Answer:

A. 20

Step-by-step explanation:

To solve this you must know that the angles marked are vertical angles and are congruent. So, you should set them equal to each other

x+40=3x

you would subtract x from both sides

40=2x

and then divide 2 from both sides

20=x

hope this helped!

Reasoning triangle $abc$ has a perimeter of $12$ units. the vertices of the triangle are $a(x,\ 2),\ b(2,-2)$ , and $c(-1,\ 2)$

OlgaM077 [116]

hmmm let's find the distance between B and C first off.

$~~~~~~~~~~~~\textit{distance between 2 points} \\\\ B(\stackrel{x_1}{2}~,~\stackrel{y_1}{-2})\qquad C(\stackrel{x_2}{-1}~,~\stackrel{y_2}{2})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ BC=\sqrt{(~~-1 - 2~~)^2 + (~~2 - (-2)~~)^2} \implies BC=\sqrt{(-1 -2)^2 + (2 +2)^2} \\\\\\ BC=\sqrt{( -3 )^2 + ( 4 )^2} \implies BC=\sqrt{ 9 + 16 } \implies BC=\sqrt{ 25 }\implies BC=5$

hmmm if BC is that much, then AB + AC = 7, since AB + AC + BC = 12 which is the perimeter, Check the picture below.

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 a survey 25% of the people said they live in a city of 60 people said they live in a city how many people were surveyed

alisha [4.7K]

Step-by-step explanation:

You said:

'25% of the people = 60 people "

' 25% ' means 0.25

'of ' means ' times'

So people (0.25) x (the people) = 60

the people=60/0.25

the people=6000/25

the people=240
