The measurements obtained for the interior dimensions of a rectangular box are 200 cm by 200 cm by 300 cm. If each of the three

vlada-n [284]

Answer:

C. 160,000

Step-by-step explanation:

Given that the measurements obtained for the interior dimensions of a rectangular box are 200 cm by 200 cm by 300 cm.

Also given that each of the three measurements has an error of at most 1 cm

COnsider the worst case where each dimension is increased by 1 cm

Then we measure the dimensions as 201 , 201 and 301

So volume would be measured as

$201*201*301\\= 12160701$ cubic cm

Actual volume of the box = $200*200*300\\=12000000$ cubic cm

Difference maximum possible = 160701 cubic cm

Out of the five options given option C is nearest to this value

So answer is

C. 160,000

I NEED HELP ON NUMBER 12 AND ALSO NEED EXPLANTION

topjm [15]

picture is blurry but if they are similar find the scale between the known sides

smaller triangle bottom looks like it says 8?

the larger one is 16

8/16 = 0.5 so the smaller one is half the size of the larger one

so half of 8 is 4 so y = 4

since they are similar the angles would stay the same so angle B would be the same as s which is shown as 27 degrees.

One ball is to be selected from a box containing red, white, blue, yellow, and green balls. If the probability that the selected

ZanzabumX [31]

Answer:

30% probability that it will be yellow, or green

Step-by-step explanation:

The urn has red, white, blue, yellow, and green balls.

Each ball is chosen with the following probabilities:

1/10 = 10% probability it is red

2/5 = 40% probability it is white

1/5 = 20% probability it is blue.

p probability it is yellow or green

What is the probability that it will be yellow, or green

The sum of all probabilities is 100%. So

10 + 40 + 20 + p = 100

p = 30

30% probability that it will be yellow, or green
