2=1.04^t

t=ln2/(ln1.04)

t=17.673 (approx)

so t=18 (although you will have slightly more than double)

A car traveling 281 miles 4 hours and 40 minutes what was the average speed of the car in miles per hours

den301095 [7]

ok this one is tricky but I think I can handle it.

The correct answer is more than 60mph but less than 61mph.

60.3mph = 281.399598

or 60.2mph =280.932932

Those are my closest answers.

I really hope this helps

Which expression would be equivalent to: Which expression would be equivalent to: \frac{1+b}{2} - 3(a-1)

IrinaVladis [17]

Answer:

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+7}{2}$

Step-by-step explanation:

Given

$\frac{1+b}{2} - 3(a-1)$

Required

An equivalent expression

$\frac{1+b}{2} - 3(a-1)$

Take LCM

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 2*3(a-1)}{2}$

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 6(a-1)}{2}$

Open bracket

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 6a+6}{2}$

Collect like terms

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+6+1}{2}$

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+7}{2}$

Hence, an equivalent expression is:

$\frac{b- 6a+7}{2}$

What are the solutions of the quadratic equation below?

Ksenya-84 [330]

Use the quadratic formula -b +/-√(b^2-4(ac)) / 2a

In the given formula a = 7, b = 23 and c = -10

Replace the letters with their values:

-23 +/-√(23^2 -4*(7*-10)) / 2*7

Simplify to get:

x = -23 + √809 / 14 or x = -23 - √809 / 14
