the sugar is sold at rupees 5.4 per kg at a loss of 10% at what price relative is sold per kg to earn a profit of 20%
Answer:
the price sold per kg to earn a profit of 20% is 7.2 kg
Step-by-step explanation:
The computation of the price sold per kg to earn a profit of 20% is shown below:
But before that the normal price per kg is
= 5.4 per kg × 100 ÷ 90
= 6 per kg
Now for 20% profit, the price per kg is
= 6 × (1 + 0.20)
= 6 + 1.2
= 7.2 kg
hence, the price sold per kg to earn a profit of 20% is 7.2 kg

Answer:
y=15
(8,15)
Step-by-step explanation:
[tex]2y=30[/tex]
Divide both sides by 2 to isolate y.
[tex]\frac{2y}{2} = \frac{30}{2}\\y=15[/tex]
Because y=15, the solution is (8,15).

13. Which system of inequalities has no solution?
Answer:
Option A
Step-by-step explanation:
We have y < 2x - 4 and y > 2x + 1.
=> 2x - 4 > 2x + 1
=> -4 > 1
Since this inequality is false for all real values of x, there is no solution for the system of inequalities.
Use the distributive property to remove the parentheses

A pool in the shape of a cylinder with a height of 6 m and a base radius of 7 m is drained for repair. If the rate at which the pool is being drained is 3 m3/min, find the rate at which the water level is falling when the water is 4 m deep to the nearest hundredth.
Answer:
The rate at which the water level is falling when the water is 4 meters deep to the nearest hundredth is 0.02 meters per minute.
Step-by-step explanation:
The volume of a cylinder ([tex]V[/tex]), measured in cubic meters, is represented by the following formula:
[tex]V = \pi\cdot r^{2}\cdot h[/tex] (1)
Where:
[tex]r[/tex] - Radius, measured in meters.
[tex]h[/tex] - Height, measured in meters.
Then, we differentiate (1) in time:
[tex]\dot V = 2\pi \cdot r\cdot h \cdot \dot r +\pi \cdot r^{2}\cdot \dot h[/tex] (2)
Where:
[tex]\dot V[/tex] - Rate of change of the volume, measured in cubic meters per minute.
[tex]\dot r[/tex] - Rate of change of the radius, measured in meters per minute.
[tex]\dot h[/tex] - Rate of change of the height, measured in meters per minute.
Then, we clear the rate of change of the height:
[tex]\pi \cdot r^{2}\cdot \dot h = \dot V-2\pi \cdot r\cdot h \cdot \dot r[/tex]
[tex]\dot h = \frac{\dot V - 2\pi \cdot r\cdot h\cdot \dot r}{\pi \cdot r^{2}}[/tex]
[tex]\dot h = \frac{\dot V}{\pi \cdot r^{2}}-\frac{2\cdot h\cdot \dot r}{r}[/tex]
[tex]\dot h = \frac{1}{r}\cdot \left(\frac{\dot V}{\pi \cdot r}-2\cdot h\cdot \dot r \right)[/tex] (3)
If we know that [tex]\dot V = -3\,\frac{m^{3}}{min}[/tex], [tex]r = 7\,m[/tex], [tex]h = 4\,m[/tex] and [tex]\dot r = 0\,\frac{m}{min}[/tex], then the rate of change of the height is:
[tex]\dot h = \left(\frac{1}{7\,m} \right)\cdot \left[\frac{-3\,\frac{m^{3}}{min} }{\pi\cdot (7\,m)-2\cdot (4\,m)\cdot \left(0\,\frac{m}{min} \right)} \right][/tex]
[tex]h = -0.019\,\frac{m}{min}[/tex]
The rate at which the water level is falling when the water is 4 meters deep to the nearest hundredth is 0.02 meters per minute.
answer questions 11 and 12
really urgenttt
Answer:
11.) 135° 12.) 45°
Step-by-step explanation:
11.) When finding one interior angle, you will have to first find the sum of the interior angle using the formula:
Sum of interior angle = ( n - 2 ) 180° where "n" is the number of sides of that shape. So the working will be:
( 8 - 2 ) 180°
= 6 x 180°
Sum of interior angle = 1080°
To find the angle of one interior angle, divide it by the number of sides of that shape.
1080° ÷ 8 = 135°
∴ The measure of one interior angle is 135°
12.) To find the exterior angle, use the formula:
Exterior angle = 360° ÷ n where "n" is the number of sides of that shape. So the working will be:
360° ÷ 8 = 45°
∴ The measure of one exterior angle is 45°
Extra: You can check if the answer is correct by multiplying the answer you got for the exterior angle with the number of sides and that should give you 360°.

Today, Thurber studies math for 15 minutes and he studies science for 75 minutes. From now on, Thurber
plans to study math for 50 minutes per day and to study science for 30 minutes per day. Will Thurber ever
have studied the same total amount of time for both math and science? Explain. Use the drop-down
menus to complete the sentence.
Answer:
Given:
Today, he studies 15 minutes math and 75 minutes science
and from now on, 50 minutes math and 30 minutes science
Step-by-step explanation:
so if he studies for 1 day total time for math and science will be
math=15+50 science=75+30
=65 minutes =105 minutes
2nd day,
math=65+50 science=105+30
=115 minutes =135 minutes
3rd day,
math=115+50 science=135+30
=165 minutes =165 minutes
So, after three days Thurber will have studied the same total amount of time for both math and science and the time is 165 minutes for both.
In this exercise we have to use interpretation skills to calculate the total time that studied the two subjects:
[tex]165 \ both \ subjects[/tex]
Today, he studies 15 minutes math and 75 minutes science and from now on, 50 minutes math and 30 minutes science. So if he studies for 1 day total time for math and science will be:
Math: [tex]15+50 = 65[/tex] Science: [tex]75+30= 105[/tex]
2nd day:
Math: [tex]65+50 = 115[/tex] Science: [tex]105+30 = 135[/tex]
3rd day:
Math: [tex]115+50= 165[/tex] Science: [tex]135+30= 165[/tex]
So, after three days Thurber will have studied the same total amount of time for both math and science and the time is 165 minutes for both.

Find the value of "k", given that one solution of the equation 5x^2-kx+40 is 4/5
Answer:
k = 2
Step-by-step explanation:
Given
5x² - kx + 40
Solution: ⅘
Required
Find k
If the solution is ⅘, then
5x² - kx + 40 = 0 where x = ⅘
Substitute ⅘ for x
5(⅘)² - k(⅘) + 40 = 0
5(16/25) - k(4/5) + 40 = 0
Multiply through by 25
5(16) - 5 * k(4) + 40 = 0
80 - 20k + 40 = 0
Collect like terms
-20k = 0 - 80 + 40
-20k = -40
Divide both sides by-20
k = 2

Answer:
[tex]0.45, 0.54[/tex]
Step-by-step explanation:
Given
[tex]0.54\ and\ 45\%[/tex]
Required
Order from least to greatest
We start by converting 45% to decimal
[tex]45\% = \frac{45}{100}[/tex]
[tex]45\% = 0.45[/tex]
So, the numbers are:
[tex]0.54\ and\ 0.45[/tex]
On a number line:
0.45 comes before 0.54
This implies that:
[tex]0.45 < 0.54[/tex]
And the required order is:

Find the value of f(5) for the function.
f(x)=−6(x+1)
Answer:
f(5) = -36
Step-by-step explanation:
Plug in 5 as x:
f(x) = −6(x + 1)
f(5) = -6(5 + 1)
Simplify:
f(5) = -6(6)
f(5) = -36
So, f(5) = -36
Building A is 879 feet tall and contains 67 stories. Building B contains 108 stories. If the two buildings have the same number of feet per floor, approximate the height of building B.
Answer:
Building B is about 1416.9 feet tall.
Step-by-step explanation:
Set up the following proportion:
[tex]\frac{879}{67}[/tex] = [tex]\frac{x}{108}[/tex]
Cross multiply.
879 x 108 = 94932
67 x x = 67x
67x = 94932
Divide by 67 on both sides.
x = 1416.9

What number gives a result of -4 when 11 is subtracted from the quotient of the number and 5?
Answer:
35
Step-by-step explanation:
Write an algebraic equation to find the answer. Let x equal the unknown number.
We know that 11 must be subtracted from the quotient of the number and five. A quotient is the term used to describe a result from division - so the part "the quotient of the number and five" must be [tex]\frac{x}{5}[/tex]. Also, 11 needs to be subtracted from it - so this gives us [tex]\frac{x}{5} -11[/tex]. Finally, it's given that the expression gives a result of -4. So, the algebraic equation must be [tex]\frac{x}{5} -11 = -4[/tex].
To find the answer, let's isolate x:
[tex]\frac{x}{5} -11 = -4\\\frac{x}{5} = 7\\x = 35[/tex]
Therefore, the number must be 35.
