Answer:
32 hours
Step-by-step explanation:
First setup an equation
500 + 22x = 1204 the x represents how many hours she worked an that is what we want to know. So to find out x you do this......
22x + 500 = 1204
1204-500= 704
704/22 = 32
So, X = 32 hours
Since b is the midpoint BC is half the line so we can set up this equation
x+4+X+4=3x-8
and then solve like normal
2x+8=3x-8
16=x
once you have x then solve x+4
16 + 4 =20
AB is 20
Answer:
So we have a triangle and a semicircle.
If the triangle is equilateral, this is:
AB = BC = 6cm
Then the area of the triangle is equal to (base*height)/2
in this case:
A = (6*6)/2 = 36/2 = 18cm^2.
And the diameter of the semicircle is equal to 6cm, then the diameter is 3cm
And if the area of a circle is A = pi*r^2
then the area of half a circle is:
A = (pi/2*)3^2 = pi*4.5cm^2
Then, the area of the triangle plus the area of the semicircle is:
Total area = 18cm^2 + pi*4.5^2
0.000565 - this is a simple standard form question (if the 10 is to the power of a negative number, the answer will always be extremely low!)
Answer:
y=+9
Step-by-step explanation:
y=mx+b
m is the slope and b is the y intercept, replace m with 0 and replace b with 9.
