trasher [3.6K]

John will need to sleep for 10.3 hours before  his second exam so that the

average of his two exam scores is an 80.

We were given

8 hours of sleep = 70

To get average of 80

<u>70+ x</u> = 80

  2

Cross multiply:

70+x = 160

x= 160-70

 = 90.

If  8 hours of sleep = 70

       x hours of sleep = 90

Cross multiply

8× 90 = 70 × x

720 = 70x

x = 720/70

x  = 10.2857

    ≈ 10.3 hours of sleep

Describe the sounds, smells, and sights you associate with spring. Write a paragraph with at least 4 sentences.
spin [16.1K]
Smell: Spring brings soothing scents like lilacs, apple blossoms, hyacinth and daffodils. Sweet aromas turn a stroll through the garden into a delicacy for the nose Springtime means that the trees and flowers come back to life again. After a dead winter, this is a time when we get to see the beautiful flowers blossom again Spring also brings new sounds, like bird songs at dawn, frog croaks by ponds, and dripping icicles. When the weather warms, the sounds you hear in national parks reflect this seasonal change (use this but not in this order fix it up a bit)

LekaFEV [45]

Answer:

The answer is 18 m/s

Explanation:

Vo=0 m/s

acceleration a=3m/s

t=6s

V=Vo +a×t

Vo=0

V=a×t

V=3 m/s^2 ×6 s

V=18 m/s

The vertices of square cdef are c(1, 1), d(3, 1), e(3,−1) and f(1,−1). Which of the following shows that its diagonals are congr
maks197457 [2]

The equation -1 = -\frac {1}{1} shows that the diagonals are congruent perpendicular bisectors.

The vertices of the square are given as:

  • c = (1,1)
  • d = (3,1)
  • e =(3,-1)
  • f = (1,-1)

<h3>How to determine the congruent perpendicular bisectors.</h3>

Start by calculating the slope of diagonal ce using:

m = \frac{y_2 -y_1}{x_2  -x_1}

So, we have:

m = \frac{-1-1}{3  -1}

m = \frac{-2}{2}

m_1 = -1

Next, calculate the slope of diagonal df using:

m = \frac{y_2 -y_1}{x_2  -x_1}

So, we have:

m = \frac{-1-1}{1-3}

m = \frac{-2}{-2}

m_2 = 1

The slopes of both diagonals are:

m_1 = -1

m_2 = 1

By comparing both slopes, we have:

m_1 = -\frac {1}{m_2}

i.e.

-1 = -\frac {1}{1}

Hence, -1 = -\frac {1}{1} shows that the diagonals are congruent perpendicular bisectors.
