So when the pool is filled by the two hoses together in 30 minutes, the larger hose itself fills 30/40 = 3/4 of the pool. That means in those 30 minutes the smaller hose fills 1/4 of the pool; and that means it would take the smaller hose 30*4 = 120 minutes to fill the pool alone.

Find the degree measure of 15.26 rad
kakasveta [241]

Answer:   " 874.33 °  " .

___________________________________

Step-by-step explanation:

15.26 rad * ( 180 degree / \pi  rad )  ;

          =  [ (15.26 * 180) / \pi ]  degrees ;

          =  [ ( 2746.8 ) / \pi  ] degrees.

          =  [ ( 2746.8) / 3.14) ]  degrees  ;

          =  874.3336 degrees;

          →  round to:  " 874.33 degrees ."

Please help me with this problem, please
Harman [31]

Answer:

sin(x) = 5/13

cos(y) = 5/12

Therefore, sin(x) = cos(y)

Step-by-step explanation:

Trig ratios:

sin(\theta)=\dfrac{O}{H}\\\\\\cos(\theta)=\dfrac{A}{H}\\\\\\tan(\theta)=\dfrac{O}{A}

where \theta is the angle, O is the measure of the side opposite the angle, A is the measure of the side adjacent to the angle and H is the hypotenuse, of a right triangle

We have been given the measures of the two legs, so we can find the measure of the hypotenuse by using Pythagoras' Theorem a^2+b^2=c^2

(where a and b are the legs and c is the hypotenuse of a right triangle)

\implies 5^2+12^2=c"\\\\\implies 169=c^2\\\\\implies c=\sqrt{169}\\\\ \implies c=13

Now we can use the trig ratios:

\implies sin(x)=\dfrac{5}{13}

\implies cos(y)=\dfrac{5}{13}

Therefore, sin(x) = cos(y)

Please help !! Use Pythagorean theorem :) and show your work if you can thanks :”) will give b
g100num [7]

Answer:

b=\sqrt{1575} ≈ 39.7ft

Step-by-step explanation:

The Pythagorean theorem:

a^{2}+ b^{2}= c^{2}

(a and b are the two shorter legs and c is the largest leg, which is also the opposite side of the right angle)

First, the value of a and c is given. So, we can go ahead and plug those value in and then solve for b.

45^{2}+ b^{2}= 60^{2}

2025+b^{2} =3600

To find b, we have to get it by itself. So we subtract 2025 from both sides then square root both sides. Resulting in:

b^{2} =1575

b=\sqrt{1575} ≈ 39.7ft

On a busy saturday a movie theater sells 700 children tickets and 300 adults tickets. They made $7200 in total. If each adult ti
natka813 [3]

Answer:

6 dollars per children ticket.

Step-by-step explanation:

Sorry if my explanation doesn't make much sense or you don't understand it.

700x + 300y = 7200

if, y = 10

700x + 300(10) = 7200

700x + 3000 = 7200

        - 3000 = -3000

700x             = 4200

700x/700   = 4200/700

x = 6
