a=1/2pa, solve for p
NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!

Answers

Answer 1

Answer:

A = (1/2)Pa = Pa/2

 

You can multiply both sides by 2 to eliminate the fraction on the right side:

 

2A = 2(Pa/2) = Pa

 

Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:

 

(2A)(1/a) = 2A/a = (Pa)(1/a) = P

 

Rewriting:

 

P = 2A/a

 

You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

18.0864 • 22
= $397.9
Answer : $1.2 per cubic foot

Explanation :
1. Do your radius to the power of two and multiply by pi (3.14)
2. That would be 4.5216 you then multiply that by 4(your height) and get about 18
3.You divide 22(cost of oil) by 18(drum of oil) and get about $1.2 per cubic foot

From question:

Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box =Meaning same ratio

John ratio. Susan

s : m : L s : m : L

65 : 40 : 45. 13 : 8 : 9

13 : 8 : 9. x : 176 : y

x = (176/8)*13

=286

y = (176/8) * 9

= 198

Total number of nails in Susan box

Answer: 7/10, 7/10 and 3/10.

Step-by-step explanation:

7/10 = Between 1 and 10, the multiples of three are 3, 6, and 9. So the amount favourable outcomes is the total minus the multiples, 10-3 = 7. So 7/10.

7/10 = Between 1 and 10, the multiples of 2 are 2, 4, 6, 8, and 10. The multiples of 3 are 3, 6 and 9. That, gives 7 favourable outcomes (6 is a multiple of both but counted once) giving the probability of 7/10.

3/10 = The favourable outcome is 8 and above, so: 8, 9 and 10. There are 3 favourable outcomes which gives the probability of 3/10.

You have the 1st one correct...
The second one is 8/10...
The 3rd is 3/10

Answer:

x = 5

Step-by-step explanation:

4x + 2y + z = 24

2x - 3y - z = 2

5x + y + 2z = 21

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

Eliminate z

Add the 1st and 2nd eqn

4x + 2y + z = 24

2x - 3y - z = 2

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

6x - 1y = 26 eqn A

Multiply the 2nd eqn by 2, then add the 3rd.

4x - 6y -2z = 4

5x + y + 2z = 21

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

9x - 5y = 25 eqn B

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

Now you have 2 eqns in 2 unknowns, not 3.

Multiply eqn A by 5 and subtract eqn B.

30x - 5y = 130 eqn A times 5

9x - 5y = 25 eqn B

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

21x = 105

x = 5

Jasraj left his house and walked 1500 m east to the supermarket. He then walked another 500 m east to the comic store before walking back home the same way he came. How many kilometers did Jasraj walk altogether?

Answers

Answer:

Jasraj walked 4 kilometers all together

Step-by-step explanation:

First, add.

1,500 + 500 = 2,000

Then, multiply by 2.

2,000 × 2 = 4,000

Now, we have to convert to kilometers.

1 kilometer = 1000 meters

4,000 ÷ 1,000 = 4

So, Jasraj walked 4 kilometers!
