What number is represented by point P?
likoan [24]

Answer:

0.0057

Step-by-step explanation:

  • Narrow it down.
  • The point P is between 5 * 10^-3 and and 6*10^-3
  • When you go to the bottom line, P is on the 7th division from the left.
  • Going from left to right increases P
  • P is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.
  • One of the answers is 5.7 * 10^-3
  • The other answer is .0057
  • I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it.
  • If it is not correct, then 5.7 * 10^-3 is the answer.

Helllpppppppppp please someone.?????
Liula [17]

Answer:

(-5,5)

Step-by-step explanation:

Multiply the first equation by -2,and multiply the second equation by 1.

−2(x+5y=20)

1(2x−7y=−45)

Becomes:

−2x−10y=−40

2x−7y=−45

Add these equations to eliminate x:

−17y=−85

Then solve−17y=−85for y:

(Divide both sides by -17)

y=5

x+5y=20

Substitute  5 for y in x+5y=20:

x+(5)(5)=20

x+25=20(Simplify both sides of the equation)

x+25+−25=20+−25(Add -25 to both sides)

x=-5

A producer is said to have an absolute advantage over another producer when he required less amount of input to produce the same good compared to the other producer.

While a producer is said to have a comparative advantage over another producer when he produces his goods at a lesser opportunity cost compared to the other produer.

Here, time is one of the inputs used in production and Maria produces a scarf at a lesser time compared to Sofia. Thus, Maria has an absolute advantage over Maria in the production of scarves.

Therefore, the true statement is "<span>Maria has an absolute advantage over Sofia".</span>

Find the length of the third side to the nearest tenth 6 and 9
oee [108]

Hello, i do believe that you are asking me to do pythagorean theorem.

I'm not too sure if we are solving hypotenuse or a/b so i'll do both.

\boxed{\underline{Hypotenuse...}}\\\\\\A^2+B^2=C^2\\6^2+9^2=C^2\;\\36+81=117

\sqrt{117}=10.816\\Round-\;10.8

\boxed{\underline{a/b...}}\\\\\\A^2=C^2-B^2\\A^2=9^2-6^2\\A^2=81-36\\A^2=45\\\sqrt{45}= 6.708\\Round-\;6.7

Hope it helps!

Sonja [21]

Answer: The new boxes are 14 ft3 larger.

Step-by-step explanation:

Hi, to answer this question we have to calculate the volume of each box and compare them.

Volume of a rectangular prism = base x height x length

Replacing with the values given:

Old boxes volume: 4 x 2 x 2 =16 cubic feet

New boxes' volume: 3 x 5 x 2 = 30 cubic feet

Subtraction the old boxes volume to the new boxes volume:

30 ft3- 16 ft3 = 14 ft3

The new boxes are 14 ft3 larger.
