3. Consider The Following Expressions. EVALUATE Each Expression ANDEXPLAIN WHY They Have Different Answers.2

Answers

Answer 1
the first one = 12 and the second one = 18.
the reason why they have different answers is because of PEMDAS.

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

For the first equation we gave to multiply the exponent (2) to the number (3) because that’s the order of PEMDAS. So, 3x2=6 then + 6=12.

For the second equation there are parentheses, which means we solve the equation inside the parentheses first because of PEMDAS. So, 6+3=9 then x 2 =18.

They have different answers because they are ordered in different ways . PEMDAS controls the order we solve equations in.


Hope this helped:)))

Answer: 69 cents

Step-by-step explanation:

First you find the area of the circle (A = radius squared * pi) then you multiple the are by 5.5. That will give you the total volume of the can then to find what profit from the can you would multiple the volume by .01 to get .69.

Answer:

Rounded to nearest hundred

Here we will tell you what 69 is rounded to the nearest hundred and also show you what rules we used to get to the answer.

Remember, we did not necessarily round up or down, but to the hundred that is nearest to 69.

First, 69 rounded to the nearest hundred is:

100

When rounding to the nearest hundred, like we did with 69 above, we use the following rules:

A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

SO IT IS 100

But if it was nearest tenth that would be 70

Answer:

F. A reflection over the x-axis and a horizontal stretch

Step-by-step explanation:

Using Desmos, a well-known graphing-calculator website, you can input the two equations. You can see that the h(x)= -(x/4)^2 equation does in-fact reflect over the x-axis and is wider than x^2, meaning that it has a horizontal stretch.

A. Marcia is running home.
B. Marcia is walking home.
C. Marcia is turning a corner.
D. Marcia is stopping to rest.

Answers

Possibly C sorry if it’s wrong

Answer:

D. Marcia is stopping to rest

Step-by-step explanation:

At intervals B to C, we can see that Marcia's distance from home has not risen nor dropped. We can safely assume that she is not moving. Of course, time has not stopped, because the line continues to move from left to right. So, Marcia is likely stopping to rest for a moment.

What is the formula for the volume of a trapezoidal prism?

Answers

Answer:

Ok so basically, the formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.

Answers

Answer:

Let me figure it out rq hold on

how to find the surface area:

The surface area of the triangular prism is the sum total of the areas of its bases and its lateral faces,

736 square feet

We have 2 triangles to add and 3 rectangles.
Area of a rectangle is length x width.
Area of a triangle is 1/2 x base x height.

The top 2 rectangular sides are 20 x 10 = 200 each = 400 total.
The bottom rectangle is 20 x 12 = 240
The triangles are each 1/2 x 12 x 8 = 48, and there are 2 triangles, = 96


Add them all up: 400 + 240 + 96 = 736 square feet
