Hey there!

Use this guide so you can tackle problems like this in the future to yourself! ⬇️

• Negative (–) & Negative (–) = Positive (+)

• Positive (+) & Negative (–) = Negative (–)

• Negative (–) & Positive (+) = Negative (–)

• Positive (+) & Positive (+) = Positive (+)

Based on the information/guide we now know our answer has to be a NEGATIVE number because we have a positive and negative in the equation!

18 ÷ -9 = -2

Thus your answer answer is most likely: -2 ☑️

Good luck on your assignment and enjoy your day!

The probability of spinning vanilla ice cream with chocolate a rainbow sprinkles is 1/12

<h3>The missing part of the question</h3>

Flavor of ice cream: Vanilla, Strawberry, Chocolate

Topping: Rainbow sprinkles, Caramel sauce, Nuts, Cherries

<h3>The number of different combinations</h3>

Using the dataset above, we have:

Ice cream = 3

Topping = 4

The number of different combinations is calculated as:

Combination = ice cream * Topping

Evaluate

Combination = 3 * 4

Combination = 12

Hence, the number of different combinations is 12

<h3>The probability of spinning vanilla ice cream with chocolate a rainbow sprinkles</h3>

The vanilla ice cream with chocolate a rainbow sprinkles is just one of the 12 combinations.

So, the probability is:

P = 1/12

Hence, the probability of spinning vanilla ice cream with chocolate a rainbow sprinkles is 1/12

16. Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.

il63 [147K]

Answer:

Given equation are:

$y = -\frac{1}{4}x+8$ ......[1]

$-2x+8y = 4$ .....[2]

The two lines are parallel lines then their slopes will be equal.

When two lines are perpendicular then, the slope of lines are the negative reciprocals of each other.

Now, Equation of a line is in the form of y =mx+b where m is the slope of the line.

Slope $(m_1)$ of equation of line in [1] is;

$y = -\frac{1}{4}x+8$

then;

$m_1= -\frac{1}{4}$

Slope $(m_2)$ of equation of line in [2];

$-2x+8y = 4$

Add both sides 2x we get;

-2x + 8y + 2x = 2x + 4

Simplify:

8y = 2x +4

Divide both sides by 8 we get;

$y = \frac{1}{4} x + \frac{1}{2}$

then;

$m_2 = \frac{1}{4}$

Therefore, the given two lines are neither parallel nor perpendicular.

Hello!

The volume of a cone is Volume = 1/3πr²h.

V = 1/3π(10)²(9)
= 1/3<span>π100(9)
</span>= 1/3<span>π900
= 300</span>π cm³

Therefore, the volume of this right cone is 300<span>π cm</span>³.
