For each question, there are two options: True or False. Thus, if you guess on all of the questions, there is a 1/2 chance that you get the answer right.

If there are three questions on the test, the chance that you get a perfect score is:

1/2 * 1/2 * 1/2

When this is simplified, you get:

1/4 * 1/2

OR:

1/8

Therefore, the probability that you will get a perfect score is 1/8 or 12.5%

QUESTION POSTED AT 29/01/2020 - 05:24 PM

Ok so you need the surface area formula of a cone.

A = πrl + πr∧2

where π = 3.14 (pi)

r = half of the diameter (18/2 = 9)

l = slant hight ( 22 )

Slot this into the equation A = (3.14 [ rounded] )(9)(22) + (3.14 [ rounded] )(9)∧2 = 876.06 this is due to the rounded pi the answer is 876.5 i.e the third.

Hope this helps :D.

There are 360 degrees in the rhombus which means the equilateral triangles has 180 degrees (because it is half the rhombus and also it is the angle sum of a triangle). It is equilateral meaning all sides and angles are the same so they all must be 60 (180/3)

Now this must mean that angle a is equal to the opposing angle being 60

Now this must mean that angle a is equal to the opposing angle being 60

QUESTION POSTED AT 29/01/2020 - 04:33 PM

The density (d) is the quotient when mass (m) is divided by the volume (v). It is specified that the densities be in units of g/cm³. So, there is a need to convert first the given mass and volume to proper units. The calculations are shown below,

2 m³ x (100 cm / 1 m)³ = 2.0x10^6 cm³

1x10^4 kg x (1000 g/ 1 kg) = 1.0x10^7 g

Calculating for density,

d = m/v = (1.0x10^7 g) / (2.0x10^6 cm³) = 5 g/cm³

2 m³ x (100 cm / 1 m)³ = 2.0x10^6 cm³

1x10^4 kg x (1000 g/ 1 kg) = 1.0x10^7 g

Calculating for density,

d = m/v = (1.0x10^7 g) / (2.0x10^6 cm³) = 5 g/cm³

The first step to solving an equaiton of the formax2+bx+c = 0is by completing the square by first dividing by a, givingx2+bx/a+c/a = 0

then subtract c/a to both sides.

In this regard, the first step to the equation is to C. . Subtract 3 from each side of the equation..

then subtract c/a to both sides.

The scale factor of these two circles is the ratio of their radii. This is shown below,

sf = r1 / r2 = 6x/18y

Simplifying the fraction by dividing both the numerator and the denominator by 6 gives an answer of x/3y. Thus, the answer is letter A.

Given that the longest side is 20 cm, 3x < 20 and x <20/3

Other inequality that has to be checked is that the sum of two any sides has to be greater than the other.

Then 3x + x > 20

4x > 20

x > 5.

So the value of x is in the range (5, 20/3)
