Answer:

Step-by-step explanation:

angle 5 and angle 7 will add up 180

since angle 5 is congruent to angle 1 then angle 5 equals 120

angle 7 will come out to 60 degrees

180-120=60

Container A has radius r and height h . It holds a maximum of 44 ounces of water. Container B has radius 2.5r and height 4h .

Dennis_Churaev [7]

Set an equation:

$\pi r^{2} h$ =44
divide both sides by 3.14
$r^{2} h$ =14

$\pi (2.5r)^{2} 4h=x$
divide both sides by 6.25, 4, and 3.14
$r^{2} h$ =x/78.5

Since these two equations are equal, we can set them up that way.

x/78.5=14
multiply both sides by 78.5
x=1099

Answer: The maximum amount of water that container B can hold is 1,099 ounces.

In the coordinate plane, find the distance between the points using absolute value.

alukav5142 [94]

Answer:

The distance between the two points is 8 units

Step-by-step explanation:

In the given figure

∵ The coordinates of the 2 points are (4, 5) and (4, -3)

∴ x1 = 4 and y1 = 5

∴ x2 = 4 and y2 = -3

∵ Their x-coordinates are equal

→ That means the distance between them is vertical

∴ The length of the vertical distance between two points is

the difference between the y-coordinates of the points

∵ The distance between them = Iy2 - y1I

∵ y1 = 5 and y2 = -3

∴ The distance between them = I-3 - 5I

∴ The distance between them = I-8I

→ Remember absolute value gives always positive values

∴ The distance between them = 8 units

∴ The distance between the two points is 8 units

Martin had M dollars initially. First, Martin spent 1/3 of his money. Then Martin spent 3/4 of what was left. Finally, Martin sp

Ilya [14]

Answer:

first he had M some unknown amount

then he had 2/3 M since he spent 1/3 M

then he spent 3/4 of the (2/3 M) so he had 1/4 of the ( 2/3M)

then he spent what was left $20 so $20 = 1/4 ( 2/3 M) now solve for M

and check by doing each step and figuring how much was spent and how much left.

another method 

let us consider the left amount be Y and total now of M dollar be X

then

Y = amount of money Nartin has left

Y = X - ( 1/3 ) ( X ) - ( 3/4 ) ( X - 1/3 X ) - 20

Y = X - 1/3 X - 3/4 X + 3/12 X - 20

Y = X - 4/12 X - 9/12 X + 3/12 X - 20

Y = X - 10/12 X - 20

Y = X - 5/6 X - 20

Y = ( 1 / 6 ) ( X ) - 20

hope it helped u buddy : )
