Answer:
X > 21000
Step-by-step explanation:
Given the following :
Payment plans :
PLAN A:
salary = $1000 per month
Commision = 10% of sales
PLAN B:
salary = $1300 per month
Commision = 15% of sales in excess of $9,000
Hence, for plan B; 15% is paid after deducting $9000 from total sales
For what amount of monthly sales is plan B better than plan A if we can assume that Mike's sales are always more than $9,000.00?
That is ;
Plan B > plan A
Let total sales = x
Plan A:
$1,000 + 0.1x
Plan B:
$1,300 + 0.15(x - 9000)
1300 + 0.15(x - 9000) > 1000 + 0.1x
1300 + 0.15x - 1350 > 1000 + 0.1x
0.15x - 50 > 1000 + 0.1x
0.15x - 0.1x > 1000 + 50
0.05x > 1050
x > 1050/0.05
x > 21000

what is slope 1 and 2?
Answer:
Lets calculate the slope of the line 'l'
Slope is rise over run of a line, so we will see how much the y of the line changes by changing x by 1
So, basically we will select a point on the line and see how much the y-value increases for the point rightward to our point
we see that the y increased by 1 and hence, its slope is 1
Now, the slope of line 'k'
again, we will select a point and go one point to the right
here, we see that the y increases by 2
therefore the slope of line 'k' is 2

Find the range of allowable values based on a measure of 130 inches if the values can vary by 1.4%.
Answer:
130 ± 1.82 inches i.e the range of the values is 128.18 inches to 131.82 inches.
Step-by-step explanation:
The range of values required here implies the values fall between the least and maximum values.
Since the values can vary by 1.4%, the range can be determined by:
1.4% of 130 = [tex]\frac{1.4}{100}[/tex] x 130
= 0.014 x 130
= 1.82
The addition or subtraction of 1.82 to/from 130 inches gives the required range.
i.e the range of allowable values = 130 ± 1.82 inches.
Thus,
130 - 1.82 = 128.18 inches
130 + 1.82 = 131.82 inches
The values falls between 128.18 inches to 131.82 inches.
A train can travel at a rate of 85 miles per hour. At this rate, how many hours will it take the train to go 102 miles
Answer:
[tex]Time = 1.2\ hours[/tex]
Step-by-step explanation:
Given
[tex]Speed= 85\ miles/hour[/tex]
Required
Determine the time for 102 miles
In this case, we make use of Speed formula as follows:
[tex]Speed = \frac{Distance}{Time}[/tex]
This gives:
[tex]85 = \frac{102}{Time}[/tex]
Solve for Time
[tex]Time = \frac{102}{85}[/tex]
[tex]Time = 1.2\ hours[/tex]
Hence, the time needed is 1.2 hours
find the percentage decrease if a players batting average dropped from 0.273 to 0.265 in one season.
Answer:
[tex]\huge\boxed{2.93\%}[/tex]
Step-by-step explanation:
Calculate the difference:
[tex]0.273-0.265=0.008[/tex]
Calculate the ratio:
[tex]\dfrac{0.008}{0.273}=\dfrac{0.008\cdot1000}{0.273\cdot1000}=\dfrac{8}{273}[/tex]
Convert to percentage:
[tex]\dfrac{8}{273}=\dfrac{8}{273}\cdot100\%=\dfrac{800}{273}\%\approx2.93\%[/tex]
Explain how an enlargement of reduction in the dimensions of a building would cause a change in the scale factor.
Answer:
The scale factor represents a proportional relationship between the scale drawing and the building’s dimensions. If the dimensions change, then the scale factor must also change to preserve the relationship.
Step-by-step explanation:
Answer:
The scale factor is a proportional relationship. The scale factor represents a proportional relationship between the scale drawing and the building’s dimensions. If the dimensions change, then the scale factor must also change to preserve the relationship. Enlargements have a scale factor greater than 1. Reductions have a scale factor between 0 and 1. The proportion should be preserved.

[tex]= \frac{ 0.17 \times 0.14 }{0.55 \times 0.15 + 0.28 \times 0.12 + 0.17 \times 0.14 } \\\\= \frac{0.0238}{0.0825 + 0.0336 + 0.0238} \\\\= \frac{0.0238}{0.1399} \\\\=0.1701[/tex]
Graph the line with slope -1 passing through the point (2,-4)
Answer:
put a dot on point (2,-4) then go one to the right and one down hope this helps
Step-by-step explanation:
The equation of the line having a slope of -1, and passing through the point (2, -4) is x + y = - 2.
What is the equation of a line?
The equation of a line is the relation between the x-coordinates and y-coordinates of the points on the line, such that all (x, y) points, satisfies this equation.
The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept of the line.
How to solve the question?In the question, we are asked to graph the line with slope -1, and passing through the point (2, -4).
We know that, the slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept of the line.
Substituting m = -1, x = 2, and y = -4, in the equation, we get:
-4 = -1(2) + b,
or, b = -4 + 2 = -2.
Thus, the equation of the line is: y = -1(x) - 2,
or, x + y = -2.
Thus, the equation of the line having a slope of -1, and passing through the point (2, -4) is x + y = - 2.
The graph for the equation is attached.

Answer:
$15.9
Step-by-step explanation:
$397.5 = 25 hour
=> x dollars = 1 hour
=> 397.5 * 1 = 25 * x
=> 397.5 = 25x
=> 397.5/25 = 25x/25
=> 15.9 = x
So, for 1 hour he earns $15.9

3751.25 cm³
Step-by-step explanation:Hi there !
Volume (sphere) formula
V(s) = (4/3) × π × r³
we have two hemisheres
V(h) = (4/3) × π × r³ /2
= (2/3) × π × r³
V₁ = 2/3 ₓ π ₓ (12cm)³
= 2/3 ₓ π ₓ 1728cm³
= 1152π cm³
V₂ = 2/3 ₓ π ₓ (4cm)³
= 2/3 ₓ π ₓ 64cm³
= 128π/3 cm³
V = V₁ + V₂
= 1152π cm³ + 128π/3 cm³
= 3617.28 cm³ + 133.97 cm³
= 3751.25 cm³
