Please helpp What is the area of the purple region? What is the area of the green region?

butalik [34]

what do we need to know:

the radius of the semi circles;

the area of:

purple region = area of a circle = pi * r^2;

green region = base * height;

what we know:

the base, 28m;

what the sum of the two diameters is, 28;

the length of a single diameter, 14;

what we can assume:

the two semi-circles are equal, as otherwise i cannot see a way to answer this;

the radius of the two semi-circles, 7m as the two diameters = 28, & d/2 = r

what does that mean:

the height is 17m

green region area = 476 m^2

purple region area is = 153.96 m^2

Solve the following equation for y, and then identify the slope of the line: 9x-3y=15

sashaice [31]

$9x-3y=15\ \ \ | subtract\ 9x\\\\
-3y=-9x+15\ \ \ | divide\ by\ -3\\\\
y=3x-5\\\\
y=ax+b\ \ a-\ slope\\\\
a=3\\\\Slope\ is\ equal\ to\ 3.$

Class interval __ Frequency

1400 - 1599 ____ 5

1600 - 1799 ____ 7

1800 - 1999 ____12

2000 - 2199 ___ 3

2200 - 2399 ___ 3

14-3(5t-12)=1-(20t+1) How am I supposed to do this?

Nuetrik [128]

Expand by multiplying out:

14-15t + 36 = 1 -20t -1,
Because of the minus before the bracket, it changes the sign inside the bracket
-15t + 20t = 1-1-14-36 Rearranging the ts on one side and the numbers on other
side.
5t = -50 Divide both sides by 5.
t = -50/5
t = -10.
