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

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

Answer:

(6, 6)

Step-by-step explanation:

    Point P is located at (6, -4). Point S is located 10 units above point P. This means we are going up on the y-axis. Going up 10 units from -4 puts point S at 6. Therefore, point S is located at (6, 6).

Answer:

150 meters is your answer hun.

Answer:

125 10/14

Step-by-step explanation:

the 125 doesn't actually matter so you can ignore that part.

since it is being divided by 14, the denominator of the fraction is 14. the remainder is 10, so the answer should be in the form of x 10/14, which the 1st answer is

Step-by-step explanation:

3:6=3/6=1/2

28:36=28/36=7/8

4:9=4/9

4:9=4/9

8:16=8/16=1/2

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

Step-by-step explanation:

4√10x^2

Answer:

answer for your question is 2) 5 and 7

Answer:

1.

solution :

x+2x+2x=180degree(sum of angle of triangle )

5x=180degree

x=180/5

x=36

therefore, x= 36

2x=2*36

Answer:

y = 3x + 5

Step-by-step explanation:

Based on the table, as x increases by 1, y increases by 3. Moreover, when x = 0, y = 5. Therefore, the slope is 3 and the y-intercept is (0, 5).

Substitute the information for the variables in the slope-intercept form equation.

y = mx + b

Answer:

y=3x +5

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:

C. -4 degrees celsius

Step-by-step explanation:

Answer:

-4 degrees celsius

Step-by-step explanation:

you can see that there are 5 tiny lines between 0 and -10 so that must mean that 10 divided by 5 = 2. so each gap is equal to 2 degrees celsius. that means that the red liquid is upto the -4 point
