Answer:

There are 4 Phones in the Family phone Plan.

Step-by-step explanation:

Given:

Monthly payment for each phone = \$22.91+\$20= \$42.91

Let the number of phones in the plan be x

cost of the family data plan per month = \$70

Total Monthly bill = \$241.64

Total Monthly bill = Monthly payment for each phone \timesnumber of phones in the plan + cost of the family data plan per month

∴ The equation becomes after substituting the value,

(42.91 \times x) + 70 = 241.64\\42.91x=241.64-70\\42.91x=171.64\\x= \frac{171.64}{42.91}\\x=4

∴There are 4 Phones in the Family phone Plan

Trey drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 12 hours. When Trey drove
USPshnik [31]

Question was Incomplete;Complete question is given below;

Trey drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 12 hours. When Trey drove home, there was no traffic and the trip only took 8 hours. If his average rate was 20miles per hour faster on the trip home, how far away does Trey live from the mountains?

Do not do any rounding.

Answer:

Trey lives 480 miles from the mountain.

Step-by-step explanation:

Given:

Time taken to drove the mountain =12 hours

Time taken to return back from mountain = 8 hours.

Let the speed at which he drove to mountain be denoted by 's'.

Speed on the trip to home = s+20

We need to find the distance Trey live from the mountains.

Solution:

Let the distance be denoted by 'd'.

Now we know that;

Distance is equal to speed times Time.

framing in equation form we get;

distance from home to mountain d=12s

Also distance from mountain to home d = (s+20)8=8s+160

Now distance is same for both the trips;

so we can say that;

12s=8s+160

Combining the like terms we get;

12s-8s=160\\\\4s=160

Dividing both side by 4 we get;

\frac{4s}{4}=\frac{160}{4}\\\\s=40\ mph

Speed while trip to mountain = 40 mph

Speed while trip to home = s+20=420+20=60\ mph

So Distance d=12s=12\times40 = 480\ miles

Hence Trey lives 480 miles from the mountain.

Prove that 1/sin^2A -1/tan^2A= 1
Vika [28.1K]

Answer:

Step-by-step explanation:

LHS =\dfrac{1}{Sin^{2} \ A }-\dfrac{1}{Tan^{2} \ A }\\\\\\ = \dfrac{1}{sin^{2} \ A}- \dfrac{1}{\dfrac{Sin^{2} \ A}{Cos^{2} \ A}}\\\\\\= \dfrac{1}{sin^{2} \ A } - \dfrac{Cos^{2} \ A}{Sin^{2} \ A}\\\\\\= \dfrac{1-Cos^{2} \ A}{Sin^{2} \ A}\\\\\\= \dfrac{Sin^{2} \ A}{Sin^{2} \ A}\\\\\\= 1 = \ RHS

Hint: 1 - Cos² A = Sin² A
