Average speed = total distance / total time...

s=3.5/0.5=7mph

3 1/2 miles = 7/2 miles
1/2 hours= 30 minutes
So,
In 30 mins, travelled 7/2 miles
In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles
In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.
Hence, the speed is 7 miles per hour. Anything else

In 2008, the total trade between the United States and Japan was $2.04 x 101^1. The total trade between the U.S. And Australia w
jolli1 [7]

Answer:

6.21 times more

Step-by-step explanation:

Assuming 2.04 x 10^11 was only a typo

you would need to first equal the powers of 10

so 20.4 x 10^10 and 3.28 x 10^10

now that they have the same powers

\frac{20.4 * 10^{10}}{3.28 * 10^{10}}  = \frac{20.4}{3.28} = 6.219512...

if it's asking for how many times i would approximate it to 6.21 times more

ASAP PLZZZ The axis of symmetry for the graph of the function f start bracket x end bracket equals one-quarter x square plus b x
Lilit [14]

Answer:

b=-3

Step-by-step explanation:

The  given function is f(x)=\frac{1}{4}x^2+bx+10.

When we compare to ax^2+bx+=0, we have

a=\frac{1}{4} and c=10

The equation of the axis of symmetry of a vertical parabola is:

x=-\frac{b}{2a}

Also from the question the axis of symmetry is x=6

We substitute the values to get:

6=-\frac{b}{2*\frac{1}{4}}

6=-\frac{b}{\frac{1}{2}}

b=-\frac{1}{2}*6

b=-3
