Nan rode the roller coaster 8 times which was twice as many times as she rode the ferris wheel

Answers

I'm assuming that you're looking for the number of times Nan rode the Ferris Wheel. The question says that 8 times is twice as many times as the Ferris Wheel, so you would divide 8 by 2 to get 4. Nan rode the Ferris Wheel 4 times.

Find the percent of change in altitude if a weather balloon moves from 50 ft to 95 ft. Describe the percent of change as an increase or decrease. Round to the nearest tenth if necessary.A. 90%; increase

B. 55.9%; decrease

C. 90%; decrease

D. 76.5%; increase

Answers

The change of the weather balloon would be 90% increase. to get the percentage of change we have to subtract 50 ft to 95 ft, it will then give us the 45 ft change. Then we have to divide 45 ft by 50 ft times 100, it will give us 90%. Then since the change and percentage of change is positive then the change could be describe as increasing.

Howdy! Id love to have these questions answered asap! Thank you for the help! 1) Which angle is not coterminal to 120 degrees?
A. 840
B. -180
C. 480

2) Use the unit circle and the reference angle to determine which of the following trigonometric values is correct when theta = -90
A. Cos theta = undefined
B. Sin theta = -1
C. Tan = 0

Answers

Answer:

1. B.

2. B.

Step-by-step explanation:

Trigonometry

1) Coterminal angles can be found by adding or subtracting 360° (or 2\pi radians) to a given angle. If we have 120°, adding 360° gives 480°, adding again 360° gives 840°. There is no way to get -180°, so this option is not a coterminal angle to 120°

A. $Cos (-90^o)=0$ , and not undefined

B. $Sin (-90^o)=-1$ . This is correct

C. $Tan (-90^o)$ is undefined, not zero

Thus the only correct option is B.
