do you think making a table is the best way to find the total area of the rooms given in the example is there another problem solving strategy you think would work just as well or better describe the alternate method and why you think it works

Answers

Answer 1

Answer: Well,

First, we'd need to see what the problem is. If it's an illustration with all of the dimensions of the rooms labeled, you can just write the area inside each room and then make a list of the values. From there you can just add them up. So making a table is just a more formal way of organizing your data. The grids really do not offer much help in adding up the areas.

a rectangle with sides of length n+2 and n is compared to a square with sides of length n+1 are the two shapes equal in perimeter?

Answers

Both of the figures have the same perimeter (4n + 4) hence equal in perimeter,

What are the area and perimeter of a rectangle?

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

We know the perimeter of a rectangle is 2(length + width) and the perimeter of a square is 4×side.

Given, A rectangle with sides of length n+2 and n.

∴ Perimeter = 2((n + 2) + n)

= 2(2n + 2).

= 4n + 4.

Also given, A square with sides of length n + 1.

∴ Perimeter = 4(n + 1).

= 4n + 4.

So, yes the two shapes are equal in the perimeter.

Step-by-step explanation:

Determine the length, to 1 decimal place, of the arc that subtends an angle of 5.4 radians at the centre of a circle with radius 7 cm.

Answers

The length, to 1 decimal place, of the arc that subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm is 37.8 cm.

What is a circle?

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

It is given that:

The arc subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm.

As we know, the relationship between radius of the circle, central angle, and arc length is:

s = rθ

r = 7 cm

θ = 5.4 radians.

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

s = 7×5.4

s = 37.8 cm

Thus, the length, to 1 decimal place, of the arc that subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm is 37.8 cm.

If f(x) = 1 – x, which value is equivalent to |f(i)|?a. 0
b. 1
c. √2
d. √-1

Answers

If you would like to know which value is equivalent to |f(i)|, you can calculate this using the following steps:

f(x) = 1 - x
|f(i)| = |1 - i| = sqrt((1-i) * (1-i)^conjugate) = sqrt(2) = √2

The correct result would be c. √2.

Answer:

The answer is c

One card is randomly selected. a. Find the probability of selecting a number less than 81 or a number written in red.

Answers

less than 81 is from 80 to 1
that is 80 numbers
80/100=8/10=80%
80%
or a number writtten in red
50/100 are red
50% are red
it says or so it cannot be both
80%-50%=30%

answer is 30%
