which of the following is a solution of the inequality y-5≥8
Answer:
See below
Step-by-step explanation:
Given: y-5≥8
Add 5 to both sides: y≥13
So any real number that is equal to 13 or above will be a solution for y.
Answer:
y>=13
Step-by-step explanation:
Let's solve the given question
y-5>=8
Add 5 to both sides
y>=8+5
y>=13
Note the >= will change only if that other side is negative
But since it is positive,it still remains
y>=13

Choose the most accurate statement based on the graph shown below.
A.) The graph is a good representation of the data.
B.) The graph is misleading because it uses 3-dimensional bars.
C.) The graph is misleading because the vertical range is too small creating the impression that differences are greater than they actually are.
Answer: A). The graph is a good representation of the data
Step-by-step explanation: The graph clearly represents that data, and it gets the point through. The graph is 3D, yet it clearly adds up to the lines therefore it is not misleading that way.
The vertical range seems fine to me, and I don't see how it being too small could create the impression that the distances are greater then they actually are.
I know its not B, because I did this question a couple minutes ago. Therefore there is nothing really misleading about this graph.

Determine the explicit formula of the following sequence -3,-18,-108...
Answer:
[tex]a_{n}[/tex] = - 3[tex](6)^{n-1}[/tex]
Step-by-step explanation:
Note the common ratio r between consecutive terms, that is
r = - 18 ÷ - 3 = - 108 ÷ - 18 = 6
This indicates the sequence is geometric with n th term ( explicit formula )
[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]
where a is the first term and r the common ratio
Here a = - 3 and r = 6, thus
[tex]a_{n}[/tex] = - 3[tex](6)^{n-1}[/tex]
The positive difference of two integers is 13. The sum of the larger number and the square of the smaller is 103. Give your solution(s) as ordered pair (larger, smaller).
Answer:
(22, 9)
Step-by-step explanation:
The positive difference of two integers is 13. The sum of the larger number and the square of the smaller is 103. Give your solution(s) as ordered pair (larger, smaller). I'll call the two integers a and b.
a - b = 13 a + b² = 103
+b +b
a = 13 + b plug this into the second equation
a + b² = 103
(13+b) + b² = 103 subtract 103 from both sides to get one side equal to zero
-103 -103
b² + b - 90 = 0 what factors (two numbers multiply) to -90 that also add up
to 1? The only two that work are -9 and 10.
(b-9)(b+10) = 0 so b-9 = 0 or b+10 = 0
+9 +9 or -10 -10
b = 9 or b = -10 but both numbers must be positive
b = 9 and a = 13 + b so a = 13 + 9 = 22

Ms. Sung budgets a maximum of $320 per month for groceries. She grocery shops 4 times a month. Which inequality can be used to find the possible values of x, the amount she can spend at the grocery store during each shopping trip?
Answer:
Less than or equal to $80
Step-by-step explanation:
If she get $320 a month and shops 4 times a month, you have to find the unit rate. This is so that you know the maximum amount of money she can spend.
320÷4=80
She can't go above $80, but she can spend any amount under $80. Than means the amount she can spend is less than or equal to $80.
The inequality that can be used to find the possible values of x is x≤80.
Maximum budget per month =$320
Number of times Ms Sung goes to a shop a month = 4
Amount spent on each shopping trip = x
What is inequality?Inequality is a statement that equates to two expressions.
So, the amount spent on 4 shopping trips = 4x
The maximum amount she can spend on all trips=$320
This means, [tex]4x\leq 320[/tex]
So, [tex]x\leq 80[/tex]
Hence, the inequality that can be used to find the possible values of x is x≤80.

The airline distance from Rome, Italy to Paris, France is 697 miles. The distance from Paris to Berlin,
Germany is 545 miles and the distance from Berlin to Rome is 734 miles. What is the angle formed from
Berlin to Paris to Rome?
Answer:
Angle Rome to Paris = 44.68°
Angle Paris to Berlin = 71.26°
Angle Berlin to Rome = 64.06
Step-by-step explanation:
See attachment for diagram illustration for this.
Let represent distance from Rome to Paris as a, distance from Paris to Berlin as b, and distance from Berlin to Rome as c.
Therefore we say
a = 697miles, b = 545miles, c = 734miles
To find the respectively angle formed from, Berlin to Paris to Rome, we will apply the cosine rule, which states that:
c² = a² + b² - 2abCosC
734² = 697² + 545² - 2(697*545)cosC
2(697*545)cosC = 697² + 545² - 734²
759739 cosC = 244078
cosC = 244078/759739
cosC = 0.3212
C = cos-¹0.3212
C = 71.26°
To get angle B, we will apply the sine rule, which states that:
a/sineA = b/sineB = c/sineC
Therefore we have
545/sineB = 734/sine71.26
= 545/sineB = 734/0.947
= 545/sineB = 734/0.947
= 545/sineB = 775.08
SineB = 545/775.08
B = sine-¹0.7032
B = 44.68°
Angle A = 180 - (B+C) angle in a triangle
A = 180 - (44.68 + 71.26)
A = 180 - 115.94
A = 64.06°
A = 64.06°
B = 44.68°
C = 71.26°
Angle Rome to Paris = 44.68°
Angle Paris to Berlin = 71.26°
Angle Berlin to Rome = 64.06°
Answer:
The Angle formed from Rome to Berlin(R)=44.68 degreesThe Angle formed from Paris to Berlin(P)=71.26 degreesThe Angle formed from Berlin to Paris(B)=64.06 degreesStep-by-step explanation:
The movement of the airplane can be represented using a triangle. In Triangle PRB, we are required to find Angles P, R and B.
Using Law of Cosines
[tex]cos R=\frac{p^2+b^2-r^2}{2pb} \\cos R=\frac{734^2+697^2-545^2}{2*734*697}\\R=arcCos\left(\frac{734^2+697^2-545^2}{2*734*697}\right)\\R=44.68^0[/tex]
Using law of Sines
[tex]\frac{r}{sin R}=\frac{p}{SIn P} \\\frac{545}{sin 44.68}=\frac{734}{Sin P} \\\text{Cross Multiply}\\545 X Sin P=734 X sin 44.68\\Sin P=\frac{734 X sin 44.68}{545} \\P=arcSin\left(\frac{734 X sin 44.68}{545}\right)\\P=71.26^0[/tex]
Now,
P+R+B=180 degrees (Sum of Angles in a Triangle)
[tex]71.26^0+44.68^0+B=180^0\\B=180^0-[71.26^0+44.68^0]\\B=64.06^0[/tex]
The Angle formed from Rome to Berlin(R)=44.68 degreesThe Angle formed from Paris to Berlin(P)=71.26 degreesThe Angle formed from Berlin to Paris(B)=64.06 degrees

Answer:
25.

The given expression is
[tex]x^2+10x[/tex]

B. $961.00

O
C. $1085.00
D. $1178.00
Answer:
$1085.00
Step-by-step explanation:
The maximum FUTA deductions for the first quarter is $1050.
What is a percentage?The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying it by 100.
The percentage change is also calculated using the same method.
In percentage change, we find the difference between the values given.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
The Federal Unemployment Tax Act (FUTA) tax rate is 6% of the first $7,000 paid to each employee per year.
So,
For person 1:
The FUTA tax is 6% of $3500 = $210.
For person 2:
The FUTA tax is 6% of $7000 = $420
Since the FUTA tax is limited to $7000 of wages per employee per year.
For person 3:
The FUTA tax is 6% of $7000 = $420.
Since the FUTA tax is limited to $7000 of wages per employee per year.
The maximum FUTA deduction would be the sum of the FUTA tax for each employee.
= $210 + $420 + $420
= $1050.
Therefore,
The maximum FUTA deductions for the first quarter is $1050.

Flippin Middle School spends $11 for every workbook it buys. At most how many workbooks can Flippin Middle school buy if it has $44 to spend?
Answer:
4
Step-by-step explanation:
4 because 11x4=44
Flippin Middle School can buy at most 4 workbooks if it has $44 to spend.
To determine the maximum number of workbooks that Flippin Middle School can buy with $44, we need to divide the total amount of money available by the cost of each workbook.
Let's denote the number of workbooks that can be bought as [tex]\( W \)[/tex], and we know that each workbook costs $11. Therefore, the total cost for [tex]\( W \)[/tex] workbooks would be [tex]\( 11W \)[/tex].
Given that the school has $44 to spend, we can set up the following inequality to find the maximum number of workbooks that can be purchased:
[tex]\[ 11W \leq 44 \][/tex]
Now, we divide both sides of the inequality by 11 to solve for [tex]\( W \)[/tex]:
[tex]\[ W \leq \frac{44}{11} \][/tex]
[tex]\[ W \leq 4 \][/tex]
Since [tex]\( W \)[/tex] must be a whole number because one cannot buy a fraction of a workbook, the maximum number of workbooks that Flippin Middle School can buy is 4.

Y=3.2x+5 what is the answer for y
Answer:
Step-by-step explanation:
Y = 3.2x + 5 is a linear function with slope 3.2 and y-intercept 5.
For any x value you choose to substitute for x, you'll obtain a unique y value. For example, if we were to substitute -3 for x, we'd get:
f(-3) = y = 3.2(-3) + 5, or y = -9.6 + 5 = -4.6
There is only one y result for each choice of x.
Y=3.2x+5 alone does not have an "answer." Again: You must pick your own x values and for each such value you must calculate y.
