Answers

Answer 1

Answer:

150

Step-by-step explanation:

P = total distance

find the remaining distance which is

9- 4 = 5cm

6-4 = 2cm

P= 4+9+6+4+2+5

P= 30cm

Actual Perimeter

1cm = 5m

30 cm=?

30*5 = 150m

Answers

Answer:

see explanation

Step-by-step explanation:

Consider the left side

(Acosx + Bsinx)² - (Bcosx + Asinx)² ← expand factors using FOIL

= A²cos²x + 2ABsinxcosx + B²sin²x - (B²cos²x + 2ABsinxcosx + A²sin²x)

= A²cos²x + 2ABsinxcosx + B²sin²x - B²cos²x - 2ABsinxcosx - A²sin²x

= A²cos²x - Bcos²x + B²sin²x - A²sin²x ← factor first/second and third/fourth terms

= cos²x(A² - B²) - sin²x(A² - B²) ← factor out (A² - B²) from each term

= (A² - B²)(cos²x - sin²x)

There is a bag with only red marbles and blue marbles.

The probability of randomly choosing a red marble is 2/7







There are 16 red marbles in the bag and each is equally likely to be chosen.

Work out how many marbles in total there must be.

Answers

Answer: 56

Step-by-step explanation:

Given that :

Marbles in bag are only red and blue ;

Probability of randomly choosing a red = 2/7

Number of red marbles in bag = 16

The total Number of marbles =?

P(choosing a red marble) = required outcome / Total possible outcomes

Required outcome = number of red marbles

Total possible outcomes = total number of blue and red marbles

Total number of blue and red marbles = x

P(choosing a red marble) = required outcome / Total possible outcomes

2/7 = 16 / x

Cross multiply

2x = 16 * 7

2x = 112

x = 112 / 2

x = 56 marbles

Total number of marbles = 56

Raina drank 5 L 400 ML of water on the first three days of the week each. The next 2 days she drank 3 L each and the remaining days of the week she drank only 1.500 L each . How much water did she drink in that one week?

Answers

Answer:

She drank a total of 17 L 400 ML

Step-by-step explanation:

Here, we want to know the amount of liters of water drank in the week

In the first three days;

5L 400 ML;

Next two days 3 L each = a total of 6 L

Remaining 4 days; 1.5 L each which is a total of 4 * 1.5 = 6 L

Total amount drank will be;

6 + 6 + 5L 400 ML

= 17L 400 ML

Find the missing value. 7/8 = x/28.8 Please help, I clearly have no brain cells left, and I have the brain capacity of a Carrot ;-;

Answers

Answer:   x = 25.2

============================================

Work Shown:

7/8 = x/28.8

7*28.8 = 8*x .... cross multiply

201.6 = 8x

8x = 201.6

x = 201.6/8 ... divide both sides by 8

x = 25.2

The missing value of x is 25.2.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Let the missing value is x.

Given:

7/8 = x/28.8

7(28.8) = 8x

Cross multiply;

201.6 = 8x

8x = 201.6

x = 201.6/8

Divide both sides by 8;

x = 25.2

Hence, The missing value of x is 25.2.

Two boats, A and B, are approaching a port. The distance between the boats is 12 miles. The bearings of the port with respect to boat A and boat B are N 60° W and N 35° E respectively. How far is boat A from the port? A. 11.02 miles B. 9.87 miles C. 8.23 miles D. 4.54 miles

Answers

The distance from boat A to the port is approximately 5.196 miles.

Let's let point P represent the port.

Here A represent boat A and B represent boat B.

It is also given distance between A and B as 12 miles.

Next, we are finding the angles which boat A and boat B make with the line connecting them.

Let's call this line AB.

We can find these angles by subtracting the given bearings from 180 degrees.

For boat A, the angle it makes with AB is 180° - 60° = 120°

For boat B, the angle it makes with AB is 180° - 35° = 145°

Now we can use trigonometry to find the distance from boat A to the port. Let's call this distance x.

We can use the law of sines, which states

sin A / a = sin B / b = sin C / c

where A, B, and C are angles of a triangle and a, b, and c are the side lengths opposite those angles.

In our case, we can use the angle at boat A (which is 60 degrees) and the angle at the port (which is 120 degrees) along with the side opposite the angle at boat A (which is x) and the side opposite the angle at the port (which is 12-x), sin 60° / x = sin 120° / (12 - x)

We are Simplifying,

√3 / x = √3 / (12 - x)

Multiplying both sides by x(12-x),

12√3 - 3x√3 = x√3

Simplifying further,

12√3 = 4x√3

Dividing both sides by 4√3,

x = 3√3

Therefore, the distance from boat A to the port is approximately 5.196 miles.

A cylinder shaped container is used to hold watef . This cylinder has a height of 12 inches and a diameter of 7 inches . A spherical ball with a diameter of 6 inches is dropped into the container . Explain how the ball changes the volhme of the water the container can hold and calculate the amount of water the cylinder can hold after the ball is dropped into the cylinder . Let pi = 3.14

Answers

Answer:

423.9 inches³

Step-by-step explanation:

First we will calculate the volume of the cylinder using the formula

Vc = hπr²

Vc = 12π(3.5)²     [radius is 1/2 diameter]

Vc = 147π

Next we calculate the volume of the sphere using 4/3*πr³

Vs = 4/3 πr³

Vs = 4/3π3³

Vs = 12π

Finally, we subtract the volume of the cylinder by the volume of the sphere to get the remaining volume in the cylinder that can be filled with water.

147π - 12π = 135π

Using the approximate 3.14, the answer is 423.9 inches³

The Smith family is trying to decide what theme park to visit on their vacation. Family Fun Land costs $12 per person and $40 for parking. Blue Jay Bay costs $22 per person and $12 for parking. Explain their different options depending on how many people go.

Answers

Answer: For groups with over 3 people, Family Fun Land is the best option. It's cheapest for groups of 1 or 2 to go to Blue Jay Bay.

Step-by-step explanation:

Family Fun Land | y = total $, x = # of people

y = 12x + 40

Blue Jay Bay

y = 22x + 12

2 People

y = 12(2) + 40

y = 64

y = 22(2) + 12

y = 56

3 People

y = 12(3) + 40

y = 76

y = 22(3) + 12

the mass of a 30 cm³ stone is 180 g , find it's density​

Answers

Answer:

The density of the stone is 6 g/cm³

Step-by-step explanation:

The rule of denisty is d = M ÷ V, where

M is the massV is the volume

Let us use this rule to solve the question

∵ The volume of the stone is 30 cm³

∴ V = 30 cm³

∵ The mass of the stone is 180 grams

∴ M = 180 g

→ Substitute them in the rule above to find d

∵ d = 180 ÷ 30

∴ d = 6 g/cm³

∴ The density of the stone is 6 g/cm³
