Answer:

tan(46) = 17/x

Step-by-step explanation:

The tangent of an angle is opposite over adjacent, so the tangent of 46 is 17/x, not x/17. Also, sin(46) = opposite/hypotenuse and cos(46) = adjacent/hypotenuse, but we aren’t given the hypotenuse. Therefore, the answer has to be tan(46) = 17/x.

scoray [572]

Step-by-step explanation:

cubing both sides (p+1)^3= (7)^3

=> p^3+1/p^3+ 3(p+1/p) = 343

=> p^3+ 1/p^3 + 3(7)= 343

=> p^3+1/p^3= 343-21

=> p^3+1/p^3= 322

Adam has 10 blocks numbered 1 through 10. Which describes the probability of randomly choosing a block that has an even number?

Licemer1 [7]

Answer:

$\dfrac{1}{2}$

Step-by-step explanation:

Given that:

10 number of blocks which have numbers from 1 through 10.

To find:

Probability of randomly choosing a block that has an even number.

Solution:

The given set of numbers is: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

There are a total of 5 Even numbers are {2, 4, 6, 8, 10}.

And There are a total of 5 Odd number are {1, 3, 5, 7, 9}.

Formula for probability of an event E can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

Here, Event E is randomly choosing an even number.

Number of favorable cases = 5

Total number of cases = 10

Therefore, the required probability is:

$P(E) = \dfrac{5}{10}\\\Rightarrow P(E) = \dfrac{1}{2}$

Natalie is paid $2 more per hour than Travis when Natalie works for 40 hours and Travis works for 35 hours they are $755 between

daser333 [38]

Answer:

Travis' per hour earnings = $135

Natalie's per hour earnings = $137

Step-by-step explanation:

Given:

Natalie is paid $2 more per hour than Travis

Natalie works for 40 hours

Travis works for 35 hours

The difference between their salaries for their work = $755

To find how much does each earn per hour.

Solution:

Let Travis earn in dollars per hour = $x$

So, for 35 hours of work, his earning in dollars will be = $35\times x = 35x$

Natalie will earn in dollars per hour = $x+2$

So, for 40 hours of work, her earning in dollars will be = $40\times (x+2) = 40(x+2)=40x+80$ [Using distribution]

The difference between the earnings can be given as:

⇒ $40x+80-35x$

Combining like terms

⇒ $5x+80$

The difference = $755

So, we have:

$5x+80=755$

Solving for $x$

Subtracting both sides by 80.

$5x+80-80=755-80$

$5x=675$

Dividing both sides by 5.

$\frac{5x}{5}=\frac{675}{5}$

$x=135$

So, Travis' per hour earnings = $135

Natalie's per hour earnings = $135+2=$ = $137
