What’s pemdas and how do we use it ?

Answers

Answer:

pemdas is an order of operation

Step-by-step explanation:

PEMDAS STANDS FOR parentheis, exponents, multiplication, division, addition, and subtraction. it is the order of how you should solve multi step equations EXAMPLE: 1+2x2 FIRST you have to multiply the 2x2 because multiplication comes first in PEMDAS, then you do the addition so 2x2=4+1=5

PEMDAS is the order that you solve a problem.

PEMDAS stands for:

Parenthesis

Exponents

Multiplication and Division

Addition and Subtraction

If you have an equation or expression that you need to solve, you solve it in this order. You do the parenthesis first, then you solve the exponents, then you do the multiplication and division from left to right, and last you do addition and subtraction from left to right.

In the equation

2 + 3 * 5,

first you would do 3 * 5 because multiplication is before addition.

2 + 15

Then you would do the addition to get the answer:

17.

A company sells three types of gift baskets. The basic basket has two movie passes and one package of microwave popcorn, and costs $15.50. The medium basket has two movie passes, two packages of microwave popcorn, and one DVD, and costs $37. The super basket has four movie passes, three packages of microwave popcorn, and two DVDs, and costs $72.50.



Create a system of equations and solve using matrices to find the price of each basket item.

Answers

The price of each movie is $7, the price of each microwave popcorn is $1.50 and the price of each DVD is $20.

Let x represent the cost of each movie, y represent the cost each microwave and z represent the cost of each DVD.

For the basic:

2x + y = 15.50    (1)

For medium:

2x + 2y + z = 37    (2)

For super:

4x + 3y + 2z = 72.50  (3)

[tex]\left[\begin{array}{ccc}2&1&0\\2&2&1\\4&3&2\end{array}\right] \left[\begin{array}{c}x&y&z\end{array}\right] = \left[\begin{array}{c}15.5&37&72.5\end{array}\right] \\\\\\ \left[\begin{array}{c}x&y&z\end{array}\right] =\left[\begin{array}{ccc}2&1&0\\2&2&1\\4&3&2\end{array}\right]^{-1}\left[\begin{array}{c}15.5&37&72.5\end{array}\right]\\\\\\ \left[\begin{array}{c}x&y&z\end{array}\right] = \left[\begin{array}{c}7&1.5&20\end{array}\right] =[/tex]

The price of each movie is $7, the price of each microwave popcorn is $1.50 and the price of each DVD is $20.

A helicopter floats 120m above a helipad, a dog is 85m from the helipad, if the dog could fly, how far would it have to fly to get to helicopter?

Answers

If the dog could fly, it would need to fly 147 meters to catch the helicopter

This is a rather easy and straightforward question. We are going to solve it using Pythagoras theorem. We can interpret the question to be in a triangle where the height of the helicopter above the helipad and away from the dog is the right angle. This also means that the distance needed, between the dog and the helicopter is the hypotenuse.

Using pythagoras theorem, we have

120² + 85² = c²

c² = 14400 + 7225

c² = 21625

c = [tex]\sqrt{21625}[/tex]

c = ±147 meters.

Since distance cant be in the negative, our answer is 147 m

LA Fitness Club charges an initial fee of $25
plus a monthly fee of $15. 24 hours fitness club
charges $45 initially plus $10 per month. In
how many months will the clubs cost the
same? How much is the cost?

Answers

Let’s make a system of equations
LA fitness club: y=15x+25
24 hours fitness club: y=10x+45
Then we substitute y to make them equal
15x+25=10x+45
5x=20
x=4
So therefore, 4 months and they will be equal

Option 3 : 19m, 34m, 15m

Step-by-step explanation:

First we must know this,

The length of the third side of a triangle must be less than than the sum of the lengths of any two sides of a triangle.

So, Now let us check one by one :

Option 1 : 5m, 6m, 8m

5 + 6 > 86 + 8 > 55 + 8 > 6

So, 5m, 6m, 8m can form a triangle .

Option 2 : 10m, 10, 2m

2 + 10 > 1010 + 10 > 210 + 2 > 10

So, 10m, 10m, 2m can form a triangle .

Option 3 : 19m, 34m, 15m

19 + 15 ≯ 34

So, 19m, 34m, 15m cannot form a triangle .

Option 4 : 3m, 16m, 14m

3 + 14 > 1616 + 14 > 316 + 3 > 14

So, 3m, 16m, 14m can form a triangle .
