So 1/5 pound for 7 days
1/5 ÷ 7
rewrite the 7 as a fraction of 7/1
1/5 ÷ 7/1
keep the first fraction, change the division sign to multiplication, flip the second fraction
1/5 * 1/7
multiply across
(1 * 1) / ( 5 * 7)
1/35

She should eat 1/35 of a pound each day to make her 1/5 of a pound last a week, or seven days.

Hope this helps

Well, she should eat then 1/5 ÷ 7, that way she'd split the 1/5 lb in 7 equal pieces, one for each day

$\bf \cfrac{1}{5}\div 7\implies \cfrac{1}{5}\div \cfrac{7}{1}\implies \cfrac{1}{5}\cdot \cfrac{1}{7}\implies \cfrac{1}{35}$

Answer:

The equation $35x+93\frac{3}{4} =190$ gives average time spent on 35 rehearsals.

Step-by-step explanation:

We are supposed to find that what question does the equation $35x+93\frac{3}{4} =190$ finds answer of.

We can see that 35x represents time spent on 35 rehearsals and $93\frac{3}{4}$ is time spent on other responsibilities related to play. The sum of these times equals to total time spent on preparing the play.

Now let us solve our equation step by step.

$35x+\frac{375}{4} =190$

After subtracting $93\frac{3}{4}$ hours from 190 hours we will get time spent on 35 rehearsals.

$35x =190-\frac{375}{4}$

$35x =\frac{760-375}{4}$

$35x =\frac{385}{4}$

Time spent on 35 rehearsals is 96.25 hours and we are told that each rehearsal took different amount of time. Dividing 96.25 by 35 we will get average time spent on each rehearsal.

$x =\frac{96.25}{35}=2.75$

Therefore, equation $35x+93\frac{3}{4} =190$ finds average time spent on 35 rehearsals.

A certain star is 2.4 x 102 light years from the Earth. One light year is about 5.9 x 1012 miles. How far

Studentka2010 [4]

Answer:

2.5 x $10^{15}$ miles

Step-by-step explanation:

We are given that 1 light year ≈ 5.9 x $10^{12}$ miles so:

4.3 x 10² light year · 5.9 x $10^{12}$ miles
1 light year

Multiply 4.3 an 5.9 and round to 2 significant digits then add the exponents:

≈25 x $10^{14}$

This is not the scientific notation since the number is not between 0 and 10 so we move the decimal point by 1 place to the left. We then add 1 to the exponent to obtain the final answer:

≈ 2.5 x $10^{15}$ miles
