To round 7,458 to the nearest hundred, which digit do you look at?

Answers

Step-by-step explanation:

We have the number 7458

In order to round a number to the nearest hundred, you need to look at the place before that one. In the case of the nearest hundred, you need to look at the tens place.

As there is a 5 in the tens place, you would round this number up

Therefore, the rounded number would be 7500

5 because you have 7,000 400 50 8 and you go ten to hundred in this case

You used 1/8 of a bag of dirt to fill 1/12 of your garden box. How many bags of dirt are needed to fill one garden

Answers

Answer:

1 1/2 bags

Step-by-step explanation:

given 1/8 of a bag will fill up 1/12 of a garden box, i.e.

1/8 bag ------> fills 1/12 box   (rearrange this)

1/12 box ----> requires 1/8 bag

to find how many bags it takes to fill 1 box, we simply multiply both sides of this equation by 12 to get the unit rate of fill

( 1/12 ) x 12 box -----> requires (1/8) x 12  bags

1 box ------> requires 12/8 = 3/2 = 1 1/2 bags  (answer)

I’m pretty sure it’s 1 1/2 bags

Jacinta says that the product of a rational number and an irrational number is always irrational. Explain her error.

Answers

if u multiply an irrational number by 0 the result will be 0 which is a rational number. Except this case, other times will result with irrationals.

Jacinta says that the product of a rational number and an irrational number is always irrational her claim is wrong.

What is a rational number?

A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.

Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.

Given that Jacinta says that the product of a rational number and an irrational number is always irrational.

Her statement is incorrect because if 0 a rational number is multiplied with the π which is irrational then the result will be 0 which is rational.

Therefore, Jacinta's claim is wrong.

Emma and Ed walk into a room containing 30 assembled Tworks and enough pieces to assemble 100 more Tworks. A Twork takes eight minutes to assemble and 10 minutes to disassemble. If Emma starts assembling Tworks as Ed begins disassembling the ones that were already made, and they both continue to work until there are exactly 35 assembled Tworks in the room (and no partially assembled or disassembled Tworks), how many minutes will Emma have worked?

Answers

Answer:

Start with 30 assembled, parts for 100 more.

Each minute results in +1/8 and -1/10

So we want

30 + x/8 - x/10 = 35

x/8 - x/10 = 5

5x - 4x = 200

x = 200 minutes

During 200 minutes, 25 are assembled, 20 are disassembled,

resulting in a net gain of 5, added to the original 30.

Bike ride:

Total distance: 40 km

Desired average speed 20 km/hr

Total time will be 2 hours

20 km at 15 km / hr = 4/3 hour taken

Leaves 2/3 hour for 20 km

20 km in 2/3 hour = 30 km/hr

Gas mileage:

Let m = city mileage

m + 3 = highway mileage

136 / (m+3) + 155 / m = 9

9m^2 - 264m - 465 = 0

m = 31 (discarding negative value)

Bricklaying:

Let b = number of bricks in wall

Lisa lays b/9 bricks per hour

Lauren lays b/10 bricks per hour

b = 5 * (b/9 + b/10 - 10)

b = 5b/9 + 5b/10 - 50

90b = 50b + 45b - 4500

b = 900

Lisa does 100 per hour

Lauren does 90 per hour

Together they do 180 per hour.

Emma will have worked for 200 minutes.

Given, there are 30  assembled T works in the room initially.

A T work takes eight minutes to assemble, so the rate of assembling T work in one minute will be [tex]\frac{1}{8}[/tex].

Similarly, a T work takes 10 minutes to disassemble. so the rate of disassemble of T work will be  [tex]\frac{1}{10}[/tex].

Let Emma worked for x min.

According to the question,  Emma starts assembling T works as Ed begins disassembling the ones that were already made and they both continue to work until there are exactly 35 assembled T works in the room. So we can write it in equation for form as,

[tex]30+\frac{x}{8} -\frac{x}{10} =35[/tex]

[tex]\frac{x}{8} -\frac{x}{10}=5\\[/tex]

[tex]\frac{5x-4x}{40} =5[/tex]
