Answer:

Step-by-step explanation:

PEMDAS is a set of rules which are followed while solving mathematical expressions. These rules start with Parentheses, and then operations are performed on the exponents or powers. Next, we perform operations on multiplication or division from left to right. Finally, operations on addition or subtraction are performed from left to right.

Answer:

PEMDAS is parenthesis, exponent, multiplication, division, addition, and subtraction

Step-by-step explanation:

before anything, you have to check for anything in a parenthesis. If nothing check for any exponents. If nothing do multiplication, and then do all division (of course wherever necessary). After that, you do all of the addition, then subtraction. everything in this order

The radius of the circle below intersects the unit circle at (Three-fifths, four-fifths). What is the approximate value of Theta

Fudgin [204]

The measured value of Theta is 53.1 degrees.

Given

The radius of the circle below intersects the unit circle at (3/5, 4/5).

<h3>What is tan theta?</h3>

The measure of the tan angle is defined as the ratio of perpendicular by the base.

The measure of the tan theta is;

$\rm Tan\theta=\dfrac{x}{y}$

Where the value of x is 3/5 and y is 4/5.

Substitute all the values in the formula

$\rm Tan\theta=\dfrac{x}{y}\\\\\rm Tan\theta=\dfrac{\dfrac{4}{5}}{\dfrac{3}{5}}\\\\\\Tan\theta = \dfrac{4}{5} \times \dfrac{5}{3}\\\\Tan \theta=\dfrac{4}{3}\\\\\theta=tan{-1}(\dfrac{4}{3})\\\\\theta=53. 1 \ degrees\\\\$

Hence, the measured value of Theta is 53.1 degrees.

A furniture store received an order for 8,367 tables they can fit 7 tables in the lower shipping box how many shipping boxes whe

-BARSIC- [3]

1195 boxes are needed to ship all the tables

<em><u>Solution:</u></em>

Given that, furniture store received an order for 8,367 tables

They can fit 7 tables in the lower shipping box

To find: Number of shipping boxes needed to ship all the tables

From given,

Total number of tables = 8367

Number of tables fit in one shipping box = 7

Thus, we can find the number of shipping boxes needed to ship all the tables by dividing total number of tables by number of tables fit in one shipping box

$\text{Number of shipping boxes needed } = \frac{\text{Total number of tables}}{\text{Number of table fit in one box}}$

Substituting the values we get,

$\text{Number of shipping boxes needed } = \frac{8367}{7}=1195.28 \approx 1195$

Thus 1195 boxes are needed to ship all the tables
