What are the answers I have to put in the yellow boxes?

valentinak56 [21]

The expression 1x² + 14x + 40 is a quadratic expression, and the answers in the yellow boxes are 40 and 14

<h3>How to complete the boxes?</h3>

The quadratic expression is given as:

1x² + 14x + 40

This implies that:

a = 1

b = 14

c = 40

Because a quadratic expression is represented as:

ax² + bx + c

The expressions in the yellow boxes are:

a * c and b

So, we have:

a * c = 1 * 40 = 40

b = 14

Hence, the answers in the yellow boxes are 40 and 14

Person 1 writes internal operating procedures 3 times faster than Person 2. Most of the procedures took 30 minutes each to creat

ad-work [718]

Person 1 takes 3 hour 10 minutes to complete 9 procedures

<em><u>Solution:</u></em>

From given question,

Person 2 takes 30 minutes per procedure

Person 1 writes internal operating procedures 3 times faster than Person 2

So we get, Person 1 takes 3 times faster than Person 2

Person 1 takes 10 minutes per procedure

But two of the procedures for Person 1 took an hour each

So person 1 takes 60 minutes each for two of procedures ( since 1 hour = 60 minutes )

<em><u>Calculate how long it took Person 1 to complete 9 procedures:</u></em>

So for first 7 procedures person 1 would take 10 minutes per procedure and for last two procedures person 1 would take 60 minutes per procedure

$time $=7$ procedures $\times \frac{10 \text { minutes }}{1 \text { procedure }}+2$ procedure $\times \frac{60 \text { minutes }}{1 \text { procedure }}$$

$time=70 minutes +120minutes\\\\time=190minutes$

We know that,

1 hour = 60 minutes

Therefore,

190 minutes = 60 minutes + 60 minutes + 60 minutes + 10 minutes

190 minutes = 1 hour + 1 hour + 1 hour + 10 minutes = 3 hour 10 minutes

Therefore Person 1 takes 3 hour 10 minutes to complete 9 procedures

Katen [24]

Answer:

Case (c) has the lowest unit price and is thus the best buy.

Step-by-step explanation:

Example: (a) The unit price is the price paid divided by the weight:

$0.50

------------ = $0.2857/oz, or (to 2 decimal places) $0.29/oz

1.75 oz

(b) $1.00/(6 ounces) = $0.17/oz

(c) $1.88/(12 ounces) = $0.16/oz

Case (c) has the lowest unit price and is thus the best buy.
