Lilly has $35,she went to the store and spender 10% of it,how much money she has left?

kirill115 [55]

Hi there! Lily has $31.50 left.

To find our answer we first need to know the amount of money Lily spend.
$10\% \times 35 = 0.1 \times 35 = 3.50$

Therefore, Lily spend $3.50. Now we subtract this amount of money from the amount she initially owned.

$35 - 3.50 = 31.50$
Hence, Lily has $31.50 left.

The table below represents the distance of an airplane from its destination as a function of time:

Ira Lisetskai [31]

Let us first find the equation for the distance as a function of time in the form:

d=mx+b

m=(d2-d1)/(x2-x1)

m=(2160-2700)/(1-0)

m=-540

d=-540x+b, using point (0,2700) we can solve for b

2700=-540(0)+b

2700=b so

d(x)=-540x+2700

A) The y-intercept is the constant of our distance function (the distance when x, time, equals zero). In this case d=2700 is the y-intercept. This means that the initial distance from the destination was 2700 miles.

B) Since this is just a line and has a constant velocity, its average velocity will just be the constant velocity or slope. But mathematically we could show this to be true. Average velocity is change in distance divided by change in time.

v=(540-2160)/(4-1)

v=-1620/3

v=-540 mph

C)

The domain of a function is the possible x values in the proper context. First time cannot be less than 0. The other extreme for time is when the plane reaches its destination, when d=0, which is when:

-540x+2700=0

540x=2700

x=5.

So the plane reaches its destination after 5 hours. So the domain, the x values, for d=-540x+2700 is

x=[0,5]

Show 46/200 on the hundredths grid. then write the fractions as a demical

SSSSS [86.1K]

If we want to has 100 in the denominator we have to divide numerator and denominator by 2. Then total value of fraction doesnt change.
$\frac{46}{200}= \frac{46:2}{200:2}= \frac{23}{100}$
Now read the fraction, its 23 hundreds, now just write as decimal, so, 0.23
