Answer:
Answers A and B
Step-by-step explanation:
To divide fractions, you keep, change, flip. Keep the first fraction the same, 4/11. Change the division sign into a multiplication sign. Finally, find the reciprocal or "flip" the last fraction into 15/9. This makes the equation 4/11 x 15/9. Multiply across the top to get 60, and the bottom to get 99. This makes 60/99. Therefore, answer A is correct. Find some more equivelent fractions by multiplying or dividing the top and bottom by the same amount. In this proccess, you can find that answer B is also correct.

Step-by-step explanation:
For these problems I used the pythagorean theorem: and SOHCAHTOA
Sin =
Cos =
Tan =
11)
First find the length of the bottom side by using Cos
Then plug it into the formula for the pythagorean theorem to find the hypotenuse
12)
Find the length of the bottom side using Cos
Then plug it into the formula for the pythagorean theorem to find the hypotenuse
13)
Find the length of the other side by using Tan
Then plug it into the formula for the pythagorean theorem to find the hypotenuse
14)
(This is probably an easier way to do these problems)
Find the hypotenuse by using Cos ()
15)
Find the hypotenuse using Sin ()
16)
Find the hypotenuse using Cos ()
Answer:
100
Step-by-step explanation:
plug in y
-108.5=-2.61x+152.51
add like sides
-261.01=-2.61x
divide
100.00383=x
rounded=100
Answer:
The volume of the marble is 47 ml
The volume of the water is 100 ml
Step-by-step explanation:
we know that
The volume of the marble is equal to the change in water level
so
To find out the volume of the marble subtract 100 ml from 147 ml
The volume of the water no change
The volume of the water is 100 ml
