I have to find the surface area of a cereal box. (ohs cereal)
ladessa [460]

Answer:

366 square inches

Step-by-step explanation:

Surface Area Formula:

A= 2( w*l + h*l + h*w)

So you substitute the numbers:

A= 2(3*9 + 13*9 + 13*3)

A= 2( 27+ 117 + 39)

A= 54+234+78

A= 366 square inches

There you go :)

The time taken to prepare the envelopes to mail a weekly report to all executives in a company has a normal distribution, with a
telo118 [61]

Answer:

Mailing preparation takes 38.29 min max time to prepare the mails.

Step-by-step explanation:

Given:

Mean:35 min

standard deviation:2 min

and 95%  confidence interval.

To Find:

In normal distribution mailing preparation time  taken less than.

i.eP(t<x)=?

Solution:

Here t -time and x -required time

mean time 35 min

5 % will not have true mean value . with 95 % confidence.

Question is asked as ,preparation takes less than  time means what is max time that preparation will take to prepare mails.

No mail take more time than that time .

by Z-score or by confidence interval is

Z=(X-mean)/standard deviation.

Z=1.96 at  95 % confidence interval.

1.96=(X-35)/2

3.92=(x-35)

X=38.29 min

or

Confidence interval =35±Z*standard deviation

=35±1.96*2

=35±3.92

=38.29 or 31.71 min

But we require the max time i.e 38.29 min

And by observation we can also conclude the max time from options as 38.29 min.

an ice fisherman wishes to cut a hole in the ice which has a diameter of 30 cm. How far around must he cut to create this hole?
olga55 [171]

Given:

Diameter of the hole = 30 cm

To find:

The area of the hole.

Solution:

The radius of a circle is always half of the diameter. It is given that the diameter of the hole is 30 cm. So, the radius of the hole is:

r=\dfrac{30}{2}

r=15

Area of a circle is:

A=\pi r^2

Putting \pi = 3.14 and r=15 in the above formula, we get

A=(3.14)(15)^2

A=(3.14)(225)

A=706.5

Therefore, the area of the hold is 706.5 square cm.

Fish food is $3.50. An aquarium is $10.00. A filter system costs $9.95. Gravel and plants are $6.25. Mike has $30.00 to spend. H
Veronika [31]

Add all the prices together:

3.50 + 10.00 + 9.95 + 6.25 = 29.70

He has 30, so he had 30 - 29.70 = 0.30 left over for fish.

The two fish cost 4.50 + 4.50 = 9.00

He would need 9.00 - 0.30 = $8.70 more money
