Answer:
544 blood cells.
Step-by-step explanation:
the number of blood cells is 17 times the weight of the animal 32 =544 blood cells pass through a major artery every millisecond
To find "s", you can use the Pythagorean theorem(which you can only use for right triangles):
a² + b² = c² (c is the hypotenuse/the longest side of the triangle)
t = 18 (hypotenuse)
r = 12
s = ?
Plug in the numbers into the equation
a² + b² = c²
(12)² + b² = (18)²
144 + b² = 324 Subtract 144 on both sides
b² = 180 Square root both sides
b = √180 or 13.4

Point slope is nicer
y-y1=m(x-x1)
goes through the point (x1,y1) and has a slope of m
slope itnercept
y=mx+b
m=slope
b=y intercept
first find slope
slope between 2 points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(7,82) and (4,18)
slope=(18-82)/(4-7)=-64/-3=64/3
point slope
point is (7,82) or you can do (4,18)
I'll do both
y-82=(64/3)(x-7) or
y-18=(64/3)(x-4)
those both work
slope intercept
slope is 64/3
y=64/3x+b
find b
input a point
(4,18)
18=64/3(4)+b
18=256/3+b
minus 256/3 from both sides
note: 18=54/3
-202/3=b
y=64/3x-202/3 is equation in slpe intercept
Answer:
x = 41°
∠1 = 123°
∠2 = 57°
Step-by-step explanation:
If angles 1 & 2 are supplementary, that means...
To find the value of each angle, you first must find the value of x by plugging in the values of both angles...
First, combine like values, then subtract add 25 to both sides.
Then, divide both sides by 5, and plug the value of x into the original equations for angles 1 & 2.
