What is the length of the hypotenuse? If necessary, round to the nearest tenth.
Papessa [141]

<u>Answer:</u>

  • The value of c is 2√2 or about 2.8.

<u>Step-by-step explanation:</u>

<u>We can find the hypotenuse (c) with the help of Pythagoras Theorem.</u>

  • => c² = 2² + 2²
  • => c² = 4 + 4
  • => c² = 8
  • => c = √8
  • => c = √2 x 2 x 2
  • => c = 2√2

<u>If you want further simplification, seek for explanation below.</u>

  • => c = 2√2
  • => c = 2 x √2
  • => c = 2 x 1.414
  • => c = 2.828 = 2.8 (Estimated)

Hence, <u>the value of c is 2√2 or about 2.8.</u>

Hoped this helped.

What steps does Emory need to solve the equation x+7=3x+(-5)
swat32

Answer:

First you need to find what x is equal to.

Step-by-step explanation:

 Since 3x-5 is what you need to find divide 3 by 3x to get x alone and do the same for -5/ 3 which -1.6666667, and you can estimate it to be -1.67 so x is about -1.67.

The time to complete a standardized exam is approximately normal with a mean of 70 minutes and a standard deviation of 10 minus.
AnnyKZ [126]

Answer:

Step-by-step explanation:

Given that the  time to complete a standardized exam is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.

P(completing exam before 1 hour)

= P(less than an hour) = P(X<60)

=P(Z<\frac{60-70}{10} =-1)

=0.5-0.34=0.16

i.e. 16% of students completed the standardized exam.
