<span>A rabbit’s heart rate should be 120-150 beats per minute so you just multiply 120 by 60 and 150 by 60 and the numbers in between that should be the amount of times a rabbit hearts beats in one hour. 60 x 120 = 7,200 and 60 x 150 = 9,000. A rabbit's heart beats between 7,200 and 9,000 times an hour. </span>
420/3 = 140 rubies
Since they use 20 rubies you would do the total amount of rubies by 20.
140/20 = 7
Answer:
B. (13√2)/2
Step-by-step explanation:
Let L represent the length of one leg of the triangle. We note that the triangle is isosceles, so both legs are the same length. Then the Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the legs:
13² = L² + L²
13² = 2L²
13 = (√2)L
L = 13/√2 = (13√2)/2 . . . length of one leg
_____
To "rationalize the denominator", we multiply the fraction 13/√2 by (√2)/(√2). The result is (13√2)/2.
Answer:
y = 5.5x - 17
Step-by-step explanation:
(4,5)(2,-6)
- M = ∆y/∆x
- -6-5/2-4
- -11/-2 this is the gradient
- chose any of the point then introduce another point
- (4,5) (x,y) the gradient is -11/-2
- M =∆y/∆x
- y-5/x-4 = -11/-2
- -2(y-5) = -11 ( x -4)
- -2Y + 10 = -11x + 44
- -2Y = -11x + 44 -10
- -2Y = -11x + 34
- divide the while equation by -2
- y = 5.5x + - 17
- y= 5.5x - 17
