when does order matter when writing algebraic expression

Answers

Answer 1
Think of PEMDAS. Solve in this order. Parentheses, Exponent, Multiply, Divide, Add, Subtract. Solving in this order will get you to the right answer. If you try to just solve from left to right, you may get it wrong if it is not solved in that order.

Drew has two cats. One cat weighs 17 pounds, and the other one weighs 1212 pounds. Audrey’s dog weighs 33 pounds.
What is the difference in ounces between Audrey’s dog and the combined weights of Drew’s cats?
Enter your answer in the box.

Answers

Answer:

48 ounces

Step-by-step explanation:

Answer:

64 ounces.

Step-by-step explanation:

combined weigh = weight of cat 1 + weight of cat 2

combined weigh = 17 + 12 = 29 pounds

The difference in weight of the Dog's weigh by the combined cat's weigh is the subtraction between the two, so we have:

Difference in weigh = 33 - 29 = 4 pounds

We now have to convert it to ounces, since 1 pound contains 16 ounces we can multiply the value of the weigh in pounds by 16 to obtain the final value:

Difference in weigh = (4 pounds)* 16 = 64 ounces

The population P of bacteria in a culture after t minutes is given by the equation p=p0 (1.14)^t where P0 is the initail population. If the number of the bacteria starts at 400, how long will it take for he population to incfrease to 2000

Answers

Answer:

The time taken is 4.79 minutes.

Step-by-step explanation:

[tex]P = Po(1.4)^{t}[/tex]

initial Population, Po = 400

Final population, P = 2000

Let the time is t.

[tex]2000 = 400(1.4)^{t} \\5 = (1.4)^t\\log 5 = t log 1.4\\0.6989 = 0.146 t \\t = 4.79 minutes[/tex]

Answers

Answer:

-3x^2+16x+64

Step-by-step explanation:

First, you need to find the area of both areas (the total area and the area of the unshaded part). Let's find the total area.

(x+8)(x+8)=x^2+16x+64

The total area is x^2+16x+64

(2x)(2x)=4x^2

The area of the unshaded part is 4x^2

Now we have to subtract to find the area of the shaded part.

x^2+16x+64-4x^2

-3x^2+16x+64

That is the answer

Jessie has rewritten the quadratic equation x2-32x +54 -0 in the form (-p) = 202. What is the value of p in the rewritten equation?

Answers

Given:

The quadratic equation is:

[tex]x^2-32x+54=0[/tex]

It can be written as [tex]-p=202[/tex].

To find:

The value of p in the rewritten equation.

Solution:

We have,

[tex]x^2-32x+54=0[/tex]

Isolate the constant term.

We need to make 202 on the right side. So, add 256 on both sides.

[tex]x^2-32x+256=-54+256[/tex]

[tex]x^2-32x+256=202[/tex]

[tex]-(-x^2+32x-256)=202[/tex]

Let [tex]-x^2+32x-256=p[/tex], then

[tex]-p=202[/tex]

Therefore, the value of p is [tex]-x^2+32x-256[/tex].

The given equation can be written as:

[tex]54=-x^2+32x[/tex]

Adding 148 on both sides, we get

[tex]54+148=-x^2+32x+148[/tex]

[tex]202=-(x^2-32x-148)[/tex]

Let [tex]x^2-32x-148=p[/tex], then

[tex]202=-p[/tex]

Therefore, the another possible value of p is [tex]x^2-32x-148[/tex].

The length of a rectangle is 5 inches more than its width. The area of the rectangle
is 150 centimeters. Find the dimensions of the rectangle.

Answers

it's good to write it out

length = 5 + width

area = 150

width = x

length = 5 + x

area = length * width

so

(5 + x) (x) = 150

5x + x^2 = 150

x^2 + 5x - 150 = 0

following you have to guess what 2 numbers when multiplied male 150 and when added make 5

and they are 15 and 10

(x +15) (x-10)

x = -15

x = 10

Step-by-step explanation:

The most important thing to remember is: SOH CAH TOA

sin(x) = opposite/hypotenuse

cos(x) = adjacent/hypotenuse

tan(x) = opposite/adjacent

So in #1:

We have the angle and hypotenuse and need to solve for the side opposite of the angle. This smells like a sine question.

sin(42)=x/25

this means that x=25sin(42). Plug that into the calculator and get: 16.73.

(Make sure you are in degrees mode)

For #2:

We are given the angle, the opposite side, and have to solve for the adjacent side. Looks like we need the tangent.

tan(75)=12/x

This means that x=12/tan(75). Calculator says: 3.22

For #3:

We have the angle, adjacent, and have to solve for the hypotenuse. This would be a cosine.

cos(36)=19/x

Solve for x: x=19/cos(36). Calculator says: 23.49

For #4:

We have the angle, adjacent side, and need the opposite side. This is another tangent problem.

tan(53)= x/7

Solving for x: x=7tan(53). Calculator says: 9.29

Using the Exxon data as an example pretend Pennys Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares what percent of Penny's Picklesdo you own

Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have  [tex]2\[/tex]  percent of Penny's Pickles.

What is percentage?

Percentage a is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, [tex]\%[/tex].

Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]

We have,

Total shares of Penny's Pickles [tex]=10,000[/tex]

You owned shares   [tex]= 200[/tex]

So,

Using above formula,

Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]

Percentage of shares I owned [tex]=\frac{200}{10000} * 100[/tex]

                                                    [tex]= 2 \%[/tex]

So, the shares you owned are [tex]2\ \%[/tex] of total share of the Penny's Pickles.

Hence, we can say that Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have  [tex]2\[/tex]  percent of Penny's Pickles.
