Answer:

v = at + 16 {t}^{2}  \\ v - 16 {t}^{2} = at \\  \frac{v - 16 {t}^{2} }{t}   = a \\ (27 - 16 \times  {4}^{2})   \div 4  = a\\  \frac{27 - 256}{4}   = a\\   \frac{ - 229}{4}  =  - 57.25 \\ thank \: you

Evaluate the expression. 0.1×( – 0.9+ – 0.2÷ – 0.5) Write your answer as an integer or a decimal. Do not round.
matrenka [14]

Answer:

-0.05

Step-by-step explanation:

Given the expression :

0.1×( – 0.9+ – 0.2÷ – 0.5)

Evaluating the bracket :

0.1 * (-0.9 - 0.2 ÷ - 0.5)

Solving the division first

-0.2 ÷ - 0.5 = 0.4

Now we have ;

0.1 * (-0.9 + 0.4)

0.1 * - 0.5

= - 0.05

B is the midpoint of A . If AB = x+5 and BC =2x-11, find the measure of AB
nignag [31]

If B is the midpoint of AC, then AB = BC.

We have AB = x + 5 and BC = 2x - 11.

Therefore we have the equation:

x + 5 = 2x - 11       <em>subtract 5 from both sides</em>

x = 2x - 16       <em>subtract 2x from both sides</em>

-x = -16      <em>change the signs</em>

x = 16

Put the value of x to the expression x + 5:

AB = 16 + 5 = 21

<h3>Answer: AB = 21</h3>
