Yes because 3*5 = 15

Solve for p 8/9 12/p

siniylev [52]

8/9 = 12/p multiply by p on both sides
(8/9)p = 12 distribute p
8p/9 = 12 multiply by 9 on both sides
8p = 108 divide by 8
p = 108/8 simplify
p = 27/2

Help! Given that tanθ=-1, what is the value of secθ, for 3π/2<θ<2π?

user100 [1]

Answer: Choice B) $\sqrt{2}$

Work Shown:

$\sec^2(\theta) = \tan^2(\theta) + 1\\\\\sec^2(\theta) = (\tan(\theta))^2 + 1\\\\\sec^2(\theta) = (-1)^2 + 1\\\\\sec^2(\theta) = 2\\\\\sec(\theta) = \sqrt{2}\\\\$

Note: secant is positive in quadrant Q4, when theta is between 3pi/2 radians and 2pi radians (270 degrees and 360 degrees). So that's why we don't consider the minus form of the plus minus.

My am never friends have 3/4 and one nickel to spend if Maia and her friends share the money equally how much for each person ge

EleoNora [17]

Answer:

Each person get = 20 cents

Step-by-step explanation:

Given - Maya and three friends have three quarters and one nickel to spend.

To find - If Maya and her friends share the money equally how much will each person get ?

Proof -

We know that

1 nickel = 5 cents

1 quarter = 25 cents

As they spent, 3 quarters and one nickel

So,

Total money spent = 3(25) + 5 = 75 + 5 = 80 cents

⇒Total money spent = 80 cents

Now,

Total people = 4 (Maya and three friends )

Now,

Given that, They share the money equally

So,

Each person get = $\frac{80}{4}$ = 20 cents
