Answer:

1. 1,016 sq. m.

2. 119 sq. m.

Step-by-step explanation:

14 x 18 = 252

18 x 8 = 144

14 x 8 = 112

2 ( 252 ) + 2 ( 144 ) + 2 ( 112 )

504 + 288 + 224 = 1,016 sq m

4 (7 x 5 divided by 2) + (7 x 7) =

7 x 5= 35 divided by 2 = 17.5 x 4 = 70 + 49 = 119 sq. m.

Hello, I would really like some help on this!! Please leave an explanation of how you got your answer! Thank You!

Answers

1a) To find the total area, you must find the area of the triangular part that is missing, then subtract this from the area of the rectangle. For the triangle’s area, you need to know the width (2m) and length (2m). For the rectangle’s area you need to know the width (3m) and length (4m).
1b) the total area is 10m^2 (10 meters squared). This is found by subtracting the triangle (.5x2x2=2) from the rectangle (3x4=12).

Explain similar figures including explaining how to find the scale factor when given two similar figures and side lengths.

Answers

similar figures are two different figures of different sizes, but have the same shape

Suppose you have two similar figures , one larger than the other. The scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure. Here, XYUV=123=4 . So, the scale factor is 4 .

Eileen's Energy Bars has determined that an energy bar measuring 3.25 inches long has a z-score of +1 and an energy bar measuring 3.50 inches long has a z-score of +2.

What is the standard deviation of the length of energy bars produced at Eileen's Energy Bars?

3.5
3.25
0.75
0.25

Answers

Answer:

0.25

Step-by-step explanaition:

The z-score represents how many deviations a value is from the mean. When the bar measures 3.25, the z-score is +1. When the bar measures 3.50, the z-score is +2. You'll notice that whenever the bar size increases by 0.25, the z-score goes up +1. So, the standard deviation from the mean must be 0.25.

With you here, and with us in my own home, in the long run, success or failure will be conditionedupon the way in which the average man, the average women, does his or her duty, first in the ordinary, every-day affairs of life, and next in thosegreat occasional cries which call for heroic virtues. The average citizen must be a good citizen if our republics are to succeed. The stream will notpermanently rise higher than the main source; and the main source of national power and national greatness is found in the average citizenshipof the nation. Therefore it behooves us to do our best to see that the standard of the average citizen is kept high; and the average cannot bekept high unless the standard of the leaders is very much higher.Let the man of learning, the man of lettered leisure, beware of that queer and cheap temptation to pose to himself and to others as a cynic, asthe man who has outgrown emotions and beliefs, the man to whom good and evil are as one. The poorest way to face life is to face it with asneer. There are many men who feel a kind of twister pride in cynicism, there are many who confine themselves to criticism of the way others dowhat they themselves dare not even attempt. There is no more unhealthy being, no man less worthy of respect, than he who either really holds,or feigns to hold, an attitude of sneering disbelief toward all that is great and lofty, whether in achievement or in that noble effort which, even ifit fails, comes to second achievement. A cynical habit of thought and speech, a readiness to criticise work which the critic himself never tries toperform, an Intellectual aloofness which will not accept contact with life's realities - all these are marks, not as the possessor would fain to think,of superiority but of weakness. They mark the men unfit to bear their part painfully in the stern strife of living, who seek, in the affection ofcontempt for the achievements of others, to hide from others and from themselves in their own weakness. The role is easy; there is none easler,save only the role of the man who sneers alike at both criticism and performance. last one! Please help me !!
