a long distance telephone company charges a rate of 8 cents per minute or 90 cent mininum charge per call, whichever is greater. Find the cost in cents per minute for a 41 minute call.

Answers

The cost of a 41 min call would be 328 cents. So, that would be 8 cents per minute, because the charge of the call is greater that 90 cents. Hope that helps!!

Which mathematical sentence most accurately expresses the information in the problem below? Crystal has 121 compact discs that she wants to put into boxes. Each of the boxes that she brought home holds 25 discs. How many of these boxes will she need for all of her discs?

Answers

Crystal has 121 compact discs. The total number of boxes required are 5.

Solution:

Given, Crystal has 121 compact discs that she wants to put into boxes.

Each of the boxes that she brought home holds 25 discs.

We have to find how many of these boxes will she need for all of her discs?

Now, we know that, number of boxes required $=\frac{\text {total number of discs}}{\text {capacity of one box}}=(121)/(25)=4.84=5$

Here we took 5 because 0.84 means that box with discs less than 25 still we require a box.

Hence, the total number of boxes required are 5.

The product of (3+2i) and a complex number is (17+7i)

What is the complex number.

Answers

The question is asking us to find the complex number such that: ( 3 + 2 i ) * x = 17 + 7 i. We know that i^ 2 = - 1. x = ( 17 + 7 i ) / ( 3 + 2 i ) . We have to multiply the numerator and the denominator by ( 3 - 2 i ). Then: x = ( 17 + 7 i ) * ( 3 - 2 i ) / ( 9 - 4 i^2 ) = ( 51 - 34 i + 21 i - 14 i^2 ) / ( 9 + 4 ) = ( 51 + 14 - 13 i ) / 13 = ( 65 - 13 i ) / 13 = 65 / 13 - 13 i / 13 = 5 - i. Answer: The complex number is 5 - i.

The average performance rating of the employees at Company A is 6.5 on a scale from 1 to 10 (10 being highest). The standard deviation is 2.1 The average performance rating of the employees at Company C is 7.4. Company C has a standard deviation of 6.8. It would be better to hire a random employee from Company A. Question 2 options:

Answers

The best choice based on the standardsdeviation will be to hire an employee from company A.

How to illustrate the information?

From the information given, the z value to company A will be:

= (6.5 - 5.5)/2.1

= 0.7142

The z value to company B will be:

= (7.4 - 5.5)/6.8

= 0.2794

Therefore, the best choice based on the standards deviation will be to hire an employee from company A since they've higher performance rating.

At a skills competition, a target is being lifted into the air by a cable at a constant speed. An archer standing on the ground launches an arrow toward the target. The system of equations below models the height, in feet, of the target and the arrow t seconds after it was fired. Which statement most likely describes the situation modeled by this system?h=8+2t
h=4+32t-16t^2

1The arrow is fired with an initial upward velocity of 2 ft/s.
2The arrow is fired with an initial upward velocity of 4 ft/s.
3The arrow is fired with an initial upward velocity of 8 ft/s.
4 The arrow is fired with an initial upward velocity of 32 ft/s.

Answers

By definition, the equation of movement in its generic form is given by:

$h(t) = -(1)/(2)gt^2 + v0t + h0$

Where,

g: acceleration due to gravity

v0: initial speed

h0: initial height

The equation for the arrow is given by:

$h = 4 + 32t-16t ^ 2$

Then, according to the definition, the initial velocity of the arrow is:

$v0 = 32$

Answer:

4 The arrow is fired with an initial upward velocity of 32 ft / s.

From the kinematic equations, s(t) = s_in + (v_in)(t) – (1/2)(g)(t^2). This means that there is an initial distance of 4, initial velocity of 32 and acceleration (in opposite direction of the motion) of 32. Option 4 shows the correct answer.

What is the sum of 3/8 and 1/16

Answers

make the denominators the same before you add so,
$(6)/(16)$ + $(1)/(16)$ = $(7)/(16)$

$(3)/(8) = (6)/(18) (6)/(16) + (1)/(16) = (7)/(16)$
