Tanzania [10]3 years ago
4 0

Answer:

Sonya pays a flat fee of $30 for her phone bill and pays $2 per gigabyte she uses per month. Put Sonya's bill as an equation with <em>d</em> being how many gigabytes she uses per month.

Step-by-step explanation:

We get the flat fee of $30 from "30 + 2d" and the $2 per gigabyte from "30 + 2d" and since we want to find out Sonya's total bill, that's where the + in "30 + 2d" comes from. We want the variable to be <em>d</em> therefore <em>d</em> is how many gigabytes she uses per month.

Resiprocal of (-3/7)^2!​
USPshnik [31]

Answer:

\frac{49}{9}

Step-by-step explanation:

Given

(\frac{-3}{7})^{2!}

Required

Determine the reciprocal

If a number is x, the reciprocal is: 1/x

So, the reciprocal of (\frac{-3}{7})^{2!} is:

\frac{1}{(\frac{-3}{7})^{2!}}

2! = 2*1 =2

So, we have:

\frac{1}{(\frac{-3}{7})^{2}}

\frac{1}{(\frac{-3^{2}}{7^{2}})}

Evaluate all exponents

\frac{1}{(\frac{9}{49})}

Take inverse of 9/49

\frac{49}{9}

Hence, the reciprocal of (\frac{-3}{7})^{2!} is \frac{49}{9}

(7 × 10-5) × 0.0007
Andrews [41]
First we do what’s in the parentheses.
7 • 10 - 5 = 70 - 5 = 65
Then we do exponents. We don’t have any so we skip this step.
Then we do multiplication and division.
65 • 0.0007 = 0.0455
We don’t have any addition or subtraction so we skip this step.
The solution is 0.0455.
