Answer: 240 square foot room
Step-by-step explanation: They ask for how many square feet in 1 hour which is double the 1/2 hour. So, just do 120x2=240 to get your answer! (Don’t forget to label ,square-feet,)
Answer:
n=12
Step-by-step explanation:
3.3(n-8)-n=1.2
Distribute
3.3n -26.4 -n = 1.2
Combine like terms
2.3n -26.4 = 1.2
Add 26.4 to each side
2.3n -26.4+26.4 = 1.2 +26.4
2.3n = 27.6
Divide each side by 2.3
2.3n/2.3 = 27.6/2.3
n=12
X = number of students who are members.
<span>19-x is the number of people who are not members.</span> x number of people paid $11 for tickets and (19-x) number of people paid $13.$11x+$13(19-x)=$209 for the total cost of the tickets.
$11x+ $247-$13x=$209 $11x-13x = $209 - $247
$-2x = $-38
divide -2 by both sides
x=19, meaning that all of the students are members.
Answer:
![x=12](https://tex.z-dn.net/?f=x%3D12)
Step-by-step explanation:
Since the segment EF appears tangent to the circle, we are assuming that it it is actually tangent.
This assumption gives us a right triangle with base
(because it the radius of the circle), a perpendicular of
, and a hypotenuse of
; therefore, from the Pythagorean theorem we have
.
Upon expanding the expression on the right side, we get
.
Subtract
from both sides:
,
and solve for ![x](https://tex.z-dn.net/?f=x)
![x=\dfrac{35^2-25^2}{50}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B35%5E2-25%5E2%7D%7B50%7D)
![\boxed{x=12}](https://tex.z-dn.net/?f=%5Cboxed%7Bx%3D12%7D)
Find two points- pick any number and replace it with x and then solve for y. Write it in the following format: (x, y). Pick another number for x and repeat this process.
Graph these two points: One point that would work in the equation is (4, 0). start at the origin- (0, 0)- and move horizontally by positive four, meaning you move four to the right (if it was negative, you would move four units to the left). Then, because the y-value is zero, you don't move up or down. If you had a positive y-value, the point would go up, and if it was negative, it would go down. Since it is 0, it stays in place. This makes this specific point an x-intercept because it intersects with the x-axis.
You would do the same with the other point and connect them with a ruler, extending out the line and putting arrows at either end of it to signify the it goes on forever.
