Answer:
2x < 6
x < 3
Step by step:
2x < 6
x < 3
Answer:
To get rid of the coefficient of x we need to divide the inequality by 2 on both sides which gives us x < 3

To create an image, Figure C is going to be translated 2 units to the left, reflected across the y-axis, and rotated 270° clockwise about the origin. What must be true about Figure C and its image?
Answer:
BRO THE IMAGE FORMED IS CONGRUENT
Step-by-step explanation:
Answer:
They are congruent
Step-by-step explanation:
Figure C will still stay the same shape and size because there was no dilation involved in the process. The image of Figure C will be in quadrant 1 and rotated 270° clockwise. Congruent means it is the same shape and size. So our answer is "They are congruent".
Will a 9/32 inch diameter pin fit into a reamed hole with a diameter of 0.278 inch? (Do not round off your answer and express it in fraction
form)
Answer: Yes
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a circle = π r^2
Reamed hole area = π 0.278^2= 0.242794846
Pin Area: π ([9/32]/2)^2= 0.062126221
Diameter = 2 radius
Radius = diameter/2
Since
Hole Area > pin area
The pin will fit into the reamed hole.

Which of the given line segments is congruent to AB?
Answer:
VW
Solution:
VW is congruent to AB, because they have the same length.
The line segment VW is congruent to AB.
What are congruent line segments?A pair of line segments are said to be congruent when the lengths of both the line segments are equal.
How do we solve the given question?To solve the given question, we compare each line segment with AB to find its congruent pair.
PQ: PQ > AB, so its not congruent to AB.RS: RS < AB, so its not congruent to AB.TU: TU < AB, so its not congruent to AB.VW: VW = AB, so its congruent to AB.∴ We can say that VW is the line segment congruent to AB.

Find the value of x if A, B, and C are collinear points and B is between A and C. AB=2x,BC=x−2,AC=28
Answer:
x = 10
Step-by-step explanation:
Data
AB=2xBC=x−2AC=28Given that A, B, and C are collinear points and B is between A and C, then the addition of the measure of segments AB and BC must be equal to the measure of segment AC, that is:
AB + BC = AC
Replacing with data:
2x + (x - 2) = 28
3x - 2 = 28
3x = 28 + 2
x = 30/3

2. Mr. Smith paid $36.36 for a carpet. This amount includes a tax of 10%. What was the cost of the carpet before tax?
Answer:
for the first question the total bill is $35.524
for the 2nd question the answer is $36.36 = 110%.
$36.36 ÷ 1.1 = $33.054
(the five and the four are recurring)

Bill needs to edge his yard with the dimensions in the shape below. What distance will he have walked after completing his edging? Round your answer to one decimal place. Do not include units in your answer.
Answer:
37.8
Step-by-step explanation:
The distance is the addition of all sides of the figure. Then, we need to find the length of the diagonal (d). To do that we have to make a right triangle with height (h) = 5 m. Given that the top length is 12 m and the bottom length is 15 m, the base (b) of the triangle is 15 - 12 = 3 m
Using Pythagorean theorem:
d² = h² + b²
d² = 5² + 3²
d = √34
d = 5.8 m
Therefore, the distance he will have walked is 5.8 + 12 + 15 + 5 = 37.8 meters

The average weight of 7 potted plants is 23 pounds. An 8th potted plant is added to the pallet,
and the average weight increases to 25 pounds. What was the weight, in pounds, of the 8th
plant?
Answer:
The weight of the 8th plant is 39lb
Step-by-step explanation:
Given:
Average Weight of 7 plants = 23lb
Average Weight of 8 plants = 25lb
Required:
Weight of the 8th plant
To solve this, the total weight of the initial 7 plants need to be calculated;
[tex]Average = \frac{Sum-of-weights}{Number-of-Plants}[/tex]
Substitute 23 for Average and 7 for Number of plants
[tex]23 = \frac{Sum-of-weights}{7}[/tex]
Multiply both sides by 7
[tex]7 * 23 = \frac{Sum-of-weights}{7} * 7[/tex]
[tex]161 = Sum-of-weights[/tex]
Hence, the 7 plants weigh 161
Represent the weight of the 8th plant with E
When the 8th plant is added;
The sum of the weight becomes 161 + E
And the number of plants becomes 8
The average is calculated as thus
[tex]Average = \frac{Sum-of-weights}{Number-of-Plants}[/tex]
[tex]25 = \frac{161 + E}{8}[/tex]
Multiply both sides by 8
[tex]8 * 25 = \frac{161 + E}{8} * 8[/tex]
[tex]200 = 161 + E[/tex]
Subtract 161 from both sides
[tex]200 -161 = 161 - 161 + E[/tex]
[tex]39 = E[/tex]
Reorder
[tex]E = 39[/tex]
Hence, the weight of the 8th plant is 39lb

[tex]x - \frac{2}{3}x - \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x[/tex]
Answer:
[tex]x = \frac{-5}{3}[/tex]
Step-by-step explanation:
Given
[tex]x - \frac{2}{3}x - \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x[/tex]
Required
Simplify
[tex]x - \frac{2}{3}x - \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x[/tex]
Add [tex]\frac{1}{2}[/tex] to both sides
[tex]x - \frac{2}{3}x - \frac{1}{2} + \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x + \frac{1}{2}[/tex]
[tex]x - \frac{2}{3}x = \frac{1}{3} + \frac{5}{6}x + \frac{1}{2}[/tex]
Subtract [tex]\frac{5}{6}x[/tex] from both sides
[tex]x - \frac{2}{3}x - \frac{5}{6}x= \frac{1}{3} + \frac{5}{6}x + \frac{1}{2} - \frac{5}{6}x[/tex]
[tex]x - \frac{2}{3}x - \frac{5}{6}x= \frac{1}{3} + \frac{1}{2} + \frac{5}{6}x- \frac{5}{6}x[/tex]
[tex]x - \frac{2}{3}x - \frac{5}{6}x= \frac{1}{3} + \frac{1}{2}[/tex]
Take LCMs
[tex]\frac{6x - 4x -5x}{6}= \frac{2+3}{6}[/tex]
[tex]\frac{-3x}{6}= \frac{5}{6}[/tex]
Multiply both sides by 6
[tex]6 * \frac{-3x}{6}= \frac{5}{6} * 6[/tex]
[tex]-3x= 5[/tex]
Divide both sides by -3
[tex]\frac{-3x}{-3}= \frac{5}{-3}[/tex]
[tex]x = \frac{5}{-3}[/tex]
[tex]x = \frac{-5}{3}[/tex]

The mean annual salary paid to all employees in a company was 1500 Kenya pounds The mean annual salaries paid to male and female employees were 1560 Kenya pounds and 1260 Kenya pounds respectively. Determine the percentages of males and females employed by the company.
Answer:
[tex]Male = 80[/tex]%
[tex]Female = 20%[/tex]%
Step-by-step explanation:
Given
Annual Mean Salary = 1500
Annual Mean Salary (Male) = 1560
Annual Mean Salary (Female) = 1260
Required
Percentage of male and female employed
Represent male by m and female by 4
So, total employees = m + f
The mean of an observation is calculated as thus;
Mean = Summation of observation divided by number of observations
For Male:
Annual Mean = Total Salary/Number of males
Recall that Annual Mean = 1560
Number of males = m;
The formula becomes
[tex]1560 = \frac{TotalSalary}{m}[/tex]
Multiply both sides by m
[tex]1560 * m = \frac{TotalSalary}{m} * m[/tex]
[tex]1560m = TotalSalary[/tex]
For Female:
Annual Mean = Total Salary/Number of females
Recall that Annual Mean = 1260
Number of females = f;
The formula becomes
[tex]1260 = \frac{TotalSalary}{f}[/tex]
Multiply both sides by f
[tex]1260 * f = \frac{TotalSalary}{f} * f[/tex]
[tex]1260f = TotalSalary[/tex]
Total Annual Salary = Annual Salary of Male + Annual Salary of Female
Total Annual Salary = 1560m + 1260f
The mean annual salary is calculated as thus;
Mean Annual Salary = Total Annual Salary/Total Employees
Recall that Total Employees = m + f and Mean Annual Salary = 1500
So, the formula becomes
[tex]1500 = \frac{1560m + 1260f}{m+f}[/tex]
Multiply both sides by m + f
[tex]1500(m+f) = \frac{1560m + 1260f}{m+f} * (m+f)[/tex]
[tex]1500(m+f) = 1560m + 1260f[/tex]
Open brackets
[tex]1500m+1500f- = 1560m + 1260f[/tex]
Collect like terms
[tex]1500f -1260f = 1560m - 1500m[/tex]
[tex]240f = 60m[/tex]
Divide through by 60
[tex]\frac{240f}{60} = \frac{60m}{60}[/tex]
[tex]4f = m[/tex]
Reorder
[tex]m = 4f[/tex]
At this point, the percentage male and female can be calculated;
Male = (Number of male/Total Employees) * 100%
[tex]Male = \frac{m}{m+f} * 100[/tex]%
Substitute 4f for m
[tex]Male = \frac{4f}{4f+f} * 100[/tex]%
[tex]Male = \frac{4f}{5f} * 100[/tex]%
[tex]Male = \frac{4}{5} * 100[/tex]%
[tex]Male = 0.8 * 100[/tex]%
[tex]Male = 80[/tex]%
If percentage of male = 80%
Percentage of Female = 100% - 80%
[tex]Female = 20%[/tex]%
