Step-by-step explanation:
C.P. = Rs400, Loss = 12% , Find S.P
Answer:
Step-by-step explanation:
CP= Rs 400
loss%=12%
let sp be x
SP=CP-loss%*CP
x=400-12/100*400
x=40000-4800/100
x=35200/100
x=352
therefore sp =Rs 352
Answer:
S.P. = ₹352
Step-by-step explanation:
UNITARY METHOD:
If C.P. = ₹100
Then SP = ₹(100-12) = ₹88
If C.P. = ₹1
S.P. = ₹(88/100)
Then, as given: C.P. = Rs 400
S.P. = ₹( 88/100)*400
= ₹352
Therefore, S.P. = ₹352

Answer:
1 1/2
Step-by-step explanation:
2 2/3 - 1 1/6 = ?
The LCD here is 6. Convert 2 2/3 so that the denominator is 6:
2 2/3 = 2 4/6
Then subtract 1 1/6 from 2 4/6: We get 1 3/6, or 1 1/2
What does difference of squares mean? How can you recognize it when looking at an expression?
Find the value of x
a) 57
b) 60
c) 69
d) 63
Answer:
b
Step-by-step explanation:
The tangent- secant angle 55° is equal to half the difference of its intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (170 - x) = 55 ( multiply both sides by 2 to clear the fraction )
170 - x = 110 ( subtract 170 from both sides )
- x = - 60 ( multiply both sides by - 1 )
x = 60 → b

He can tell there is 10% atleast for hot and 0% for a large
The probability that a customer ordered a hot drink given that he or she ordered a large is 22%
What is probability?Probability denotes the possibility of the outcome of any random event.
Given that a table of the first 100 customers' orders at a coffee shop.
We need to find the probability that a customer ordered a hot drink given that he or she ordered a large,
= 22 / 100
= 22%
Hence, the probability that a customer ordered a hot drink given that he or she ordered a large is 22%

Diego is designing an exercise room. How many
square feet of rubber flooring will he need to cover the floor?
The product is sold in whole square yards. How many square
yards should Diego buy? Explain.
The required figure is attached below :
Answer:
138 feet²
Step-by-step explanation:
To obtain the amout of rubber flooring needed to cover the floor, we take the area of the figure below :
A breakdown of the first gure is also attached below :
Area of rectangle (1) = Length * width = 15 feets * 6 feets = 90 ft²
Area of rectangle (2) = length * width = 6 feets * 8 feets = 48 feets
Area 1 + Area 2
90 feet² + 48 feet² = 138 feet²
Aldo needs 46 cookies for a party.
The cookies he wants come in packs of 8.
How many packs should he buy?
Answer:
6 Packs
Step-by-step explanation:
Since he needs 46 cookies, he will have to buy 46/8 which is 5.75 packs. But since the packs are sold in whole, not fractions, he buys a ceil approximation of the packs which is 6, because if he buys 5, it will not be enough.
∠A and \angle B∠B are complementary angles. If m\angle A=(2x-4) ∘ and m\angle B=(5x+17) ∘ , then find the measure of \angle A∠A.
Answer: 18°
Step-by-step explanation:
Complementary angles are the angles that when we add them together, the value will equal 90°.
In this question, we've to add both angles and equate them to 90°. This will be:
(2x - 4) + (5x + 17) = 90
2x - 4 + 5x + 17 = 90
Collect like terms
2x + 5x = 90 + 4 - 17
7x = 77
x = 77/7
x = 11
Angle A will be:
= (2x-4)
= 2(11) - 4
= 22 - 4
= 18°

Find the mean of the data set {4.5,5, 3.5, 2, 2.5}.
So what is the answer ;, I nordeste im
Answer:
Mean = 3.5
Step-by-step explanation:
The given data is :
4.5,5, 3.5, 2, 2.5
We need to find the mean of the given data.
We know that,
Mean = sum of observations/total no. of observations
Here,
Total no. of observations = 5
Sum of observations = 4.5 + 5+ 3.5+ 2+ 2.5 = 17.5
Mean,
[tex]m=\dfrac{17.5}{5}\\\\m=3.5[/tex]
Hence, the mean of the data set is equal to 3.5.

Supongamos que un restaurante ofrece 5 entradas, 4 platos principales y 3 postres. ¿De
cuántas formas un cliente puede ordenar una comida?
Answer:
El cliente puede ordenar una comida en 60 formas distintas.
Step-by-step explanation:
El cliente escoge una entrada de las cinco opciones disponibles, luego un plato principal de cuatro opciones disponibles y un postre de tres opciones disponibles. Es costumbre consumir primero una entrada, después un plato principal y finalmente, un postre.
Estadísticamente hablando, se debe considerar un producto de tres combinaciones, puesto que el orden no importa a la hora de pedir, como sigue:
[tex]n = _{5}C_{1}\times _{4}C_{1}\times _{3}C_{1}[/tex] (1)
Donde:
[tex]n[/tex] - Total de combinaciones al ordenar una comida (entrada, plato principal, postre)
[tex]_{5}C_{1}[/tex] - Combinaciones posibles para pedir una entrada.
[tex]_{4}C_{1}[/tex] - Combinaciones posibles para pedir un plato principal.
[tex]_{3}C_{1}[/tex] - Combinaciones posibles para pedir un postre.
Ahora, desarrollamos la operación:
[tex]n = \frac{5!}{(5-1)!}\times \frac{4!}{(4-1)!} \times \frac{3!}{(3-1)!}[/tex]
[tex]n = 5\times 4\times 3[/tex]

. A bridge over a river is built in the shape of a parabolic arch. The bridge has a span of 100 feet. The height of the arch is 10 feet at a point 40 feet from the center. Find the height of the arch at its center.
Answer:
The height of the arch at its center is 250/9 or about 27.78 feet.
Step-by-step explanation:
We can write an equation to model the parabolic arch.
Let the left-most point of the arch be the origin (0, 0).
Since the bridge has a span of 100 feet, the right-most point must be (0, 100).
We can use the factored form of a quadratic:
[tex]y=a(x-p)(x-q)[/tex]
Where p and q are the x-intercepts.
Our x-intercepts are x = 0 and x = 100. Hence:
[tex]y=ax(x-100)[/tex]
At a point 40 feet from the center, the height of the arch is 10 feet.
The center is x = 50. So, a point 40 feet from the center can be either x = 10 or x = 90.
So, for instance, when x = 10, y = 10. Substitute and solve for a:
[tex]10=10a(10-100)[/tex]
So:
[tex]\displaystyle a=-\frac{1}{90}[/tex]
The same value will result if we let x = 90 and y = 10.
Hence, our equation is:
[tex]\displaystyle y=-\frac{1}{90}x(x-100)[/tex]
The height of the arch at its center will be when x = 50. Hence:
[tex]y(50)=\displaystyle -\frac{1}{90}(50)((50)-100)=\frac{250}{9}\approx 27.78\text{ feet}[/tex]

A classroom has a length of 20ft. And a width of 30ft. The flooring is to be replaced by tiles. If each tile has a length of 24 in and a width of 36 in, how many tiles are needed to cover the classroom?
Answer:
100
Step-by-step explanation:
first we need to turn the feet into inches
20x12=240
30x12=360
now to get the area of the floor we need to do 360x240=
86,400
now the area of each tile is 24x36=864
now to find out how many tiles fit on the floor we need to do 86,400 divided by 864 which = 100

Tell whether the function table represents a linear or exponential relationship.
Answer: Linear
Step-by-step explanation: When determining whether the function table represents a linear or exponential relationship, we are checking to see if the rate of change is constant or increasing. If we look at the table, when x increases by 1, y increases by 3. This means that on that interval, the average rate of change is 3/1 = 3. When we increase x by 1 again, we see that y increases by 3 again. This means that the rate of change is constant for the function, so it must be linear.

[tex]\dfrac{2.1\times 10^6}{7\times 10^3}=\dfrac{21\times 10^5}{7\times 10^3}[/tex]
[tex]\dfrac{2.1\times 10^6}{7\times 10^3}=\dfrac{21}{7}\times \dfrac{10^5}{10^3}[/tex]
[tex]\dfrac{2.1\times 10^6}{7\times 10^3}=3\times 10^{5-3}[/tex] [tex][\because \dfrac{a^m}{a^n}=a^{m-n}][/tex]

Jackson is building a bookshelf and has a piece of wood that is 5/8 long. He needs to cut pieces that are 1/16 foot long. How many pieces can Jackson cut?
Answer:
6 is the Answer.Step-by-step explanation:
A fraction consists of two parts the top number and the bottom one.
Think of the top number as the count and the bottom as the size indicator. So you have:
countsize indicator −−−−−−−−−−→proper names numeratordenominator
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Consider the action example of dividing 3 into 6.
We can do this division directly because their size indicators are the same. That is, we have: 61÷31. People do not normally write it this way but it is correct.
To directly divide the counts the size indicator must be the same
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So we need to see how many of 18 will fit into 34
We can not do this directly in one operation as the size indicators are not the same.
Lets make the size indicators (denominators) the same
Multiply by 1 and you do not change the value but
1 comes in many forms.
[34×1]÷18 → [34×22]÷18
[3×24×2]÷18 → 68÷18
Now that the size indicators (denominators) are the same we can just divide the counts (numerators)
countsize indicator→[68÷18]=6÷1=6
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I could explain more showing the connection between this and the shortcut method but what I have shown you will do for now.
