A man bought 500 mangoes and found 1/4 of them rotten .If he sold the rest of mangoes at 3.36 each making 12% profit ,what was the cost price of each mango?
Answer:
The cost price of each mango was $3
Step-by-step explanation:
The man bought 500 mangoes, but 1/4 of them were rotten. There were 1/4*500 = 125 rotten mangoes, thus the number of mangoes he sold is
500 - 125 = 375 mangoes
Selling them at $3.36 each, he had revenue of
375*3.36=$1,260
That amount includes the 12% profit, that is, it's 112% of the cost price, thus the cost price of all mangoes is
1,260 / 112 * 100 = $1,125
The price of each mango was $1,125 / 375 = $3
The cost price of each mango was $3
1) Given h(x)=x-5
a) Determine h^2
b)determine h^3
Answer:
A) x^2-10x+25 B)X^3-15x^2+75x-125
Step-by-step explanation:
H^2=(x-5)(x-5)=x^2-10x+25
H^3=(x-5)(x-5)(x-5)=X^3-15x^2+75x-125

Answer:
x=0 is the solution
Step-by-step explanation:
Notice that the graph is that of a parabola with vertex at the point (0, 0).
When we solve for x in the equation:
- x^2 = 0
then we divide by -1 both sides an get: x^2 = 0/(-1) = 0
and finally use the square root property to find the answer and we get:
[tex]x=+/- \sqrt{0} = +/- 0 = 0[/tex]
Since +0 = - 0 (this is the null value), there is only one solution: x = 0.

Container A and container B have leaks. Container A has 800ml of water, and is leaking 6 ml per minute. Container B has1000 ml, and is leaking 10 ml per minute. How many minutes, m, will it take for the two containers to have the same amount of water?
Answer:
50 minutes
Step-by-step explanation:
First set up an inequality to find you answer like
800 - 6x = 1000 - 10x
then subtract 800 from both sides leaving you with
-6x = 200 - 10 x
Then add 10 x to both sides giving you
4x = 200
The simplify from here by dividing 200 by 4
200/4 = 50 giving you your answer

4. A statistician working for the National Basketball Association supplies the television announcers with interesting statistics. At a certain point in the season, he discovered that in 375 games, 300 were won by the team that was winning the game at the end of the third quarter. The margin of error in a 90% confidence interval estimate of the true proportion of games won by the team leading at the end of the third quarter with the plus-4 adjustment applied is (Show work): (5)
Answer: 0.038
Step-by-step explanation:
Given: Total games : n= 375
Number of games won by the team that was winning the game at the end of the third quarter. = 300
The proportion (p) of the team that was winning the game at the end of the third quarter: [tex]p=\dfrac{300}{375}=0.8[/tex]
Critical z-value for 90% confidence: z* = 1.645
Margin of error =[tex]z^*\sqrt{\dfrac{(1-p)p}{n}}[/tex]
The margin of error in a 90% confidence interval estimate of p [tex]=1.645\sqrt{\dfrac{0.2\times0.8}{300}}\\= 1.645\times\sqrt{0.00053333}\\\\=1.645\times0.0231\\\\=0.0379995\approx$$0.038[/tex]
Hence, the required margin of error = 0.038

Which inequality would result in the shaded solution on the unit circle to the right?
The inequality that would result in the shaded solution on the unit circle to the right is [tex]\cos(x)>\sqrt{3}/2[/tex] and this can be determined by using the trigonometric properties.
Given :
The unit circle is given.
The following steps can be used in order to determine the inequality that would result in the shaded solution on the unit circle to the right:
Step 1 - First determine the value of cosine function when the angle is [tex]5\pi/6[/tex]
[tex]\cos\dfrac{5\pi}{6} = -\cos \dfrac{\pi}{6}[/tex]
[tex]\cos\dfrac{5\pi}{6} = -\dfrac{\sqrt{3} }{2}[/tex]
Step 2 - Now, determine the value of the cosine function when the angle is [tex]\pi/6[/tex].
[tex]\cos\dfrac{\pi}{6} = \dfrac{\sqrt{3} }{2}[/tex]
Step 3 - Now, when the value of 'x' increases then the value of the cosine function also increases.
From the above steps, it can be concluded that the cosine function should be greater then [tex]\sqrt{3} /2[/tex]. Therefore, the correct option is A).

the measure of an angle is 126.6 what is the measure of its supplementary angle
Answer:
The answer is 53.4°Step-by-step explanation:
Let the measure of its supplementary angle be x
Since they are supplementary , it means that the sum of their angles add up to 180°.
To find x add up subtract 126.6 from 180
We have
x = 180 - 126.6
We have the final answer as
