Answer:
x=18-y Answer will be (0,9) (8,5)
Step-by-step explanation:
3x - 2y = 20
Subtract 3y from both sides to get the y-variable on one side of the equal and the rest on the other.
-2y = - 3x + 20
Now divide by -2 on both sides to isolate the y-variable.
y = -3x/-2 + 20/-2
y = 3/2x - 10
Answer:
Kevin need 14.14 feet of red tape
Step-by-step explanation:
Given: (Figure Attached)
Area of Square = 25 square feet
As we know
Area of square = length x width = a x a = 25
a * a = 25
a = ±5 by taking square root both sides
It means a = 5 as the length can not be negative
Now we know the length of sides of square and as shown in figure we can break the figure in two triangles,
By using Pythagoras theorem on one triangle we will find the length of one line of x and then multiply the x with 2 to get the overall feet of tape.
=
= 

x = ± 7.07 It means x = 7.07
Now the total tape required is 2 * x = 2*7.07 = 14.14
Answer:
13.08
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 * 5^2
A =3.14 *25
A =78.5
The angle of the purple sector is 60 degrees
A full circle is 360 degrees
The fraction of the circle that is purple is 60/360 = 1/6
Multiply the area of the circle by 1/6
1/6* 78.5 =13.0833333
Rounding to the nearest hundredth
13.08
365 days in 1 yr
so if 33,300 citizens died in 1 yr....(or 365 days)....then..
33,300/365 = 91.2 rounds down to 91 deaths per day.
