Answer with explanation:

The given expression is

=2^5 \times 2^4

→As, multiplication of real number follows Commutative property.

Which states that, if a and b are any two real numbers , then

a × b= b × a

The Expression equivalent to ,the above expression are

1. 2^4 \times 2^5\\\\ 2. 2^5=32 \text{and} 2^4=16, \text{So} 2^5 \times 2^4=32 \times 16=512

A visual-effects model maker for a movie draws a spaceship using a ratio of 1 : 24. The drawing of the spaceship is 22 inches lo
Kay [80]

Answer:

Length of spaceship in movie = 528

Step-by-step explanation:

Given that:

Drawing ratio of spaceship = 1 : 24

It means that 1 inch on drawing equals 24 inches in movie

Drawing of spaceship = 22 inches

Length of spaceship in movie = x

As the relationship is proportional,

1 : 24 :: 22 : x

Product of mean = Product of extreme

24*22 = x

x = 528

Hence,

Length of spaceship in movie = 528

schepotkina [342]
The answer would be 39/40.

1. Find the LCD of both of the fractions (LCD = 40)

2. Make the denominators the same as LCD (The LCD would be 40)

3. Simplify (24/40 + 15/40)

4. Join the denominators
(24 + 15/40)

5. Simplify (39/40)

In decimal form its 0.975.

Identify the percent of change as an increase or decrease. Then find the percent of change. Round to the nearest tenth of a perc
bazaltina [42]

I'll do the first two problems to get you started. All problems shown will use the same formula.

===========================================

Problem 4

The formula to use is

C = 100*(B-A)/A

where

A = old value

B = new value

C = percent change

In this case, A = 12 and B = 36, so

C = 100*(B-A)/A

C = 100*(36-12)/12

C = 100*(24/12)

C = 100*2

C = 200%

We have a 200% increase. It is an increase because the value of C is positive.

===========================================

Problem 5

Use the same formula as in the previous problem. This time,

A = 75 is the old value

B = 25 is the new value

C = 100*(B-A)/A

C = 100*(25-75)/75

C = 100*(-50/75)

C = 100*(-2/3)

C = -66.6667%

C = -66.7%

The value of C is negative, so we have a percent decrease of roughly 66.7%

The perimeter of a square picture frame is 5.4 inches . What is the length of one side? Write and equation and slove.
Anarel [89]

Answer:

s = 1.35 (See explanation!)

Step-by-step explanation:

To write an equation, you need to know that all four sides of a square are equal. Since each side is equal, it can be represented by the same variable or value. I'll use s for the variable:

Equation:

4s = 5.4

Note: the 4s is the total perimeter (4 * side)

Now, solve:

4s = 5.4

Divide by four to isolate the s:

4s/4 = 5.4/4

Finally:

s = 1.35
