Paul currently has $300 to spend on a data plan. He found a phone for $100 and a $50 a month charge.
zvonat [6]
Let x= months
So 50x is the total amount he pays after x months. You went to add 100 to this because there's a fixed cost of 100 for the phone
So you have the expression 100+50x which is the amount he pays after x months
Since he has a limit of 300,
100+50x < 300

Morgarella [4.7K]

Answer:

8.9 meters

Step-by-step explanation:

this seems like a problem where you can use the pythagorean theorem:

you know one of the two legs (6m) and  the hypotenuse (9m), you must find the other leg

a^2 + 6^2 = 9^2

a^2 + 36 = 81

a^2 = 45

a = \sqrt{45} or \sqrt{9} · \sqrt{5} which simplifies to be 3\sqrt{5} or approx. 8.9 meters

Find the value of z. round to the nearest hundredth
Svetradugi [14.3K]

ANSWER

C. 64.29

EXPLANATION

The bigger right triangle is similar to the smaller right triangle, therefore

\frac{30}{14}  =  \frac{z}{30}

Multiply both sides by 30;

30 \times  \frac{30}{14}  =  \frac{z}{30}  \times 30

Simplify

z =  \frac{900}{14}

z = 64.28571429

We correct to the nearest hundredthth to obtain,

z = 64.29

The correct choice is C.

4. Which expression is equivalent to sin(50)º?
jasenka [17]

Answer:

cos(400)

Step-by-step explanation:

Useful things:

Cofunction identity: sin(x)=cos(90-x)

Sine and cosine have period of 360 degrees.

So sin(50)=cos(40) by cofunction identity.

Since cosine has period of 360 degrees then cos(40)=cos(360+40).

That simplifies to cos(400).
