Yesterday, Anna drank 2/6 of a gallon of milk. Then her sister drank some milk and now there is only 3/12 of the gallon left. Ho

Airida [17]

Answer:

5/12

Step-by-step explanation:

Change the denominator of 6 to 12.

2 x 2 = 4

6 x 2 = 12

Find out how much gallon of milk was drank.

12/12 - 3/12 = 9/12

Find out how much the milk was drank after deducting how much Anna drank.

9/12 - 4/12 = 5/12

jasenka [17]

Answer:

$\$(10-p)$

Step-by-step explanation:

To find much change Nicholas received, simply subtract the cost of granola bar from the amount of money Nicholas paid:

$\$(10-p)$

For example, if granola bar costs p=$4, then Nicholas gets

1. The snow pack on Mt. Hood in the Oregon Cascades was 150 inches on

Damm [24]

Answer:

The rate of change is 10%

Step-by-step explanation:

The computation of the rate of change is as follows:

Given that as on Jan 15, the snow pack is 150 inches

And, the last year, it would decrease by 11 inches a week after jan 15

So, the rate of change is

= 15 ÷ 150

= 10%

Suppose a new regulation that a maximum angle of a ramp for a wheelchairs is 8°. At least how long must the new ramp be? Round t

Llana [10]

Answer:

The length of the ramp is at least 17.2 feet

Step-by-step explanation:

See attachment for the appropriate diagram.

The length of the ramp is represented with z

So, we have:

$\theta = 8$

$BC = 2.4$

Required

Find z

To find z, we make use of sine formula:

$sin\theta = \frac{BC}{z}$

Make z the subject

$z= \frac{BC}{sin\theta }$

So:

$z= \frac{2.4}{sin(8)}$

$z= \frac{2.4}{0.1392}$

$z= 17.2ft$

<em>The length is at least 17.2 feet</em>
