Answer:

150 meters is your answer hun.

Answer:

A. 0.545454 - 1/4 = 0.295454  yes this is an irrational number

C. 3.4641016 - 1/4 = 3.2141016  yes this is an irrational number

Step-by-step explanation:

A. 0.545454 - 1/4 = 0.295454  is an irrational number as the closest fraction is shown below at 3 decimal points only

As this can be converted to a fraction 147727 /500000  ≈ 0.295

B. - 4/9 - 1/4 = -0.694444444 is not an irrational number so answer is no

As this can be converted to a fraction  -173611111 / 250000000

To write 0.694444444 as a fraction you have to write 0.694444444 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

0.694444444 = 0.694444444/1 = 6.94444444/10 = 69.4444444/100 = 694.444444/1000 = 6944.44444/10000 = 69444.4444/100000 = 694444.444/1000000 = 6944444.44/10000000 = 69444444.4/100000000 = 694444444/1000000000. Then divide by 470 and we know to use this some as 250000000/531915 = 470

C. 3.4641016 - 1/4 = 3.2141016  yes this is an irrational number

closest fraction is only   4 significant figures

4017627 /  1250000

=3 and 267627 over 12500003

267627  /1250000

≈3.214  so in closer proof it is an irrational number.

D. sq rt 4 - 1/4 = 1.75 is not an irrational number as this fraction is 7/4 = 1 3/4

you would try all becauseyou all try you are intilligent mare than other

Question:- Write ⅝ as a percent

Answer:-

[tex] \frac{5}{8} [/tex]

For making it in percentage we need to multiple the fraction with 100

[tex] \frac{5}{8} \times 100\% \\ \frac{5}{ \cancel{8} {}^{ \: \: \: 2} } \times \cancel{100} {}^{ \: \: \: 25} \\ \frac{5 \times 25}{2} [/tex]

Now we will multiple and divide the above equation with 5 for easy solution. Or you can just divide the equation upto decimal for your answer

[tex] \frac{125}{2} \times \frac{5}{5} \\ \frac{625}{10} \\ 62.5 \: \% \: \: ans[/tex]

So your options (B) 62.5% is correct

Steps:

6 1/4 - 4 3/15 can also be written as 25/4 - 23/5

The LCD of 4 and 5 is 20.

That gives us 125/20 - 92/20.

Now, just subtract the numerators (leave the denominators the same).

That brings us to 33/20, which can be simplified to 1 13/20

Final Answer:

[tex]1\frac{13}{20}[/tex]

--------------------------------------------------------------------------------------------------------------

*Please mark brainliest if that helped!*

Answer:

1 [tex]\frac{13}{20}[/tex]

Step-by-step explanation:

1. Convert both [tex]\frac{1}{4}[/tex] and [tex]\frac{3}{5}[/tex] into a common denominator. 4 multiplied by 5 is 20. 20 works for both 4 and five. So convert the denominator into 20. Multiply [tex]\frac{1}{4}[/tex] by [tex]\frac{5}{5}[/tex] and multiply [tex]\frac{3}{5}[/tex] by [tex]\frac{4}{4}[/tex]

2. You should've gotten, [tex]\frac{5}{20}[/tex] and [tex]\frac{12}{20}[/tex]

3. 6 - 4 = 2, so 2 [tex]\frac{5}{20}[/tex] - [tex]\frac{12}{20}[/tex]

4. You have to convert 1 into [tex]\frac{20}{20}[/tex] and add that to [tex]\frac{5}{20}[/tex]. You should've got [tex]\frac{25}{20}[/tex]

5. Subtract.

The Answer is 1 [tex]\frac{13}{20}[/tex]

I believe I am correct.

Answer:

1/2^2

Step-by-step explanation:

When you have a number to a negative power, you can rewrite it inverting it's fraction and changing the signal of the power. 2 can be wrote as a fraction like 2/1, so you have 2^-2, it's like 2^-2/1, so you invert the fraction and the signal of the power, and have 1/2^2

Answer:

(1 1/4, -3/4)

Step-by-step explanation:

The x value, it is 1 and 1/4 units to the right of 0 so its 1 1/4

The y value, it is 3/4 units below 0 so -3/4

Coordinates = (x,y) so it is (1 1/4, -3/4)

accoding to the web "He started out 25 meters below the edge of the volcano. It takes him 6.25 seconds to reach the edge."

Answer:

25 meters below the edge; 6.25 seconds  

Step-by-step explanation:

We can represent this with a linear function in slope-intercept form.  

We know the rate of change is 4 since he climbs up at 4 meters per second.  We do not know the value of b, the y-intercept.  

This gives us  

y = 4x + b  

We know that he is 13 meters below the edge after 3 seconds.  Using -13 for y and 3 for x,  

-13 = 4(3) + b  

-13 = 12 + b  

Subtract 12 from each side:  

-13-12 = 12+b-12  

-25 = b  

This gives us the equation  

y = 4x - 25  

He started out 25 meters below the edge of the volcano.  

To find how long it took him to reach the edge, substitute 0 in for y:  

0 = 4x - 25  

Add 25 to each side:  

0+25 = 4x-25+25  

25 = 4x  

Divide both sides by 4:  

25/4 = 4x/4  

6.25 = x  

It takes him 6.25 seconds to reach the edge.

Answer:

Answer:

d

Step-by-step explanation:

Step-by-step explanation:

it is really not complicated. we only need to type the numbers into the calculator.

so, what's the problem ? you don't know what a perimeter is ? it is the circumference, the total way you have to go when waking all around the figure.

you don't know the formulas for the areas of specific figures ?

let's start :

a)

the area of a rectangle is length×width. I hope you know this at least since first grade.

the important thing here is : the result is in² and not just in. it means an area counts the little squares that fill that area.

A = 30×8 = 240 in²

the perimeter, as explained, is the whole way around it. so, in the end, as you can easily see, we would have to go 2 times the long side and 2 times the short side.

the result is in (just a length, a distance not an area, not a cube, ...).

P = 2×30 + 2×8 = 60 + 16 = 76 in

b)

the area of a triangle is

baseline × height / 2

in this case (a right-angled triangle) we can assume one of the sides enclosing the 90 degree angle as baseline and the other as height (since there is already a 90 degree angle between them).

and again, the result is ft². we could express it also e.g. as in², but since the basic measures are in ft, it makes it better understandable to use ft².

A = 12×5/2 = 6×5 = 30 ft²

the perimeter is even easier than for the rectangle, as we have one side less to count.

and as before, we stay with ft.

P = 12 + 13 + 5 = 30 ft

c)

this is the only more special case.

but it is still easy.

the area is baseline × height.

and our unit of measurement here is cm, so the result will be cm².

A = 10×2 = 20 cm²

the perimeter is the same principle as with a regular rectangle, as the angles don't matter. only the side lengths matter.

so, again, while waking around it, we have to pass 2 times the long side and 2 times the short side.

and the result is a length, a distance again, so, it is cm.

P = 2×10 + 2×4 = 20 + 8 = 28 cm
