A butcher purchases 50 chicks at the rate of Ts.60 per chick.10 of them died and he sold remaining chicks at the rate of Rs.80 per chick. Find profit or loss percentage.
Answer: 6.25%
Step-by-step explanation:
50 chicks were purchased at Rs. 60. The total cost of the chicks is:
= 50 * 60
= Rs. 3,000
10 of the chicks died which means the farmer was left with 40 chicks.
These chicks are sold at Rs. 80. Total revenue from the sales are:
= 40 chicks * 80
= Rs. 3,200
The profit is:
= 3,200 - 3,000
= Rs. 200
The percentage is:
= Profit / Revenue
= 200 / 3,200
= 6.25%
What is the radius, Diameter, Area, and Circumference of a 12 feet circle? (No links or fake answers, actually give me a right answer)
Answer:
12ft, 6ft, 36πft², 12πft
Step-by-step explanation:
Diameter: the distance across the circle - so 12ft
Radius: half the diameter = 0.5(12) = 6ft
Area: πr² = π(6)² = 36π ft² (substitute in 22/7, 3.14, or the exact value of π as fit)
Circumference: 2πr = πd = 12πft

Karen is adding a border to a rectangular poster. The border will have a uniform width of X inches and run along all four sides, so Karen uses the functions land wto model the length and width, in inches, of her poster after she adds the border. l(x) = 2x+ 18 W(x) = 2x+ 24 Which function correctly represents the total area, in square inches, of Karen's poster, when a border x inches wide is included in the area?
A. A(X) = 4x + 432
B. A(X) = 4x2 + +42x + 432
C. A(x) = 4x2 + +84x + 432
D. A(x) = 4x + 432
Answer:
B. A(x) = 4x² + 42x + 432Step-by-step explanation:
The area is the product of the width and the length:
A(x) = (2x + 18)(2x + 24) = 4x² + 42x + 432Correct choice is B
The fourth term of an exponential sequence is 108 and the ratio is 3 . Calculate the value of the eighth term of the sequence, calculate the sum of the first five terms of the sequence.
Answer:
8th term = 8748 , Sum of 5 terms = 484
Step-by-step explanation:
Formula for nth term in an exponential sequence = a r^ (n-1)
Here : n = 4 , ratio r = 3 ; And nth ie 4th number = 108
So, a r^ (n-1) = nth item implies that → a 3 ^ (4-1) = 108
a 3^3 = 108 → 27 a = 108 → a = 108 / 27 → a = 4
8th term = a r^ (n-1) , at n = 8. So, = 4 3^(8-1) = 4 3^7 = 4 x 2187 = 8748
Sum of n terms = a [(r^n) -1 ] / [r - 1] → Sum 5 terms = 4 [ (3^5)- 1] / [3 - 1]
= 4 [ (243) - 1] / 2 ] = 2 x 242 = 484
The area of a regular polygon is 100.8cm2. The perimeter is 56cm, what is the length of the apothem
Answer:
3.6 cm
Step-by-step explanation:
Note that:
Area = 1/2 x perimeter x apothem.
To find the Apothem, the formula =
Area ÷ (1/2 × Perimeter)
Area = 100.8cm²
Perimeter = 56 cm
Hence,
Apothem =
100.8 cm² ÷ (1/2 × 56 cm)
= 100.8cm² ÷ 28cm
= 3.6 cm
Therefore, the Length of the apothem is 3.6 cm

if we buy 20 pickles what is the experimental probability of winning 5 or more tickets
Answer:
[tex]Pr = 0.66[/tex]
Step-by-step explanation:
Given
See attachment for complete question
Required
[tex]P(x \ge 5)[/tex]
From the attachment, we have:
[tex]S = 2 + 8 + 4+20+21+19+17+5+2+2[/tex]
[tex]S =100[/tex] ---- the sample size
Next, we list out all outcomes more than or equal to 5.
i.e.
[tex]x \ge 5[/tex]
5 is represented with the vertical blue rectangle (with frequency 21).
So, the other elements are to the right of frequency 21.
So, we have:
[tex]x \ge 5 = 21+19+17+5+2+2[/tex]
[tex]x \ge 5 = 66[/tex]
The probability is then calculated as:
[tex]Pr = \frac{x \ge 5}{S}[/tex]
This gives
[tex]Pr = \frac{66}{100}[/tex]
[tex]Pr = 0.66[/tex]

If we subtract 7 from both sides, we get -2 on the right. This is not possible, since absolute values are always 0 or greater.
Solve: 2x-4 = -(x-6)/2
Answer:
x = 14/5
Step-by-step explanation:
2x-4= -x-6/2
multiply by 2 on both sides to get rid of the fraction
4x-8= -x-6
add both sides by 8 and both sides by x to get the constants on the right and the variables on the left
4x+x=6+8
combine like terms/simplify
5x=14
divide both sides by 5 to isolate the x
x=14/5

On a standardized exam, the scores are normally distributed with a mean of 250 and
a standard deviation of 50. Find the 2-score of a person who scored 375 on the exam.
Answer:
the z-score is within 3
Step-by-step explanation:
first you got to take the standard deviation and add it to the mean since 375 is greater than 250. so the equastion would be
250+50=300+50=350+50=40
so the z-score for the value of 375 is within 3
Answer: 2
Step-by-step explanation:
z=\frac{x-\mu}{\sigma}
z=

x−μ
z-score formula
z=\frac{300-250}{25}
z=
