Jerome has read 50 pages of a novel. He plans to read a certain number of pages, p, each day from Monday to Friday. Which inequality shows that Jerome wants to have read at least 85 pages by the end of the day on Friday?
A. 50 + 5p ≥ 85
B. 50 + 5p ≤ 85
C. 5 (50 + p) ≥ 85
D. 5 (50 + p) ≤ 85
Answer:
There ya go
Step-by-step explanation:
If Jerome wants to have read at least 85 pages by the end of the day on Friday, then the inequality that represents the situation will be 50 + 5p≥ 85
Given that the number of pages he read each day is "p", the number of pages he will read from Monday to Friday is 5p (Monday to Friday is 5 days)If he has read 50 pages of a novel, the total number of books he has read will be 50 + 5pIf Jerome wants to have read at least 85 pages by the end of the day on Friday, then the inequality that represents the situation will be 50 + 5p≥ 85

Find the area of a sector with a central angle of 140° and a diameter of 9.6 cm. Round to the nearest tenth.
Answer:
[tex]A=28.1\ cm^2[/tex]
Step-by-step explanation:
The area of a circular sector with a central angle θ and radius r is given by:
[tex]\displaystyle A=\frac{1}{2}r^2 \theta[/tex]
Note: The angle must be in radians.
We need to find both the radius and the angle in radians.
Diameter = 9.6 cm
Radius r=Diameter/2=4.8 cm
Angle in radians= Angle in degrees*π / 180
θ = 140*π / 180 = 2.4435 rad
Now we calculate the area:
[tex]\displaystyle A=\frac{1}{2}(4.8)^2 2.4435[/tex]
[tex]\boxed{A=28.1\ cm^2}[/tex]

if you are given two coordinate points, you need to first find the?
Answer: First you need to find the first point on the coordinate graph..which would be x then y. Remember run before you jump.
Step-by-step explanation:
The first point on the coordinate graph, x, must be identified first. Remember to run before you jump.
What is the coordinate points?A set of variables that accurately depicts a position. On a graph, the first number represents the distance along, and the second number represents the distance up or down. For example, the point (12,5) is 12 units down and 5 units up.
A coordinate plane is an organizing structure for graphing and describing lines and points. The coordinate plane is made up of a vertical (y) axis and a horizontal (x) axis. The coordinate plane is divided into four quadrants. The origin is where these lines intersect (0, 0).
A pair of numbers that use the horizontal and vertical separations from the two reference axes to define a point's location on a coordinate plane. typically expressed by the x-value and y-value pair (x, y).

Carrie needs to determine the number of towels that will fit each row along the back of the shower if the back of the shower measures 6 feet long and each towel is 2/3 a foot long which equation shows how to determine the number of tiles that will fit in each row
Answer:
6 / 2/3 = 9
Step-by-step explanation:
Carrie want to find out the number of towels that will fit each row along the back of the shower
The back of the shower measures 6 ft long
Each towel is 2/3 foot long
Therefore the equation which shows how to determine the number of tile that will fit in each row is
Since 1 tile is 2/3 foot long then the number the number of tile in each row is
= 6 / 2/3
= 6 ×3/2
= 18/2
= 9

A city taxi driver charges $2 per kilometer and has a starting fee of $9. An Uber driver charges $5 per kilometer, but has no starting fee. At which distance (in kilometers) will the price of taking an Uber be equal to the price of taking a city taxi?
Answer:
2 tripsStep-by-step explanation:
first, we need to model an expression, the solve, say
let the total amount charged by taxi be y
and let the number of kilometers be x
y=2x+9
given that uber charges $5
then the number of taxi trips that will equal urber charge is
y=2x+9=5
5=2x+9
solving for x we have
2x+9-5=0
2x+4=0
2x=-4
x=-2
x=2 (x cannot be negative)
x + y = -7
-x+ 4y = 17
X=

Answer:
x= -9, y= 2
Step-by-step explanation:
5y=10
y=2
x+2=-7
x=-9
Answer:
x=-9y=2Step-by-step explanation:
[tex]x + y = - 7[/tex]
[tex] - x + 4y = 17[/tex]
[tex]y = - 7 - x[/tex]
[tex]x = 4y - 17[/tex]
[tex]y = - 7 - 4y + 17[/tex]
[tex]5y = 10 \\ y = 2[/tex]

8t=cost of "tickets"
Let's say T=7
8*7=56!
56 is the cost!
Which of the following numbers is a composite number?
OA) 13
OB) 31
OC) 49
OD) 67
Step-by-step explanation:
First you will need to know what a composite number is.
A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.
see pic below
I think it would be OC) 49
(Because that is a composite number.)

In math class, you have the following scores: 77, 82, and 73. If the
last test has a maximum of 100 points, what score do you need for
an average of 80?
Answer: 88
Step-by-step explanation: 77+82+73= 232. So you need an 80 for average. So what you have to do is 80x4 and that equals to 320. last step is to subtract 320-232 and you get 88. 77+82+73+88=320.
Answer:
Did you actually get that score???
Actually, it is none- of my buisness, but no one will judge
and probably not for the 77 and 73 your grade just go's up 2 points if you get a 100
