Answer:

n=1/3

Step-by-step explanation:

Answer:

There’s no error

Step-by-step explanation:

The value of y in simplest form for the point P = (1/2, y) lying on the unit circle is y = ± √(3)/2.

To find the value of y in simplest form for the point P = (1/2, y) lying on the unit circle, we can use the equation of the unit circle, which states that for any point (x, y) on the unit circle, the following equation holds: x^2 + y^2 = 1.

Plugging in the coordinates of the point P = (1/2, y), we get:

(1/2)^2 + y^2 = 1

1/4 + y^2 = 1

y^2 = 1 - 1/4

y^2 = 3/4.

To simplify y^2 = 3/4, we take the square root of both sides:y = ± √(3/4).

Now, we need to simplify √(3/4). Since 3 and 4 share a common factor of 1, we can simplify further: y = ± √(3/4) = ± √(3)/√(4) = ± √(3)/2.

Answer: 4.5 litres

Step-by-step explanation:

If 1.5 liters of red paint is mixed with white paint to make 6 liters of pink paint, then the ratio of red paint to the total mixture is 1.5/6 = 0.25.

Since the pink paint is made by mixing red paint with white paint, the ratio of white paint to the total mixture is 1 - 0.25 = 0.75.

Therefore, to find the amount of white paint needed, we can set up the following proportion:

1.5/0.25 = x/0.75

Solving for x, we get:

x = 0.75 * 1.5 / 0.25 = 4.5

So, 4.5 liters of white paint is needed to make 6 liters of pink paint.

Hi!

If 6 liters were to be made, and 1.5 liters of red is needed, then we would subtract 1.5 from 6 to get your final answer
6 - 1.5 = 4.5.
So, 4.5 liters of white will be needed to make 6 liters of paint.

The sum of the geometric series is 306. We can start by finding the first term and the common ratio of the geometric series.

The first term is 54, and to find the common ratio we divide any term by its previous term:

36 / 54 = 2/3

(2/3) * 54 = 36

128/27 / 36 = 4/3

So the common ratio is 2/3.

S = a * (1 - r^n) / (1 - r)

where S the sum of a geometric series with first term a,  common ratio r, and n terms is no. of terms.

We are given that there are seven terms in the sum, so n = 7.

Using the values we have:

S = 54 * (1 - (2/3)^7) / (1 - 2/3)

S = 54 * (1 - 128/2187) / (1/3)

S = 54 * (2059/2187) * 3

S = 306

Therefore, the sum of the geometric series is 306

The perimeter of the shaded shape is 44m

Perimeter is the outside boundary of a shape.

The formula for calculating the perimeter of most quadrilaterals is just to sum the lengths of the shape.

From the figure, above some lengths were not given a dimension, it is expected that it is figured out.

The L-section has 6 sides and  the following dimension, 14m, 4m, 9m, 8m were given for the 4 sides.

To get the dimension of the remaining two sides,

The base is 8m, so smaller base = (8 - 4) = 4m

the other dimension = (14 - 9) = 5m

The perimeter of the shape becomes 14 + 4 + 9 + 8 + 4 + 5 = 44m

In conclusion the perimeter of the L-cross section is 44m

Answer:

I don't get this..

Step-by-step explanation:

Mr. Cho received 3840 eggs in the beginning.

Let's assume that Mr. Cho received x eggs in the beginning.

In the morning, he sold 1/3 of the eggs, so he had 2/3 of the eggs left. Therefore, he had 2/3 x eggs left after the morning sales.

In the afternoon, he sold 320 eggs, so he had 2/3 × x - 320 eggs left at the end of the afternoon.

At the end of the day, he found that 1/4 of the eggs were not sold, which means that he had 3/4 of the eggs left. Therefore, we have:

3/4 × x = 2/3 × x - 320

Multiplying both sides by 12, we get:

9x = 8x - 3840

Simplifying, we get:

x = 3840

Therefore, Mr. Cho received 3840 eggs in the beginning.

Answer:

x = 3/2 or x = -1

Step-by-step explanation:

2x² - x - 3 = 0

2*(-3) = -6

Factors of -6:

(-1, 6), (1, -6), (-2, 3), (2, -3)

We need to find a pair that adds up to the co-eff of x which is (-1)

Factors :(2,-3)

2 - 3 = -1

so, 2x² - x - 3 = 0 can be written as:

2x² + 2x - 3x - 3 = 0

⇒ 2x(x + 1) -3(x + 1) = 0

⇒ (2x - 3)(x + 1) = 0

⇒ 2x - 3 = 0 or

x + 1 = 0

⇒ 2x = 3 or x = -1

⇒ x = 3/2 or x = -1

The value of x is 4 and 0

Answer:

$18.40 is the final cost

Explanation:

Multiply 15% and 16 and add the product with 16.

The angle in degrees is 873.1843.

Let the measure of the angle be θ in degrees. Therefore, the measure of the same angle in gradians is (θ × π/180).

According to the given information, the number of degrees of a certain angle added to the number of gradians of the same angle is 152.(θ) + (θ × π/180) = 152.

Simplifying the above equation, we get:(θ) + (θ/180 × π) = 152.

Multiplying both sides of the equation by 180/π, we get:

θ + θ = (152 × 180)/π2θ = (152 × 180)/πθ = (152 × 180)/(3.14)θ = 873.1843

Thus, the angle in degrees is 873.1843.

To check if (-5,6) is a solution to the equation y=-7, we need to substitute -5 for x and 6 for y in the equation.

If the equation is true, then the ordered pair is a solution to the equation.

If we put (-5,6) into y=-7, we get 6=-7, which is not true.

So, (-5,6) is not a solution to the equation y=-7.

Step-by-step explanation:

Ana will spend K23.94 for 21 days.

To calculate how much Ana will spend for 21 days, we need to determine the cost per day and then multiply it by the total number of days.

Since Ana spends K8.00 per week, we can find the daily cost by dividing the weekly cost by the number of days in a week.

Cost per day = K8.00 / 7 days = K1.14 (rounded to two decimal places)

Now, we can calculate how much Ana will spend for 21 days by multiplying the cost per day by the total number of days.

Total spending = K1.14 * 21 days = K23.94

Therefore, Ana will spend approximately K23.94 for 21 days.

It's important to note that we rounded the cost per day to two decimal places. In real-life scenarios, Ana may have to pay the nearest whole currency amount per day. Therefore, the actual total spending might differ slightly depending on the rounding or any variations in the daily cost.

The value of x in degrees will be 6° and 11° using properties of parallel lines.

They are typically equal-distance, parallel straight lines. The lines here are parallel. They never come together no matter how far you extend them in any one way.

Pairs of equal-sized angles that are both obtuse or acute and are generated on the same side of the transversal are known as corresponding angles. Each pair of comparable angles on the same side of the crossing transversal is equal to the other.

The alternative angle theorem states that alternate interior angles or alternate exterior angles that come from cutting two parallel lines are congruent.

In the above figure,

8x + 7 = 55

8x  = 55 - 7

x = 6

Measure of the angle will be 8 × 6 + 7 = 49
