162 cow-days

Since the initial grass and the grass accumulated over 4 days is equal to 144 cow-days, the initial grass is equal to (144 − 36) or 108 cow-days. Now, to find the answer to the question: in 18 days, the grass accumulation is equal to 18 ∗ 9 or 162 cow-days.

V=hpir^2

I will assume that the first one is the one with radius 16 and height 40
2nd is radius 7 and height 26

1. v=hpir^2
v=40pi16^2
v=40pi256
v=10240pi cubic inches
3rd option

2.
v=hpir^2
v=26(3.14)7^2
v=26(3.14)(49)
v=1274(3.14)
v=4000.36 cubic cm

What is the sum of the exterior angles of a 54-gon?

oksian1 [2.3K]

Answer: The sum of the exterior angles of a 54-gon should be 360°.

Step-by-step explanation:

A polygon is a closed figure made up of straight lines like triangle (3-gon) , quadrilateral (4-gon) , square(4-gon), pentagon (5-gon) , octagon(8-gon) etc.

The sum of exterior angles of any polygon with n sides ( or n-gon ) is always 360 degrees.

A 54-gon is a polygon with 54 sides.

Therefore , the sum of the exterior angles of a 54-gon should be 360°.

Need some help with number word problems, tysm if you do :)

lord [1]

Answer:

Read below

Step-by-step explanation:

x is always the smaller number

y is always the larger number

underlined means it's the question

bolded means it's the answer

1.

One number is 6 times as large as another. Their sum is 42. Find the numbers.

The numbers need to fit the criteria:

6x=y
x+y=42

A. 6+36=42 (correct)

B. 7+42=49 (incorrect)

C. 7+35=42 (incorrect because it doesn't follow the 1st rule)

D. 6+42=48 (incorrect)

Only A. 6, 36 fits the criteria.

2.

One number is 3 less than another. Four times the smaller is 4 more than 3 times the larger. Find the numbers.

The numbers need to fit the criteria:

x+3=y
4x-4=3y

4+3=7

12-6≠21 (incorrect)

7+3=10

28-3≠30 (incorrect)

13+3=16

52-4=48 (correct)

9+3≠13 (incorrect)

Only C. 13, 16 fits the criteria.

3.

One number is 4 less than another. Five times the smaller is 3 less than 4 times the larger. Find the numbers.

The numbers need to fit the criteria:

x+4=y
5x+3=4y

13+4=17

65+3=68 (correct)

-23+4= -19

-115+3≠ -76 (incorrect)

17+4=21

85+3≠84 (incorrect)

-11+4+ -7

-35+3≠ -33 (incorrect)

Only A. 13, 17 fits the criteria.

4.

The sum of two numbers is 23. When three times the smaller is subtracted from the larger, the result is 3. Find the numbers.

The numbers need to fit the criteria:

x+y=23
y-3x=3

5+18=23

18-15=3 (correct)

8+15=23

15-24≠3 (incorrect)

-13+36=23

36+39≠3 (incorrect)

-5+28=23

28+15≠3 (incorrect)

Only A. 5, 18 fits the criteria.

5.

The sum of two numbers is 26. When twice the smaller is subtracted from the larger, the result is 2. Find the numbers.

The numbers need to fit the criteria:

x+y=26
y-2x=2

8+18=26

18-16=2 (correct)

9+17=26

17-18≠2 (incorrect)

7+19=26

19-14≠2 (incorrect)

6+20=26

20-12≠2 (incorrect)

Only A. 8, 18 fits the criteria.
