Area of shaded region = 2 × (Area of a trapezium)

    = 2 × [tex]\frac{1}{2}[/tex] × (Sum of parallel sides) × (perpendicular height of trapezium)

suppose v varies directly as g , and = 70 when v=30. Find v when g=9

Answers

Answer:

v = 21

Step-by-step explanation:

Suppose v varies directly as g, meaning that there is a constant k such that v = kg. If v = 70 when g = 30, then we can use this information to find the value of k:70 = k * 30k = 70 / 30k = 7 / 3Now that we have the value of k, we can use it to find v when g = 9:v = kgv = (7 / 3) * 9v = 21So when g = 9, v = 21.In conclusion, by finding the value of the constant of proportionality k and using the formula v = kg, we determined that when g = 9, v = 21.

According to a Manila police, two people were killed when the 1,000 kg car illegally drag racing at a speed of 30 m/s had a head on collision with a 2,000 kg truck whose driver fell asleep as it traveled 20 m/s. Which vehicle has received the greater force?

Answers

Answer: To determine which vehicle received the greater force, we need to calculate the momentum change for each vehicle during the collision. The force experienced by a vehicle during a collision is equal to the rate of change of its momentum.

First, let's calculate the initial momentum for each vehicle:

The car has a mass of 1,000 kg and a velocity of 30 m/s, so its initial momentum is 1,000 kg * 30 m/s = 30,000 kg m/s.

The truck has a mass of 2,000 kg and a velocity of 20 m/s, so its initial momentum is 2,000 kg * 20 m/s = 40,000 kg m/s.

Next, let's calculate the final momentum for both vehicles after the collision:

The car and truck collide head-on, so their velocities will become zero after the collision. So the final momentum for both vehicles will be zero.

Finally, we can calculate the rate of change of momentum for each vehicle:

The rate of change of momentum for the car is equal to its final momentum minus its initial momentum, or 30,000 kg m/s - 0 kg m/s = 30,000 kg m/s.

The rate of change of momentum for the truck is equal to its final momentum minus its initial momentum, or 0 kg m/s - 40,000 kg m/s = -40,000 kg m/s.

Since the magnitude of the rate of change of momentum for the truck is greater than the magnitude of the rate of change of momentum for the car, the truck has received the greater force.

What is the cost and area of the mat

Answers

The costs and areas of the mat are

Mat area = 2x + 2y + 4; Cost = 0.1x + 0.1y + 0.2Mat area = 4x + 4y + 16; Cost = 0.2x + 0.2y + 0.8

How to determine the cost and area of the mat

Represent the dimensions of the frame with

Length = x

Width = y

So, the frame area is

Area = xy

When the mat is 1 inch from the frame, we have

Whole Area = (x + 1 + 1) * (y + 1 + 1)

Whole Area = (x + 2) * (y + 2)

Expand

Whole Area = xy + 2x + 2y + 4

So, the mat area is

Mat area = xy + 2x + 2y + 4 - xy

Mat area = 2x + 2y + 4

The cost is

Cost = 0.05 * (2x + 2y + 4)

Cost = 0.1x + 0.1y + 0.2

When the mat is 2 inches from the frame, we have

Whole Area = (x + 4) * (y + 4)

Expand

Whole Area = xy + 4x + 4y + 16

So, the mat area is

Mat area = xy + 4x + 4y + 16 - xy

Mat area = 4x + 4y + 16

The cost is

Cost = 0.05 * (4x + 4y + 16)

Cost = 0.2x + 0.2y + 0.8

The "magic number" in baseball is used to estimate how likely a club is to advance to the postseason or win the division. Every year, in September, when teams get closer to clinching, it gains attention. The total number of victories and losses that must occur by a team's closest rival in order for that team to achieve a certain goal is known as its magic number. A team's magic number drops by one with each victory. The magic number additionally drops by one each time the team's closest rival for the division (or Wild Card) loses.

This is the precise formula: Games left in season: +1 (Losses by second place team - losses by first place team)

The magic number changes to reflect any further changes in the second-place team.

Write an expression that represents the area of

Answers

The expression that represents the area of each section is 14.2z - 9.8.

What is area ?

To find the area of each section, we need to divide the total area of the garden plot by the number of sections, which in this case is six.

The expression for the area of each section can be obtained by dividing the expression for the total area by 6:

(area of each section) = (total area of garden plot) / 6

(area of each section) = (85.2z - 58.8) / 6

Simplifying this expression, we can divide both terms by 6:

(area of each section) = 14.2z - 9.8

Therefore, the expression that represents the area of each section is 14.2z - 9.8.

The false statement is (a) P( A^c n B^c)=P(A^c) P(B^c). The probability of the intersection of complements is generally not equal to the product of individual complements.

The misleading assertion including p, and the erratic occasions An and B is (a) P( A^c n B^c)=P(A^c) P(B^c).

This assertion is bogus in light of the fact that by and large, the likelihood of the convergence of the supplements of two occasions, A^c and B^c, isn't equivalent to the result of their singular supplements.

For instance, assume we flip a fair coin. Let A be the occasion of getting heads and B be the occasion of getting tails. Then, P(A) = P(B) = 1/2, so P(A^c) = P(B^c) = 1/2. In any case, A^c and B^c are a similar occasion (getting heads or tails, separately), so P(A^c n B^c) = P(A^c) = 1/2. Then again, P(A^c) P(B^c) = (1/2)(1/2) = 1/4, which isn't equivalent to P(A^c n B^c).

what is 250lb in kg ?

Answers

Using the formula to convert pounds to kilogram,

We know that :

1 lb/ Pound = 0.453592 kilogram

therefore,

250 lbs/ Pound = 113.398 kilogram.

Using the formula to convert pounds to kilograms, you find that 250 pounds equals 113.398 kilograms

To convert 250 pounds (pounds) to kilograms (kg), you must use the conversion factor 1 pound = 113.398 kilogram.

Therefore,

we multiply 250 pounds by 86.18 kg/lb to get the equivalent weight in kilograms:

250 pounds x 0.45359237 kg/lb = 113.398 kilogram

Therefore,

250 pounds is 113.4 kilogram.

To understand the conversion factor, you need to know that pounds and kilograms are units of mass, but are used in many parts of the world. In the United States and some other countries, the accepted unit of mass is the pound, while most other countries use the kilogram.

A conversion factor connects the number of pounds to the number of kilograms, so you can easily convert from one unit of measure to another. It is important to use the correct conversion factor for accurate conversion.

At the concrete level, I would introduce the concept of more than/less than with a hands-on activity. For example, I would have students compare the number of counters or blocks and have them determine which group has more or less. This would help them develop a fundamental understanding of the concept.At the semi-concrete level, I would introduce the concept of more than/less than with written numerals. I would have students compare numbers on paper, such as 4 and 6, and have them determine which number is more or less. I would also ask them to use concrete objects to represent the numbers, such as using four counters for 4 and six counters for 6.At the abstract level, I would introduce the concept of more than/less than with larger numbers. I would ask students to compare numbers such as 12 and 15, and determine which number is more or less. I would also ask them to use abstract symbols, such as 12 + and 15 -, to represent the numbers.By using this step-by-step approach, students will be able to move from the concrete level to the semi-concrete and finally to the abstract level of understanding the more than/less than concept. This will help them develop a strong foundation of the concept, which will allow them to solve more complex problems in the future.
