makvit [3.9K]

Answer:

The new store will have a profit of $5400 after its fifth month.

(R-C)(x) = (x²+5x+14)-(x²-4x+5) = x²-x²+5x--4x+14-5 = 5x+4x+14-5=9x+9

(Use 5 for x)

(R-C)(5) = 9(5) + 9 = 45+9 = 54

Which equation can be used to find the surface area of the cylinder?

miss Akunina [59]

Answer:

The fourth one

Step-by-step explanation:

Surface area of a cylinder: $SA=2\pi rh+2\pi r^2$

where r = radius and h = height

We have a given height of 14cm and a given diameter of 6cm

We need the radius, not the diameter

To convert diameter to radius we simply divide by 2

6 / 2 = 3

so R = 3

We now plug in the given values into the formula

$SA=2\pi (3)(14)+2\pi (3)^2$

This equation matches with answer choice D

Paladinen [302]

Answer:

Ann sold 124 bottles of drinks in the morning

Step-by-step explanation:

Let

x ---> bottles sold in the afternoon

y ---> bottles sold in the morning

we know that

Ann sold 314 bottles of drinks a day

$x+y=314$ -----> equation A

She sold 66 bottles more in the afternoon than in the morning

$x=y+66$ ----> equation B

substitute equation B in equation A

$y+66+y=314$

solve for y

$2y=314-66\\2y=248\\y=124$

therefore

Ann sold 124 bottles of drinks in the morning

For a normal distribution, the z value for an x value that is to the right of the mean is always:

Dmitry_Shevchenko [17]

In a normal distribution, the z value for an x value that is to the right of the mean will always be positive while on the other hand if the z value for an x value that is to the left of the mean it will always be negative. It is because left side is always negative and right side is always positive.
