Given:
A number line going from negative 2.5 to positive 2.5 in increments of 0.5.
To find:
The inequality which is true.
Solution:
Consider the number line as shown in the below figure.
We know that, on a line as we go to the left direction, the number become smaller and as we go right, the numbers become larger.
From the number line it is clear that -1.5 is on the left side of 0.5. So,
[tex]-1.5<0.5[/tex]
Hence, option A is incorrect.
-0.5 is on the left side of 0. So,
[tex]-0.5<0[/tex]
Hence, option B is incorrect.
-1.5 is on the left side of -0.5. So,
[tex]-1.5<-0.5[/tex]
Hence, option C is correct.
One half is equal to 0.5.
[tex]\dfrac{1}{2}=0.5[/tex]
Hence, option D is incorrect.

Step-by-step explanation:
Robert graduates from a technical school and finds a welding job that pays
$14 per hour. He always works at least 40 hours in a given week. When he works
overtime, he gets 1.5 times his regular hourly pay. His overtime pay can be
represented by h, the number of hours greater than 40 he works in a week.
Create an expression for the amount of money Robert earns in a week.
Use the values from the box below. Write the value(s) needed for each addend
in each space on the answer sheet.
Answer: $581
Step-by-step explanation:
given data:
Hours worked weekly(hrs) = 40
wages = $14/hr
Amount earned for overtime = 1.5 times of his hourly pay.
Solution
Amount earned for overtime
= 1.5 * $14
= $21
Amount Roberts earns in a week
= $14 * 40 + $21
= $560 + $21
= $581
Answer:
Weekly earning = 560 + 21h
Step-by-step explanation:
Given the following :
Regular Pay = $14 per hour
Work hour = atleast 40 hours per week
Overtime pay = 1.5(regular pay)
If overtime hour = h
Robert's weekly earning :
Regular pay * 40 + (overtime * 1.5(regular pay))
$14 * 40 + (h * 1.5(14))
560 + 21h
Hence,
Weekly earning = 560 + 21h

How do I solve for x, y, and z? Please help ASAP.
Answer:
x = 60 degrees, y = 120 degrees, z = 30 degrees
Step-by-step explanation:
To solve this problem, we must first recognize that the triangle on the left is an equilateral triangle. This means that all of its side lengths are equal, which in turn means that all of its angles have the same measure. Since we know the sum of the interior angles of a triangle must be 180, we can write and solve the following:
x + x + x = 180
3x = 180
x = 60 degrees
Next, we should notice that one of the 60 degree angles is supplementary with angle y, which means that their sum should equal 180 degrees. This lets us write the following equation:
y + 60 = 180
When we subtract 60 from both sides to solve, we get:
y = 120 degrees
Finally, we should notice that the triangle on the right is isosceles. This means that two of the side lengths (and thus two of the angles) are equal. This means that the unmarked angle must also measure z degrees since the side lengths corresponding to these two side lengths are equal. From this information we can write the following equation:
y + z + z = 180
If we substitute the value for y and solve, we get:
120 + 2z = 180
2z = 60
z = 30 degrees
Therefore, the correct answer is x = 60 degrees, y = 120 degrees, and z = 30 degrees.
Hope this helps!

Complete question :
Coach Right is looking at his students' running times in order to place students into running groups. He is working on forming a group that matches Jim's pace of 4 miles in 38 minutes. Which of these student times would fit into a group that runs at the exact same rate as Jim? Prax ran 6 miles in 57 minutes. Jose ran 5 miles in 45.5 minutes. Sandy ran 7 miles in 66.5 minutes. Zynep ran 3 miles in 27 minutes
Answer:
Prax and sandy
Step-by-step explanation:
Given that:
Jim's pace = 4 miles in 38 minutes
Jim's rate = Distance covered / time.
Rate = 4 / 38 = 0.1052631 miles /min
Prax ran 6 miles in 57 minutes:
Prax rate : 6miles / 57 mins = 0.1052631
Jose ran 5 miles in 45.5 minutes:
Jose's rate = 5 miles / 45.5 = 0.1098901 miles /
minute
Sandy ran 7 miles in 66.5 minutes:
Sandy's rate = 7 / 66.5 = 0.1052631 miles / minutes
Zynep ran 3 miles in 27 minutes:
Zynep's rate : 3 / 27 = 0.1111111 miles / minutes

You've decided to open a checking account. You know there are a number of differences with individual banking institutions. Name at least 3 good questions to ask to get started, and explain why knowing this information is helpful. Use complete sentences.
Answer:
Step-by-step explanation:
The three best questions to ask would be the following
What are the fees?What are the bonuses and rewards?What is the interest rate?Most bank checkings account charges fees and these fees may or may not be hidden. These can include maintenance fees, overdraft fees, balance fees, etc. and can stack up if not managed correctly. Therefore it is best to know beforehand.
One of the main things that set these accounts apart between banks are the bonuses and rewards. Some banks may offer a sign-up bonus which can be 200$ or higher when opening a new account. Others may offer higher interest rates for returning customers, or even a physical reward for spending money or depositing a certain amount into the account. These are features that set the different banks apart.
Lastly, would be the interest rate. This is especially important if you have a large sum of money that will be in the account as your money can generate more money with an interest rate. Banks may offer anywhere between 1% to 3% annual interest rate. This can be a deciding factor when choosing one bank over another.

Southside High School has a total of 1824 students. There are 84 fewer girls at Southside than boys.
Write an expression you can use to find out how many boys, b, there are at Southside.
How many boys are students at Southside High?
How many girls are students at Southside High?
Answer:
The expression you can use to find out how many boys is b + (b - 84) = 1824
There are 954 boys at Southside High School
There are 870 girls at Southside High School
Step-by-step explanation:
Assume that the number of boys in the Southside High School is b
∵ There are b boys in the Southside High School
∵ The number of girls is 84 fewer than boys
→ Subtract 84 from b to find the number of girls
∴ The number of girls in the Southside High School is (b - 84)
∵ Southside High School has a total of 1824 students
→ That means the sum of the numbers of the boys and the girls is 1824
∴ b + (b - 84) = 1824
∴ The expression you can use to find out how many boys is
b + (b - 84) = 1824
→ Add the like terms in the left side
∴ (b + b) - 84 = 1824
∴ 2b - 84 = 1824
→ Add 84 to both sides
∵ 2b - 84 + 84 = 1824 + 84
∴ 2b = 1908
→ Divide both sides by 2 to find b
∵ [tex]\frac{2b}{2}=\frac{1908}{2}[/tex]
∴ b = 954
∴ There are 954 boys at Southside High School
∵ The number of girls at Southside High School = b -84
→ Substitute b by 954
∴ The number of girls at Southside High School = 954 - 84
∴ The number of girls at Southside High School = 870
∴ There are 870 girls at Southside High School
Un apostador pierde en su primer juego el 30% de su dinero, en el segundo juego pierde el 50% de lo que perdió; finalmente en el tercer juego pierde el 40% de todo lo que ha perdido quedándole 37 soles para seguir apostando. Dar como respuesta el dinero que el apostador tenía al principio menos su 75%
Responder:
26,62
Explicación paso a paso:
Sea x el dinero original que tenía el jugador:
si un jugador pierde en su primer juego el 30% de su dinero, la cantidad perdida será;
[tex]= 30/100 \ of \ x\\= 0.3x[/tex]
Si en el segundo juego pierde el 50% de lo que perdió, entonces la cantidad perdida en el segundo juego será:
[tex]= 50/100 \ of \ 0.3x\\= 0.5 \times 0.3x\\= 0.15x[/tex]
Si en el tercer juego pierde el 40% de todo lo que ha perdido, la cantidad perdida en el tercer juego será:
[tex]=\frac{40}{100} \ of \ (0.3x+0.15x) \\= 0.4(0.45x)\\= 0.2025x[/tex]
Si la cantidad que le queda para seguir apostando es de 37 soles, entonces para calcular la cantidad original que tiene, sumaremos toda la cantidad perdida y la cantidad restante y equipararemos la cantidad original x como se muestra:
0,3x + 0,15x + 0,2025x + 37 = x
0,6525x + 37 = x
x-0,6525x = 37
0,3475x = 37
x = 37 / 0,3475
x = 106,48
La cantidad que tenía originalmente era de 106,48
75% de 106,48
= 75/100 * 106,48
= 0,75 * 106,48
= 79,86
Tomando la diferencia entre su monto original y su 75% será:
[tex]= 106.48-79.86\\= 26.62[/tex]

C. Angle MNP
Step-by-step explanation:
Check the corresponding equal sides with congruent angles
Answer: Third choice. [tex]\angle MNP[/tex]
=======================================================
Explanation:
We want to find something congruent to angle ABC.
With angle ABC, we have
A firstB secondC thirdThe order is important.
Looking at the triangle on the right, we see that
angle A has three arc marksangle B has one arc markangle C has two arc marksThe sequence of arc markings can be written as 3,1,2
Now focus your attention on the triangle on the left. Start with the triple arc angle, move to the single arc angle, then go to the double arc angle. You should trace out M, N then P in that exact order.
Therefore [tex]\angle ABC \cong \angle MNP[/tex]
Note how M is first, N is second, then P is third.
This lets us form these pairs of congruences
A = M (first letters; triple arc marking)B = N (second letters; single arc marking)C = P (third letters; double arc marking)Verify 1) x³+y³=(x+y)(x²-xy+y²)
2) x³-y³=(x-y)(x²+xy+y²)
using some non-zero positive integers and check by actual multiplication. can you call these as identities?
x³ + y³ = (x + y)(x² - xy + y²)
x³ - y³ = (x - y)(x² + xy + y²).
Proof for 1st Identity :
★ x³ + y³ = x (x² - xy + y²) + y(x² - xy + y²)
⟶ x³ + y³ = x³ - x²y + xy² + x²y - xy² + y³
⟶ x³ + y³ = x³ + y³
Proof for 2nd identity :
★ x³ - y³ = x(x² + xy + y²) - y(x² + xy + y²)
⟶ x³ - y³ = x³ + x²y + xy² - x²y - xy² - y³
⟶ x³ - y³ = x³ - y³
For example,Let us assume that,
x = 1
y = 2
So,
✯ x³ + y³ = 1³ + 2³
⟹ (x + y)(x² - xy + y²) = 1 + 8
⟹ (1 + 2)(1² - (1)(2) + 2²) = 9
⟹ 3 * (1 - 2 + 4) = 9
⟹ 3 * 3 = 9
⟹ 9 = 9
✯ x³ - y³ = 1³ - 2³
⟹ (1 - 2) * (1² + (1)(2) + 2²) = 1 - 8
⟹ ( - 1) * (1 + 2 + 4) = - 7
⟹ ( - 1) * (7) = - 7
⟹ - 7 = - 7
Thus , they can be called as identities/formulae as they are very useful in finding the value of a certain equation or an expression easily.
I hope it will help you.

You are a contractor and charge $90 for a site visit plus an additional $24 per hour for each hour you spend working at the site. Write and solve an equation to determine how many total hours you have to work to earn $810 working at two separate work sites. Let the number of hours you work be y.
Answer:
x=29.66hrs
Step-by-step explanation:
Firstly, we can model the equation for the total cost as
Let y be the total cost
Let x be the number of hours
Y=98+24x
Also, given that you have earned $810
We can substitute Y=810 and solve for x
810=98+24x
810-98=24x
712=24x
Dividing both sides by 24
712/24=x
x=29.66hrs
Let $f(x) = 2x - 3$ and $g(x) = x + 1$. What is the value of $f(1 + g(2))$?
Answer:
The value of f(1 + g(2)) is 5
Step-by-step explanation:
Let us solve the question
∵ f(x) = 2x - 3
∵ g(x) = x + 1
We need to find the value of f(1 + g(2))
That means we will replace x in f(x) by 1 + g(2)
→ g(2) means substitute x in g by 2
∵ g(x) = x + 1
∵ x = 2
∴ g(2) = 2 + 1
∴ g(2) = 3
∵ x of f = 1 + g(2)
∵ g(2) = 3
∴ x of f = 1 + 3
∵ x of f = 4
→ To find f(1 + g(2)) substitute 1 + g(2) by 4
∵ f(x) = 2x - 3
∵ x = 4
∴ f(4) = 2(4) - 3
∴ f(4) = 8 - 3
∴ f(4) = 5
∴ f(1 + g(2)) = 5
