Answer 1

Answer:

Let's see -

Let's solve the first question step-by-step

(WARNING - This may confuse you a little)

4 1/8 + 2 1/3

= 33/8 + 2 1/3

= 33/8 + 7/3

= 155/24

= 6 11/24 --------> Note that this is your final answer and it already looks simplified down to its simplest form. :)

2) This equation, as far as solving it, is no different than number 1. Let's go for it!

5 17/18 - 2 2/3

= 107/18 - 2 2/3

= 107/18 - 8/3

= 59/18

= 3 5/18 -----------------> This is your final answer, and, as before, it looks simplified enough.

Answer with explanation:

Formula used here ,

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

It is given that the distance between Meredith and her friends house =2 4 blocks

Then At Speed = 1 block per minute.

$\text{Time}=(24)/(1)$ = 24 minutes.

At Speed = 2 block per minute.

$\text{Time}=(24)/(2)$ = 12 minutes.

At Speed = 3 block per minute.

$\text{Time}=(24)/(3)$ = 8 minutes.

At Speed = 4 block per minute.

$\text{Time}=(24)/(4)$ = 6 minutes.

At Speed = 6 block per minute.

$\text{Time}=(24)/(6)$ = 4 minutes.

At Speed = 8 block per minute.

$\text{Time}=(24)/(8)$ = 3 minutes.

At Speed = 10 block per minute.

$\text{Time}=(24)/(10)$ = 2.4 minutes.

At Speed = 12 block per minute.

$\text{Time}=(24)/(12)$ = 2 minutes.

At Speed = 24 block per minute.

$\text{Time}=(24)/(24)$ = 1 minute.

This problem can be solved by using the formula for

linear motions. The formula relating velocity, distance and time is:

t = d / v

where t is time, d is distance and v is velocity

We are given that d = 24 blocks

When v = 1 block / minute

t = 24 blocks / (1 block / minute)

t = 24 minutes

When v = 2 block / minute

t = 24 blocks / (2 block / minute)

t = 12 minutes

Hence we can see that it takes half the time when she is

travelling at 2 blocks per minute.

Jeff had reached the highest level in his new computer game. The computer reported his score as 1.35x10^5 points. How should Jeff write his score in standard form?

Answers

Answer:

135,000 points

Step-by-step explanation:

An easier way to solve these type of questions is to understand that the $10^(5)$ is basically asking you to move the decimal point 5 spaces to the right, adding a zero in every free spot. So 1.35x10^5 would be

1.35x10^5 = 135000

In other words Jeff's high score written in standard form would be 135,000

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

you have to use pemdas or as other people call it ...

(p)lease (e)xcuse (m)y (d)ear (a)unt (sa)lly
parenthesis exponents multiply divide add subtract
you start with the exponent and you take 10 to the 5th power
that will equal 100000
so now you have 1.35x100000=135000

1/2 × 9 =

Answers

1/2 x 9
9 can also be expressed as 9/1 and when we multiply fractions, the numerators and denominators are simply multiplied, easy as that
1/2 x 9/1
9/2 is your answer, which can also be written as 4 and 1/2 or 4.5

The answer is................... 4 1/2

A rational number can be written as the ratio of one blank to another and can be represented by a repeating or blank decimal

Answers

we know that

A rational number is the quotient of two integers with a denominator that is not zero , and can be represented by a repeating or terminating decimal.

Repeating Decimal is a decimal number that has digits that go on forever

Terminating decimal is a decimal number that has digits that do not go on forever.

examples

$(1)/(3) = 0.333...$ (the $3$ repeats forever)----> Is a Repeating Decimal

$0.25$ (it has two decimal digits)----> Is a Terminating Decimal

therefore

the answer is

A rational number can be written as the ratio of one $integer$ to another and can be represented by a repeating or $terminating$ decimal

A rational number can be written in the form:

$(p)/(q); \ called \ the \ ratio \n \n where \ p \ and \ q \ are \ whole \ numbers$

The number $q$ isn't equal to zero because the division by zero is not defined. So we can represent rational numbers by a repeating or terminating decimal, for instance in the following four exercises we have:

$(2)/(3)=0.6666...=0.\stackrel{\frown}{6} \n \n (5)/(8)=0.625000...=0.625\stackrel{\frown}{0} \n \n (3)/(1)=3.000...=3.\stackrel{\frown}{0} \n \n (3446)/(2475)=1.392323...=1.39\stackrel{\frown}{23}$
