You but a container of cat litter for 12.25 and a bag of cat food for x dial let's. The total is 19.08 witch includes 6% tax sales. Write and solve an equation to find the cost of the cat food.

Answers

Answer 1
Answer:

Answer:

The price of cat food is 5.75 dial

Step-by-step explanation:

Given as :

The price of container of litter = 12.25 dial

The price of cat food  = x  dial

The total price of items = 19.08 dial including 6% sales tax

So, The total price of item excluding sales tax is A

Or, A + 6% of A = 19.08

So, 1.06 × A = 19.08

Or, A = (19.08)/(1.06)

∴   A = 18 dial

Now, The price of cat food = Total price of item excluding tax - price of container of litter

Or,  The price of cat food = 18 dial - 12.25 dial

∴  The price of cat food = 5.75 dial

Hence The price of cat food is 5.75 dial    Answer

If sin A = .5 and cos A = .866 then what is tan A to the nearest thousandth

Answers

Somewhere in a table of trig-function definitions that you have somewhere,
it mentions that

            tan(a)  =  sin(a) / cos(a).

So it must follow that

            tan(A)  =  (0.500) / (0.866)  =  0.577  (rounded)  

What is 8.2p-33.4=1.7-3.5p

Answers

8.2p-33.4=1.7-3.5p 

8.2p=1.7-3.5p+33.4         Add \ 33.4 \ to \ both \ sides

8.2p=-3.5p+35.1 

8.2p+3.5p=35.1                   Add \ 3.5p \ to \ both \ sides

11.7p=35.1 

(11.7p)/(11.7) = (35.1)/(11.7p)             Divide \ both \ sides \ by \ 11.7

p=3       Solution
p=3
First you add 33.4 to both sides. Then add 3.5p to both sides. Then divide 35.1 by 11.7 and you get 3. 

Every prime number greater than 10 has a digit in the ones place that is include in wich set of numbers A- 1,3,7,9 B-1,3,5,9 D-1,3,7

Answers


That's very interesting.  I had never thought about it before.
Let's look through all of the ten possible digits in that place,
and see what we can tell:

-- 0:
   A number greater than 10 with a 0 in the units place is a multiple of
   either 5 or 10, so it's not a prime number.

-- 1:
    A number greater than 10 with a 1 in the units place could be
    a prime (11, 31 etc.) but it doesn't have to be (21, 51).

-- 2:
   A number greater than 10 with a 2 in the units place has 2 as a factor
   (it's an even number), so it's not a prime number.

-- 3:
   A number greater than 10 with a 3 in the units place could be
   a prime (13, 23 etc.) but it doesn't have to be (33, 63) .

-- 4: 
   A number greater than 10 with a 4 in the units place is an even
   number, and has 2 as a factor, so it's not a prime number.

-- 5:
   A number greater than 10 with a 5 in the units place is a multiple
   of either 5 or 10, so it's not a prime number.

-- 6:
   A number greater than 10 with a 6 in the units place is an even
   number, and has 2 as a factor, so it's not a prime number.

-- 7:
   A number greater than 10 with a 7 in the units place could be
   a prime (17, 37 etc.) but it doesn't have to be (27, 57) .

-- 8:
   A number greater than 10 with a 8 in the units place is an even
   number, and has 2 as a factor, so it's not a prime number.

-- 9:
   A number greater than 10 with a 9 in the units place could be
   a prime (19, 29 etc.) but it doesn't have to be (39, 69) .

So a number greater than 10 that IS a prime number COULD have
any of the digits  1,  3,  7,  or  9  in its units place.

It CAN't have a  0,  2,  4,  5,  6,  or  8 .

The only choice that includes all of the possibilities is  'A' .

You want to produce a scale drawing of your living room, which is 21 ft by 28 ft. If you use a scale of 5 in. = 7 ft, what will be the dimensions of your scale drawing?

Answers

Answer:

15 in. by 20 in.

Step-by-step explanation:

Dimensions of living room :

Length = 21 feet

Width = 28 feet

Scale : 5 in. = 7 ft

So, 1 ft. = (5)/(7) in.

So, 21 feet = 21 * (5)/(7) in.

21 feet = 15 inches

Now 28 feet = 28 * (5)/(7) in.

28 feet = 20 inches

So, the dimensions of the scale drawing = 15 in. by 20 in.

Hence the dimensions of the scale drawing is 15 in. by 20 in.                                                      

5 in --------- 7 ft
x in  --------- 21 ft

x = (5 x 21)/7=15 in

Otherwise:

5 in ---------- 7 ft
x in  ---------- 28 ft

x = (5 x 28)/7 = 20 in

Dimentions of drawing is 15 x 20 in
