City R has a temperature of −2 °F. City S has a temperature of −6 °F.
Use the number line shown to answer the questions:
Part A: Write an inequality to compare the temperatures of the two cities. (3 points)
Part B: Explain what the inequality means in relation to the positions of these numbers on the number line. (4 points)
Part C: Use the number line to explain which city is warmer. (3 points)
part a: –2°F > –6°F
part b: the inequality is representing the temperatures of city R and city S, comparing the difference in their temperatures.
part c: (marking city R at –2 on the number line and marking city S at –6 on the number line), using the number line to show the values of the city temperatures, city R is warmer because it is closer to 0 while city S is farther from zero and in the case that these are negative temperatures, the temperature closest to zero is the warmest.
7/3 x (2/3 - 2/9) =
I need help with this and I've looked for websites for help, no luck. Please help
Answer:
1 1/27 = 28/27
Step-by-step explanation:
First you evaluate your parenthesis, and to do that you need to find the Least Common Denominator of 2/3 and 2/9. The least common denominator would be 9. 3 x 3 = 9 so you multiply 2 x 3 = 6. 6/9 - 2/9 = 4/9. 7/3 x 4/9
7 x 4 = 28
3 x 9 = 27
28/27 = 1 1/27
Hey there!
7/3 * (2/3 - 2/9)
= 7/3 * 4/9
= 7(4) / 3(9)
= 28 / 27
≈ 1 1/27
Therefore, the answer should be:
28 / 27
OR
1 1/27
Either should work because they are both equivalent to each other.
Good luck on your assignment & enjoy your day!

Help. Where do I put the dot, should it be opened or closed, and what direction should the line face?
Answer: 5 with an open circle facing the right.
Step-by-step explanation:
First: you need to know the difference between closed and open circles. Closed means less than or equal to/ greater than or equal to while an open circle just means less than/ greater than.
Second: To know if it will be facing left or right is very simple. It is just if the number is increasing or decreasing in your problem. If increasing it goes right if decreasing it goes left. In this case, the number increases each day so it will face the right.
Third: To start the problem you subtract the number of shells she has already (34) by how many she needs (100) which is 66. then divide 66 by the number of seashells they get a day (12) which would give you 5.5
Fourth: I'm going to guess that you can't do decimals on the graph so all you have to do is put an open circle with the arrow facing the right meaning everything after this point, not including the number it is on.
Answer:
d ≥ 7
Step-by-step explanation:
A closed dot means you CAN use the number in the equality (greater than and equal to or less than and equal to). An OPEN dot means it's just greater than or less than, no equal to. Positive numbers GROW to the right so if the line is going that way it means greater than or greater than and equal to. The same is true for the left side. The left side makes numbers get SMALLER which means less than or less than and equal to. Your problem has a closed dot and an arrow to the right so the inequality is d ≥ 7.
Show how to use substitution to solve the following system of equations. Write the solution as an ordered pair.
4x - y = 10
y = 2x - 2
*Hint: Substitute 2x-2 for ‘y’ in the first equation: 4x - (2x - 2)= 10
Then solve for ‘x’. Use your answer for 'x' to solve for 'y'.
Include in Your Answer:
The work used to solve for 'x'.
The work used to solve for 'y'.
Your final answer written as an ordered pair (x , y)
Answer:
(6, 10)
Step-by-step explanation:
Step 1: Substitute 2x-2 for ‘y’ in the first equation:
4x - (2x - 2)= 10
Step 2: Combine like terms
2x -2 =10
Step 3: Add 2 to both sides of the equation
2x = 12
Step 4: Divide both sides by 2
x= 6
Now substitute x=6 into any of the equations given, I chose the bottom one.
Step 5: Plug in x=6 and solve
y= 2(6) -2
y= 12-2
y= 10
Step 6: Write your answer as an ordered pair (x, y).

Answer:
1,256 dm^2 and 400π dm^2
Step-by-step explanation:
The circumference is equal to 2pi times the radius. So 40pi=2pi times the radius so the radius is 20. The area of a circle is pi times the radius squared or 400pi and if using 3.14 for pi this would be 1,256 dm^2
pls answer I will give brainliest
Answer: 108 ft³
Step-by-step explanation:
V= 4/3πr³
Facts:
Pi= 3
Diameter = 6
Step1; find the radius
Diameter is the length acaross the whole circle, but the radius is just 1/2 the circle. Therefore, if the diameter is 6, then the radius can be found by finding 1/2 of 6.
1/2 of 6= 1/2x6= 3.
R= 3
Step 2: Plug in the numbers (into the formula)
PEMDAS
(exponents go first)
(then multiply from left to right)
V= 4/3πr³
V= 4/3x3x3³
V= 4/3x3x (3x3x3)
V= 4/3x3x27
V= (4/3x3) x 27
V= 12/3x27
V= 4x27
V= 108
Volume= 108 ft³

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. If Hugh bought 3 magazines, how many books did he buy?
The equation that models the problem is 3.95m + 8.95b = 47.65, where m is the number of magazines and b is the number of books.
__ books
Answer:
4 books
Step-by-step explanation:
Our problem here is:
[tex](3.95)3+8.95b=47.65[/tex]
So we have to find B, and that will be our answer (the number of books).
1. Simplify the expression
[tex]3.95\cdot 3+8.95x=47.65[/tex]
Combine like terms:
[tex]11.85+8.95x=47.65[/tex]
2. Group all constants on the right side of the equation
[tex]11.85+8.95x=47.65[/tex]
Subtract from both sides:
[tex]11.85+8.95x-11.85=47.65-11.85[/tex]
Group like terms:
[tex]8.95x+11.85-11.85=47.65-11.85[/tex]
Simplify the arithmetic:
[tex]8.95x=47.65-11.85[/tex]
Simplify the arithmetic:
[tex]8.95x=35.8[/tex]
3. Isolate the x
[tex]8.95x=35.8[/tex]
Divide both sides by 8.95:
[tex]\frac{8.95x}{8.95}=\frac{35.8}{8.95}[/tex]
Simplify the arithmetic:
[tex]x=\frac{35.8}{8.95}[/tex]
Simplify the arithmetic:
[tex]x=4[/tex]

On a piece of paper, use a protractor to construct a triangle with angle measures of 40° and 70°.
Which statements about this triangle are true?
Select all correct answers.
All sides have different lengths.
It is an acute triangle.
It is an obtuse triangle.
The third angle measures 110°.
The third angle measures 70°.
Two sides have the same length.
Answer:
It is an acute triangle.
Two sides have the same length.
The third angle measures 70°.
Step-by-step explanation:
It is an acute triangle because all triangles are less than 90°.
Two sides have the same length because since we know that two angles, which would be the base angles are the same, then triangle must be isosceles.
180°-(40°+70°)= 110°

Calculating Perimeter
Answer: P= 2640 dam
or 264 hm
or 26.4 km
Step-by-step explanation:
See picture of all side values in the three measurement forms
Answer: I think this is right but I'm not 100 percent sure
26.4 km, 264 hm, 2640 dam
Step-by-step explanation:
Well, permitter is adding all lengths together.
Which is 5 km + 62 hm + 62 hm + 900 dm
Assuming hm stands for Hectometer, I will divide 62/10 = 6.2
Now we are left with the equation 5 km + 6.2 km + 6.2 km + 900 dam
Since 100 dm = 1 km, we will divide 900 dm by 100 which is 9 km
Lastly, we are left of with:
5 + 6.2 + 6.2 + 9 = 26.4 km
Now I will quickly covert everything into the other 2 measurements
26.4 km = 264 hm (10x)
26.4 km = 2640 dam (100x)

The contents of two boxes are shown below. What is the probability of drawing a vowel from box 1 and an even number from box 2?
Box 1: A, B, C, D, E
Box 2: 1, 2, 3, 4, 5, 6, 7, 8, 9
PLEASE SHOW ALL YOUR WORK AND GET 30 POINTS !!!!!!! THANK YOU
Answer:
vowel = 2/5
even number = 4/9
Step-by-step explanation:
vowel:
total of all letters in the box= 5
cound total number of vowels in the box = 2
[tex]\frac{2}{5}[/tex] because out of the 5 letters there is 2 vowels so overall you have a [tex]\frac{2}{5}[/tex]chance of pulling out a vowel.
Same logic for the even numbers one.
Even numbers:
total amount of numbers in the box: 9
total amout of even numbers: 4
[tex]\frac{4}{9}[/tex] because you have 9 numbers in total and you want the chnce of finding an even number. That means you need to put the amout of even numbers on top of the fraction and the total amount below.
OVERALL:
simple way of remembering it is:
p = total amout of the thing you want the probability of finding (in this case even numbers or vowels)
t = total amout of all options in the box (or any container)
