Given that

time required to filled 1/7 of pool = 1/10

so time required to fill  1 pool = 1/10 ÷ 1/7 = 1/10 × 7 = 7/10 hrs

So 0.7 hrs will require to fill the pool at given rate

Answer:

It takes   \frac{7}{10}  of an hour to fill the pool

Step-by-step explanation:

Let x be the number of hours taken to fill the pool.

Using proportion;

1/7 pool=   1/10 hour

1    pool   =   x

cross-multiply

1/7     x   =  1/10

\frac{x}{7}   =   \frac{1}{10}

cross- multiply

10x = 7

Divide both-side of the equation by 10

\frac{10x}{10}      =    \frac{7}{10}

(On the left-hand side of the equation 10 at the numerator will cancel-out 10 at the denominaor while at the right-hand side of the equation 7 will be divided by 10)

x =  \frac{7}{10}  of an hour

It takes   \frac{7}{10}  of an hour to fill the pool

Bill booked a ride to the airport. If it rains, the traffic will be bad and the probability that he will miss his flight is 0.06
kvasek [131]

Answer:0.614

Step-by-step explanation:

Given

Probability he will miss flight if it rains=0.06

Probability he will miss flight it does not rain=0.01

Given the probability of rain=0.21

Therefore Probability that it will not rain=1-0.21=0.79

Probability that he will miss the flight =0.21\times 0.06+0.79\times 0.01=0.0205

P(actual raining and he missed the flight| he miss the flight)=\frac{0.21\times 0.06}{0.21\times 0.06+0.79\times 0.01}

=\frac{0.0126}{0.0205}=0.614

What conic section degenerates into a line?
andrew11 [14]
<h3>Answer: A) parabola</h3>

Some degenerate parabola cases form a single straight line, while other cases form one pair of parallel lines.

A degenerate hyperbola forms two lines that intersect at the vertex of the cone. We can rule out choice B.

A degenerate circle is a single point, so we can rule out choice C.

A degenerate ellipse is also a single point. Any circle is an ellipse (but not the other way around). We can rule out choice D.

A school concert has students tickets for $7 and nonstudents tickets for $12. If the school made $1973 selling 214 tickets? How
bearhunter [10]

Answer:

119 student tickets and 95 non-student tickets

Step-by-step explanation:

I did a trial-and-error solution.

I started with 107 students and 107 non-students:

(107*$7)+(107*$12) = $2033

It was too high, which tells us that there should be more who paid for the cheaper price.

I ended up with 119 and 95:

(119*$7)+(95*$12) = $1973
