A lifeguard at a swimming pool gives one-hour swim lessons to children in the morning before the pool is open to the public. She

earns four dollars per class and fifty cents per swimmer. The minimum wage in her state is $7.25. She hopes to earn more than that amount of money during each class. Write an inequality that models the situation and find the minimum number of students she must teach in each class so that her earnings for that hour exceeds the minimum wage in her state.

Hello,

xy=c²==>y=c²/x
==>y'=dy/dx=-c²/x²==>x² dy/dx+c²=0 (there is a mistake)

Select all the equations where n= 6 is a solution.
timurjin [86]

Answer:

4=10-n

3=n/2

8n=48

Step-by-step explanation:

Because for the first one instead of subtracting 10-n you will subtract 10-4, which is 6 so that one and for the second one you would do the inverse of division and multiply 3x2and get 6 and then for the fourth one you will divide 8/48 and get 6

Hoped this helped!!! Have a Great Day!!! Pls give me BRAINLIEST!!

Jude says that the volume of a square pyramid with base edges of 7 in and a height of 7 in is equal to the volume of a cylinder
irakobra [83]

Answer:

Jude is not correct

Step-by-step explanation:

The volume of a square pyramid is given as:

V = a^2\frac{h}{3}

where a = base edge and h = height

Hence, the volume of the square pyramid with base edge of 7 in and height  of 7 in is:

V = 7^2*\frac{7}{3}

V = 114.3 in^3 ≅ 114 in^3

The volume of a cylinder is given as:

V = \pi r^2h

where r = radius and h = height

Hence, the volume of a cylinder with radius of 7 in and height of 7 in is:

V = \pi *7^2*7

V = 1077.57 in^3 ≅ 1078 in^3

Since their volumes are not equal, Jude is not correct.

True or False? A circle could be circumscribed about the quadrilateral below.
SVEN [57.7K]

Answer:

<em>The correct answer is:   False</em>

Step-by-step explanation:

<u>If the sum of the opposite angles in a quadrilateral is 180°</u>, then a circle can be circumscribed about the quadrilateral.

Here,  \angle B+\angle D= 110\°+90\° = 180\°

but,  \angle A+\angle C= 70\°+90\°= 160\°

So, a circle can't be circumscribed about the given quadrilateral.
