The marked price of a mobile is 25% above its cost price, When it is sold at a gain of
10%, the profit amounts to Rs 725. Find the marked price of the mobile.
Answer:
The marked price is Rs 823.86
Step-by-step explanation:
Let the cost price be Rs x. The marked price of the mobile is 25% above its cost price. Therefore:
The marked price = x + 25%(x) = 1 + 0.25x = 1.25x
When the mobile phone is sold at a gain of 10%. the profit is Rs 725, to find the cost price we use:
x + 10%(x) = 725
x + 0.1(x) = 725
1.1x = 725
x = 725/1.1 = 659.09
The cost price is Rs 659.09. Therefore the marked price is given as:
Marked price = 1.25x = 1.25(659.09) = 823.86
The marked price is Rs 823.86
What is 105x - 125y + 236z if "x = 10, y = 23, and z = 54" (40 points!) GIVE A GOOD EXPLANATION, NOT JUST AN ANSWER, WHO EVER DOES IT RIGHT FIRST GETS BRAINLIEST.
Answer:
Hey mate, here is your answer. Hope it helps you.
Step-by-step explanation:
105x-125y+236z
Now you need to multiply the values which are given for respective variables.
=105*10-125*23+236*54
=1050-2875+12744
=10919
Hi there friend!
The answer: 10,919
First we need to rewrite the problem.
105(10) - 125(23) + 236(54)
Now we need to multiply everything like so it looks like this:
1050 - 2875 + 12744 which equals:
10,919
Find the value of x to the nearest tenth.
Answer:
Step-by-step explanation:
Using Pythagoreus Theorem
In the smaller rectangle
2²+4² = h²
20 = h²
h = √20
h = 2√5
Therefore two sides of the rectangle will 2√5
No using pythagoreus theorem in the bigger triangle
x² + (2√5)² = 9²
x² = 9² - (2√5)²
x² = 81 - 20
x = √61
x = 7.8102496759
When rounded off to nearest tenth the hundreth digit is in 0-5 range
x = 7.81

There are two types of boxes containing mangoes. Each box of the larger type contains 4 more mangoes than the number of mangoes contained in 8 boxes of the smaller types. Each box has 100 mangoes. Find the number of mangoes contained in the smaller box.
Answer:
12 mangoes
Step-by-step explanation:
Two types of boxes contains mangoes
The larger box contain 4 mangoes than the number of mangoes that is present in 8 smaller box
Each of the box have a total of 100 mangoes
Let y represent the number of mangoes that is present in the smaller box
Therefore, the number of mangoes in the smaller box can be calculated as follows
8y + 4= 100
Collect the like terms
8y= 100-4
8y= 96
Divide both sides by the coefficient of y which is 8
8y/8= 96/8
y= 12
Hence the number of mangoes that is present in the smaller box is 12
The reciprocal of 1 is *
Answer:
[tex]\boxed{1}[/tex]
Step-by-step explanation:
When finding the reciprocal of a value, it flips the denominator with the numerator and vice versa.
The number 1 can be represented as the fraction 1/1 and 1 divided by 1 is still equivalent to 1.
Therefore, the reciprocal of 1 will always be 1.
Mr. A runs 500 meters in 1 minute, Mr. R runs 450 meters in 50 seconds, Mr. M runs 600 meters in 70 seconds and Mr. K runs 400 meters in 45 seconds. Based on these times, which runner would win a 100 meter race?
Step-by-step explanation:
1minute=60seconds
500 meters=60
100 meters=x
cross multiply
500×x=100×60
500x=6000
x=12
Mr. A will use 12seconds
450meters=70
100=a
cross multiply
450×a=100×70
450a=7000
divide both sides by 450
400=45
100=n
cross multiply
400×n=100×45
400n=4500
divide both sides by 400

If (8z − 9)(8z + 9) = az2 − b, what is the value of a?
Explanation:
We use the difference of squares rule to say
(m-n)(m+n) = m^2 - n^2
So in this particular case,
(8z-9)(8z+9) = (8z)^2-(9)^2 = 64z^2 - 81
We can see that the 64 matches with the 'a' of the expression az^2-81, which must mean a = 64
Side note: This means b = 81
Answer:
64

6(2)
12
Hope this helps :)
Answer:
12
Step-by-step explanation:
Replace x by 7 in 6(x-5) to be able to evaluate the expression.
● 6(x-5)
● 6(7-5)
● 6 × 2
● 12
So the expression is equal to 12 when x=7

determine whether or not the function r(x) =x^2-2 is one -to-one
Answer:
The function is not one-to-one
Step-by-step explanation:
This is a quadratic function.
[tex]f(x)=x^2-2[/tex]
A function is one-to-one
[tex]\text{if } f(x_1)=f(x_2) \Leftrightarrow x_1=x_2[/tex]
The function given is not one-to-one because there are values of the input [tex]x[/tex], which leads to the same output.
For example.
[tex]y=f(2)=2^2-2=\boxed{2}[/tex]
[tex]y=f(-2)=(-2)^2-2=\boxed{2}[/tex]

Answer:
Range : { -5,1,7}
Step-by-step explanation:
Take the values in the domain and substitute into the equation
x = -3
y = -2(-3) +1 = 6+1 =7
x = 0
y = -2(0) +1 = 0+1 =1
x = 3
y = -2(3) +1 = -6+1 =-5
The range is the y values
We put then in order from smallest to largest
Range : { -5,1,7}
What are the solutions of x2 + 20 = 12x.
Answer:
x₁ = 2
x₂ = 10
Step-by-step explanation:
x² + 20 = 12x
x² - 12x + 20 = 0
(x-2)(x-10) = 0
then:
x₁ = 2
x₂ = 10
Check:
x₁
2² + 20 = 12*2
3 + 20 = 24
x₂
10² + 20 = 12*10
100 + 20 = 120
Your baseball team has won 6 games and lost 4 games. If the team
does not lose any more games, how many games must the team win
to have a win : loss ratio of 2:1? Explain your answer.
Answer:
two games must be won by the team
Step-by-step explanation:
Let the no. of games played by x, since team
does not lose any more games.
Then total game won = 6+x
total game lost = 4
win: loss = 6+x : 4
given ratio of win and loss = 2:1
6+x : 4 = 2: 1
6+x = 8
=> x = 8-6 = 2
Thus, two games must be won by the team
then total win will be = 6+2 = 8
and loss = 4
ration of win : loss = 8:4 = 2:1
Q: Marci wants to prove that the diagonals of
a rectangle are congruent. Which of these
procedures would be best for Marci to use
to write a correct proof?
a) She should use the fact that the
diagonals of a square are perpendicular
and then use the triangle-angle-sum
theorem.
b) She should use the fact that the
opposite sides of a parallelogram are
congruent and then use the
Pythagorean theorem.
c) She should use the fact that the
opposite angles of a parallelogram are
congruent and then use triangle
similarity relationships.
d) She should use the fact that the
diagonals of a parallelogram bisect the
angles of the parallelogram and then
use triangle congruence relationships.
Answer: Option B
She should use the fact that the
opposite sides of a parallelogram are
congruent and then use the
Pythagorean theorem.
We cannot use the diagonals of square property because this is a rectangle, opposite angles will also not work, and we cannot use the diagonal property because thats what we have to prove.

Answer:
18 + √3
Step-by-step explanation:
The product of a surd and its conjugate gives a rational number. Hence;
(18 - √3) (18 + √3)
=324 + 18√3 - 18√3 - 3
=321
A rational number does not contain any surd, hence the answer.

What is the surface area of the sphere below?
Hey there! I'm happy to help!
To find the surface area of a sphere, here is what you do.
You square the radius.
4²=16
You multiply by 4.
16×4=64
And you multiply by pi!
64×π=64π
Therefore, the surface area of the sphere is A. 64π units². It's that easy!
Now you can find the surface area of a sphere! Have a wonderful day! :D

If the angles a°&b° are complements of each other, then a°+b°= 90° 180° 270° 360°
Answer:
a + b = 90°
Step-by-step explanation:
If sum of two angles are 90°, then the two angles are complementary
Angles that are complements form corners. I've bolded the "co" letters to help remember that complementary angles form a 90 degree corner. Whereas supplementary angles form a straight line (both "supplementary" and "straight" start with "S"). So that's one way to remember the two terms.
Anyways, if a and b are complements of each other, then a+b = 90.
