12. An item was sold at a loss of 20%. Had it been sold for Rs. 50
more then, the profit would have been 5%. What is the cost
price of the item?
Given:
An item was sold at a loss of 20%.
If the item is sol for Rs. 50 more then, the profit would have been 5%.
To find:
The cost price of the item.
Solution:
Let x be the cost price of the item.
The item was sold at a loss of 20%. Then selling selling price is:
[tex]S.P.=x-\dfrac{20}{100}x[/tex]
[tex]S.P.=x-0.2x[/tex]
[tex]S.P.=0.8x[/tex]
If a the item is sold for 5% profit, then the selling price is:
[tex]S.P.=x+\dfrac{5}{100}x[/tex]
[tex]S.P.=x+0.05x[/tex]
[tex]S.P.=1.05x[/tex]
It is given that, if the item is sol for Rs. 50 more then, the profit would have been 5%. So,
[tex]0.8x+50=1.05x[/tex]
[tex]50=1.05x-0.8x[/tex]
[tex]50=0.25x[/tex]
Divide both sides by 0.25.
[tex]\dfrac{50}{0.25}=x[/tex]
[tex]200=x[/tex]
Therefore, the cost price of the item is Rs. 200.
The Malcolms are taking a trip. Midville is 214 miles
from their home. Walesburg is 3 times as far.
How far is Walesburg from their home?
Answer:
642 miles
Step-by-step explanation:
Distance of Midville from their home = 214 miles
Walesburg is 3 times as far.
How far is Walesburg from their home?
Distance of Walesburg from their home = 3 × Distance of Midville from their home
= 3 × 214 miles
= 642 miles
Distance of Walesburg from their home = 642 miles

Roció hará un circulo con un diámetro de 22.8 cm cuánto medirá un radio
Answer:
r = 11.4 cm
Step-by-step explanation:
The question says that, "Spray will make a circle with a diameter of 22.8 cm how long a radius will measure."
Given that,
The diameter of the circle, d = 22.8 cm
We know that the relation between the diameter and the circle is given by :
d = 2r
Where
r is the radius of the circle
r = d/2
r = 22.8/2
r = 11.4 cm
So, the radius of the circle is equal to 11.4 cm.
What is the measure of angle B
Answer:
Step-by-step explanation:
angle C + Angle B= Angle A(sum of two interior oppposite angles are equal to the exterior angle formed)
61+B=143
B=143-61
B=82 degree
We know that,
→ C = 61°
[A = B + C]
→ 143° = B + 61°
→ B = 143° - 61°
→ B = 82°
[180° = A + B + C]
→ 180° = A + (82° + 61°)
→ A = 180° - 143°
→ A = 37°
Jesse needs 10 1/4 feet of chain to complete an outdoor project. He has two small pieces each measuring 2 1/8 feet and a third piece measuring 3 3/4 feet. How many feet of chain does Jesse need to purchase?
Answer:
= 2 1/4 feet
Step-by-step explanation:
Length of chain Jesse needs = 10 1/4 feet
Length of chain Jesse has:
Two small pieces each measuring 2 1/8 feet
= 2 × 2 1/8 feet
= 2 × 17/8
= 34/8 feet
Third piece measuring 3 3/4 feet
Total Length of chain Jesse has = 34/8 feet + 3 3/4 feet
= 34/8 + 15/4
= 34+30/8
= 64/8
= 8 feet
Total Length of chain Jesse has = 8 feet
Length of chain Jesse needs to purchase = Length of chain Jesse needs - Total Length of chain Jesse has
= 10 1/4 feet - 8 feet
= 2 1/4 feet
Length of chain Jesse needs to purchase = 2 1/4 feet

What is the area of 9yd and 5yd and how’d you get it
9514 1404 393
Answer:
45 yd²
Step-by-step explanation:
The area of a rectangle is the product of its length and width. If your given measures are the length and with of a rectangle, the area is found by multiplying them.
A = LW
A = (9 yd)(5 yd) = 9·5 yd·yd = 45 yd²
The area of a 9 yd by 5 yd rectangle is 45 square yards.
A is the point (-5, 2)
B is the point (7,-2)
C is the point (-2, 5)
a) Find the gradient of a line perpendicular to line AB.
Step-by-step explanation:
the gradient for the line perpendicular to AB is 3The slope of the line that is perpendicular to the line of AB is: 3.
What is the Slope of Perpendicular Lines?If two lines are perpendicular to each other, their slopes will be the negative reciprocal of each other. i.e., if the slope of one is 3, the slope of the other would be -1/3.
Slope = change in y / change in x
Slope of AB = (-2 - 2) / (7 -(-5))
Slope of AB = -4/12
Slope of AB = -1/3
Negative reciprocal of -1/3 would be 3.
Therefore, the slope of the line that is perpendicular to the line of AB is: 3.

A car tire with a diameter of 1.6 ft rotates 275 degrees . How far does a point on the circumference of the tire travel
Answer:
A point on the circumference of the tire will travel 7.68 ft.
Step-by-step explanation:
Given;
radius of the car tire, r = 1.6 ft
angular distance or rotation = 275⁰
A complete rotation of the tire = 360⁰
the distance a point on the circumference will travel = 2πr
If 360⁰ = 2πr
then 275⁰ = ?
[tex]= \frac{275 \ \times \ 2\pi r}{360} = \frac{275 \ \times \ 2\pi \times 1.6ft}{360} = 7.68 \ ft[/tex]
Therefore, a point on the circumference of the tire will travel 7.68 ft.

Sam and Dean are brothers. Their ages now add up to the age of their sister. In ten years, Dean's age will be the sum of their ages today. How old are each of them?
Answer:
Sam is yeas old, and Dean is (x - 10) year's old, where 'x' is the age of their sister
Step-by-step explanation:
The relationship between the ages of the brothers are;
Sam's age + Dean's age = Their sister's age
Dean's age + 10 = Dean's age + Sam's age
Therefore, we have;
Sam's age = Dean's age + 10 - Dean's age = 10
Sam's age = 10 years
Let 'x' represent their sisters age, we get;
Sam's age + Dean's age = x
10 + Dean's age = x
Dean's age (in variable form) = x - 10
How do I find the height of a pentagonal prism with just an apothem of 11cm and a side length of 9.6cm
Answer:

Given
[tex]l = 9.6cm[/tex] --- side length
[tex]a = 11cm[/tex] --- apothem
[tex]n = 5[/tex]
Required
The height of the prism
The apothem of a prism is:

Write the equation of the line that has a slope of -4 and passes through the point (-2,-5).
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4 , then
y = - 4x + c ← is the partial equation
To find c substitute (- 2, - 5) into the partial equation
- 5 = 8 + c ⇒ c = - 5 - 8 = - 13
y = - 4x - 13 → B

A. 90
B. 80
C. 60
D. 45
Answer:
A 90
Step-by-step explanation:
multiple ways to prove this.
e.g. since the angle between the two lines from the center of the circle to the 2 tangent touching points is 90 degrees (that is the meaning of these 90 degrees here as the angle of the circle segment defined by the 2 tangent touching points and the circle center), the tangents have the same "behavior" as tan and cot = the tangents at the norm circle at 0 and 90 degrees. they hit each other outside of the circle again at 90 degrees.
another way
imagine the two right triangles of the tangents crossing point to the circle center and the tangent/circle touching points.
the Hypotenuse of each triangle is cutting the 90 degree angle of the circle segment exactly in half (due to the symmetry principle). so the angle between radius side and Hypotenuse is 90/2 = 45 degrees.
that means also the angle of such a right triangle at the tangent crossing point is 45 degrees (as the sum of all angles in a triangle must be 180, we have the remainder of 180 - 90 - 45 = 45 degrees).
the angles of both right triangles at that point are the same, and so we can add 45+45 = 90 degrees for the total angle at the tangent crossing point.
Which r-value represents the most moderate correlation?
–0.92
–0.18
0.56
0.83
Answer:
0.56
Step-by-step explanation:
The r-value that represents the most moderate correlation is 0.56
How to determine the moderate correlation value?Correlation is represented with r.
And the range of values of r is:
-1 ≤ r ≤ 1
This means that r can take any value from -1 to 1
-1 and 1 are considered strong correlation
While values closer to 0.5 or - 0.5 are moderate
From the list of options,
0.56 is closer to 0.5 than others
Hence, the r-value that represents the most moderate correlation is 0.56
