Question 5 of 19
What is the fractional equivalent of the repeating decimal 0.4 ?
A. 4/99
B. 4/9
C. 2/5
D. 4/100

Answer:

Exact Form:  x = 7 3

Decimal Form:  x = 2. ¯ 3

Mixed Number Form:  x = 2  1 /3

Answer:

Step-by-step explanation:

Ok since they haven't specifically told use what the four consecutive numbers is we gotta use

X, x+1, x+2, x+3

Then you collect the like terms and sum them up

x+x+x+x+ 1 + 2 + 3 =278

4x+6=278

4x=272

Then you simplify

4x/4= 272/4

x=68

Now that you know what x is then the four consecutive numbers are 68, 69, 70, 71.

Adiosss

But the way I think I know do you have exams tomorrow??

let me know if this is wrong

Paragraph:

Functions are a special kind of relation. At first glance, a function looks like a relation. A function is a set of ordered pairs such as { (0, 1), (5, 22), (11, 9)}. Like a relation, a function has a domain and range made up of the x and y values of ordered pairs.

[tex]s^2=1^2+2^2\\s^2=1+4\\s^2=5\\s=\sqrt5[/tex]

s²=5 , so we look for the nearest squares, one less than 5 and the other greater.

First it would be perfect squares, which means 4=2² and 9=3²

4 < 5 < 9  so   2 <√5 < 3

now we'll do the same with the numbers with tenths, but to speed up we don't check them all. We do estimation for the square root knowing that it must be between 2 and 3

5 is close to 4 then 9, so I estimate 2.3 for its square root

(2.3)² = 5.29  - it is close but more then 5 so I look for less number then 2.3

(2.2)² = 4.84 - it is also close and less then 5 so:

4.84 < 5 < 5.29  therefore   2.2 < √5 < 2.3 and:

5 - 4.84 = 0.16  ; 5.29 - 5 = 0.29  

0.16 < 0.29  means the √5 is closer to 2.2 then 2.3

So the √5 rounded to the nearest tenth is 2.2

Of course is much easier if you can use the calculator. Then you have:

√5 = 2.2360679... ≈ 2.2         {because 3<5}

Answer:

[tex]58x-54=468[/tex]

Step-by-step explanation:

Number of repeat customers = 40

Amount charged from each of the repeat customers = $ x

So,

amount charged from 40 customers = $ 40 x

Number of new customers = 18

As Michel charged each of the new subscribers $3 less than the amount charged from each of the repeat customers,

amount charged from each of the new customers = $ (x - 3)

So,

amount charged from 18 new customers = $ 18(x - 3)

Total amount charged from repeat and new customers = [tex]\$[(40x)+18(x-3)]=\$40x+18x-54=\$58x-54[/tex]

As Michel collected $468 for delivering newspapers,

[tex]58x-54=468[/tex]

Answer:

3/2

Step-by-step explanation:

3^-4 x 2^3 x 3^2/2^4 x 3^-3

base 3 will be numerator and base 2 will be denominator:

3^-4 * 3^2 * 3^3 / 2^4*2^-3

Now add the exponents of the base:

3^-4+2+3/ 2^4-3

3^-4+5/ 2^1

3/2

The correct option is 3/2

Happy To Help!

===============================================

Work Shown:

A = old value = 3000

B = new value = 2250

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (2250-3000)/3000 ] * 100%

C = (-750/3000) * 100%

C = -0.25*100%

C = -25%

Since C is negative, we have a 25% percent decrease.

Another indication we have a percent decrease is that B < A.

Answer:

the answer is 427miles in 7 hours

Step-by-step explanation:

Answer:

427 miles in 7 hours.

Step-by-step explanation:

All we need to do is figure out how many miles per hour he's traveling, and then add it to the pre-existing 6 hour number we already have.

So, he drove 366 miles in 6 hours. We need to find out how many miles per hour (MPH) he's doing. To do this all we need to do is divide the amount of miles he's gone (366) by the number of hours it's taken him (6).  It looks like this:

366 ÷ 6 = 61.

So he's goes 61 miles every hour. Now all we need to do is add up until we hit 7 hours. We already know he went 366 miles in 6 hours, so we only need to add 61 to 366 once.

366 + 61 = 427.

427 is your answer.

Hope this helps and have a nice day!

Answer:

The temperature changed by [tex]-12^\circ F[/tex] overnight.

The temperature changed by [tex]-1^\circ F[/tex] overnight each hour.

Step-by-step explanation:

Given that:

Temperature at 7 PM last night = [tex]10^\circ F[/tex]

Temperature at 7 AM the next morning = [tex]-2^\circ F[/tex]

a. The change in temperature from 7 PM to 8 AM = Temperature at 7 AM - Temperature at 7 PM

[tex]\Rightarrow -2-10 =\bold{-12^\circ F}[/tex]

Negative sign indicates that the temperature has decreased.

b. Change in temperature each hour:

Divide the Change in temperature with the number of hours.

[tex]\Rightarrow \dfrac{-12}{12} = \bold{-1^\circ F}[/tex]

Negative sign indicates that the temperature has decreased.

Answer:

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know two points that a line passes through, this page will show you how to find the equation of the line.

Answer:

The correct option is;

c. The horizontal axis labeled Hours Driven goes from 0 to 15 in increments of 1 and the vertical axis labeled Miles Remaining goes from 0 to 150 in increments of 10. The line starts at left parenthesis (0, 0), and passes through (1, 65) and (2, 130)

Step-by-step explanation:

The given parameters are;

The speed of the truck = 65 miles per hour

The length of the highway = 130 miles

Therefore, from the given information, we have;

The time, t, it will take the truck to arrive at the end of the highway is given as follows;

Time = Distance/speed = 130/65 = 2 hours

Therefore, if the truck timing starts from the point (0, 0), we have;

The points on the straight line (constant) speed graph are;

(0, 0), (1, 65), and (2, 130)

Answer:

y = 3x+9

Step-by-step explanation:

We can use the slope intercept form

y = mx+b

where m is the slope and b is the y intercept

y = 3x +b

Substitute the point into the equation

6 = 3(-1) +b

6 = -3+b

Add 3 to each side

6+3 = -3+3+b

9 = b

y = 3x+9

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.
