Mrs.magar sold 40 kg of fruits at rate of RS 60 per kg and gained Rs 600 . calculate purchasing rate and profit percent.
Answer:
Purchasing rate = ₹45 per kg
Profit percent = 33.33%
Step-by-step explanation:
Selling price of 1 kg fruit = ₹60
Therefore, S. P. of 40 kg fruits = 40*60 = ₹2400
Gain = ₹ 600 (given)
Cost price (C. P.) = S. P. - Gain
= ₹2400 - ₹600
= ₹ 1800
Rate of purchasing
= C. P. /quantity of fruits
= 1800/40
= ₹45 per kg
Profit percent
= (Gain* 100)/C.P.
= (600*100)/1800
= 60000/1800
=33.33%

Find the volume of a pyramid with a square base, where the side length of the base is 17 in 17 in and the height of the pyramid is 9 in 9 in. Round your answer to the nearest tenth of a cubic inch.
Answer:
The volume of the pyramid is 867 inch^3
Step-by-step explanation:
Here in this question, we are interested in calculating the volume of a square based pyramid.
Mathematically, we can use the formula below to calculate the volume V of a square based pyramid.
V = a^2h/3
where a represents the length of the side of the square and h is the height of the pyramid
From the question, the length of the side of the square is 17 in while the height is 9 in
Plugging these values, we have ;
V = (17^2 * 9)/3 = 17^2 * 3 = 867 cubic inch
Write this expression as a complex number in standard form

Recall that:
[tex]\displaystyle \sqrt{-a} = i\sqrt{a}[/tex]
Therefore:
[tex]\displaystyle \begin{aligned} (-3\sqrt{-81})(-5+\sqrt{-9}) + 9i & = (-3i\sqrt{81})(-5+i\sqrt{9})+9i \\ \\ &= -(3i(9))(-5+i(3))+9i \\ \\ & = -27i(-5+3i)+9i \\ \\ & = 135i -81i^2 + 9i \\ \\ & = 144i - 81i^2 \\ \\ & = 81+144i\end{aligned}[/tex]
Note that i² = -1.
In conclusion:
[tex]\displaystyle (-3\sqrt{-81})(-5+\sqrt{-9})+9i = 81 + 144i[/tex]
2y² +4y-48=0
solve the equation
Answer:
y = - 6, y = 4
Step-by-step explanation:
Given
2y² + 4y - 48 = 0 ( divide through by 2 )
y² + 2y - 24 = 0
Consider the factors of the constant term (- 24) which sum to give the coefficient of the y- term (+ 2)
The factors are + 6 and - 4 , since
6 × - 4 = - 24 and 6 - 4 = + 2 , thus
(y + 6)(y - 4) = 0
Equate each factor to zero and solve for y
y + 6 = 0 ⇒ y = - 6
y - 4 = 0 ⇒ y = 4
Answer:
Step-by-step explanation:
2y² + 4y - 48 = 0
2y² + 12y - 8y + (-8)* 6 = 0
2y(y + 6) - 8(y + 6) =0
(y + 6) (2y - 8)= 0
y + 6 = 0 ; 2y- 8 = 0
y = -6 2y = 8
y = 8/2
y = 4
Solution: y = -6 , 4

If the production rate is 975 brownies per hour at a bakery, how many brownies will be produced in an 8 hour shift?
Answer:
[tex]\large \boxed{\mathrm{7800 \ brownies}}[/tex]
Step-by-step explanation:
975 brownies are produced per 1 hour.
To find how many brownies are produced in 8 hours, multiply the brownies amount by the hours.
975 × 8 = 7800
7800 brownies will be produced in an 8 hour shift.
Answer:
the answer is 7800
Step-by-step explanation:
975 brownies are created per 60 minutes.
To discover what number of brownies are created in 8 hours, duplicate the brownies sum continuously.
975 × 8 = 7800
7800 brownies will be created in a 8 hour move.
Bryan completed a 100-meter race in 11.74 seconds. Luis completed the same race in 11.69 seconds. What was the difference between their times, expressed as a fraction of a second?
Answer:
[tex]\frac{1}{20}[/tex] of a second
Step-by-step explanation:
We can convert each time into fractions.
11.74 is the same thing as [tex]11 \frac{74}{100}[/tex]
and 11.69 is the same thing as [tex]11 \frac{69}{100}[/tex].
We know that 11 - 11 = 0, so we can focus on the fractions for now.
Let's subtract [tex]\frac{69}{100}[/tex] from [tex]\frac{74}{100}[/tex].
[tex]\frac{74}{100} - \frac{69}{100} = \frac{5}{100}[/tex].
We can now simplify [tex]\frac{5}{100}[/tex] by dividing both the numerator and denominator by 5.
[tex]\frac{5\div5}{100\div5} = \frac{1}{20}[/tex].

A farmer has 2000 plants. He wants to plant these in such a way that the number of rows and the number of columns remain same. Find the minimum number of plants he needs more for this. 4.
Answer:
500 plantsStep-by-step explanation:
Step one:
given that the number of plants the farmer has is 2000
for him to plant in equal rows and column he needs an amount of plant the is a perfect square.
The closest number to a perfect square is 2500
Step two:
From the above figure which is 2500 plants, the farmer is able to plant 50 rows and 50 columns.
multiplying these values together will amount to 2500
Hence the farmer needs at least 500 plants to achieve this
Answer:
25
Step-by-step explanation:
Number of plants = 2000
He wants to plant such that number of rows and column of plants remain the same, Find the minimum number of plants he needs more for this:
To obtain this,
We take the square root of 2000
Sqrt(2000) = 44.721359
Therefore, the number of columns and rows we need is a natural number whereby the square root of its square is perfect (that is leaves no remainder).
The minimum number will thus be ; the next natural number or integer after 44.721359, whish is 45
Taking the square of 45
45^2 = 2025
The minimum number of plants needed more is :
2025 - 2000 = 25 plants
Find an equation of the line with x-intercept 8 and y-intercept 4
Answer:

4/-8
-1/2
We can use the slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -1/2x + 4
Answer:
Step-by-step explanation:
eq. of line with intercepts a and b is
[tex]\frac{x}{a} +\frac{y}{b} =1\\here ~eq. ~of ~line~ is ~ \frac{x}{8} +\frac{y}{4} =1\\or x+2y=8\\[/tex]
