Answer as many problems as you can

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

Answer:

The correct answer is 4(9)/6=3+2-1+2

Step-by-step explanation:

4x9 is 36..divided by 6 =6. then 3+2=5-1 is 4+2 is 6, so both sides are equal

Answer:

so italy is 7,500,000.00 and park is 21,100,000.00, 1997 is 3.40 and 1998 is 2.70

Step-by-step explanation:

Answer:

rounding means if like a number is 254 round it to the nearest hundred which would be 300 because if you can't round it to the nearest hundred you need to round to the nearest 10 which would be 30 plus the 4 on the end round that it would be 300.

Italy: 7,464,000,60

Pakistan: 21,079,00.30

1997: $3.40

1998: $2.70

Answer:

t=11/16

Step-by-step explanation:

4t+1/4=3

-1/4    -1/4

4t=2 3/4

t=11/16

Answer:

Step-by-step explanation:

4t+1/4=3

We move all terms to the left:

4t+1/4-(3)=0

determiningTheFunctionDomain

4t-3+1/4=0

We multiply all the terms by the denominator

4t*4+1-3*4=0

We add all the numbers together, and all the variables

4t*4-11=0

Wy multiply elements

16t-11=0

We move all terms containing t to the left, all other terms to the right

16t=11

t=11/16

t=11/16

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.

Step-by-step explanation:

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]

[tex]x=5\times40[/tex]

[tex]x=200[/tex]

Hence Emma have to work for 200 minutes.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

To do this, let's let the decimal equal n. Thus:

[tex]2.\bar1=n[/tex]

There is only one digit repeating, so let's multiply both sides of the equation by 10:

[tex]21.\bar1=10n[/tex]

Now, subtract n from both sides:

[tex]21.\bar1-n=10n-n[/tex]

On the right, it becomes 9n. However, the left, however, expand, the decimal. In other words:

[tex]21.1111...-2.1111...=9n[/tex]

All of the repeating 1s will cancel out. Thus:

[tex]21-2=9n[/tex]

Subtract:

[tex]19=9n[/tex]

Divide both sides by 9:

[tex]n=\frac{19}{9}[/tex]

And since we set the decimal equal to n originally...

[tex]2.\bar1=\frac{19}{9}[/tex]

And we're done!

Notes:

This is the algebraic way to write a repeating decimal into a fraction. You can, of course, always just use a calculator and guess and check.

It's A. 21/10

What I did to get this. Is i wrote down 2.1 as a fraction: 2.1/1 then multiplied 10 to both the numerator and the denominator. (2.1 x 10)/(1 x 10)=21/10.

I hope this helps. I'm not sure if the "repeating" matters that much to the point of a different answer...

Answer:

0.76

Step-by-step explanation:

Because this question is requiring you to divide a smaller number by a greater one you are going to have decimals or fractions.

The value of the division of the number 43.396 by 57.1 is 0.76.

A procedure of dividing anything into equal halves is called division. It is one of the four fundamental operations in math. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given numbers are 43.396 and 57.1. The value of the division will be calculated as below:-

Division = 43.396 / 57.1

Division = 0.76

Therefore, the value of the division of the number 43.396 by 57.1 is 0.76.

Hey there!

We can arrange this to say, "90% of the whole is 126."

Thus, we can write an equation, where w is used as a variable to represent the whole.

0.90w=126

Divide by 0.90

w=140

The whole is 140.
