Kaitlyn drove 360 miles in 9 hours. If she continues driving at the same speed, how far will she have driven in 11 hours?

stellarik [79]

Answer:

440 miles

Step-by-step explanation:

First, you need to calculate the number of miles per hour. To do this, take the total number of miles traveled and divide it by the number of hours it took. 360/9=40. This means Kaitlyn drove at 40 miles per hour. Then, we need to multiply 40 by 11 to figure out the number of miles she drove in 11 hours because her speed stayed the same. 40*11=440. This means Kaitlyn will have driven 440 miles in 11 hours.

Hope this helps! :)

Solve for x: 2 over 5 (x − 2) = 4x. (1 point) 2 over 9 9 negative 2 over 9 negative 9 over 2

Natalka [10]

<u>ANSWER</u>

$x = - \frac{2}{9}$

<u>EXPLANATION</u>

The given equation is :

$\frac{2}{5}(x - 2) = 4x$

We multiply both sides by $\frac{5}{2}$

$\frac{5}{2} \cdot\frac{2}{5}(x - 2) = 4x \times \frac{5}{2}$

We simplify to obtain:

$x - 2 = 10x$

Group similar terms to obtain:

$- 2 = 10x - x$

Simplify the right hand side.

$- 2 = 9x$

Divide both sides by 9.

$\frac{ - 2}{9} = \frac{9x}{9}$

$- \frac{2}{9} = x$

Or

$x = - \frac{2}{9}$

The second choice is correct

How many primes occur between 0 and 230,948,202? (Note: the answer is the number of primes, not the primes themselves!) Answer C

daser333 [38]

Answer:

There are approximately 27,613,774 primes between 0 and 230,948,202

Step-by-step explanation:

The Prime Number Theorem states that between 0 and $x$ , the number of primes in this interval can be approximated by the following formula.

$\pi(x) = \frac{x}{log x}$

So

How many primes occur between 0 and 230,948,202?

This is approximately $\pi(230,948,202)$

So

$\pi(230,948,202) = \frac{230,948,202}{\log{230,948,202}} = 27,613,774$

There are approximately 27,613,774 primes between 0 and 230,948,202
