If Rie’s legs are 99cm long, and Rie is 165cm tall. What percentage of Rie’s body is legs?

Answers

Answer 1

The percentage of Rie's body that is Rie's legs is: 60%.

What is Percentage?

A percentage can be defined as an amount in each hundred or, simply put, a proportion of a quantity in relation of a whole.

How to Find the Percentage of a Quantity in a Whole?

To find the percentage of a quantity in a whole, divide the quantity by the whole quantity, then multiply the quotient by 100.

The "whole" in this problem is Rie's height, which is: 165 cm

The "quantity" in the context of this question is the length of Rie's leg, which is: 99 cm.

Therefore, to find the percentage of Rie's legs in Rie's body, we have the following:

99/165 × 100

= 0.6 × 100

= 60%.

Therefore, Rie's leg is 60% of Rie's body.

You had $30 yesterday. You spent 20% of it today. How much money do you have left?

Answers

ANSWER

$24

EXPLANATION

You had $30 yesterday and you spent 20% of it today.

Since you spent 20% of it, the percentage you will have left is:

100 - 20 = 80%

So, you have 80% of $30.

That is:

[tex]\frac{80}{100}\cdot\text{ 30 = \$24}[/tex]

Answer:

b x 8 = 40 and 40 / 8 =b

Step-by-step explanation:

well, 8 charms makes one bracelet, so add up 8 until you run out of charms:

8 8 + 8 = 16 16 + 8 = 24 24 + 8 = 32 32 + 8 = 40

We only have 40 charms, so we can make 5 bracelets!

Now, plug this number (5) back into the equations:

b x 8 = 40

(5) x 8 = 40

40 = 40

this checks out!

40 - 8 = b

40 - 8 = (5)

32 = 5

32 does not equal 5, so this equation doesn't work.

40 / 8 = b

40 / 8 = (5)

5 = 5

This equation works :)

b + 8 = 40

(5) + 8 = 40

13 = 40

13 does not equal 40, so this is also a bad equation..

since b x 8 = 40 and 40 / 8 = b both produced the right results, we know those two are our answers!

Answers

It is enough for him to use a simple random sample of 172 cars.

It is required that there are at least 10 successes and 10 failures to test a hypothesis that involves a proportion p in a sample of size n.

Following conditions are required for it:

1) np ≥ 10

2) n (1-p) ≥ 10

p = 6% = 0.06

n = 172

np = 172x0.06 = 10.322 ≥ 10172 (1-0.06) = 161.68 ≥ 10

First set x-2 to be 0. The result (x) would be 2. Then, try any number that is below 2, let’s say x=0. Substituting G(0) = |0-2|, you would get that y = 2. This is when you can draw a line starting from point P(2, 0) (for when y = 0) and passing through point P(0, 2) (for when x = 0). Now try any number for x bigger than 2, let’s say 4. Substituting that into the function, you get G(4) = |4-2|, which means y = 2. Now, you can draw a final line starting from P(2, 0) (for when y = 0), and passing through P(4, 2) (for when x = 4). If the answer wanted to show a graph with this configuration, you'd get something in the lines of a V shape, with its point of convergence for y being 0 (I’m talking about the point when the 2 lines converge).

Answers

It is to be noted that by the proof given below, the attached shape ABCD is a kite.

What is a kite in Euclidean Geometry?

A kite is a quadrilateral having reflection symmetry across a diagonal in Euclidean geometry. A kite has two equivalent angles and two pairs of adjacent equal-length sides as a result of its symmetry.

The proof is as follows:

AB = AD [Given]

∠ADC = 115°   [Angles on a Straight line]

That is 180 - 65 = 115°

∠BCD = 20°    [Vertical Angles are equal]

∠ABC = (360 - (20+115+110))

= 115°              [Angles in a quadrilateral]

Hence,

ABCD = Kite    [Definition of  a Geometric Kit]

That is

Based on the number of inches in the drawing and the number of feet in real life, the scale that Paula used was 3 inches = 2 feet

What scale did Paula use?

The scale that Paula used was such that the stage was 56 feet long in real life but 84 inches long on the drawing.

The scale can therefore be shown by the ratio:

56 feet : 84 inches

If the number of inches is 3 then the number of feet in the scale would be:

56 feet : 84 inches

If a and b are two events defined on the same sample space, given that p(a) = 0.28 and p(aub) = 0.51, find the p(b) such that a and b are mutually exclusive

Answers

P(B) such that a and b are mutually exclusive is 0.23

A group of potential results from a specific experiment is an event. Events that do not take place at the same time are said to be mutually exclusive. For instance, if a coin is tossed, the outcome will either be head or tail; we cannot obtain both outcomes. Since they do not occur at the same time, such occurrences are also known as disjunct events.

Given: P(A) =0.28

P(AUB) = 0.51

We know,

P(AUB) = P(A) + P(B) - P(A∩B)

Since A and B are mutually exclusive events, they cannot happen together.

So, P(A∩B) = 0

Then,

P(AUB) = P(A) + P(B)

0.51 = 0.28+ P(B)

P(B) = 0.51 - 0.28 = 0.23.

Hence, P(B) = 0.23

The arc length is equal to the measure of the arc in radians only if the radius of the circle is 1 unit, for all the other circles this is false.

Is arc length equal to the measure of the radian?

For a circle of radius R, if we have an arc defined by an angle of θ radians, then the length of that arc is:

L = R*θ

Particularly, the length is equal to the measure in radians only if the radius of the circle is R = 1:

L = 1*θ
