What percent of 42 is 28

1 answer:

6 0

We can create an equation.

What percent is x

'of' indicates multiplication

'is' indicates an equal sign

So we have:

x * 42 = 28

42x = 28

Divide 42 to both sides:

x = 2/3

Multiply by 100 to convert to a percentage.

x = 66 2/3 %

How many license plates in Ontario were registered between the following licence plates? As the question is asking for plates be

Liono4ka [1.6K]

The number of plates is an illustration of permutation and combination

The number of plates is 2592

<h3>How to determine the number of plates</h3>

The range is given as: AVVJ 144 To: BVNP 199 (exclusive)

From the range, we have the following highlights:

The first letter can be either A or B (i.e. 2 letters)
The second letter can be only V (i.e. 1 letter)
The third letter can be from W to M (24 letters)
There are 54 numbers between 144 and 199

The number of plates (n) is then calculated as:

$n = 2 * 1 * 24 * 54$

Evaluate the product

$n = 2592$

Hence, the number of plates (n) is 2592

Which statement best describes the triangle formed by joining the points A(-3,6),B(-11,2),C(-4,-2)

Vikki [24]

Answer:

Isosceles triangle

Step-by-step explanation:

Length of side AB = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

= $\sqrt{(-11+3)^2+(2-6)^2}$

= $\sqrt{64+16}$

= $\sqrt{80}$

= 4 $\sqrt{5}$

Length of BC = $\sqrt{(-4+11)^2+(-2-2)^2}$

= $\sqrt{49+16}$

= $\sqrt{65}$

Length of AC = $\sqrt{(-3+4)^2+(6+2)^2}$

= $\sqrt{1+64}$

= $\sqrt{65}$

Since, AC = BC, ΔABC will be an isosceles triangle.
