find the selling price if the cost price is rupees 600 and profit is 13%
Answer:
=2277 Ans.
Step-by-step explanation:
Find the selling price
(a) Cost =600
Profit=13%
Selling price =Cost + profit
=600+
100
600×13
=600+78
=678 Ans.
(b) Cost=2475, loss=8%
Selling price = Cost+ profit/loss
=2475+(−

=2475−198
=2277 Ans.
Which expression is NOT equivalent to the expression 8m + 12?
A - 1/2 (16m + 24)
B - 4 (2m + 3)
C - 2 (4m + 6)
D - 8 (m +12)
9514 1404 393
Answer:
D. 8 (m +12)
Step-by-step explanation:
One cannot factor the coefficient from the first term and apply that to both terms. The result is NOT equivalent.
8m +12 ≠ 8(m +12) = 8m +96
Randy wants to install a patio, which will be filled with concrete. The dimensions of the patio are 14 m long, 8 m wide, and 1 m deep. Determine the cost of the
concrete to be used while installing the patio if the concrete is available to Randy at the rate of $5 per cubic meter.
The cost of the concrete for installing the patio will be,
Answer:
Total cost of patio = $560
Step-by-step explanation:
Given:
Length of patio = 14 m
Width of patio = 8 m
Height of patio = 1 m
Cost of 1 m³ concrete = $5
Find:
Total cost of patio
Computation:
Volume of patio = l x b x h
Volume of patio = 14 x 8 x 1
Volume of patio = 112 m³
Total cost of patio = Volume of patio x $5
Total cost of patio = 112 x $5
Total cost of patio = $560

The figure is a kite. The m < 4 = 72 and m < 3 = 18. Find m < 2.
The sum of the angles for a 4 sides figure must add up to 360.
Angle 1 and angle 2 are between similar sides so the 2 angles are identical.
Subtract the known angles from 360:
360 - 72 - 18 = 270
Divide that by 2:
270*2 = 135
Angle 2 = 135 degrees.

Step-by-step explanation:
X is directly proportional to y.work out the missing values,p and q, in the table
Answer:
p = 21, and q = 30
Step-by-step explanation:
If x is directly proportional to y, then we know:
y = 35x / 60
We can factor 5 out of that, giving us:
y = 7x / 12
We can also find the inverse of that relationship:
y = 7x / 12
12y = 7x
x = 12y / 7
So in the second row, where x = 36:
y = 7 × 36 / 12
y = 7 × 3
y = 21
And in the third row where y = 17.5:
x = 12 × 17.5 / 7
x = 210 / 7
x = 30
So p = 21, and q = 30

b. 362,880
Step-by-step explanation:

A chef is choosing from 13 different entrees for an important banquet, 3 of which contain spinach. The guests will have a choice of 4 entrees. The chef has decided to choose the 4 at random. Write your answers as a decimals rounded to the nearest thousandth. What is the probability that none of the chosen entrees contain spinach
Answer:
0.294 = 29.4% probability that none of the chosen entrees contain spinach.
Step-by-step explanation:
The choices of entrees are chosen without replacement, which means that the hypergeomtric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
13 different entrees for an important banquet
This means that [tex]N = 13[/tex]
3 of which contain spinach.
This means that [tex]k = 3[/tex]
The guests will have a choice of 4 entrees.
This means that [tex]n = 4[/tex]
What is the probability that none of the chosen entrees contain spinach?
This is P(X = 0). So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 0) = h(0,13,4,3) = \frac{C_{3,0}*C_{10,4}}{C_{13,4}} = 0.294[/tex]
0.294 = 29.4% probability that none of the chosen entrees contain spinach.

A. Y = 1/3(3)^x
B. Y= 3(1/3)^x
C. Y= (1/2)^x +2
D. Y=(2)^x - 1
Answer:
B
Step-by-step explanation:
Look at the graph, it passes to (0,3), so you need to replace that coordinate into A,B,C,D. Then you can see, there is only B and C satisfies.
[tex]Y=3(\frac{1}{3} )^{0}=3.1=3.[/tex]
and
[tex]Y=(\frac{1}{2} )^{0}+2=1+2=3[/tex]
Next step, you can see when x approach to infinite then Y approach to 0.
Hence, we will take limit of B and C, if limit B or C equals to 0 then we will choose.
[tex]\lim_{x \to \infty} {3(\frac{1}{3})^x=3. \lim_{x \to \infty} {(\frac{1}{3})^x=3.0=0[/tex]
and
[tex]\lim_{x \to \infty} {[(\frac{1}{2})^x+2]}= \lim_{x \to \infty} {(\frac{1}{2})^x}+ \lim_{x \to \infty} {2}=0+2=2[/tex]
We can see that only B is satisfied.
