Answer:

B is the midpoint, so AB = BC; solve for x, which is 4. Then substitute 4 into 3x+2 (which is DE) and get 14.

Answer:

  x = 6

  AC = 24

Step-by-step explanation:

The midpoint divides the segment into two congruent parts.

  AB = BC

  BC -AB = 0

  x^2 -24 -2x = 0

  (x -1)^2 = 25 . . . . . . add 25, write as a square

  x = 1 +√25 = 6 . . . . only the positive solution is of interest.

AC = 2(AB) = 2(2x) = 4(6) = 24

The value of X is 6, and the length of AC is 24 units.

The answer would be f(x)=9 because when you substitue the 3 in for 'x' you then square the 3.
Hope this helps!

Helpppppppp. Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the
tamaranim1 [39]

Answer:

Jason Inherit a land with a 45% chance of having oil.

Step-by-step explanation:

 The probability of the land having oil is = P ( O) = 45 /100

The probability of the land having oil is= Q(O ) =55/100

The machine has an accuracy of 80%. This suggests that 8 out of 10 times the machine will give a wrong reading.

The probability of the correct reading is=  P(M)=80/100

The probability of the incorrect reading is=Q(M)=20/100

The case when the machine predicts there is no oil and there is indeed oil can be calculated:Probability=Probability of oil present  ×  probability of the incorrect reading

Probability=P(O) x Q(M)

Probability=45/100 x 20/100

Probability=9/100

The probability of the test predicting no oil in land and the land has oil is  0.09 or 9%

For every 4 gallons of green paint he uses 3 gallons of blue paint. Drag the correct number of each type of paint into the box t
Inga [223]

Answer:

Amount of green color used =

\dfrac{64}{7}\text{ gallons}

Step-by-step explanation:

We are given the following in the question:

Every  4 gallons of green paint is mixed with 3 gallons of blue paint. to make a particular shade.

Ratio of green color to blue paint can be calculated as:

=\dfrac{\text{Amount of green color}}{\text{Amount of blue color}}\\\\=\dfrac{4}{3}

Amount of shade = 16

Amount of green paint = 4x

Amount of blue paint = 3x

Thus, we can write:

4x + 3x = 16\\7x = 16\\\\x = \dfrac{16}{7}

Amount of green color used =

4x = 4\times  \dfrac{16}{7} = \dfrac{64}{7}\text{ gallons}

Amount of blue paint used =

3x = 3\times  \dfrac{16}{7} = \dfrac{48}{7}\text{ gallons}
