Lalo has 1,500 minutes per month on his cell phone plan. How many more minutes can he use if he has already talked for 785 minut

Ket [755]

Answer:

715 minutes

Step-by-step explanation:

we know that

To find out how many more minutes he can use, subtract the number of minutes he has already talked from the number of minutes of his plan

Let

x -----> the number of minutes of his plan

y -----> he number of minutes he has already talked

$x-y$

we have

$x=1,500\ min\\y=785\ min$

substitute

$1,500-785=715\ min$

The rule in this pattern is add 3. Write the next 4 terms of the pattern. What do you observe about the terms in the pattern? Ex

Afina-wow [57]

If the rule for this pattern is add 3, you would take term 1 which had 5 dots then add 3, that makes term 2 have 8 dots, than add 3 that means term 3 has 11 dots, term four would have 14, and each term after that would have 3 more

If sin a= 12/13 and tan B 8/15 and angles a and b are in qundrant 1 find the value of tan (a+b)

natali 33 [55]

Answer:

The value of Tan (a + b) is $\frac{-220}{21}$ .

Step-by-step explanation:

Given as :

Tan b = $\frac{8}{15}$

Sin a = $\frac{12}{13}$

∵Sin Ф = $\dfrac{\textrm perpendicular}{\textrm Hypotenuse}$

So, $\dfrac{\textrm perpendicular}{\textrm Hypotenuse}$ = $\frac{12}{13}$

Now, Base² = Hypotenuse² - Perpendicular²

Or, Base² = 13² - 12²

Or, Base² = 169 - 144

Or, Base² = 25

∴ Base = $\sqrt{25}$ = 5

And Tan Ф = $\dfrac{\textrm perpendicular}{\textrm Base}$

Or, Tan a = $\frac{12}{5}$

Now, Tan (a + b) = $\dfrac{Tan a + Tan b}{1- Tan a Tanb}$

Or, Tan (a + b) = $\frac{\frac{12}{5}+\frac{8}{5}}{1-(\frac{12}{5}\times \frac{8}{15})}$

or, Tan (a + b) = $\frac{\frac{36+8}{15}}{\frac{75-96}{75}}$

or, Tan (a + b) = $\frac{\frac{44}{15}}{\frac{-21}{75}}$

Or, Tan (a + b) = $\frac{-220}{21}$

Hence The value of Tan (a + b) is $\frac{-220}{21}$ . Answer

What is the sales tax of a $15.95 video game if the tax rate is 7%

harina [27]

Answer:

$17.07

Step-by-step explanation:

Step 1: Find the percent of the price

Convert 7% to fraction

$= \frac{7}{100}\\\\=\frac{7}{100}\times \:15.95$

Multiply

$=\frac{7\times \:15.95}{100}$

Multiply the factors

$7\times \:15.95=111.65\\\\=\frac{111.65}{100}$

Divide

$\frac{111.65}{100}=1.1165\\\\=1.1165$

Step 2: Add the percent off to the original price

$15.95 + 1.1165\\\\= 17.0665$

Therefore, the total cost including tax in the nearest cent is 17.07 dollars
