Answer: Length = 15 meters
Width = 2 meters
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
Area of a rectangle = l × w
where l = length
w = width
Therefore,
2l + 2w = 34 ...... i
l × w = 30 ........ ii
From equation i
2l + 2w = 34
Divide through by 2.
l + w = 17 ...... iii
Then, l = 17 - w ........ iv
Put equation iv into ii
l × w = 30
(17 - w) × w = 30
17w - w² = 30
w² - 17w + 30 = 0
w² - 15w - 2w + 30 = 0
w(w - 15) - 2(w - 15) = 0
(w - 2) = 0
w = 0 + 2 = 2
w - 15 = 0
w = 0 + 15 = 15
Length = 15 meters
Width = 2 meters

Which of the following is the midpoint of segment
AB
given that
A(−5,12) and B(3,−8)
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.

The length of a rectangle is 4 4 times the width. The area is 64 64 square centimeters. Find the length and width of the rectangle.
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

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

are 3:6 and 6:3 equivalent?
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
