What is 3/4 of 40= fractions

Answers

Answer 1
Answer: Answer:
30

Explanation:
To get a fraction of a number, we simply multiply this fraction by the given number

In the given we want to compute 
(3)/(4) of 40.

This can be computed as follows:
(3)/(4) of 40

(3)/(4) * 40

(3*40)/(4)

(120)/(4)

= 30

Hope this helps :)
Answer 2
Answer:

The three-fourth of the number 40 will be 30.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The expression is given as,

⇒ 3/4 times 40

Simplify the expression, then we have

⇒ 3/4 times 40

⇒ 3/4 x 40

⇒ 3 x 10

⇒ 30

I don't get this problem. Lila decided to make kore baked goods for the bake sale. She used 1 / 8 lb less flour to make bread than to make cookies. She used 1/4 lb more flour to make cookies than to make brownies. If she used 1/2 lb of flour to make bread , how much flour did she use to make the brownies?

Answers

Start by taking the information we know, and write equations to represent the realationships:

1) "1/8 lbs less flour to make bread than to make cookies"         
     b=c-(1)/(8)

2) "1/4 lb more flour to make cookies than to make brownies:
     c=w+(1)/(4)

3) "she used 1/2 lb of flour ro make bread"
    b = (1)/(2)

From here you can solve for w using back substitution. 

Why do whole numbers raised to an exponent get greater well fractions raised to an exponent get smaller

Answers

Because when you raise an exponent on a fraction, it is basically dividing into itself.  Imagine 1/3 multiplied my 3 (Ans is 1), the fractions aren't whole numbers so when they multiply into another number, it uses division

Ho do you get the Surface Area of this shape?

Answers

This solid object contains 8 sides.

The side that is facing you has a surface area:

64f{ t }^( 2 )+84f{ t }^( 2 )=148f{ t }^( 2 )

The side exactly opposite this one has the same surface area - 2 sides with this surface area in total.

The bottom side has a surface area:

84f{ t }^( 2 )

The side to your right has a surface area:

84f{ t }^( 2 )

The side to your left has a surface area:

48f{ t }^( 2 )

The side to your top left has a surface area:

48f{ t }^( 2 )

The side beside the side to the top left has a surface area:

36f{ t }^( 2 )

The side at the very top has a surface area:

36f{ t }^( 2 )

Combined, the surface area is:

S=2\cdot 148f{ t }^( 2 )+2\cdot 84f{ t }^( 2 )+2\cdot 48f{ t }^( 2 )+2\cdot 36f{ t }^( 2 )

\n \n =296f{ t }^( 2 )+168f{ t }^( 2 )+96f{ t }^( 2 )+72f{ t }^( 2 )\n \n =632f{ t }^( 2 )

Therefore the answer is: C

Suppose MyBook sent out 2100 surveys. Which of these numbers of surveys being returned would prevent non response bias?

Answers

To prevent non-response bias, it is generally recommended to aim for a response rate of at least 60% or higher, so MyBook should ideally have at least 1260 surveys returned.

The level of survey response required to prevent non-response bias depends on various factors such as the target population, the survey's objective, and the overall response rate. In general, a higher response rate is preferred to minimize non-response bias. A common rule of thumb is to aim for a response rate of at least 60% or higher.

If a substantial number of surveys are not returned, the results may not accurately represent the opinions and characteristics of the entire target population. For instance, if only 30% of the surveys are returned, it leaves a large proportion of the population unaccounted for, potentially biasing the results towards those who responded.

However, it's essential to consider the context of the survey and the population being surveyed. In some cases, achieving very high response rates might be impractical or unnecessary, especially when dealing with large populations or sensitive topics.
