A shopkeeper fixed the marked price of his radio to make a profit of 30 percentage. allowing rs 30 as a discount then the profit is rs 30. find the cost price
Answer:
First Price - 130% of original price
Marked Price(Second Price) - 0.85 of the first price
Second Price: 0.85 x 1.3 x 1 = 1.105
1.105 - 1 = 0.105(10.5%)
In conclusion, the shopkeeper is making a percentage profit of 10.5%.

Jennifer's Custom Kitchen Supplies sells handmade forks and spoons. It costs the store $2 to buy the supplies to make a fork and $1.20 to buy the supplies to make a spoon. The store sells forks for $6 and spoons for $5.50. Last April Jennifer's Custom Kitchen Supplies spent $27.60 on materials for forks and spoons. They sold the finished products for a total of $98. How many forks and how many spoons did they make last April?
Answer:
8 spoons and 9 forks
Step-by-step explanation:
2 F + 1.2S = 27.60
6 F + 5.5S = 98

4] The spinner below is cut unevenly. The probability of spinning a 1 or 4
are equal. The probability of spinning a 3 is 1/2 of spinning a 2. What is the
probability of spinning an odd number if the probability of spinning a 2 is
16%? Type in a numerical value in percent form with the % symbol (no
spaces). For example: 1%*
Answer:
Probability of spinning an odd number is 84%
Step-by-step explanation:
The probability of spinning a 1 or 4 is equal. Let this probability be X
Probability of spinning a 2 is 1/16
Probability of spinning a 3 is 1/2 of the probability of spinning a 2 i.e 8%
Sum of spinning 1,2,3 and 4 is equal to 100%
X + 16% + X + 8% = 100
2X = 100 - 16-8
X = 76%
Probability of spinning an odd number i.e one and 3 is
76% + 8% = 84%

Find the value of F
Answer:
f = 13[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Given that f and e are congruent then e = f
Using Pythagoras' identity in the right triangle
f² + e² = 26² , that is
f² + f² = 676
2f² = 676 ( divide both sides by 2 )
f² = 338 ( take the square root of both sides )
f = [tex]\sqrt{338}[/tex] = [tex]\sqrt{169(2)}[/tex] = 13[tex]\sqrt{2}[/tex] ≈ 18.4 ( to 1 dec. place )
Answer:
f = 25.85751233
Step-by-step explanation:
f^2+E^2=26^2
suppose y varies inversely with x, and y=39 when x=1/3.what is the value of y when x=26
Answer:
y = 1/2
Step-by-step explanation:
Varies inversely
xy = k
------------------------
Find the constant of variation
y = 39 when x = 1/3
k = 1/3 * 39
k = 13
-----------------------
what is the value of y when x=26
26y = 13
y = 13/26
y = 1/2
Answer:
y = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given y varies inversely with x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition y = 39 when x = [tex]\frac{1}{3}[/tex] , then
39 = [tex]\frac{k}{\frac{1}{3} }[/tex] ( multiply both sides by [tex]\frac{1}{3}[/tex] )
[tex]\frac{1}{3}[/tex] × 39 = k
13 = k
y = [tex]\frac{13}{x}[/tex] ← equation of variation
When x = 26 , then
y = [tex]\frac{13}{26}[/tex] = [tex]\frac{1}{2}[/tex]
Find the volume of a rectangular prism with a length of 9 cm, a height of 13 cm, and a width of 7 cm.
923 cm3
819 cm3
910 cm3
950 cm3
Answer:
819 cm³
Step-by-step explanation:
V=L·H·W
V=9·13·7
V=819 cm³
Answer:
819 cubic cm/ cm3
Step-by-step explanation:
The formula to finding the volume of any prism is V=bh.
Going by this formula, we first will solve for the base.
The formula for a rectangular base is B=LxW.
In your question the length is 9 and the width is 7.
So let's plug this in our base formula: 9x7
Now by simplifying by multiplying the two, we will get a product of 63.
So now our expression is 63h
We now must plug in the height.
According to your question, h=13.
So lets plug it all in.
63(13)
Multiply the two and you get 819.
Since we are finding a volume, this can be labeled as cubic cm or cm3 in your terms.

If every 4 cm on a scale drawing is equal to 3 yards in real life, which of the scaled-drawing lengths below would be less than 9 yards in real life? Select all that apply. A) 16 cm B) 6 cm C) 8 cm D) 24 cm
Answer:
B and C
Step-by-step explanation:
Firstly do 16/4 which gives you 4 and then times that by 4 to give you 12 yards. Rinse and repeat this to find out how many yards are in each situation.
What is (f • g) (x) ?
Answer:
=12x-3
Step-by-step explanation:
Stick g(x) in for x in the function of f(x)
f(x) = -4x+5
g(x) = -3x+2
f(g(x)) = -4( -3x+2) +5
= 12x -8+5
=12x-3
When a constant force is applied to an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object
with mass 15 kg, the acceleration of the object is 5 m/s². When the same force acts upon another object, its acceleration is 3 m/s? What is the mass of this
object?
Answer:
The mass of the object will be "25 kg".
Step-by-step explanation:
Given that,
Mass,
m = 15 kg
Acceleration,
a = 5 m/s²
Now,
The force will be:
⇒ [tex]F = ma[/tex]
[tex]=15\times 5[/tex]
[tex]=75 \ N[/tex]
When, acceleration (a) = 3 m/s²
⇒ [tex]F = ma[/tex]
or,
⇒ [tex]m=\frac{F}{a}[/tex]
[tex]=\frac{75}{3}[/tex]
[tex]=25 \ kg[/tex]
Find the volume.

If f(x)= 5x^5+1, then what is the remainder when f(x) is divided by x+1?
Answer:
Remainder = (-4)
Step-by-step explanation:
f(x) = 5[tex]x^{5} + 1[/tex]
x + 1 = 0
x = -1
f(-1) = 5*[tex](-1)^{5} + 1[/tex]
= 5 * (-1) + 1
= -5 +1

What value of b will cause the system to have an infinite number of solutions? y=6x-b -3x+1/2y=-3
Answer:
b = 6
Step-by-step explanation:
solve the second equation for 'y':
-3x + 1/2y = -3
add 3x to each side to get:
1/2y = 3x - 3
multiply all terms by 2 to eliminate the denominator to get:
y = 6x - 6
now compare '6x-6' with '6x-b'
you want both expressions to be equal because then there are an infinite number of solutions:
b = 6
Can someone help me please
Answer:
x = 1
AB = 9
BC = 9
AC = 18
Step-by-step explanation:
Given that B is the midpoint of AC, we can say that
AB = BC
x² + 8x = 4x + 5
subtract (4x+5) from both sides to make the equation equal to 0, enabling us to solve for x
x² + 4x - 5 = 0
Because 5 and -1 add to 4 (the coefficient to x in 4x) and 5 * (-1) = -5 ( the constant), we can factor this out into
(x+5)(x-1) = 0
Therefore, x² + 8x = 4x + 5 can be true at either x=-5. x=1, or both. Plugging these values in the equations to check, starting with x=-5, we get
-5²+8(-5) =4(-5) + 5
-15 = -15
As a line segment cannot have negative length, and x² + 8x = 4x + 5 is negative when x=-5, x=-5 is not a viable solution
Next, for x=1, we get
1²+8(1) = 4(1) + 5
9=9
Therefore, x=1 is the only solution we have.
We have plugged this in for AB and BC, and 1²+8(1) = 4(1) + 5 = x² + 8x = 4x + 5 = 9 for both AB and BC
Next, AC is simply the sum of the two line segments that make them up, AB and BC, so AC = 9 + 9 = 18

If 6 −8p = 38, then p=
Hey there!
6 - 8p = 38
SIMPLIFY EACH SIDES of the EQUATION
-8p + 6 = 38
SUBTRACT 6 to BOTH SIDES
-8p + 6 - 6 = 38 - 8
KEEP: 6 - 6 because that gives you 0
KEEP: 38 - 6 because that helps you solve for your p-value
38 - 6 = 32
NEW EQUATION: -8p = 32
DIVIDE -8 to BOTH SIDES
-8p/-8 = 32/-8
CANCEL out: -8/-8 because that gives you 1
KEEP: 32/-8 because it helps solve for the p-value
NEW and TEMPORARY EQUATION:
p = 32/-8
-4 = 32/-8
32/-2 = -4
Therefore you answer is: p = -4

9514 1404 393
Answer:
13311₅
Step-by-step explanation:
Each column gets the sum mod 5, with a carry to the next column of the quotient of the sum and 5. For example, in the units column, 2+4 = 11₅, so 1 is written in the units column as the sum, and 1 is carried to the 5s column (next one to the left).
Continuing in this fashion gives the sum 13311₅.
__
If you recognize that 3444₅ = 4000₅ -1, you can subtract 1 from 4312₅ and add 4 in the 5³ place (4th column from the right). That gives you ...
4311₅ +4000₅ = 13311₅
