Can someone help me with question 16 please?

1 answer:

5 0

Let 's' be the allowed speed.

If the maximum speed is 70 and the minimum is 40, we know 's' is between these two values inclusively, i.e. 40 ≤ s ≤ 70

*Remember for inequality symbols, whether strict or inclusive, the term on narrow side is "less than" the term on the broad side

Answer:

8.4 (42/5)

well you know that 1/4 as a decimal is .25 so take the 5 and put it in front of the .25, so you will have 5.25. And 5/8 as a decimal is .625. then just divide them by using long division or a calculator.

What is the solution to the equation1 over the square root of 8 = 4(m − 2)? (1 point)

kupik [55]

Rationalize the denominator, divide by 4, add 2.
$\dfrac{1}{\sqrt{8}}=4(m-2)\\\\ \sqrt{\dfrac{2}{16}}=4(m-2)\\\\ \dfrac{\sqrt{2}}{4\cdot 4}=m-2\\\\ m=2+\dfrac{\sqrt{2}}{16}$
