Divide 7 1/2 by 9

Write 7 1/2 as 15/2 divided by 9

Which goes to 15/2 (times) • 9/1

Cross simplify the 15 an 9 by 3

Your equation is now 5/2 • (times) 1/9

Which equals 5/6

ANSWER~ Monica can read 5/6 of a page a minute.

the answer is the number of pages divided by the number of minutes.

7.5/9=0.833333, so she reads on average 0.83 pages per minute

babymother [125]

Answer:

(B)1005 feet

Step-by-step explanation:

In the attached diagram

$\angle y =82^\circ\\\angle x =60^\circ$

|AG|=1400 feet

Distance from point C to point G=|CG|

Using Trigonometry in Triangle ACG

$\tan 60^\circ=\dfrac{1400}{CG}\\ CG=\dfrac{1400}{\tan 60^\circ}\\\approx 808$ feet$

Using Trigonometry in Triangle BCG'

$\tan 82^\circ=\dfrac{1400}{CG'}\\ CG'=\dfrac{1400}{\tan 82^\circ}\\\approx 197$ feet$

Therefore, the distance from balloon B from balloon A

=CG+CG'

=808+197

=1005 feet

rewona [7]

Answer:

15.6%

Step-by-step explanation:

Since each day there is a 6% chance that Lisa smiles at him then that means that each day there is a 94% chance that Lisa does not smile at him. To find the probability of Milhouse going longer than a month (30 days) without a smile from Lisa we need to multiply this percentage in decimal form for every day of the month. This can be solved easily by putting 94% to the 30th power which would be the same, but first, we need to turn it into a decimal...

94% / 100 = 0.94

$0.94^{30}$ = 0.156

Now we can turn this decimal into a percentage by multiplying by 100

0.156 * 100 = 15.6%

Finally, we can see that the probability that Milhouse goes longer than a month without a smile from Lisa is 15.6%

Ganezh [65]

Answer:

The value of P(z<1.00)=0.8413

Step-by-step explanation:

Using a standard normal table, the area under the standard normal curve below the given value of z=1 is:

z .00 .01

0.9 0.81594 0.81859

1.0 0.84134 0.84375

1.1 0.86433 0.86650

P(z<1.00)=0.84134

Rounded to 4 decimal paces

P(z<1.00)=0.8413
