Help, please in this problem

Mathematics
1 answer:
Nikolay [14]3 years ago

Answer:

x=9.768

y=6.972

Step-by-step explanation:

For this problem we have to use the trig relationships of cos and sin to figure out the lengths. Cos is equal to adjacent/hypotenuse so we can set it as x/r=.814 and since r is equal to 12 we can do 12 times .814 to get x.

We do a similar process for sin but sin is equal to opposite/hypotenuse so we can set up the equation y/r=.581 and we simply multiply both sides by 12 to get 12*.581 to get y.

Also for future reference adjacent and hypotenuse are based on the angle at use, since ∅ is on the bottom left x is the adjacent side and y is the opposite side.

Step2247 [10]

Answer:

Volume = 9900 ft2

Step-by-step explanation:

To find the volume of the pool, we can use the base as the trapezoid, and then we need to calculate the base area and multiply by the height.

The trapezoid has a bigger base of 8 and a smaller base of 3, with a height of 60, so the area is:

Area = (8+3)*60/2 = 330 ft2

Now, to find the volume, we just need to multiply the base area by the height of 30 feet:

Volume = Area * Height = 330 * 30 = 9900 ft2

Shawn is coasting down a 500 cm long ramp on his inline skates. The wheels on his inline skates are 32 cm in circumference. How
damaskus [11]

Answer:

16 rotations.  

Step-by-step explanation:

We have been given that Shawn is coasting down a 500 cm long ramp on his inline skates. The wheels on his inline skates are 32 cm in circumference.

To find the number of rotations we will divide length of ramp by 32 as distance covered by wheels in one rotation will be equal to 32 cm.

\text{Number of rotations}=\frac{\text{Total distance}}{\text{Circumference of wheel}}

\text{Number of rotations}=\frac{500}{32}

\text{Number of rotations}=15.625\approx 16

Therefore, each wheel must make 16 rotations while Shawn is coasting down the ramp.

-1 - (-16) <br> plz find the absolute value of this!
djyliett [7]

Answer:

16

Step-by-step explanation:

the absolute value is always it's distance away from 0 on a number like so -16 is 16 numbers away from 0 so it's 16 the that's the absolute number of digits -16 is away from 0
