Answer:

  s ≥ 60

Step-by-step explanation:

If Scott earned 20 points more on this test, then he earned 20 points less on the last test. 20 points less than "at least 80" is "at least 60."

  s ≥ 60

9/2{8-x}+36=102-5/2{3x+24}
you first use 9/2 to open brackets
9/2*8=36,
9/2*x=9/2x
36-9/2x=102-5/2{3x+24}
5/2*3x=15/2x+60
36-9/2x=-15/2x-60
36+60=15/2x+9/2x
96=12x you then divide and the answer obtained will be 8.
x=8

coldgirl [10]

Answer:

( 5 - 2t ) < - 4

Step-by-step explanation:

The midnight temperature is 5 °C and the temperature is decreasing at the rate of 2°C per hour.

If t is the hours past midnight then after t hours the temperature will be ( 5 - 2t ).

Now, if this temperature is colder than - 4° C, then the inequality can be written as   ( 5 - 2t ) < - 4 (Answer)

<h2>Hello!</h2>

The answer is:

The correct option is:

B) 15

<h2>Why?</h2>

To solve the problem, we need to use the Pythahorean Theorem. We know that we can use the theorem since we are working with a right triangle as we can see in the picture.

So, we are given the following information:

Hypothenuse=c=25units\\\\Opposite=b=20units

Now, using the Pythagorean Theorem, we have:

c^{2}=a^{2} +b^{2} \\\\25^{2}=a^{2}+20^{2}\\\\a^{2}=25^{2}-20^{2}=225\\\\a=\sqrt{225}=15

Hence, we have that the correct option is:

B) 15

Have a nice day!
