 65 x 10.50 = $682.5
with that in mind you will take 308 + 682.5 because that equals 990.5 that would be the minimum amount but you would need to to take 39 x 8 to get 312 because 38 x 8 is 304 so that isn't enough.
