15 / 21 = 75 / x.....15 shots to 21 grams = 75 shots to x grams
cross multiply
(15)(x) = (75)(21)
15x = 1575
x = 1575 / 15
x = 105 grams <===

Take 75 *21 to get 1,575 mass then divide it by 15 shots and you will get 105.the mass to be expected is 105

Answer:

A) Commutative

Step-by-step explanation:

The Associative has to do with re-grouping numbers. There are only two numbers so this does not apply here. Commutative is where you change the order; that's what the equation is demonstrating.

2. There are 18 other bottles in the fridge, because .6 of 30 is 18. 30 – 18 is 12, so there are 12 bottles of orange juice and cranberry juice.

4. If the probability of an event is 25%, then the probability of <em>not</em> that event is the other part of 100%. In other words, 1 – .25 = .75.

The equation of the perpendicular bisector of BC with B(-2, 1), and C(4, 2) is y = 7.6 - 6•x

<h3>Which method can be used to find the equation of the perpendicular bisector?</h3>

The slope, <em>m</em>, of the line BC is calculated as follows;

  • m = (2 - 1)/(4 - (-2)) = 1/6

The slope of the perpendicular line to BC is -1/(1/6) = -6

The midpoint of the line BC is found as follows;

\left( - 2 +  \frac{4 - ( - 2)}{2}, \: 1 +  \frac{2 - 1}{2}   \right) = (1,\: 1.5)

The perpendicular bisector is the perpendicular line constructed from the midpoint of BC.

The equation of the perpendicular bisector in point and slope form is therefore;

(y - 1.5) = -6•(x - 1)

y - 1.6 = -6•x + 6

y = -6•x + 6 + 1.6 = 7.6 - 6•x

Which gives;

  • y = 7.6 - 6•x
