Can someone help me solve this? ^^

Answer:

let cp of 17 water bottle is x

cp of 1 water bottle = x/17

from the question

sp of 16 water bottles = x

sp of 1 water bottle = x/16

profit = sp -cp

        = x/16 - x/17

      =  x/272

profit % = profit /cp * 100%

            = (x/272)/ (x/17) * 100%

= 6.25%

Answer:

500

Step-by-step explanation:

50x10 = 500

50 feet per second so we multiply 50 (the speed per second) by 10 (the time given). You can also use a formula like this:

S x T

S= Speed

T= Time

Answer:

If Z is a complex number:

Z = a + b*i

where a and b are real numbers, and i is an imaginary number.

Then "a" is the real part.

"b*i" is the imaginary part.

The conjugate of Z is:

Zc = a - b*i

So the sign of the imaginary part changes.

Then:

Sum:

Z + Zc = (a + bi) + (a - bi) = 2*a + 0 = 2*a

and remember that a is a real number, then 2*a is also a real numer.

The correct answer is "A real number".

Difference:

Z - Zc = (a + bi) - (a - bi) = 2b*i

and this is a pure imaginary number, so here the correct answer is: "a pure imaginary number"

Answer: a pure imaginary number

explanation:

The sum of a complex number and its conjugate will always be two times the real part of that complex number.

Z=a+b*i

where a and b are real numbers, and i is an nonexistent number.

Then a is the real part.

"b*i" is the imaginary part.

The connection of Z is:

Zc = a - b*i

So the sign of the imaginary part changes.

Sum:

Z + Zc = (a + bi) + (a - bi) = 2*a + 0 = 2*a

and remember that a is a real number, then 2*a is also a real number.

The correct answer is "A real number".

Difference:

Z - Zc = (a + bi) - (a - bi) = 2b*i

Answer:

87, median is the middle value

Step-by-step explanation:

put them in order from least to greatest

56, 72, 87, 89, 93

87 is your median

Answer:

The median of her scores is 87

Step-by-step explanation:

What is median?

The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers) is called a median.

Arranging the data in ascending order.

56,72,87,89,93.

n=5

Median =[(n+1)/2]th observation.

            =[(5+1)/2]th observation

           =3rd observation

          = 87

Hence, the answer is Option (B) 87

...............

Answer:

-20

Step-by-step explanation:

a2 + ( b-c)

rewrite the equation

2 * a + ( b - c )

a = -8

b = 17

c = 21

substitute in the given values

(-8) 2 + ( (17) - (21) )

simplify and solve

-16 + ( 17-21)

= -16 +  (-4)

= -16 -4

-27 is moved to the right side making it +27 and cancelling out with the -27.

Answer:

7-56n

Step-by-step explanation:

By using the distributive property you multiply the 7 to the 1 which equals 7. Then you distribute the 7 to the -8n which gives you -56n becaus emultiplying a negative and a possitive gives you a negative.

The required solution is -56n+7.

It is required to find the solution.

A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Given:

Rearrange terms

7(1 - 8n)

=7(-8n+1)

Then distribute by multiplying 7 we get,

-56n+7

Therefore, the required solution is -56n+7.

Answer: p-q

Step-by-step explanation:

Answer: P-Q is correct

Step-by-step explanation:

Answer:

p = 6, q = - 1

Step-by-step explanation:

Factor the left side and compare to right side

y² + 5y - 6

Consider the factors of the constant term (- 6) which sum to give the coefficient of the y- term (+ 5)

The factors are + 6 and - 1, since

6 × - 1 = - 6 and 6 - 1 = + 5, thus

y² + 5y - 6 = (y + 6)(y - 1)

Compare with (y + p)(y + q) , then

p = 6 and q = - 1

Answer:

yes
