Answer: 65%

$\frac{3250}{5000} * 100 \\13/20 *100 = 65%$

Step-by-step explanation:

To get the percentage of the seats in the theatre were filled by the 6th graders on the trip,

it will be

$\frac{occupied seats}{total seats} * \frac{100}{1}$

4x - 3y = 12 4x - 5y = -4 Solve using Elimination

mr_godi [17]

Answer:

${ \rm{4x - 3y = 12 - - - \{eqn(a) \}}} \\ { \rm{4x - 5y = - 4 - - - \{eqn(b) \}}}$

• subtract eqn(b) from eqn(a);

${ \underline{ \rm{ - \binom{4x - 3y = 12}{4x - 5y = - 4} }}} \\ { \rm{0x + 2y = 16}} \\ \\ { \rm{2y = 16}} \\ \\ { \boxed{ \tt{ \: \: y = 8 \: \: }}} \\$

• find x :

${ \rm{4x - 3y = 12}} \\ { \rm{4x - 3(8) = 12}} \\ { \rm{4x = 36}} \\ \\ { \boxed{ \tt{ \: \: x = 9 \: \: }}}$

HELPPPPPPPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

zvonat [6]

Let's take this step-by-step:

Part (a)

The mathematical name of this shape is a right trapezoid

⇒ It is a trapezoid since the image shows a quadrilateral that

has two parallel sides and two non-parallel sides. It is a right

trapezoid because it has two rights angles

Part (b)

The cube has 6 faces

⇒ faces are the individual flat surfaces of an object

⇒by looking at a picture of a cube, we see it has 6 sides

⇒ (I attached an image of a cube below)

Hope that helps!

Write an equation of the line in slope-intercept form: y-intercept of 2, x-intercept of 4

zvonat [6]

Answer:

$\sf y=-\dfrac12x+2$

Step-by-step explanation:

y-intercept is when x = 0, so (0, 2)

x-intercept is when y = 0, so (4, 0)

$\sf slope=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{0-2}{4-0}=-\dfrac12$

Slope-intercept form of linear equation: $\sf y=mx+b$

(where m is the slope and b is the y-intercept)

Given:

$\sf m=-\dfrac12$
b = 2

$\sf \implies y=-\dfrac12x+2$

tatiyna

Answer:

C is the answer

Step-by-step explanation:

The domain can't be minus. That's the only stipulation. It can be equal to 0 or anything larger than 0. It just can't go into the minus numbers.

0≤x<infinity.

9a- 24 >48 what is the solution

Artyom0805 [142]

Answer:

The solution to the given inequality is a > 8.

Step-by-step explanation:

For this problem, we have to solve for the inequality.

9a - 24 > 48

add 24 on both sides of the inequality.

9a > 72

Divide 9 on both sides of the inequality.

a > 8

So, your solution would be a > 8.
