rodikova [14]

Answer:

Number of monthly calls = 475

Step-by-step explanation:

Given:

Plan 1 = $30 per month unlimited calls

Plan 2 = $11 + $0.04(per call)

Find:

Number of monthly calls, plan 1 better than plan 2

Computation:

Plan 1 (Cost) < Plan 2 (Cost)

30 < 11 + 0.04(x)

19 < 0.04(x)

475 < (x)

Number of monthly calls = 475

Solve for k. k/2 +1/2=3

ikadub [295]

Answer:

$k = 5$

Step-by-step explanation:

Solve for $k$ :

$\frac{k}{2} + \frac{1}{2} = 3$

-Multiply both sides of the equation by the denominator $2$ :

$2 \times \frac{k}{2} + \frac{1}{2} = 3 \times 2$

$k + 1 = 6$

-Subtract both sides by $1$ :

$k + 1 - 1 = 6 - 1$

$k = 5$

So, the value of $k$ is $5$ .

Help !!!!<br> my math teacher wants me to answer this, and I have to give the answer in 10 minutes

mariarad [96]

45 degrees for x.
Do 180-160 = 20 (Since 180 is a straight line)
The 115, x, and 20 form another straight line, so take 180-20-115. You get 45.

Find the sum: 4 radical 3 + 11 radical 12

Ksenya-84 [330]

Answer:

$26\sqrt{3}$

Step-by-step explanation:

We want to find $4\sqrt{3} +11\sqrt{12}$ . $11\sqrt{12}$ can be written as $11\sqrt{4*3}=11*\sqrt{4} *\sqrt{3}=11*2*\sqrt{3}=22\sqrt{3}$ , so we can now write our original equation as: $4\sqrt{3}+22\sqrt{3}$ .

We can combine like terms: $4\sqrt{3}+22\sqrt{3}=26\sqrt{3}$

Hope this helps!
