Answers

Answer 1
Answer: 4/26 can be simplified by 2. So, this is not the answer.
8/21 cannot be simplified. So, it is one of the answers.
6/19 cannot be simplified. So, it is one of the answers.
9/10 cannot be simplified. So, it is one of the answers.
10/22 can be simplified by 2. So, this is not the answer.

So, the fractions in simplest forms are 8/21, 6/19, and 9/10.

60% of what number is 150?

Answers

Answer:

90

Step-by-step explanation:

To solve this you must make a proportion of x/150 60/100. Then you need to find the relation between 100 and 150 which is x 1.5. Then apply the same thing to 60 which results in 90.

Answer: 250

You must set this up as a proportion

Remember the percent is always over 100

150/x=60/100

Then solve the proportion

60x=15000

Get the x by its self

15000/60 is 250

x=250

Brad and Wes are building a tree house. They cut a 12 1/2 foot piece of wood into 5 of the same length. how long is each piece of wood? show your work

Answers

Answer:

2(1)/(2) foot

Step-by-step explanation:

Brad and Wes cut a 12(1)/(2) foot piece of wood into 5 of the same length.

Let length of 1 piece be x

So, Length of 5 pieces = 5x

Total length of wood= 12(1)/(2)=(25)/(2)

So, 5x=(25)/(2)

x=(5)/(2)

x=2(1)/(2)

Hence Length of each piece is 2(1)/(2) foot
This is what I did
I divided 12.5/5=2.5 and each pieces of wood would be 2.5 FT.

Trina finds a car at a dealer for $6,100 The suggested retail price in the car price guide is $6,300. What is the difference between these two prices? Should Trina buy the car? Explain.

The solution for the given expression will be 10√6.

In mathematics, an expression is a combination of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. It represents a mathematical computation or relationship.

An expression can consist of constants, variables, and operators. Constants are fixed numerical values, like 5 or 3.14. Variables, on the other hand, are symbols that represent unknown or changing values, such as x or y.

To solve this problem you use the property:

√ab = (√a)(√b)

The expression will be solved as below,

√600 = (√6)(√100) = √6(10) = 10√6

r1² π : r2² π = 9 : 1.44
r1 : r 2 = 3 : 1.2
r2 = 1.2 · r1  / 3
r 2 = 0.4 · r1
If the two cylinders are similar than also: h 2 = 0.4 · h 2
V 1 = r1²   · π  · h1
V 2 = ( 0.4 r1)² π · 0.4 · h1 = 0.064 r1² · π · h1
V 2 ( small cylinder )= 0.064 · V 1 ( large cylinder )
