Parallelogram p q s r is shown. the length of p q is (2 x 5) centimeters and the length of r s is (4 x 1) centimeters. in parallelogram pqsr, what is pq? 2 cm 5 cm 6 cm 9 cm

Answer:

a) P(1 and tails) = 1/10 = .1

b) P(even and heads) = 1/5 = .2

Step-by-step explanation:

The spinner has 5 outcomes: 1-5.

The coin has 2 outcomes: Heads or Tails.

We want to find the probability of P(1 ∩ T) and P(2,4 ∩ H).

Spinning the spinner and flipping the coin are independent events; therefore, getting one outcome has no effect on the outcome of another.

For independent events, the multiplication rule is:

If we use this formula for A, we get that:

The probability of getting a 1 on the spinner is P(1) = 1/5.

The probability of getting tails on the coin toss is P(tails) = 1/2.

We can now multiply these probabilities together:

The probability of getting a 1 on the spinner and tails on the coin toss is P(1 and tails) = 1/10 or .1.

There are two even numbers between 1 and 5: 2 and 4.

The probability of getting an even number on the spinner is 2/5.

The probability of getting heads on the coin toss is 1/2.

We can multiply these probabilities together:

The probability of getting an even number on the spinner and heads on the coin toss is P(even and heads) = 1/5 or .2.

60.7%

17:28

11/28

39.3%

11:28

Difference:  [tex]\frac{3}{14}[/tex]

Explanation:

A fraction can be turned into a percent by dividing the numerator by the denominator and multiplying the result by 100%.

For example:

17/28 = 0.607

0.607 * 100% = 60.7%

A fraction can be turned into a ratio by writing it like this:

numerator:denominator

For example:

11/28

11:28

To find the difference between 2 fractions with the same denominator, simply subtract the 2 numerators.

For example:

[tex]\frac{17}{28} - \frac{11}{28}[/tex]

You subtract 11 from 17, then put the resulting 6 in the fraction with the same denominator. This results in [tex]\frac{6}{28}[/tex] which can be simplified to [tex]\frac{3}{14}[/tex].

Answer:

A: 0.3318 m^2  P: 2.66

Step-by-step explanation:

The perimeter is only adding each of the side lengths, so that's not much of an issue. The equation for the area of a triangle is A = (b x h)/2, with "b" being the base length and "h" representing the triangle's height. We must first multiply the base and height, 0.84 x 0.79. This makes 0.6636 which we will then divide by 2. Our area is now proven to be 0.3318 square meters.

An equation is formed of two equal expressions. The amount of 20% milk and 12% milk that is needed to be mixed is 7.5 gallons and 12.5 gallons, respectively.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the amount of 20%milk mixed be represented by x, while the amount of 12% milk mixed is represented by y. Therefore, the two-equation can be written as,

x+y=20 gallons

0.20x + 0.12y = (0.15×20)

Solve the first equation for x, therefore,

x = 20 - y

substitute the value of x in the second equation,

0.20(20-y) + 0.12y = 3

4 - 0.2y +0.12y = 3

-0.08y = -1

y = 12.5 gallons

substitute the value of y in the first equation,

x + 12.5 = 20

x = 7.5 gallons

Hence, the amount of 20% milk and 12% milk that is needed to be mixed is 7.5 gallons and 12.5 gallons, respectively.

A triangular pyramid has 6 edges, 4 vertices, and 1 base

The quadrilateral is a trapezoid and the area of the quadrilateral is 85.04 square units

The vertices are given as:

A:(-2, 3) B:(4, -6) C:(10, 2) D:(6, 8)

Next, we plot the vertices (see attachment)

From the attached graph, we can see that the quadrilateral is a trapezoid

From the plot, we have the following features:

Height: AD

Parallel sides: CD and AB

Calculate the lengths using:

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]

So, we have:

[tex]AD = \sqrt{(-2 -6)^2 + (3 -8)^2}[/tex]

[tex]AD = \sqrt{89}[/tex]

[tex]CD = \sqrt{(10 -6)^2 + (2 -8)^2}[/tex]

[tex]CD = \sqrt{52}[/tex]

[tex]AB = \sqrt{(-2 -4)^2 + (3 +6)^2}[/tex]

[tex]AB = \sqrt{117}[/tex]

The area is then calculated as:

Area = 0.5 * (CD + AB) * AD

This gives

Area = 0.5 * (√52 + √117) * √89

Evaluate

Area = 85.04

Hence, the area of the quadrilateral is 85.04 square units

Answer:

[tex]20cm^2[/tex]

Step-by-step explanation:

We are talking of a linear scale ie 1 cm = 50 cm

So if the real yacht length is 10 meters(10,000 cm), then the model length will be 10000/50 = 200 cm

However, when talking about areas, the scale factor is different. We cannot simply divide 5m by 50

Let's say the sail height is 1 meter and the sail width is 5 meters which will give a sail area of 5 sqm.

The scaled height would be 100/50 = 2cm and scaled width will be 500/50 = 10 cm

So the area of the sail on the model will be 2 x 10 =200 square cm

In short, area of sail on model = (area of sail on real yacht( ÷ (50 x 50)

Since there are 10,000 square cm to 1 square meter we get the answer as 5 x 10000/2500 = 20 square cm
