In the figure below, m1 = (x+84)° and m2 = 2x°.
Find the angle measures.

By the figure of a circle, 70% of the figure is shaded.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

A circle divided into ten equal parts. Seven of the parts are shaded.

Now, Number of total parts = 10

And, Shaded parts of a circle = 7

Hence, The percent of shaded part is,

⇒ Shaded part / Total parts × 100

⇒ 7/10 × 100

⇒ 70%

Thus, There are 70% of the figure is shaded.

Answer:

Therefore, there is 8 children that is 9 years old and 6 children that is 11 years old.

Step-by-step explanation:

Let x be the no. of 9 years old and y be the no. of 11 years old.

x+y= 14 (1)

9x+11y= 138 (2)

From (1) :

x=-y+14 (3)

sub (3) into (2) :

9(-y+14)+11y= 138

-9y+126+11y=138

2y= 138-126

y= 6 (4)

sub (4) into (1) :

x+6= 14

x= 8

Let pp be the number of players. We can write an equation to solve for the number of players.

1581.75 - 968.50 - (pp × 55.75) = 0

1581.75 - 968.50 - 55.75pp = 0

-55.75pp = -613.25

pp = 11

Therefore, the team can bring 11 players to the tournament. To find this, we subtracted the cost of the bus (968.50) and the cost of meals per player (55.75pp) from the total amount raised (1581.75).

We then divided both sides by -55.75 to solve for the number of players (pp) on the team.

You would need a sample size of 384 in order to create a population proportion with a margin of error of no more than 0.025 and a 95% confidence interval.

In order to calculate the sample size needed for a 95% confidence interval with a margin of error of no more than 0.025, the formula to use is the following:

[tex]n = (z-score)^2 * p * (1-p) / (margin of error)^2[/tex]

Where n = sample size, z-score = 1.96 (for 95% confidence interval), p = 0.5 (the expected population proportion) and margin of error = 0.025.

Substituting these values into the equation, we get:

[tex]n = (1.96)^2 * 0.5 * (1 - 0.5) / (0.025)^2\\n = 384[/tex]

Therefore, you would need a sample size of 384 in order to create a population proportion with a margin of error of no more than 0.025 and a 95 %  confidence interval.

The answer is 25. 25 is the heaviest possible weight for pack i.e. for d among pack of a, b, c, and d.

let (a, b, c, d) be the packs sorted from lightest to heaviest.

The following four equations must hold:

a + b = 34

a + c = 37

b + d = 43

c + d = 46

we then have a pair of equations which can be satisfied in two ways:

b + c = 39 and a + d = 41

or

b + c= 41 and a + d = 39

Solving the first set of 6 equations gets:

(a, b, c, d) = (16, 18, 21, 25)

Solving the second set gets:

(a, b, c, d) = (15, 19, 22, 24)

The function f(x) is the sloping trail, it is the ratio of the change in the trail's height over the change in the trail's length.

It is the same as the rate of change of an evaluation of the trail, which is the derivative of a function that gives us the elevation. Thus, for a function F(x) that gives us the elevation, f(x)=F(x).

When we integrate a derivative, we can form a rate of change to total change. Thus integrating f(x) over an interval then the total change in elevation within that interval.

In this case, we will have to solve the integral:

[tex]\int\limits^9_7 {f(x)} \, dx[/tex]

The bounds of integration are 7 to 9, so this calculates the total change in elevation between 7 to 9, which is the total change in the elevation in the first seven miles of the trail.

The probability of a card being black given it is a queen is P(A|B) = P(A ∩ B) / P(B) = (4/52) / (4/52) = 1. This means that if you draw a queen from a standard deck of 52 cards, it will be black with a probability of 100%.

The probability of a card being black given it is a queen can be determined using the formula P(A|B) = P(A ∩ B) / P(B). Where P(A) is the probability of a card being black and P(B) is the probability of a card being a queen.

To calculate this, we first need to calculate the probability of a card being a queen, which is 4/52 (there are 4 queens in a standard deck of 52 cards). The probability of a card being black is 26/52 (there are 26 black cards in a standard deck of 52 cards).

Using the formula, the probability of a card being black given it is a queen is P(A|B) = P(A ∩ B) / P(B) = (4/52) / (4/52) = 1. This means that if you draw a queen from a standard deck of 52 cards, it will be black with a probability of 100%.

A day on the moon (from sunrise to sunrise) is approximately 29.5 Earth days or about 23 hours and 56 minutes.

A day on the moon, known as a "lunar day," lasts approximately 29.5 Earth days.

This means that it takes 29.5 Earth days for the moon to rotate once on its axis and complete one full rotation.

This is due to the fact that the moon rotates very slowly and takes a long time to complete one full rotation. It is also worth noting that a lunar day is also referred to as a "synodic month" and that a lunar day is longer than a solar day,

which is the time it takes for the sun to return to its highest point in the sky. The length of a solar day on the moon is about 23 hours and 56 minutes.

The third side may be 6 or 9 metres long, or it may be between 9 and 15 miles long.

Depending on the lengths of the other two sides, the triangle's third side can have a variety of lengths. The third side's length could range from 9 to 15 metres if the first two sides are 6 and 9 miles, respectively. The reason for this is that the length of any two sides of a triangle must always be greater than the length of the third side; in this instance, the sum of the two sides is 15 metres, or 6 and 9 metres. As a result, the triangle's third side must be either less than or equal to 15 metres. A triangle can also have two equal sides, so the third side could also be equal to 6 or 9 metres.

Answer:

x = -4, y = 7

Step-by-step explanation:

The two equations are:

5x + y = -13  ... (1)

-5x - 6y = -22 ...(2)

Isolate for x in (1)

5x + y = -13

5x = -13 -y

x = (-13-y)/5

Substitute this value of x into equation (1) -5x - 6y = -22

-5 · (-13-y)/5 -6y = -22

-1(-13-y) - 6y = -22

13 + y -6y = -22

y - 6y = -22 - 13

-5y = - 35

y = -35/-5 = 7

Substitute y = 7 in equation 1
5x + 7 = -13

5x = -13 - 7

5x = -20

x = 20/-5 = -4

Ans:

x = -4, y = 7
