A cow is tethered to one corner of a barn, 10 feet by 10 feet, with a rope 100 feet long. What is the cows maximum grazing area?

Answers

Answer 1

Answer:

Question???? Is the cow inside or outside of the barn?

We'll assume it is outside the barn because the inside is too easy.

---------------------------------

First we have an area that is 3/4 of a circle with a radius of 100 ft.

area=(3.14*100^2)*3/4=(3.14*10,000)*3/4=31,400*3/4=23,550 ft^2.

now we have a quarter circle with a raduis of 90 ft.

area=(3.14*90^2)/4=(3.14*8,100)/4=25,434/4=6,358.5 ft^2.

as an esimate of the remaining 2 slivers of 5*80+5*90=400+450=950 ft^2 (minus a tad)

adding up these pieces I get 23,550+6,358.5+950=30,858.5 ft^2 (minus the tad)

Try dividing 5/6 and 2 (ex: 2 ÷ 5/6) and I think that you should get your answer.

Which equation finds the volume of a cube with a side length of 2 n Superscript 6 units?(2 n Superscript 6 Baseline) cubed = 8 n Superscript 18 cubic units
(2 n Superscript 6 Baseline) cubed = 2 n Superscript 18 cubic units
2 (n Superscript 6 Baseline) cubed = 2 n Superscript 18 cubic units
2 (n Superscript 6 Baseline) cubed = 6 n Superscript 18 cubic units

Answers

Answer:

Volume of the cube: $8n^(18)$

Step-by-step explanation:

A cube is a solid figure consisting of 6 squared faces arranged in a structure at right angle with each other.

The volume of a cube is given by:

$V=L^3$

where

V is the volume

L is the length of one side of the cube

In this problem, the length of the side of the cube is

$L=2n^6$

Therefore, the volume of the cube is

$V=(2n^6)^3 = 2^3 (n^6)^3 = 8n^(18)$

graces monthly sales totaled $1000. she earns $2000 plus 9% of her sales. what is her total paycheck for this month?

Answers

so 2000+9% of sales
percent means parts out of 100 so 9%=9/100=0.09
'of' means multiply
sale=1000
9% of sales=0.09 times 1000=90
so paychhec=2000+90=$2090

What is the volume enclosed by the slanted prism in the diagram 225cm
270cm
300cm
540cm

Answers

To find the volume of a slanted prism, all you need to know is the area of the base and the height of prism. If you know these two things, then the volume of a prism can be calculated using formula

$V_(prism)=A_(base)\cdot H_(prism).$

Since $A_(base)=25 cm^2$ and $H_(prism)=9 cm,$ you have

$V_(prism)=25\cdot 9=225 cm^3.$

Answer: correct choice is A.

we know that
volume of the slanted prism is equal to
$V=B*h$
where
B is the area of the base------> $B=25 cm^(2)$
h is the height of the prism-----> $h=9 cm$
so
$V=25*9 \n V=225 cm^(2)$

the answer is the option
$225 cm^(2)$

Round 1.0649 to the nearest thousandth

Answers

1.0649 to the nearest thousandths is 1.065

You could get this by finding where the thousandths place is, which is the third number.
Now, look at the number to the right.
If it's 5 or higher, round up.
If it's 4 or lower, round down.

Since it is 9, we round up.
The 4 turns into a 5.

So, 1.065

Hope I helped!
