Answer:

a   10 yd   2ft  7 in

b 10 yd  1 ft  2 in

c  99 yd

d.  4840 sq  yd  7 sq ft  119 sq in  

Step-by-step explanation:

a.      2 ft. 5 in. +

9 yd. 3 ft. 2 in.

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

9 yd   5ft   7 in

but 3 ft = 1yd

9 yd   5ft   7 in

+1yd   - 3ft

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

10 yd   2ft  7 in



b. 4 yd. 8 in

+ 6 yd. 6 in.

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

10 yd   14 in

but 12 in = 1ft


10 yd       14 in

     + 1ft   - 12 in

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

10 yd  1 ft  2 in



c. 29 yd. 2 ft. 11 in.

  55 yd. 1 ft. 10 in.

+ 13 yd. 1 ft. 3 in.  

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

97 yd   4 ft   24 in

12 in = 1ft

24 in = 2ft


97 yd   4 ft   24 in

           +2ft    - 24 in

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

97 yd   6ft

3 ft = 1yd

6f = 2yd


97 yd   6ft

+2yd   - 6ft

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

99 yd


d. 4,839 sq. yd. 8 sq. ft. 139 sq. in.

                      + 7 sq. ft. 124 sq. in.

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

  4839  sq yd  15 sq ft   263 sq in

12*12 = 144 sq in = 1 sq ft

 4839  sq yd  15 sq ft   263 sq in

                       + 1 sq ft  - 144 sq in

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

4839  sq yd  16 sq ft  119 sq in

3ft * 3 ft = 9 sq ft = 1 sq yd

4839  sq yd  16 sq ft  119 sq in

      +1 sq yd  - 9 sq ft

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

4840 sq  yd  7 sq ft  119 sq in

Answer:

We need to solve given additions of measurements.

We use following conversion to simplify the answer.

1 yard = 3 foot

1 foot = 12 inches

1 square yard = 9 square foot

1 square foot = 144 square inches

Now,

1). 2 ft. 5 in. + 9 yd. 3 ft. 2 in.

           2 ft. 5 in.

+  9 yd. 3 ft. 2 in.  

_______________

= 9 yd.  5 ft. 7 in.

Using Conversion scale, 5 ft = 1 yd 2 ft

9 yd 5 ft 7 in = 10 yd   2ft  7 in

2).  4 yd. 8 in + 6 yd. 6 in.

  4 yd. 8 in

+ 6 yd. 6 in.  

__________

= 10 yd. 14 in.

Using Conversion scale, 14 in = 1 ft 2 in

10 yd 14 in  = 10 yd 1 ft 2 in

3). 29 yd. 2 ft. 11 in. + 55 yd. 1 ft. 10 in. + 13 yd. 1 ft. 3 in.

  29 yd. 2 ft. 11 in.

+ 55 yd. 1 ft. 10 in.

+ 13 yd. 1 ft.   3 in.

_______________

= 97 yd. 4 ft.  24 in.

Using Conversion scale, 24 in = 2 ft  

97 yd 4 ft  24 in = 97 yd 6 ft

Again  Using Conversion scale, 6 ft = 2 yd

97 yd 6 ft = 99 yd

4). 4,839 sq. yd. 8 sq. ft. 139 sq. in. + 7 sq. ft. 124 sq. in.

  4,839 sq. yd.     8 sq. ft.    139 sq. in.

+                             7 sq. ft.   124 sq. in.

______________________________

=  4839  sq yd.     15 sq ft.    263 sq in.

Using Conversion Scale, 263 sq in = 1 sq ft 119 sq in

4839  sq yd  15 sq ft   263 sq in = 4839 sq yd 16 sq ft 119 sq in

Again  Using Conversion scale, 16 sq ft =  1 sq yd 7 sq ft

4839 sq yd 16 sq ft 119 sq in = 4840 sq yd 7 sq ft 119 sq in

Sav [38]
The volume of the pyramid is a third of the volume of the prism which has the same base area and height as the pyramid. That is,
V = b²h / 3
Substituting the variables given,
V = (s²)(0.5s) / 3
Simplifying,
V = s³/6

Part 1!
kondaur [170]
1.  We have to find the fifth term of f(n) = 7 - 4(n - 1). 
That means x = 5. Substitute 5 into the equation for x. 
f(n) = 7 - 4(5 - 1) 
Subtract 5 - 1. 
f(n) = 7 - 4(4) 
Multiply 4 by 4. 
f(n) = 7 - 16 
Subtract 16 from 7. 
f(n) = -9 
The answer is D. 

2. Since we have to find the first 4 terms, we have to solve for x = 1, 2, 3, & 4. 
Multiply 1, 2, 3, and 4 by 6. We now have: 
f(x) = 6 - 25   f(x) = 12 - 25   f(x) = 18 - 25   f(x) = 24 - 25 
Subtract 25 from the first term: 6, 12, 18, and 24. 
f(x) = -19   f(x) = -13   f(x) = -7   f(x) = -1 
The answer is C. 

3. Now, we have to find the first 3 terms of f(x) = 10(2)^x.  So x is 1, 2, & 3. 
Raise 2 to the powers of 1, 2, and 3. The equations are now: 
f(x) = 10(2)   f(x) = 10(4)   f(x) = 10(8) 
Then multiply 10 by the three terms: 2, 4, and 8. 
f(x) = 20   f(x) = 40   f(x) = 80 
The answer is A. 

4. Find the 21st term of f(n) = 2 + 9(n - 1). Substitute 21 for n. 
f(n) = 2 + 9(21 - 1) 
Subtract 1 from 21. 
f(n) = 2 + 9(20) 
Multiply 9 by 20. 
f(n) = 2 + 180
Add 2 to 180. 
f(n) = 182 
The answer is B. 

5. Which sequence is described by f(n) = 2(3)^x-5. 
This is the only one which I'm not sure how to solve. Since I don't know, I won't answer it because I don't want to give you the wrong answer to the question, sorry about that. 

6. The ninth term in f(n) = 384(1/2)^n-1. Put 9 in for n & subtract 1 from 9. 
f(n) = 384(1/2)^8 
Raise 1/2 to the power of 8.
f(n) = 384(1/256) 
Multiply 1/256 by 384. 
f(n) = 384/256 
Reduce the fraction & make it a mixed number. 
f(n) = 1 1/2 

Hope this helped!

11/4 hours 19/8 hours 2.6 hours witch is closest to 2 hours?
ExtremeBDS [4]

Answer:

\frac{19}{8} hours is closest to 2 hours.

Step-by-step explanation:

We have been given three numbers and we need to decide which of the three numbers is closest to 2.

In order to decide that, we will convert each of the given numbers into decimals and then we will compare.

\frac{11}{4} =2.750\\\frac{19}{8}=2.375\\2.6=2.600

Upon comparing 2.750, 2.375 and 2.600 we know that 2.375 is closest to 2. Therefore, out of the given three numbers, \frac{19}{8} is closest to 2.
