Answer:
1.
30/100×450
0.3×450
135
450-135=315
So the sale price of a shirt is Nu.315
2.
30/100×450
0.3×450
135
450+135=585
So the selling price of the shirt is Nu.585
Answer:
Q1:315
Q2:585
Step-by-step explanation:
450 -30% (Percentage decrease) =
450 - (30% × 450) =
450 - 30% × 450 =
70 ÷ 100 × 450 =
70 × 450 ÷ 100 =315
Q2: 450 + 30(Percentage increase) =
450 + (30% × 450) =
450 + 30% × 450 =
130 ÷ 100 × 450 =
130 × 450 ÷ 100 =585

Which is the equation in point slope form for the line that passes through (3,7) and is perpendicular to 3x-5y=8?
Answer:
Step-by-step explanation:
eq. of line is 3x-5y=8
5y=3x-8
y=3/5 x-8/5
its slope=3/5
slope of line perpendicular to it=-5/3
eq of line with slope -5/3 and passing through (3,7) is
y-7=-5/3(x-3)
or 3y-21=-5x+15
or 5x+3y=15+21
or 5x+3y=36

Find the equation of the line that contains the given point and is perpendicular to the given line. Write the equation in slope-intercept form, if possible.
(8,1); y=-8x-1
Answer:
y= ⅛x
Step-by-step explanation:
Slope-intercept form
y= mx +c, where m is the gradient and c is the y-intercept.
Let's find the value of m first.
The product if the gradients of 2 perpendicular lines is -1.
Gradient of given line= -8
m(-8)= -1
m= -1 ÷(-8)
m= ⅛
y=⅛x +c
To find the value of c, substitute a coordinate.
When x=8, y=1,
1= ⅛(8) +c
1= 1 +c
c= 1 -1
c= 0
Thus, the equation if the line is y= ⅛x.
Vector performed an experiment at a local farm to determine if the addition of bananas to his biomass cow manure recipes helps produce more or less energy. He collected random samples of manure and bananas from the farm, prepared 15 bottles of each of both mixtures, and placed a balloon on top of each bottle. After two weeks he measured the circumference of each balloon in centimeters; the bigger the balloon grew, the more energy that was produced. The results of the experiment are displayed in the box plots below.
Which description most accurately summarizes the sample results?
Answer:
For his balloon to grow bigger, more manure is needed to enhance more growth energy
The mean of cow manure with mashed bananas is always more than the mean of only cow manure in any country.
Then the correct option is B.
What is Mean?Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.

The mean of cow manure with mashed banana will be
Mean = 22+22+26+29+30+31+36+36+38+39+43+46+46+49+50/15
= 543/15
= 36.2

Answer:
$997
Step-by-step explanation:
Base Salary: $150 (given)
Additional information on everything he sells: 14%
He sells $6050.00 last week, so then his commision would be 14% of the $6050.
x = 150 + ( 0.14 x 6050 )
OR
14/100 x 6050
would equal: $847
Total pay for last week would equal base salary and the additional pay.
$150 + $847
= $997
His total pay for last week would equal $997.

Which of the lines below is a line of symmetry?
A. Neither
B. Red
C. Yellow
D. Both
Answer:
d, both
Step-by-step explanation:
both separe two identical halves :)
Both yellow and red lines are lines of symmetry to the given figure, Option D is correct.
What is Coordinate System?A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.
A line of symmetry is the line that divides a shape or an object into two equal and symmetrical parts.
We know that the diameter of a circle is a line passing through its center. So, the diameter acts as a line of symmetry dividing the circle into two parts with equal area.
In the given figure both the lines represents symmetry as both the lines are dividing the figure to two equal parts.
Hence, both yellow and red lines are lines of symmetry to the given figure, Option D is correct.
