Answer:
60,000
Step-by-step explanation:
Let us represent:
Costs price = x
Selling price = x - 25%x
x - 0.25x
= 0.75x
If it been sold for Rs 21,000 more then the profit would have been
10%. = x + 10% = 1.1x
1.1x =0.75x + 21000
Collect like terms
1.1x - 0.75x = 21000
0.35x =21000
x = 21000/ 0.35
x = 60000
The cost price of the item = 60,000

Find the surface area of the rectangular prism
Answer:
430 cm squared
Step-by-step explanation:
SA= 2(Length x Base, Base x Height, Height x Length)
15cm x 5cm +
15cm x 7xm +
7cm x 15cm =
215cm
215cm x 2 = 430 cm squared.
(it's perimeter of a 3D object so it must be squared, then volume would be cubed)

Write an equation of the line, in point-slope form, that passes through the points (–7, 2) and (3, –2). Use (–7, 2) as the point (x1, y1)
Answer:
first use the equation m = y2 - y1 / x2- x1 to get the slope
m = -2 - 2 = -4
m = 3 + 7 = 10 when there is a negative for x1 it turns positive
the slope is -4/10 or -2/5
now plus the info into the point slope equation
y - y1 = m (x-x1)
this is in point slope form y - 2 = -2/5 (x + 7)
This is how to get it in y-intercept form
y -2 = -2/5x + -2.8
now add -2 on both sides to the -2.8
y = -2/5x (Slope) + -0.8 y- intercept
Hopefully this is right becuase this is just what i learned

The image shows the angles formed by a pair of scissors. When the scissors are closed, m∠1 = 0°. As the scissors are opened, the measures of all four angles change in relation to each other.
Describe how the measures change as m∠1 increases from 0° to 180°.
Angle 3 is a vertical angle of angle 1 and will always be identical to what angle 1 is.
Angle 2 and angle 4 are supplementary angles to angle 1 and will always be the difference between 180 and what angle 1 is.
For example if angle 1 was 45 degrees, angle 3 would also be 45 degrees and angle 2 and angle 4 would be 180-45 = 135 degrees.

Find the mean of the data.
A bar graph, titled “Visits to Your Website”. The vertical axis is labeled “Number of visits”. The horizontal axis is labeled “Day”. For bar 1, the height is 12. For bar 2, the height is 16. For bar 3, the height is 0. For bar 4, the height is 8. For bar 5, the height is 31. For bar 6, the height is 28. For bar 7, the height is 17.
12, 16, 0, 8, 31, 28, 17
12 + 16 + 0 + 8 + 31 + 28 + 17 = 112
112 / 7 = 16

I need help with question 18. The answer is53√3 ft^2. But how do I get there?
Answer:
Hope it helps....
Step-by-step explanation:
Answer:
52√3 ft²
Step-by-step explanation:
sin 60° = (√3) / 2 = h/8
h = 8 x (√3) / 2 = 4√3
cos 60° = 1/2 = a/8
a = 4 b = 15-4 = 11
area = left triangle + right rectangle
area = (4*4√3) / 2 + 11*4√3
= 8√3 + 44√3
= 52√3

Step-by-step explanation:
If CosA= sqrt 3/2, what is TanA?
Answer:
√(3)/3
Step-by-step explanation:
cos(A) = adj./hyp.
adj. = √(3) or √(3)/2
hyp. = 2 or 1
use unit circle:
hyp. = 1
adj. = √(3)/2
use pythagorean theorem c² - b² = a²
1² - (√(3)/2)² = 1 - 0.75 = 0.25
a² = 0.25
a = √(0.25)
a = 0.5
tan(A) = opp./adj.
tan(A) = 0.5/(√(3)/2)
tan(A) = 1/√(3)
rationalize
tan(A) = √(3)/3
Geeta saves 18% of her monthly salary. If she spends Rs.10250 per month, what is her monthly salary? Please explain by step by step procedure.
Answer:
Rs.12500
Step-by-step explanation:
18% = saved
100 - 18 = 82%(used salary)
82% = 10250
100% = ?
100 × 10250 = 1025000
1025000 ÷ 82 = Rs.12500

what integer divided by 6, less eighteen, is negative 22
Answer: -24
Step-by-step explanation:
[tex]\frac{x}{6} -18 = -22[/tex]
[tex]\frac{x}{6} = -22 + 18[/tex]
[tex]\frac{x}{6} = -4[/tex]
[tex]x= -4*6[/tex]
[tex]x= -24[/tex]

A cell phone company expects that every 2 out of 25 cell phones will have some formof defect. At this rate, how many cell phones out of 500 will be expected to have a defect?
Answer: 40 phones
Step-by-step explanation:
The company expects that every 2 out of 25 phones will have some form of defect.
In percentage terms, this is:
= 2 / 25 * 100%
= 8%
If there are 500 phones therefore, the defected phones would still be the same percentage and the actual number would be:
= 8 % * 500
= 40 phones
