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 volumeLet 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

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
============================================
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.

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

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

Answers
Answer:
Linda, Julie, Jenna, Karl
Step-by-step explanation:
Here, we want to list the students in order from lowest to highest
The key here is to have the scores in the same form, let us say decimals for ease of comparison
Jenna: 85% = 85/100 = 0.85
Linda’s= 32/40 = 80% = 0.8
Karl = 7/8 = 0.875
Julie = 0.83
So from lowest to highest, we have;
