Answer:

120

Step-by-step explanation:

12x10=120

To get a percentage you normally divide, and the opposite of division is multiplication so that's how we got the whole number.

17ft, 1 student

Step-by-step explanation:

Answer:

answers to questions 1, 2, and 4 are all the same; 20 - 11 = 9

answer to question 3 is 24 - 1 = 23

Step-by-step explanation:

Answer:

23 and 9

Step-by-step explanation:

Find the difference of the greatest value and the least value of the data.

20-11=9

24-1=23

Answer:

20/3

Step-by-step explanation:

By the property of equal intercepts made by transversals on parallel lines.

[tex] \frac{4x - 3}{x + 17} = \frac{1}{1} \\ \\ 4x - 3 = x + 17 \\ \\ 4x - x = 17 + 3 \\ \\ 3x = 20 \\ \\ x = \frac{20}{3} \\ \\ [/tex]

Answer:

C= 10.6

Step-by-step explanation:

AB^2=AC^2+CB^2

C^2=7^2+8^2

C^2= 113

√113=10.630

Answer:

(-1, 2)

Step-by-step explanation:

Finding the midpoint of a line, having been given two points, is like finding the average coordinate of those two points.

To find the average x coodinate (and hence the midpoint's x coordinate), you have to sum the x coordinates and divide by 2 - like finding the mean.

To find the y coordinate, sum the y coordinates and divide by two.

[tex](x,y) = (\frac{-5+3}{2} , \frac{12+-8}{2} )[/tex]

Answer:

Step-by-step explanation:

(12 - 8)/2 = 4/2 = 2

(-5 + 3)/2 = -2/2= -1

Answer:

Width of a rectangle = 4 cm

Length of a rectangle = 16 cm

Step-by-step explanation:

Let width of a rectangle be [tex]x[/tex] cm.

The length of a rectangle is 4 times the width.

Length of a rectangle [tex]=4x[/tex] cm

Area of rectangle [tex]=64[/tex] square centimeters.

Also,

Area of rectangle = length × breadth

[tex]64=4x(x)\\64=4x^2\\16=x^2[/tex]

± [tex]x=4[/tex]

Being a dimension, [tex]x[/tex] can not be negative.

So,

[tex]x=4[/tex] cm

Width of a rectangle = 4 cm

Length of a rectangle = 4(4) =16 cm

if you see where the red line ends on the right side it is at 170 on the protractor

Answer:

No

Step-by-step explanation:

3:6 is a ratio saying for every 3, there's 6, or just convert them into fractions, like 3:6 is 3/6 and 6:3 is 6/3,

so is 3/6 = 6/3, no so they aren't equivalent

Answer:

its d

Step-by-step explanation:

the slope is -20 because for every 30 seconds the altitude gets smaller by 600 feet. 600/30=20 so its going down 20 feet per second.

Answer:

B.) 20.020

C.) 20.02

D.) 20.2

Step-by-step explanation:

2 x 10 = 20

2 x 1/100 + 20 = 20_1/50

20 x 50 + 1 = 1001

1001/50 = 20.02

or

20.2 (the 0 does not need to be there because the answer is the same  without it.)

or

20.020 (the last 0 does not need to be there because the answer is the same without it.)

Answer:

the vapor pressure of a solution at 25°C that contains 76.6 g of glucose (180.2 g/mole) in 250.0 mL of water. The vapor pressure of pure water at 25°C

Step-by-step explanation:

your answer is:  22.9 torr at 25°C

Explanation:

When a non volatile solute is added to a pure solvent, the vapour pressure of the mixture decrease regard to the pure solvent following the equation

Where vapour pressure of the pure solvent (Water) is 23.8torr at 25°C.

Mole fraction of water is the ratio between moles of water and total moles in solution. The solution has a mole fraction of water of:

Replacing in Raoult's law:

Vapor pressure of the solution is 22.9 torr at 25°C

hope this helps!
